Will my Toyota hybrid be okay if I don’t drive it?

As the UK government has instructed the nation to stay at home and only venture out for specific, essential reasons in light of the Coronavirus (Covid-19) situation, many of us are being encouraged to park our cars if we can. Some owners of Toyota hybrids might be wondering what will happen to their car during long periods without use, particularly when it comes to the level of charge in the batteries.

The reassuring news is that no difficult car maintenance is necessary. However, there are some tips that, if followed, can help ensure your Toyota remains in tip-top condition during an extended layoff.

To recap, Toyota hybrids generally contain two batteries: a 12-volt battery (which powers systems such as the headlamps and audio) and a high-voltage hybrid system battery (which supplies the power to start the combustion engine and drive the electric motors).

The simplest way to maintain charge in both of these batteries is to simply go through the normal start procedure: press the ‘Start’ button with your foot on the brake and ensure the ‘Ready’ light is illuminated on the dashboard (you don’t have to keep your foot on the brake thereafter, but ensure your vehicle’s transmission is in ‘Park’ and the parking brake is engaged).

We recommend you put the car in ‘Ready’ mode for about 60 minutes before switching it off again and repeat the process at least once a week, providing you can carry out this procedure while adhering to the government’s advice regarding social distancing and Coronavirus (Covid-19). Please do not leave your car unattended when it is in ‘Ready’ mode.

During the time that that car is in ‘Ready’ mode, you may hear and feel the internal combustion engine kick in; this is a normal part of the self-charging process. You might be tempted to switch on the radio to pass the time, or turn on other systems, but bear in mind these will consume small amounts of electrical power so it is preferable to leave them off.

Ensure the handbrake is on; there’s no need to go for a drive, although we must stress that this procedure should take place in a well-ventilated area – something to consider if you park your vehicle in a garage.

What if my Toyota isn’t a hybrid?

Our petrol and diesel cars only have a 12-volt battery, which provides the power to start the engine in addition to the other systems mentioned above. Regular start-up of the vehicle on conventional petrol and diesel engines needs approximately 20 minutes of running to put back into the battery what you remove on start up, so to maintain this battery we would suggest 60 minutes of running at least once a week.

Is there anything else I need to do?

Whether you own a hybrid or a Toyota equipped solely with an internal combustion engine, there are a few other easy car maintenance points that can ensure your Toyota hybrid remains healthy and happy during an enforced hibernation. Again, please adhere to the latest government advice regarding social distancing.

  • Check the tyre pressures are fully inflated to the recommended level and top-up if necessary. It can be a good idea to repeat this process when you first drive your car after a long period of inactivity.

  • Clean the car thoroughly inside and out. If you are storing your car in a garage, make sure the vehicle is completely dry before you put it away.

  • If you do plan to store your car in a garage, ensure the chosen storage area offers plenty of ventilation. If the space is secure, you could consider opening one of the car’s windows a small way to ventilate the interior. If you do this, you might have to change your car alarm’s setting to prevent it setting off the intrusion sensor – please consult your car’s manual for more information.

  • It can be beneficial to leave the vehicle with the parking brake disengaged to prevent the brakes from binding, but only do this if you are certain the car is on level terrain and isn’t going to move. Ensure the transmission is set to ‘P’ for park and place wedges or chocks, if you have them, under the wheels.
  • If you have a 12V battery trickle charger, or a solar panel charger, and are confident using them, then these are a good option to keep the battery fully charged while the vehicle is stationary for a period of time.
  • If your vehicle is equipped with smart entry and start but the system isn’t operated for a long time, a battery-saving function will automatically be activated to prevent the electronic key battery and the 12-volt battery from being discharged. Battery depletion in the key is minimised by stopping the electronic key from receiving radio waves. On many models equipped with this system, it is possible to manually put the key into battery-saving mode, so please consult your car’s handbook for more information. If you aren’t planning to drive your car for a long time, consider putting the smart key in a safe place and not carrying it around with you in your pocket. This will prevent the car from ‘waking up’ unnecessarily should you happen to walk near it in your garage or driveway.
  • If the vehicle will be kept on private property (such as inside a garage) for the duration of its storage, you could consider applying for a Statutory Off Road Notification (SORN). This informs the DVLA that the car is off the road and you will receive a refund of any remaining full months of tax. However, you won’t be able to drive your car legally until you tax it again, so it is only advisable if you are positive you won’t use your car for a long time.

  1. A “battery drain” has been a consistent problem with our hybrid over the five years we’ve had it. To be fair, Steven Eagle in Cambridge repeatedly gave us a new battery saying that the old one was faulty. But the problem was never addressed. I took the vehicle in a few days ago and the senior service manager was very helpful and communicative on the first day. Then there were no updates at all on the second day. This morning, I telephoned and was told by an employee that the senior service manager was busy and could he help. I explained that we had brought the car in for a “While you Wait” appointment a couple of days ago and were going to a funeral today so would appreciate an update. An employee launched into a a raised and emphatic “tirade” about *all* cars suffering from battery drain. I said this was not my experience in 50 years of motoring. I didn’t need a bully on the day of the funeral. Guess we’ll just have to continue with the jump starters.

    UPDATE

    My subsequent interaction with the senior service manager acknowledged my frustrations and whilst not solving my battery drain problem at least was focussed on providing some advice on how I might manage the ongoing problem.

    1. Hi,

      firstly, we’d like to apologise for your loss and for your experience during this hard time. If you’d like to make a complaint about your treatment, our customer relations team can be reached here:

      Due to the equipment onboard modern vehicles, the 12v battery is used even when the vehicle is switched off. If the vehicle isn’t driven often enough, this can drain the battery and prevent it from starting. We’d recommend a trickle charger or solar trickle charger to keep the battery topped up, if the vehicle is not being used regularly.

      Thanks

  2. have had several battery problems with my Toyota CH-R which (eventually) resulted in a new battery. I have recently returned from a 2 week holiday to find the battery flat again. When I rang the dealership I was advised this is a known issue on low mileage drivers on Toyota Hybrids and was sent an email advising me how to resolve this issue (namely leaving the car in ‘Ready’ mode for at least 60 minutes per week. How can I do this when I’m out of the country?) The salesman knew I did limited mileage when I purchased the car, yet didn’t advise me of this issue. Shame on you Toyota! Needless to say this will be the last Toyota I drive.

    1. Hi Derek,

      Sorry to hear that. If the vehicle is going to be stationary for an extended period of time, we’d recommend a 12V battery trickle charger, or a solar panel charger, to keep the battery charged. Ultimately, the car’s onboard systems do use the battery even when the vehicle is switched off, so the battery can go flat if it is not used regularly.

      Thanks

      1. Hi Steven,

        It really depends on the vehicle. Due to safety reasons, if you are not comfortable with setting up a trickle charger, we’d recommend contacting your nearest Toyota centre for assistance.

        Thanks

  3. But my dealer said they would not help, Quoting *I am unable to provide further technical advice on this matter, as Toyota do not make or supply any trickle chargers*

    1. Dealers are able to order a number of different trickle chargers:

      GBNGA-RNG01 1.5W 12V Solar Charger – up to 50Ah
      GBNGA-RNG02 2.4W 12V Solar Charger – up to 100Ah
