If the vehicle becomes stuck
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
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.

becomes stuck in mud, dirt, or snow.
Stop the hybrid system. Set t he parking brake and push the
“P” position switch.

Lubrication system■ Engine oil selection
“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 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 may be used. How-
ever, it must be replaced with
SAE 0W-20 at the 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 vehi-
cle is operated at high speeds, or under extreme load conditions.
