Resetting to a faster speed
Press the control lever upward in the ºRES/ACCº
direction and hold it. Release the lever when the desired
speed is attained. While the lever is held upward, the
vehicle will gradually gain speed.
When the difference between the actual vehicle speed
and the set speed is less than 5 km/h (3 mph), the set
speed can be increased 1.6 km/h (1 mph) each time by
pressing the control lever upward in the ºRES/ACCº
direction quickly.
However, a quicker way to reset is to accelerate the
vehicle and then press the control lever downward in the
ºSET/COASTº direction.
Resetting to a slower speed
Press the control lever downward in the ºSET/COASTº
direction and hold it. Release the lever when the desired
speed is attained. While the lever is held downward, the
vehicle speed will gradually decrease.
When the difference between the actual vehicle speed
and the set speed is less than 5 km/h (3 mph), the set
speed can be lowered 1.6 km/h (1 mph) each time by
pressing the control lever downward in the
ºSET/COASTº direction quickly.
However, a quicker way to reset is to depress the brake
pedal and then press the control lever downward in the
ºSET/COASTº direction.
Even if you turn off the overdrive switch with the cruise
control on, engine braking will not be applied because
the cruise control is not cancelled. To decrease the
vehicle speed, reset to a slower speed with the cruise
control lever or depress the brake pedal. If you use the
brake pedal, cruise control is cancelled.
Resuming the preset speed
If the preset speed is cancelled by pulling the control
lever or by depressing the brake pedal, pushing the lever
up in the ºRES/ACCº direction will restore the speed set
prior to cancellation. However, once the vehicle speed
falls below about 40 km/h (25 mph), the preset speed will
not be resumed.

Cruise control failure warning
If the ºCRUISEº indicator light in the instrument cluster
flashes five times and then goes out when using the
cruise control, it means that there is trouble in the cruise
control system. Contact your Lexus dealer.
ELECTRONIC MODULATED SUSPENSION
This electronic modulated suspension adjusts the
damping effect on the shock absorbers with the
control switch. Select one of the 4 modes which is
suited to the driving conditions with the control
switch to provide good riding comfort and stability.

TRACTION CONTROL SYSTEM
The traction control system automatically helps
control the spinning of the front wheels which may
occur when accelerating on slippery road surfaces,
thus assisting driver to control the driving power of
the front wheels.

STARTING AND DRIVING
280You can turn off the traction control system by
pushing the ºTRAC OFFº switch. The ºTRAC OFFº
indicator/warning light will then come on. Pushing
the ºTRAC OFFº switch a second time turns the
system back on and extinguishes the ºTRAC OFFº
indicator/warning light.
You may hear a sound in the engine compartment for a
few seconds when the engine is started or just after the
vehicle is started. This means that the traction control
system is in the self
±check mode, and does not indicate
malfunction.
When the traction control system is operating, you may
feel vibration or noise of your vehicle, caused by
operation of the brakes. This indicates the system is
functioning properly.
When getting the vehicle out of mud or new snow, etc.
the traction control system will help operate to prevent
the wheels from spinning.

Traction control failure warning
If the ºTRAC OFFº indicator/warning light flashes,
contact your Lexus dealer as soon as possible. There
may be trouble in the traction control system.
CAUTION
Under certain slippery road conditions, full traction of
the vehicle and power to the front 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 will cause the vehicle
to lose traction. 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 pace.

VEHICLE SKID CONTROLSYSTEM
The vehicle skid control system helps provide
comprehensive control of the systems such as an
anti±lock brake system, traction control, engine
control, etc. This system automatically controls the
output of the brakes or engine to help prevent the
vehicle from skidding when cornering on a slippery
road surface or abrupt steering wheel operation
occurs.
31E013±1

Slip indicator light
If the vehicle is going to skid during driving, the slip
indicator light flashes and an alarm sounds
intermittently.
The vehicle skid control activates when the vehicle
speed is about more than 15 km/h (9 mph). You may hear a sound in the engine compartment for a
few seconds when the engine is started or just after the
vehicle is started. This means that the vehicle skid
control is in the self±check mode and does not indicate
a malfunction.

These lights warn that when there is a problem
somewhere in the vehicle skid control system or traction
control system.
If the ºVSCº warning light and ºVSC OFFº indicator light
come on, have your vehicle checked by Lexus dealer as
soon as possible.
The lights will come on when the ignition key is turned to
ªONº, and will go off after about a few seconds.

control system do not work. However, as conventional
braking operates when applied, there is no problem to
continue your driving.
