CAUTION
Observe the following precautions.
Failure to do so may cause the driver's floor mat to slip, possibly interfering with the
pedals while driving. An unexpectedly high speed may result or it may become diffi-
cult to stop the vehicle, leading to a serious accident.
■When installing the driver's floor mat
●Do not use floor mats designed for other models or different model year vehicles,
even if they are Lexus Genuine floor mats.
●Only use floor mats designed for the driver's seat.
●Always install the floor mat securely using the retaining hooks (clips) provided.
●Do not use two or more floor mats on top of each other.
●Do not place the floor mat bottom-side up or upside-down.
■Before driving
Use only floor mats designed specifically for vehicles of the same model
and model year as your vehicle. Fix them securely in place onto the carpet.
Fix the floor mat in place using
the retaining hooks (clips) pro-
vided.
For details, refer to the floor mat
retention clip installation
instructions supplied with the
clips.
●Check that the floor mat is securely fixed in
the right place with all the provided retain-
ing hooks (clips). Be especially careful to
perform this check after cleaning the floor.
●With the engine stopped and the shift lever
in P (automatic transmission) or N (manual
transmission), fully depress each pedal to
the floor to make sure it does not interfere
with the floor mat.

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 surround-
ing 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
With automatic transmission vehicles, 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.
Carry out the following procedures if the tires spin or the vehicle becomes
stuck in mud, dirt, or snow.
Stop the engine. Set the parking brake and shift the shift lever
to P (vehicles with an automatic transmission) or N (vehicles
with a manual transmission).
Remove the mud, snow, or sand from around the stuck tire.
Place wood, stones or some other material to help provide
traction under the tires.
Restart the engine.
Shift the shift lever to the D or R position (vehicles with an auto-
matic transmission) or 1 or R position (vehicles with a manual
transmission), release the parking brake and carefully apply
the accelerator to free the vehicle.
Turn off TRAC and VSC if these functions are hampering your
attempts to free the vehicle. ( P. 1 9 8 )
