2010 GMC CANYON check engine

Testing the Alarm
To test the alarm:
1. From inside the vehicle, activate the system by
locking the doors with the RKE 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 RKE transmitter or start the engine.
If the alarm does not sound when it should but the lights
flash, check to see if the horn works. The horn fuse
may be blown. To replace the fuse, seeFuses and
Circuit Breakers on page 6-111.
If the alarm does not sound or the front turn
signal lamps do not flash, see your dealer/retailer
for service.
Passlock®(U.S. Only)
Passlock®is a passive theft-deterrent system that
enables fuel if the vehicle is started with a valid key.
If an incorrect key is used or the ignition lock cylinder is
tampered with, the fuel system is disabled and the
vehicle does not start.
The security light turns off approximately five seconds
after the engine is started. SeeSecurity Light on
page 4-32.
If the engine stalls and the security light flashes, wait
about 10 minutes until the light stops flashing before
trying to restart the engine. 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,
the engine restarts if you turn the engine off. However,
the Passlock
®system is not working properly and
must be serviced by your dealer/retailer. The vehicle is
not protected by Passlock
®at this time. See your
dealer/retailer for service.
In an emergency, call the Roadside Assistance Center.
SeeRoadside Assistance Program on page 8-7.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

information regarding Part 15 of the Federal
Communications Commission (FCC) Rules and
RSS-210/211 of Industry and Science Canada.
PASS-Key®III+ Electronic
Immobilizer Operation
(Canada Only)
This vehicle has a passive theft-deterrent system.
The system is automatically armed when the key is
removed from the ignition.
The system is automatically disarmed when the key is
turned to ON/RUN.
You do not have to manually arm or disarm the system.
The security light comes on if there is a problem with
arming or disarming the theft-deterrent system.
The key uses a transponder that matches an immobilizer
control unit in the vehicle. Only the correct key starts
the vehicle. If the key is ever damaged, the vehicle may
not start.When trying to start the vehicle, if the engine does not
start and the security light comes on, there may be
a problem with the theft-deterrent system. Turn the
ignition off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. Check the
fuse. SeeFuses and Circuit Breakers on page 6-111.
If the engine still does not start with the other key, the
vehicle needs service. If the vehicle does start, the
first key may be faulty. See your dealer/retailer who can
service the theft-deterrent system and have a new
key made.
It is possible for the theft-deterrent system decoder to
learn the transponder value of a new or replacement
key. Up to 10 keys can be programmed for the vehicle.
The following procedure is for programming additional
keys only.
Canadian Owners:If the keys are lost or damaged,
only a dealer/retailer can service the theft-deterrent
system to have new ones made. Two current driver’s
keys are required to program additional keys.
To program a new key:
1. Verify that the new key has PK3+ stamped on it.
2. Insert the current driver’s key in the ignition
and start the engine. If the engine does not start
see your dealer/retailer for service.

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as the
engine warms. Do not race the engine immediately
after starting it. Operate the engine and
transmission gently to allow the oil to warm up and
lubricate all moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects components. If the ignition key
is turned to the START position, and then
released when the engine begins cranking, the
engine will continue cranking for a few seconds or
until the vehicle starts. If the engine does not
start and the key is held in START for many
seconds, cranking will be stopped after 15 seconds
to prevent cranking motor damage. To prevent
gear damage, this system also prevents cranking if
the engine is already running. Engine cranking
can be stopped by turning the ignition switch
to ACC/ACCESSORY or LOCK/OFF.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or
−18°C), it could be flooded with too much gasoline.
Push the accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool. When the engine starts,
let go of the key and accelerator. If the vehicle starts
briefly but then stops again, repeat the procedure.
This clears the extra gasoline from the engine.
Do not race the engine immediately after starting it.
Operate the engine and transmission gently until
the oil warms up and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.

The recirculation mode cannot be used with floor/defog,
defrost, or defogging modes. If recirculation is selected in
these modes, the indicator will flash or not come on.
Outlet Adjustment
Use the thumbwheel on the outlets to change the
direction of the air flow.
Lift up or push down on the thumbwheel located in the
center of the outlet to direct the air up or down, or
slide the thumbwheel to the left or right to direct the
airflow from side-to-side.
Operation Tips
•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into the vehicle.
•Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•Keep the path under the front seats clear of objects
to help circulate the air inside of the vehicle more
effectively.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something
is wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention
to the warning lights and gages could prevent injury.
Warning lights come on when there might be or there
is a problem with one of the vehicle’s functions. Some
warning lights come on briefly when the engine is started
to indicate they are working.
Gages can indicate when there might be or there is a
problem with one of the vehicle’s functions. Often gages
and warning lights work together to indicate a problem
with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
could be a problem, check the section that explains
what to do. Follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.

Speedometer and Odometer
The speedometer shows the speed in both miles per
hour (mph) and kilometers per hour (km/h).
The odometer shows how far the vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
The odometer mileage can be checked without the
vehicle running by pressing the trip information stem.
See “Odometer” underDIC Operation and Displays
on page 4-33for more information.
If the cluster is replaced the new one will automatically
detect and update the vehicle’s accumulated mileage.
Trip Odometer
The vehicle has a trip odometer that indicates how far
the vehicle has been driven since the trip odometer was
last set to zero.
See “Trip Odometer” underDIC Operation and Displays
on page 4-33for more information.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
Notice:If the engine is operated with the
tachometer in the shaded warning area, the vehicle
could be damaged, and the damages would not
be covered by the vehicle warranty. Do not operate
the engine with the tachometer in the shaded
warning area.

Airbag Readiness Light
The system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check includes
the airbag sensor, the pretensioners, the airbag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the airbag system, seeAirbag
System on page 2-64.
The airbag readiness light
flashes for a few seconds
when the engine is started.
If the light does not come
on then, have it fixed
immediately.{WARNING:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also come
on. SeeDIC Warnings and Messages on page 4-37for
more information.

Charging System Light
This light comes on briefly
when the ignition key is
turned to START, 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.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
SeeDIC Warnings and Messages on page 4-37for more
information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light
on, turn off accessories, such as the radio and air
conditioner.
Up-Shift Light
The vehicle may have an
up-shift light.
When this light comes on, shift to the next higher gear if
weather, road, and traffic conditions allow.
SeeManual Transmission Operation on page 3-23for
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.
