(Continued)
When Brake Service Mode work is complete, the following
steps must be followed to reset the parking brake system
to normal operation:

Ensure the vehicle is at a standstill.
 Press the brake pedal with moderate force.
 Apply the EPB Switch.
NOTE:A dedicated message will appear in the instrument cluster
display if Brake Service Mode cannot be deactivated.
AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while shifting out
of PARK.
WARNING!
You can be badly injured working on or around a motor
vehicle. Do only that service work for which you have
the knowledge and the right equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.
WARNING!
Never use the PARK (P) position as a substitute for
the parking brake. Always apply the parking brake
fully when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the gear
selector out of PARK with the brake pedal released.
Make sure the transmission is in PARK before exiting
the vehicle.
 It is dangerous to shift out of PARK or NEUTRAL (N) if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.
 The vehicle may not engage a newly selected gear
when shifting between PARK, REVERSE (R), or
DRIVE (D) if the vehicle is moving while shifting.
 Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always come to a
complete stop, then apply the parking brake, shift
the transmission into PARK, and turn the ignition
OFF. When the ignition is in the OFF position, the
transmission is locked in PARK, securing the vehicle
against unwanted movement.
 When leaving the vehicle, always make sure the igni -
tion is in the OFF position, remove the key fob from
the vehicle, and lock the vehicle.
WARNING!
 Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be seri -
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
transmission gear selector.
 Do not leave the key fob in or near the vehicle (or in
a location accessible to children), and do not leave
the ignition in the ON/RUN position. A child could
operate power windows, other controls, or move the
vehicle.
CAUTION!
Damage to the transmission may occur if the following
precautions are not observed:
Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
 Do not shift between PARK, REVERSE, NEUTRAL, or
DRIVE when the engine is above idle speed.
 Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal.
WARNING!

86STARTING AND OPERATING
IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK (P) before
the ignition can be turned to the OFF position. This helps
the driver avoid inadvertently leaving the vehicle without
placing the transmission in PARK. This system maintains
lock of the transmission in PARK whenever the ignition is
in the OFF position.
BRAKE/TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI that holds the
transmission gear selector in PARK (P) unless the brakes
are applied. To shift the transmission out of PARK, the
ignition must be in the ON/RUN position (whether the
engine is running or not), and the brake pedal must be
pressed. The brake pedal must also be pressed to shift
from NEUTRAL (N) into DRIVE (D) or REVERSE (R) when the
vehicle is stopped or moving at low speeds.
9-SPEED AUTOMATIC TRANSMISSION
The transmission gear range (PRND) is displayed both
beside the gear selector and in the instrument cluster.
To select a gear range, push the lock button on the gear
selector and move the selector rearward or forward. You
must also press the brake pedal to shift the transmission
out of PARK (P) (or NEUTRAL (N), when the vehicle is
stopped or moving at low speeds). Select the DRIVE (D)
range for normal driving.
NOTE:
 The transmission electronics are self-calibrating;
therefore, the first few shifts on a new vehicle may be
somewhat abrupt. This is a normal condition, and
precision shifts will develop within a few hundred
miles (kilometers).
 In the event of a mismatch between the gear selector
position and the actual transmission gear (for example,
driver selects REVERSE (R) while driving forward), the
position indicator will blink continuously until the
selector is returned to the proper position, or the
requested shift can be completed.
The electronically controlled transmission adapts its shift
schedule based on driver inputs, along with environmental
and road conditions.
The 9-speed transmission has been developed to meet
the needs of current and future FWD/AWD vehicles.
Software and calibration are refined to optimize the
customer’s driving experience and fuel economy. By
design, some vehicle and driveline combinations utilize
NINTH gear only in very specific driving situations and
conditions.
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when shifting
between these gears.

Gear Selector

Gear Ranges
Do not press the accelerator pedal when shifting out of
PARK or NEUTRAL.
NOTE:After selecting any gear range, wait a moment to allow the
selected gear to engage before accelerating. This is espe -
cially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when exiting the vehicle in this
range.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK, otherwise the load on
the transmission locking mechanism may make it difficult
to move the gear selector out of PARK. As an added
precaution, turn the front wheels toward the curb on a
downhill grade and away from the curb on an uphill grade.

