CAUTION
When attempting to free a stuck vehicle
If you choose to rock the vehicle back and forth to free it, make sure the sur-
rounding area is clear, to avoid striking other vehicles, objects or persons.
The vehicle may also lunge forward or lunge back suddenly as it becomes
free. Use extreme caution.
When shifting the shift lever (vehicles with a Multidrive)
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 and result in death or serious injury.
NOTICE
To avoid damaging the transmission and other components
Avoid spinning the wheels and do not rev the engine.
If the vehicle remains stuck after trying these procedures, the vehicle may
require towing to be freed.

If your vehicle has to be stopped in an emergency
Only in an emergency, such as if it becomes impossible to stop the
vehicle in the normal way, stop the vehicle using the following pro-
cedure:
Steadily step on the brake pedal with both feet and firmly
depress it.
Do not pump the brake pedal repeatedly as this will increase the
effort required to slow the vehicle.
Shift the shift lever to N.
If the shift lever is shifted to N.
After slowing down, stop the vehicle in a safe place by the
road.
Stop the engine.
If the shift lever cannot be shifted to N.
Keep depressing the brake pedal with both feet to reduce
vehicle speed as much as possible.
Vehicles without smart entry &
start system: Stop the engine
by turning the engine switch to
the ACC position.

CAUTION
If the engine has to be turned off while driving
Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
Vehicles without smart entry & start system: Never attempt to remove the
key, as doing so will lock the steering wheel.
Vehicles with smart entry &
start system: To stop the
engine, press and hold the
“ENGINE START STOP”
switch for 2 consecutive sec-
onds or more, or press it
briefly 3 times or more in suc-
cession.
Stop the vehicle in a safe place by the road.
Press and hold for 2 seconds or more,
or press briefly 3 times or more

iQ_WE_74014EEngine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Toyota rec-
ommends the use of approved “Toyota Genuine Motor Oil”. Another
motor oil of matching quality can also be used.
Oil grade:
0W-20, 5W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving”, SN
“Resource-Conserving” or ILSAC multigrade engine oil
15W-40 and 20W-50:
API grade SL, SM or SN multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Toyota vehicle at manufacturing,
and the best choice for good fuel
economy and good starting in
cold weather.
If SAE 0W-20 oil is not available,
SAE 5W-30 oil may be used.
However, it should be replaced
with SAE 0W-20 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 5W-30 or lower vis-
cosity engine oil is recom-
mended.
Temperature range anticipated before
next oil change.

The 0W portion of the oil viscosity rating 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 oil viscosity when the oil is at its operating
temperature. An oil with a higher viscosity 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 containers
to help you select the oil you should use.
API Service Symbol
Top portion: The oil quality desig-
nation by API (American Petro-
leum Institute) (SN)
Center portion: The SAE viscosity
grade (SAE 0W-20)
Lower portion: “Resource-Con-
serving” means that the oil has
fuel-saving and environmental
protection capabilities.
ILSAC Certification Mark
The ILSAC (International Lubri-
cant Standardization and
Approval Committee) Certification
Mark is displayed on the front of
the container.
