2008 GMC CANYON brake

Shifting from Four-Wheel Low to
Two-Wheel High or Four-Wheel High
To shift from Four-Wheel Low to Two-Wheel High or
Four-Wheel High, your vehicle must be stopped
or moving less than 3 mph (5 km/h) with the
transmission in NEUTRAL (N) for an automatic
transmission or the clutch pedal pressed for a manual
transmission. The preferred method for shifting out of
four-wheel low is to have your vehicle moving 1 to 2 mph
(1.6 to 3.2 km/h).
Press and release the Four-Wheel High or Two-Wheel
High button. You must wait for the Four-Wheel High
or Two-Wheel High indicator light to stop ashing and
stay on before shifting the transmission into gear or
releasing the clutch pedal.
If the Four-Wheel High or Two-Wheel High button is
pressed when your vehicle is in gear and/or moving
faster than 3 mph (5km/h), the Four-Wheel High or Two
Wheel High indicator light will ash for 30 seconds but
not complete the shift.
Shifting to NEUTRAL
Use NEUTRAL when you plan to tow your vehicle. See
Recreational Vehicle Towing on page 4-38for towing
instructions. To shift the transfer case into NEUTRAL do
the following:
1. Set the parking brake.
2. Start the vehicle.
3. Press the regular brake pedal and shift the
transmission in NEUTRAL (N), or press in the clutch
for vehicles with a manual transmission.
4. Shift the transfer case to Two-Wheel High.
5. Press and hold the Two-Wheel High and
Four-Wheel Low buttons at the same time for
10 seconds. The NEUTRAL (N) light will come on
when the transfer case shift to NEUTRAL (N)
is complete.
6. Press and hold the regular brake pedal and shift
the transmission to REVERSE (R) for one second,
then shift the transmission to DRIVE (D) for one
second, or FIRST (1) for vehicles with manual
transmissions, and let out the clutch to insure the
transfer case is in NEUTRAL. If the vehicle is not in
NEUTRAL, repeat this procedure starting at Step 3.

above the parking brake pedal, with the parking brake
symbol, directly rearward to release the parking brake.If the ignition is on when the parking brake is released,
the brake system warning light will go off.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill, see
Towing a Trailer on page 4-44.

Shifting Into PARK (P)
(Automatic Transmission)
{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. If you are
pulling a trailer, seeTowing a Trailer on
page 4-44.
1. Hold the brake pedal down with your right foot and
set the parking brake.
SeeParking Brake on page 2-32for more
information.
{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, two-wheel high (2H) or four-wheel
high (4H) or four-wheel low (4L) — not in
NEUTRAL.
2. Move the shift lever into PARK (P) by pulling the
lever toward you and moving it up as far
as it will go.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the key, your vehicle
is in PARK (P).

Leaving Your Vehicle With the Engine
Running (Automatic Transmission)
{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.
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.
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 pulling it
toward you. If you can, it means that the shift lever was
not fully locked into PARK (P).
Torque Lock (Automatic Transmission)
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)
(Automatic Transmission) on page 2-34.
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).
2-35

Shifting Out of PARK (P)
(Automatic Transmission)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when
the ignition is RUN. SeeAutomatic Transmission
Operation on page 2-23.
The shift lock control system is designed to do the
following:
Prevent the ignition key from being removed unless
the shift lever is in PARK (P).
Prevent movement of the shift lever out of PARK
(P), unless the ignition is in ON/RUN and the
regular brake pedal is applied.
The shift lock control system is always functional
except in the case of a dead battery or low voltage
(less than 9 V) battery.If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 5-42for more
information.
To shift out of PARK (P) use the following:
1. Apply the brake pedal.
2. Move the shift lever to the desired position.
If you still are unable to shift out of PARK (P):
1. Ease the pressure on the shift lever.
2. While holding down the brake pedal, push the shift
lever all the way into PARK (P)
3. Move the shift lever to the desired position.
If you are still having a problem shifting, then have your
vehicle serviced soon.
2-36

Parking Your Vehicle
(Manual Transmission)
Your vehicle has a manual transmission. Before
you get out of your vehicle, move the shift lever into
REVERSE (R), and rmly apply the parking brake.
Once the shift lever has been placed into REVERSE (R)
with the clutch pedal pressed in, turn the ignition key
to LOCK, remove the key and release the clutch.
If you are parking on a hill, or if your vehicle is pulling a
trailer, seeTowing a Trailer on page 4-44.
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.
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:
The 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 the exhaust system has
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.
2-37

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.
SeeWinter Driving on page 4-27.
{CAUTION:
It can be dangerous to get out of your vehicle
if the automatic transmission 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 it is on fairly level
ground, always set the parking brake and
move the automatic transmission shift lever to
PARK (P), or the manual transmission shift
lever to NEUTRAL.
