Rear sunshade∗
■Reverse operation feature
This function will become operational after the vehicle has been driven at 9 mph (15
km/h) or more with the rear sunshade in the raised position.
To ensure adequate rear visibility, the sunshade automatically lowers when the shift
lever is shifted to R and the function is in an operational condition.
However, the rear sunshade is raised again if either of the following occurs:
●The switch is pressed again.
●The shift lever is shifted out of R, and the vehicle reaches a speed of 9 mph (15
km/h).
If the engine is turned off when the rear sunshade has been lowered due to the
reverse operation feature, it will not be raised even when the engine is turned on
again and the vehicle reaches a speed of 9 mph (15 km/h). To raise the sunshade
again, press the switch.
■The rear sunshade can be used when
The “ENGINE START STOP” switch is in IGNITION ON mode.
The rear sunshade can be raised and lowered by operating the switch
shown below.

Floor mat
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.
The shape of the retaining hooks
(clips) and the fixing procedure
of the floor mat for your vehicle
may differ from those shown in
the illustration. 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 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 (automatic transmission) or N (manual
transmission), fully depress each pedal to
