.After exiting the water, repeatedly and
gently apply the brakes to dry them off
and restore effectiveness.
If Something Goes Wrong
If during your off-road experience a warning
light or warning message displays on the
instrument cluster, or if the vehicle sustains
damage, stop driving as soon as it is safe to
do so. Correct the condition if possible
before continuing driving. If a warning light
or message appears, or if the condition
cannot be corrected, see your dealer. See
Vehicle Messages0135.
If the vehicle is operating with reduced
acceleration or reduced propulsion, stop
your off-road experience and drive slowly to
an accessible point for further assistance.
The vehicle should be taken to your dealer
for service as soon as possible. See
Propulsion Power Messages 0136 and
Propulsion Power is Limited Light 0115.
{Warning
A vehicle with driveline damage may roll
when shifted into P (Park). Always set
the Electric Parking Brake before
inspecting for driveline damage or when

securing the vehicle on a flatbed tow
truck. SeeElectric Parking Brake 0205
and
Transporting a Disabled Vehicle 0378.
After Driving Your Vehicle Off-Road
Be sure to switch out of Off-Road Mode or
Terrain Mode to return to normal driving.
See Driver Mode Control 0209.
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.
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 0389.
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 other vehicle
systems for damage, or have these
inspections done by your dealer.
{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.
Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop and
accelerate. Always drive slower in these
types of driving conditions and avoid driving
through large puddles and deep-standing or
flowing water.

16702912) - 2024 - CRC - 1/17/23
Driving and Operating 191
Driving on steep hills or through mountains
is different than driving on flat or rolling
terrain. Be sure to:
.Use regenerative braking to help slow the
vehicle or maintain speed by keeping the
vehicle in gear and limiting the initial
battery charge to 80% or less. See
Regenerative Braking0206.
.When braking is necessary, use frequent,
light taps of the brake pedal. This
maximizes regenerative braking and
minimizes the load on the vehicle brake
system.
.Keep the vehicle serviced and in good
shape.
.Check all fluid levels, brakes, tires, and
cooling system.
.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 Ice
Caution
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:
.Turn off cruise control.
.If enabled, turn off One-Pedal Driving. See
One-Pedal Driving 0203.
.If turned off, turn on the Traction Control
System (TCS) and Electronic Stability
Control (ESC). See Traction Control/
Electronic Stability Control 0207.
.Select the Snow/Ice driver mode. See
Driver Mode Control 0209.
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.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.
.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) 0204.
.Avoid using the Regen on Demand
paddle. See Regenerative Braking 0206.
Blizzard Conditions
If you become stranded or cannot continue
driving due to winter storm conditions, stop
the vehicle in a safe place and signal for
help. If possible, use Roadside Assistance
Program 0399. Stay with the vehicle unless
there is help nearby.

hill, the Electric Parking Brake (EPB) may
apply automatically. The driver may not be
able to release the EPB using the EPB
switch. It should automatically release when
the vehicle is shifted out of P (Park).
Leaving the Vehicle with the Propulsion
System On
{Warning
It is dangerous to get out of the vehicle
if the vehicle is not in P (Park) with the
parking brake set. The vehicle can roll. (Continued)
Warning (Continued)
Do not leave the vehicle when the

16702912) - 2024 - CRC - 1/17/23
200 Driving and Operating
Parking the vehicle in extreme cold for
several days without the charge cord
connected may cause the vehicle not to
start. Plug the vehicle in to allow the high
voltage battery to be warmed sufficiently.
To shift out of P (Park):1. Apply the brake pedal.
2. Verify that the vehicle is unplugged and the vehicle ready light is on.
3. Move the shift lever to the desired position.
After releasing the shift lever, it will return
to the center position.
The P indicator will turn white and the gear
indicator on the shift lever will turn red
when the vehicle is no longer in P (Park).
If the vehicle cannot shift from P (Park), a
Driver Information Center (DIC) message
may be displayed. Check that the vehicle is
on, the vehicle ready light is on, and the
brake pedal is applied when you are
attempting to shift out of P (Park). If all of
these are met but the vehicle will not shift
out of P (Park), see your dealer for service.
If equipped, the Buckle to Drive feature may
prevent shifting from P (Park). See Buckle To
Drive 053.Electric Drive Unit
The vehicle uses an electric drive unit. The
shift pattern is displayed on the front of the

