When driving
nCruise control can be set when
lThe shift lever is in the “D” or “4”, “5” or “6” range of “S”.
lVehicle speed is more than approximately 25 mph (40 km/h).
nAccelerating
The vehicle can be accelerated normally. After acceleration, the set speed
resumes.
nAutomatic cruise control cancelation
The set speed is automatically canceled in any of the following situations.
lActual vehicle speed falls more than 10 mph (16 km/h) below the preset
vehicle speed.
At this time, the memorized set speed is not retained.
lActual vehicle speed is below 25 mph (40 km/h).
l
VSC is activated.
nCanceling and resuming regular acceleration
Cancel
Push the lever towards you to
cancel cruise control.
The speed setting is also can−
celed when the brakes are
applied.
Resume
To resume cruise control and
return to the set speed, push
the lever up.

nThe fourwheel drive control switch can be operated when
lThe “ENGINE START STOP” switch is in IGNITION ON mode.
lThe shift lever is in the “N” position.
lThe vehicle is stopped completely.
nAdvice for driving on slippery roads in “L4” (low speed position)
lIf you shift the four−wheel drive control switch to “L4” and the shift lever to
the “2” range of “S” while driving in steep off−road areas, the output of the
brake can be controlled effectively by the active traction control system,
which assists the driver to control the driving power of 4 wheels.
lUse the “1” range of “S” of the shift lever for maximum power and traction
when your wheels get stuck or when driving down a steep incline. In the
following cases, the output of the brake can be controlled by the active
traction control system if the engine speed is under 3,000 rpm (normally
under 3,000 rpm when the wheels get unstuck).
The four−wheel drive control switch is in the “L4” position and the shift
lever is in the “1” range of “S” or the shift lever is in “D” or “S” with the
transmission downshifted to first gear.
The four−wheel drive control switch is in the “L4” position and the shift
lever is in the “R” position.
nThe center differential lock/unlock button can be operated when
lThe “ENGINE START STOP” switch is in IGNITION ON mode.
lThe vehicle speed is less than 60 mph (100 km/h).
nLocking/unlocking the center differential
lWhen the center differential is locked, VSC (vehicle stability control) is
automatically turned off. (The center di
fferential lock and “VSC OFF” indi−
cator lights come on.)
lIf the operation is not completed, the center differential lock indicator
blinks. If the indicator light does not turn off when unlocking the center
differential, drive straight ahead while accelerating or decelerating, or
drive in reverse.
lIf the center differential lock/unlock is not completed within 5 seconds
while the cruise control system is on, cancel the cruise control system.

When driving
Driving assist systems
To help enhance driving safety a nd 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.
nMulti Terrain ABS (Antilock Brake System)
Restrains the vehicle from slipping when driving on sand, gravel, dirt,
mud, snow, ice or slick road surfaces, or in the event of sudden brak−
ing.
nBrake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
nVSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
nActive TRAC (Traction Control)
Maintains drive power and prevents the 4 wheels from spinning when
starting the vehicle or accelerating on slippery roads.
nHillstart assist control
Helps prevent the vehicle from rolling backwards when starting on an
incline or slippery slope. It operates for approximately 5 seconds at
maximum.
nKDSS (Kinetic Dynamic Suspension System)
KDSS enhances ride comfort and handling response by using a
hydraulic control system to control the suspension stabilizer bars in
response to road surface and driving conditions during cornering or off−
road driving.
nPCS (PreCollision System) (if equipped)

202 2−4. Using other driving systems
When the VSC/Active TRAC/hillstart assist control systems are
operating
If the vehicle is in danger of slip−
ping, rolling backwards when
starting on an incline, or if the
rear wheels spin, the slip indica−
tor light flashes to indicate that
the VSC/ActiveTRAC/hill−start
assist control systems have
been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
The stop lights and high mounted
stoplight turn on when the hill−
start assist control system is
operating.

To disable Active TRAC and/or VSC system
If the vehicle gets stuck in fresh snow or mud, Active TRAC and VSC
system 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.
n
Turning off Active TRAC
Quickly push and release the
button to turn off Active TRAC.
The slip indicator light should

Push the button again to turn the
system back on.
nTurning off Active TRAC and VSC
Push and hold the button for
more than 3 seconds while the
vehicle is stopped to turn off
Active TRAC and VSC.
The slip indicator light will come

nAutomatic reactivation of Active TRAC and VSC
Turning the “ENGINE START STOP” switch off after turning off the Active
TRAC and VSC systems will automatically re−enable them.
nAutomatic Active TRAC reactivation
If only the Active TRAC system is turned off, the Active TRAC system will
turn on when vehicle speed increases.
nAutomatic Active TRAC and VSC reactivation
If the Active TRAC and VSC systems are turned off, the systems will not turn
on even when vehicle speed.
