nChanging the settings
Each item is displayed and its setting can be changed only in the following condi-
tions:
lIntuitive parking assist: When the “ENGINE START STOP” switch is in IGNI-
TION ON mode.
lItems other than the above: When the “ENGINE START STOP” switch is in
IGNITION ON mode and the vehicle is stopped.
nDisplay
The display will return to the original display if the satellite switches are not oper-
ated for an extended period.
Even if the display is in satellite switch mode, it will switch in the event of a warning
or when the radar cruise control (if equipped) is used. If this occurs, press any of the
satellite switches or “DISP” switch on the steering wheel to return the display to sat-
ellite switch mode.

4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
nAutomatic car washes
lFold the mirrors back before washing the vehicle.
lBrushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
nHigh pressure car washes
lDo not allow the nozzles of the car wash to come within close proximity of the
windows.
lBefore car wash, check that the fuel filler door on your vehicle is closed prop-
erly.
nAluminum 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.
nBumpers
Do not scrub with abrasive cleaners.
Perform the following to protect the vehicle and maintain it in prime condi-
tion.
lWorking from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
lWash the vehicle body using a sponge or soft cloth, such as a
chamois.
lFor hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
lWipe away any water.
lWax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.

Maintenance and care
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new tire pressure warning valve and transmitter ID codes must be regis-
tered in the tire pressure warning computer and tire pressure warning
system must be initialized. Have tire pressure warning valve and transmit-
ter ID codes registered by your Lexus dealer. (→P. 329)
Initializing the tire pressure warning system
nThe tire pressure warning system must be initialized in the following
circumstances:
lWhen rotating the tires on vehicles differing with front and rear tire
inflation pressures.
lWhen changing the tire inflation pressure by changing traveling
speed.
lWhen changing the tire size.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the pressure benchmark.

Maintenance and care
nWhen to replace your vehicle’s tires
Tires should be replaced if:
lYou have tire damage such as cuts, splits, cracks deep enough to expose the
fabric or bulges indicating internal damage
lA tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with your Lexus dealer.
nReplacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered,
the tire pressure warning system will not work properly. After driving for about 20
minutes, the tire pressure warning light comes on after blinking for 1 minute to indi-
cate a system malfunction.
nTire life
Any tire over 6 years old must be checked by a qualified technician even if they
have seldom or never been used or damage is not obvious.
nIf the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
nLow profile tires (models not equipped with 16-inch tires)
Generally, low profile tires will wear more rapidly and tire grip performance will be
reduced on snowy and/or icy roads when compared to standard tires. Be sure to
use snow tires or tire chains* on snowy and/or icy roads and drive carefully at a
speed appropriate for road and weather conditions.
*: Tire chains cannot be mounted on 18-inch tires.
nMaximum load of tire
Check that the maximum load of the replaced tire is greater than 1 /2 of the Gross
Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is
greater.
As for the maximum load of the tire, see the load limit at maximum cold tire inflation
pressure mentioned on the sidewall of the tire, and as for the Gross Axle Weight
Ratings (GAWR), see the Certification Label. (→P. 3 3 6 , 4 4 9 ) .

nTire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway driving
under dry conditions. Since summer tires do not have the same traction perfor-
mance as snow tires, summer tires are inadequate for driving on snow-covered
or icy roads. For driving on snow-covered roads or icy roads, the use of snow tires
is recommended. When installing snow tires, be sure to replace all four tires.
2 All season tires
All season tires are designed to provide better traction in snow and to be ade-
quate for driving in most winter conditions, as well as for use year round. All sea-
son tires, however, do not have adequate traction performance compared with
snow tires in heavy or loose snow. Also, all season tires fall short in acceleration
and handling performance compared with summer tires in highway driving.
3Snow tires
For driving on snow-covered roads or icy roads, we recommend using snow tires.
If you need snow tires, select tires of the same size, construction and load capac-
ity as the originally installed tires. Since your vehicle has radial tires as original
equipment, make sure your snow tires also have radial construction. Do not install
studded tires without first checking local regulations for possible restriction.
Snow tires should be installed on all wheels. (→P. 2 0 0 )
nInitializing the tire pressure warning system
Initialize the tires with the tire inflation pressure adjusted to the specified level.
nWhen the initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following cases,
the settings have not been recorded and the system will not operate properly. If
repeated attempts to record tire inflation pressure settings are unsuccessful, have
the vehicle inspected by your Lexus dealer.
lWhen operating the tire pressure warning reset switch, the tire pressure warn-
ing light does not flash 3 times and the setting message does not appear on the
multi-information display.
lAfter carrying out the initialization procedure, the tire pressure warning light
blinks for 1 minute then stays on after driving for about 20 minutes.

CAUTION
nTire pressure warning system operation
The tire pressure warning system may not provide warning immediately if a tire
bursts or if sudden air leakage occurs.
nWhen inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so may cause
damage to parts of the drive train, as well as dangerous handling characteristics,
which may lead to fatal or injury accidents.
lDo not mix tires of different makes, models, tread patterns or treadwear.
lDo not use tire sizes other than those recommended by Lexus.
lDo not mix radial, bias-belted, or bias-ply tires.
lDo not mix summer, all season and winter tires.
lDo not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
nWhen initializing the tire pressure warning system
Do not press the satellite switch without first adjusting the tire inflation pressure to
the specified level. Otherwise, the tire pressure warning light may not come on
even if the tire inflation pressure is low, or it may come on when the tire inflation
pressure is actually normal.
NOTICE
nRepairing or replacing tires, wheels and tire pressure warning valves and trans-
mitters
When removing or fitting the wheels, tires or the tire pressure warning valve and
transmitter, contact your Lexus dealer as the tire pressure warning valve and trans-
mitter may be damaged if not handled correctly.
nTo avoid damaging the tire pressure warning valves and transmitters
Do not use liquid sealants on flat tires.
