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.

Vehicle specifications
4RUNNER (U)_(OM35B23U)
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 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-20”
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.
