2. Shift into P (Park) and then restart theengine.
.If driving uphill when the vehicle
stalls, shift to R (Reverse), release the
parking brake, and back
straight down.
.Never try to turn the vehicle around.
If the hill is steep enough to stall the
vehicle, it is steep enough to cause it
to roll over.
.If you cannot make it up the hill,
back straight down the hill.
.Never back down a hill in N (Neutral)
using only the brake. The vehicle can
roll backward quickly and you could
lose control.
.If driving downhill when the vehicle
stalls, shift to a lower gear, release
the parking brake, and drive straight
down the hill.
3. If the vehicle cannot be restarted after stalling, set the parking brake, shift into
P (Park), and turn the vehicle off.
3.1. Leave the vehicle and seek help.
3.2. Stay clear of the path the vehicle would take if it rolled downhill.
{Warning
Getting out of the vehicle on the
downhill side when stopped across an
incline is dangerous. If the vehicle rolls
over, you could be crushed or killed.
Always get out on the uphill side of the
vehicle and stay well clear of the
rollover path.
Driving in Mud, Sand, Snow, or Ice
Use a low gear when driving in mud —the
deeper the mud, the lower the gear. Keep
the vehicle moving to avoid getting stuck.
See Manual Mode 0177.
Traction changes when driving on sand. On
loose sand, such as on beaches or sand
dunes, the tires tend to sink into the sand.
This affects steering, accelerating, and
braking. Drive at a reduced speed and avoid
sharp turns or abrupt maneuvers.
Traction is reduced on hard packed snow
and ice and it is easy to lose control. Reduce
vehicle speed when driving on hard packed
snow and ice.
{Warning
Driving on frozen lakes, ponds, or rivers
can be dangerous. Ice conditions vary
greatly and the vehicle could fall through
the ice; you and your passengers could
drown. Drive your vehicle on safe
surfaces only.
Water Fording
Your vehicle is capable of driving through or
across deeper water depending on vehicle
trim level as follows:
.AT4, Elevation, and Denali –Up to
66 cm (26 in)
.AT4X –Up to 71 cm (28 in)
Before entering any water, determine the
water depth. Enter the water slowly. As
water depth increases, reduce the vehicle
speed to prevent potential vehicle damage
or loss of control.
{Warning
Driving through rushing water can be
dangerous. Deep water can sweep your
vehicle downstream and you and your
passengers could drown. If it is only (Continued)

Warning (Continued)
shallow water, it can still wash away the
ground from under your tires. Traction
could be lost, and the vehicle could roll
over. Do not drive through rushing water.
Caution
Do not drive through standing water if it
is deep enough to cover the wheel hubs,
axles, or exhaust pipe. Deep water can
damage the axle and other vehicle parts.
If the standing water is not too deep, drive
through it slowly. At faster speeds, water
can get into the engine and cause it to stall.
Stalling can occur if the exhaust pipe is
under water.
Do not turn off the ignition when driving
through water. If the exhaust pipe is under
water, the engine will not start.
Always drive in the direction of waves.
Avoid oncoming vehicles as they will
increase the water depth hitting your
vehicle. Be aware of submerged obstacles as they
can damage your vehicle or cause loss of
control.
Never open the vehicle doors while in the
water.
When going through water, the brakes get
wet and it may take longer to stop. After
exiting the water, repeatedly and gently
apply the brakes to dry them off and
restore effectiveness. See
Driving on Wet
Roads 0159.
After Driving Your Vehicle Off-Road
Be sure to switch out of Off-Road Mode or
Terrain Mode on your Driver Mode Control
to return to normal driving. See Driver Mode
Control 0187.
Remove any brush or debris that has
collected on the underbody or chassis,
or under the hood. Clean the lens of the
underbody camera. These accumulations can
be a fire hazard.
After operation in mud or sand, have the
brake linings cleaned and checked. These
substances can cause glazing and uneven
braking. Check the body structure, driveline, steering,
suspension, wheels, tires, and exhaust
system for damage, and check the fuel lines
and cooling system for any leakage.
{Warning
Lifting a vehicle and getting under it to
do maintenance or repairs is dangerous
without the appropriate safety equipment
and training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could be
badly injured or killed if the vehicle slips
off the jack. If a jack is provided with the
vehicle, only use it for changing a
flat tire.
The extreme conditions of off-road driving
require more frequent maintenance service.
See "Severe Conditions Requiring More
Frequent Maintenance" and "Additional
Required Services —Severe Service" on
Maintenance Schedule 0328.

