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 parts 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 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:
●
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
automatic car wash.

■
Automatic car washes
●
Fold the mirrors before washing the vehicle. Start washing from the front of the vehicle.
Make sure to extend the 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 washable 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. (
■
Aluminum wheels
●
Remove any dirt immediately by using a neutral detergent.
●
Wash detergent off with water immediately after use.
●
To protect the paint from damage, make sure to observe the following precautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driving or park-
ing in hot weather
■
Brake
●
Brake caliper coating (GS350/GS300 with orange brake calipers for F SPORT mod-
els, and GS F)
• When using detergent, use neutral detergent.
Do not use hard brushes or abrasive cleaners, as they will damage the coating.
• Do not use detergent on the brake calipers when they are hot.
• Wash detergent off immediately after use.
●
GS F: Rust may form if the vehicle is parked with wet brake pads or disc rotors, causing
them to stick. Before parking the vehicle after it is washed, drive slowly and apply the
brakes several times to dry the parts.
■
Bumpers
Do not scrub with abrasive cleaners.
362
■
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, 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.
WARNING
■
When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may cause the
electrical components etc. to catch fire.
■
When cleaning the windshield (vehicles with rain-sensing windshield wipers)
●
When the upper part of the windshield where the raindrop sensor is located is
touched by hand
●
When a wet rag or similar is held close to the raindrop sensor
●
If something bumps against the windshield
●
If you directly touch the raindrop sensor body or if something bumps into the raindrop
sensor
■
Precautions regarding the exhaust pipes and rear bumper diffusers
Exhaust gases cause the exhaust pipes and rear bumper diffusers to become quite hot.
When washing the vehicle, be careful not to touch the pipes and rear bumper diffusers
until they have cooled sufficiently, as touching hot exhaust pipes and rear bumper dif-
fusers can cause burns.
■
Precaution regarding the rear bumper with Blind Spot Monitor (if equipped)
If the paint of the rear bumper is chipped or scratched, the system may malfunction. If
this occurs, consult your Lexus dealer.
Turn off AUTO mode of the wiper to prevent
the wiper from operating. (
If AUTO mode is selected, the wipers may
operate unexpectedly in the following situa-
tions, and may result in hands being caught or
other serious injuries and cause damage to the
wiper blades.

Application of coatings to the vehicle body (GS F)
Do not apply any kind of coating to the vehicle body as doing so may damage the paint
or reduce its durability.
■
To prevent paint deterioration and corrosion on the body and components (aluminum
wheels etc.)
●
Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar, pollen or tree sap is present on the paint surface

nectors or the following parts. The parts may be damaged if they come into contact
with high-pressure water.
• Traction related parts
• Suspension parts
• Steering parts
• Brake parts
●
GS F: Do not point the nozzle of a high pres-
sure washer at the areas shown in the illustra-
tion, as high pressure water may damage the
oil coolers.

sive sulfuric acid.
■
When working near the electric cooling fans or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant temperature is high.
