Speedometer and Odometer
The speedometer shows the vehicle speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far the vehicle has been
driven, in either miles or kilometers.
This vehicle has a tamper resistant odometer.
If the vehicle needs a new odometer installed, the new
one can be set to the mileage total of the old odometer.
If this is not possible, it is set to zero and a label must
be put on the driver's door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
A trip odometer show how far the vehicle has been
driven since the odometer was last set to zero. See
Driver Information Center (DIC)
on page 4‑42for
information on resetting the trip odometer.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Safety Belt Reminders
Driver Safety Belt Reminder Light
When the engine is started, a chime sounds for several
seconds to remind a driver to fasten the safety belt,
unless the driver safety belt is already buckled.
The safety belt light
comes on and stays on
for several seconds, then
flashes for several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver
safety belt is already buckled, neither the chime nor the
light comes on.

DIC Buttons
The buttons are the trip/fuel, vehicle information,
customization, and set/reset buttons. The button
functions are detailed in the following pages.
3(Trip/Fuel):Press this button to display the
odometer, trip odometers, fuel range, average economy,
instantaneous economy, and average speed.
T(Vehicle Information): Press this button to display
the oil life, units, park assist on vehicles with this
feature, side blind zone alert on vehicles with this
feature, tire pressure readings on vehicles with this
feature, and compass zone and compass calibration on
vehicles with this feature.
U(Customization): Press this button to customize the
feature settings on your vehicle. See DIC Vehicle
Customization
on page 4‑58for more information.
V(Set/Reset): Press this button to set or reset certain
functions and to turn off or acknowledge messages on
the DIC.
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.

ENGINE POWER IS REDUCED
This message displays when the vehicle's engine
power is reduced. Reduced engine power can affect the
vehicle's ability to accelerate. If this message is on, but
there is no reduction in performance, proceed to your
destination. The performance may be reduced the next
time the vehicle is driven. The vehicle may be driven
at a reduced speed while this message is on, but
acceleration and speed may be reduced. Anytime this
message stays on, the vehicle should be taken to your
dealer for service as soon as possible.
ERROR
This message displays while viewing the odometer or
trip odometers if there is a problem with the instrument
panel cluster. See your dealer for service.
FUEL LEVEL LOW
This message displays when your vehicle is low on
fuel. Refill the fuel tank as soon as possible. See
Fuel Gauge
on page 4‑41andFilling the Tankon
page 6‑9for more information.
HOOD OPEN
If your vehicle has the remote start feature, this
message displays when the hood is not closed properly.
Make sure that the hood is closed completely. See
Hood Release on page 6‑13.
ICE POSSIBLE DRIVE WITH CARE
This message displays when the outside air
temperature is cold enough to create icy road
conditions. Adjust your driving accordingly.
LANE DEPARTURE SYSTEM
UNAVAILABLE
If your vehicle has the Lane Departure Warning (LDW)
system, this message may display if the LDW system
does not activate due to a temporary condition. See
Lane Departure Warning (LDW)
on page 3‑40for more
information.
LEFT REAR DOOR OPEN
This message displays when the driver side rear door is
not closed properly. Make sure that the door is closed
completely.
OIL LEVEL LOW ADD OIL
On some vehicles, this message displays when the
vehicle's engine oil is low. Fill the oil to the proper
level as soon as possible. See Engine Compartment
Overview
on page 6‑14for the engine oil fill location.
Also, see Engine Oilon page 6‑18for information on
the kind of oil to use and the proper oil level.

Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset, and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts,
wheel nuts, or Tire Pressure Monitor System (TPMS)
sensors, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts, wheel nuts, and TPMS sensors
for your vehicle.
{WARNING:
Using the wrong replacement wheels, wheel bolts,
or wheel nuts can be dangerous. It could affect
the braking and handling of the vehicle. Tires can
lose air, and cause loss of control, causing a
crash. Always use the correct wheel, wheel bolts,
and wheel nuts for replacement.Notice:
The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
See Changing a Flat Tire
on page 6‑88for more
information.
Used Replacement Wheels
{WARNING:
Replacing a wheel with a used one is dangerous.
How it has been used or how far it has been
driven may be unknown. It could fail suddenly and
cause a crash. When replacing wheels, use a new
GM original equipment wheel.