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 be
applied when the vehicle is on or off.
If there is not enough 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 EPB status light and
an amber service EPB warning light. See
Electric Parking Brake Light
0116 and
Service Electric Parking Brake Light 0116.
There are also parking brake-related Driver
Information Center (DIC) messages.
Before leaving the vehicle, check the red EPB
status light to ensure that the EPB is
applied.
If a message displays on the DIC indicating
the electric drive unit is unable to shift, the
service EPB light is on, and the EPB light
flashes at the same time, the system must
be reset. Start the vehicle, apply the EPB,
and then release it. The message and light
should turn off. See Electric Parking Brake
Light 0116 and
Service Electric Parking Brake Light 0116.EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch.
The red EPB status light will flash and then
stay on once the EPB is fully applied. If the
red EPB status light flashes continuously,
then the EPB is only partially applied or
there is a problem with the EPB. A DIC message will display. Release the EPB and
try to apply it again. If the light does not
come on, or keeps flashing, have the vehicle
serviced. Do not drive the vehicle if the red
EPB light is flashing. See your dealer.
If the amber service EPB warning light is on,
press the EPB switch. Continue to hold the
switch until the red EPB status light remains
on. If the amber service EPB warning light is
on, see your dealer.
If the EPB is applied while the vehicle is
moving, the vehicle will decelerate as long
as the switch is pressed. If the switch is
pressed until the vehicle comes to a stop,
the EPB will remain applied.
The vehicle may automatically apply the EPB
in some situations when the vehicle is not
moving. This is normal, and is done to
periodically check the correct operation of
the EPB system, or as required by other
safety functions that utilize the EPB.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB:
1. Turn the vehicle on.
2. Apply and hold the brake pedal.

16702912) - 2024 - CRC - 1/17/23
206 Driving and Operating
3. Press the EPB switch.
The EPB is released when the red parking
brake status light is off.
If the amber service EPB warning light is on,
release the EPB by pressing and holding the
EPB switch. Continue to hold the switch
until the red parking brake status light is
off. If either light stays on after release is
attempted, see your dealer.
Caution
Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake
system parts. Make sure that the parking
brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and parking on a
hill, see Driving Characteristics and Towing
Tips 0294.
Automatic EPB Release
The EPB automatically releases if the vehicle
is running, placed into gear, and an attempt
is made to drive away. Avoid rapid
acceleration when the EPB is applied, to
preserve parking brake lining life.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional braking to
activate the Antilock Brake System (ABS) if
the brake pedal is not pushed hard enough
to activate ABS normally. Minor noise, brake
pedal pulsation, and/or pedal movement
during this time may occur. Continue to
apply the brake pedal as the driving
situation dictates. Brake Assist disengages
when the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when
driving may result in injury, death,
or vehicle damage. See Defensive Driving
0 183.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) prevents the vehicle from
rolling in an unintended direction during the
transition from brake pedal release to accelerator pedal apply. The brakes release
when the accelerator pedal is applied. If the
accelerator pedal is not applied within a few
minutes, the Electric Parking Brake will
apply. The brakes may also release under
other conditions. Do not rely on HSA to hold
the vehicle.
HSA is available when the vehicle is facing
uphill in a forward gear, or when facing
downhill in R (Reverse). The vehicle must
come to a complete stop on a grade for HSA
to activate.
Regenerative Braking
Regenerative braking takes some of the
energy from the moving vehicle and turns it
back into electrical energy. This energy is
then stored back into the high voltage
battery system, contributing to increased
energy efficiency.
Regenerative power may be limited when
the battery is near full charge or cold. See
“Regenerative Power Limited”
underPower
Indicator Gauge 0111. Regenerative braking
supplements your vehicle’s conventional
brakes, especially when going downhill. See
Hill and Mountain Roads 0190.

