Adjustable Throttle and Brake Pedal
On vehicles with this feature, you can change the
position of the throttle and brake pedals.
No adjustment to the pedals can be made when the
vehicle is in R (Reverse) or while using the cruise
control.
The switch used to adjust
the pedals is located on
the instrument panel
below the climate control
system.
Press the arrow at the bottom of the switch to move the
pedals closer to your body. Press the arrow at the top of
the switch to move the pedals away from your body. Before you start driving, fully press the brake pedal to
confirm the adjustment is right for you. While driving,
make only small adjustments.
The vehicle may have a memory function which lets
pedal settings be saved and recalled. See
Memory
Seat, Mirrors, and Pedals
on page 2‑8for more
information.
Engine Coolant Heater
The engine heater can provide easier starting and
better fuel economy during engine warm-up in cold
weather conditions at or below −18°C (0°F). Vehicles
with an engine heater should be plugged in at least
four hours before starting. An internal thermostat
in the plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures
above −18°C (0°F).
If the vehicle has the DURAMAX
®Diesel engine, see
the DURAMAX®Diesel manual for more information.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. Thecord is secured to the Engine Compartment Fuse
Block with a clip. Carefully remove the wire tie
which bundles the electrical plug. Do not cut the
electrical cord.
3. Plug the cord into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.
4. Before starting the engine, be sure to unplug and store the cord as it was before to keep it away from
moving engine parts. If you do not, it could be
damaged. The length of time the heater should remain plugged in
depends on several factors. Ask a dealer in the area
where you will be parking the vehicle for the best advice
on this.
Active Fuel Management™
Vehicles with V8 engines may have Active Fuel
Management™. This system allows the engine to
operate on either all or half of its cylinders, depending
on the driving conditions.
When less power is required, such as cruising at a
constant vehicle speed, the system will operate in the
half cylinder mode, allowing the vehicle to achieve
better fuel economy. When greater power demands are
required, such as accelerating from a stop, passing,
or merging onto a freeway, the system will maintain
full-cylinder operation.
If the vehicle has an Active Fuel Management™
indicator, see
DIC Operation and Displays (With DIC
Buttons)
on page 4‑49or DIC Operation and Displays
(Without DIC Buttons)on page 4‑56for more
information on using this display.

Park Tilt Mirrors
If the vehicle has the memory package, the passenger
and/or driver mirror tilts to a preselected position when
the vehicle is in R (Reverse). This feature lets the driver
view the curb when parallel parking. The mirror(s) return
to the original position when the vehicle is shifted out of
R (Reverse), or the ignition is turned off or to
OFF/LOCK.
Turn this feature on or off through the Driver Information
Center (DIC). SeeDIC Vehicle Customization (With DIC
Buttons)
on page 4‑73for more information.
Outside Convex Mirror
{WARNING:
A convex mirror can make things, like other
vehicles, look farther away than they really are.
If you cut too sharply into the right lane, you could
hit a vehicle on the right. Check the inside mirror
or glance over your shoulder before changing
lanes.
The passenger side mirror is convex shaped. A convex
mirror's surface is curved so more can be seen from the
driver seat.
Outside Heated Mirrors
For vehicles with heated mirrors:
<(Rear Window Defogger): Press to heat the
mirrors. If the vehicle has a towing mirror, only the
upper glass of the mirror is heated. The lower convex
part of the towing mirror is not heated.
Depending on the vehicle's features, see “Rear Window
Defogger” under,Climate Control System (With Air
Conditioning)
on page 4‑18or Climate Control System
(With Heater Only)on page 4‑21or Dual Automatic
Climate Control Systemon page 4‑22for more

Climate Control System (With
Heater Only)
With this system the heating and ventilation can be
controlled.
A. Fan Control
B. Temperature Control
C. Air Delivery Mode Control
Temperature Control: Turn clockwise or
counterclockwise to increase or decrease the
temperature inside the vehicle.
9(Fan Control): Turn clockwise or counterclockwise
to increase or decrease the fan speed. Turn the knob all
the way counterclockwise to turn the front system off.
Air Delivery Mode Control: Turn clockwise or
counterclockwise to increase or decrease the
temperature inside the vehicle. The knob can be
positioned between two modes to select a combination
of those modes.
Select from the following:
H (Vent): Air is directed to the instrument panel outlets.
) (Bi-Level): Air is divided between the instrument
panel and floor outlets.
6 (Floor): Air is directed to the floor outlets, with some
air directed to the windshield, side window, and second
row floor outlets. In this mode, the system automatically
selects outside air.
- (Defog): This mode clears the windows of fog or
moisture. Air is directed to the windshield, floor outlets,
and side window vents.
0 (Defrost): This mode removes fog or frost from the
windshield more quickly. Air is directed to the
windshield and the side window vents, with some air
directed to the floor vents. The system automatically
forces outside air into the vehicle.
Do not drive the vehicle until all the windows are clear.

Sound System. Some of its features are explained later
in this section under, “Adjusting the Speakers
(Balance/Fade)”.
If the vehicle has a Rear Seat Entertainment (RSE)
system, it has a CD/DVD radio. See Rear Seat
Entertainment (RSE) System
on page 4‑132for more
information on the vehicle's RSE system.
The DVD player is the top slot on the radio faceplate.
The player is capable of reading the DTS programmed

Many service stations will not have an 85% ethanol fuel
(E85) pump available. The U.S. Department of Energy
has an alternative fuels website (www.eere.energy.gov/
afdc/infrastructure/locator.html) that can help you find
E85 fuel. Those stations that do have E85 should have
a label indicating ethanol content. Do not use the fuel if
the ethanol content is greater than 85%.
At a minimum, E85 should meet ASTM Specification
D 5798. By definition, this means that fuel labeled E85
will have an ethanol content between 70% and 85%.
Filling the fuel tank with fuel mixtures that do not meet
ASTM specifications can affect driveability and could
cause the malfunction indicator lamp to come on.To ensure quick starts in the wintertime, the E85 fuel
must be formulated properly for your climate according
to ASTM specification D 5798. If you have trouble
starting on E85, it could be because the E85 fuel is not
properly formulated for your climate. If this happens,
switching to gasoline or adding gasoline to the fuel tank
can improve starting. For good starting and heater
efficiency below 0°C (32°F), the fuel mix in the fuel tank
should contain no more than 70% ethanol. It is best not
to alternate repeatedly between gasoline and E85.
If you do switch fuels, it is recommended that you add
as much fuel as possible
—do not add less than
11 L (three gallons) when refueling. You should drive
the vehicle immediately after refueling for at least 11 km
(seven miles) to allow the vehicle to adapt to the
change in ethanol concentration.
E85 has less energy per gallon than gasoline, so you
will need to refill the fuel tank more often when using
E85 than when you are using gasoline. See Filling the
Tank on page 6‑11.
