Cleaning and protecting the vehicle exterior
●Working from top to bottom, liberally apply water to the vehicle body, wheel
wells and underside of the vehicle to remove any dirt and dust.
● Wash the vehicle body using a sponge or soft cloth, such as a chamois.
● For hard-to-remove marks, use car wash soap and rinse thoroughly with
water.
● Wipe away any water.
● Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is cool.
■CFRP (Carbon Fiber Reinforced Plastic) part (GS F)
■Self-restoring coat *
The vehicle body has a self-restoring coating that is resistant to small surface scratches
caused in a car wash etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.
●The restoration time differs depending on the depth of the scratch and outside tem-
perature. The restoration time may become shorter when the coating is warmed by
applying warm water.
●Deep scratches caused by keys, coins, etc. cannot be restored.
●Do not use wax that contain abrasives.
* : CFRP parts (GS F) do not have a self-restoring coat.
Perform the following to protect the vehicle and maintain it in prime condi-
tion:
CFRP is used for the parts shown in the illustra-
tion.
●As the CFRP parts may change color if they
are exposed to ultraviolet rays for extended
periods of time, Lexus recommends that your
vehicle be stored in a place where it will not
be exposed to direct sunlight.
●Do not use wax that contains abrasives.
●CFRP parts may get scratched when using an
