14430421) - 2021 - CRC - 2/10/20
178 Driving and Operating
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. SeeTraction
Control/Electronic Stability Control 0202.
.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) 0201.
.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.
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
0 331. 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.
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 0190. 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 0207 and
Locking Rear Axle 0206.
The Traction Control System (TCS) can often
help to free a stuck vehicle. See Traction
Control/Electronic Stability Control 0202.
If TCS cannot free the vehicle, see “Rocking
the Vehicle to Get it Out” following.

194 Driving and Operating
To use this feature:1. Move the shift lever to L (Manual Mode).
2. Press the plus/minus button on the shift lever to select the desired range of gears
for current driving conditions.
When the shift lever is moved from
D (Drive) to L (Manual Mode), a number
displays next to the L, indicating the current
transmission range.
This number is the highest gear that the
transmission will command while operating
in L (Manual Mode). All gears below that
number are available. As driving conditions
change, the transmission can automatically
shift to lower gears. For example, when L5 is
selected, 1 (First) through 5 (Fifth) gears are
automatically shifted by the transmission,
but 6 (Sixth) cannot be used until the plus/
minus button on the shift lever is used to
change to the range.
When the shift lever is moved from
D (Drive) to L (Manual Mode), a downshift
may occur. The gear that the transmission is
operating in when the shift lever is moved
from D (Drive) to L (Manual Mode)
determines if a downshift occurs. See the
following chart. 6-Speed Automatic Transmission

202 Driving and Operating
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. SeeDefensive Driving
0 170.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) temporarily 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 or automatically release after a few
seconds. 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.
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control System
(TCS) and StabiliTrak/Electronic Stability
Control (ESC), an electronic stability control
system. These systems help limit wheel spin
and assist the driver in maintaining control,
especially on slippery road conditions.
TCS activates if it senses that any of the
drive wheels are spinning or beginning to
lose traction. When this happens, TCS
applies the brakes to the spinning wheels
and reduces engine power to limit
wheel spin.
StabiliTrak/ESC activates when the vehicle
senses a difference between the intended
path and the direction the vehicle is actually
traveling. StabiliTrak/ESC selectively applies
braking pressure to any one of the vehicle
wheel brakes to assist the driver in keeping
the vehicle on the intended path.
If cruise control is being used and TCS or
StabiliTrak/ESC begins to limit wheel spin,
cruise control will disengage. Cruise control
may be turned back on when road
conditions allow.
Both systems come on automatically when
the vehicle is started and begins to move.
The systems may be heard or felt while
they are operating or while performing
diagnostic checks. This is normal and does
not mean there is a problem with the
vehicle.
It is recommended to leave both systems on
for normal driving conditions, but it may be
necessary to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. See
If the
Vehicle Is Stuck 0178 and “Turning the
Systems Off and On” later in this section.

14430421) - 2021 - CRC - 2/10/20
Driving and Operating 205
The HDC light displays on the instrument
cluster when enabled.
HDC can maintain vehicle speeds between
4 and 30 km/h (3 and 19 mph) on an incline
greater than or equal to a 10% grade.
A blinking HDC light indicates that the
system is actively applying the brakes to
maintain vehicle speed.
When HDC is set, that is the initial set
speed. It can be increased or decreased by
applying the accelerator or brake pedal.
Smaller HDC speed control adjustments are
accomplished using the cruise up or down
buttons. Each tap of the +RES will increase
the set speed by 0.8 km/h (0.5 mph), while
each tap of the SET–will decrease the set
speed by 0.8 km/h (0.5 mph). This adjusted
speed becomes the new set speed. HDC will remain enabled between 30 and
60 km/h (19 and 37 mph), however vehicle
speed cannot be set or maintained in this
range. It will automatically disable if the
vehicle speed is above 80 km/h (50 mph) or
above 60 km/h (37 mph) for at least
30 seconds.5must be pressed again to
re-enable HDC.
When enabled, if the vehicle is at a speed
above 30 km/h (19 mph) and less than
60 km/h (37 mph), a DIC message will
display instructing the driver to reduce
speed for HDC operation.
Cruise control will not function while HDC is
enabled and vehicle speed is below 40 km/h
(25 mph).
Driver Mode Control
Driver Mode Control (DMC) allows the driver
to adjust the overall driving character to
better suit preference or specific driving
scenarios by adjusting multiple sub-system
calibrations simultaneously. Mode
availability is dependent upon vehicle trim
level, region, and optional features.
Transfer Case Knob with Off-Road Mode
Off-Road Mode
Use this mode for off-road recreational
driving at moderate speeds, on grass, gravel,
dirt, unpaved roads, or snow-covered roads.
The accelerator pedal will be more sensitive
to provide finer control of the torque at the
wheels. StabiliTrak/Electroinic Stability
Control (ESC), the Antilock Brake System
(ABS), and the Traction Control System(TCS)
will change for optimal off-road
performance.
For more information on off-road driving.

