Updated: 07 April

With lockdown measures easing across the country, you may be using your car for the first time in a while very soon.

If you’ve not been driving regularly during the COVID-19 lockdown, your car may need some attention before you hit the road. That’s because some car parts rely on regular use to stay in tip-top shape.

Follow these tips and there’s a much greater chance your car will start first time after a lockdown lay-up.

1. Look after your battery

The first COVID-19 lockdown showed just how important it is to look after your battery.

During the lockdown in April last year, over 60% of our callouts were for battery-based issues. In April of the year before, it was only 26%. So, this shows that sitting idle can have a huge impact on your vehicle’s battery.

This is no surprise, as when a car sits unused for a long time, the battery can go flat. That will mean the starter motor can’t do its job and you’ll go nowhere fast.

Cars use a component under the bonnet called an alternator that draws power from the engine to automatically recharge the battery. How long the battery holds that charge depends largely on its age. A new, healthy battery should be able to go unused for at least a few weeks without losing all its charge. Older batteries will need some help to get them through not being used, particularly in very cold weather.

So, make sure you start your car once a week and let the engine run for 20 minutes.

This will charge the battery. But remember to turn off features that draw current from the battery, such as lights and wipers, while you’re doing this.

It’s important that you only access your vehicle when you really need to. Every time you unlock your vehicle, it can ‘wake the vehicle up’ and start the use of electrical components, which reduces your battery charge. One easy way to use less power is to keep your door shut if you’re cleaning inside your vehicle, as this will stop your interior lights from switching on.

Stay with the car at all times while the engine is running and keep an eye on the temperature gauge, if the car has one. The engine shouldn’t overheat but it’s best to be on the safe side.

You could also use a battery charger, if you have one. Some modern battery chargers are designed to condition batteries and then keep them in the best possible shape. Make sure you connect and disconnect any charger according to the manufacturer’s guidelines, and only do this if you have the right equipment and knowledge to do so.

To find out how to charge your battery if it has gone flat, read our simple guide here.

2. Regularly start and move your car

Watch a quick run-through of how to look after your vehicle.

Starting your car regularly isn’t just good for your battery, it’ll help your brakes and air-con as well.

Corrosion building up between the brake’s pads and discs makes them stick on. Moving the car backwards and forwards at least once a week should prevent this from happening. Obviously, make sure it’s safe to do this first.

The air conditioning in most new cars uses the coolant that flows through it to lubricate its seals. If the air con goes unused for a period, those seals can dry out and cause leaks. When you start your car to charge the battery, make sure the air con is switched on too.

3. Keep your tyres pumped up and your tank full

Ensuring your tyres are at the correct pressure for your car will keep them in good shape.

If you don’t have your own pressure gauge and pump, they’re a great investment. Otherwise, as soon as you drive your car again, take it to a garage forecourt and check and inflate the tyres where necessary.

If you need new tyres, find the exact ones your vehicle needs at Green Flag Tyres.

Also, make sure you fill your car with fuel, if you can.

The fuller a car is with fuel when it’s left, the better. Both petrol and diesel can degrade when left for long periods, but this only happens when they’re exposed to air. The more fuel a car has, the less air there is.

With a fuller tank, there’s also less chance of condensation building up. That said, fuel shouldn’t start to deteriorate unless the car is left unused for a year or more

4. What to watch out for when you get behind the wheel

Before you go anywhere, check the fluids beneath the bonnet. This includes engine oil, coolant, brake fluid, power steering fluid and topping up the windscreen washer reservoir.

When you first drive the car, the parking brake may be locked on after you release the lever or switch. This will usually be because moisture trapped in the mechanism has stuck parts together. This should free when you drive off. Just be aware that when you first move the car, there might be a loud clunk from one of the wheels.

One thing to remember, your brakes will probably sound noisy when you first apply them. This is because there’s a layer of rust on the discs. It will clear after the first few times you apply the brakes, so there’s nothing to worry about.

5. Head out on a slightly longer trip

At some point during the first few days of driving regularly again, it may be worth taking your vehicle on a slightly longer trip.

If you’ve just been making shorter journeys, head down the motorway if you can, as it’ll let your engine hit operating temperature. Driving at higher speeds can actually have a cleaning effect on the emission control components in your exhaust, which is very handy after your vehicle’s been idle for a while.

What if you own an electric car?

