Additional Factors Affecting System
Operation Safety belts help keep the passenger in position on the
seat during vehicle maneuvers and braking, which
helps the passenger sensing system maintain the
passenger airbag status. See “Safety Belts” and “Child
Restraints” in the Index for additional information
about the importance of proper restraint use.
If the shoulder portion of the belt is pulled out all the
way, the child restraint locking feature will be engaged.
This may unintentionally cause the passenger sensing
system to turn the airbag off for some adult size
occupants. If this happens, let the belt go back all the
way and start again.
A thick layer of additional material, such as a blanket or
cushion, or aftermarket equipment such as seat covers,
seat heaters, and seat massagers can affect how well the
passenger sensing system operates. We recommend
that you not use seat covers or other aftermarket
equipment except when approved by GM for your speci c
vehicle. See Adding Equipment to Your Airbag-Equipped
Vehicle on page 1-94 for more information about
modi cations that can affect how the system operates. The on indicator may be lit if an object, such as a
briefcase, handbag, grocery bag, laptop or other
electronic device, is put on an unoccupied seat.
If this is not desired remove the object from the seat.
{ CAUTION: Stowing of articles under the passenger seat or
between the passenger seat cushion and seatback
may interfere with the proper operation of the
passenger sensing system.

If you lose or damage your PASS-Key ®
III+ key, see
your dealer/retailer or a locksmith who can service
PASS-Key ®
III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle. Starting and Operating Your
Vehicle New Vehicle Break-In Notice: The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
Do not tow a trailer during break-in. See Towing
a Trailer on page 5-44 for the trailer towing
capabilities of the vehicle and more information.
Following break-in, engine speed and load can
be gradually increased.
2-24
Ignition Positions The ignition switch has
four different positions.
To shift out of P (Park), the ignition must be in ON/RUN
or ACC/ACCESSORY and the regular brake pedal must
be applied.
A (LOCK/OFF): This position locks the ignition. It may
also lock the steering wheel and automatic transmission.
The key can be removed in LOCK/OFF.
On vehicles with an automatic transmission, the shift
lever must be in P (Park) to turn the ignition switch to
LOCK/OFF.
The steering may bind with the wheels turned off center.
If this happens, move the steering wheel from right
to left while turning the key to ACC/ACCESSORY.
If this doesn’t work, then the vehicle needs service. Notice: Using a tool to force the key to turn in the
ignition could cause damage to the switch or break
the key. Use the correct key, make sure it is all the
way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer/retailer.
B (ACC/ACCESSORY): This position lets things like the
radio and the windshield wipers operate while the
engine is off. Use this position if the vehicle must be
pushed or towed.
C (ON/RUN): This position can be used to operate the
electrical accessories and to display some instrument
panel cluster warning and indicator lights. The switch
stays in this position when the engine is running.
The transmission is also unlocked in this position
on automatic transmission vehicles.
If you leave the key in the ACC/ACCESSORY or ON/
RUN position with the engine off, the battery could be
drained. You may not be able to start the vehicle if the
battery is allowed to drain for an extended period of time.
D (START): This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.
2-25
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
R (Reverse): Use this gear to back up.
Notice: Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to get out of snow, ice,
or sand without damaging the transmission, see If Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 5-31 .
N (Neutral): In this position, the engine does not connect
with the wheels. To restart when you are already moving,
use N (Neutral) only. Also, use N (Neutral) when the
vehicle is being towed.
{ CAUTION: Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is rmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed. Notice: Shifting out of P (Park) or N (Neutral) with
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.
D (Drive): This position is for normal driving. It provides
the best fuel economy. If you need more power for
passing, and you are:
Going less than about 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
By doing this, the vehicle shifts down to the next gear
and has more power.
D (Drive) can be used when towing a trailer, carrying a
heavy load, driving on steep hills, or for off-road driving.
You may want to shift the transmission to a lower gear
selection if the transmission shifts too often.
Downshifting the transmission in slippery road conditions
could result in skidding, see Skidding under Loss of
Control on page 5-12 .
2-30
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
Tow/Haul Mode
The vehicle has a tow/haul mode. The tow/haul mode
adjusts the transmission shift pattern to reduce shift
cycling, providing increased performance, vehicle control,
and transmission cooling when towing or hauling heavy
loads.
Press the button located on the end of the shift lever to
turn the tow/haul on or off. When the tow/haul is on,
a light on the instrument panel cluster will come on.
See Tow/Haul Mode Light on page 3-46 for more
information.
Also see “Tow Haul Mode” under Towing a Trailer on
page 5-44 for more information. The tow/haul mode works with the Autoride ®
feature, if
the vehicle has this, to enhance the ride when trailering or
with a loaded vehicle. See Autoride ®
on page 5-44 .
Grade Braking The Grade Braking shift modes can be activated by
pressing the button on the end of the shift control lever.
While in Range Selection Mode, Grade Braking is
deactivated allowing the driver to select a desired range
of gears.
Grade Braking is only active while the Tow/Haul Mode is
selected and you are not in the Range Selection Mode.
See “Tow/Haul Mode listed previously and Automatic
Transmission Operation on page 2-29 for more
information on the Range Selection Mode. Grade Braking
assists in maintaining desired vehicle speeds when
driving on downhill grades by automatically implementing
a shift schedule that utilizes the engine and transmission
to slow the vehicle. This reduces wear on the braking
system and increases control of the vehicle. Grade
Braking monitors vehicle speed, acceleration, engine
torque and brake pedal usage. Using this information, it
detects when the vehicle is on a downhill grade and the
driver desires to slow the vehicle by pressing the brake.
Also see Towing a Trailer on page 5-44 for more
information.