208 Driving and Operating
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.
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 0202.
If a collision alert occurs when cruise control
is activated, cruise control is disengaged. See
Forward Collision Alert (FCA) System 0213.
When road conditions allow you to safely
use it again, cruise control can be turned
back on.
If equipped with Hill Descent Control (HDC),
the cruise control will disengage if HDC is
active.
If the brakes are applied, the cruise control
disengages.
5: Press to turn the system on or off.
A white indicator comes on in the
instrument cluster when cruise control is
turned on.

The cruise control indicator on the
instrument cluster turns green after cruise
control has been set to the desired speed.
SeeInstrument Cluster 080.
Resuming a Set Speed
If the cruise control is set at a desired speed
and then the brakes are applied or
*is
pressed, the cruise control is disengaged
without erasing the set speed from memory.
Once the vehicle speed reaches about
40 km/h (25 mph) or more, press +RES
briefly. The vehicle returns to the previous
set speed.
Increasing Speed While Using Cruise Control
If the cruise control system is already
activated:
.Press and hold +RES until the desired
speed is reached, then release it.
.To increase vehicle speed in small
increments, briefly press +RES. For each
press, the vehicle goes about 1 km/h
(1 mph) faster.
The speedometer reading can be displayed
in either English or metric units. See Driver
Information Center (DIC) (Base Level) 093 or Driver Information Center (DIC) (Uplevel)

the units displayed.
Reducing Speed While Using Cruise Control
If the cruise control system is already
activated:
.Press and hold SET– until the desired
lower speed is reached, then release it.
.To slow down in small increments, briefly
press SET– . For each press, the vehicle
goes about 1 km/h (1 mph) slower.
The speedometer reading can be displayed
in either English or metric units. See Driver
Information Center (DIC) (Base Level) 093 or
Driver Information Center (DIC) (Uplevel)
0 95. The increment value used depends on
the units displayed.
Passing Another Vehicle While Using Cruise
Control
Use the accelerator pedal to increase the
vehicle speed. When you take your foot off
the pedal, the vehicle will slow down to the
previous set cruise speed. While pressing the
accelerator pedal or shortly following the
release to override cruise control, briefly
pressing SET– will result in cruise control set
to the current vehicle speed. Using Cruise Control on Hills
How well the cruise control will work on
hills depends on the vehicle speed, load, and
the steepness of the hills. When going up
steep hills, you might have to step on the
accelerator pedal to maintain your speed.
When going downhill, you might have to
brake or shift to a lower gear to keep your
speed down. If the brake pedal is applied,
cruise control will disengage.
Ending Cruise Control
There are three ways to end cruise control:
.Step lightly on the brake pedal.
.Press*.
.To turn off cruise control, press5.
Erasing Speed Memory
The cruise control set speed is erased from
memory if
5is pressed or if the ignition is
turned off.
Driver Assistance Systems
This vehicle may have features that work
together to help avoid crashes or reduce
crash damage while driving, backing, and
parking. Read this entire section before
using these systems.

