2010 GMC CANYON Owner's Manual

4n(Four-Wheel Low):This setting also engages the
front axle to give you extra traction. It sends the maximum
power to all four wheels. You might choose four-wheel
low if you were driving off-road in sand, mud, or deep
snow and while climbing or descending steep hills.
Shifting into Four-Wheel Low will turn Traction Control
and StabiliTrak
®off. SeeTraction Control System (TCS)
on page 5-8andStabiliTrak®System on page 5-6for
more information.
Indicator lights in the buttons show you which setting you
are in. The indicator lights will come on briefly when you
turn on the ignition and one will stay on the selected
setting. If the lights do not come on, you should take the
vehicle in for service. An indicator light will flash while
shifting. It will stay on when the shift is completed.
If the transfer case does not shift, it will return to the last
chosen setting.
Shifting from Two-Wheel High to
Four-Wheel High
Press and release the Four-Wheel High button.
This can be done at any speed, and the front axle will
lock automatically.
Shifting from Four-Wheel High to
Two-Wheel High
Press and release the Two-Wheel High button.
This can be done at any speed, and the front axle will
unlock automatically.
It is normal to hear and feel the vehicle’s transfer
case shift into Four-Wheel High. If you shift with the
vehicle stopped, the indicator light may still flash slowly.
It may be necessary to shift the transmission
momentarily into R (Reverse) and D (Drive), for an
automatic transmission, or R (Reverse) and 1 (First) for
a manual transmission to have the light stop flashing.

Parking Brake
The parking brake pedal is
located to the left of the
brake pedal, near the
driver door.
To set the parking brake, hold the brake pedal down,
then push the parking brake pedal down to its
fully-applied position.
A chime will activate and the brake warning light,
located on the instrument panel, will flash when the
parking brake is applied and the vehicle is moving at
least 3 mph (5 km/h) for at least three seconds.
The chime will deactivate and the light will turn off
when the parking brake is set and the vehicle is moving
below 3 mph (5 km/h). SeeBrake System Warning
Light on page 4-25.To release the parking brake, hold the regular brake
pedal down. Pull the bottom edge of the lever, located
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,
seeTowing a Trailer on page 5-48.

Shifting Into Park
(Automatic Transmission)
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll. 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, use the steps that follow.
If you are pulling a trailer, seeTowing a Trailer on
page 5-48.
1. Hold the brake pedal down with your right foot and
set the parking brake.
SeeParking Brake on page 3-30for more
information.
{WARNING:
If you have four-wheel drive, the vehicle will be free
to roll — even if the shift lever is in P (Park) — if the
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 P (Park) by pulling the
lever toward you and moving it up as far as it
will go.
3. Turn the ignition key to LOCK/OFF.
4. Remove the key and take it with you. If you can
leave the vehicle with the key, the vehicle is in
P (Park).
3-31

Leaving the Vehicle With the Engine
Running (Automatic Transmission)
{WARNING:
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 firmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch fire. You or others could be
injured. Do not leave the vehicle with the engine
running.
If you have to leave the vehicle with the engine running,
be sure the vehicle is in P (Park) and the parking
brake is firmly 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 first pulling it toward
you. If you can, the shift lever was not fully locked
into P (Park).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift the
transmission into P (Park) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transmission. You may find 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 find out how, seeShifting Into Park
(Automatic Transmission) on page 3-31.
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).
Shifting Out of Park
(Automatic Transmission)
The vehicle has an automatic transmission shift lock
control system. You have to fully apply the brake pedal
before you can shift from P (Park) when the ignition
is ON/RUN. SeeAutomatic Transmission Operation on
page 3-21.
3-32

The shift lock control system is designed to do the
following:
•Prevent the ignition key from being removed unless
the shift lever is in P (Park).
•Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN and the 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 the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
SeeJump Starting on page 6-43for more information.
To shift out of P (Park) 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 P (Park):
1. Ease the pressure on the shift lever.
2. While holding down the brake pedal, push the shift
lever all the way into P (Park)
3. Move the shift lever to the desired position.
If you are still having a problem shifting, then have the
vehicle serviced.
Parking the Vehicle
(Manual Transmission)
If the vehicle has a manual transmission, before you get
out of the vehicle, move the shift lever into R (Reverse),
and firmly apply the parking brake. Once the shift
lever has been placed into R (Reverse) with the clutch
pedal pressed in, turn the ignition key to LOCK/OFF,
remove the key and release the clutch.
If you are parking on a hill, or if the vehicle is pulling a
trailer, seeTowing a Trailer on page 5-48.
Parking Over Things That Burn
{WARNING:
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.
3-33

Engine Exhaust
{WARNING:
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 airflow or tail pipes).
•The exhaust smells or sounds strange or
different.
•The exhaust system leaks due to corrosion
or damage.
•The vehicle’s exhaust system has been
modified, damaged or improperly repaired.
•There are holes or openings in the vehicle
body from damage or after-market
modifications that are not completely sealed.
WARNING: (Continued)
WARNING: (Continued)
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.
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.
{WARNING:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
