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.

Maintenance and care
NOTICE
■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
• If dead insects, insect droppings or bird droppings are present on the paint surface
• After driving in an area contaminated wi th soot, oily smoke, mine dust, iron pow-
der or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gaso line are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corroding, remo ve any dirt and store in a place with low
humidity when storing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic substances or scrub with a hard brush.
This may damage the su rfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■When using an automatic car wash (vehicle s with rain-sensing windshield wipers)
Turn off AUTO mode of the wiper to prevent the wiper from operating. (P. 222)
If AUTO mode is selected, the wipers may operate and the wiper blades may be dam-
aged.
■When using a high-pressure car wash
●When washing the vehicle, do not let water from the high-pressure washer directly hit
the camera or the area around the camera. Due to the shock from high-pressure
water, it is possible that the device may not operate normally.
●Do not bring the nozzle tip close to boots (rubber or resin manufactured cover), con-
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.

5638-1. Specifications

Vehicle specifications
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing the tire’s
resistance to the generation of heat and its ability to dissipate heat when
tested under controlled conditions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to sudden tire failure.
Grade C corresponds to a level of perfor mance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is properly inflated and
not overloaded.
Excessive speed, underinflation, or excessiv e loading, either separately or in com-
bination, can cause heat buildup and possible tire failure.
