Tire Pressure Light
For vehicles with a Tire
Pressure Monitoring
System, this light comes
on briefly when the engine
is started. 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 is
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC)
on page 4‑42for more
information. Stop and check the tires as soon as it is
safe to do so. If underinflated, inflate to the proper
pressure. See Inflation - Tire Pressure
on page 6‑64for 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 flashes for about a
minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. SeeTire Pressure Monitor Operation
on
page 6‑66for more information.
Malfunction Indicator Lamp
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 should come 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.
If the Malfunction Indicator Lamp comes on and stays
on, while the engine is running, this indicates that there
is an OBD II problem and service is required.

.Make sure the electrical system is not wet. The
system could be wet if the vehicle was driven
through a deep puddle of water.
.Make sure to fuel the vehicle with quality fuel.
Poor fuel quality causes the engine not to run as
efficiently as designed and can cause: stalling
after start-up, stalling when the vehicle is changed
into gear, misfiring, 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 6‑6.
If none of the above have made the light turn off,
your dealer can check the vehicle. The dealer has the
proper test equipment and diagnostic tools to fix any
mechanical or electrical problems that might have
developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments may have
programs to inspect the on-vehicle emission control
equipment For the inspection, the emission system test
equipment is connected to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument panel to the left of the
steering wheel. See your dealer if assistance is needed.
The vehicle may not pass inspection if:
.the Malfunction Indicator Lamp is on with the
engine running, or if the light does not come on
when the ignition is turned to ON/RUN while the
engine is off.
.the critical emission control systems have not been
completely diagnosed by the system. This can
happen if the battery has recently been replaced or
if the battery has run down. The diagnostic system
evaluates 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, your
dealer can prepare the vehicle for inspection.

Cruise Control Light
The cruise control light
comes on whenever the
cruise control is set.
The light goes out when the cruise control is turned off.
See Cruise Control
on page 4‑7for more information.
Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
See Headlamp High/Low-Beam Changer
on page 4‑5for more information.
Fuel Gauge
EnglishMetric
The fuel gauge shows about how much fuel is in
the tank.
An arrow on the fuel gauge indicates the side of the
vehicle the fuel door is on.
The gauge 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 comes on and a chime
sounds. The vehicle still has a little fuel left, but the
vehicles fuel tank should be filled soon.
4-41

Black plate (42,1)Buick Lucerne Owner Manual - 2011
Here are some things that some owners ask about.
None of these show a problem with the fuel gauge:
.At the service station, the gas pump shuts off
before the gauge reads full.
.It takes more (or less) fuel to fill up than the gauge
indicated. For example, the gauge may have
indicated half full, but it took more (or less) than
half the tank's capacity to fill it.
.The gauge moves up a little while turning a corner,
speeding up or making a hard stop.
.The gauge does not go back to empty when the
ignition is turned off.
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.The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system
problem is detected. The bottom line of the DIC
shows the shift lever position indicator. See
Automatic
Transmission Operation
on page 3‑24for more
information.
If your vehicle's DIC has these features, the compass
direction and the outside air temperature may also
display on the DIC when viewing the trip and fuel
information. The compass direction appears on the
top right corner of the DIC display. The outside air
temperature automatically appears in the bottom right
corner of the DIC display. If there is a problem with
the system that controls the temperature display, the
numbers will be replaced with dashes. If this occurs,
have the vehicle serviced by your dealer.
The DIC also allows some features to be customized.
See DIC Vehicle Customization
on page 4‑58for more
information.
DIC Operation and Displays
The DIC has different displays which can be accessed
by pressing the DIC buttons located on the instrument
panel, to the left of the instrument panel cluster.

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 kilometers (km) or miles (mi).
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 kilometers (km) or miles (mi) 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 kilometers (miles) 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.
4-43

Black plate (44,1)Buick Lucerne Owner Manual - 2011
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 kilometers (km) or
miles (mi) 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 8 km (5 miles) before
it is started again, and then the retro-active reset feature
is activated, the display will show 8 km (5 miles). As the
vehicle begins moving, the display will then increase to
8.2 km (5.1 miles), 8.4 km (5.2 miles), 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 kilometers (km) or
miles (mi) 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 kilometers (km) or miles (mi) 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”
under DIC Warnings and Messages
on page 4‑49for
more information.
Average Economy
Press the trip/fuel button until AVG ECONOMY
displays. This display shows the approximate average
liters per 100 kilometers (L/100 km) or miles per gallon
(mpg). This number is calculated based on the number
of L/100 km (mpg) recorded since the last time this
menu item was reset. To reset AVG ECONOMY, press
and hold the set/reset button. The display will return
to zero.
Instantaneous Economy
Press the trip/fuel button until INST ECONOMY
displays. This display shows the current fuel economy
at a particular moment and will change frequently as
driving conditions change. This display shows the
instantaneous fuel economy in liters per 100 kilometers
(L/100 km) or miles per gallon (mpg). Unlike average
economy, this screen cannot be reset.
