ELECTRONIC THROTTLECONTROL SYSTEM
The electronic throttle control system always maintains
appropriate engine output in relation to the accelerator
opening in all driving conditions.
SV31019
1Power position 2Normal position
3Snow position
The electronic throttle control system has 3 modes:
Normal, Power and Snow modes.
Normal mode: For ordinary driving, Lexus recommends that
you use the normal mode to improve fuel economy.
Power mode: For more powerful acceleration and sporty
driving. In the power mode, the ºECT 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 normal
mode.
To return to the normal mode, push the ºPWRº switch again.
Snow mode: Decreases the engine output to minimize rear
wheel spinning on snowcovered or slippery roads.
When you push ºSNOWº switch, the snow mode is turned on
and the ºSNOWº light in the instrument cluster comes on.
To return to the normal mode, push the ºSNOWº switch again.
The ºSNOWº indicator light will go off.
When you turn the ignition switch off in the snow mode, the
mode automatically changes to the normal mode.

CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired speed over 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 great
speed change will occur so it is better to drive without the cruise
control.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the selector switch.
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 on the system
SV31029
To operate the cruise control, push the main switch. 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 main switch is also
automatically turned off. To use the cruise control again, push
the main switch again to turn it on.
CAUTION
To avoid accidental cruise control engagement, keep
the main switch off when not using the cruise control.

4Resetting 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
ºMº 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.
5 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.

TRACTION CONTROL SYSTEM
The traction control system automatically help control the
spinning of the rear wheels which may occur when
accelerating on slippery road surfaces, thus assisting
driver control the driving power of the rear wheels. When
you turn the ignition switch on, the traction control
system always turns on automatically, and the slip
indicator light w ill come on. The indicator lights will go off
after a few seconds.
SV31011
1Slip indicator light
2ºSNOWº indicator light
Leave the system on during ordinary driving so that it can
operate when needed. When traction control is applied,
the slip indicator light blinks. If your vehicle still skids
even though traction control is applied, more powerful
traction control is applied and the ºSNOWº indicator light
comes on. If the light flashes, this indicates a malfunction in the traction
control system. Contact your Lexus dealer as soon as
possible to service the vehicle.
SV31033
You 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 of your vehicle, caused by operation of the brakes.
This indicates the system is functioning properly.
Page 197 of 307
STARTING AND DRIVING
184When getting the vehicle out of mud or new snow, etc. the
traction control system will help operate to prevent the wheels
from spinning.
CAUTION
Under certain slippery road conditions, full traction of
the vehicle and power to the 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 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.
BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic
system with two separate sub±systems. If either sub±system
should fail, the other will still work. However, the pedal will be
harder to press, and your stopping distance will be longer.
Also, the brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a single brake
system. Have your brakes fixed immediately.
Brake booster
The brake booster uses engine vacuum to power±assist the
brakes. If the engine should quit while you are driving, you can
bring the vehicle to a stop with normal pedal pressure. There
is enough reserved vacuum for one or two stops but no more!
CAUTION
Do not pump the brake pedal if the engine stalls.
Each push on the pedal uses up your reserved
vacuum.
Even if the power assist is completely lost, the brakes
will still work. But you will have to push the pedal
hard, much harder than normal. And your braking
distance will be longer.

Driving on rough, gravel or snow±covered roads.
Driving with tire chains installed.
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 anti±lock brake system detects vehicle
speeds using the speed sensors 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.ºABSº warning light

The light comes on when the ignition key is turned to the ºONº
position. If the anti±lock brake system works properly, the light
turns off after a few seconds. Thereafter, if the system
malfunctions, the light comes on again.

STARTING AND DRIVING
187
When the ºABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system and/or the
traction control system do/does not operate, but the brake
system still operates conventionally.
When the ºABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system and/or the
traction
control system do/does not operate so that the wheels
could lock up during a sudden braking or braking on slippery
road surfaces.
If either of the following conditions occurs, this indicates
a malfunction somewhere in the parts monitored by the
warning light system. Contact your Lexus dealer as soon
as possible to service the vehicle.
The light does not come on when the ignition key is turned
to the ºONº position, or remains on.
The light comes on while you are driving.
A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If the ºABSº warning light remains on together with the
brake system warning light, immediately stop your
vehicle at a safe place and contact your Lexus dealer.
In this case, not only the anti±lock brake system will fail
but also the vehicle will become extremely unstable
during braking.
Drum±in±disc type parking brake system
Your vehicle has a drum±in±disc type parking brake system.
This type of brake system needs bedding±down of the brake
shoes periodically or whenever the parking brake shoes
and/or drums are replaced.
Have your Lexus dealer perform the bedding±down.

