124STARTING AND OPERATING
Towing Requirements — Tires
Do not attempt to tow a trailer while using a compact
spare tire.
 Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.
 Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle.
 Check the trailer tires for proper tire inflation pressures
before trailer usage.
 Check for signs of tire wear or visible tire damage
before towing a trailer.
 Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits.
 For further information
Úpage 246.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
 An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required. 
Trailer brakes are recommended for trailers over
1,000 lb (453 kg) and required for trailers in excess of
1,543 lb (700 kg).
Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-pin
wiring harness. Use a factory-approved trailer harness and
connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.
NOTE:
Disconnect the trailer wiring connector from the vehicle
(or any other device plugged into vehicle’s electrical
connectors) before launching a boat into water.
 Be sure to reconnect once clear from water area.
WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an
accident.
 Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and the
vehicle in front of you. Failure to do so could result
in an accident.
CAUTION!
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.

TOWING TIPS
Before towing, practice turning, stopping, and backing up
the trailer in an area located away from heavy traffic.
Automatic Transmission
Select the DRIVE (D) range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. For increased engine braking on steep
downhill grades, select the LOW range.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
 When using the Cruise Control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
 Use Cruise Control in flat terrain and with light loads to
maximize fuel efficiency.

STARTING AND OPERATING127
RECREATIONAL TOWING
Recreational towing (with all four wheels on the ground, or
using a towing dolly) is NOT ALLOWED. This vehicle may be
towed on flatbed or vehicle trailer provided all four wheels
are OFF the ground.
DRIVING TIPS
DRIVING ON SLIPPERY SURFACES
Information in this section will aid in safe controlled
launches in adverse conditions.
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the front (driving)
wheels.
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should be
observed:
Slow down during rainstorms or when the roads are
slushy.
 Slow down if the road has standing water or puddles.
 Replace the tires when tread wear indicators first
become visible.
 Keep tires properly inflated.
 Maintain sufficient distance between your vehicle and
the vehicle in front of you to avoid a collision in a
sudden stop.
CAUTION!
Towing this vehicle with ANY of its wheels on the ground
can cause severe transmission and/or power transfer
unit damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the front
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice, snow,
wet, mud, loose sand, etc.).

SAFETY
SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The ABS provides increased vehicle stability and brake
performance under most braking conditions. The system
automatically prevents wheel lock and enhances vehicle
control during braking.
The ABS performs a self-check cycle to ensure that the
ABS is working properly each time the vehicle is started
and driven. During this self-check, you may hear a slight
clicking sound as well as some related motor noises.
The ABS is activated during braking when the system
detects one or more wheels are beginning to lock. Road
conditions such as ice, snow, gravel, bumps, railroad
tracks, loose debris, or panic stops may increase the
likelihood of ABS activation(s).
You also may experience the following normal
characteristics when the ABS activates:
ABS motor noise or clicking sounds (you may continue
to hear for a short time after the stop)
 Brake pedal pulsations
 A slight drop of the brake pedal at the end of the stop The ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification may
result in degraded ABS performance.
Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when the ignition
is placed in the ON/RUN mode and may stay on for as long
as four seconds.
If the ABS Warning Light remains on or comes on while
driving, it indicates that the anti-lock portion of the brake
system is not functioning and that service is required.
However, the conventional brake system will continue to
operate normally if the ABS Warning Light is on.
If the ABS Warning Light is on, the brake system should be
serviced as soon as possible to restore the benefits of
Anti-Lock Brakes. If the ABS Warning Light does not come
on when the ignition is placed in the ON/RUN mode, have
the light repaired as soon as possible.
WARNING!

The ABS contains sophisticated electronic equip -
ment that may be susceptible to interference caused
by improperly installed or high output radio transmit -
ting equipment. This interference can cause possible
loss of anti-lock braking capability. Installation of
such equipment should be performed by qualified
professionals.
 Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
 The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or the
traction afforded.
The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
 The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner that could jeopardize the user’s safety or the
safety of others.
WARNING!

