2013 TOYOTA COROLLA engine overheat

194 2-5. Driving information
●Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temper atures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immediately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
(  P. 461)
● Always place wheel blocks under both the vehicle’s and the
trailer’s wheels when parking. Ap ply the parking brake firmly, and
put the transmission in P (automatic transmission) or in 1 or R
(manual transmission). Avoid park ing on a slope, but if unavoid-
able, do so only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blo cks under both the vehicle’s
and trailer’s wheels.
When the wheel blocks are in place, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into 1 or R (manual transmission) or P (automatic trans-
mission) and turn off the engine.
● When restarting after parking on a slope:
With the transmission in P (automatic transmission) or the
clutch pedal (manual transmission) depressed, start the
engine. On vehicles with an au tomatic transmission, be sure
to keep the brake pedal depressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake (and also the brake pedal on vehi-
cles with an automatic transmission), and slowly pull or back
away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.

NOTICE
■To prevent damage to the vehicle
Do not pull- or push-start the vehicle, because the catalytic converter may
overheat and become a fire hazard.
■ When handling jumper cables
Be careful that the jumper cables do not become tangled in the cooling fans
or any of the belts when connecting or disconnecting them.
■ When attaching the engine cover (1.8 L 4-cylinder [2ZR-FE] engine)
Ensure that the rubber grommets remain attached to the engine cover. If the

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.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 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.
