2008 GMC Canyon Owner ManualM

If the Light is Flashing
The following can prevent more serious damage to your
vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the ignition off, wait at least 10 seconds, and restart
the engine. If the light remains on steady, see “If the
Light Is On Steady” following. If the light is still ashing,
follow the previous steps and see your dealer/retailer
for service as soon as possible.
If the Light Is On Steady
You might be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 5-8.
The diagnostic system can determine if the fuel caphas been left off or improperly installed. A loose or
missing fuel cap allows fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water?
If so, your vehicle’s electrical system might be wet. The
condition is usually corrected when the electrical system
dries out. A few driving trips should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. Poor fuel quality causes
the engine not to run as efficiently as designed. You
might notice this as stalling after start-up, stalling when
you put the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration — these
conditions might go away once the engine is warmed up.
This will be detected by the system and cause the light to
turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn
off, your dealer/retailer can check the vehicle. Your
dealer/retailer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that might have developed.

Fuel Gage
When the ignition is on,
the fuel gage tells you
about how much fuel you
have remaining in the
fuel tank.
Here are four things that some owners ask about.
None of these indicate a problem with your fuel gage:
At the gas station, the gas pump shuts off before
the gage reads full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank’s capacity to
ll the tank.
The gage moves a little when you turn a corner or
speed up.
The gage does not go back to empty when you turn
off the ignition.When the fuel in the fuel tank is low, you will see
a LOW FUEL message on the Driver Information
Center (DIC) display. SeeDIC Warnings and Messages
on page 3-42for more information.
Driver Information Center (DIC)
The Driver Information Center (DIC) displays information
such as the trip odometer, personalization features,
and warning messages. The DIC display is located
on the instrument panel cluster.
DIC Operation and Displays
The Driver Information Center (DIC) comes on when the
ignition is on.
If a problem is detected, a warning message appears
on the display. Pressing and releasing the trip odometer
reset stem on the DIC acknowledges some current
warnings or service messages. Some messages only
clear after the required action has been taken.
The DIC has different modes which can be accessed by
pressing the trip odometer reset stem on the DIC. These
modes are explained in the following section. The DIC trip
odometer reset stem is located on the instrument panel
cluster next to the DIC display. To scroll through the
available functions, press and release the reset stem.
3-38

DOORS
This message displays when one or more of the doors
is ajar. Check all the doors on your vehicle to make
sure they are closed. The message clears from
the display after all of the doors are closed.
ENG (Engine) HOT
This message displays when the engine coolant
temperature is hot. Check the engine coolant
temperature gage. SeeEngine Coolant Temperature
Gage on page 3-33. Have your vehicle serviced by your
dealer/retailer as soon as possible if you suspect the
engine is overheating. SeeEngine Overheating on
page 5-29for more information.
FLUID
This message displays if the brake uid is low. Check
the brake uid as soon as possible and have your
vehicle serviced by your dealer/retailer. SeeBrakes on
page 5-38for more information. Press and release the
reset stem to acknowledge the message and clear it
from the display.
FUEL CAP
This message displays if the vehicle’s fuel cap is either off
or loose. Pull over as soon as possible and check to see
if the fuel cap is secure. You may also see the check
engine light on the instrument panel cluster. If the check
engine light does come on when the fuel cap was loose,
it may take a few driving trips before the light turns off.
SeeMalfunction Indicator Lamp on page 3-34for more
information if the light still remains on. Press and release
the reset stem to acknowledge the message and clear it
from the display.
LOW FUEL
This message displays if the level of fuel in the vehicle
is low. Also check the fuel gage. SeeFuel Gage on
page 3-38for more information. Rell the fuel tank
as soon as possible.
LOW TIRE
This message displays if a low tire pressure is detected in
any of the vehicle’s tires. Press and release the reset
stem to acknowledge the message and clear it from the
display. The message appears at each ignition cycle until
the tires are inated to the correct ination pressure.
SeeTires on page 5-56andInflation - Tire Pressure on
page 5-62for more information on tires and the correct
ination pressures.

Refer to your vehicle’s Tire and Loading

your vehicle’s capacity weight and seating
positions. The combined weight of the driver,
passengers, cargo, and any accessories orequipment added to your vehicle after it left the
factory should never exceed your vehicle’s
capacity weight.
Certication/Tire Label
A vehicle specic Certication/Tire label is attached
to the bottom section of the center pillar, on the
driver’s side of the vehicle. Vehicles without a
center pillar, like extended cab models, will have
the Certication/Tire label attached to the edge of
the driver’s side, extended cab door, below the
door latch post. The label shows the Gross Vehicle
Weight Rating (GVWR). The GVWR includes the
weight of the vehicle, all occupants, fuel, cargo,
and trailer tongue weight, if pulling a trailer.

Towing a Trailer
{CAUTION:
If you do not use the correct equipment and
drive properly, you can lose control when you
pull a trailer. For example, if the trailer is too
heavy, the brakes may not work well — or even
at all. You and your passengers could be
seriously injured. You may also damage your
vehicle; the resulting repairs would not be
covered by your warranty. Pull a trailer only if
you have followed all the steps in this section.
Ask your dealer/retailer for advice and
information about towing a trailer with
your vehicle.Notice:Pulling a trailer improperly can damage
your vehicle and result in costly repairs that would
not be covered by your warranty. Always follow
the instructions in this section and check with your
dealer/retailer for more information about towing
a trailer with your vehicle.
To identify the trailering capacity of your vehicle, you
should read the information in “Weight of the Trailer” that
appears later in this section.
Trailering is different than just driving your vehicle
by itself. Trailering means changes in handling,
acceleration, braking, durability and fuel economy.
Successful, safe trailering takes correct equipment,
and it has to be used properly.
That’s the reason for this part. In it are many time-tested,
important trailering tips and safety rules. Many of
these are important for your safety and that of your
passengers. So please read this section carefully before
you pull a trailer.
