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.
