1-6. Theft deterrent system
Tilt sensorThe tilt sensor detects changes in vehicle inclination, such as when the
vehicle is towed away.
This system is designed to deter and p revent vehicle theft but does not
guarantee absolute security against all tilts.
The tilt sensor can be canceled using the cancel switch.
Canceling the tilt sensor
Remove the key from the ignition
switch and press the tilt sensor
cancel switch in the glove box.
To set the alarm with the tilt sensor
disabled, the alarm must be set
within 5 minutes after canceling
the sensor.
The tilt sensor will revert to on each
time the ignition switch is turned to
the “ON” position.
To cancel the tilt sensor, perform the necessary procedure each time
canceling the sensors is desired.

When driving
■Warning lights
Warning lights inform the driver of ma lfunctions in any of the vehicle’s
systems. ( P. 312)
*1: These lights turn on when the ignition switch is turned to the “ON” position
to indicate that a system check is being performed. They will turn off after the
engine is started, or after a few seconds. There may be a malfunction in a sys-
tem if a light does not come on, or if th e lights do not turn off. Have the vehi-
cle inspected by your Lexus dealer.
*2: The display flashes to indicate that the engine oil temperature is too high.
*3: These displays flash to indicate that the engine coolant temperature is too
high.

CAUTION
■If a safety system warning light does not come on
Should a safety system lig ht such as the ABS or SRS warning light not come on
when you start the engine, this could mean that these systems are not available to
help protect you in an accident, which could result in death or serious injury. Have
the vehicle inspected by your Lexus dealer immediately if this occurs.

2-4. Using other driving systems
Driving assist systems
To help enhance driving safety and performance, the following systems oper-
ate automatically in response to various driving situations. Be aware, however,
that these systems are supplementary and should not be relied upon too
heavily when operating the vehicle.
■ ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the br akes are applied suddenly, or if the
brakes are applied while driving on a slippery road surface.
■ Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system de tects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces.
■ TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■Hill-start assist control
Helps to reduce the vehicle’s rolling backward distance when starting on an
incline or slippery slope.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel.
■VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, VSC, TRAC, and hill-
start assist control systems.
Helps to maintain vehicle stability when swerving on slippery road surfaces
by controlling the brakes and engine output.
When switched to SPORT driving mode, the control characteristics of the
VDIM system are altered.

When driving
When the ABS/VSC/TRAC/hill-start assist control systems are operating
The slip indicator flashes to indi-
cate that the ABS/VSC/TRAC/
hill-start assist control systems are
operating.
The stop lights and high mounted
stoplight turn on when the hill-start
assist control system is operating.
Disabling the VSC/TRAC systemsIf the vehicle gets stuck in fresh snow or mud, VSC/TRAC may reduce
power from the engine to the wheels. You may need to turn the system off
to enable you to rock the vehicle in order to free it.
Press the switch to turn off VSC
and TRAC.
The VSC off indicator light and
“TRAC OFF” indicator light should
come on.
Press the switch again to turn the
systems back on.

2-4. Using other driving systems
■Hill-start assist control operation conditions
●The vehicle rolls backward.
●A forward gear is selected.
●The brake pedal is not depressed.
■Automatic reactivation of the VSC/TRAC systems
If the VSC/TRAC systems are turned off, re-starting the engine will automatically
reactivate them.
■Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC and hill-start
assist control systems
●A sound may be heard from the engine compartment if the brake pedal is
depressed repeatedly when the engine is started or just after the vehicle begins
to move. This sound does not indicate that a malfunction has occurred in any of
these systems.
●Any of the following conditions may occur when the above systems are operat-
ing. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
■EPS operation sound
When the steering wheel is operated, a motor sound may be heard. This does not
indicate a malfunction.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from over-
heating when there is frequent steering in put over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from excessive
steering input or stop the vehicle and turn the engine off. The EPS system should
return to normal within 10 minutes.
■If the slip indicator comes on
It may indicate a malfunction in the VSC, TRAC or hill-start assist control system.
Contact your Lexus dealer.

When driving
CAUTION
■The ABS does not operate effectively when
●Tires with inadequate gripping ability are used.
●The vehicle hydroplanes while driving at high speed on wet or slick roads.
■Stopping distance when the ABS is operating will exceed that of normal condi-
tions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you in the following situations:
●When driving on dirt, gravel or snow-covered roads
●When driving over bumps in the road
●When driving over roads with potholes or roads with uneven surfaces
■TRAC may not operate effectively in some conditions
Directional control and power may not be ac hievable while driving on slippery road
surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■Hill-start assist control does not operate effectively in some conditions
Do not overly rely on the hill-start assist co ntrol. The hill-start assist control may not
operate effectively depending on the grad e of incline and on roads covered with
ice.
■If the slip indicator flashes while driving
The slip indicator flashes to indicate that ABS, VSC, TRAC or hill-start assist con-
trol is operating. Always drive carefully. Reckless driving may cause an accident.
Exercise particular care when the indicator light flashes.
■When the VSC/TRAC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to help ensure vehicl e stability and driving force by automati-
cally controlling the brakes and engine ou tput, do not turn the VSC/TRAC systems
off unless necessary.

2-4. Using other driving systems
CAUTION
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire
inflation pressure level. ( P. 366)
The ABS, VSC and TRAC systems will not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further info rmation when replacing tires or wheels.
■Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect the driv-
ing assist systems, and may cause a system to malfunction.
