high speed sporty driving.
The multi-information display shows the di stribution of driving force between the
right and left rear wheels. (  P. 118)TVD (Torque Vectoring Differential) 
 : If equippedThe TVD system distributes driving force (torque) between the right and left
rear wheels automatically. This syst em contributes to enhanced steering
response while cornering and increased traction when exiting a corner, pro-
viding an agile driving experience.

RC F_U 6-1. Maintenance and care
●
Working from top to bott om, liberally apply water to the vehicle body, wheel
wells and underside of the vehicl e 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 wa sh soap and rins e 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 (if equipped)●
As the CFRP parts may change color if th ey 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. ■
Black stainless steel window moldings (vehicles with matte black painted wheels)
■
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 contains abrasives.
* : CFRP parts (if equipped) do not have a self-restoring coat.Cleaning and protect ing the vehicle exteriorPerform the following to protect the ve hicle and maintain it in prime condi-
tion:
The stainless steel window moldings are made
of black oxide coated stainless steel.
When cleaning the vehicle, do not scrub the
moldings with an abrasive cleaner as their finish
may be damaged or the color may change.

4136-3. Do-it-yourself maintenance
RC F_U 6
Maintenance and care Your vehicle is equipped with a tire pressure warning system that uses tire pres-
sure warning valves and transmitters to detect low tire inflation pressure before
serious problems arise. ●
If the tire pressure drops below a predet ermined level, the driver is warned by
a screen display and a warning light. (  P. 455, 477)●
The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. (  P. 103, 118)The illustration used is intended as an
example, and may differ from the image
that is actually disp layed on the multi-
information display.
◆ Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pr essure warning valv es and transmitters
must also be installed.
When new tire pressure wa rning valves and transmitters are installed, new ID
codes must be registered in the tire pressure warning computer and the tire
pressure warning system must be initia lized. Have tire pressure warning valve
and transmitter ID codes registered by your Lexus dealer. (  P. 414)
◆ Initializing the tire pressure warning system ■
The tire pressure warning system must be initialized in the following circum-
stances: ●
When rotating the tires. ●
When the tire inflation pressure is changed such as when changing travel-
ing speed. ●
When changing the tire size.
When the tire pressure warning system is initialized, the current tire inflation
pressure is set as the benchmark pressure.Tire pressure warning system

When trouble arises WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When towing the vehicle 
2WD models 
AWD modelsBe sure to transport the vehicle with all four
wheels raised off the ground. If the vehicle is
towed with the tires contacting the ground, the
drivetrain and related parts may be damaged
or an accident may occur due to a change in
direction of the vehicle.
Be sure to transport the vehicle with all four
wheels raised off the ground. If the vehicle is
towed with the tires contacting the ground, the
drivetrain or related parts may be damaged,

When steering wheel operations are heavier than usual, grip the steering wheel firmly
and operate it using more force than usual. ■
If the tire pressure warning light comes on
Be sure to observe the following precaution s. Failure to do so could cause a loss of
vehicle control and result in death or serious injury.
Vehicles with a spare tire ●
Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure
immediately. ●
If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire . Check the tires. If a tire is flat, change it
with the spare tire and have the flat tire repaired by the nearest Lexus dealer. ●
Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose
control of the steering wheel or the brakes. 
Vehicles with an emergency tire puncture repair kit ●
Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure
immediately. ●
If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you ha ve a flat tire. Check the tires. If a tire is flat, repair the
flat tire by using emergency tire puncture repair kit. ●
Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose
control of the steering wheel or the brakes. ■
If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
