brake GMC CANYON 2009 Owner's Guide

Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work. The brakes might
vibrate or some noise might be heard, but this is normal.
Braking in Emergencies
ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more than
even the very best braking.
Brake Assist
This vehicle has a Brake Assist feature designed to
assist the driver in stopping or decreasing vehicle speed
in emergency driving conditions. This feature uses the
stability system hydraulic brake control module to
supplement the power brake system under conditions
where the driver has quickly and forcefully applied the
brake pedal in an attempt to quickly stop or slow down
the vehicle. The stability system hydraulic brake control
module increases brake pressure at each corner of the
vehicle until the ABS activates. Minor brake pedal
pulsations or pedal movement during this time is normal
and the driver should continue to apply the brake pedal
as the driving situation dictates The Brake Assist feature
will automatically disengage when the brake pedal is
released or brake pedal pressure is quickly decreased.
StabiliTrak®System
The vehicle has an electronic stability control system
called StabiliTrak. It is an advanced computer controlled
system that assists the driver with directional control of
the vehicle in difficult driving conditions.
StabiliTrak activates when the computer senses a
discrepancy between the intended path and the direction
the vehicle is actually traveling. StabiliTrak selectively
applies braking pressure at any one of the vehicle’s
brakes to assist the driver with keeping the vehicle on
the intended path.
When the vehicle is started and begins to move, the
system performs several diagnostic checks to insure
there are no problems. The system may be heard or felt
while it is working. This is normal and does not mean
there is a problem with the vehicle. The system should
initialize before the vehicle reaches 20 mph (32 km/h).
In some cases, it may take approximately two miles of
driving before the system initializes.
If cruise control is being used when StabiliTrak activates,
the cruise control automatically disengages. The cruise
control can be re-engaged when road conditions allow.
SeeCruise Control on page 3-10.
4-6

If there is a problem detected with StabiliTrak, a
SERVICE STAB SYS message displays on the Driver
Information Center (DIC). SeeDIC Warnings and
Messages on page 3-38for more information. When this
message is displayed, the system is not working.
Adjust your driving accordingly.
StabiliTrak and Traction Control (TCS) come on
automatically whenever the vehicle is started and the
systems are reset with each ignition cycle. However,
when the transfer case is placed in Four-Wheel-Low
mode, StabiliTrak is automatically disabled. See
Four-Wheel Drive on page 2-26for more information. It is
recommended to leave the system on for normal driving
conditions, but it may be necessary to turn the TCS
portion of the system off if the vehicle is stuck in sand,
mud, ice, or snow, and it is necessary to″rock″the
vehicle to attempt to free it. If traction control is turned off,
only the brake-traction control portion of traction control
will work. The engine speed management will be
disabled. In this mode, engine power is not reduced
automatically and the drive wheels can spin more freely.
This can cause the brake-traction control to activate
constantly. SeeIf Your Vehicle is Stuck in Sand, Mud,
Ice, or Snow on page 4-31.The StabiliTrak/TCS light
will ash on the instrument
panel cluster when the
TCS system or StabiliTrak
is both on and activated.
The StabiliTrak/TCS
button is located on
the instrument panel.
To turn off TCS, press and release the StabiliTrak/TCS
button. The StabiliTrak/TCS light comes on in the
instrument panel cluster, and TRAC OFF comes on
the DIC. To turn TCS back on, press and release the
StabiliTrak/TCS button.
4-7

