188 Driving and Operating
Mode Activation
To activate each mode, turn the MODE knob
on the center console in either direction.
Mode Descriptions
Normal Mode :Use this mode for normal
city and highway driving. This setting
provides balance between comfort and
handling. This is the setting the vehicle will
default to every time it is started, unless
Tow/Haul mode has been activated within
the last four hours. See “Tow/Haul Mode”
later in this section.
7Off-Road Mode : Use this mode only
for off-road recreational driving. Off-Road
Mode should be used to improve driving at
moderate speeds on grass, gravel, dirt,
unpaved roads, or deep snow. If equipped,
this mode modifies steering, pedal map,
transmission shift points, Four-Wheel Drive
AUTO, Antilock Brake System (ABS),
Electronic Stability Control (ESC), and
Traction Control System (TCS) performance.
Off-Road mode optimizes ABS performance
to decrease stopping distances for
deformable or loose surfaces.
For more information on off-road driving,
see Off-Road Driving 0153.
gTerrain Mode : Use this mode when
traveling on challenging road conditions at
lower speeds, such as a two-track, difficult
terrain, or rock crawling. This mode allows
for one pedal driving which automatically
applies the vehicle brakes when the
accelerator pedal position is decreased. This
can also be used for pulling a boat out of
the water on a trailer. Terrain mode functions when the vehicle is
in 4
mor 4n, and in D (Drive), R (Reverse),
or L (Low). When the vehicle is in L (Low),
the lower the gear, the more aggressive the
braking.
The following are the braking calibrations
for each gear:
.L1: Most aggressive
.L2 or D (Drive): Moderately aggressive
.L3–L8: Least aggressive
The vehicle uses more aggressive braking
calibrations for the above drive states when
it is in 4
ncompared to 4m.
When in Terrain Mode, the vehicle shifts
automatically, but holds a lower gear longer
to maximize engine torque. This is done so
vehicle momentum is not lost when driving
up a hill. This mode modifies steering, pedal
map, transmission shift points, ABS, ESC, and
TCS performance for better control at lower
speeds and over rough terrain.

Driving and Operating 189
Do not lock the front axle while in Terrain
Mode when driving on slippery roads. If the
front axle is locked while in Terrain mode,
the ABS warning light appears indicating
that ABS is off, which may result in the
wheels locking during deceleration. See
Locking Front Axle0192.
When the vehicle comes to a stop on an
upward grade, Automatic Vehicle Hold is
engaged until the accelerator pedal is
pressed. Start/Stop and cruise control are
disabled in Terrain Mode.
Active Braking will be engaged while in
Terrain Mode when vehicle speed is less
than 48 km/h (30 mph). Terrain mode will
not operate at speeds exceeding 80 km/h
(50 mph).
In D (Drive) and 4
n, moderate braking is
applied until the vehicle comes to a stop. In
D (Drive) and 4
m, moderate braking is
applied until the vehicle is at idle speeds. In
4
nor 4mand L1 or L2, the braking is applied
until the vehicle comes to a stop. In 4
nor
4
mand in L3-L8, the braking is applied until
the vehicle is at idle speeds. Terrain Mode will automatically exit to
Normal Mode if the brake or transmission
temperatures become too hot, the Electronic
Parking Brake (EPB) becomes inoperable, the
vehicle cannot perform braking or vehicle
hold, or if the transfer case is shifted out of
4
mor 4n.
For more information on off-road driving,
see Off-Road Driving 0153 and
Hill and Mountain Roads 0159.
_Tow/Haul Mode : Use this mode
when towing heavy loads to provide
increased performance and vehicle control.
Tow/Haul mode adjusts steering, pedal map,
transmission shift points, ABS, ESC, TCS
performance, and uses Trailer Sway
Control (TSC).
If equipped with only Normal and Tow/Haul
modes, there may be a Tow/Haul mode
button on the drive mode control knob or
center stack. Press
_to enter the mode. If the vehicle is turned off with Tow/Haul
Mode active and then restarted within four
hours or less, Tow/Haul will remain active.
Otherwise, the vehicle will start in
Normal Mode.
For more information on Tow/Haul mode,
see
Towing Equipment 0236.
9BAJA Mode (AT4x) : Use this mode for
off-road recreational driving at higher
speeds. This mode is not designed for
on-road usage. Hard packed sand, dirt, and
gravel are examples of surfaces that support
high speed driving. Baja mode can be
activated in all transfer case states.
Baja mode adjusts the steering, pedal map,
Four-Wheel Drive Auto, transmission shift
points, ABS, ESC, and TCS performance in
order to maximize response at higher vehicle
speeds. If enabled, the rear lockers will
remain locked at all speeds.
Baja mode optimizes ABS performance to
decrease stopping distances for deformable
or loose surfaces.

Limited-Slip Differential
If equipped, the limited-slip differential can
give more traction on snow, mud, ice, sand,
or gravel. It works like a standard axle most
of the time, but when traction is low, thisfeature allows the drive wheel with the
most traction to move the vehicle. For
vehicles with the limited-slip differential,
driven under severe conditions, the rear axle
fluid should be changed. See
Maintenance
Schedule 0328.
Locking Rear Axle
If equipped, the locking rear axle can give
the vehicle additional traction from the rear
wheels when traveling in off-road situations
such as mud, snow, steep hills, and uneven
terrain.