Electric car batteries have clever computer management systems to ensure they last for years. But like any other battery, it’s not great for their long-term health to be fully charged then left for weeks.

If you must leave an electric car for a long period, it’s best to do so when its battery is between 45 and 55 per cent full. Then charge it fully just before you use it again.

If you’re planning on travelling, the Department For Transport has some important advice that’s well worth reading.

  7. David Vaughan 21/04/2020 4:17 PM

    I’ve disconnected the battery , as per the handbook. Is that ok..?

    • Kev owen 16/04/2021 6:05 PM

      Without battery power, you may need to reinitialise your radio when you come to reconnect it again. Also bear in mind without power, factory fitted security devices/ car alarms etc wont work.

  8. Mrs Jones 21/04/2020 4:23 PM

    Thats great advice, I had been wondering about the battery and brakes. Now I know I can easily take of them.

  35. Sheila 21/04/2020 8:13 PM


  36. Valerie Joint 21/04/2020 8:16 PM

    I wish I had had this information earlier as my car battery is now completely flat, I can’t even open the doors. I had kept petrol tank fairly full, checked the pressure and moved the car slightly to change the pressure on the tyres and put brakes on and off regularly, so was surprised when after only three weeks I had a flat battery. I live in a retirement home and have been doing exactly what advised and have not contacted anyone regarding my car, as I would not be able to use it anyway. So I will wait until things are mostly back to normal and then can I please contact you to arrange for someone to replace the battery and check the alternator etc for me? Thank you for being in touch, Valerie Joint

  37. Edward Jenkinson 21/04/2020 8:20 PM

    Some Of this advice is questionable, and certainly a consensus isn’t always reached. But starting weekly should not be required and starting an engine with no oil pressure is where engine damage occurs. Also why no advice to over inflate the tyres?

  38. Mike Cullis 21/04/2020 8:25 PM

    Great advice, thank you.

  39. Nicola White 21/04/2020 8:28 PM

    Great stuff. I will definitely give my car a bit of TLC. Didn’t actually realise how long since I’ve driven. Thanks for the reminder

    Many thanks your information was helpful and very much appreciated.

  66. Geoffrey Bower 22/04/2020 11:11 AM

    Extremely useful information as usual. I must admit that I didn’t know that a full tank of petrol is better than half a tank. I filled my car up well before the lockdown and It’s still over 3/4 full. Thank fully I’m getting more than 2 months to the gallon.

  67. Paul Kelley 22/04/2020 11:29 AM

    Sound advice and important for safety reasons to follow it. I run a classic car as well as a modern car and I keep both moving on a regular basis as advised. If you don’t start and move your car you will compromise its overall performance. a bit like us, they need ‘exercising’.

  68. Keith Ripley 22/04/2020 11:32 AM

    What about Hybrid cars? does the battery charge when the engine is running and the car is not moving?

    • Jack Stoker 20/05/2020 3:52 PM

      Hi Keith. Yes, hybrid vehicles are equipped with a smart charge system, which enables the batteries to be charged when a low voltage is detected. So, the batteries will still be charged, even if the vehicle is stationary.

  69. Ian Barker 22/04/2020 11:42 AM

    Thank you for clear, concise advice in plain English.

  70. Maureen Holman 22/04/2020 12:11 PM

    Thank you for these tips they are really helpful. I have been starting her up once a week and moving her out of the garage but hadn’t let her run for 20 minutes only about ten but will do that now.. I am lucky my car does not have the electronics the cars of today have so I’m not so worried about the battery more the engine although she is as-good-as-gold for an classic car “1984 2.8 injection Ford Capri” but I know she doesn’t like sitting in a garage as she is used to being driven/

    Very helpful. Thanks for the advice

  74. Teresa Hartley 22/04/2020 1:55 PM

    My battery is already flat. Since I am likely to be in self-isolation for weeks or months, it doesn’t seem worth asking you to come and charge it. Am I right?

  75. Frank 22/04/2020 1:57 PM

    can you charge the battery without disconnecting it from the engine in place in the garage ?

  76. mike nottingham 22/04/2020 2:51 PM

    thanks for the lockdown tips

  77. Mr.e Curley 22/04/2020 3:03 PM

    I was told by my garage to start my diesel vw once a week but only for a few minutes as leaving it running for 20 minutes idling could lead to a problem with the dpf filter ?

