STEERING WHEEL AND MIRRORS
193
Automatic tiltaway*
16X100f
When the ignition key is removed, the steering column
moves forward away from the driver and also tilts up for
easy exit and entry.
When the key is inserted in the ignition switch, the steering
column returns to the previously set position.NOTE: *This feature can be deactivated. Ask your Lexus
dealer for details.
OUTSIDE REAR VIEW MIRRORS
16X013a
Adjust the mirror so that you can just see the side of your
vehicle in the mirror.
Be careful when judging the size or distance of any object seen
in the outside rear view mirror on the passenger’s side
because it is a convex mirror. Any object seen in a convex
mirror will look smaller and farther away than if seen in a normal
flat mirror.
When the inside rear view mirror darkens in “AUTO” mode, the
outside rear view mirrors also darken to reduce the reflection
of the headlights of the following vehicle. For details, see
“Inside rear view mirror” on page 196.
When you push the outside rear view mirror defogger switch,
the heater panels in the outside rear view mirrors will quickly
clear the mirror surface. (See “Outside rear view mirror
defogger switch” on page 38.)

STARTING AND DRIVING
292Depressing
the brake pedal repeatedly may turn on the lights.
It is normal if they go off after a few seconds.
When the “VSC/TRAC” warning light and “VSC OFF” indicator
light come on, the vehicle stability control system is not
operating, but there is no problem if you continue to drive.
In the following cases, contact your Lexus dealer:
 The “VSC/TRAC” warning light, “VSC OFF” indicator light
and slip indicator light do not come on after the ignition is
turned to on.
 The “VSC/TRAC” warning light and “VSC OFF” indicator
light remain on after the ignition is turned to on.
 The “VSC OFF” indicator light comes on while driving
without pushing the center differential lock switch.
CAUTION
Active traction control system, vehicle stability
control system and antilock brake system are
electronic systems designed to help the driver
maintain control under adverse conditions. They are
not a substitute for safe driving practices. Factors
including speed, road conditions and driver steering
input can all affect whether active traction control
system, vehicle stability control system and
antilock brake system will be effective in preventing
a loss of control. Always keep safety driving in mind.
If the slip indicator light flashes, sounding an alarm,
special care should be taken while driving.
 Only use tires of specified size. The size,
manufacturer, brand and tread pattern for all 4 tires
should be the same. If you use the tires other than
specified, or different type or size, the vehicle
stability control system may not function correctly.
When replacing the tires or wheels, contact your
Lexus dealer. (See “Checking and replacing tires” on
page 438.)

STARTING AND DRIVING
297
Driving over the steps such as the joints on the road.
 Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure: The antilock brake system detects vehicle
speeds using the speed s ensors for respective wheels’
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.“ABS” warning light
31X506
The light comes on when the ignition key is turned to the “ON”
position. If the anti−lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti−lock brake system, the brake
assist system, the active traction control system and/or the
vehicle stability control system do/does not operate, but the
brake system still operates conventionally.
When the “ABS” warning light is on (and the brake system
warning light is off), the anti− lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces.

STARTING AND DRIVING
305
Replacing tires and wheels
When replacing the tires and wheels, be sure to install tire
pressure warning valves and transmitters. ID codes on the tire
pressure warning valves and transmitters are registered on the
tire pressure warning ECU. When replacing a tire pressure
warning valve and transmitter, it is necessar y to register the ID
code of tire pressure warning valve and transmitter. Have the
ID code registered by your Lexus dealer.
If the ID code is not registered, the system will not work
properly. After about 1 hour, the tire pressure warning light
blinks to indicate a system malfunction.
NOTICE
When the tires or tire pressure warning valves and
transmitters must be replaced, have them replaced by
your Lexus dealer. The tire pressure warning valves
and transmitters will be affected by the installation or
removal of tires.
Tire pressure warning reset switch
31x612
When initializing the system, the present tire inflation pressure
is stored as standard. The tire pressure warning system
determines decreased air pressure by comparing the present
and the standard tire inflation pressures. When you change
the set tire inflation pressure, it is necessary to initialize the tire
pressure warning system.
 When rotating the tires on vehicles differing with front and
rear tire inflation pressures.
 When changing the tire inflation pressure by changing
traveling speed or load weight, etc.
 When changing the tire size.

DRIVING TIPS
320
Hitches
If you wish to install a trailer hitch, you should consult with
your Lexus dealer.
 Use only a hitch recommended by the hitch manufacturer
and the one which conforms to the total trailer weight
requirement.
 The hitch must be bolted securely to the vehicle frame and
installed according to the hitch manufacturer’s instructions.
 The hitch ball and king pin should have a light coat of
grease.
 Lexus recommends removing the trailer hitch whenever
you are not towing a trailer to reduce the possibility of
additional damage caused by the hitch if your vehicle is
struck from behind. After removing the hitch, seal any
mounting holes in the vehicle body to prevent entry of
pollutants such as exhaust fumes, dirt, water, etc.
NOTICE
Do not use axlemounted hitches as they can cause
damage to the axle housing, wheel bearings, wheels or
tires. Also, never install a hitch which may interfere with
the normal function of an Energy Absorbing Bumper, if
so equipped.
Trailer ball
Follow these easy steps to properly determine the correct
trailer ball for your application:
1. Determine the correct trailer ball size for the trailer coupler.
Most couplers are stamped with the required trailer ball size.
The sizes you’ll most likely find stamped on the coupler are:
Trailer Class
Typical Trailer Ball Size
III 2 in.
II 2 in.
I 1 7/8 in.
2. Select the appropriate trailer ball to match or exceed the
gross trailer weight rating of the trailer. The trailer ball load
rating should be printed on the top of the ball.
