Maintenance and care
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:
●If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
●Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.
■After recharging/reconnecting the battery (vehicles with a smart key sys-
tem)
●Unlocking the doors using the smart key system may not be possible imme-
diately after reconnecting the battery. If this happens, use the wireless
remote control or the mechanical key to lock/unlock the doors.
●Start the engine with the engine switch in ACCESSORY mode. The engine
may not start with the engine switch turned off. However, the engine will
operate normally from the second attempt.
●The engine switch mode is recorded by the vehicle. If the battery is recon-
nected, the vehicle will return the engine switch mode to the status it was in
before the battery was disconnected. Make sure to turn off the engine
before disconnecting the battery. Take extra care when connecting the bat-
tery if the engine switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
WARNING
■Chemicals in the battery
Batteries contain poisonous and corrosive sulfuric acid and may produce
hydrogen gas which is flammable and explosive. To reduce the risk of death
or serious injury, take the following precautions while working on or near the
battery:
●Do not cause sparks by touching the battery terminals with tools.
●Do not smoke or light a match near the battery.
●Avoid contact with eyes, skin and clothes.
●Never inhale or swallow electrolyte.
●Wear protective safety glasses when working near the battery.
●Keep children away from the battery.

Maintenance and care
WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident
resulting in death or serious injury.
●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
■When initializing the tire pressure warning system
Do not initialize the tire pressure warning system without first adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pres-
sure warning light may not come on even if the tire inflation pressure is
low, or it may come on when the tire inflation pressure is actually nor-
mal.

dealer as soon as possible.
■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■To prevent battery discharge
●Turn off the headlights and the audio system while the engine is off.
●Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■When the battery is removed or discharged
●Information stored in the ECU is cleared. When the battery is depleted, have
the vehicle inspected at your Toyota dealer.
●Some systems may require initialization. (→P. 575)
■When removing the battery terminals
When the battery terminals are removed, the information stored in the ECU is
cleared. Before removing the battery terminals, contact your Toyota dealer.
■Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)

CAMRY_U (01999-06122)■When recharging or replacing the battery (vehicles with a smart key sys-
tem)
●In some cases, it may not be possible to unlock the doors using the smart
key system when the battery is discharged. Use the wireless remote control
or the mechanical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has recharged
but will start normally after the second attempt. This is not a malfunction.
●The engine switch mode is memorized by the vehicle. When the battery is
reconnected, the system will return to the mode it was in before the battery
was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.
■When exchanging the battery
●Use a battery that conforms to European regulations.
●Use a battery that the case size is same as the previous one (LN3), 20 hour
rate capacity (20HR) is equivalent (70Ah) or greater, and performance rating
(CCA) is equivalent (600A) or greater.
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi-
cle is not used is a short time, the battery may discharge and the engine
may not be able to start.
●For details, consult your Toyota dealer.
