(c) Using the “3”, “2” and “L” positions
The “3”, “2” and “L” positions are used for strong engine\
braking
as described previously.
With the selector lever in “3”, “2” or “L”, you can start the vehicle
in motion as with the lever in “D”.
With the selector lever in “3” or “2”, the vehicle will start in firs\
t
gear and automatically shift to second gear or third gear.
With the selector lever in “L”, the transmission is engaged in
first gear.
NOTICE
 Be careful not to overrev the engine. Watch the
tachometer to keep engine rpm from going into the
red zone. The approximate maximum allowable
speed for each position is given above for your
reference.
“3” 133 km/h (82 mph). . . . . . . .
“2” 85 km/h (53 mph) . . . . . . . . .
“L” 47 km/h (29 mph) . . . . . . . . .
 Do not continue hill climbing or hard towing for a long
time in the “3”, “2” or “L” position. This may cause
severe automatic transmission damage from
overheating. To prevent such damage, “4” position
should be used in hill climbing or hard towing.
(d) Backing up
1Brake pedal2“R” (Reverse) position
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the
selector lever to the “R” position.
NOTICE
Never shift into reverse while the vehicle is moving.
Vehicles with driving position memory system —
When the selector lever is shifted into the “R” position, the
outside rear view mirrors automatically down to help backing
up. For details, see page 172.

3“P” (Park) position
1. Bring the vehicle to a complete stop.
2. Depress the parking brake fully to securely apply the
parking brake.
3. With the brake pedal held down with your foot, shift the
selector lever to the “P” position.
CAUTION
Never attempt to move the selector lever into “P” under
any circumstances while the vehicle is moving. Serious
mechanical damage and loss of vehicle control may
result.
(f) Good driving practice
 If the transmission repeatedly shifts up and down between
fourth and overdrive gears when climbing a gentle slope,
shift the selector lever to the “4” position. Be sure to shift the
selector lever to the “D” position after climbing the slope.
 When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive.
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 cause
the transmission to overheat.
(g) 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 “If you cannot shift automatic transmission
selector lever” on page 322.

STARTING AND DRIVING

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.
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
snowcovered) 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 “ON− OFF” 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 button 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 “ON− OFF” button again to turn it on.
CAUTION
To avoid accidental cruise control engagement, keep
the “ONOFF” button off when not using the cruise
control.

4Resetting to a slower speed
Press the control lever downward in the “ − SET” 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 “ − SET” direction quickly.
However, a quicker way to reset is to depress the brake pedal
and then press the control lever downward in the “ − SET”
direction.
Even if you downshift the transmission from the “D” position to
“4” with the cruise control on, engine braking will not be
enabled 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
“+ RES” direction will restore the speed set prior to
cancellation.
Cruise control failure warning
If the “CRUISE” indicator light in the instrument cluster flashes
when using the cruise control, push the ”ON −OFF” button 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. Contact your Lexus dealer
and have your Lexus inspected.
 The indicator light does not come on.
 The indicator light flashes again.
 The indicator light goes out after it comes on.

STARTING AND DRIVING
270
Normal driving mode
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 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 front 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 “ON”. If the indicator light does not
come on when the ignition is turned on, contact your Lexus
dealer.
Traction control off mode
If your wheels get stuck in a ditch when you are driving on
a severe off road and sand, turn off the traction control
system. This system that controls engine performance
interferes with the process of freeing your wheels.
To turn off: Push “TRAC OFF” switch.
The “TRAC OFF” indicator light will come on.
The vehicle stability control system is always activated, even
if the traction control system is turned off.