Caution
If you try to lock the axle while the
vehicle is stuck and the tires are spinning,
the vehicle’s drivetrain could be damaged.
The repairs would not be covered by the
vehicle warranty. Always lock the axle
before attempting situations and/or
navigating terrain that could cause the
vehicle to become stuck.
Caution
If the vehicle’s axle is locked while driving
on pavement, the drivetrain could be
damaged. Repairs would not be covered
by the vehicle warranty. Do not use the
locking axle on pavement.
{Warning
Driving on pavement with a locked front
axle may cause reduction to or complete
loss of steering assist, which could result
in serious injury, death, or property
damage. Do not use the locking front
axle on pavement.Before the front axle can be locked, the
transfer case must be in 4
n.
To lock the front axle, press the front/rear
axle locking switch. If it was not already
locked, the rear axle will lock first followed
by the front axle
To lock the front and rear axles: 1. Place the transfer case in 4
n. This is the
only mode that allows the front axle to
lock. See Four-Wheel Drive 0179 for
more information regarding the transfer
case and four-wheel drive low operation.
2. Press the front/rear axle locking switch with the vehicle stopped or moving less
than 30 km/h (20 mph).
3. Wait for the light in the switch to stop flashing and remain illuminated to show
that the front axle is locked. Engagement
of the front axle lock will disable the
Antilock Brake System (ABS) and
illuminate the ABS warning light. The
wheels may lock up in this condition
when decelerating from either applying
the brake pedal or automatic braking in
Terrain Mode. See Driver Mode Control
0 187. If this occurs, press the accelerator pedal to unlock the wheels. Hill Decent
Control (HDC) will also be disabled when
the front axle lock is engaged.
If the electronic locking differential has
difficulty engaging, release the
accelerator pedal.
To unlock the front axle, perform one of the
following actions:
‐ Press the rear axle locking switch. The
front axle unlocks and the rear axle
remains locked. See Locking Rear Axle
0 191.
‐ Press the front/rear axle locking switch.
The front and rear axles both unlock.

194 Driving and Operating
that ABS is off, which may result in the
wheels locking during deceleration. See
Driver Mode Control0187.
If HDC was enabled prior to axle lock, it will
be automatically enabled when the locking
front axle is disengaged.
After pressing the switch to unlock the axle,
it may remain locked due to torque in the
driveline. The axle is more easily unlocked
by turning the steering wheel to the right
and to the left while traveling at a low
speed.
Cruise Control
With cruise control a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your foot on
the accelerator. Cruise control does not work
at speeds below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous where
you cannot drive safely at a steady
speed. Do not use cruise control on
winding roads or in heavy traffic. (Continued)
Warning (Continued)
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
If the cruise control is being used and the
Traction Control (TCS) system or StabiliTrak/
Electronic Stability Control (ESC) begins to
limit wheel spin, the cruise control will
automatically disengage. See Traction
Control/Electronic Stability Control 0185. If a
collision alert occurs when cruise control is
activated, cruise control is disengaged. See
Forward Collision Alert (FCA) System 0215.
When road conditions allow you to safely
use it again, cruise control can be turned
back on.
If equipped with Hill Descent Control (HDC),
cruise control will disengage if HDC is Active.
If the brakes are applied, the cruise control
disengages.

196 Driving and Operating
Erasing Speed Memory
The cruise control set speed is erased from
memory if
5is pressed or if the ignition is
turned off.
Adaptive Cruise Control (Camera)
If equipped, Adaptive Cruise Control (ACC)
allows the cruise control set speed and
following gap to be selected. Read this
entire section before using this system. The
following gap is the following time between
your vehicle and a vehicle detected directly
ahead in your path, moving in the same
direction. If no vehicle is detected in your
path, ACC works like regular cruise control.
ACC uses a windshield mounted front
camera sensor.
If a vehicle is detected in your path, ACC can
apply acceleration or limited, moderate
braking to maintain the selected following
gap. To disengage ACC, apply the brake.
If ACC is controlling the vehicle speed when
the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control (ESC)
system activates, ACC may automatically
disengage. See Traction Control/Electronic
Stability Control 0185. When road
conditions allow ACC to be safely used, ACC can be turned back on. Disabling the TCS or
StabiliTrak/ESC system will disengage and
prevent engagement of ACC.
ACC can reduce the need for you to
frequently brake and accelerate, especially
when used on expressways, freeways, and
interstate highways. When used on other
roads, you may need to take over the
control of braking or acceleration more
often.
{Warning
ACC has limited braking ability and may
not have time to slow the vehicle down
enough to avoid a collision with another
vehicle you are following. This can occur
when vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver”
later in this section.
Complete attention is always required
while driving and you should be ready to
take action and apply the brakes. See
Defensive Driving 0151.
{Warning
ACC will not detect or brake for children,
pedestrians, animals, or other objects.
Do not use ACC when:
.On winding and hilly roads or when
the sensors are blocked by snow, ice,
or dirt. The system may not detect a
vehicle ahead. Keep the entire front of
the vehicle clean.
.Visibility is poor due to rain, snow,
fog, dirt, insect residue, or dust; when
other foreign objects obscure the
camera and/or radar; or when the
vehicle in front or oncoming traffic
causes additional environmental
obstructions, such as road spray. ACC
performance is limited under these
conditions.
.On slippery roads where fast changes
in tire traction can cause excessive
wheel slip.
.With extremely heavy cargo loaded in
the cargo area or rear seat, or when
the vehicle is loaded in excess of load
limits. See Vehicle Load Limits 0162.