SAFETY155
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced Electronic
Brake Control (EBC) system. This system includes
Anti-Lock Brake System (ABS), Brake Assist System (BAS),
Electronic Brake Force Distribution (EBD), Electronic Roll
Mitigation (ERM), Electronic Stability Control (ESC), Hill
Start Assist (HSA), and Traction Control System (TCS).
These systems work together to enhance both vehicle
stability and control in various driving conditions.
Your vehicle may also be equipped with Dynamic Steering
Torque (DST), Hill Descent Control (HDC), Rain Brake
Support (RBS), Ready Alert Braking (RAB), and Trailer
Sway Control (TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sensing
the rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit
of the system, you must apply continuous braking
pressure during the stopping sequence (do not “pump”
the brakes). Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Brake System Warning Light
The red Brake System Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may stay on for
as long as four seconds.
If the Brake System Warning Light remains on or comes on
while driving, it indicates that the brake system is not
functioning properly and that immediate service is
required. If the Brake System Warning Light does not
come on when the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
Dynamic Steering Torque (DST)
DST is a feature of the Electronic Stability Control (ESC)
and Electric Power Steering (EPS) modules that provides
torque at the steering wheel for certain driving conditions
in which the ESC module is detecting vehicle instability.
The torque that the steering wheel receives is only meant
to help the driver realize optimal steering behavior in order to reach/maintain vehicle stability. The only notification
the driver receives that the feature is active is the torque
applied to the steering wheel.
NOTE:The DST feature is only meant to help the driver realize the
correct course of action through small torques on the
steering wheel, which means the effectiveness of the DST
feature is highly dependent on the driver’s sensitivity and
overall reaction to the applied torque. It is very important
to realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering the
vehicle.
Electronic Brake Force Distribution (EBD)
EBD manages the distribution of the braking torque
between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent overslip
of the rear wheels to avoid vehicle instability, and to
prevent the rear axle from entering ABS before the
front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by monitoring
the driver’s steering wheel input and the speed of the
vehicle. When ERM determines that the rate of change of
the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during severe or
evasive driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. The
capabilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner, which
could jeopardize the user's safety or the safety of
others.

Full Off
To enter the “Full Off” mode, push the Sport Mode button
and then hold the ESC OFF button for two seconds while
the vehicle is stopped with the engine running. After two
seconds, a chime will sound, the ESC OFF Indicator Light
will illuminate, and the “ESC OFF” message will display in
the instrument cluster. To turn ESC on again, momentarily
push the ESC OFF button.ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator Light
in the instrument cluster will come on when the
ignition is placed in the ON mode. It should go
out with the engine running. If the ESC
Activation/Malfunction Indicator Light comes on
continuously with the engine running, a malfunction has
been detected in the ESC system. If this light remains on
after several ignition cycles, and the vehicle has been
driven several miles (km) at speeds greater than 30 mph
(48 km/h), see an authorized dealer as soon as possible
to have the problem diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light starts to
flash as soon as the tires lose traction and the ESC system
becomes active. The ESC Activation/Malfunction Indicator
Light also flashes when Traction Control System (TCS) is
active. If the ESC Activation/Malfunction Indicator Light
begins to flash during acceleration, ease up on the
accelerator and apply as little throttle as possible. Be sure
to adapt your speed and driving to the prevailing road
conditions.
The ESC OFF Indicator Light indicates the
customer has elected to have the Electronic
Stability Control (ESC) in a reduced mode.
NOTE:
The ESC Activation/Malfunction Indicator Light and the
ESC OFF Indicator Light come on momentarily each
time the ignition is placed in the ON/RUN position.
 Each time the ignition is placed in the ON/RUN posi -
tion, the ESC system will be on even if it was turned off
previously.
 The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
Emergency Stop Signal (ESS) —
If Equipped
The ESS activates the hazard lights at a faster than normal
speed when heavy brake pressure is applied. ESS will only
activate when the speed is above 31 mph (50 km/h). The
ESS operates independently of other lamps, and will turn
on and off automatically. This indicates to others that the
vehicle is stopping quickly.
NOTE:
A warning light will illuminate within the instrument
cluster to inform the driver that the ESS feature has
been activated.
 When towing a trailer, ESS will also activate the rear
indicator lights of the trailer.
WARNING!
In the ESC “Full Off” mode, the engine torque reduc -
tion and stability features are disabled. Therefore,
enhanced vehicle stability offered by the ESC system
is unavailable. In an emergency evasive maneuver,
the ESC system will not engage to assist in main -
taining stability. ESC “Full Off” mode is intended for
off-highway or off-road use only.
 With the ESC switched off, the enhanced vehicle
stability offered by ESC is unavailable. In an
emergency evasive maneuver, the ESC system
will not engage to assist in maintaining stability.
ESC “Full Off” mode is only intended for off-highway
or off-road use.
 The Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent all
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent collisions.

