2000 CADILLAC DEVILLE MPG

2-86
If the fuel supply gets down to approximately three
gallons (11.4 L) of fuel remaining in the tank, the
FUEL LEVEL LOW message will appear on the Driver
Information Center (DIC).
On the digital cluster, if the fuel is less than
approximately 1.2 gallons (4.7 L) the ªEº segment on
the gage will flash.
Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and do
not indicate that anything is wrong with the fuel gage:

At the gas station the gas pump shuts off before the
gage reads full.

GAL FUEL USED on the Driver Information Center
does not correspond exactly to the amount of fuel
remaining as shown on the fuel gage.

The gage may change when you turn, stop or
speed up.Fuel Data Display (Digital Cluster)
The fuel data display tells
you all you about the fuel
economy and how far
you can travel with the
fuel remaining.
The average fuel economy (AVG) display shows the
average miles per gallon.
To reset the average fuel economy, press the INFO
button until the MPG AVG is displayed on the Driver
Information Center (DIC). Press and hold the INFO
RESET button until both the fuel data display and
DIC display reads 0.0.

The RANGE display shows how far the computer thinks
you can travel with the fuel that is in the tank. The
computer does not know what driving conditions will be
like for the rest of your trip, so the range is estimated
based on the recent fuel economy. Therefore, the range
reading may change as your driving habits change.
Going from city to highway driving may increase the
range reading.
If the range display shows LO, you should stop for fuel
as soon as possible.
On the analog cluster, fuel data can be obtained by
pressing the INFO button. See ªDriver Information
Centerº in the Index.
