light GMC CANYON 2007 Service Manual

Exit Lighting
With exit lighting, the interior lamps will come on
when you remove the key from the ignition.
The lamps will not come on if the dome override
button is pressed in.
Electric Power Management
The vehicle has Electric Power Management
(EPM) that estimates the battery’s temperature and
state of charge. It then adjusts the voltage for
best performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage, you may
see the voltage move up or down. This is normal.
If there is a problem, an alert will be displayed.The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very high
electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
Battery Run-Down Protection
This feature shuts off the dome lamp if it is left on
for more than 20 minutes when the ignition is
in LOCK. This will help prevent your battery from
running down.

Ashtray(s) and Cigarette Lighter
Your vehicle may have an ashtray and cigarette
lighter.
Your ashtray is located in your center console
area. The ashtray can be removed for cleaning.
When the ashtray is removed, this area can
also be used as a cupholder.
Notice:If you put papers, pins, or other
ammable items in the ashtray, hot cigarettes
or other smoking materials could ignite
them and possibly damage your vehicle.
Never put ammable items in the ashtray.
To use the lighter, press it in all the way, and let
go. When it’s ready, it will pop back out by itself.
Notice:Holding a cigarette lighter in while it
is heating will not allow the lighter to back
away from the heating element when it is hot.
Damage from overheating may occur to the
lighter or heating element, or a fuse could be
blown. Do not hold a cigarette lighter in
while it is heating.
Climate Controls
Climate Control System
With this system you can control the heating,
cooling, and ventilation for your vehicle.
Temperature Knob
The left knob on the control panel is used to
adjust the temperature of the air in the vehicle.
Turn the knob clockwise or counterclockwise
to increase or decrease the temperature.
173

Fan Knob
9
(Fan):The center knob on the control panel
is used to control the fan speed. Turn the
knob clockwise or counterclockwise to increase or
decrease the fan speed.
If the knob is set on “0” (zero), some outside air
will still enter the vehicle and will be directed
according to the position of the mode knob.
Mode Knob
The right knob on the control panel is used to
direct the airow inside your vehicle. Turn the knob
to select one of the following modes:
H(Vent):Select this mode to direct air to the
instrument panel outlets.
\(Bi-Level):Select this mode to direct
approximately half of the air to the instrument
panel outlets, and the remaining air to the
oor outlets and the defroster and side window
outlets. Cooler air is directed to the upper outlets
and warmer air to the oor outlets.
[(Floor):Select this mode to direct air to the
oor outlets. Recirculation is disabled in this mode
because interior window could fog under some
conditions. If this occurs, see “Defogging and
Defrosting” following.
Mode Buttons
@
(Recirculation):This mode recirculates air
inside the cabin, and prevents outside air from
coming in the vehicle. It can be used to prevent
outside odors from entering your vehicle and
cool the air inside your vehicle more quickly. Press
this button to turn the recirculation mode on or
off. An indicator light on the button will come on to
let you know the recirculation mode is activated.
Recirculation is only available in the bi-level
and vent modes. It should only be used while in
bi-level and vent modes. Recirculation is not
available, and the light will not come on or ash
while in heat, oor, oor/defog, or defrost modes.
174

#(Air Conditioning):Press this button to turn
the air conditioning system on or off. An indicator
light on the button will come on to let you know
the air conditioning is activated. When the system
is on, this setting cools and dehumidies the
air entering your vehicle.
The air conditioning will not function if the fan is
turned off.
You may notice a slight change in engine
performance when the air conditioning compressor
shuts off and turns on again. This is normal.
The system is designed to make adjustments to
help with fuel economy while still maintaining
the selected temperature.
The air conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your
vehicle while idling or after turning off the engine.
This is normal.Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool
window glass. This can be minimized if the
climate control system is used properly. There
are two modes to clear fog or frost from your
windshield and side windows. Use the defog mode
to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more
quickly. For best results, clear all snow and ice
from the windshield before defrosting.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be on your vehicle. The pictures will
help you locate them.
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 your warning
lights and gages could also save you or others
from injury.
Warning lights come on when there may be or
is a problem with one of your vehicle’s functions.
As you will see in the details on the next few
pages, some warning lights come on briey when
you start the engine just to let you know they
are working. If you are familiar with this section,
you should not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions.
Often gages and warning lights work together to
let you know when there is a problem with
your vehicle.
When one of the warning lights comes on and
stays on when you are driving, or when one of
the gages shows there may be a problem, check
the section that tells you what to do about it.
Please follow this manual’s advice. Waiting to
do repairs can be costly — and even dangerous.
So please get to know your warning lights and
gages. They are a big help.
Your vehicle has a DIC that works along with the
warning lights and gages. SeeDriver Information
Center (DIC) on page 194for more information.

Safety Belt Reminder Light
When the key is turned to ON or START, a chime
will be provided for several seconds to remind
people to buckle their safety belts. The driver
safety belt light will also be provided and stay on
for several seconds, then it will ash for several
more. You should buckle your seat belt.
This chime and light will
be repeated if the driver
remains unbuckled
and the vehicle
is in motion.
If the driver’s belt is buckled, neither the chime nor
the light will be provided.
Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to ON or
START, a chime will sound for several seconds
to remind the front passenger to buckle their safety
belt. This would only occur if the passenger
airbag is enabled. SeePassenger Sensing System
on page 86for more information. The passenger
safety belt light will also come on and stay on
for several seconds, then it will ash for several
more. You should have the passenger buckle their
seat belt.
This chime and light will
be repeated if the
passenger remains
unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
180

Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical
system for malfunctions. The light tells you if there
is an electrical problem. The system check
includes the airbag sensors, the airbag modules,
the wiring and the crash sensing and diagnostic
module. For more information on the airbag
systems, seeAirbag System on page 76.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
The airbag readiness light should ash for a few
seconds when you turn the ignition key to ON.
If the light does not come on then, have it xed so
it will be ready to warn you if there is a problem.
181

Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your instrument panel has a passenger airbag
status indicator.
When the ignition key is turned to ON or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. Then,
after several more seconds, the status indicator
will light either ON or OFF, or either the on
or off symbol to let you know the status of the
right front passenger’s frontal airbag.There is a label on your sun visor that says,
“Never put a rear-facing child seat in the front.”
This is because the risk to the rear-facing child is
so great if the airbag deploys.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.

If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together,
it means that something may be wrong
with the airbag system. If this ever
happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger seat
may not have the protection of the frontal
airbag. SeeAirbag Readiness Light
on page 181.
Battery Warning Light
This light will come on
briey when you start
the vehicle, as a
check to show you it is
working; then it
should go out.
If it stays on, or comes on while you are driving,
you may have a problem with the electrical
charging system. Have it checked right away.
Driving while this light is on could drain your
battery and result in a vehicle that may stall. See
DIC Warnings and Messages on page 198for
more information.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and climate control system.
184

Up-Shift Light
(Manual Transmission)
This light appears when
you need to shift to the
next higher gear on
a manual transmission
vehicle.
Shifting when the indicator light is on will help you
get the best fuel economy. See “Up-Shift Light”
underManual Transmission Operation on
page 124for more information.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good
braking, though, you need both parts working well.
If the warning light comes on, there could be a
brake problem. Have your brake system inspected
right away.
This light should come on briey when you turn
the ignition key to ON. If it does not come on then,
have it xed so it will be ready to warn you if
there is a problem.
