2010 GMC CANYON service

If the StabiliTrak system and TCS light comes on and
stays on while driving and a TRACTION FAULT or
SERVICE STAB SYS message displays on the DIC,
the vehicle needs service.
The light also comes on steady when the StabiliTrak
system and/or TCS are turned off. The DIC also displays
a TRAC OFF and/or STAB SYS OFF message. If the
TCS is off, wheel spin is not limited. If the StabiliTrak
system is off, the system does not assist the driver with
directional control of the vehicle. The light turns off when
the TCS and StabiliTrak system are turned back on.

Messages on page 4-37for more information.
Engine Coolant Temperature Gage
This gage shows
the engine coolant
temperature.
If the gage pointer is near the top of the gage, the
engine is too hot. It means that the engine coolant has
overheated. If the vehicle has been operating under
normal driving conditions, pull the vehicle off the road,
stop the vehicle and turn off the engine as soon as
possible.
SeeEngine Overheating on page 6-35for more
information.

Tire Pressure Light
For vehicles with a tire pressure monitoring system,
this light comes on briefly when the engine is started.
It provides information about tire pressures and the
Tire Pressure Monitoring System.
When the Light is On Steady
This indicates that one or more of the tires are
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC) on page 4-33for more
information. Stop and check the tires as soon as
it is safe to do so. If underinflated, inflate to the proper
pressure. SeeInation - Tire Pressure on page 6-64
for more information.
When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light flashes for about a
minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. SeeTire Pressure Monitor Operation on page 6-67
for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels
for the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working. If it does not,
have the vehicle serviced
by your dealer/retailer.
4-28

If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle.
This system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with
this light on, after a while, the emission controls
might not work as well, the vehicle’s fuel economy
might not be as good, and the engine might not
run as smoothly. This could lead to costly repairs
that might not be covered by the vehicle warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system
of the vehicle or the replacement of the original
tires with other than those of the same Tire
Performance Criteria (TPC) can affect the vehicle’s
emission controls and can cause this light to come
on. Modications to these systems could lead to
costly repairs not covered by the vehicle warranty.
This could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 6-3.This light comes on during a malfunction in one of
two ways:
Light Flashing:A misfire condition has been detected.
A misfire increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
To prevent more serious damage to the vehicle:
•Reduce vehicle speed.
•Avoid hard accelerations.
•Avoid steep uphill grades.
•If towing a trailer, reduce the amount of cargo being
hauled as soon as it is possible.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still flashing, follow the previous
steps and see your dealer/retailer for service as soon
as possible.
4-29

Light On Steady:An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required.
An emission system malfunction might be corrected by
doing the following:
•Make sure the fuel cap is fully installed. SeeFilling
the Tank on page 6-8. The diagnostic system
can determine if the fuel cap has 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.
•If the vehicle has been driven through a deep puddle
of water, the 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.
•Make sure to fuel the vehicle with quality fuel. Poor
fuel quality causes the engine not to run as efficiently
as designed and can cause: stalling after start-up,
stalling when the vehicle is changed into gear,
misfiring, hesitation on acceleration, or stumbling on
acceleration. These conditions might go away once
the engine is warmed up.
If one or more of these conditions occurs, change the
fuel brand used. It will require at least one full tank of
the proper fuel to turn the light off.
SeeGasoline Octane on page 6-5.
If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to
fix any mechanical or electrical problems that might have
developed.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
•The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if the
key is in ON/RUN and the light is not on.
•The vehicle will not pass this inspection if the OBD II
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if the battery has recently been replaced or if the
battery has run down. The diagnostic system is
designed to evaluate critical emission control
systems during normal driving. This can take several
days of routine driving. If this has been done and the
vehicle still does not pass the inspection for lack of
OBD II system readiness, your dealer/retailer can
prepare the vehicle for inspection.
Oil Pressure Light
{WARNING:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
This light comes on briefly while starting the engine.
If it does not, have the vehicle serviced by your dealer/
retailer. If the system is working normally the indicator
light then goes off.
4-31

An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
Here are four things that some owners ask about.
None of these indicate a problem with the vehicle’s
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 fill 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 fill the tank.
•The gage moves a little while turning a corner or
speeding up.
•The gage does not go back to empty when the
ignition is turned off.
When the fuel in the fuel tank is low, a LOW FUEL
message will display on the Driver Information
Center (DIC). SeeDIC Warnings and Messages
on page 4-37for 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
