■Automatic cruise control cancellation
Cruise control is automatically cancelled
in any of the following situations.
• Actual vehicle speed is more than 10 mph
(16 km/h) below the preset vehicle
speed.
• Vehicle speed is less than 25 mph (40 km/h).
• The slip indicator light blinks and a warning tone sounds.
■If the cruise control indicator light flashes
Turn the ON-OFF switch off once, and then reactivate the system. There may be a
malfunction in the cruise control system if the indicator light does not come on,
flashes again or goes out after it comes on. Have the vehicle inspected by your
Lexus dealer.
CAUTION
■To avoid inadvertent cruise control activation
Keep the ON-OFF switch off when not in use.
■Locations unsuitable for cruise control
●Do not use cruise control in any of the following situations.
Doing so may result in control of the v
ehicle being lost and may cause an acci -
dent.
• In heavy traffic.
• On roads with sharp bends.
• On slippery roads, such as th o
se covered with ice or snow.
• On steep hills.
• On winding roads.

2-4. Using other driving systems
■Setting vehicle speed
Settings can be made when the vehicle
is traveling above 28 mph (45 km/h).
■Unsuitable conditions
You cannot set the speed in the following conditions:
• When the selector lever is in a position other than D, 4, 5, or 6.
• When driving in adverse weather conditions.
■Automatic cruise control cancellation
In the following cases, the preset speed is can ce
lled. If the system is restored, cruise
control enters the ready mode.
• The slip indicator light blinks and a warning tone sounds.
• The anti-lock braking system activates.
• Foreign matter adheres to the sensor.
• The driving pattern selector sw it
ch is set to “SNOW” mode.
• The wipers are operated at high speed (radar), or either high or low speeds (l
aser). This includes high and low speed operation with the wiper lever in the
AUTO position.
• The vehicle’s speed falls below 25 mph (40 km/h). In this case, you must apply th
e brakes manually to slow the vehicle.
If the preset speed automatically cancels out for other than the above reasons, the
sy
stem may have malfunctioned. Do not operate the dynamic radar/laser cruise
control. You may continue driving, howe ver have your vehicle checked by your
Lexus dealer at the earliest opportunity.

When driving
To disable VSC and TRAC
If the vehicle gets stuck in fresh snow or mud, VSC and TRAC may
reduce power from the engine to the wheels. You may need to turn VSC
and TRAC off to enable you to rock the vehicle in order to free the vehi-
cle.
Push the button to turn off VSC
and TRAC.
The TRAC OFF indicator light
turns on.
Push the button again to turn the
sy

■Operating sounds and vibrations caus ed by the ABS, VSC & TRAC systems
●A sound may be heard from the engine compartment 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 ABS, VSC and TRAC sys -
tems are operating. None of these indicates that a malfunction has occurred.
• A sound may be heard.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly while the ABS is activated.
• The brake pedal may move forward slightly after the ABS is activated.
■Failure warning for VSC or TRAC system
If an error in the VSC or TRAC systems is
detected, the master warning light and
TRAC OFF indicator light comes on, a warning tone sounds. (P.334 )

2-4. Using other driving systems
CAUTION
Any of the following conditions may result in-an accident which could cause death
or serious injury:
■The ABS may not operate effectively when:
●The limits of tire gripping performance have been exceeded.
●If the vehicle hydroplanes while driving at high speed while the road is wet or
slick.
■Stopping distance when the ABS is activated will exceed that of normal condi -
tions
The ABS is not designed to shorten the v
ehicle’s stopping distance. Always main -
tain a safe distance between you and the vehicle in front of you, particularly in the
fo
llowing situations.
• When driving on dirt, gravel or snow-covered roads
• When driving with tire chains
• When driving over bumps in the road
• When driving over roads with potholes or uneven roads
• When towing a trailer
■TRAC may not operate effectively when:
Directional control and power may not be ac hi
evable while driving on slippery road
surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where control and power may be lost.
■When the slip indicator flashe s and a warning buzzer sounds
This situation occurs immediately before VSC is activated. Always drive carefully.
R
eckless driving may cause an at the recommended level.
Exercise particular care when an indicator light flashes and a buzzer sounds.
■Replacing tires
Ensure that all tires are the same size an d
brand, have the same tread pattern, and
that the level of tire pressure is at the recommended level.
The ABS and VSC systems may not operate no rmal
ly if different tires are installed
to the vehicle.
Contact your Lexus dealer for further info rmati
on when replacing tires or wheels.

CAUTION
■Pre-collision system limitations
●The Pre-Collision System is designed to help reduce the crash speed and dam-
age in certain frontal collisions only. It is not a collision avoidance system and is
no
t a substitute for safe and attentive driving. System effectiveness depends on
many factors, such as speed, dr iver input and road conditions.
●The sensor is able to detect objects in front of the vehicle within 10 degrees on
either side. If the object is out of range, or there is little to no millimeter wave
reflection, the sensor will not detect the object.
●Even if the system is operative in a collisio n, unless the seat belts are worn and the
brake pedal is depressed, the pre-collision seat belts and brake assist system will
operate.
■Failure Warning
If an error is detected, the master warn i
ng light comes on, a warning tone sounds
and the following warning message appears on the multi-information display.
