2009 BUICK ENCLAVE fuel

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.
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 systems could 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. See
Accessories 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.
Instrument Panel 3-37

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.
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.

Cruise Control Light
This light comes on whenever the
cruise control is set.
The light goes out when the cruise
control is turned off. SeeCruise
Control on page 3-10for more
information.
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 about how much fuel
the vehicle has left in the fuel tank.
An arrow on 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, but
the vehicle’s fuel tank should be
lled soon.
When the fuel tank is low on fuel,
the FUEL LEVEL LOW message
appears on the Driver Information
Center (DIC). For more information
seeDIC Warnings and Messages
on page 3-48.
Here are some situations that can
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.

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).
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.
3-44 Instrument Panel

Each trip odometer can be reset to
zero separately by pressing the
set/reset button 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.
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 frequentstops, 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.

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.FUEL USED
Press the trip/fuel button until FUEL
USED displays. This display
shows the number of gallons (gal)
or liters (L) of fuel used since
the last reset of this menu item. To
reset the fuel used information,
press and hold the set/reset button
while FUEL USED is displayed.
AVG (Average) SPEED
Press the trip/fuel button until AVG
SPEED displays. This display
shows the average speed of the
vehicle in miles per hour (mph) or
kilometers per hour (km/h). This
average is calculated based on the
various vehicle speeds recorded
since the last reset of this value. To
reset the value to zero, press
and hold the set/reset button.
Blank Display
This display shows no information.DIC Compass
Your vehicle may have a compass
in the Driver Information
Center (DIC).
Compass Zone
The zone is set to zone eight upon
leaving the factory. Your dealer/
retailer will set the correct zone for
your location.
Under certain circumstances,
such as during a long distance
cross-country trip or moving
to a new state or province, it will be
necessary to compensate for
compass variance by resetting the
zone through the DIC if the zone
is not set correctly.
Compass variance is the difference
between the earth’s magnetic
north and true geographic north. If
the compass is not set to the
zone where you live, the compass
may give false readings. The
compass must be set to the variance
zone in which the vehicle is
traveling.