158 Driving and Operating
Off-Road App
Overview
The vehicle is equipped with an Off-Road
App to assist in monitoring the motion and
status of your vehicle, which can be
beneficial in off-road environments. See
Off-Road Driving0153.
The Off-Road App displays data such as the
vehicle’s compass bearing, altitude, axle
locker status, pitch/roll angle, and more,
depending on how your vehicle is equipped.
Some gauges track of the maximum values
you have achieved, and you can reset the
values to start over.
{Warning
Taking your eyes off the road for too
long or too often while using any
infotainment feature can cause a crash.
You or others could be injured or killed.
Do not give extended attention to
infotainment tasks while driving. Limit
your glances at the vehicle displays and
focus your attention on driving. Use voice
commands whenever possible.
Getting Started
To open the app, select the OFF ROAD icon
from the infotainment home screen. The
available off-road tools are displayed
horizontally across the screen. Scroll left or
right to view more tools. Additionally, the
tools are grouped by labels Baja, Terrain,
and Overlanding at the top of the screen.
These labels are shortcuts to the tools that
may be helpful in those respective driving
conditions, although all tools are actively
collecting data at all times. Baja and Terrain
are also selectable as a driving mode. See
Driver Mode Control 0187.
.Baja –High-speed driving on low traction
surfaces
.Terrain –For rough terrain at low speeds
.Overlanding –For exploring without using
roads
Certain tools save minimum and maximum
values for the data they are collecting,
which you can reset as needed. Touch the
Reset symbol
jon the screen to reset the
values. Depending on how the vehicle is equipped,
the off-road tools in the app may include:
Altimeter :
Displays current elevation.
Maintains lowest and highest values, which
can be reset as needed.
Axle locker status : Identifies each axle as
locked or unlocked. A tire will be highlighted
if slip due to low traction is detected. See
Locking Front Axle 0192 and
Locking Rear Axle 0191.
Camera app shortcut : Launches the Camera
App for exterior camera views. See Surround
Vision System 0209.
Compass : Displays direction of travel. If the
vehicle navigation system is actively routing
to a destination, an indicator on the
compass shows the bearing to the
destination. See Compass075.
G-Force : Displays longitudinal and lateral
acceleration and max G-force.
Pitch and roll : Shows real-time vehicle pitch
and roll in a 3D gauge.
Steering angle : Displays degrees of steering
rotation for the front wheels.

160 Driving and Operating
{Warning
Coasting downhill in N (Neutral) or with
the ignition off is dangerous. This can
cause overheating of the brakes and loss
of steering assist. Always have the engine
running and the vehicle in gear.
.Drive at speeds that keep the vehicle in
its own lane. Do not swing wide or cross
the center line.
.Be alert on top of hills; something could
be in your lane (e.g., stalled car, crash).
.Pay attention to special road signs
(e.g., falling rocks area, winding roads,
long grades, passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or IceCaution
To avoid damage to the wheels and
brake components, always clear snow and
ice from inside the wheels and
underneath the vehicle before driving. Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on Traction Control. See
Traction
Control/Electronic Stability Control 0185.
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0183.
.Allow greater following distance and
watch for slippery spots. Icy patches can
occur on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid sudden
steering maneuvers and braking while
on ice.
.Turn off cruise control.
Cold Weather Mode
In very low temperatures, a cold weather
message may display on the Driver
Information Center (DIC). The engine speed,
transmission shift patterns, and cabin fan
speed may operate differently to enable the
vehicle to warm up quicker. You can
manually override the cabin fan speed in
cold weather mode.
Blizzard Conditions
Stop the vehicle in a safe place and signal
for help. Stay with the vehicle unless there
is help nearby. If possible, use Roadside
Assistance. See Roadside Assistance Program
0 341. To get help and keep everyone in the
vehicle safe:
.Turn on the hazard warning flashers.
.Tie a red cloth to an outside mirror.
{Warning
Snow can trap engine exhaust under the
vehicle. This may cause exhaust gases to
get inside. Engine exhaust contains
carbon monoxide (CO), which cannot be
seen or smelled. It can cause
unconsciousness and even death.

Driving and Operating 161
Warning (Continued)
If the vehicle is stuck in snow:
.Clear snow from the base of the
vehicle, especially any blocking the
exhaust pipe.
.Open a window about 5 cm (2 in) on
the vehicle side that is away from the
wind, to bring in fresh air.
.Fully open the air outlets on or under
the instrument panel.
.Adjust the climate control system to
circulate the air inside the vehicle and
set the fan speed to the highest
setting. See“Climate Control Systems.”
For more information about CO, see
Engine Exhaust 0174.
To save fuel, run the engine for short
periods to warm the vehicle and then shut
the engine off and partially close the
window. Moving about to keep warm also
helps.
If it takes time for help to arrive, when
running the engine, push the accelerator
pedal slightly so the engine runs faster than
the idle speed. This keeps the battery charged to restart the vehicle and to signal
for help with the headlamps. Do this as
little as possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the wheels to
free the vehicle when stuck in sand, mud,
ice, or snow. See
“Rocking the Vehicle to Get
It Out” later in this section.
If equipped, the front and rear axles may be
locked to improve traction. See Locking Front
Axle 0192 and
Locking Rear Axle 0191.
The Traction Control System (TCS) can often
help to free a stuck vehicle. See Traction
Control/Electronic Stability Control 0185.
If TCS cannot free the vehicle, see “Rocking
the Vehicle to Get it Out” following.
{Warning
If the vehicle's tires spin at high speed,
they can explode, and you or others
could be injured. The vehicle can
overheat, causing an engine compartment
fire or other damage. Spin the wheels as
little as possible and avoid going above
56 km/h (35 mph). For information about using tire chains on
the vehicle, see
Tire Chains0302.
Rocking the Vehicle to Get It Out
Turn the steering wheel left and right to
clear the area around the front wheels. For
four-wheel-drive vehicles, shift into
Four-Wheel Drive High. Turn the TCS off.
Shift back and forth between R (Reverse) and
a forward gear, spinning the wheels as little
as possible. To prevent transmission wear,
wait until the wheels stop spinning before
shifting gears. Slowly spinning the wheels in
the forward and reverse directions causes a
rocking motion that could free the vehicle.
If that does not get the vehicle out after a
few tries, it might need to be towed out.
See Transporting a Disabled Vehicle 0314.
Recovery hooks can be used, if the vehicle
has them.
Recovery Hooks
{Warning
Never pull on recovery hooks from the
side. The hooks could break and you and
others could be injured. When using
recovery hooks, always pull the vehicle
from the front.

