When driving
■Dynamic laser cruise control can be set when
●The shift lever is in the D or range 4 or higher of S has been selected.
● Vehicle speed is above approximately 30 mph (50 km/h).
■ Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-
vehicle distance control mode has been used. The mode also cannot be
switched from constant speed control to vehicle-to-vehicle distance control
mode. Turn the system off by pressing the ON-OFF button, and turn it on
again.
■ Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed
resumes. However, during vehicle-to-vehicle distance control mode, the
vehicle speed may decrease below the set speed in order to maintain the
distance to the vehicle ahead.
■ Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations:
●Actual vehicle speed falls below approximately 25 mph (40 km/h)
● VSC is activated
● The sensor cannot operate correctly because it is covered in some way.
*
●The windshield wipers are operating at high or low speed.*
●The operation cannot be switched for 5 seconds or more after operating
the front wheel drive control switch or the center differential lock switch.
(4WD models)
*: Vehicle-to-vehicle distance control driving must be reset by pressing the
ON-OFF button again.
If vehicle-to-vehicle distance control driving is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following sit-
uations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h)
below the set vehicle speed
At this time, the memorized set speed is not retained.
● Vehicle speed falls below approximately 25 mph (40 km/h)
● VSC is activated
● The operation cannot be switched for 5 seconds or more after operating
the front wheel drive control switch or the center differential lock switch.
(4WD models)
■ Laser radar sensor
■ Warning lights, messages and buzzers for dynamic laser cruise control
Warning lights, messages and buzzers are used to indicate a system mal-
function or to inform the driver of the need for caution while driving.
(P. 644)
■ Certification
Always keep the sensor clean to ensure
that the vehicle-to-vehicle distance con-
trol operates properly. (Some obstruc-
tions, such as snow, ice and plastic
objects, cannot be detected by the
obstruction sensor.)
Dynamic laser cruise control is canceled
if an obstruction is detected.
This product is a class I laser product complied with 21C.F.R part 1040.10
and 1040.11.

When driving
AUTO LSD system
The AUTO LSD system aids traction by using the traction control
system to control engine performance and braking when one of the
rear wheels begins to spin.
The system should be used only wh en one of the rear wheels spin-
ning occurs in a ditch or rough surface.
■ System operation
The system can be used on 2W D models and in 2WD mode on
4WD models.
The system is activated when dr iving at a speed under 62 mph
(100 km/h).
The AUTO LSD system will be ac tivated with the following two
procedures.
Press the VSC OFF switch
briefly.
At this time, the AUTO LSD
indicator will come on.
To turn off the system, push
the switch again.
Stop the vehicle completely,
and press the VSC OFF
switch for more than 3 sec-
onds.
At this time, VSC OFF and
AUTO LSD indicators will
come on simultaneously.
To turn off the system, push
the switch again.

When driving
Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavi ly when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes 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 detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake
pressure 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 is turned off or experiences a malfunction.
■ TRAC (Traction Control) for 2WD
Maintains drive power and prevents the rear wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■A-TRAC (Active Traction Control) for 4WD
Maintains drive power and prevents all wheels from spinning when
starting the vehicle or accelerating on slippery roads.

256 2-4. Using other driving systems
When VSC/Trailer Sway Control/TRAC/A-TRAC are operatingIf the vehicle is in danger of slip-
ping, or if the rear wheels (2WD
models) or all wheels (4WD
models) spin, the slip indicator
flashes to indicate that
VSC/Trailer Sway Control/TRAC/
A-TRAC have been engaged.
To disable VSC, Trailer Sway Control and/or TRAC (2WD models
and 2WD mode on 4WD models)If the vehicle gets stuck in fresh snow or mud, VSC, Trailer Sway
Control and/or 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.
■ TRAC OFF mode
Press the VSC OFF switch
briefly.
The AUTO LSD indicator will
come on.
The system is in TRAC off, AUTO
LSD on and VSC, Trailer Sway
Control on mode.
Push the switch again to turn the
system back on.

■Automatic reactivation of TRAC, A-TRAC, VSC and Trailer Sway Con-
trol
Turning the engine switch off after turning off the TRAC, A-TRAC, VSC and
Trailer Sway Control systems will automatically re-enable them.
■ Automatic A-TRAC reactivat ion (A-TRAC OFF mode)
With A-TRAC OFF mode, TRAC OFF i ndicator turn on. The A-TRAC system
will turn on when the vehicle speed increases.
■ When the TRAC OFF indicator com es on even if the VSC OFF switch
has not been pressed
TRAC cannot be operated. Contact your Toyota dealer.
■ Sounds and vibrations caused by the ABS, TRAC, A-TRAC, VSC,
Trailer Sway Control and brake assist system
● A sound may be heard from the engine compartment when the engine is
started and 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.