214 Driving and Operating
Collision Alert
When your vehicle approaches another
detected vehicle too rapidly, the red lights
will flash on the windshield. Also, eight
rapid high-pitched beeps will sound from the
front. When this Collision Alert occurs, the
brake system may prepare for driver braking
to occur more rapidly which can cause a
brief, mild deceleration. Continue to apply
the brake pedal as needed. Cruise control
may be disengaged when the Collision Alert
occurs.
Tailgating Alert
The vehicle ahead indicator will display
amber when you are following a detected
vehicle ahead much too closely.
Selecting the Alert Timing
The Collision Alert control is on the steering
wheel. Press
[to set the FCA timing to
Far, Medium, Near, or Off. The first button
press shows the current setting on the DIC.
Additional button presses will change this
setting. The chosen setting will remain until
it is changed and will affect the timing of
both the Collision Alert and the Tailgating
Alert features. The timing of both alerts will
vary based on vehicle speed. The faster the
vehicle speed, the farther away the alert will
occur. Consider traffic and weather
conditions when selecting the alert timing.
The range of selectable alert timing may not
be appropriate for all drivers and driving
conditions.
Unnecessary Alerts
FCA may provide unnecessary alerts for
turning vehicles, vehicles in other lanes,
objects that are not vehicles, or shadows.
These alerts are normal operation and the
vehicle does not need service.
Cleaning the System
If the FCA system does not seem to operate
properly, this may correct the issue:
.Clean the outside of the windshield in
front of the rearview mirror.
.Clean the entire front of the vehicle.
.Clean the headlamps.
Automatic Emergency
Braking (AEB)
If the vehicle has Forward Collision Alert
(FCA), it also has AEB, which includes
Intelligent Brake Assist (IBA). When the
system detects a vehicle ahead in your path
that is traveling in the same direction that
you may be about to crash into, it can
provide a boost to braking or automatically
brake the vehicle. This can help avoid or
lessen the severity of crashes when driving
in a forward gear. Depending on the
situation, the vehicle may automatically
brake moderately or hard. This automatic
emergency braking can only occur if a
vehicle is detected. This is shown by the FCA
vehicle ahead indicator being lit. See
Forward Collision Alert (FCA) System 0213.
The system works when driving in a forward
gear between 8 km/h (5 mph) and 80 km/h
(50 mph).

Warning (Continued)
trailer only if all the steps in this section
have been followed. Ask your dealer for
advice and information about towing a
trailer with the vehicle.
Driving with a Trailer
Trailering is different than just driving the
vehicle by itself. Trailering means changes in
handling, acceleration, braking, durability,
and fuel economy. Successful, safe trailering
takes correct equipment, and it has to be
used properly.
The following information has many
time-tested, important trailering tips and
safety rules. Many of these are important
for your safety and that of your passengers.
Read this section carefully before pulling a
trailer.
When towing a trailer:
.Become familiar with and follow all state
and local laws that apply to trailer
towing. These requirements vary from
state to state.
.State laws may require the use of
extended side view mirrors. Even if not
required, you should install extended side
view mirrors if your visibility is limited or
restricted while towing.
.Do not tow a trailer during the first
800 km (500 mi) of vehicle use to prevent
damage to the engine, axle, or other
parts.
.It is recommended to perform the first oil
change before heavy towing.
.During the first 800 km (500 mi) of trailer
towing, do not drive over 80 km/h
(50 mph) and do not make starts at full
throttle.
.Vehicles can tow in D (Drive). Tow/Haul
Mode is recommended for heavier trailers.
SeeTow/Haul Mode 0195. If the
transmission downshifts too often, a
lower gear may be selected using Manual
Mode. See Manual Mode 0193.
If equipped, the following driver assistance
features should be turned off when towing
a trailer:
.Adaptive Cruise Control (ACC)
.Super Cruise Control
.Lane Keep Assist (LKA)
.Park Assist
.Reverse Automatic Braking (RAB)
If equipped, the following driver assistance
features should be turned to alert or off
when towing a trailer:
.Automatic Emergency Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian Braking (FPB)
If equipped with Lane Change Alert (LCA),
the LCA detection zones that extend back
from the side of the vehicle do not move
further back when a trailer is towed. Use
caution while changing lanes when towing a
trailer.
If equipped with Rear Cross Traffic Alert
(RCTA), use caution while backing up when
towing a trailer, as the RCTA detection zones
that extend out from the back of the vehicle
do not move further back when a trailer is
towed.
{Warning
To prevent serious injury or death from
carbon monoxide (CO), when towing a
trailer:
.Do not drive with the liftgate, trunk/
hatch, or rear-most window open. (Continued)
