GMC ENVOY 2009 Owner's Manual

Leaving the Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) with the
parking brake rmly set.
If you have four-wheel drive, the vehicle will be
free to roll – even if your lever is in P (Park) – if
the transfer case is in Neutral. So be sure the
transfer case is in a drive gear – not Neutral. See
Four-Wheel Drive on page 2-28.
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 the
vehicle with the engine running unless you
have to.If you have to leave the vehicle with the engine running,
be sure the vehicle is in P (Park) and the parking
brake is rmly set before you leave it. After you have
moved the shift lever into P (Park), hold the regular
brake pedal down. Then, see if you can move the shift
lever away from P (Park) without rst pressing the
button on the console shift lever. If you can, it means
that the shift lever was not fully locked into P (Park).
Torque Lock
If you are parking on a hill and you do not shift your
transmission into P (Park) 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 P (Park). This is called “torque lock.” To
prevent torque lock, set the parking brake and then
shift into P (Park) properly before you leave the driver
seat. To nd out how, seeShifting Into Park on
page 2-34.
When you are ready to drive, move the shift lever out of
P (Park) 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 P (Park).
2-35

Shifting Out of Park
The vehicle has an electronic shift lock release system.
The shift lock release is designed to:
Prevent ignition key removal unless the shift lever
is in P (Park) with the shift lever button fully
released, and
Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN and the regular
brake pedal is applied.
The shift lock release is always functional except in the
case of an uncharged or low voltage (less than 9 volt)
battery.
If the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
SeeJump Starting on page 5-39for more information.
To shift out of P (Park) use the following:
1. Apply the brake pedal.
2. Press the shift lever button.
3. Move the shift lever to the desired position.If you still are unable to shift out of P (Park):
1. Fully release the shift lever button.
2. Hold the brake pedal down and press the shift lever
button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from P (Park),
consult your dealer/retailer or a professional towing
service.

Things that can burn could touch hot exhaust
parts under the vehicle and ignite. Do not park
over papers, leaves, dry grass, or other things that
can burn.
2-36

Engine Exhaust
{CAUTION:
Engine exhaust contains Carbon Monoxide (CO)
which cannot be seen or smelled. Exposure to CO
can cause unconsciousness and even death.
Exhaust may enter the vehicle if:
The vehicle idles in areas with poor ventilation
(parking garages, tunnels, deep snow that
may block underbody airow or tail pipes).
The exhaust smells or sounds strange or
different.
The exhaust system leaks due to corrosion or
damage.
CAUTION: (Continued)
CAUTION: (Continued)

The vehicle’s exhaust system has been
modied, damaged or improperly repaired.
There are holes or openings in the vehicle
body from damage or after-market
modications that are not completely sealed.
If unusual fumes are detected or if it is suspected
that exhaust is coming into the vehicle:
Drive it only with the windows
completely down.
Have the vehicle repaired immediately.
Never park the vehicle with the engine running in
an enclosed area such as a garage or a building
that has no fresh air ventilation.
2-37

Running the Vehicle 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 a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information, see
Engine Exhaust on page 2-37.
{CAUTION:
It can be dangerous to get out of the vehicle if the
automatic transmission shift lever is not fully in
P (Park) with the parking brake rmly set. The
CAUTION: (Continued)
CAUTION: (Continued)
vehicle can roll. Do not leave the 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 the vehicle will not move, even when you are
on fairly level ground, always set the parking
brake and move the shift lever to P (Park).
{CAUTION:
If the vehicle has four-wheel drive, it will be free to
roll — even if the shift lever is in P (Park) — if the
transfer case is in N (Neutral). So be sure the
transfer case is in a drive gear — not in N (Neutral).
SeeFour-Wheel Drive on page 2-28.
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park on page 2-34.
