Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
Avoiding a discharged battery
Turn off the headlights and the air conditioning system while the engine is
off.
Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
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 (vehicles with a smart
entry & start system)
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.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the engine starts, have the vehicle checked at any autho-
rized Toyota dealer or repairer, or another duly qualified and
equipped professional as soon as possible.STEP 5

If your vehicle overheats
If your engine overheats:
Stop the vehicle in a safe place and turn off the air condi-
tioning system.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam sub-
sides and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the temperature of the engine (shown on the
instrument cluster) begins to fall and then stop the engine.
If the fan is not operating:
Stop the engine and call any authorized Toyota dealer or
repairer, or another duly qualified and equipped profes-
sional.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radi-
ator) for any leaks.STEP 1

Overheating
If you observe the following, your vehicle may be overheating.
The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
Steam is coming from under the hood.
CAUTION
To prevent an accident or injury when inspecting under the hood of
your vehicle
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, caus-
ing serious injury such as burns.
Keep hands and clothing away from the fan and other belts while the
engine is running.
Do not loosen the radiator cap while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable. (P. 429)
Have the vehicle checked at the nearest authorized Toyota dealer
or repairer, or another duly qualified and equipped professional as
soon as possible.
