gauge to see that you have sufficient fuel.
IGNITION SWITCH
31X002a
“START” Starter motor on. The key will return to the
“ON” position when released.
For starting tips, see page 258.
“ON” Engine on and all accessories on.
This is the normal driving position.
NOTICE
Do not leave the key in the “ON” position if the engine
is not running. The battery will discharge and the
electronic ignition system could be damaged.
“ACC” Accessories such as the radio operate, but the
engine is off.

STARTING AND DRIVING
257
If you leave the key in the “ACC” or “LOCK” position and open
the driver’s door, a buzzer will remind you to remove the key.
31X003a
“LOCK” Engine is off and the steering wheel is locked.
The ignition key can be removed only at this position.
To turn the key from “ACC” to the “LOCK” position, you must
put the transmission selector lever in the “P” position.
Once you remove the key, the engine immobilizer system is
automatically set. See “Engine immobilizer system” on page
11 .
When starting the engine, the key may seem stuck at the
“LOCK” position. To free it, first be sure the key is pushed all
the way in, and then rock the steering wheel slightly while
turning the key gently.
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to “ACC”.
It is not a malfunction if the needles on all meters and gauges
move slightly when the key is turned to the “ACC”, “ON” or
“START” position.
Several hours after the engine is turned off, you may hear a
sound coming from underneath the luggage compartment for
several minutes. This is normal operation and does not
indicate a malfunction. (See page vii.)

HOW TO START THE ENGINE
Cranking hold function
Once you turn the ignition key to “START” position and release
it, the cranking hold function continues to crank the engine in
“ON” position until it starts.
The function stops cranking the engine after about 25 seconds
maximum if the engine has not started yet. When you crank
the engine again, wait a few seconds and restart it.
If you hold the key in “START” position, the function will keep
cranking for about 30 seconds maximum.
Before cranking
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and accessories.
3. Put the selector lever in “P”. If you need to restart the engine
while the vehicle is moving, put the selector lever in “N”. A
starter safety device will prevent the starter from operating if
the selector lever is in any drive position.
4. Depress the brake pedal and hold it to the floor until driving
off.

Starting the engine
Before starting the engine, be sure to follow the instructions in
“Before cranking”.
Normal starting procedure
The multiport fuel injection system/sequential multiport fuel
injection system in your engine automatically controls the
proper air−fuel mixture for starting. You can start a cold or hot
engine as follows:
With your foot off the accelerator pedal, turn the ignition key to
“START” position, then release it.
Engine should be warmed up by driving, not in idle. For
warming up drive with smoothly turning engine until engine
coolant temperature is within normal range.
If the engine stalls ...
Simply restart it , using the correct procedure given in normal
starting.
If the engine will not start
See “If your vehicle will not start” on page 334.
NOTICE
 Do not race a cold engine.
 If the engine becomes difficult to start or stalls
frequently, have the engine checked immediately.
AUTOMATIC TRANSMISSION
Your automatic transmission has a shift lock system to
minimize the possibility of incorrect operation. This
means you can only shift out of “P” position when the
brake pedal is depressed with the ignition switch in “ON”
position ( )
31x542

STARTING AND DRIVING

The shift position is displayed on the instrument
cluster.
P: Parking, engine starting and key removal position
R: Reverse position
N: Neutral position
D: Normal driving position (Shifting into overdrive
possible)
4: Position for engine braking (Shifting into overdrive not
possible)
When the cruise control is being used, even if you
downshift from “D” to “4”, engine braking will not be
enabled because the cruise control is not cancelled. For
the operation to decrease the vehicle speed, see page
278.

2. Set the driving pattern selector switch to the “Normal”
position.
Your transmission has a driving pattern selector switch which
allows you to select either “Normal” or “Power” to suit your\
driving condition. For ordinary driving, Lexus recommends
that you use the “Normal” position to improve fuel economy.
3. For more powerful acceleration and sporty driving, use
the “Power” position.
In the “Power” position, the “ECT PWR” 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” position.

