ignition BUICK LUCERNE 2008 Service Manual

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 ignition 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 5-8. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missingfuel cap allows fuel to evaporate into the atmosphere. A
few driving trips with the cap properly installed should
turn the light off.
Did you just drive through a deep puddle of water?
If so, your 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.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-6. Poor fuel quality causes
the engine not to run as efficiently as designed. You
might notice this as stalling after start-up, stalling when
you put the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration — these
conditions might go away once the engine is warmed up.
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer/retailer can check the vehicle. Your
dealer/retailer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that might have developed.

Fuel Gage
The fuel gage shows about how much fuel is in your
tank. It works only when the ignition is on. When
the indicator moves to the edge of the low fuel warning
band, the low fuel warning light will come on and a
chime will sound. You still have a little fuel left, but you
need to get more fuel right away.Here are some things that some owners ask about.
None of these show a problem with your fuel gage:
At the service station, the gas pump shuts off before
the gage reads full.
It takes more (or less) fuel to ll up than the gage
indicated. For example, the gage may have
indicated half full, but it took more (or less) than
half the tank’s capacity to ll it.
The gage moves up a little when you turn a corner,
speed up or make a hard stop.
The gage does not go back to empty when you turn
off the ignition.
Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located
below the speedometer in the instrument panel cluster.
The DIC buttons are located on the instrument panel,
to the left 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. United States

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).
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.
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.
