●Do not allow the nozzles of the car wash to come within close proximity of the
windows.
●Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.

Maintenance and care
■When using a car wash
If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. Place the key in a position 6 ft. (2
m) or more separate from the vehicle while the vehicle is being washed. (Take care
to ensure that the key is not stolen.)
■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.
■Bumpers and side moldings
Do not scrub with abrasive cleaners.
■Side windows water-repellent coating
●The following precautions can extend the effectiveness of the water-repellent
coating.
• Remove any dirt, etc. from the 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 your Lexus dealer.
■Outside rear view mirror rain -clearing coating (if equipped)
Observe the following precautions in order to retain the rain-clearing properties 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.
