At this time, vibration may occur. However, if you depress the
accelerator pedal more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle checked by your
Lexus dealer as soon as possible.
Even if the abnormality of the electronic throttle control system
is corrected during low speed driving, the system may not be
recovered until the engine is stopped and the ignition key is
turned to ACCº or LOCKº position.
CAUTION
Be especially careful to prevent erroneous pedal
operation.
Emissions inspection and maintenance (I/M) programs
Your vehicle may not pass a state emission inspection if the
malfunction indicator lamp remains on. Contact your Lexus
dealer to check your vehicle's emission control system and
OBD (On-Board Diagnostics) system before taking your
vehicle for the inspection.
For details, see Emissions inspection and maintenance (I/M)
programsº on page 539.
(f) ABSº Warning Light
The light comes on when the ignition key is turned to the ONº
position. If the anti-lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the ABSº warning light is on (and the brake system
warning light is off), the following systems do not operate, but
the brake system still operates conventionally.

Anti-lock brake system
 Brake assist system
 Active traction control system
 Vehicle stability control system
 Downhill assist control system
 Hill-start assist control system
When the ABSº warning light is on (and the brake system
warning light is off), the anti-lock brake system does not
operate, so that the wheels will lock up during a sudden braking
or braking on slippery road surfaces.

 The light comes on while you are driving.
A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If the ABSº 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.
Either of the following conditions may occur, but do not
indicate a malfunction:
 The light may stay on for about 60 seconds after the ignition
key is turned to the ONº position. It is normal if it turns off
after a while.
 Depressing the brake pedal repeatedly may turn on the
light. It is normal if it turns off after a few seconds.

It is normal if they go out after a few seconds.
There is no problem when the VSC TRACº warning light
comes on when the brake actuator temperature becomes high.
If the light comes on while driving, the above mentioned
systems do 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 ONº.
 The warning light remains on after the ignition key is turned
to ONº.
 The warning light comes on while driving.
(k) KDSSº Warning Light (vehicles with kinetic
dynamic suspension system)
This light warns that there is a problem somewhere in the

Lexus dealer as soon as possible and have it checked.
(l) Discharge Warning Light
This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn off the
engine, and check for the cause. Look first at the engine drive
belt.
 If it is loose or broken, the generator will not charge the
battery properly.
 If the belt is O.K., there is a problem somewhere in the

HOW TO START THE ENGINE
Cranking hold function
Once you turn the ignition key to STARTº position and release
it, the cranking hold function continues to crank the engine in
ONº 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 STARTº 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 Pº. If you need to restart the engine
while the vehicle is moving, put the selector lever in Nº. 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 crankingº.
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
STARTº 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 startº on page 481.
NOTICE
Do not race a cold engine.
If the engine becomes difficult to start or stalls frequently, have the engine checked immediately.

STARTING AND DRIVING

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 Pº position when the
brake pedal is depressed with the ignition switch in ONº
position. ()
31PY039

The shift position is displayed beside the selector lever
and 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 Dº to 4º, engine braking will not be
enabled because the cru ise control is not cancelled. For
the operation to decrease the vehicle speed, see page
411.
