(f) Good driving practice
If the transmission repeatedly upshifts and
downshifts between the fourth and overdrive gears
when climbing a gentle slope, shift the selector lever
to the º4º position. Be sure to shift the selector lever
to the ºDº position after climbing the slope.
 When towing a trailer, in order to maintain efficient
engine braking and electrical charging performance,
do not use overdrive. The selector lever must be in
the º4º position.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Do not hold the vehicle on an upgrade with the accelerator pedal. This can cause thetransmission to overheat. Always use the brakepedal or parking brake.

CAUTION
If your vehicle becomes stuck in snow, mud, sand, etc.,
then you may attempt to rock the vehicle free by moving
it forward and backward. Do not attempt this procedure
if people or objects are anywhere near the vehicle.
During the rocking operation the vehicle may suddenly
move forward or back as it becomes un±stuck, causing
injury or damage to nearby people or objects.
NOTICE
If you rock your vehicle, observe the following
precautions to prevent damage to thetransmission and other parts.
Do not depress the accelerator pedal whileshifting the selector lever or before thetransmission is completely shifted to forwardor reverse gear.
Do not race the engine and avoid spinning thewheels.
If your vehicle remains stuck after rocking thevehicle several times, consider other wayssuch as towing.
(h) If you cannot shift the selector lever
If you cannot shift the selector lever even though the
brake pedal is depressed, use the shift lock override
button. For instructions, see ºIf you cannot shift
automatic transmission selector leverº on page 375.

Setting at a desired speed
31L068
The transmission must be in ºDº or º4º before you set the
cruise control speed.
Bring the vehicle to the desired speed, press the control
lever downward in the ºSET/COASTº direction and
release it. This sets the vehicle at that speed. Now you
may take your foot off the accelerator pedal. If you need
acceleration ± for example, when passing ± depress the
accelerator pedal enough for the vehicle to exceed the
set speed. When you release the accelerator pedal, the
vehicle will return to the speed set prior to the
acceleration.Cancelling the preset speed
You can cancel the preset speed by either of the
following:
a. Pulling the control lever in the ºCANCELº direction.
b. Depressing the brake pedal.
If the vehicle speed falls below about 40 km/h (25 mph),
the preset speed will be automatically cancelled.
If the vehicle speed drops 16 km/h (10 mph) below the
preset speed, the preset speed will also automatically be
cancelled.
If the preset speed automatically cancels out for other
than these reasons, have your vehicle checked by your
Lexus dealer at the earliest opportunity.

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 within 0.6 seconds.
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 within 0.6 seconds.
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 downshift the transmission from the ºDº
position to º4º 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.

301
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 when using the cruise control, push the main
switch to turn the system off and then push it again to
turn it on.
If any of the following conditions then occurs, there is
some trouble in the cruise control system.
 The indicator light does not come on.
 The indicator light flashes again.
 The indicator light goes out after it comes on.
If this is the case, contact your Lexus dealer and have
your Lexus inspected.
ELECTRONICALLY
MODULATED AIR SUSPENSION
(U.S.A. ONLY)
This electronically modulated air suspension
adjusts the damping effect on the shock absorbers
and the vehicle height. This adjustment is
automatically made in response to the driving
conditions to provide good riding comfort and
stability in all driving conditions.

When you turn the ignition switch on, this system
always turns on. Leave the system on during
ordinary driving so that it can operate when needed.
When traction control is applied, the slip indicator
light blinks.
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 vi bration 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.
To turn off the traction control system, see page 309.

VEHICLE SKID CONTROLSYSTEM
The vehicle skid control system helps to provide
comprehensive control of the systems such as an
anti±lock brake system, traction control, engine
control, electronically modulated air suspension,
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.