    • Jack Stoker 20/05/2020 3:55 PM

      Over time, using a vehicle for short journeys, or having it idle for long periods of time, can cause a build-up of soot in the Diesel Particulate Filter. Most manufacturers operate a warning lamp that’ll warn the driver when soot levels are getting high. The vehicle will then require a DPF regeneration, which usually consists of running the vehicle at 40/50 mph in a motorway setting in order to burn away the excess soot. It’s best to refer to your owner’s manual for vehicle-specific information regarding the regeneration process.

  78. David Reid 22/04/2020 3:12 PM

    Great, but what advice can you give motorcycle riders with regards their bikes and scooters?

  79. VeeTeasdale 22/04/2020 3:41 PM

    Very helpful advice, thank you. I had looked online but couldn’t find anything relevant.

  80. Keith Ripley 22/04/2020 3:48 PM

    What about a hybrid car? Will the battery be charging if it is started and runs for 20 minutes?

    • Jack Stoker 20/05/2020 3:53 PM

      Hi Keith. The batteries will be charging as long as the vehicle is switched on. Factors such as age and condition of the battery will determine if 20 minutes is long enough to charge it sufficiently. But, on average, 20 minutes should be long enough to sufficiently re-charge your battery.

  81. Lynne 22/04/2020 4:12 PM

    This is great advice. Thank you 🙂

  82. Sandra 22/04/2020 4:52 PM

    I am so grateful for your thoughtfulness. Thank you very much. What an excellent idea to tell us all of this. Bless you and keep safe.

  87. M Bell 22/04/2020 9:53 PM

    If I keep the car in a locked garage, is it better to not lock the car so the alarm is not activated thus reducing the amount of power drained from the battery
    I presume the alarm will use power from the battery?

  88. Erika Scott 23/04/2020 7:38 AM

    Many thanks for this advice. It was very informative

  89. Stella Ginella 23/04/2020 12:23 PM

    If your battery is already flat should you get it going with jump leads straightaway or leave it to the end of the lockdown?

  90. Art Zarb 23/04/2020 1:14 PM

    Thank you for all the tips, it may be a long time before I can use my car and my wife’s again so I shall certainly try to check on them every week.

  91. Richard Howard 23/04/2020 2:35 PM

    Your comments re running engine for 20minutes to recharge battery every week, does this apply equally to diesel & petrol cars?

    • Jack Stoker 20/05/2020 3:58 PM

      Hi Richard. Yes, both petrol and diesel cars recharge their batteries in the same way.

  92. Mrs Lena Clayton 23/04/2020 7:27 PM

    Thank you . These tips were very helpful as I was unaware of most of the problems that can occur when the car is not used for long periods.

  93. Ian Redman 24/04/2020 11:43 AM

    Thankyou for that very useful advice. Worth paying Green Flag for that alone

  99. Paul jones 29/04/2020 7:53 PM

    What about cars with stop start. Will 20 minute run time fully charge a battery. Stop start has stopped working on mine and last time it did this I needed a new battery. Any comments will help.

  100. Dennis Gee 03/05/2020 9:45 AM

    Very interesting,many thanks !
    All keep safe n well ?

  101. Brian 05/05/2020 8:50 AM

    Running your car if it is fitted with a DPF will not do it any good.20 minutes will do more harm than good and will clog the DPF up.

    • Jack Stoker 20/05/2020 3:56 PM

      Over a period of time, leaving a car idle can cause a build-up of soot in the DPF. Most manufacturers incorporate a warning system that illuminates a lamp to warn the driver of increased levels of soot in the DPF. If this happens, the vehicle will require a DPF regeneration, which is typically done by driving the vehicle at 40/50 mph in a motorway setting for a set period of time. It’s always best to refer to your owner’s manual for vehicle-specific information regarding the regeneration process.

  102. Alan Knight 05/05/2020 5:34 PM

    This is the best summary of care during lockdown that l have seen. Nobody else mentioned that the aircon should be switched on during the engine run,for example.ak

  103. Denis Congdon 05/05/2020 5:53 PM

    Thank you for these precautionary tips. Very helpful

    Thanks for the tips, like Ken it was news to me regarding the fuel capacity. I will run mine round the block tomorrow. I have really missed driving my car and it will feel like a treat just to drive again . Keep safe everyone God Bless Barbara Fleetwood .

