COROLLA iM_U (OM12M42U)
●The engine coolant temperature gauge ( →P. 74) enters the red
zone or a loss of power is exper ienced (for example, the vehicle
speed does not increase).
● Steam comes out from under the hood.
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 sufficient ly, inspect the
hoses and radiator core (radia-
tor) for any leaks.

If a large amount of coolant
leaks, immediately contact your
Toyota dealer.
If your vehicle overheats
The following may indicate that your vehicle is overheating.

The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir.Reservoir
“FULL”
“LOW”
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is unavail-
able.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fan opera tes and to check for coolant leaks
from the radiator or hoses.
The fan operates when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fan is operating by checking the fan
sound and air flow. If it is difficult to check these, turn the air conditioning
system on and off repeatedly.
(The fan may not operate in freezing temperatures.)
If the fan is not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fan is operating:
Have the vehicle in spected at the nearest Toyota dealer.

WARNING
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
● 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.
● Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
High temperature steam or coolant could spray out.
NOTICE
■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.
■ To prevent damage to the cooling system
Observe the following precautions:
● Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).
● Do not use any coolant additives.

When trouble arises
COROLLA iM_U (OM12M42U)
Stop the engine. Shift the shift lever to P (continuously variable
transmission) or N (manual transmission), and set the parking
brake.
Remove the mud, snow or sand from around the front wheels.
Place wood, stones or some othe r material under the front wheels
to help provide traction.
Restart the engine.
Shift the shift lever to D or R (cont inuously variable transmission) or
1 or R (manual transmission) and release the parking brake. Then,
while exercising caution, depress the accelerator pedal.
■ When it is difficult to free the vehicle
If the vehicle becomes stuck
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
Press to turn off TRAC.

Engine oil selection
“Toyota Genuine Motor Oil” is us
ed in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-20 is not available, SAE
5W-20 oil may be used. However,
it must be replaced with SAE 0W-
20 at the next oil change.
Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows cold startability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, \
or
under extreme load conditions.
How to read oil container label:
The International Lubricant Sp ecification Advisory Committee
(ILSAC) Certification Mark is ad ded to some oil containers to help
you select the oi l you should use.
