4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
■Automatic car washes
●Fold the mirrors back before washing the vehicle.
●Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
■High pressure automatic car washes
Do not allow the nozzles of the car wash to come within close proximity of the win-
dows. Before entering an automatic car wash, check that the fuel filler door on your
vehicle is closed properly.
■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.
■Bumpers and side moldings
Do not scrub with abrasive cleaners.
Perform the following to protect the vehicle and maintain it in prime condi-
tion.
● Working from top to bottom, liber ally 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 thor-
oughly 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.

Turning directional tiresTire direction marks
The tires listed below are direc-
tional. The tire sidewalls are
marked with arrows indicating the
rolling direction of the tire. If
mounted on the wrong side of the
vehicle, directional tires will per-
form poorly.
Installing tire inflation pressure sensors
When replacing tires or wheels, ti re pressure sensors must also be
installed. Tire pressure sensors ca n be installed in any of the following
three ways:
● Sensors can be removed from the ol d wheels and installed on the new
wheels.
■ The tire pressure warning system
Your Lexus is equipped with a tire pressure warning system that uses
tire pressure sensors to detect low tire pressure before serious
problems arise. ( P. 335, 339)
Before removing the tire from th e wheel, remove the system’s tire
inflation pressure sensor. Be carefu l not to damage the sensor when
removing and installing the tires.

Maintenance and care
●When replacing only the tire, the sensor already installed on the wheel
does not need to be replaced.
● Replacing both a wheel and its sensor.
When new tire pressure sensors are installed, new sensor ID codes must be
registered in the ECU and tire inflatio n pressure sensor must be initialized.
( P. 2 8 1 , 2 8 2 )
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the following
circumstances:
●When the standard tire pressure changes by replacing tires or
wheels
● When tires are rotated.
● When tire pressure sensors are replaced.
● When driving with the tires inflated to a higher than standard tire
pressure.
When the tire pressure warning sy stem is initialized, the current tire
pressure is set as the pressure benchmark.
■ How to initialize the tire pressure warning system
To initialize the system, use the satellite switch. ( P. 218)
Park the vehicle in safe place and turn off the engine.
Adjust the tire pressure to the specified pressure ( P. 383)
Start the engine.
Make sure to adjust the tire pressure to the specified level. The tire infla-
tion pressure warning system will operate based on this pressure level.

The tire pressure initialization
setting display
Continue to press the  or 
switch until the initialization setting
display appears.
It may take several minutes to com-
plete the setting. Wait for several
minutes before turning the engine
switch OFF if necessary.
Recording tire pressure settings
Press the ON/OFF button for
more than 3 seconds. At this time,
the tire inflation pressure warning
indicator flashes 3 times and the
message showing that the initial
setting is complete is displayed on
the multi-information display.
Registering and selecting tire inflation pressure sensor ID codesThe tire inflation pressure sensor is equipped with a unique ID code.
To select tire inflation pressure sensor ID codes, use the satellite switch.
( P. 218)
■ Registering ID codes
Two separate sets of ID codes can be registered for each vehicle. This
allows 2 separate sets of settings to be conveniently recorded for all
season and winter tires.
MAIN: The MAIN ID code is used fo r the factory installed tire pres-
sure sensors.
2nd: The 2nd ID code is used for tire inflation pressure sensors associ-
ated with a secondary set of tires.
Make sure to have all tire inflation pressure warning system ID codes regis-
tered by your Lexus dealer. ID codes must be reset when tires or wheels are
replaced.
