The power liftgate can be power opened and closed in
the following ways:
Press and hold the power liftgate button on the
Remote Keyless Entry (RKE) transmitter until
the liftgate starts moving. Remote Keyless Entry
(RKE) System Operation on page 2-5 for more
information.
Pressing the liftgate button on the overhead
console.
Pressing the touchpad switch on the outside liftgate
handle.
Pressing the buttons, or touchpad switch a second time
while the liftgate is moving reverses the direction.
l : The liftgate can also be closed by pressing the
power liftgate button next to the liftgate latch.
Press the button a second time during liftgate operation
to reverse that operation.
The power liftgate may be temporarily disabled under
extreme temperatures, or under low battery conditions.
If this occurs, the liftgate can still be operated manually.
If you shift the transmission out of PARK (P) while the
power function is in progress, the liftgate power function
will continue to completion. If you shift the transmission
out of PARK (P) and accelerate before the power liftgate
latches closed, the liftgate may reverse to the open
position. Cargo could fall out of the vehicle. Always make
sure the power liftgate is closed and latched before you
drive away. If you power open the liftgate and the liftgate support
struts have lost pressure, the lights will ash and a chime
will sound. The liftgate will stay open temporarily, then
slowly close. See your dealer/retailer for service before
using the liftgate.
Obstacle Detection Features If the liftgate encounters an obstacle during a power open
or close cycle, a warning chime will sound and the liftgate
will automatically reverse direction to the full closed or
open position. After removing the obstruction, the power
liftgate operation can be used again. If the liftgate
encounters multiple obstacles on the same power cycle,
the power function will deactivate, and you must manually
open or close the liftgate. The REAR ACCESS OPEN
warning message in the Driver Information Center (DIC)
will indicate that the liftgate is open. After removing the
obstructions, manually open the liftgate to the full open
position or close the liftgate to the fully closed and latched
position. The liftgate will now resume normal power
operation.
Your vehicle has pinch sensors located on the side edges
of the liftgate. If an object is caught between the liftgate
and the body and presses against this sensor, the liftgate
will reverse direction and open fully. The liftgate will
remain open until it is activated again or closed manually.
Do not force the liftgate open or closed during a power
cycle.
2-15
Retained Accessory Power (RAP) The following vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
OnStar ®
System (if equipped)
Sunroof (if equipped)
These features work when the key is in ON/RUN or
ACC/ACCESSORY. Once the key is turned from
ON/RUN to LOCK/OFF, the windows and sunroof
continue to work up to 10 minutes until any door
is opened. The radio continues to work for up to
10 minutes or until the driver door is opened.
Starting the Engine If the vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
Move the shift lever to P (Park) or N (Neutral).
The engine will not start in any other position.
To restart the engine when the vehicle is are already
moving, use N (Neutral) only.
Notice: Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could damage the
transmission. Shift to P (Park) only when the vehicle
is stopped. Starting Procedure 1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts, let go
of the key. The idle speed will go down as the engine
gets warm. Do not race the engine immediately after
starting it. Operate the engine and transmission
gently to allow the oil to warm up and lubricate all
moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START for many seconds, cranking will be stopped
after 15 seconds to prevent cranking motor damage.
To prevent gear damage, this system also prevents
cranking if the engine is already running. Engine
cranking can be stopped by turning the ignition
switch to the ACC/ACCESSORY or LOCK/OFF
position.
Notice: Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.
2-26
Automatic Transmission Operation If the vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
The vehicle has a Hydra-Matic ®
6L80 automatic
transmission, and has an electronic shift position
indicator within the instrument panel cluster.
The electronic shift position indicator displays
when the shift lever is moved out of P (Park).
There are several different positions for the shift lever.
P (Park): This position locks the rear wheels. It is the
best position to use when you start the engine because
the vehicle cannot move easily. When parked on a hill, especially when the vehicle has
a heavy load, you may notice an increase in the effort to
shift out of P (Park). See Torque Lock (Automatic
Transmission) under Shifting Into Park on page 2-36 for
more information.
{ CAUTION: It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
rmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). See Shifting Into
Park on page 2-36 . If you are pulling a trailer, see
Towing a Trailer on page 5-44 .
2-29
M (Manual Mode): This position lets drivers select the
range of gears appropriate for current driving conditions.
See Driver Shift Control (DSC) later in this section.
Notice: Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transmission. The repair will not be
covered by the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
The vehicle has a shift stabilization feature that adjusts
the transmission shifting to the current driving conditions
in order to reduce rapid upshifts and downshifts. This shift
stabilization feature is designed to determine, before
making an upshift, if the engine will be able to maintain
vehicle speed by analyzing things such as vehicle speed,
throttle position and vehicle load. If the shift stabilization
feature determines that a current vehicle speed cannot be
maintained, the transmission does not upshift and instead
holds the current gear. In some cases, this may appear to
be a delayed shift, however the transmission is operating
normally. The vehicle’s transmission uses adaptive shift controls
that compares key shift parameters to pre-programmed
ideal shifts stored in the transmissions computer.
