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 vehi cle 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 a smart key
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 a smart key system: Never attempt to remove the key, as
doing so will lock the steering wheel.
Vehicles with a smart key sys-
tem: To stop the engine, press
and hold the “ENGINE START
STOP” switch for 2 consecu-
tive seconds or more, or press
it briefly 3 times or more in
succession.
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

Lubrication system
*: The engine oil capacity is a reference quantity to be used when changing theengine oil. Warm up and turn off the engine, wait more than 5 minutes, and
check the oil level on the dipstick.
■ Engine oil selection
“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:
1AR-FE engine
ILSAC multigrade engine oil
2GR-FE engine
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.

Vehicle specifications
SIENNA_OM_OM45472U_(U)
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 ILSAC (International Lubric ant Standardization and Approval
Committee) Certification Mark is added to some oil containers to help
you select the oil you should use.
