2004 GMC CANYON ignition

4n(4LO):This setting also engages your front axle to
give you extra traction. It sends the maximum power
to all four wheels. You might choose 4LO if you
were driving off-road in sand, mud or deep snow and
climbing or descending steep hills.
Indicator lights in the buttons show you which setting
you are in. The indicator lights will come on briey when
you turn on the ignition and one will stay on. If the
lights do not come on, you should take your vehicle in
for service. An indicator light will ash while shifting.
It will remain illuminated when the shift is completed.
If for some reason the transfer case cannot make
a requested shift, it will return to the last chosen setting.
Shifting from 2HI to 4HI
Press and release the 4HI button. This can be done at
any speed, and the front axle will lock automatically.
Shifting from 4HI to 2HI
Press and release the 2HI button. This can be done at
any speed, and the front axle will unlock automatically.
Shifting from 2HI or 4HI to 4LO
To shift from 2HI or 4HI to 4LO, the vehicle must be
stopped or moving less than 1.2 mph (2 km/h) with the
transmission in NEUTRAL (N) in vehicles equipped
with an automatic transmission or the clutch pedal
engaged in vehicles equipped with a manual
transmission. The preferred method for shifting into
4LO is to have your vehicle moving 1.2 mph (2 km/h).
Press and release the 4LO button. You must wait for
the 4LO indicator light to stop ashing and remain
illuminated before shifting your transmission into gear or
releasing the clutch pedal.
If the 4LO button is pressed when your vehicle is in
gear and/or moving, the 4LO indicator light will ash for
30 seconds and not complete the shift.
On automatic transmission equipped vehicles, if your
transfer case does not shift into 4LO, your transmission
indicator switch may require adjustment. With your
transmission in NEUTRAL (N), press and release the
4LO button. While the 4LO indicator light is ashing, shift
your transmission into PARK (P). Press 4LO again.
Wait until the 4LO indicator light remains illuminated
before shifting your transmission into gear. Press
the 4LO button again to complete the shift. This will get
you into 4LO, but you should take your vehicle in for
service to restore normal operation.

Parking Brake
The parking brake pedal is
located to the left of the
regular brake pedal,
near the driver’s door.
To set the parking brake, hold the regular brake pedal
down with your right foot. Push down the parking
brake pedal with your left foot.
A chime will activate and the warning light will ash
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 3-28.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, 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. Verify 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 4-60.
2-29

Move the lever 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
{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’ve 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 wasn’t fully locked into PARK (P).
2-31

Torque Lock
If you are parking on a hill and you don’t 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 2-30.
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).
Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift lock
control system which locks the shift lever in PARK
(P) when the ignition is in the LOCK position. In addition,
you have to fully apply the regular brakes before you
can shift from PARK (P) when the ignition is in ON.
SeeAutomatic Transmission Operation on page 2-21.
If you cannot shift out of PARK (P), ease pressure
on the shift lever by pushing the shift lever all the way
into PARK (P) as you maintain brake application.
Then, press the shift lever button and move the shift
lever into the gear you want.
If you ever hold the brake pedal down but still cannot
shift out of PARK (P), try this:
1. Turn the key to ACC (Accessory).
(There is no shift interlock in this key position.)
2. Apply and hold the brake until the end of Step 4.
3. Shift the transmission to NEUTRAL (N).
4. Start the vehicle and then shift to the gear you want.
5. Have the system xed as soon as you can.
2-32

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, you can 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 4-60.
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.

Automatic Dimming Rearview Mirror
with Compass and Temperature
Display
Your vehicle may have an automatic dimming rearview
mirror with a compass, temperature display, and
map lamps.
Mirror Operation
The mirror automatically changes to reduce glare from
headlamps behind you. A time delay feature prevents
rapid changing from the day to night positions while
driving under lights and through traffic.
P(On/Off):The automatic dimming feature is
automatically activated when the vehicle is started.
The automatic dimming feature is turned on or off by
pressing this button located on the lower part of
the mirror. Press and hold the button for up to three
seconds to turn this feature on or off.
T(Indicator Light):This light will turn on when the
automatic dimming feature is active.
Map Lamps
The mirror has map lamps located at the bottom of the
mirror. To manually turn the lamps on or off, press
the button next to each lamp.
Compass Operation
The mirror has an eight-point compass display in
the upper right corner of the mirror face. When on,
the compass automatically calibrates as the vehicle is
driven.
When the ignition and the compass feature are on,
the compass will show two character boxes for
approximately two seconds. After two seconds,
the mirror will display the current compass heading.
For example, NE is displayed for north-east.
Compass Calibration
If after two seconds the display does not show a
compass heading, there may be a strong magnetic eld
interfering with the compass. Such interference may
be caused by a magnetic antenna mount, note
pad holder or similar object. If the letter C appears in
the compass window, the compass needs calibration.
The mirror compass can be calibrated by driving
the vehicle in circles at 5 mph (8 km/h) or less until the
display reads a direction.
The compass can be placed in calibration mode by
pressing and holding the on/off button until a C appears
on the compass display.
2-37

Move the cruise switch from on to resume/
accelerate. Hold it there until you get up to the
speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch briey to resume/accelerate.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control

Press and hold the set button until you reach the
lower speed you want, then release it.
To slow down in very small amounts, briey press
the set button. Each time you do this, you’ll go
about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may want to
step on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control.
Many drivers nd this to be too much trouble and don’t
use cruise control on steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
Step lightly on the brake pedal
Move the cruise control switch to off
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.

Automatic Headlamp System
Your vehicle may be equipped with this feature.
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights. The radio lights may also
be dim.
Your vehicle may have a light sensor located on the top
of the instrument panel. Be sure it is not covered, or
the system will be on whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp system so
that driving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system will only be affected when the
light sensor sees a change in lighting lasting longer
than the delay.If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave the garage, it will take approximately several
seconds for the automatic headlamp system to change
to DRL if it is light outside. During that delay, your
instrument panel cluster may not be as bright as usual.
Make sure your instrument panel brightness control
is in the full bright position. See “Instrument Panel
Brightness” underInterior Lamps on page 3-15.
Lamps On Reminder
If a door is open, a reminder chime will sound when
your headlamps or parking lamps are manually turned
on and your key is out of the ignition. To turn off
the chime, turn the headlamp switch to off and then
back on. In the automatic mode, the headlamps turn off
once the ignition is in LOCK.
