1Power position 2Normal position
3Snow position
2. Set the driving pattern selector switch to the ªNormalº
position.
Your transmission has a driving pattern selector switch which
allows you to select ªPowerº, ªNormalº or ªSnowº mode \
to suit
your driving condition. For ordinary driving, Lexus
recommends that you use the ªNormalº position to improve fuel
economy.
3. For more powerful acceleration and sporty driving, use
the ªPowerº position.
In the ªPowerº position, the ªECT PWRº light in the instrument\
cluster is on and the transmission is shifted up at higher vehicle
speeds and shifted down more responsively than in the
ªNormalº position.
For ªSnowº mode, see ªElectronic Throttle Control
Systemº on page 260.

1Brake pedal 2ªDº (Drive) position
4. With your foot holding down the brake pedal, shift the
selector lever to ªDº.
Always use the ªDº position to improve fuel economy and quiet
driving. In this position, shifting into the overdrive gear is
possible. However, while the engine coolant temperature is
low, the transmission will not shift into the overdrive gear even
in the ªDº position. (See ª(c) Using engine brakingº and \
ª(g)
Good driving practiceº for exceptions.)
CAUTION
Never put your foot on the accelerator pedal while
shifting.

5. Release
the parking brake and brake pedal. Depress the
accelerator pedal slowly for smooth starting.
In normal cruising, the vehicle will start in the first gear and
automatically shift up to the most suitable gear. On inclines,
declines or winding roads, etc., the vehicle shifts up and down
automatically according to the running conditions to obtain the
suitable driving power and engine braking.
When the lever is in ª3º position, the automatic transmission
system will select the most suitable gear for the running
conditions such as hill climbing, hard towing, etc.
If you need to accelerate rapidly while driving, depress the
accelerator pedal to the full throttle position. This provides
more acceleration by automatically downshifting the
transmission to the next lower gear or beyond, depending on
the vehicle speed.
If engine braking is needed, such as in descending a long hill,
see ª(c) Using engine brakingº.
(b) Driving in M mode
If the change lever is shifted to M position, the shift range
position can be switched over between 5 and 2 using the
shift switch on the steering wheel instead of operating the
change lever. The first shift range position is on 5 when
the change lever is shifted to M position.

(g) Good driving practice
If the transmission repeatedly shifts up and down between the
fourth and overdrive gears when climbing a gentle slope, shift
the selector lever to the ªMº position and select the fourth gear
by pushing the transmission switch. Be sure to shift the
selector lever to the ªDº position after climbing the slope.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Always use the brake pedal or the parking brake to hold
the vehicle on an upgrade. Do not attempt to hold the vehicle using the accelerator pedal, as this can causethe transmission to overheat.
(h) If you cannot shift the selector
If you cannot shift the selector lever even though the brake
pedal is depressed, use the shift lock override button. For
instructions, see ªIf you cannot shift automatic transmission
selector leverº on page 304.
(i) If the ªECT PWRº indicator light flashes
If the ªECT PWRº indicator light flashes, contact your Lexus
dealer as soon as possible. There may be trouble in the
transmission system.

MANUAL TRANSMISSION
SV31034
The shift pattern is the conventional pattern shown above.
CAUTION
The shift lever knob can become extremely hot after
parking under the sun.
Press the clutch pedal down fully while shifting, and then
release it slowly. Do not rest your foot on the pedal while
driving, because it will cause clutch trouble. Do not use the
clutch to hold the vehicle when stopped on an uphill grade ±
use the parking brake.
Upshifting too soon or downshifting too late will cause lugging,
and possibly pinging. Regularly revving the engine to
maximum speed in each gear will cause excessive engine
wear and high fuel consumption.Recommended shifting speeds
The transmission is fully synchronized and upshifting or
downshifting is easy.
For the best compromise between fuel economy and vehicle
performance, you should upshift or downshift at the following
speeds:
gear km/h (mph)
1 to 2 or 2 to 1 24 (15)
2 to 3 or 3 to 2 40 (25)
3 to 4 or 4 to 3 64 (40)
4 to 5 or 5 to 4 72 (45)
Downshift to the appropriate gear if acceleration is needed
when you are cruising below the above downshifting speeds.
Upshifting too soon or downshifting too late will cause lugging,
and possibly pinging. Regularly revving the engine to
maximum speed in each gear will cause excessive engine
wear and high fuel consumption.
Maximum allowable speeds
To get on a highway or to pass slower traffic, maximum
acceleration may be necessary. Make sure you observe the
following maximum allowable speeds in each gear: gear km/h (mph)1 56 (35)
2 98 (61)
3 145 (91)

Setting operation
SV31030

Each function is described below.
1Setting at a desired speed.
Automatic transmission: The transmission must be in the
ªDº position or the gear position must be ª4º or ª5º in M mode
before you set the cruise control speed.
Bring the vehicle to the desired speed, press the control lever
downward in the ªSET/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.
2Cancelling the preset speed
You can cancel the preset speed by either of the following:
a. Pulling the control lever in the ªCANCELº direction.
b. Depressing the brake pedal.
c. Depressing the clutch pedal (manual transmission)
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.
3Resetting to a faster speed
Press the control lever upward in the ªRES/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 ªRES/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
ªSET/COASTº direction.

4Resetting to a slower speed
Press the control lever downward in the ªSET/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 ªSET/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
ªSET/COASTº direction.
Automatic transmission: Even if you downshift the
transmission from the ªDº position to ªMº 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.
5Resuming 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
ªRES/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 ªCRUISEº 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.

TRACTION CONTROL SYSTEM
(With vehicle stability control system)
The traction control system automatically helps prevent
the spinning of rear 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 against rear 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.
Normal driving mode
SV31037

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 just after the vehicle begins to move. This means that
the traction control system is in the self±check mode, but does
not indicate a malfunction.
When the traction control system is operating, the following
conditions occur:
 The system controls the spinning of the rear 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.
