When trouble arises
If the vehicle battery is discharged
If you have a set of jumper (or booster) cables and a second vehicle
with a 12-volt battery, you can jump start your vehicle by following the
steps below.
Open the hood. ( P. 256)
Connect the jumper cables according to the following procedure:
Connect a positive jumper cable clamp to the positive (+) battery
terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the
positive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery termi-
nal on the second vehicle.
Connect the clamp at the other end of the negative cable to a
solid, stationary, unpainted metallic point away from the battery
and any moving parts, as shown in the illustration.
The following procedures may be used to start the engine if the
vehicle’s battery is discharged.
You can also call any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.

Start the engine of the second vehicle. Increase the engine speed
slightly and maintain it at that level for approximately 5 minutes to
recharge the battery of your vehicle.
Open and close any of the doors of your vehicle with the engine
switch off.
Maintain the engine speed of the second vehicle and turn the
engine switch to IGNITION ON mode, then start the vehicle’s
engine.
Once the vehicle’s engine has started, remove the jumper cables in
the exact reverse order from which they were connected.
Once the engine starts, have the vehicle inspected at any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer
as soon as possible.
■ To prevent battery discharge
● Turn off the headlights and the audio system while the engine is stopped.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ 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.)
■ Precautions when the battery is discharged
● In some cases, it may not be possible to unlock the doors using the smart
entry & start 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 trouble arises
■When replacing the battery
● Use a battery that conforms to European regulations.
● Use a battery that the case size is same as the previous one (LN2), 20 hour
rate capacity (20HR) is equivalent (60Ah) or greater, and performance rating
(CCA) is equivalent (356A) 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 vehicle
is not used is a short time, the battery may discharge and the engine may
not be able to start.
● For details, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer
WARNING
■ Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery:
● Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with anything other than the intended ter-
minal.
● Do not allow the other end of the jumper cable connected to the “+” termi-
nal to come into contact with any other parts or metal surfaces in the area,
such as brackets or unpainted metal.
● Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
● Do not smoke, use matches, cigarette lighters or allow open flame near
the battery.

WARNING
■Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery:
● When working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, clothing
or the vehicle body.
● Do not lean over the battery.
● In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
● Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
● Do not allow children near the battery.
■ To prevent damage to the vehicle
Do not pull- or push-start the vehicle as the three-way catalytic converter
may overheat and become a fire hazard.
NOTICE
■ When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fans or engine drive belt.
