lock GMC CANYON 2010 Service Manual

START (D):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
20 minutes after the engine is turned off:
•Audio System
•Wipers
•Power Windows
These features work when the key is in ON/RUN or
ACC/ACCESSORY. Once the key is turned from
ON/RUN to LOCK/OFF, power to these features
continue to work for up to 20 minutes or until a door
is opened.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to P (Park) or N (Neutral).
The engine will not start in any other position.
To restart the vehicle when it is already moving,
use N (Neutral) only.
Notice:Do not try to shift to P (Park) if the vehicle
is moving. If you do, you could damage the
transmission. Shift to P (Park) only when the vehicle
is stopped.
Manual Transmission
The shift lever should be in N (Neutral) and the parking
brake engaged. Hold the clutch pedal down to the
floor and start the engine. The vehicle will not start if the
clutch pedal is not all the way down.

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as the
engine warms. Do not race the engine immediately
after starting it. Operate the engine and
transmission gently to allow the oil to warm up and
lubricate all moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects components. If the ignition key
is turned to the START position, and then
released when the engine begins cranking, the
engine will continue cranking for a few seconds or
until the vehicle starts. If the engine does not
start and the key is held in START for many
seconds, cranking will be stopped after 15 seconds
to prevent cranking motor damage. To prevent
gear damage, this system also prevents cranking if
the engine is already running. Engine cranking
can be stopped by turning the ignition switch
to ACC/ACCESSORY or LOCK/OFF.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or
−18°C), it could be flooded with too much gasoline.
Push the accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool. When the engine starts,
let go of the key and accelerator. If the vehicle starts
briefly but then stops again, repeat the procedure.
This clears the extra gasoline from the engine.
Do not race the engine immediately after starting it.
Operate the engine and transmission gently until
the oil warms up and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.

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.
3-20

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

3 (Third), 4 (Fourth) and 5 (Fifth):Shift into 3 (Third),
4 (Fourth) and 5 (Fifth) the same way you do for
2 (Second). Slowly let up on the clutch pedal as you
press the accelerator pedal.
To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press the
clutch pedal and the brake pedal, and shift to Neutral.
Neutral:Use this position when you start or idle the
engine.
R (Reverse):To back up, press the clutch pedal.
After the vehicle stops, shift into R (Reverse). Slowly let
up on the clutch pedal as you press the accelerator
pedal. If it is hard to shift, let the shift lever return
to Neutral and release the clutch pedal. Then press
the clutch again and shift into R (Reverse). Do not
attempt to shift into 5 (Fifth) prior to shifting into
R (Reverse). The transmission has a lock out feature
which prevents a 5 (Fifth) gear to R (Reverse) gear shift.
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.
Use R (Reverse), along with the parking brake, for
parking the vehicle.Up-Shift Light
This light will show you
when to shift to the next
higher gear for best
fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road and traffic conditions permit.
For the best fuel economy, accelerate slowly and shift
when the light comes on.
While you accelerate, it is normal for the light to go on
and off if you quickly change the position of the
accelerator. Ignore the shift light when you downshift.
If the vehicle has four-wheel drive and has a manual
transmission, disregard the shift light when the transfer
case is in four-wheel low.
3-24

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.
3-27

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 N (Neutral) light will come on when
the transfer case shift to N (Neutral) is complete.
6. Press and hold the regular brake pedal and shift
the transmission to R (Reverse) for one second,
then shift the transmission to D (Drive) for
one second, or 1 (First) for vehicles with manual
transmissions, and let out the clutch to insure
the transfer case is in N (Neutral). If the transfer
case is not in N (Neutral), repeat this procedure
starting at Step 3.
7. Turn the engine off by turning the key to
ACC/ACCESSORY.
8. Place the transmission shift lever in P (Park),
or 1 (First) for vehicles that have a manual
transmission.
9. Turn the ignition to LOCK/OFF.Shifting Out of Neutral
After towing the vehicle, you will have to shift out of
N (Neutral) in order to drive. To shift out of N (Neutral),
do the following:
1. Set the parking brake and apply the regular brake
pedal.
2. Start a vehicle with an automatic transmission in
P (Park). Use 1 (First) for vehicles with a manual
transmission.
3. Shift the transmission to N (Neutral), or press the
clutch pedal for vehicles with a manual
transmission.
4. Press the button for the desired transfer case shift
position (Two-Wheel High, Four-Wheel High, or
Four-Wheel Low).
5. After the transfer case has shifted out of N (Neutral),
the indicator light will go out.
6. Release the parking brake.
7. Shift the transmission to the desired position.
3-29

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.
