2005 GMC ENVOY XUV Owner's Manual

Shifting Into Park (P)
{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.
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,
use the steps that follow. With 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. Always put
the shift lever fully in PARK (P) with the parking
brake rmly set. If you are pulling a trailer,
seeTowing a Trailer on page 4-55.To shift into PARK (P), do the following:
1. Hold the brake pedal down with your foot and set
the parking brake.
2. Move the shift lever into PARK (P) by pressing the
button on the side of the shift lever and pushing the
lever all the way toward the front of the vehicle.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. You know
your vehicle is in PARK (P) if the key can be
removed from the ignition.

Leaving Your Vehicle With the
Engine Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
If you have four-wheel drive, your vehicle
will be free to roll — even if your lever is in
PARK (P) — if your transfer case is in
NEUTRAL. So be sure the transfer case is in a
drive gear — not NEUTRAL. SeeFour-Wheel
Drive on page 2-32.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running unless
you have to.If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and
your parking brake is rmly set before you leave it.
After you have moved the shift lever into PARK (P),
hold the regular brake pedal down. Then, see if you can
move the shift lever away from PARK (P) without rst
pressing the button on the console shift lever. If you can,
it means that the shift lever was not fully locked into
PARK (P).
Torque Lock
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. You may nd it difficult to pull the
shift lever out of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave the
driver’s seat. To nd out how, seeShifting Into Park (P)
on page 2-37.
2-38

When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission,
so you can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply the regular
brakes before you can shift from PARK (P) when the
ignition is in RUN. SeeAutomatic Transmission
Operation on page 2-29.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Do not
park over papers, leaves, dry grass or other
things that can burn.
2-39

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.

Mirrors
Manual Rearview Mirror
While sitting in a comfortable driving position, adjust the
rearview mirror so you can see clearly behind your
vehicle. Grip the mirror in the center to move it up or
down and side to side. The day/night control, located at
the bottom of the mirror, adjusts the mirror to reduce
headlamp glare from behind during evening or dark
conditions. Turn the control clockwise for night
use; return it to the center for daytime use.
Manual Rearview Mirror with
OnStar
®
The vehicle may have a rearview mirror with the
OnStar®system.
Control buttons for the OnStar
®system are at the
bottom of the mirror. See your GM dealer for more
information on the OnStar
®system and how to
subscribe to OnStar®. Also, seeOnStar®System on
page 2-52for more information about the services
OnStar
®provides.
Mirror Operation

Compass Display
O
(On/Off):Press this button to turn the compass on
or off. The compass display, can show a maximum
of two characters. For example, NE is displayed
for north-east.
When the ignition and the compass/temperature feature
are on, character boxes will appear for about two
seconds. After two seconds, the mirror will display the
direction the vehicle is facing.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two seconds, the display
does not show a compass direction, (N for North,
for example), there may be a strong magnetic eld
interfering with the compass. Such interference may be
caused by a magnetic antenna mount, magnetic
note pad holder, or a similar magnetic item. If the
letter C should ever appear in the compass window,
the compass may need calibration.Press and hold the on/off button for nine seconds to
activate the compass calibration mode. CAL will
be displayed in the compass window on the mirror.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display shows
a direction.
Compass Variance
Compass variance is the difference between
earth’s magnetic north and true geographic north.
The mirror is set to zone eight upon leaving the
factory. It will be necessary to adjust the compass to
compensate for compass variance if you live outside
zone eight. Under certain conditions, such as during a
long-distance, cross-country trip, it will be necessary
to adjust for compass variance. If not adjusted to
account for compass variance, the compass could
give false readings.
2-43

To adjust for compass variance do the following:
1. Find the current location and variance zone number
on the following zone map.
2. Press and hold the on/off button until a zone
number appears in the display.
3. Once a zone number appears in the display, press
the on/off button quickly until the correct zone
number appears in the display. If C appears in
the compass window, the compass may need
calibration. See “Compass Calibration”
explained previously.Manual Rearview Mirror with
