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 an accident, or leading to death or a 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
retaining hooks (clips). Be especially care-
ful to perform this check after cleaning the
floor.
●With the engine stopped and the shift lever
in P, fully depress each pedal to the floor to
make sure it does not interfere with the
