It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or that of the brake discs are exceeded.

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
activated with the following
two procedures.
●Press the VSC OFF switch
briefly.
At this time, the slip and AUTO
LSD indicators will come on.
●Stop the vehicle com-
pletely, and press the VSC
OFF switch for more than 3
seconds.
At this time, the slip, VSC OFF
and AUTO LSD indicators will
come on simultaneously.
To turn off the system, push
the switch again.

2-4. Using other driving systems
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 h eavily 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.
■TRAC (Traction Control) for 2WD models and 2WD mode on
4WD models
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 mode on 4WD
models
Maintains drive power and prevents the all wheels from spinning when
starting the vehicle or accelerating on slippery roads.

When driving
When VSC/TRAC/A-TRAC are operating
Vehicles with multi-information display If the vehicle is in danger of slip-
ping, or if the rear wheels (2WD
models and 2WD mode on 4WD
models) or all wheels (4WD
mode on 4WD models) spin, the
slip indicator flashes to indicate
that VSC/TRAC/A-TRAC have
been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
Vehicles without multi-information displayIf the vehicle is in danger of slip-
ping, or if the rear wheels (2WD
models and 2WD mode on 4WD
models) or all wheels (4WD
mode on 4WD models) spin, the
slip indicator flashes to indicate
that VSC/TRAC/A-TRAC have
been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.

232 2-4. Using other driving systems
To disable VSC and/or TRAC (2WD models and 2WD mode on 4WD models)

briefly.
The slip and AUTO LSD indica-
tors will come on.
The system is in TRAC off, AUTO
LSD on and VSC on mode.
Push the switch again to turn the
system back on.
■AUTO LSD mode
Stop the vehicle completely, and
press the VSC OFF switch for
more than 3 seconds, when the
system is in the TRAC OFF
mode.
The slip, VSC OFF and AUTO
LSD indicators will come on.
The system is in TRAC off, AUTO
LSD on and VSC off mode.
■VSC OFF mode
Stop the vehicle completely, and
press the VSC OFF switch for
more than 3 seconds, when the

driving systems
2
When driving
To disable VSC and A-TRAC (4WD mode on 4WD models)
If the vehicle gets stuck in fresh snow or mud, VSC may reduce
power from the engine to the wheels. You may need to turn VSC and
A-TRAC off to enable you to rock the vehicle in order to free it. Stop the vehicle completely, and
press the VSC OFF switch for
more than 3 seconds.
The slip and VSC OFF indicators
will come on.
The system is all off mode.
Push the switch again to turn the
system back on.
■Automatic reactivation of TRAC, A-TRAC and VSC
Turning the engine switch off after turning off the TRAC, A-TRAC and VSC
systems will automatically re-enable them.
■ Sounds and vibrations caused by the ABS, TRAC, A-TRAC, VSC 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.
• 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.
■ If the brake system overheats
TRAC or A-TRAC will cease operation and a buzzer will sound to alert the
driver. Stop the vehicle in a safe place. (There is no problem with continuing
normal driving.)
