Instrument Cluster
Fuel gauge: Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
Proper gauge indication requires the
ignition to be in the OFF or
ACCESSORY position during refueling, otherwise correct fuel indication
after refueling can be slow to update. Also, a minimum of 3 gallons is
needed for correct indication after refueling.
The arrow near the fuel pump icon indicates which side of the vehicle
the fuel filler door is located.
Refer to Filling the tank in the Maintenance and Specifications
chapter for more information.
