Here are five things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage.
D
At the gas station, the gas pump shuts off before
the gage reads F (full).
D
It takes more (or less) fuel to fill up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank's capacity
to fit it.
D
The gage pointer may move while cornering,
braking or speeding up.
D
The gage may not indicate E (empty) when the
ignition is turned off.
D
The gage reading may change slightly within the
first several minutes after starting the vehicle.
You can use the Driver Information Center (DIC) to
display more detailed fuel information. Each time you
press FUEL, one of the following will appear in the
Driver Information Center (DIC).
D
AVERAGE: The fuel economy calculated for
the current tank of fuel, or since you last reset
the display.
D
INST (Instant): The fuel economy calculated
for your current driving conditions.
D
RANGE: The distance you can drive
before refueling.
D
BLANK: The fuel gage is displayed alone.
You should reset the fuel information display every
time you refuel. To reset the display, press FUEL
until AVERAGE appears. Then, press RESET on the
Driver Information Center (DIC).
