Engine oil pressure gauge (if
equipped): Indicates engine oil
pressure. The needle should stay in
the normal operating range
(between "L" and "H"). If the needle
falls below the normal range, stop
the vehicle, turn off the engine and
check the engine oil level. Add oil if
needed. If the oil level is correct,
have your vehicle checked at your
dealership or by a qualified
technician.
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.
• Standard instrument cluster
• Optional instrument cluster
A minimum of four gallons must be
added or removed from the fuel
tank in order for the gauge to
instantaneously update. If less than
four gallons is added, the gauge will
take between five and ten minutes
to update.
Refer to Filling the tank in the
Maintenance and Specifications
chapter for more information.
