2009 GMC ACADIA fuel

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

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 may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misring,
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 5-5.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 x 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.

Highbeam On Light
The highbeam on light comes on
when the high-beam headlamps are
in use.
SeeHeadlamp High/Low-Beam
Changer on page 3-7for more
information.
Tow/Haul Mode Light
This light comes on when the
Tow/Haul mode has been activated.
For more information, see
Tow/Haul Mode on page 2-26.
Fuel Gage
When the ignition is on, the fuel
gage shows how much fuel is left
in the tank.
An arrow in the fuel gage indicates
the side of the vehicle the fuel
door is on.
The gage will rst indicate empty
before the vehicle is out of fuel, the
vehicle’s fuel tank should be
lled soon.
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 3-56.Here are some situations that may
occur with the 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 the ignition is turned off.

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”
earlier 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.
Instrument Panel 3-49

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
