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.

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.
