2005 GMC ENVOY XUV engine

Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you cannot see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:
Your exhaust system sounds strange
or different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a collision.
Your vehicle was damaged when driving
over high points on the road or over
road debris.
Repairs were not done correctly.
Your vehicle or exhaust system had been
modied improperly.
If you ever suspect exhaust is coming into
your vehicle:
Drive it only with all the windows down to
blow out any CO; and
Have your vehicle xed immediately.
Running Your Engine While You
Are 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 2-40.
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.
SeeWinter Driving on page 4-38.

{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).
{CAUTION:
If you have four-wheel drive, your vehicle will
be free to roll — even if your shift lever is in
PARK (P) — if your transfer case is in
NEUTRAL. So be sure the transfer case is in a
drive gear — not in NEUTRAL. SeeFour-Wheel
Drive on page 2-32.
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park (P) on page 2-37.
If you are pulling a trailer, seeTowing a Trailer on
page 4-55.

Programming the HomeLink®
Transmitter
Do not use the HomeLink®Transmitter with any garage
door opener that does not have the “stop and reverse”
feature. This includes any garage door opener model
manufactured before April 1, 1982. If you have a newer
garage door opener with rolling codes, please be
sure to follow Steps 6 through 8 to complete the
programming of your HomeLink
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of the
steps involved, it may be helpful to have another person
available to assist you in programming the transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
®programming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
®buttons should be erased
for security purposes. Refer to “Erasing HomeLink®
Buttons” or, for assistance, contact HomeLink®on the
Internet at: www.homelink.com or by calling
1-800-355-3515.Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Programming HomeLink®
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
®buttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
®
buttons while keeping the indicator light in view.

To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs about half of the air
to the instrument panel outlets; then directs most of
the remaining air to the oor outlets. A little air is
directed toward the windshield and the side window
outlets. Cooler air is directed to the upper vents
and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with a little air directed to the windshield
and the side window outlets. The recirculation button
cannot be selected while in oor mode.
h(Recirculation):Recirculation mode is used to
recirculate the air inside of your vehicle. When this
button is pressed, an indicator light in the button
will come on to let you know that it is active. Use this
mode to help prevent outside odors and/or dust
from entering your vehicle or to help cool the air inside
of your vehicle more quickly. The air conditioning
compressor will also come on when this mode is
activated. While in recirculation mode, the windows
may fog when the weather is cold and damp. To clear
the fog, select either the defog or defrost mode and
increase fan speed.Driver’s Side Temperature Knob:The lever on the
left side of the climate control panel is used to raise or
lower the temperature on the driver’s side of the
vehicle. Slide the lever up or down to adjust the

Dual Automatic Climate Control
System
Your vehicle may have the dual automatic climate
control system. With this system you can control the
heating, cooling and ventilation for your vehicle.
When your vehicle is rst started and the climate control
system is on, or if the climate control system has
been turned on, the display will show the driver’s
temperature setting for ve seconds. Then it will show
the outside temperature.
Outside Air Temperature Display
A new outside temperature reading will be displayed if
the vehicle has been off for more than three hours. If the
vehicle has been off for less than three hours, the old
temperature reading may be displayed because
underhood heat is affecting the true outside temperature.
Since underhood heat can also affect the outside
temperature while the engine is running, it may take
several minutes of driving before the display updates to
the actual outside temperature.
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. Press the AUTO button,
the mode button, the fan arrows, or either temperature
knob to turn the system on.
C(Mode):Press this button to manually select the
air delivery mode to the oor, instrument panel, or
windshield outlets. The system will stay in the selected
mode until the mode button is pressed again or the
AUTO button is pressed.

Manual Operation
To change the current setting, select one of the
following:
w9x(Fan):This button allows you to manually
adjust the fan speed. Press the up arrow to increase
fan speed and the down arrow to decrease fan speed.
The display will change to show you the selected
fan speed and the driver’s side temperature setting
for ve seconds.
C(Mode):Press this button to manually change the
direction of the airow in your vehicle. Keep pressing the
button until the desired mode appears on the display.
The display will change to show you the selected
air delivery mode and the driver’s temperature setting
for ve seconds.
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, then directs
the remaining air to the oor outlets. A little air is
directed toward the windshield and the side window
outlets. Cooler air is directed to the upper outlets and
warmer air to the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets. Some air also comes out of the defroster
and side window outlets. The recirculation button cannot
be selected in oor mode.
h(Recirculation):Press this button to turn
recirculation mode on or off. When this button is
pressed, an indicator light in the button will also come
on to let you know that it is activated. Recirculation
mode is used to recirculate the air inside of your vehicle.
Use this mode to help prevent outside odors and/or
dust from entering your vehicle or to help cool the air
inside of your vehicle more quickly. Recirculation
mode can be used with vent and bi-level modes, but it
cannot be used with oor, defog or defrost modes.
See “Defogging and Defrosting” later in this section.
You may also notice that the air conditioning compressor
will run while in recirculation mode. This is normal
and will help to prevent fogging.
If the weather is cold and damp, the system may cause
the windows to fog while using recirculation mode. If the
windows do start to fog, select defog or defrost mode.
Recirculation mode, if selected, will be cleared when the
engine is turned off.
3-25

#A/C (Air Conditioning):Press this button to
manually turn the air conditioning system on or off.
When the system is on, the system will automatically
begin to cool and dehumidify the air inside of your
vehicle. The air conditioning symbol will appear on the
display when the air conditioning is on and will turn
off when the air conditioning is off.
If you select turn the air conditioning off while in front
defrost or defog mode, the air conditioning symbol
will turn off, however, the A/C compressor will remain
on to help de-humidify the air inside the vehicle. If one of
the other modes is selected the compressor will then
turn the A/C off until it is selected again or the
AUTO button is pressed.
You may notice a slight change in engine performance
when the air conditioning compressor shuts off and
turns on again. This is normal.Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. You can use either defog or front defrost
to clear fog or frost from your windshield.
-(Defog):Use this setting to clear the windows of
fog or moisture. This setting will deliver air to the
oor and windshield outlets.
0(Defrost):Press the front defrost button to clear
the windshield and side windows of frost or fog quickly.
The system will automatically control the fan speed if
you select defrost from AUTO mode. If the outside
temperature is 40°F (4°C) or warmer, your air
conditioning compressor will automatically run to help
dehumidify the air and dry the windshield. Do not
drive the vehicle until all the windows are clear.