158SAFETY
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a complete stop
while on an incline. If the driver releases the brake while
stopped on an incline, HSA will continue to hold the brake
pressure for a short period. If the driver does not apply the
throttle before this time expires, the system will release
brake pressure and the vehicle will roll down the hill as
normal.
The following conditions must be met in order for HSA to
activate:
The feature must be enabled.
 The vehicle must be stopped.
 The parking brake must be off.
 The driver’s door must be closed.
 The vehicle must be on a sufficient grade.
 The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE gear).
 HSA will work in REVERSE gear and all forward gears.
The system will not activate if the transmission is in
PARK or NEUTRAL.
Rain Brake Support (RBS)
RBS may improve braking performance in wet conditions.
It will periodically apply a small amount of brake pressure
to remove any water buildup on the front brake rotors.
It functions when the windshield wipers are in LO or
HI speed. When Rain Brake Support is active, there is
no notification to the driver and no driver interaction
is required.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full braking
during emergency braking situations. It anticipates when
an emergency braking situation may occur by monitoring
how fast the throttle is released by the driver. The
Electronic Brake Controller (EBC) system will prepare
the brake system for a panic stop.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin for each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce
vehicle power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD) functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will
allow more vehicle torque to be applied to the wheel that
is not spinning. BLD may remain enabled even if TCS and
ESC are in reduced modes.
WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur, such
as on minor hills or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for active driving
involvement. It is always the driver’s responsibility to be
attentive to distance to other vehicles, people, and
objects, and most importantly brake operation to
ensure safe operation of the vehicle under all road
conditions. Your complete attention is always required
while driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a collision
or serious personal injury.

23_GG_OM_EN_USC_t.book Page 158

SAFETY163
If a Forward Collision Warning with Mitigation event begins
at a speed below 39 mph (62 km/h), the system may
provide the maximum braking possible to mitigate the
potential forward collision. If the Forward Collision
Warning with Mitigation event stops the vehicle
completely, the system will hold the vehicle at standstill for
two seconds and then release the brakes.

FCW Message

When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message
will be deactivated
Úpage 275.
NOTE:
 The minimum speed for FCW activation is 3mph
(5 km/h).
 The FCW alerts may be triggered on objects other than
vehicles such as guardrails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality. 
It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within a key cycle, the Active Braking portion of FCW will
be deactivated until the next key cycle.
 The FCW system is intended for on-road use only. If the
vehicle is taken off-road, the FCW system should be
deactivated to prevent unnecessary warnings to the
surroundings.
 The FCW system can become temporarily inoperative
due to heavy rain, sun rays, snow, ice, mud, or other
road contaminations accumulate on the front fascia/
bumper where the camera is located. If blockage is
detected, a “FCW Unavailability Due To Camera Blind -
ness” message will display in the cluster and FCW will
not function as intended. If a second occurance
happens within the same key cycle, a FCW telltail light
will illuminate only. This is normal operation. The
system will automatically recover and resume function
when the condition clears.
FCW Settings
The Forward Collision menu setting is located in the
Uconnect Settings Úpage 130.
NOTE:The default status of FCW is “Full On,” this allows the
system to provide warning and autonomous braking in the
event of a potential frontal collision.
Changing the FCW status to “Only Warning” prevents the
system from providing autonomous braking, or additional
brake support if the driver is not braking adequately in the
event of a potential frontal collision.
Changing the FCW status to “Off” deactivates the system,
so no warning or autonomous braking will be available in
case of a possible collision.
NOTE:The FCW system state is kept in memory from one ignition
cycle to the next. If the system is turned off, it will remain
off when the vehicle is restarted.
Changing FCW Sensitivity And Operating
Status
The FCW Sensitivity and Active Braking status are
programmable through the Uconnect system
Úpage 130.
The default sensitivity of FCW is the “Medium” setting and
the system status is “Warning & Braking”. This allows the
system to warn the driver of a possible collision with the
vehicle in front using audible/visual warnings and it
applies autonomous braking.
WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect every
type of potential collision. The driver has the
responsibility to avoid a collision by controlling the
vehicle via braking and steering. Failure to follow this
warning could lead to serious injury or death.

If A Deployment Occurs
The front air bags are designed to deflate immediately
after deployment.
NOTE:Front and/or side air bags will not deploy in all collisions.
This does not mean something is wrong with the air bag
system.
If you do have a collision which deploys the air bags, any
or all of the following may occur:
The air bag material may sometimes cause abrasions
and/or skin reddening to the occupants as the air bags
deploy and unfold. The abrasions are similar to friction
rope burns or those you might get sliding along a carpet
or gymnasium floor. They are not caused by contact
with chemicals. They are not permanent and normally
heal quickly. However, if you haven’t healed signifi -
cantly within a few days, or if you have any blistering,
see your doctor immediately.
 As the air bags deflate, you may see some smoke-like
particles. The particles are a normal by-product of the
process that generates the non-toxic gas used for air
bag inflation. These airborne particles may irritate the
skin, eyes, nose, or throat. If you have skin or eye irrita -
tion, rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation continues,
see your doctor. If these particles settle on your
clothing, follow the garment manufacturer’s instruc -
tions for cleaning.
Do not drive your vehicle after the air bags have deployed.
If you are involved in another collision, the air bags will not
be in place to protect you.
NOTE:
 Air bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
 After any collision, the vehicle should be taken to an
authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the Occupant Restraint
Controller (ORC) will determine whether to have the
Enhanced Accident Response System perform the
