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 any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
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 radiator 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.

If the vehicle becomes stuck
Stop the engine. Set the parking brake and shift the shift lever to N.
Remove the mud, snow or sand from around the stuck tire.
Place wood, stones or some other material to help provide traction
under the tires.
Restart the engine.
Shift the shift lever to E, M or R (multi-mode manual 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
Press to turn off TRC.
Turn off TRC and/or VSC if these functions are hampering your attempts to
free the vehicle. ( P. 248)
■ Emergency hooks
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
When your vehicle becomes stuck and
cannot move, the emergency hooks are
used for another vehicle to pull your
vehicle to pull your vehicle out in an
emergency.
Your vehicle is not designed to tow
another vehicle.

■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Toyota
recommends the use of approved “Toyota Genuine Motor Oil”.
Another motor oil of matching quality can also be used.
Oil grade:
0W-16:
API grade SN “Resource-Conserving” multigrade engine oil
0W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving” or SN
“Resource-Conserving”; or ILSAC multigrade engine oil
15W-40:
API grade SL, SM or SN multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-16 is filled into your
Toyota vehicle at manufactur-
ing, and the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-16 oil is not avail-
able, SAE 0W-20 oil may be
used. However, it should be
replaced with SAE 0W-16 at the
next oil change.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures,
the engine may become difficult
to start, so SAE 0W-16, 0W-20
or 5W-30 engine oil is recom-
mended.

before next oil change

Oil viscosity (0W-16 is explained here as an example):
• The 0W in 0W-16 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 16 in 0W-16 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 labels:
Either or both API registered marks are added to some oil contain-
ers to help you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designa-
tion by American Petroleum
Institute (API).
Center portion: “SAE 0W-16”
means the SAE viscosity grade.
Lower portion: “Resource-Con-
serving” means that the oil has
fuel-saving and environmental
protection capabilities.
ILSAC Certification Mark
The International Lubricant Specification Advisory Committee (ILSAC)
Certification Mark is displayed on the front of the container.

● Consult any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer.
● You may occasionally notice light knocking for a short time while accelerat-
ing or driving uphill. This is normal and there is no need for concern.
When you find these types of fuel label at the gas station, use
only the fuel with one of the following labels.

EU area:
You must only use unleaded gasoline conforming to European
standard EN228.
Select unleaded gasoline with a Research Octane Number of 95
or higher for optimum engine performance.