DRIVING TIPS
193
TIPS FOR DRIVING IN VARIOUSCONDITIONS
Always slow down in gusty crosswinds. This will allow you
much better control.
Drive slowly onto curbs and, if possible, at a right angle.
Avoid driving onto high, sharp±edged objects and other
road hazards. Failure to do so can lead to severe tire
damage resulting in tire bursts.
When parking on a hill, turn the front wheels until they touch
the curb so that the vehicle will not roll. Apply the parking
brake, and place the transmission in ºPº. If necessary, block
the wheels.
Washing your vehicle or driving through deep water may get
the brakes wet. To see whether they are wet, check that
there is no traffic near you and then press the pedal lightly.
If you do not feel a normal braking force, the brakes are
probably wet. To dry them, drive the vehicle cautiously while
lightly pressing the brake pedal with the parking brake
applied. If they still do not work safely, pull to the side of the
road and call a Lexus dealer for assistance.
CAUTION
Before driving off, make sure the parking brake is
fully released and that the parking brake reminder
light is off.
Do not leave your vehicle unattended while the
engine is running.
Do not rest your foot on the brake pedal while driving.
It can cause dangerous overheating, needless wear,
and poor fuel economy.
To drive down a long or steep hill, reduce your speed
and downshift. Remember, if you ride the brakes
excessively, they may overheat and not work
properly. See page 175.
Be careful when accelerating, upshifting,
downshifting or braking on a slippery surface. The
abrupt change in engine speed, such as sudden
acceleration or engine braking, could cause the
vehicle to spin or skid.
Do not drive in excess of the speed limit. Even if the
legal speed limit permits it, do not drive over 140 km/h
(85 mph) unless your vehicle has high±speed
capability tires. Driving over 140 km/h (85 mph) may
result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine
whether the tires on your vehicle are high±speed
capability tires or not before driving at such speeds.
Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a longer
stopping distance, and it may pull to one side when
the brakes are applied. Also, the parking brake will
not hold the vehicle securely.

DRIVING TIPS
197
Avoid unnecessary stopping and braking. Maintain a
steady pace. Try to time the traf fic signals so you only need
to stop as little as possible or take advantage of through
streets to avoid traffic lights. Keep a proper distance from
other vehicles to avoid sudden braking. This will also
reduce wear on your brakes.
Avoid heavy traffic or traffic jams whenever possible.
Do not rest your foot on the brake pedal. This causes
premature wear, overheating and poor fuel economy.
Maintain a moderate speed on highways. The faster you
drive, the greater the fuel consumption. By reducing your
speed, you will cut down on fuel consumption.
Keep the front wheels in proper alignment. Avoid hitting
the curb and slow down on rough roads. Improper
alignment not only causes faster tire wear but also puts an
extra load on the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free from mud, etc.
This not only lessens weight but also helps prevent
corrosion.
Keep your vehicle tuned±up and in top shape. A dirty air
cleaner, improper valve clearance, dirty plugs, dirty oil and
grease, brakes not adjusted, etc. all lower engine
performance and contribute to poor fuel economy. For
longer life of all parts and lower operating costs, keep all
maintenance work on schedule, and if you often drive under
severe conditions, see that your vehicle receives more
frequent maintenance (For scheduled maintenance
information, please refer to the ºOwner's Manual
Supplement / Maintenance Scheduleº.)
CAUTION
Never turn off the engine to coast down hills. Your
power steering and brake booster will not function
without the engine running. Also, the emission control
system operates properly only when the engine is
running.

IN CASE OF AN EMERGENCY
200
IF YOUR ENGINE STALLS WHILEDRIVING
If your engine stalls while driving . . . .
1. Reduce your speed gradually, keeping a straight line. Move
cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see ºIf your vehicle will not startº\
.
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work, so steering and
braking will be much harder than usual.
IF YOUR VEHICLE WILL NOT START
(a) Simple checks
Before making these checks, make sure you have followed the
correct starting procedure instructions in ºHow to start the
engineº on page 168 and that you have sufficient fuel. Since
your vehicle is equipped with the engine immobiliser system,
also check whether the other keys will start the engine. If they
work, your key may be broken. Have the key checked at your
Lexus dealer. If none of your keys work, the system is possibly
broken. Call your Lexus dealer. See ºKeysº on page 8.
If the engine is not turning over or is turning over too
slowly ±
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked,
the battery is discharged. You may try jump starting. See º(c)
Jump startingº for further instruction.
If the light is O.K., but the engine still will not start, it needs
adjustment or repair. Call a Lexus dealer, Roadside
Assistance or Customer Service Assistance. (See
ºForewordº.)
