ing for about 3 minutes after the engine switch is turned to the “LOCK” posi-
tion.
With the engine switch in the “ON” position, the electric cooling fans may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. Be sure the engine switch is in the “LOCK” position when
working near the electric cooling fan or radiator grille.
Vehicles with smart key system: The electric cooling fan may keep rotating
for about 3 minutes even after the “ENGINE START STOP” switch is OFF.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fans may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. Be sure the “ENGINE START STOP” switch
is OFF when working near the electric cooling fans or radiator grille.

5-2. Steps to take in an emergency
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
subsides 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 fans are operating.
If the fans are operating: Wait until the temperature of the engine (shown on the
instrument cluster) begins to fall and then stop the
engine.
If the fans are not operating: Stop the engine and call your Toyota dealer.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radi-
ator) for any leaks.
If the engine compartment
cover needs to be removed.

■
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 comes 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 coolant reservoir 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. 626)
Have the vehicle chec ked at the nearest Toyota dealer as soon as
possible.
