Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along
with the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:

{CAUTION:
It can be dangerous to drive with the cargo
area covered and the tailgate and the midgate®
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the cargo
covers on and the tailgate and midgate
®open
or if electrical wiring or other cable
connections must pass through the seal
between the body and the midgate
®:
Make sure all windows are shut.Turn the fan on your heating or cooling
system to its highest speed on the setting
that brings in outside air. This will force
outside air into your vehicle. SeeDual
Automatic Climate Control System on
page 3-22.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-37.
The midgate
®allows you to extend the length of your
vehicle’s cargo area into the cab.
Lowering the Midgate®
The midgate®window must be completely lowered for
the midgate®to be lowered. See “Midgate®Window”
underPower Windows on page 2-18.
Both the midgate
®and the midgate®window can be
lowered while the ignition is in either RUN or
ACCESSORY, or while in Retained Accessory Power
(RAP) mode. SeeRetained Accessory Power (RAP) on
page 2-25for more information.

2-12

Running the Engine While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-37.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard. See
Winter Driving on page 4-46.
{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your 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 your
vehicle will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
2-38

Outside Heated Mirrors
If the vehicle has heated
mirrors, the button to turn
this function on or off
is located on the climate
control panel.
Press this button to warm the driver’s and passenger’s
outside rearview mirrors to help clear them of ice,
snow, and condensation.
With a rear window defogger, the heated mirrors will
come on when this button is pressed. See “Rear
Window Defogger” underDual Automatic Climate
Control System on page 3-22for more information.
Outside Automatic Dimming Mirror
with Curb View Assist
If the vehicle has this feature, the driver’s outside mirror
adjusts for the glare of the headlamps behind you.
SeeAutomatic Dimming Rearview Mirror with OnStar
®,
Compass and Temperature Display on page 2-41.
The vehicle’s outside mirrors can also perform a curb
view assist mirror function. This causes the passenger’s
and/or driver’s mirror to tilt to a preselected position
when the vehicle is in REVERSE (R). This feature may
be useful in viewing the curb when parallel parking.
When the vehicle is shifted out of REVERSE (R) and a
short delay has occurred, the passenger’s and/or
driver’s mirror will return to its original position.
To change the preselected tilt position, adjust the
mirrors to the desired position while the vehicle is in
REVERSE (R). When the vehicle is shifted out of
REVERSE (R), this new position is saved in memory as
the tilt position.
This feature can be enabled/disabled through the Driver
Information Center. SeeDIC Vehicle Customization
on page 3-55for more information.

Ashtray(s) and Cigarette Lighter
If your vehicle has an ashtray, it is removable and ts
into the front cupholder. Pull up on the ashtray door
to open it.
Notice:If you put papers, pins, or other ammable
items in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage your vehicle. Never put ammable items in
the ashtray.
To remove the ashtray, pull it out from the console. To
reinstall the ashtray, slide it back to the original position.
To use the cigarette lighter, if equipped, push it in all
the way, and let go. When it’s ready, it will pop back out
by itself.
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
Climate Controls
Dual Automatic Climate Control
System
With this system, you can control the heating, cooling
and ventilation in your vehicle.
You can select different climate control settings for the
driver and passengers.
3-22

Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change to
show the current driver’s set temperature, delivery
mode and fan speed. Press the AUTO button again
within ve seconds to display the passenger’s set
temperature.
If the driver and passenger’s temperature
settings are not the same, the opposite side
temperature setting will be displayed for an
additional ve seconds. To make the passenger’s
temperature the same as the driver’s press and hold
the AUTO button for about four seconds.
When auto is selected, the air conditioning operation
and air inlet will be automatically controlled. The
air conditioning compressor will run when the
outside temperature is over about 40°F (4°C). The
air inlet will normally be set to outside air. If it’s
hot outside, the air inlet may automatically switch to
recirculate inside air to help quickly cool down
your vehicle. The light on the button will illuminate
in recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F (23°C)
temperature setting and allow about 20 minutes
for the system to regulate. Turn the driver’s orpassenger’s side temperature knob to adjust the
temperature setting as necessary. If you choose the
temperature setting of 60°F (15°C) the system
will remain at the maximum cooling setting. If you
choose the temperature setting of 90°F (32°C)
the system will remain at the maximum heat setting.
Choosing either maximum setting will not cause
the vehicle to heat or cool any faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield. This
sensor regulates air temperature based on sun
load, and also turns on your headlamps.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm air is
available. The length of delay depends on the
engine coolant temperature. Pressing the fan switch
will override this delay and change the fan to a
selected speed.
9(Off):Press this button to turn off the entire climate
control system. Outside air will still enter the vehicle, and
will be directed to the oor. This direction can be changed
by pressing the mode button. The temperature can also
be adjusted using either temperature knob. Press the up
or down arrows on the fan switch, the defrost button, the
AUTO button, or the air conditioning button to turn the
system on when it is off.
