2009 GMC ACADIA stop start

Tire Pressure Light
The tire pressure light should come
on briey as the engine is started.
If it does not, have the vehicle
service by your dealer/retailer.
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 signicantly
underinated.
A tire pressure message in the
Driver Information Center (DIC),
may accompany the light.SeeDIC Warnings and Messages
on page 3-56for more information.
Stop and check the tires as
soon as it is safe to do so.
If underinated, inate to the
proper pressure. SeeTires on
page 5-35for 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 ashes
for about a minute and stays
on steady for the remainder of the
ignition cycle. This sequence
will repeat with every ignition cycle.
SeeTire Pressure Monitor System
on page 5-42for 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 comes 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.
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.
Instrument Panel 3-41

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 systemscould 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.
SeeAccessories and
Modifications on page 5-3.
This light comes 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 the vehicle. Diagnosis
and service might be required.
The following can 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 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 is still
ashing, follow the previous steps
and see your dealer/retailer for
service as soon as possible.
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:
Make sure the fuel cap is fully
installed. SeeFilling the Tank
on page 5-7. 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.
3-42 Instrument Panel

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.
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

30 seconds for a DVD to begin
playing).
If the ignition or radio is turned off,
while a CD is in the player, it stays in
the player. When the ignition or radio
is turned on, the CD starts playing
where it stopped, if it was the last
selected audio source. The CD is
controlled by the buttons on the
radio faceplate or by the RSA unit.
SeeRear Seat Audio (RSA) on
page 3-118for more information.
The DVD/CD decks, (upper slot is
the DVD deck and the lower slot is
the CD deck) of the radio are
compatible with most audio CDs,
CD-R, CD-RW, and MP3/WMAs.
When a CD is inserted, the text label
DVD or CD symbol displays on
the left side of the radio display.
As each new track starts to play,
the track number displays.Care of CDs and DVDs
If playing a CD-R, the sound quality
can be reduced due to CD-R or
CD-RW quality, the method
of recording, the quality of the music
that has been recorded, and the
way the CD-R or CD-RW has been
handled. Handle them carefully.
Store CD-R(s) or CD-RW(s) in their
original cases or other protective
cases and away from direct sunlight
and dust. The CD or DVD player
scans the bottom surface of the disc.
If the surface of a CD is damaged,
such as cracked, broken, or
scratched, the CD does not play
properly or not at all. Do not touch
the bottom side of a CD while
handling it; this could damage the
surface. Pick up CDs by grasping
the outer edges or the edge of
the hole and the outer edge.
If the surface of a CD is soiled, take
a soft, lint free cloth or dampen a
clean, soft cloth in a mild, neutral
detergent solution mixed with water,and clean it. Make sure the wiping
process starts from the center
to the edge.
Care of the CD and DVD Player
Do not add any label to a CD, it could
get caught in the CD or DVD player.
If a CD is recorded on a personal
computer and a description label is
needed, try labeling the top of the
recorded CD with a marking pen.
The use of CD lens cleaners for
CDs is not advised, due to the risk
of contaminating the lens of the
CD optics with lubricants internal to
the CD and DVD player mechanism.
Notice:If a label is added to
a CD, or more than one CD is
inserted into the slot at a time,
or an attempt is made to play
scratched or damaged CDs, the
CD player could be damaged.
While using the CD player, use
only CDs in good condition
without any label, load one CD at a
time, and keep the CD player and
the loading slot free of foreign
materials, liquids, and debris.
