2004 GMC Canyon Owner ManualM

{CAUTION:
If the air bag readiness light ever comes on
when you have turned off the air bag, it means
that something may be wrong with the air bag
system. The right front passenger’s frontal air
bag could inate even though the switch is off.
If this ever happens, do not let anyone whom
the national government has identied as a
member of a passenger air bag risk group sit
in the right front passenger’s position (for
example, do not secure a rear-facing child
restraint in your vehicle) until you have your
vehicle serviced. SeeAir Bag Off Switch on
page 1-70.1. Your vehicle has a right front passenger’s frontal air
bag. SeeAir Bag Off Switch on page 1-70. If your
child restraint is forward-facing, always move the
seat as far back as it will go before securing it in this
seat. SeeManual Seats on page 1-3orPower Seats
on page 1-4. Never use a rear-facing child restraint in
this seat unless the air bag is off.
2. Find the LATCH anchorages in the passenger seat.
SeeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-46.
3. Put the child restraint on the seat.
4. Attach and tighten the LATCH attachments on the
child restraint to the LATCH anchorages in the
vehicle. The child restraint instructions will show
you how.

page 1-70.If your child restraint is equipped with the LATCH
system, seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-46. SeeTop Strap
on page 1-42if the child restraint has one.
If your child restraint does not have the LATCH system,
you will be using the lap-shoulder belt to secure the
child restraint in this position. Be sure to follow the
instructions that came with the child restraint. Secure
the child in the child restraint when and as the
instructions say.
1. Your vehicle has a right front passenger’s frontal
air bag. SeeAir Bag Off Switch on page 1-70.
If your child restraint is forward-facing, always move
the seat as far back as it will go before securing
it in this seat. SeeManual Seats on page 1-3
orPower Seats on page 1-4.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.
1-55

In many crashes severe enough to inate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
Air bags are designed to inate only once. After an
air bag inates, you will need some new parts for
your air bag system. If you do not get them, the air
bag system will not be there to help protect you
in another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
Your vehicle is equipped with electronic frontal
sensors which help the sensing system distinguish
between a moderate and a more severe frontal
impact. If your vehicle has side impact air bags,
it also has electronic side sensors. Your vehicle is
equipped with a crash sensing and diagnostic
module, which records information about the air bag
system. The module records information about
the readiness of the system and when the systemcommands air bag ination. It records the status of
the driver’s safety belt usage in a crash in which
the air bag deploys or a crash in which the air bag
nearly deploys. The module also records speed,
engine rpm, brake and throttle data.
Let only qualied technicians work on your air bag
system. Improper service can mean that your air
bag system will not work properly. See your dealer
for service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, or the side
impact air bag covering on the ceiling near the side
windows, the bag may not work properly. You may
have to replace the air bag module in the steering
wheel, both the air bag module and the instrument
panel for the right front passenger’s air bag, or
side impact air bag module and ceiling covering
for the roof-mounted side impact air bag. Do not
open or break the air bag coverings.

{CAUTION:
If the air bag readiness light ever comes on
when you have turned off the air bag, it means
that something may be wrong with the air bag
system. The right front passenger’s frontal air
bag could inate even though the switch is off.
If this ever happens, do not let anyone whom

member of a passenger air bag risk group
sit in the right front passenger’s position
(for example, do not secure a rear-facing child
restraint in the right front passenger’s seat)
until you have your vehicle serviced.
To turn the right front
passenger’s frontal air bag
on again, insert your
ignition key into the switch,
push in, and move the
switch to the auto position.
Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service
manual have information about servicing your vehicle
and the air bag systems.To purchase a service manual,
seeService Publications Ordering Information on
page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
air bag can still inate during improper service.
You can be injured if you are close to an air bag
when it inates. Avoid wires wrapped with
yellow tape or yellow connectors. They are
probably part of the air bag system. Be sure to
follow proper service procedures, and make
sure the person performing work for you is
qualied to do so.
The air bag systems do not need regular maintenance.

Remote Keyless Entry System
If equipped, the keyless entry system operates on a
radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.

qualied technician for service.
2-4

If the lock button on the remote keyless entry transmitter
is pressed, but a door is open, the horn will chirp six
times. Close the open door and the system will be
activated.
If a locked door is not opened with the remote keyless
entry transmitter, or OnStar
®, the alarm will go off.
The front turn signal lamps will ash for two minutes,
and the horn will sound for two minutes, then will turn off
to save the battery power.
Remember, the theft-deterrent system won’t activate if
you lock the doors with a key, the manual door lock, or
power door lock switch. The system can only be activated
with the remote keyless entry transmitter, or OnStar
®.
You should also remember that you can start your vehicle
with the correct ignition key if the alarm has been set off.
Here’s how to avoid setting off the alarm by accident:
If you don’t want to activate the theft-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.
Always unlock a door with a the remote keyless
entry transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, you can turn off
the alarm by pressing unlock on the remote keyless
entry transmitter. The alarm won’t stop if you try
to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, activate the system by
locking the doors with the remote keyless entry
transmitter.
2. Unlock the door with the manual door lock and
open the door. This should set off the alarm.
3. To turn the alarm off, press the unlock button on
the remote keyless entry transmitter or start the
engine.
If the alarm does not sound when it should but the lights
ash, check to see if the horn works. The horn fuse
may be blown. To replace the fuse, seeFuses and
Circuit Breakers on page 5-104.
If the alarm does not sound or the headlamps do not
ash, see your dealer for service.
2-15

Passlock®
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock®is a passive theft-deterrent system. Passlock®
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, the fuel system is
disabled and the vehicle will not start.
During normal operation, the security light will turn off
approximately ve seconds after the key is turned
to RUN. SeeSecurity Light on page 3-35.
If the engine stalls and the security light ashes, wait
about 10 minutes until the light stops ashing before
trying to restart the engine. Remember to release
the key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the engine
off. However, your Passlock
®system is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by Passlock
®at this time. You
may also want to check the fuse seeFuses and Circuit
Breakers on page 5-104. See your dealer for service.
In an emergency, call the GM Roadside Assistance
Center. SeeRoadside Assistance Program on page 7-6.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long run
if you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or less
for the rst 500 miles (805 km).
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km).
Do not make full-throttle starts.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-60for more information.
2-16

Ignition Positions
With the key in the ignition
switch, you can turn to four
different positions.
{CAUTION:
On manual transmission vehicles, turning the
key to LOCK will lock the steering column and
result in a loss of ability to steer the vehicle.
This could cause a collision. If you need to
turn the engine off while the vehicle is moving,
turn the key only to ACC. Do not push the key
in while the vehicle is moving.LOCK (A):This position locks your steering wheel,
ignition and transmission on automatic transmission
vehicles. If your vehicle has a manual transmission, this
position locks your steering wheel. It is a theft-deterrent
feature. You will only be able to remove your key
when the ignition is turned to LOCK.
If you have an automatic transmission, the ignition
switch cannot be turned to LOCK unless the shift lever
is in PARK (P).
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in. If
it is, turn the steering wheel left and right while you
turn the key hard. If none of this works, then
your vehicle needs service.
ACC (ACCESSORY) (B):This is the position in which
you can operate your electrical accessories or items
plugged into the accessory power outlets. It also unlocks
the steering wheel and ignition. Use this position if
your vehicle must be pushed or towed.
2-17

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.
