ignition BUICK LUCERNE 2007 Workshop Manual

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.Fuel Range
Press the trip/fuel button until FUEL RANGE
displays. This display shows the approximate
number of remaining miles (mi) or kilometers (km)
the vehicle can be driven without refueling.
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.
If your vehicle is low on fuel, the FUEL LEVEL
LOW message will be displayed. See “FUEL
LEVEL LOW” underDIC Warnings and Messages
on page 221for more information.
