2007 GMC ACADIA ignition

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. If the light does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and could damage the emission
control system on your vehicle. Diagnosis and
service might be required.
Light On Steady— An emission control
system malfunction has been detected on
your vehicle. Diagnosis and service might be
required.
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 key 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 390.
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.

Fuel Gage
When the ignition is on, the fuel gage tells you
about how much fuel you have left in your tank.
The gage will rst indicate empty before you
are out of fuel, and you should get more fuel as
soon as possible.When the fuel tank is low on fuel, the FUEL
LEVEL LOW message will appear on the
Driver Information Center (DIC). For more
information seeDIC Warnings and Messages
on page 244.
Here are some situations you may experience with
your fuel gage. None of these indicate a problem
with the fuel gage.
At the gas station, the fuel pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the fuel 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 goes back to empty when you turn
off the ignition.

Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
The DIC displays information about your vehicle.
It also displays warning messages if a system
problem is detected.
All messages will appear in the DIC display
located at the top of the instrument panel cluster.
The DIC comes on when the ignition is on.
After a short delay, the DIC will display the
information that was last displayed before the
engine was turned off.
The DIC also displays a shift lever position
indicator on the bottom line of the display. See
Automatic Transmission Operation on page 129
for more information.The outside air temperature also displays on the
DIC when viewing the trip and fuel information.
The outside air temperature automatically
appears in the top right corner of the DIC display.
If there is a problem with the system that
controls the temperature display, the numbers
will be replaced with dashes. If this occurs,
have the vehicle serviced.
If your vehicle has DIC buttons, see “DIC Operation
and Displays (With DIC Buttons)” later in this
section andDIC Vehicle Customization (With DIC
Buttons) on page 255for the displays available.
If your vehicle does not have DIC buttons, see
“DIC Operation and Displays (Without DIC
Buttons)” later in this section for the displays
available.

Trip/Fuel Menu Items
3
(Trip/Fuel):Press this button to scroll
through the following menu items:
ODOMETER
Press the trip/fuel button until ODOMETER
displays. This display shows the distance the
vehicle has been driven in either miles (mi)
or kilometers (km). Pressing the trip odometer
reset stem will also display the odometer.
To switch between English and metric
measurements, see “UNITS” later in this section.
TRIP A and TRIP B
Press the trip/fuel button until TRIP A or TRIP B
displays. This display shows the current distance
traveled in either miles (mi) or kilometers (km)
since the last reset for each trip odometer. Both
trip odometers can be used at the same time.
Pressing the trip odometer reset stem will
also display the trip odometers.Each trip odometer can be reset to zero separately
by pressing the set/reset button or the trip odometer
reset stem while the desired trip odometer is
displayed.
The trip odometer has a feature called the
retro-active reset. This can be used to set the
trip odometer to the number of miles (kilometers)
driven since the ignition was last turned on.
This can be used if the trip odometer is not reset
at the beginning of the trip.
To use the retro-active reset feature, press and
hold the set/reset button for at least four seconds.
The trip odometer will display the number of
miles (mi) or kilometers (km) driven since the
ignition was last turned on and the vehicle
was moving. Once the vehicle begins moving,
the trip odometer will accumulate mileage.
For example, if the vehicle was driven 5 miles
(8 km) before it is started again, and then
the retro-active reset feature is activated, the
display will show 5 miles (8 km). As the vehicle
begins moving, the display will then increase
to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
237

If the retro-active reset feature is activated after
the vehicle is started, but before it begins moving,
the display will show the number of miles (mi)
or kilometers (km) that were driven during the
last ignition cycle.
RANGE
Press the trip/fuel button until RANGE displays.
This display shows the approximate number
of remaining miles (mi) or kilometers (km) the
vehicle can be driven without refueling. The
display will show LOW if the fuel level is low.
The fuel range estimate is based on an average
of the vehicle’s fuel economy over recent
driving history and the amount of fuel remaining
in the fuel tank. This estimate will change if driving
conditions change. For example, if driving in
traffic and making frequent stops, this display
may read one number, but if the vehicle is driven
on a freeway, the number may change even
though the same amount of fuel is in the fuel
tank. This is because different driving conditions
produce different fuel economies. Generally,
freeway driving produces better fuel economy
than city driving. Fuel range cannot be reset.
AVG (Average) ECONOMY
Press the trip/fuel button until AVG ECONOMY
displays. This display shows the approximate
average miles per gallon (mpg) or liters per
100 kilometers (L/100 km). This number is
calculated based on the number of mpg (L/100 km)
recorded since the last time this menu item was
reset. To reset AVG ECONOMY, press and
hold the set/reset button.
TIMER
Press the trip/fuel button until TIMER displays.
This display can be used as a timer.
To start the timer, press the set/reset button while
TIMER is displayed. The display will show the
amount of time that has passed since the timer
was last reset, not including time the ignition is off.
Time will continue to be counted as long as the
ignition is on, even if another display is being shown
on the DIC. The timer will record up to 99 hours,
59 minutes and 59 seconds (99:59:59) after which
the display will return to zero.
To stop the timer, press the set/reset button briey
while TIMER is displayed.
To reset the timer to zero, press and hold the
set/reset button while TIMER is displayed.
238