23_GG_OM_EN_USC_t.book Page 86

STARTING AND OPERATING87
When exiting the vehicle, always:

1. Apply the parking brake.

2. Shift the transmission into PARK.
3. Turn the engine off.
4. Remove the key fob from the vehicle.
NOTE:Block the wheels with a wedge or a stone if the vehicle is
parked on a steep slope.
The following indicators should be used to ensure that you
have properly engaged the transmission into the PARK
position:
When shifting into PARK, push the lock button on the
gear selector, and firmly move the selector all the way
forward until it stops and is fully seated.
 Look at the transmission gear position display and
verify that it indicates the PARK position (P).
 With the brake pedal released, verify that the gear
selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Apply the parking brake and shift the
transmission into PARK if you must exit the vehicle.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission
automatically upshifts through all forward gears. If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the
transmission shift schedule, reduce engine torque, and/or
expand the range of torque converter clutch engagement.
This is done to prevent transmission damage due to
overheating.
If the transmission becomes extremely hot, the
Transmission Temperature Warning Light may illuminate,
and the transmission may operate differently until the
transmission cools down.
During cold temperatures, transmission operation may be
modified depending on engine and/or transmission
temperature as well as vehicle speed. This feature
improves warm-up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch (and shifts into EIGHTH or NINTH gear),
are inhibited until the engine and/or transmission is
warm. Normal operation will resume once the
temperature(s) have risen to a suitable level.
TRANSMISSION LIMP HOME MODE
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in a fixed gear, or may remain in NEUTRAL
(N). The Malfunction Indicator Light (MIL) may be
illuminated. Limp Home Mode may allow the vehicle to be
driven to an authorized dealer for service without
damaging the transmission.
CAUTION!

Before moving the transmission gear selector out of
PARK, you must turn the ignition to the ON/RUN posi -
tion, and also press the brake pedal. Otherwise,
damage to the gear selector could result.
 DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range, as this can
damage the drivetrain.WARNING!
Do not coast in NEUTRAL and never turn off the ignition
to coast down a hill. These are unsafe practices that
limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.

88STARTING AND OPERATING
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK (P), if possible. If
not, shift the transmission to NEUTRAL.
3. Push and hold the ignition until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to
normal operation.
NOTE:Even if the transmission can be reset, we recommend that
you visit an authorized dealer at your earliest possible
convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission.
If the transmission cannot be reset, authorized dealer
service is required.
TORQUE CONVERTER CLUTCH
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages
automatically at calibrated speeds. This may result in a
slightly different feeling or response during normal
operation in the upper gears. When the vehicle speed
drops or during some accelerations, the clutch
automatically disengages.
NOTE:The torque converter clutch will not engage until the
engine and/or transmission is warm (usually after 1 to
3 miles [2 to 5 km] of driving). Because the engine speed
is higher when the torque converter clutch is not engaged,
it may seem as if the transmission is not shifting properly
when the vehicle is cold. This is normal. The torque
converter clutch will function normally once the powertrain
is sufficiently warm.
ALL-WHEEL DRIVE (AWD)
This feature provides on-demand All-Wheel Drive (AWD).
The system is automatic with no driver inputs or additional
driving skills required. Under normal driving conditions,
the front wheels provide most of the traction. If the front
wheels begin to lose traction, power is shifted
automatically to the rear wheels. The greater the front
wheel traction loss, the greater the power transfer to the
rear wheels.
Additionally, on dry pavement under heavy throttle input
(where one may have no wheel spin), torque will be sent to
the rear in a preemptive effort to improve vehicle launch
and performance characteristics.
SPORT MODE — IF EQUIPPED
Your vehicle is equipped with a SPORT Mode feature. The
engine, transmission, and steering systems are all set to
their SPORT settings. SPORT Mode will provide improved
throttle response and modified transmission shift points
for an enhanced driving experience, as well as greater
amount of steering feel.
This mode may be activated and deactivated by pushing
the SPORT button on the steering wheel. For PHEV
versions the SPORT button is located below the STOP/
START button.
POWER STEERING

The electric power steering system will provide increased
vehicle response and ease of maneuverability. The electric
power steering system adapts to different driving conditions.

If the “SERVICE POWER STEERING” or “POWER
STEERING ASSIST OFF - SERVICE SYSTEM”
message and a steering wheel icon display on
the instrument cluster, it indicates that the
vehicle needs service. It may be necessary to perform the
recalibration maneuver by turning the steering wheel from
full left position to full right position. If the problem is still
present, take the vehicle to an authorized dealer for
service. It is likely the vehicle has lost power steering
assistance
Úpage 66.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire size
may cause failure of the power transfer unit.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.

