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.

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.

(Continued)
Electronic Stability Control (ESC)
ESC enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying
the brake of the appropriate wheel(s) to counteract these
conditions. Engine power may also be reduced to help the
vehicle maintain the desired path.
Oversteer — when the vehicle is turning more than
appropriate for the steering wheel position.
 Understeer — when the vehicle is turning less than
appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the oversteer
or understeer condition. The ESC Activation/Malfunction Indicator Light located in
the instrument cluster will start to flash as soon as the ESC
system becomes active. The ESC Activation/Malfunction
Indicator Light also flashes when the 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.
ESC Operating Modes
Depending upon model and mode of operation, the
ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs.
WARNING!

Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

WARNING!

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 accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro -
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capabil -
ities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of
others.
 Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris -
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.

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

162SAFETY
NOTE:In a parking lot situation, oncoming vehicles can be
blocked by vehicles parked on either side. If the sensors
are blocked by other structures or vehicles, the system will
not be able to alert the driver.
Blind Spot Modes
Blind Spot Alert has three selectable modes of operation
that are available in the Uconnect system.
Blind Spot Alert Lights Only (Default Setting)
When operating in Lights Only mode, the BSM system will
provide a visual alert in the appropriate side view mirror
based on a detected object. However, when the system is
operating in Rear Cross Path (RCP) mode, the system will
respond with both visual and audible alerts when a
detected object is present. Whenever an audible alert is
requested, the radio is muted for the duration of the
chime. Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime mode,
the BSM system will provide a visual alert in the
appropriate side view mirror based on a detected object.
If the turn signal is then activated, and it corresponds to
an alert present on that side of the vehicle, an audible
chime will also be sounded. Whenever a turn signal and
detected object are present on the same side at the same
time, both the visual and audible alerts will be issued. In
addition to the audible alert the radio (if on) will also be
muted.
When the system is in RCP, the system shall respond with
both visual and audible alerts when a detected object is
present. Whenever an audible alert is requested, the radio
volume is reduced. Turn/hazard signal status is ignored;
the RCP state always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off, there will be no visual
or audible alerts from either the BSM or RCP systems.NOTE:The BSM system will store the current operating mode
when the vehicle is shut off. Each time the vehicle is
started the previously stored mode will be recalled and
used.
Blocked Sensor
If the system detects degraded performance due to
contamination or foreign objects, a message will warn you
of a blocked sensor and the warning indicators in side
view mirrors will be illuminated. The warning indicators will
remain illuminated until blockage clearing conditions are
met. First clear the fascia/bumper area around the sensors of the blockage. After removing the blockage,
reset the system by cycling the ignition from ON to OFF and
then back ON.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
FCW with Mitigation provides the driver with audible
warnings, visual warnings (within the instrument cluster
display), and may apply a brake jerk to warn the driver
when it detects a potential frontal collision. The warnings
and limited braking are intended to provide the driver with
enough time to react, avoid or mitigate the potential
collision.
NOTE:FCW monitors the information from the forward looking
sensors/cameras as well as the Electronic Brake
Controller (EBC), to calculate the probability of a forward
collision. When the system determines that a forward
collision is probable, the driver will be provided with
audible and visual warnings and may provide a brake jerk
warning.
If the driver does not take action based upon these
progressive warnings, then the system will provide a
limited level of active braking to help slow the vehicle and
mitigate the potential forward collision. If the driver reacts
to the warnings by braking and the system determines
that the driver intends to avoid the collision by braking but
has not applied sufficient brake force, the system will
compensate and provide additional brake force as
required.
WARNING!
Rear Cross Path Detection (RCP) is not a backup aid
system. It is intended to be used to help a driver detect
an oncoming vehicle in a parking lot situation. Drivers
must be careful when backing up, even when using
RCP. Always check carefully behind your vehicle, look
behind you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and blind spots
before backing up. Failure to do so can result in serious
injury or death.

23_GG_OM_EN_USC_t.book Page 162

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.

23_GG_OM_EN_USC_t.book Page 163

SAFETY165
Turning PEB On Or Off
NOTE:The default status of PEB is “On.” This allows the system
to warn you of a possible frontal collision with the pedes -
trian/cyclist.
The PEB button is located in the Uconnect Settings
Úpage 130.
To turn the PEB system off, push the Pedestrian
Emergency Braking OFF button.
To turn the PEB system back on, push the Warning Active
Braking button.

Changing the PEB 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 with a pedestrian/cyclist.

Changing the PEB status to “Off” deactivates the system,
so no warning or active braking will be available in case of
a possible frontal collision with a pedestrian/cyclist.
NOTE:The PEB system will retain the last setting selected by the
driver after ignition shut down. The system will not reset to
the default setting when the vehicle is restarted.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The TPMS will warn the driver of a low tire pressure based
on the vehicle recommended cold placard pressure.
The tire pressure will vary with temperature by
approximately 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature decreases, the
tire pressure will decrease. Tire pressure should always be
set based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven for
at least three hours, or driven less than 1 mile (1.6 km)
after a three hour period. The cold tire inflation pressure
must not exceed the maximum inflation pressure molded
into the tire sidewall. The tire pressure will also increase
as the vehicle is driven. This is normal and there should be
no adjustment for this increased pressure.
For more information on how to properly inflate the
vehicle’s tires, see
Úpage 246.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire. The TPMS will continue to
warn the driver of low tire pressure as long as the
condition exists, and will not turn off until the tire pressure
is at or above the recommended cold placard pressure.
NOTE:Once the low tire pressure warning (Tire Pressure
Monitoring System Warning Light) illuminates, you must
increase the tire pressure to the recommended cold
placard pressure in order for the Tire Pressure Monitoring
System Warning Light to turn off.
The system will automatically update and the Tire
Pressure Monitoring System Warning Light will turn off
once the system receives the updated tire pressures. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive this information.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of
33 psi (227 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn on
the Tire Pressure Monitoring System Warning Light.
Driving the vehicle may cause the tire pressure to rise to
approximately 28 psi (193 kPa), but the Tire Pressure
Monitoring System Warning Light will still be on. In this
situation, the Tire Pressure Monitoring System Warning
Light will turn off only after the tires are inflated to the
vehicle’s recommended cold placard pressure value
Úpage 275.
NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring System Warning Light off.