If your vehicle has DIC buttons, you can use the
trip odometer reset stem to view the following
displays: odometer and trip odometers.
Trip Odometer Reset Stem Menu Items
ODOMETER
Press the trip odometer reset stem until
ODOMETER displays. This display shows the
distance the vehicle has been driven in either
miles (mi) or kilometers (km).
To switch between English and metric
measurements, see “UNITS” later in this section.
TRIP A or TRIP B
Press the trip odometer reset stem until TRIP A
or TRIP B displays. This display shows the
current distance traveled in either miles (mi) or
kilometers (km) since the last reset for each
trip odometer. Both trip odometers can be used
at the same time.
Each trip odometer can be reset to zero separately
by pressing and holding the trip odometer reset
stem while the desired trip odometer is displayed.The trip odometer has a feature called the
retro-active reset. This can be used to set the trip
odometer to the number of miles (kilometers) driven
since the ignition was last turned on. This can be
used if the trip odometer is not reset at the
beginning of the trip.
To use the retro-active reset feature, press and
hold the trip odometer reset stem for at least
four seconds. The trip odometer will display the
number of miles (mi) or kilometers (km) driven
since the ignition was last turned on and the
vehicle was moving. Once the vehicle begins
moving, the trip odometer will accumulate mileage.
For example, if the vehicle was driven 5 miles
(8 km) before it is started again, and then
the retro-active reset feature is activated, the
display will show 5 miles (8 km). As the vehicle
begins moving, the display will then increase
to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
If the retro-active reset feature is activated after
the vehicle is started, but before it begins moving,
the display will show the number of miles (mi)
or kilometers (km) that were driven during the
last ignition cycle.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the
driver that the status of the vehicle has changed
and that some action may be needed by the driver
to correct the condition. Multiple messages may
appear one after another.
Some messages may not require immediate
action, but you can press any of the DIC buttons
on the instrument panel or the trip odometer
reset stem on the instrument panel cluster
to acknowledge that you received the messages
and to clear them from the display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These
messages require action before they can be
cleared. You should take any messages that
appear on the display seriously and remember that
clearing the messages will only make the
messages disappear, not correct the problem.
The following are the possible messages that can
be displayed and some information about them.
ALL WHEEL DRIVE OFF
If your vehicle has the All-Wheel Drive (AWD)
system, this message displays when there
is a compact spare tire on the vehicle, when
the Anti-lock Brake System (ABS) warning light
comes on, or when the rear differential uid
is overheating. This message turns off when the
differential uid cools.
The AWD system is disabled until the compact
spare tire is replaced by a full-size tire. If the
warning message is still on after putting on the
full-size tire, you need to reset the warning
message. To reset the warning message, turn
the ignition off and then back on again after
30 seconds. If the message stays on, see your
dealer/retailer right away. SeeAll-Wheel Drive
(AWD) System on page 339for more information.
AUTOMATIC LIGHT CONTROL OFF
This message displays when the automatic
headlamps are turned off. This message clears
itself after 10 seconds.

CRUISE SET TO XXX
This message displays whenever the cruise control
is set. SeeCruise Control on page 180for more
information.
DRIVER DOOR OPEN
This message displays and a chime sounds if the
driver’s door is not fully closed and the vehicle
is in a drive gear. Stop and turn off the vehicle,
check the door for obstructions, and close the door
again. Check to see if the message still appears
on the DIC.
ENGINE HOT A/C (Air Conditioning) OFF
This message displays when the engine coolant
becomes hotter than the normal operating
temperature. SeeEngine Coolant Temperature
Gage on page 225. To avoid added strain on
a hot engine, the air conditioning compressor
automatically turns off. When the coolant
temperature returns to normal, the air conditioning
compressor turns back on. You can continue to
drive your vehicle.
If this message continues to appear, have the
system repaired by your dealer/retailer as soon
as possible to avoid damage to the engine.
ENGINE OIL LOW ADD OIL
If your vehicle has an oil level sensor, this
message displays if the oil level in the vehicle
is low. Check the oil level and correct it as
necessary. You may need to let the vehicle cool
or warm up and cycle the ignition to be sure
this message clears. SeeEngine Oil on page 397
for additional information.
ENGINE OVERHEATED IDLE ENGINE
Notice:If you drive your vehicle while the
engine is overheating, severe engine damage
may occur. If an overheat warning appears
on the instrument panel cluster and/or
DIC, stop the vehicle as soon as possible.
Do not increase the engine speed above
normal idling speed. SeeEngine Overheating
on page 410for more information.
This message displays when the engine coolant
temperature is too hot. Stop and allow the vehicle