23_GG_OM_EN_USC_t.book Page 88

STARTING AND OPERATING89
If the “POWER STEERING SYSTEM HOT -
PERFORMANCE MAY BE LIMITED” message
and a steering wheel icon display on the
instrument cluster, it indicates that extreme
steering maneuvers may have occurred, which caused an
over temperature condition in the electric power steering
system. You will lose power steering assistance
momentarily until the over temperature condition no
longer exists. Once driving conditions are safe, pull over
and let the vehicle idle for a few moments until the light
turns off
Úpage 66.
NOTE:
 Even if the power steering system is no longer opera -
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
 If the condition persists, see an authorized dealer for
service.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is designed to reduce fuel
consumption. The system will stop the engine
automatically during a vehicle stop if the required
conditions are met. Releasing the brake pedal or pressing
the accelerator pedal will automatically restart the engine.
This vehicle has been upgraded with a heavy-duty starter,
enhanced battery, and other upgraded engine parts, to
handle the additional engine starts.
AUTOSTOP MODE
The Stop/Start feature is enabled after every normal
customer engine start. At that time, the system will go into
STOP/START READY.
To Activate The Autostop Mode, The Following Must Occur:
The system must be in STOP/START READY state. A
“STOP/START READY” message will be displayed in the
instrument cluster display within the Stop/Start
section
Úpage 66.
 The vehicle must be completely stopped.
 The gear selector must be in a forward gear and the
brake pedal pressed.
The engine will shut down, the tachometer will move to the
zero position, and the Stop/Start telltale will illuminate
indicating you are in Autostop. Customer settings will be
maintained upon return to an engine-running condition.
POSSIBLE REASONS THE ENGINE DOES
N
OT AUTOSTOP
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
Detailed information about the operation of the Stop/Start
system may be viewed in the instrument cluster display
Stop/Start Screen. In the following situations the engine
will not stop:
 Driver’s seat belt is not buckled.
 Driver’s door is not closed.
 Battery temperature is too warm or cold. 
Battery charge is low.
 The vehicle is on a steep grade.
 Cabin heating or cooling is in process and an accept -
able cabin temperature has not been achieved.
 HVAC is set to full defrost mode at a high blower speed.
 HVAC is set to MAX A/C.
 Engine has not reached normal operating temperature.
 The transmission is not in a forward gear.
 Hood is open.
 Brake pedal is not pressed with sufficient pressure.

STARTING AND OPERATING93
(Continued)
ACC will allow you to keep Cruise Control engaged in light
to moderate traffic conditions without the constant need
to reset your speed. ACC utilizes a radar sensor and a
forward facing camera designed to detect a vehicle
directly ahead of you to maintain a set speed.
NOTE:

If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or accelerate (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead.
 Any chassis/suspension or tire size modifications to
the vehicle will affect the performance of the Adaptive
Cruise Control and Forward Collision Warning system.
Adaptive Cruise Control (ACC) Operation
The buttons on the left side of the steering wheel operate
the ACC system.

Adaptive Cruise Control Buttons

Adaptive Cruise Control (ACC) System
Status
The instrument cluster display will show the current ACC
system settings. The information it displays depends on
ACC system status.
Push the Mode button to enable the ACC system.
WARNING!
Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driver involve -
ment. It is always the driver’s responsibility to be
attentive of road, traffic, and weather conditions,
vehicle speed, distance to the vehicle ahead 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 and death or serious personal injury.
 The ACC system:
 Does not react to pedestrians, oncoming vehi -
cles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
 Cannot take street, traffic, and weather condi -
tions into account, and may be limited upon
adverse sight distance conditions.
 Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.
You should turn the ACC system off:
 When driving in fog, heavy rain, heavy snow, sleet,
heavy traffic, and complex driving situations
(i.e., in highway construction zones).
 When entering a turn lane or highway off-ramp; when
driving on roads that are winding, icy, snow-covered,
slippery, or have steep uphill or downhill slopes.
 When towing a trailer up or down steep slopes.
 When circumstances do not allow safe driving at a
constant speed.

98STARTING AND OPERATING
LANE CHANGING
ACC may not detect a vehicle until it is completely in the
lane in which you are traveling. In the following lane
changing example, ACC has not yet detected the vehicle
changing lanes and it may not detect the vehicle until it's
too late for the ACC system to take action. ACC may not
detect a vehicle until it is completely in the lane. There
may not be sufficient distance to the lane-changing
vehicle. Always be attentive and ready to apply the brakes
if necessary.

Lane Changing Example

NARROW VEHICLES
Some narrow vehicles traveling near the outer edges of
the lane or edging into the lane are not detected until they
have moved fully into the lane. There may not be sufficient
distance to the vehicle ahead.

Narrow Vehicle Example

STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects or vehicles. For
example, ACC will not react in situations where the vehicle
you are following exits your lane and the vehicle ahead is
stopped in your lane. It will consider this stopped vehicle a
stationary object as it did not previously detect movement
from it. Always be attentive and ready to apply the brakes
if necessary.
