AUTO LSD system
The system can be used on 2WD models and in 2WD mode on 4WD
models.
The system is activated when driving at a speed under 62 mph (100
km/h).
The AUTO LSD system will be activa ted with the following two proce-
dures.
Press the VSC off switch briefly.
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 seconds.
The VSC off and “AUTO LSD” indi-
cators will come on.
To turn off the system, push the
switch again.
The AUTO LSD system aids trac tion by using the traction con-
trol system to control engine performance and braking when
one of the rear wheels begins to spin.
The system should be used only when one of the rear wheels
spinning occurs in a ditch or rough surface.
System operation

2324-5. Using the driving support systems
If the rear wheels spin, the slip
indicator flashes to indicate that
the AUTO LSD system has con-
trolled the spinning of the rear
wheels.
■If the engine is turned off and restarted
The AUTO LSD system and the indicators are automatically turned off.
■ If the brake system overheats
The AUTO LSD system will cease operation, and the slip indicator will
change from flashing to being on continuously to alert the driver. Stop the
vehicle in a safe place. (There is no problem with continuing normal driving.)
The system will be automatically restored after a short time.
When the AUTO LSD system is operating
CAUTION
■To avoid an accident
● Do not use the AUTO LSD system in conditions other than the above.
A much greater steering effort and more careful cornering control will be
required.
● Do not drive with the AUTO LSD system continuously turned on.

Driving assist systems
◆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 system is turned off or experiences a malfunction.
◆TRAC (Traction Control) for 2WD models and 2WD mode on
4WD models
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆A-TRAC (Active Traction Control) for 4WD mode on 4WD mod-
els
Maintains drive power and prevents all wheels from spinning when
starting the vehicle or accelerating on slippery roads.
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

2344-5. Using the driving support systems
The slip indicator light will flash
while the TRAC/VSC/A-TRAC/
Trailer Sway Control systems are
operating.
If the vehicle gets stuck in fresh snow or mud, VSC/Trailer Sway Con-
trol/TRAC systems 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.
The “AUTO LSD” indicator will
come on.
The system is in TRAC off and
AUTO LSD, VSC, Trailer Sway
Control on mode.

played on the multi-information disp lay showing that “TRACTION CON-
TROL OFF” has been disabled 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, brake assist, VSC, TRAC, A-
TRAC and Trailer Sway Control systems
●A sound may be heard from the engine compartment when 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
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 ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ Reactivation of the TRAC/VSC/A-T RAC/Trailer Sway Control systems
Even after the TRAC/VSC/A-TRAC/Trailer Sway Control systems have been
turned off, turning the engine switch off and then on again will automatically
reactivate the TRAC/VSC/A-TRAC/Trailer Sway Control systems.
■ Reactivation of the TRAC system linked to vehicle speed
When only the TRAC system is turned off, the TRAC system will turn on
when vehicle speed increases. However, when both TRAC/VSC systems are
turned off, the systems will not turn on even when vehicle speed increases.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures. • Engine oil
• Engine coolant
• Washer fluid
● Have a service technician ins pect the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
Perform the following accordin g to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Al ways drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.
