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)
Maintains drive power and prevents the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■AUTO LSD function (2WD models)
The AUTO LSD function is activated when the system is in TRAC off
mode. It operates when one of the drive wheels is spinning, such as
when the wheel is spinning freely on ice or mud. The system applies
the brakes to the spinning wheel and transfers some of the torque to
the other wheel to secure drive power.
■Active Torque Control 4W D system (4WD models)
Automatically switches from front-wheel drive to four-wheel drive
(4WD) according to the driving conditions, helping to ensure reliable
handling and stability. Examples of conditions where the system will
switch to 4WD are when cornering, going uphill, starting off or acceler-
ating, and when the road surface is slippery due to snow, rain, etc.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

When driving
To disable TRAC and/or VSC (4WD models)
If the vehicle gets stuck in fresh snow or mud, TRAC and VSC 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.
■ Turning off TRAC
Quickly push and release the
button to turn off TRAC.
The “TRAC OFF” indicator light
should come on.
Push the button again to turn the
system back on.
■Turning off TRAC and VSC
Push and hold the button while
the vehicle is stopped to turn off
TRAC and VSC.
The “TRAC OFF” and VSC OFF
indicator lights should come on.
Push the button again to turn the
system back on.

188 2-4. Using other driving systems
■Automatic reactivation of TRAC and VSC
Vehicles without smart key system
Turning the engine switch OFF after turning off the TRAC and VSC systems
will automatically re-enable them.
Vehicles with smart key system
Turning the “ENGINE START STOP” switch OFF after turning off the TRAC
and VSC systems will automatically re-enable them.
■ Automatic TRAC reactivation
2WD models
If only the TRAC system is turned off, the TRAC system will be reactivated
while vehicle speed is increased. 4WD models
If only the TRAC system is turned off, the TRAC system will turn on when
vehicle speed increases.
■ Automatic TRAC and VSC reactivation
If the TRAC and VSC systems are turned off, the systems will not turn on
even when vehicle speed increases.
■ Sounds and vibrations caused by the ABS, TRAC and VSC
●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 indi-
cate 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 when the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ When the AUTO LSD function operates continuously
The brake actuator may overheat. In that case, the system will stop the
AUTO LSD function, a buzzer will sound and the slip indicator will stay on
steady. Refrain from using the AUTO LSD function until the slip indicator
goes off. (There is no problem with continuing driving normally.)

2-4. Using other driving systems
Four-wheel drive lock switch (4WD models)
■Four-wheel drive lock mode can be operated when
Vehicles without smart key system
The engine switch is in the “ON” position. Vehicles with smart key system
The “ENGINE START STOP” switch is in IGNITION ON mode.
■ Four-wheel drive lock mode
●Four-wheel drive lock mode is canceled when the brakes are applied to
ensure the ABS and VSC systems operate effectively.
● Four-wheel drive lock mode is canceled when the vehicle speed exceeds
25 mph (40 km/h).
Four-wheel drive lock mode can be used when a large amount of
drive power needs to be applied to all the wheels, such as when the
vehicle gets stuck in mud and you need to free it.
Press the switch.
The torque of the engine is dis-
tributed to the rear wheels to
the maximum extent possible
in accordance with driving con-
ditions.
Pressing the switch again can-
cels four-wheel drive lock
mode and returns the Active
Torque Control 4WD system to
normal mode. (P. 184)

Dinghy towing
NOTICE
■To avoid serious damage to your vehicle
■ To prevent causing serious damage to the transmission and Active
Torque Control 4WD system (4WD models)
Your vehicle is not designed to be dinghy towed (with 4 wheels on
the ground) behind a motor home.
Do not tow your vehicle with 4 wheels on
the ground.
CTN25AN019
2WD models: Never tow this vehicle from
the rear with the front wheels on the
ground. This may cause serious damage
to the transmission.
4WD models: Never tow this vehicle with
any of the wheels on the ground. This
may cause serious damage to the trans-
mission and Active Torque Control 4WD
system.