  108. John A Scott 05/05/2020 6:59 PM

    Thank you for advice, only worried leaving car running could leave it running out of fuel, as I did not fill it up before lockdown. There’s just under 1/4 of tank left, 3 bars.

  109. Margaret 05/05/2020 7:04 PM

    Thank you great advice which I will follow.

  110. Sarah Jones 05/05/2020 7:35 PM

    My neighbours & my garage all tell me 20 mins is not enough for a Diesel engine & it should be warmed up thoroughly?

    • Jack Stoker 20/05/2020 3:59 PM

      Hi Sarah. This will depend on a few factors, such as the age and condition of your vehicle’s battery. On average, 20 minutes should be long enough to sufficiently re-charge your battery. The best way to get it fully charged is to use a battery charger, if you have access to one.

  111. Kate 05/05/2020 7:47 PM

    Great advice – thank you

    Information well received. Thank you for your time in putting this together.

  117. Beryl Champion 05/05/2020 8:25 PM

    Good advice. I have been giving my car a 50 mile drive once a fortnight when I go to collect shopping my daughter has done for me in the hope that is enough to keep it happy. Should I also move it up and down the drive in the intervening time? It’s a 10 year old car, but had a new battery last year.

  118. Joy Johnson 05/05/2020 8:27 PM

  125. martin bolger 05/05/2020 9:34 PM

    The garages are going to be busy with DPF issues with diesel cars! All short spins and no chance to imitate a regeneration

    • martin bolger 05/05/2020 9:35 PM


    • Jack Stoker 20/05/2020 3:57 PM

      Hi Martin. Short journeys are one of many reasons that can cause a build-up of soot in Diesel Particulate Filters. If the soot level increases to a specific level then garage attention may be required to perform a forced regeneration. So, always try to meet regeneration parameters as stated in your vehicle’s manuals as much as possible to help prevent the build-up of soot.

  126. Brian Dey 05/05/2020 9:50 PM

    Do you have any specific recommendations for a Yaris Hybrid

    • Jack Stoker 20/05/2020 3:51 PM

      Hi Brian. Toyota recommends that their hybrids should be left in ‘Ready Mode’ for around 60 minutes, at least once a week. This should be enough to sufficiently re-charge the batteries.

  127. Greg Halligan 05/05/2020 9:57 PM

    Did know most anyway, but can always learn more and most impressed that you’re providing this information. Thank You.

  128. Melvyn Saunders 05/05/2020 10:05 PM

    If I’m leaving my car unused for a long period, I leave it in reverse gear ( lowest gear) and leave the hand brake off. Not a good idea on a slope though!

  129. Sarah Lawson 06/05/2020 6:53 AM

    Would,you recommend leaving the car in gear when parking up for long periods and also parking on the flat.
    All really good advice.

  130. JEAN DAVIES 06/05/2020 7:14 AM

    I read somewhere to leave handbrake off and just
    put transmission in Park.
    Is this advisable

  154. Mr D Jones 09/05/2020 5:54 AM

    Rather than drive at a higher speed it is better to use a lower gear and higher than average engine speed, much safer and better for diesel engine vehicles.

    • Jack Stoker 20/05/2020 4:01 PM

      It’s always worth checking your owner’s manual for vehicle-specific information regarding the DPF regeneration process. Typically, vehicles would need to be driven at 40/50mph @ 2000-3000 rpm for at least 30 minutes. But, this can vary depending on the vehicle. Remember to have plenty of fuel in the vehicle, as it may not regenerate if the fuel level is low.

  155. Lee 09/05/2020 9:14 AM

    Helpful information and advice. Thank you.

  156. Carla Firman 09/05/2020 7:42 PM

    Unfortunately I had a flat battery after making several very short trips – but a very helpful technician was with me in no time, and recommended a battery charger which I can leave on all the time, keeping my battery in good shape. I found the one he suggested on Amazon and it arrived in a day – it has been connected by a motor mechanic friend, and is a big reassurance to me, and means that I am not polluting the now very clean atmosphere by running my car for 20 minutes a week without going anywhere. The advice about petrol is very useful and I will fill up soon!

    • Patricia 20/06/2020 12:14 PM

      Could you let me know the make of the battery?!

  157. Julie 09/05/2020 10:28 PM

  158. MARK VELARDE 11/05/2020 12:28 PM

    It’s all very well telling drivers to idle their engine fo 20 minutes but think about the polluting effect this has on the environment, even more so with diesel engines.
