When trouble arises
QWhen recharging or replacing the battery (vehicles with smart entry &
start system)
O 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.
O 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.
O 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.
O Vehicles with Stop & Start system: After the battery terminals have been dis-
connected and reconnected or, the battery has been replaced, the Stop &
Start system may not automatically stop the engine for up to an hour.
Q When replacing the battery
O Use a battery that conforms to European regulations.
O Use a battery with the same case size as the previous battery and an equiv-
alent 20 hour rate capacity (20HR) 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.
O Vehicles with Stop & Start system: Use a genuine battery specifically
designed for use with the Stop & Start system or a battery with equivalent
specifications to a genuine battery. If an unsupported battery is used, Stop &
Start system functions may be restricted to protect the battery.
Also, battery performance may decrease and the engine may not be able to
restart. Contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer for details.
O For details, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

WARNING
QWhen removing the battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal con-
tacts any metal in the surrounding area when the positive (+) terminal is
removed, a spark may occur, leading to a fire in addition to electrical shocks
and death or serious injury.
Q Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery:
O Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.
O 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.
O Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
O Do not smoke, use matches, cigarette lighters or allow open flame near
the battery.
Q 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:
O 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.
O Do not lean over the battery.
O 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.
O Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
O Do not allow children near the battery.

When trouble arises
WARNING
QWhen exchanging the battery
O When the vent plug and indicator are close to the hold down bracket, the
battery fluid (sulfuric acid) may leak.
O For information regarding battery replacement, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
Q To prevent damage to the vehicle (vehicles with manual transmission)
Do not pull- or push-start the vehicle as the three-way catalytic converter or
catalytic converter may overheat and become a fire hazard.
NOTICE
Q When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fan or belt.

If your vehicle overheats
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled down sufficiently, inspect the hoses and
radiator core (radiator) for any leaks.
Radiator
Cooling fan
If a large amount of coolant
leaks, immediately contact any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
The following may indicate that your vehicle is overheating.
O The needle of the engine coolant temperature gauge (P. 130)
enters the red zone or a loss of engine power is experienced.
(For example, the vehicle speed does not increase.)
O Vehicles with multi-information display: “Engine Coolant Temp
High Stop in a Safe Place See Owner’s Manual” is shown on the
multi-information display.
O Steam comes out from under the hood.

When trouble arises
Start the engine to check that the radiator cooling fan operates and
to check for coolant leaks from the radiator or hoses.
If the fan is not operating:
Stop the engine immediately and contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
If the fan is operating:
Have the vehicle inspected at the nearest authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
WARNING
Q When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
O If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot.
O Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fans and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
O Do not loosen the radiator cap (if equipped), the engine coolant reservoir
cap or intercooler coolant reservoir cap (if equipped) while the engine and
radiator are hot. High temperature steam or coolant could spray out.
NOTICE
Q When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
Q To prevent damage to the cooling system
Observe the following precautions:
O Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
O Do not use any coolant additive.