To turn off TCS and StabiliTrak, press and hold the
StabiliTrak/TCS button until the TRAC OFF and
STAB SYS OFF messages come on the DIC and the
StabiliTrak/TCS light comes on the instrument panel.
To turn TCS and StabiliTrak back on, press and release
the StabiliTrak/TCS button.
When the TCS or StabiliTrak system is turned off, the
StabiliTrak/TCS light and the appropriate TRAC OFF or
STAB SYS OFF message will be displayed on the DIC.
The vehicle will still have brake-traction control when TCS
or StabiliTrak is off, but will not be able to use the engine
speed management system. The StabiliTrak/TCS light
ashes when either system is actively working. See
Traction Control Operation following for more information.
Traction Control System (TCS)
The Traction Control System (TCS) is part of StabiliTrak.
TCS limits wheel slip which is especially useful in slippery
road conditions. The system operates only if it senses
that any of the wheels are spinning or beginning to lose
traction. When this happens, TCS applies the brakes to
limit wheel spin and also reduces engine power. The
system may be heard or felt while it is working. This is
normal and does not mean there is a problem with the
vehicle.Notice:If the wheel(s) of one axle is allowed to
spin excessively while the StabiliTrak, ABS
and brake warning lights and any relevant DIC
messages are displayed, the transfer case could be
damaged. The repairs would not be covered by
the vehicle warranty. Reduce engine power and do
not spin the wheel(s) excessively while these
lights and messages are displayed.
TCS can operate on dry roads under some conditions.
When this happens, the system may be heard
working or a reduction in acceleration may be noticed.
This is normal and does not mean there is a problem
with the vehicle. Examples of these conditions include
hard acceleration in a turn, an abrupt upshift or
downshift of the transmission or driving on rough roads.
If cruise control is being used when TCS begins to
limit wheel spin, the cruise control automatically
disengages. The cruise control can be re-engaged
when road conditions allow. SeeCruise Control
on page 3-10.
4-8

The message TRACTION FAULT appears in the Driver
Information Center (DIC) when a TCS or Antilock Brake
System (ABS) problem has been detected and the
vehicle needs service. When this message is on, the
system will not limit wheel spin. Adjust your driving
accordingly. SeeDIC Warnings and Messages on
page 3-38.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3.
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle can give more
traction on snow, mud, ice, sand or gravel. It works like
a standard axle most of the time, but when traction
is low, this feature allows the drive wheel with the most
traction to move the vehicle.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
It is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and your speed. While in a curve, speed is the
one factor you can control.
If you need to reduce speed, do it before you enter the
curve, while the front wheels are straight ahead.
Try to adjust the speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait
to accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
4-9

Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and nd
a truck stopped in your lane, or a car suddenly pulls out
from nowhere, or a child darts out from between parked
cars and stops right in front of you. You can avoid these
problems by braking — if you can stop in time. But
sometimes you cannot; there is not room. That is the time
for evasive action — steering around the problem.
Your vehicle can perform very well in emergencies like
these. First apply the brakes. SeeBraking on page 4-4.
It is better to remove as much speed as you can from a
possible collision. Then steer around the problem, to the
left or right depending on the space available.
An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o’clock positions, you can turn
it a full 180 degrees very quickly without removing either
hand. But you have to act fast, steer quickly, and just as
quickly straighten the wheel once you have avoided the
object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving
at all times and wear safety belts properly.
4-10

Off-Road Recovery
The vehicle’s right wheels can drop off the edge of a
road onto the shoulder while driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way, steer
so that your vehicle straddles the edge of the pavement.
Turn the steering wheel 3 to 5 inches, 8 to 13 cm, (about
one-eighth turn) until the right front tire contacts the
pavement edge. Then turn the steering wheel to go
straight down the roadway.
Passing
Passing another vehicle on a two-lane road can be
dangerous. To reduce the risk of danger while passing:
Look down the road, to the sides, and to crossroads
for situations that might affect a successful pass.
If in doubt, wait.
Watch for traffic signs, pavement markings, and
lines that could indicate a turn or an intersection.
Never cross a solid or double-solid line on your
side of the lane.
Do not get too close to the vehicle you want to
pass. Doing so can reduce your visibility.
Wait your turn to pass a slow vehicle.
When you are being passed, ease to the right.
Loss of Control
Let us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough friction
where the tires meet the road to do what the driver has
asked.
In any emergency, do not give up. Keep trying to
steer and constantly seek an escape route or area of
less danger.
4-11

Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not overdriving
those conditions. But skids are always possible.
The three types of skids correspond to your vehicle’s
three control systems. In the braking skid, the wheels are
not rolling. In the steering or cornering skid, too much
speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.
If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
your vehicle may straighten out. Always be ready
for a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance is longer and
vehicle control more limited.While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by shifting to a
lower gear. Any sudden changes could cause the tires to
slide. You might not realize the surface is slippery until
your vehicle is skidding. Learn to recognize warning
clues — such as enough water, ice, or packed snow on
the road to make a mirrored surface —and slow down
when you have any doubt.
Remember: Any Antilock Brake System (ABS) helps
avoid only the braking skid.
Off-Road Driving
Vehicles with four-wheel drive can be used for off-road
driving. Vehicles without four-wheel drive should not
be driven off-road except on a level, solid surface.
The airbag system is designed to work properly under a
wide range of conditions, including off-road usage.
Always wear your safety belt and observe safe driving
speeds, especially on rough terrain.
4-12

