4RUNNER (U)_(OM35B23U)
●The needle of the engine coolant temperature gauge (P. 8 1 )
enters the red zone or a loss of engine power is experienced.
(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 sufficiently, inspect the
hoses and radiator core (radia-
tor) for any leaks.
Radiator
Cooling fan
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
The coolant level is satisfactory
if it is between the “F” and “L”
lines on the reservoir.

Add engine coolant if neces-
sary. (P. 351)
Water can be used in an emer-
gency if engine coolant is unavail-
able.
Start the engine to check that the radiator cooling fan operate and
to check for coolant leaks from the radiator or hoses.
If the fan are not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fan are operating:
Have the vehicle inspected at the nearest Toyota dealer.

CAUTION
■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 fans and belts.

●Do not loosen the radiator cap and the
coolant reservoir cap while the engine
and radiator are hot.
High temperature steam or coolant
could spray out.

NOTICE
■When adding engine coolant
Wait until the engine has cooled down before adding engine coolant.
When adding coolant, do so slowly. 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
4RUNNER (U)_(OM35B23U)
Stop the engine. Set the parking brake and shift the shift lever to P.
Remove the mud, snow or sand from around the stuck tire.
Place wood, stones or some other material under the tires to help
provide traction.
Restart the engine.
Shift the shift lever to D or R position and carefully apply the accel-
erator to free the vehicle.
Turn off TRAC and VSC if these functions are hampering your attempts to
free the vehicle. (P. 261)
If the vehicle becomes stuck
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
CAUTION
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the
surrounding area is clear to avoid striking other vehicles, objects or people.
The vehicle may also lunge forward 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 transmission and other components
●Avoid spinning the wheels and depressing the accelerator pedal more
than necessary.
●If the vehicle remains stuck even after these procedures are performed,
the vehicle may require towing to be freed.
●When a warning message for the automatic transmission fluid temperature
is displayed while attempting to free a stuck vehicle, immediately remove
your foot from the accelerator pedal and wait until the warning message
disappears. Otherwise, the transmission may become damaged.

the engine oil. Warm up and turn off the engine, wait more than 5 minutes,

Engine oil selection
Except for Puerto Rico
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to sat-
isfy 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 starting 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 Specification Advisory Committee (ILSAC)
Certification Mark is added to some oil containers to help you select
the oil you should use.
For Puerto Rico
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade:
0W-20, 5W-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):
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-20, 5W-20
or 5W-30 engine oil is recom-
mended.
