the following parts.
(a) Normal driving
(b) Using engine braking
(c) Using the ª3º, ª2º and ªLº positions
(d) Backing up
(e) Parking
(f) Good driving practice

(a) Normal driving

1ªPº (Park) position2ªNº (Neutral) position
1. Start the engine as instructed in ªHow to start the
engineº on page 401.

art
in any drive position even if the ignition key is turned to
ªSTARTº.

STARTING AND DRIVING

CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired speed over about 40 km/h (25 mph) with your foot
off the accelerator pedal.
Your cruising speed can be maintained although a slight speed
change may occur when driving up or down a gradient, within
the limits of engine performance. On steeper hills, a greater
speed change will occur so it is better to drive without the cruise
control.
CAUTION
 To help maintain maximum control of your vehicle,
do not use the cruise control when driving in heavy
or varying traffic, or on slippery (rainy, icy or
snow±covered) or winding roads.
 Avoid vehicle speed increases when driving
downhill. If the vehicle speed is too fast in relation to
the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.
Turning the system on
To operate the cruise control, push the ªON±OFFº button. This
turns the system on. The indicator light in the instrument
cluster shows that you can now set your desired cruising
speed. Another push on the switch will turn the system
completely off.
When the ignition key is turned off, the ªON±OFFº button is also
automatically turned off. To use the cruise control again, push
the ªON±OFFº button again to turn it on.
CAUTION
To avoid accidental cruise control engagement, keep
the ªON±OFFº button off when not using the cruise
control.

STARTING AND DRIVING
430We recommend you to select the mode

2
for ordinary
driving. The damping effect will be changed automatically to
provide good riding comfort.
When your vehicle is loaded heavily or you are driving in an
unpaved road, the mode
3
or 4
will be recommended. To
provide good vehicle stability, the damping effect will be harder
than for ordinary driving mode.
With the four±wheel drive control lever at ªLº, the damping
effect suitable for off±road driving will be provided in any mode.
ACTIVE TRACTION CONTROL
SYSTEM
The active traction control system automatically helps
prevent the spinning of 4 wheels when the vehicle is
started or accelerated on slippery road surfaces.
When the ignition key is turned to ªONº, the system
automatically turns on.
CAUTION
Under certain slippery road conditions, full traction of
the vehicle and power to the 4 wheels cannot be
maintained, even though the traction control system is
in operation. Do not drive the vehicle under any speed
or maneuvering conditions which may cause the
vehicle to lose traction control. In situations where the
road surface is covered with ice or snow, your vehicle
should be fitted with snow tires or tire chains. Always
drive at an appropriate and cautious speed for the
present road conditions.

Slip indicator light
Leave the system on during the ordinary driving so that it
can operate when needed.
You may hear a sound in the engine compartment for a few
seconds when the engine is started or just after the vehicle
begins to move. This means that the active traction control
system is in the self±check mode, but does not indicate a
malfunction.
When the active traction control system is operating, the
following conditions occur:
 The system controls the spinning of the 4 wheels. At this
time, the slip indicator light blinks.
 You may feel vibration or noise in your vehicle, caused by
operation of the brakes. This indicates the system is
functioning properly. The slip indicator light comes on for a few seconds when the
ignition key is turned to ªONº. If the indicator light does not
come on when the ignition is turned on, contact your Lexus
dealer.
The brake actuator temperature increase during continuous
operation of the following systems.

Active traction control system
 Vehicle stability control system
 Downhill assist control system
 Hill±start assist control
If the brake actuator temperature becomes too high while any
of the systems is operating, a buzzer will start to sound
intermittently to indicate that the active traction control system
can no longer operate. In this case, immediately stop your
vehicle at a safe place.
If the system continues to operate, the buzzer sound changes
from intermittent to continuous. (The continuous buzzer
sounds for about 3 seconds.) At the time, the slip indicator light
will come on and the active traction control system temporarily
stops operating in order to protect the brake actuator.
(Although the active traction control system does not operate,
there is no problem to continue your driving.) The system will
be automatically restored after a short time and the slip
indicator light goes out.

ªVSC TRACº warning light
This light warns that there is a problem somewhere in the
following.
Active traction control system
 Vehicle stability control system
 Downhill assist control system
 Hill±start assist control
When the system is normal and the ignition key is turned to
ªONº, the warning light will come on and will go off after a few
seconds. It is not a malfunction that the warning light may stay
on for 60 seconds after the ignition key is turned to the ªONº
position. Depressing the brake pedal repeatedly may turn on the light.
It is normal if it goes out after a few seconds.
If the ªVSC TRACº warning light and slip indicator light comes
on while driving, the active traction control system does not
work. However, as normal braking operates when being
applied, there is no problem to continue your driving.
In the following cases, contact your Lexus dealer:

The warning light does not come on after the ignition key is
turned to ªONº.
 The warning light remains on after the ignition key is turned
to ªONº.
 The warning light comes on while driving.

STARTING AND DRIVING
434If the brake pedal is depressed while the vehicle stability
control system is active, the brake pedal will become hard at
an earlier position than usual. However, the brakes will
respond to the pedal force if depressed further.
The slip indicator light comes on for a few seconds when the
ignition key is turned to ªONº. If the indicator light does not
come on when the ignition is turned on, contact your Lexus
dealer.
Pushing the center differential lock switch automatically
turns
the vehicle stability control system off. At this time,
the ªVSC OFFº indicator comes on with the center
differential lock indicator light.
ªVSC OFFº indicator light comes on for a few seconds when
the ignition key is turned to ªONº. It will come on again when
you push the center differential lock switch to turn off the
system. In the following cases, contact your Lexus dealer:

Slip indicator light
With the vehicle traveling at a speed of 25 km/h (15 mph) or
less, release your foot from the accelerator or brake pedal to
activate the system. The vehicle will descend the hill at a low
speed. While the system is operating, the slip indicator light on
the instrument panel will flash and the stop lights and high
mounted stoplight will be lit.
If you push the ªDACº switch to turn the system off while it is
in operation, the system will stop operating gradually. The
downhill assist control system indicator light will flash to alert
the driver. To continue driving at a low speed, push the ªDACº
switch to turn the system on.
The slip indicator light and downhill assist control system
indicator l
ight come on for a few seconds when the ignition key
