■ Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions.
■ When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning ( P. 264) may not be activated.
● Vehicles that cut in suddenly

■Automatic cruise co ntrol cancelation
Cruise control will stop maintaining the vehicle speed in any of the following
situations:
● Actual vehicle speed falls more than approximately 10 mph (16 km/h) below
the preset vehicle speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed is below approximately 25 mph (40 km/h).

◆VGRS (Variable Gear Ratio Steering)
Helps to adjust the wheel turning angle in accordance with the vehicle
speed and steering wheel movement.
◆Trailer Sway Control
Helps the driver to control trailer sw ay by selectively applying brake pres-
sure for individual wheels and reducing engine torque when trailer sway is
detected.
Trailer Sway Control is part of the VSC system and will not operate if VSC
turned off or experiences a malfunction.
The slip indicator light flashes to
indicate that the VSC/Trailer
Sway Control/Active TRAC/hill-
start assist control systems have
been engaged.
The stop lights and high mounted
stoplight turn on when the hill-start
assist control system or Trailer

■Automatic reactivation of Active TRAC, VSC and Trailer Sway Control
Turning the engine switch off after turning off the Active TRAC and VSC sys-
tems will automatically re-enable them.
■ Automatic Active TRAC reactivation
If only the Active TRAC system is turned off, the Active TRAC system will turn
on when vehicle speed increases.
■ Automatic Active TRAC, VSC and Tr ailer Sway Control reactivation
If the Active TRAC, VSC and Trailer Sway Control are turned off, the systems
will not turn on even when vehicle speed increases.
■ If the brake system overheats
The brake system may overheat. In this case, a buzzer will sound, and the
TRAC OFF indicator will flash, and Active TRAC and hill-start assist control
will be temporarily inoperable. In this event, stop the vehicle immediately in a
safe place, and allow the brake system to cool down sufficiently until the
TRAC OFF indicator go off. (There is no problem with continuing normal driv-
ing.)
■ Sounds and vibrations caused by th e Multi Terrain ABS, brake assist,
Active TRAC, VSC, Trailer Sway Control, hill-start assist control and
VGRS
● 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 above systems are
operating. 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.
• The brake pedal may pulsate slightly after the Multi Terrain ABS is acti-
vated.
• The brake pedal may move down slightly after the Multi Terrain ABS is activated.
■ Hill-start assist contro l is operational when
● The shift lever is in D or S.
● The brake pedal is not depressed.

driving at lower speeds.
● After the engine is restarted at less than -22 F (-30 C).
● If you disconnect the battery with the steering wheel turned, the center\
posi-
tion of the steering wheel could be slightly and temporary hanged. To initial-
ize the VGRS, drive for a short while.

WARNING
Any of the following conditions may result in an accident which could cause
death or serious injury:
■The Multi Terrain ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the Multi Terrain ABS is operating may exceed
that of normal conditions
The Multi Terrain ABS is not designed to shorten the vehicle’s stopping dis-
tance. Always maintain a safe distance from the vehicle in front of you,
especially in the following 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
■ Active TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the Active TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ If the hill-start assist control does not operate effectively
Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered in ice.
■ When Active TRAC, VSC and Tr ailer Sway Control are off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As there are systems to help ensure vehicle stability and driving force,
do not turn off Active TRAC, VSC and Trailer Sway Control unless neces-
sary.

WARNING
■When the VSC and Trailer Sway Control are activated
The slip indicator light flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator light flashes.
■
Replacing tires
Make sure that all tire s are of the same size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to
the specified tire pressure level.
The Multi Terrain ABS, Active TRAC, VSC and Trailer Sway Control will
not function correctly if differen t tires are fitted on the vehicle.
Contact your Toyota dealer for further information when replacing tires
or wheels.
■Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will
affect the driving assist systems, and may cause the system to malfunc-
tion.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations. Depending on many factors such as the conditions of the vehicle,
trailer, road surface, and driving environment, the Trailer Sway Control sys-
tem may not be effective. Refer to your trailer owner’s manual for informa-
tion on how to tow your trailer properly.
■ If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
●Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
● Begin releasing the accelerator pedal immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. ( P. 189)
