5-2. Steps to take in an emergency
If the vehicle becomes stuck
■When changing the shift position
Depress the brake pedal and ensure that t
he vehicle has stopped completely
before changing the shift position. Failure to do so could cause the rejection func -
tion to be activated, canceling the shift position change, or causing the shift position
to change to N automatically.
CAUTION
■When attempting to free a stuck vehicle
If you choose to rock the vehicle back and forth to free it, make sure the surround-
ing area is clear to avoid striking other vehicles, objects or people. The vehicle may
also lunge forward or lunge back sudden ly as it becomes free. Use extreme cau-
tion.
■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.
Carry out the following procedures if the tires spin or the vehicle becomes
stuck in mud, dirt or snow:
Apply the parking brak e, change the shift position to P and
stop the hybrid system.
Remove the mud, snow or sand from around the stuck tire.
Place wood, stones or some othe r material under the tir
es to
help provide traction.
Restart the hybrid system.
Make sure to change the shift position to D or R, r
elease the
parking brake, and then care fully depr
ess the accelerator
pedal.
Turn off the TRAC and VSC systems if these functions are hamper -
ing your attempts to free the vehicle. (  P. 2 2 6 )

Vehicle specifications
■Engine oil selection
“Toyota Genuine Motor Oil” is used in y
our Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the follow-
ing 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
star

ting in cold weather.
If SAE 0W-20 is not available,
S
AE 5W-20 oil may be used.
However, 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 wi th 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
temper
ature. 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 label:
The ILSAC (International Lubricant St andar
dization and Approval Com-
mittee) Certification Mark is added to some oil containers to help y
ou
select the oil you should use.