The transmission constantly makes adjustments to
improve vehicle performance according to how the
vehicle is being used, such as with a heavy load or when
temperature changes. During this adaptive shift controls
process, shifting may feel different as the transmission
determines the best settings.
When temperatures are very cold, the Hydra-Matic ®
6L80 automatic transmission’s gear shifting may
be delayed providing more stable shifts until the engine
warms up. Shifts may be more noticeable with a cold
transmission. This difference in shifting is normal.
2-31
Driver Shift Control (DSC)
The vehicle has Driver Shift Control (DSC). DSC
controls the vehicle’s transmission and vehicle speed
while driving down hill or towing a trailer by allowing you
to select a desired range of gears. To use this feature, do the following:
1. Move the shift lever to the M (Manual Mode).
2. Press the plus/minus button, to upshift or downshift
selecting the desired range of gears for current
driving conditions.
The DIC display will show the message MANUAL SHIFT
on the rst line and the current gear will be displayed on
the second line. See Driver Information Center (DIC) on
page 3-47 and DIC Operation and Displays on page 3-48
for more information. The number displayed in the DIC is
the highest gear that can be used. However, the vehicle
can automatically shift to lower gears as it adjusts to
driving conditions. This means that all gears below
that number are available. When 5 (Fifth ) is selected,
1 (First) through 5 (Fifth) gears are automatically shifted
by the vehicle, but 6 (Sixth) cannot be used until the
plus/minus button located on the steering column lever
is used to change to the gear.
Grade Braking is not available when the Driver Shift
Control is active. See Tow/Haul Mode on page 2-33 for
more information.
While using the DSC, cruise control and the tow/haul
mode can be used.
2-32
Headlamps on Reminder If a door is open, a reminder chime will sound when
the headlamps or parking lamps are manually turned on
and the key is out of the ignition. To turn off the chime,
turn the headlamp switch to off or AUTO and then back
on, or close and re-open the door. In the AUTO mode,
the headlamps turn off once the ignition is in LOCK/OFF
or may remain on until the headlamp delay ends
(if enabled in the DIC). See “Exit Lighting” under
DIC Vehicle Customization on page 3-65 .
Daytime Running Lamps (DRL) Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required
on all vehicles rst sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on.
The exterior lamps control is in AUTO.
The transmission is not in P (Park).
The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, instrument panel lights,
and other lamps will not be on. When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
To turn off the DRL lamps, turn the exterior
lamps control to the OFF position and then release.
For vehicles rst sold in Canada, the transmission must
be in the P (Park) position, before the DRL lamps can
be turned off.
Automatic Headlamp System When it is dark enough outside, the automatic headlamp
system turns on the headlamps at the normal brightness,
along with the taillamps, sidemarker, parking lamps,
and the instrument panel lights. The radio lights will
also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then release
it. For vehicles rst sold in Canada, the transmission
must be in the P (Park) position, before the automatic
headlamp system can be turned off.
The vehicle has a light sensor located on the top of the
instrument panel in the defroster grille that regulates
when the automatic headlamps turn on. Do not cover
the sensor or the headlamps will come on whenever
the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
3-21
Maintenance When Trailer Towing The vehicle needs service more often when pulling a
trailer. See this manual’s Maintenance Schedule or Index
for more information. Things that are especially important
in trailer operation are automatic transmission uid,
engine oil, axle lubricant, belts, cooling system and brake
system. It is a good idea to inspect these before and
during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Trailer Wiring Harness Heavy-Duty Trailer Wiring Package
The vehicle is equipped with the seven-wire trailer
towing harness. This harness with a seven-pin universal
heavy-duty trailer connector is attached to the rear
bumper beam. It is located next to the integrated trailer
hitch. The seven-wire harness contains the following trailer
circuits:
Yellow: Left Stop/Turn Signal
Dark Green: Right Stop/Turn Signal
Brown: Taillamps
White: Ground
Light Green: Back-up Lamps
Red w/ Black Stripe: Battery Feed*
Dark Blue: Trailer Brake*
*The fuses for these two circuits are installed in the
underhood electrical center, but the circuits are
not connected. They should be installed by your dealer
or a quali ed service center.
If charging a remote (non-vehicle) battery, press the
Tow/Haul mode button, if equipped, located at the end of
the shift lever. This will boost the vehicle system voltage
and properly charge the battery. If the trailer is too light
for Tow/Haul mode, or the vehicle is not equipped with
Tow/Haul, turn on the headlamps as a second way to
boost the vehicle system and charge the battery.