Turning the system on and off
31X604
To turn the cruise control on, press the “ON–OFF” button. The
“CRUISE” indicator light in the instrument cluster will come on
to indicate that the cruise control is operational. Pressing the
“ON–OFF” button again turns the system off.
When the system is turned off, cruising speed must be reset
when the cruise control is turned on again.
When the ignition key is turned off, the “ON–OFF” switch is
also automatically turned off. To use the cruise control again,
push the “ON–OFF” switch again to turn it on.
CAUTION
To avoid accidentally engaging the cruise control, turn
the system off when it is not in use. Make sure the
“CRUISE” indicator light is off.
Setting operation
31X605
 Each function is described below.
1
Setting the cruise speed.
The transmission must be in “D” or “4” before you set the
cruising speed.
Bring the vehicle to the desired speed, press the control lever
downward in the “– SET” 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 pe dal, the vehicle will return to the speed set prior
to the acceleration.

STARTING AND DRIVING
289
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 active traction control
system is in the self
−check mode, and does not indicate
malfunction. When the active traction control system is
operating, you may feel vibration or hear 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 newly fallen snow, etc.,
the active traction control system will help operate to prevent
the wheels from spinning.
31X503
 Active traction control system failure warning
This light warns when there is a problem somewhere in the
active traction control system or vehicle stability control
system.
If the “VSC/TRAC” warning light comes on, have your vehicle
checked by your Lexus dealer as soon as possible. The brake actuator temperature increases during the active
traction control system or vehicle stability control system
operating. If the brake actuator temperature becomes too high
while the active traction cont
rol system or vehicle stability
control system is operating, a buzzer will start to sound
intermittently to indicate that the active traction control system
can no longer operate. In this case, immediately stop your
vehicle at a safe place. If the system continues to operate, the
buzzer sound changes from intermittent to continuous. (The
continuous buzzer sound will stop after about 3 seconds.) At
the time the “VSC/TRAC” warning light will come on and the
active traction control system temporarily stops operating in
order to protect the brake actuator. (Although the active
traction control system does not operate, there is no problem
to continue your driving.) The system will be automatically
restored after a short time and “VSC/TRAC” warning light goes
off if the accelerator pedal is released.
When the “ABS” warning light comes on, the active traction
control system is not operating.
The “VSC/TRAC” warning light will come on when the ignition
key is turned to “ON”, and will go off after a few seconds.
The “VSC/TRAC” warning light may stay on for 60 seconds
after the ignition key is turned to the “ON” position. It is normal
if it goes off after a few seconds.
Depressing the brake pedal repeatedly may turn on the
“VSC/TRAC” warning light. It is normal if it goes off after a few
seconds.
When the “VSC/TRAC” warning light comes on, the active
traction control system is not operating, but there is no problem
if you continue to drive.

STARTING AND DRIVING
291
The vehicle stability control system is activated 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
begins to move. This means that the vehicle stability control
is in the self−
check mode and does not indicate a malfunction.
31X529
Pushing the center differential lock button automatically turns
the vehicle stability control system off. At this time, the “VSC
OFF” indicator comes on with the center differential lock
indicator light. (For details, see “Four −wheel drive system” on
page 266.)
31x505
 Vehicle stability control system failure warning
These lights warn when there is a problem somewhere in the
vehicle stability control system or active traction control
system.
If the “VSC/TRAC” warning light and “VSC OFF” indicator light
come on, have your vehicle checked by your Lexus dealer as
soon as possible. However, there is no problem even if the
“VSC/TRAC” warning light comes on when the brake actuator
temperature becomes high. (For details, see “Active traction
control system” on page 288.)
When the “ABS” warning light comes on, the vehicle stability
control system is not operating.
The lights will come on when the ignition key is turned to “ON”,
and will go off after a few seconds.
The lights may stay on for 60 seconds after the ignition key is
turned to the “ON” position. It is normal if they go off after a few
seconds.

STARTING AND DRIVING

Variable gear ratio steering system failure
warning
31x500b
This light warns that there is a problem somewhere in the
variable gear ratio steering 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 is not working.
Although conventional steering operates when maneuvered,
a larger degree of wheel maneuvering (than at the time when
the system is functioning properly) is needed when driving at
low speed. At this time, the center position of the steering
wheel could be changed. Although it is no problem to continue
driving, have your vehicle repaired at your Lexus dealer. 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.
