automatically shifting into P (Park), check to
see if the P (Park) button on top of the shift
lever is stuck. To operate the vehicle, hold
the shift lever in the desired gear,
R (Reverse) or D (Drive), until vehicle speed
exceeds 15 km/h (10 mph), then release the
shift lever.
R : Use this gear to back up.
If the vehicle is shifted from either
R (Reverse) to D (Drive) or M (Manual Mode),
or M (Manual Mode) or D (Drive) to

2. Shift to the desired gear.
3. After releasing the shift lever, it will return to the center position.
At low vehicle speeds, R (Reverse) can be
used to rock the vehicle back and forth to
get out of snow, ice, or sand without
damaging the transmission. See If the
Vehicle Is Stuck 0169.
N : In this position, the engine does not
connect with the wheels. To restart the
engine when the vehicle is already moving,
use N (Neutral) only.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is firmly on
the brake pedal, the vehicle could move
very rapidly. You could lose control and

Warning (Continued)
hit people or objects. Do not shift into a
drive gear while the engine is running at
high speed.
Caution

the engine running at high speed may
damage the transmission. The repairs
would not be covered by the vehicle
warranty. Be sure the engine is not
running at high speed when shifting the
vehicle.
The vehicle is not designed to stay in
N (Neutral) for more than five minutes.

188 Driving and Operating
Before leaving the vehicle, check the red
parking brake status light to ensure that the
parking brake is applied.
EPB Apply
To apply the EPB:1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The red parking brake status light will flash
and then stay on once the EPB is fully
applied. If the red parking brake 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 parking brake status light
is flashing. See your dealer.
If the amber service parking brake warning
light is on, press the EPB switch. Continue to
hold the switch until the red parking brake
status light remains on. If the amber service
parking brake 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 at the request of 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 ignition on or to accessory mode.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the red parking
brake status light is off.
If the amber service parking brake 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 0250.
Automatic EPB Release
The EPB will automatically release 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

objects when entering or exiting a curve.
This is normal operation. The vehicle does
not need service.
Other Vehicle Lane Changes
ACC will not detect a vehicle ahead until it
is completely in the lane. The brakes may
need to be manually applied.
Objects Not Directly in Front of Your Vehicle
The detection of objects in front of the
vehicle may not be possible if:
.The vehicle or object ahead is not within
your lane.
.The vehicle ahead is shifted, not centered,
or is shifted to one side of the lane.
Driving in Narrow Lanes
Vehicles in adjacent traffic lanes or roadside
objects may be incorrectly detected when
located along the roadway. Do Not Use ACC on Hills
Do not use ACC when driving on steep hills
as ACC may not detect a vehicle ahead.
Towing with ACC
If equipped when, towing a trailer, ACC
driving characteristics such as following gap,
acceleration rates and braking rates may be
modified to provide a better towing
experience.
ACC is not recommended with vehicles
equipped with aftermarket trailer brake
controllers. Aftermarket trailer brake
controllers may not activate the trailer
brakes while ACC is engaged. Aftermarket
trailer brake controller manual engagement
will not disable ACC.
ACC may be used when towing a trailer
when trailer attached is within GM-approved
allowable size and weight limits. See
Trailer
Towing 0253.
Use Tow/Haul mode when driving down
steep hills or mountain grades, or when
hauling heavy loads. See Driver Mode
Control 0190.
ACC maintains the set speed when driving
uphill and downhill while towing a trailer.
However, ACC may make a slight change to
the cruise speed while driving on moderate
hills if the combined vehicle and trailer
weight is close to the maximum Gross
Combined Weight Rating (GCWR). See Trailer
Towing 0253. This is normal ACC operation
and is necessary to maintain the set speed.
ACC may disengage if it detects that the
brake temperature exceeds the normal
range.
Disengaging ACC
There are three ways to disengage ACC:
.Step lightly on the brake pedal.
.Press*.
.PressJ.

Stationary or Very Slow-Moving Objects;
Cross-Traffic
{Warning
Super Cruise is not a crash avoidance
system and will not steer or brake to
avoid a crash. Super Cruise does not steer
to prevent a crash with stopped or
slow-moving vehicles. You must supervise
the driving task and may need to steer
and brake to prevent a crash, especially
in stop-and-go traffic or when a vehicle
suddenly enters your lane. Always pay
attention when using Super Cruise.
Failure to do so could result in a crash
involving serious injury or death.
Curves in the Road
{Warning
The vehicle could drift out of your lane of
travel. To prevent crashes, always be
ready to manually steer. Super Cruise
may not detect your lane on curves in
the road. Super Cruise may not detect
the markings that show your lane. You
may not have time to react to a vehicle (Continued)
Warning (Continued)
in the lane next to your vehicle while on
curves in the road. Super Cruise may
hand control back to the driver more
often driving around a sharp curve while
towing a trailer.
Super Cruise may operate differently in
sharp curves. It may drift out of your lane
of travel if the curve is too sharp.
When entering a curve, Super Cruise may
not detect the lane markings and may not
adjust the steering enough to stay in your
lane of travel. When this happens, you will
need to steer the vehicle. Super Cruise may detect other lane
markings that are not in your lane and may
or may not steer appropriately to maintain
your lane.
Super Cruise may occasionally provide an
alert and/or steering that is considered
unnecessary. It could respond to lane
markings in different lanes, signs, guardrails,
and other stationary objects when entering
or exiting a curve. This is normal operation.
The vehicle does not need service.
