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 6‑12.
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.
3-37
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 first line and the current gear will be
displayed on the second line. See
Driver Information
Center (DIC)
on page 4‑39and DIC Operation and
Displayson page 4‑40for 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 3‑39for
more information.
While using the DSC, cruise control and the tow/haul
mode can be used.

WARNING: (Continued)
even death. Never run the engine in an enclosed
area that has no fresh air ventilation. For more
information, seeEngine Exhaust on page 3‑44.
{WARNING:
It can be dangerous to get out of the vehicle if the
automatic transmission shift lever is not fully in
P (Park) with the parking brake firmly 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).
Follow the proper steps to be sure the vehicle will not
move. See Shifting Into Park on page 3‑41.
If parking on a hill and pulling a trailer, see Towing a
Trailer on page 6‑42.
Mirrors
Manual Rearview Mirror
Hold the inside rearview mirror in the center to move it
for a clearer view behind your vehicle. Adjust the mirror
to avoid glare from the headlamps behind you. Push the
tab forward for daytime use and pull it for nighttime use.
Automatic Dimming Rearview Mirror
This vehicle may have an automatic dimming inside
rearview mirror with OnStar®. It may also have
Intellibeam®. For more information on Intellibeam™, see
“Intellibeam™ Intelligent High‐Beam Headlamp Control
System” underExterior Lamps
on page 4‑10. For more
information on OnStar®, see the OnStar®owner's guide.
Automatic Dimming Mirror Operation
Automatic dimming reduces the glare of lights from
behind the vehicle. The dimming feature comes on and
the indicator light illuminates each time the vehicle is
started.
O(On/Off): Press to turn the dimming feature on or off.
Cleaning the Mirror
Do not spray glass cleaner directly on the mirror. Use a
soft towel dampened with water.

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
fluid, 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 Harness Package
The vehicle has a seven-pin universal heavy-duty trailer
connector attached to the rear bumper beam 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 wires are not
connected. They should be connected by your
dealer/retailer or a qualified service center.
If charging a remote (non-vehicle) battery, press the
tow/haul mode button 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, turn on the headlamps as a second way
to boost the vehicle system and charge the battery.
6-53
Jump Starting
If the vehicle's battery (or batteries) has run down, you
may want to use another vehicle and some jumper
cables to start your vehicle. Be sure to use the following
steps to do it safely.
{WARNING:
Batteries can hurt you. They can be dangerous
because:
.They contain acid that can burn you.
.They contain gas that can explode or ignite.
.They contain enough electricity to burn you.
If you do not follow these steps exactly, some or
all of these things can hurt you. Notice:
Ignoring these steps could result in costly
damage to the vehicle that would not be covered by
the warranty.
Trying to start the vehicle by pushing or pulling it
will not work, and it could damage the vehicle.
1. Check the other vehicle. It must have a 12-volt battery with a negative ground system.
Notice: If the other vehicle's system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not
touching each other. If they are, it could cause a
ground connection you do not want. You would
not be able to start your vehicle, and the bad
grounding could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put the automatic
transmission in P (Park) or a manual transmission
in Neutral before setting the parking brake. If you
have a four-wheel-drive vehicle, be sure the
transfer case is in a drive gear, not in Neutral.