Attach a ag to the vehicle to be more visible to
approaching traffic on trails or hills.
Sound the horn as you approach the top of the hill
to let opposing traffic know you are there.
Use headlamps even during the day to make the
vehicle more visible to oncoming traffic.
{CAUTION:
Driving to the top (crest) of a hill at full speed can
cause an accident. There could be a drop-off,
embankment, cliff, or even another vehicle. You
could be seriously injured or killed. As you near
the top of a hill, slow down and stay alert.If the vehicle stalls, or is about to stall, and you cannot
make it up the hill:
Push the brake pedal to stop the vehicle and keep
it from rolling backwards and apply the parking
brake.
If the engine is still running, shift the transmission to
R (Reverse), release the parking brake, and slowly
back down the hill in R (Reverse).
If the engine has stopped running, you need to
restart it. With the brake pedal pressed and the
parking brake still applied, shift the automatic
transmission to P (Park) or the manual transmission
to Neutral and restart the engine. Then, shift to
R (Reverse), release the parking brake, and slowly
back down the hill as straight as possible in
R (Reverse).
While backing down the hill, put your left hand on the
steering wheel at the 12 o’clock position so you can
tell if the wheels are straight and can maneuver as
you back down. It is best to back down the hill with
the wheels straight rather than in the left or right
direction. Turning the wheel too far to the left or right
will increase the possibility of a rollover.
4-19

Things not to do if the vehicle stalls, or is about to stall,
when going up a hill:
Never attempt to prevent a stall by shifting into
N (Neutral), or pressing the clutch pedal if the
vehicle has a manual transmission, to rev-up the
engine and regain forward momentum. This will not
work. The vehicle can roll backward very quickly
and could go out of control.
Never try to turn around if about to stall when going
up a hill. If the hill is steep enough to stall the vehicle,
it is steep enough to cause it to roll over. If you
cannot make it up the hill, back straight down the hill.
If, after stalling, you try to back down the hill and decide
you just cannot do it, set the parking brake, shift to
P (Park) or 1 (First) with a manual transmission, and turn
off the engine. Leave the vehicle and go get some help.Exit on the uphill side and stay clear of the path the
vehicle would take if it rolled downhill. Do not shift the
transfer case to Neutral when you leave the vehicle.
Leave it in some gear.
{CAUTION:
Shifting the transfer case to Neutral can cause
your vehicle to roll even if the transmission is in
P (Park). This is because the Neutral position on
the transfer case overrides the transmission.
You or someone else could be injured. If you are
going to leave your vehicle, set the parking brake
and shift the transmission to P (Park). But do not
shift the transfer case to Neutral.

Driving Downhill
When off-roading takes you downhill, consider:
How steep is the downhill? Will I be able to maintain
vehicle control?
What is the surface like? Smooth? Rough?
Slippery? Hard-packed dirt? Gravel?
Are there hidden surface obstacles? Ruts? Logs?
Boulders?
What is at the bottom of the hill? Is there a hidden
creek bank or even a river bottom with large rocks?
If you decide you can go down a hill safely, try to keep
the vehicle headed straight down. Use a low gear
so engine drag can help the brakes so they do not have
to do all the work. Descend slowly, keeping the
vehicle under control at all times.
{CAUTION:
Heavy braking when going down a hill can cause
your brakes to overheat and fade. This could cause
loss of control and a serious accident. Apply the
brakes lightly when descending a hill and use a low
gear to keep vehicle speed under control.Things not to do when driving down a hill:
When driving downhill, avoid turns that take you
across the incline of the hill. A hill that is not too
steep to drive down might be too steep to drive
across. The vehicle could roll over.
Never go downhill with the transmission in
N (Neutral), called free-wheeling. The brakes will
have to do all the work and could overheat
and fade.
Vehicles are much more likely to stall when going uphill,
but if it happens when going downhill:
1. Stop the vehicle by applying the regular brakes and
apply the parking brake.
2. Shift to P (Park) and, while still braking, restart the
engine.
3. Shift back to a low gear, release the parking brake,
and drive straight down.
4. If the engine will not start, get out and get help.