Ride Height Descriptions
Entry/Exit
Entry/Exit height is the lowest height
option. This ride height lowers the vehicle
for easy entry and exit, and loading and
unloading of cargo.
This ride height can be selected in the Ride
Height Menu at any vehicle speed; but will
not lower until the vehicle slows.
The vehicle automatically raises to Normal
height from Entry/Exit height when the
vehicle speed increases.
The driver can enable Easy Exit Vehicle
Height Mode to automatically lower to
Entry/Exit Height when the vehicle is shifted to P (Park). Easy Exit Vehicle Height Mode
may be enabled via the infotainment screen
under Settings > Vehicle > Ride Height.
When the vehicle is higher than Normal
height, Easy Exit Vehicle Height Mode is
disabled. When the vehicle is in Tow/Haul
Mode, Off-Road Mode, Terrain Mode, or it
senses a trailer is connected, Easy Exit
Vehicle Height Mode is disabled.
Aerodynamic
Aerodynamic height is lower than Normal
height. The vehicle automatically lowers the
vehicle at higher vehicle speeds to improve
aerodynamics. This is not a selectable option
on the Ride Height menu.
The vehicle will raise to Normal height when
the vehicle slows.
Aerodynamic height is automatically
disabled when a trailer is connected to the
vehicle, Tow/Haul mode is active, or the
vehicle is at Increased Height.
Normal
Normal height is the standard vehicle height
used for everyday driving.
Increased
Increased height is higher than Normal
height. This ride height raises the vehicle for
off-road use. Increased height can be
selected in the Ride Height Menu while
vehicle speed is slower than average speeds.
Maximum
Maximum height is higher than Increased
height. This ride height raises the vehicle for
off-road use and maximum ground
clearance. Maximum height can be selected
in the Ride Height Menu while vehicle speed
is slower. When the vehicle speeds up, the
vehicle will lower to Increased height.
Suspension Modes
The air suspension has two special modes,
Service Mode and Alignment Mode, located
in the infotainment screen under Settings >
Vehicle > Suspension.
Service Mode
Service Mode will disable all air suspension
operation including raising and lowering the
vehicle and operation of the air compressor.
This mode is useful when the vehicle is
being towed on a flat bed or when any
work under the vehicle is being performed.

Driving and Operating 213
Service Mode is recommended when the
vehicle is put on a hoist or a floor jack is
used to raise a corner. Service Mode
automatically disables when the vehicle
speeds up.
Alignment Mode
Alignment Mode will optimize the vehicle
height to provide the most accurate wheel
alignment. This mode should be enabled
once the vehicle is driven onto the
alignment station.
To enable Alignment Mode, ensure the
vehicle is at Normal Height and shift the
vehicle to N (Neutral). Alignment Mode
automatically disables when the vehicle
speeds up.
Air Suspension Operation with Door(s) or
Hood Open
The air suspension will temporarily suspend
all height changes while the hood or any
door is open.
System Over-Temperature
If the air suspension is under heavy use, the
system may temporarily suspend all height
changes to allow the compressor to cool
down. When this occurs and a heightchange is requested, the message LEVELING
SYSTEM UNAVAILABLE will display in the
instrument cluster.
Air Suspension Service
If a SERVICE LEVELING SYSTEM message
displays in the instrument cluster, see your
authorized dealer immediately.
Cruise Control
If equipped, cruise control allows the vehicle
to maintain a set speed of 40 km/h
(25 mph) or more without active
acceleration. Cruise control does not work at
speeds below 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.
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.
Cruise control will disengage if:
.The Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system begins to limit wheel spin.
See
Traction Control/Electronic Stability
Control 0207.
.TCS or StabiliTrak/ESC is turned off.
.A collision alert occurs. See Forward
