2009 BUICK LACROSSE ECO mode

Fuel Menu Items (Uplevel Only)
.
(Fuel):Press this button to scroll through the
following menu items:
Fuel Range
Press the fuel button until FUEL RANGE displays.
This mode shows the approximate number of remaining
miles or kilometers the vehicle can be driven without
refueling.
Fuel range is based on several factors, including
distance traveled, fuel used, fuel capacity, etc.
This estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, this mode 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.
If your vehicle is low on fuel, FUEL RANGE LOW will
display followed by the LOW FUEL message. See “LOW
FUEL” underDIC Warnings and Messages on page 3-56
for more information.
Average Fuel Economy
Press the fuel button until AVG ECONOMY displays.
This mode 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. The display will return to zero.
Gages Menu Items (Uplevel Only)
2
(Gages):Press this button to scroll through the
following menu items:
Battery
Press the gages button until BATTERY displays.
This mode shows the current battery voltage.
Your vehicle’s charging system regulates voltage based
on the state of the battery. The battery voltage may
uctuate when viewing this information on the DIC.
This is normal.
If there is a problem with the battery charging system,
a DIC message will display. SeeDIC Warnings and
Messages on page 3-56for more information.
SeeElectric Power Management on page 3-18for more
information.

Oil Life
Press the gages button until OIL LIFE displays. This
mode shows an estimate of the oil’s remaining useful
life. If you see OIL LIFE 99% on the display, that means
99% of the current oil life remains. The engine oil life
system will alert you to change your oil on a schedule
consistent with your driving conditions.
When the remaining oil life is low, the CHANGE OIL
SOON message will appear on the display. You should
change your oil as soon as possible. SeeEngine Oil
on page 5-15. In addition to the engine oil life system
monitoring the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4
for more information.
Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be careful not
to reset the OIL LIFE accidentally at any time other than
when the oil has just been changed. It cannot be reset
accurately until the next oil change. To reset the engine
oil life system, seeEngine Oil Life System on page 5-18.
The display will show 100% when the system is reset.
Tire Pressure
On vehicles with the Tire Pressure Monitor System
(TPMS), press the gages button until FRONT TIRE
PRESSURE displays. This mode shows the pressure
for the front tires. To view the pressure for the rear
tires, press the gages button again until REAR TIRE
PRESSURE displays. The tire pressure will be shown in
either pounds per square inch (psi) or kilopascals (kPa).
If a low tire pressure condition is detected by the
system while driving, a message advising you to check
the pressure in a specic tire will appear in the display.
SeeInflation - Tire Pressure on page 5-61andDIC
Warnings and Messages on page 3-56for more
information.
If the tire pressure display shows dashes or blanks
instead of a value, there may be a problem with
your vehicle. If this consistently occurs, see your
dealer/retailer for service.

DIC Warnings and Messages
Messages are displayed on the uplevel DIC to notify the
driver that the status of the vehicle has changed and that
some action may be needed by the driver to correct the

another.
Some messages may not require immediate action,
but you can press any of the uplevel DIC buttons to
acknowledge that you received the message and
clear it from the DIC display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These messages
require action before they can be cleared.

messages will only make the messages disappear,
not correct the problem.
The following are the possible messages that can be
displayed and some information about them.
