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)
CFRP is used for the part
s shown in the illustration.
■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 temper-
ature. The restoration time may become shor ter when the coating is warmed by apply-
ing 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 ve hicle and maintain it in prime condi-
tion:
●As the CFRP parts may change color if they
are exposed to ultraviolet rays for extended
periods of time, Lexu s 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
automatic car wash.

Maintenance and care
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of the vehicle.
Make sure to extend th e mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface and harm your
vehicle’s paint.
●Rear spoiler (if equipped) may not be wash able in some automatic car washes. There
may also be an increased risk of damage to vehicle.
■High-pressure car washes
●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 prop-
erly.
■Notes for a smart access system with push-button start
If the door handle becomes wet while the electronic key is within the effective range, the
door may lock and unlock repeatedly. In that case, follow the following correction proce-
dures to wash the vehicle:
●Place the key in a position 6 ft. (2 m) or more separate from the vehicle while the vehi-
cle 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 access system with
push-button start. ( P. 1 5 2 )
■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.
■Brake caliper coating (GS350/GS200t with orange brake calipers for F SPORT
models, and GS F)
●When using detergent, use neutral detergent.
Do not use hard brushes or abrasive cl eaners, as they will damage the coating.
●Do not use detergent on the brake calipers when they are hot.
●Wash detergent off immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent coating (if equipped)
●The following precautions can extend the effectiveness of the water-repellent 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, da mp cloth as soon as possible.
• Do not use wax or glass cleaners that co ntain 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.

●Start the engine with the engine switch in ACCESSORY mode. The engine may not
start with the engine switch turned off. However, the engine will operate normally from
the second attempt.
