7-2. Steps to take in an emergency
When trouble arises
engine coolant is unavailable.
6Start the engine and turn the air
conditioning system on to check
that the radiator cooling fan
operate and to check for coolant
leaks from the radiator or hoses.
The fan operate when the air condition-
ing system is turned on immediately 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.)
7 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 (espe-cially 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 caps 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 additive.

striking other vehicles, objects or peo- ple. The vehicle may also lunge for-ward or lunge back suddenly as it
becomes free. Use extreme caution.
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.This may lead to unexpected rapid
acceleration of the vehicle that may cause an accident resulting in death or serious injury.
NOTICE
■To avoid damaging the transmis-sion and other components
●Avoid spinning the front wheels and depressing the accelerator pedal more than necessary.
●If the vehicle remains stuck even
after these procedures are per- formed, the vehicle may require towing to be freed.

Temperature range anticipated
before 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 tempera-
ture.
How to read oil container labels:
Either or both API registered marks are added to some oil containers to
help you select the oil you should
use.
API Service Symbol
Top portion: “API SERVICE SP” means
the oil quality designation by American
Petroleum Institute (API).
Center portion: “SAE 0W-20” means
the SAE viscosity grade.
Lower portion: “Resource-Conserving”

98 or higher for optimum
engine performance.
If this premium type cannot be
obtained, you may temporarily
use unleaded gasoline with a
Research Octane Number as
low as 95. The use of such gas-
oline may cause the engine to
knock or drastically reduce
output to protect itself while
driving with a heavy load. To
avoid this refill the tank with
premium unleaded gasoline as
soon as possible.

■During customization
As the engine needs to be running
during customization, ensure that the vehicle is parked in a place with ade-quate ventilation. In a closed area
such as a garage, exhaust gases including harmful carbon monoxide (CO) may collect and enter the vehi-
cle. This may lead to death or a seri- ous health hazard.
NOTICE
■During customization
To prevent battery discharge, ensure that the engine is running while cus-
tomizing features.
