2010 GMC CANYON warning

Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicles
with an engine coolant heater should be plugged
in at least four hours before starting. An internal
thermostat in the plug-end of the cord may exist
which will prevent engine coolant heater operation at
temperatures above 0° F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the engine compartment
behind the underhood fuse block on the driver side
of the vehicle.
3. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
You could be seriously injured. Plug the cord
into a properly grounded three-prong 110-volt
AC outlet. If the cord will not reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord to prevent damage.
The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in
the area where you will be parking the vehicle for the
best advice on this.

Automatic Transmission Operation
The vehicle has a shift lever on the steering column.
It features an electronic shift position indicator within the
instrument cluster. This display is powered anytime
the shift lever is capable of being moved out of P (Park).
This means that if the ignition is turned off, but not in
LOCK/OFF, there will be a small current drain on
the battery which could discharge the battery over a
period of time. If you need to leave the key in the ignition
but not in LOCK/OFF for an extended period, it is
recommended that you disconnect the battery cable
from the battery to prevent discharging the battery.
There are several different positions for the shift lever.
P (Park):This position locks the rear wheels. It is
the best position to use when you start the engine
because the vehicle cannot move easily.
{WARNING:
It is 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.
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). SeeShifting Into
Park (Automatic Transmission) on page 3-31.
If you are pulling a trailer, seeTowing a Trailer on
page 5-48.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You must fully
apply the brake pedal before you can shift from P (Park)
when the ignition key is in ON/RUN. If you cannot
shift out of P (Park), ease pressure on the shift lever by
pushing the shift lever all the way into P (Park) as
you maintain brake application. Then move the shift
lever into another gear. SeeShifting Out of Park
(Automatic Transmission) on page 3-32.
3-21

R (Reverse):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock your vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission, see
If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 5-31.
N (Neutral):In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is are already moving, use N (Neutral) only.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
D (Drive):This position is for normal driving. It provides
the best fuel economy. If you need more power for
passing, and you are:
•Going less than about 35 mph (55 km/h), push the
accelerator pedal about halfway down.
•Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transmission will shift down to the next gear and
the vehicle will have more power.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 5-12.
3-22

Shift Speeds
{WARNING:
If you skip a gear when you downshift, you could
lose control of the vehicle. You could injure
yourself or others. Do not shift down more than
one gear at a time when you downshift.
Four-Wheel Drive
If the vehicle has four-wheel drive, you can send the
engine’s driving power to all four wheels for extra
traction. To get the best performance out of four-wheel
drive, you must be familiar with its operation. Read
this section before using four-wheel drive. You should
use two-wheel-drive high for most normal driving
conditions.
Notice:Driving on clean, dry pavement in
four-wheel drive for an extended period of time can
cause premature wear on the vehicle’s powertrain.
Do not drive on clean, dry pavement in Four-Wheel
Drive for extended periods of time.Notice:If the vehicle has four-wheel drive and the
different size spare tire is installed on the vehicle,
do not drive in four-wheel drive until you can have
your at tire repaired and/or replaced. You could
damage the vehicle, and the repair costs would not
be covered by your warranty. Never use four-wheel
drive when the different size spare tire is installed on
the vehicle.
Notice:If the vehicle has four-wheel drive and the
compact spare tire is installed on the vehicle, do not
drive in four-wheel drive until you can have the at
tire repaired and/or replaced. You could damage the
vehicle, and the repair costs would not be covered by
your warranty. Never use four-wheel drive when the
compact spare tire is installed on the vehicle.
The transfer case buttons are located to the right of the
steering wheel on the instrument panel.

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.
