Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering with the ped-
als while driving. An unexpect edly high speed may result or it may become difficult to
stop the vehicle. This could lead to an ac cident, resulting in death or serious injury.■
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 ●
Check that the floor mat is securely fixed in
the correct place with all the provided retain-
ing hooks (clips). Be especially careful to per-
form this check after cleaning the floor. ●
With the hybrid system stopped and the shift
lever in P, fully depress each pedal to the floor
to make sure it does not interfere with the
floor mat.

Observe the following precautions.
Failure to do so may result in death or serious injury.●
Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle. ●
Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the effec-
tiveness of the seat be lt and head restraint.●
Do not place anything under the front seats.
Objects placed under the front seats may be come jammed in the seat tracks and stop
the seat from locking in place. This may lead to an accident and the adjustment mech-
anism may also be damaged. ●
When driving over long distances, take regular breaks before you start to feel tired.
Also, if you feel tired or sleepy while drivin g, do not force yourself to continue driving
and take a break immediately.

the instructions regardin g seat belt usage. ( P. 3 2 )■

collision, but will not activate for th e second or subsequent collisions.■