168 Driving and Operating
This vehicle has pushbutton starting.
The remote key must be in the vehicle for
the system to operate. If the pushbutton
start is not working, the vehicle may be
near a strong radio antenna signal causing
interference to the Keyless Access system.
SeeRemote Key Operation 07.
To shift out of P (Park), the ignition must be
on or in Service Mode and the brake pedal
must be applied.
Stopping the Engine/OFF (No Indicator
Lights) : When the vehicle is stopped, press
ENGINE START/STOP once to turn the
engine off.
If the vehicle is in P (Park), the ignition will
turn off, and Retained Accessory Power

If the vehicle is not in P (Park), the ignition
will return to accessory mode and display
the message SHIFT TO PARK in the Driver
Information Center (DIC). When the vehicle
is shifted into P (Park), the ignition will
turn off.
Do not turn the engine off when the vehicle
is moving. This will cause a loss of power
assist in the brake and steering systems and
disable the airbags. If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
After shifting to N (Neutral), firmly apply
the brakes and steer the vehicle to a
safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition off. The
shift lever must be in P (Park) to turn the
ignition off.
4. Set the parking brake. See Electric
Parking Brake 0183.
{Warning
Turning off the vehicle while moving may
cause loss of power assist in the brake
and steering systems and disable the
airbags. While driving, only shut the
vehicle off in an emergency. If the vehicle cannot be pulled over, and
must be shut off while driving, press and
hold ENGINE START/STOP for longer than
two seconds, or press twice in five seconds.
Accessory Mode (Amber Indicator Light) :
This mode allows some electrical accessories
to be used when the engine is off.
With the ignition off, pressing the button
one time without the brake pedal applied
will place the ignition system in
accessory mode.
The ignition will switch from accessory
mode to OFF after five minutes to prevent
battery rundown.
ON/RUN/START (Green Indicator Light) :
This
mode is for driving and starting. With the
ignition off, and the brake pedal applied,
pressing the button once will place the
ignition system in ON/RUN/START. Once
engine cranking begins, release the button.
Engine cranking will continue until the
engine starts. See Starting the Engine 0169.
The ignition will then remain in ON/RUN.

Drive Systems
Four-Wheel Drive
If equipped, four-wheel drive engages the
front axle for extra traction.
Read the appropriate section for transfer
case operation before using.
Caution
Do not drive on clean, dry pavement in
4
mand 4n(if equipped) for an extended
period of time. These conditions may
cause premature wear on the vehicle’s
powertrain.
Driving on clean, dry pavement in 4
mor
4
nmay:
.Cause a vibration to be felt in the
steering system.
.Cause tires to wear faster.
{Warning
If equipped with four-wheel drive, the
vehicle will be free to roll if the transfer
case is in N (Neutral), even when the shift
lever is in P (Park). You or someone else
could be seriously injured. Be sure the
transfer case is in a drive gear —2
m, 4m,
or 4
n— or set the parking brake before
placing the transfer case in N (Neutral).
See Shifting Into Park 0172.
Caution
Extended high-speed operation in 4n
may damage or shorten the life of the
drivetrain.
An engagement noise and bump is normal
when shifting between 4
nand 4mor
N (Neutral), with the engine running.
Shifting into 4
nwill turn Traction Control
and StabiliTrak/Electronic Stability Control
(ESC) off. See Traction Control/Electronic

Brakes
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.
If there is a problem with ABS, this warning
light stays on. SeeAntilock Brake System
(ABS) Warning Light 092. ABS does not change the time needed to
get a foot on the brake pedal and does not
always decrease stopping distance. If you
get too close to the vehicle ahead, there will
not be enough time to apply the brakes if
that vehicle suddenly slows or stops. Always
leave enough room ahead to stop, even
with ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down firmly. Hearing and feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and braking at the same
time. In many emergencies, steering can
help even more than braking.
Electric Parking Brake
The Electric Parking Brake (EPB) can always
be applied, even if the vehicle is off. In case
of insufficient electrical power, the EPB
cannot be applied or released. To prevent
draining the battery, avoid unnecessary
repeated cycles of the EPB.
The system has a red parking brake status
light and an amber service parking brake
warning light. See
Electric Parking Brake
Light 091 and
Service Electric Parking Brake Light 092.
There are also parking brake-related Driver
Information Center (DIC) messages.
