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 while towing or
hauling heavy loads.
Press the button located on the instrument panel to the
right of the steering wheel to turn tow/haul on or off. While
tow/haul is on, a light on the instrument panel cluster
comes on.
SeeTow/Haul Mode Light on page 3-44for more
information.
Also see “Tow Haul Mode” underTowing a Trailer on
page 4-55for more information.
Grade Braking
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 andAutomatic
Transmission Operation on page 2-32for 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 truck is on a downhill grade and the
driver desires to slow the vehicle by pressing the brake.
Also seeTowing a Trailer on page 4-55for more

OnStar Virtual Advisor
OnStar Virtual Advisor is a feature of OnStar
Hands-Free Calling that uses minutes to access
location-based weather, local traffic reports, and stock
quotes. Press the phone button and give a few simple
voice commands to browse through the various topics.
See the OnStar Owner’s Guide for more information.
This feature is only available in the continental U.S.
OnStar Steering Wheel Controls
This vehicle may have a Talk/Mute button that can
be used to interact with OnStar Hands-Free Calling.
SeeAudio Steering Wheel Controls on page 3-129
for more information.
On some vehicles, the mute button can be used to
dial numbers into voice mail systems, or to dial phone
extensions. See the OnStar Owner’s Guide for more
information.
How OnStar Service Works
The OnStar system can record and transmit vehicle
information. This information is automatically sent to an
OnStar Call Center when the OnStar button is pressed,
the emergency button is pressed, or if the airbags or
AACN system deploy. This information usually includes
the vehicle’s GPS location and, in the event of a crash,
additional information regarding the crash that the vehicle
was involved in (e.g. the direction from which the vehicle
was hit). When the Virtual Advisor feature of OnStar
Hands-Free Calling is used, the vehicle also sends
OnStar the vehicle’s GPS location so they can provide
services where it is located.
OnStar service cannot work unless the vehicle is in a
place where OnStar has an agreement with a wireless
service provider for service in that area. OnStar service
also cannot work unless the vehicle is in a place where
the wireless service provider OnStar has hired for that
area has coverage, network capacity and reception when
the service is needed, and technology that is compatible
with the OnStar service. Not all services are available
everywhere, particularly in remote or enclosed areas,
or at all times.

Cruise Control
{CAUTION:
Cruise control can be dangerous where you cannot
drive safely at a steady speed. So, do not use the
cruise control on winding roads or in heavy traffic.
Cruise control can be dangerous on slippery roads.
On such roads, fast changes in tire traction can
cause excessive wheel slip, and you could lose
control. Do not use cruise control on slippery roads.
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. This can really help on long trips.
Cruise control does not work at speeds below about
25 mph (40 km/h).
When the brakes are applied, cruise control is
turned off.
If the vehicle has the StabiliTrak
®system or Traction
Control system (TCS) and begins to limit wheel spin
while you are using cruise control, the cruise control
automatically disengages. SeeStabiliTrak
®System on
page 4-6orTraction Control System (TCS) on page 4-9.
When road conditions allow the cruise control to be safely
uses again, it can be turned back on.The cruise control buttons
are located on the left side
of the steering wheel.
T(On/Off):Press to turn the system on or off.
The indicator light on the button turns on when cruise
control is on and turns off when cruise control is off.
+ RES (Resume/Accelerate):Press to make the
vehicle accelerate or resume to a previously set speed.
SET−(Set/Coast):Press to set the speed or make
the vehicle decelerate.
[(Cancel):Press to cancel cruise control without
erasing the set speed from memory.

Setting Cruise Control
Cruise control will not work if the parking brake is set or
if the master cylinder brake uid level is low.
The cruise control light on the instrument panel cluster
comes on after the cruise control has been set to
the desired speed.
{CAUTION:
If you leave your cruise control on when you are
not using cruise, you might hit a button and go
into cruise when you do not want to. You could be
startled and even lose control. Keep the cruise
control switch off until you want to use cruise
control.
1. Press
T.
2. Get up to the desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
If the cruise control is set at a desired speed and then
the brake is applied, this shuts off the cruise control.
But it does not need to be reset.
Once the vehicle is driving about 25 mph (40 km/h) or
more, press the +RES button on the steering wheel.
The vehicle will return to the previously set speed and
stay there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise control:
Press and hold the +RES button on the steering
wheel until the desired speed is reached, then
release it.