STARTING AND DRIVING
272This light warns that there is a problem somewhere in the
traction control system or the vehicle stability control system.
The light will come on when the ignition key is turned to “ON”
and will go off after a few seconds.
If the light comes on while driving, the system does not work.
However, as conventional braking operates when 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 “ON”.
 The warning light remains on after the ignition key is turned
to “ON”.
 The warning light comes on while driving.
The “TRAC OFF” indicator light will come on when the “VSC”
warning light comes on even if the “TRAC OFF” switch is not
pushed.
VEHICLE STABILITY CONTROL SYSTEM
The vehicle stability control system helps provide
integrated control of the systems such as antilock brake
system, traction control, engine control, etc. This system
automatically controls the brakes and engine to help
prevent the vehicle from skidding when cornering on a
slippery road surface or operating steering wheel
abruptly.
This system will activate when your vehicle speed reaches or
exceeds 15 km/h (9 mph), and will deactivate when the vehicle
speed reduces to below 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
begins to move. This means that the system is in the
self−check mode but does not indicate a malfunction.
CAUTION
 Do not rely excessively on the vehicle stability
control system. Even if the vehicle skid control
system is operating, you must always drive carefully
and attentively to avoid serious injury. Reckless
driving will result in an unexpected accident. If the
slip indicator light blinks, sounding an alarm, special
care should be taken while driving.

STARTING AND DRIVING
274This light warns that there is a problem somewhere in the
vehicle stability control system or the traction control system.
The light will come on when the ignition key is turned to “ON”
and will go off after a few seconds.
If the light comes on while driving, the system does not work.
However, as conventional braking operates when 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 “ON”.
 The warning light remains on after the ignition key is turned
to “ON”.
 The warning light comes on while driving.
The “TRAC OFF” indicator light will come on when the “VSC”
warning light comes on even if the “TRAC OFF” switch is not
pushed.
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 increase. 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 increase.

STARTING AND DRIVING
275
Antilock brake system
The antilock brake system is designed to help prevent
lockup of the wheels during a sudden braking or braking
on slippery road surfaces. This assists in providing
directional stability and steering performance of the
vehicle under these circumstances.
Effective way to press the ABS brake pedal: When the
anti−lock brake system function is in action, you may feel the
brake pedal pulsating and hear a noise. In this situation, to
let the anti−lock brake system work for you, just hold the
brake pedal down more firmly. Do not pump the brake in a
panic stop. This will result in reduced braking performance.
The anti−lock brake system becomes operative after the
vehicle has accelerated to a speed in excess of approximately
10 km/h (6 mph). It stops operating when the vehicle
decelerates to a speed below approximately 5 km/h (3 mph).
Depressing the brake pedal on slippery road surfaces such as
on a manhole cover, a steel plate at a construction site, joints
in a bridge, etc. on a rainy day tends to activate the anti− lock
brake system. You may hear a click or motor 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
anti−lock brake system is in the self −check mode, and does not
indicate a malfunction.
When the antilock brake system is activated, the
following conditions may occur. They do not indicate a
malfunction of the system:
 You may hear the anti −lock brake system operating and feel
the brake pedal pulsating and the vibrations of the vehicle
body and steering wheel. You may also hear the motor
sound in the engine compartment even after the vehicle is
stopped.
 At the end of the anti−lock brake system activation, the
brake pedal may move a little forward.
CAUTION
Do not overestimate the antilock brake system:
Although the antilock brake system assists in
providing vehicle control, it is still important to drive
with all due care and maintain a moderate speed and
safe distance from the vehicle in front of you, because
there are limits to the vehicle stability and effectiveness
of steering wheel operation even with the antilock
brake system on.

STARTING AND DRIVING
278
Drumindisc 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.
Brake assist system (vehicles with vehicle
stability control system)
When you slam the brakes on, the brake assist system
judges as an emergency stop and provides more powerful
braking for a driver who cannot hold down the brake pedal
firmly.
When you slam the brakes on, more powerful braking will be
applied. At this time, you may hear a sound in the engine
compartment and feel the vibrations of the brake pedal. This
does not indicate a malfunction.
The brake assist system becomes operative after the vehicle
has accelerated to a speed in excess of approximately 10 km/h
(6 mph). It stops operating when the vehicle decelerates to a
speed below approximately 5 km/h (3 mph).
For an explanation of this system’s warning light, see “ABS
warning light” on page 64.
BRAKE PAD WEAR LIMIT INDICATORS
The brake pad wear limit indicators on your disc brakes
give a warning noise when the brake pads are worn to the
extent that replacement is required.
If you hear a squealing or scraping noise while driving, have the
brake pads checked and replaced by your Lexus dealer as
soon as possible. Expensive rotor damage can result if the
pads are not replaced when needed.

DRIVING TIPS
280
BREAKIN PERIOD
