Rear window and outside rear view mirror
defoggers
On/off
The defoggers will automatically
turn off after 15 to 60 minutes. The
operation time changes according
to the ambient temperature and
vehicle speed.
Operating conditions
The power switch must be in the ON mode.
These features are used to defog the rear window, and to remove
raindrops, dew and frost from the outside rear view mirrors.
CAUTION
When the outside rear view mirror defoggers are on
Do not touch the rear view mirror surfaces, as they can become very hot
and burn you.
NOTICE
To prevent 12-volt battery discharge
Turn the defoggers off when the hybrid system is off.

Notes for a smart entry & start system
If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the
following correction procedures to wash the vehicle:
Place the key in a position 2 m (6 ft.) or more separate from the vehicle
while the vehicle is being washed. (Take care to ensure that the key is not
stolen.)
Set the electronic key to battery-saving mode to disable the smart entry &
start system. (P. 1 4 9 )
Aluminum wheels
Remove any dirt immediately by using a neutral detergent. Do not use hard
brushes or abrasive cleaners. Do not use strong or harsh chemical cleaners.
Use the same mild detergent and wax as used on the paint.
Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
Wash detergent from the wheels immediately after use.
Bumpers
Do not scrub with abrasive cleaners.
Front side windows water-repellent coating
The following precautions can extend the effectiveness of the water-repel-
lent coating.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accumulate on the windows for a long
period.
Clean the windows with a soft, damp cloth as soon as possible.
• Do not use wax or glass cleaners that contain abrasives when cleaning
the windows.
• Do not use any metallic objects to remove condensation build up.
When the water-repellent performance has become insufficient, the coating
can be repaired. Contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
Outside rear view mirror rain-clearing coating (if equipped)
Observe the following precautions in order to retain the rain-clearing proper-
ties of the mirrors:
Clean the mirrors using a car shampoo or glass cleaner that does not contain
silicone or an abrasive compound, and rinse thoroughly with water.
Allow the mirrors to be exposed to direct sunlight for 1 to 2 days.
