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.
The ignition should be in the OFF position while the vehicle is being
refueled. When the gauge first indicates empty, there is a small amount
of reserve fuel in the tank. When refueling the vehicle from empty
indication, the amount of fuel that can be added will be less than the
advertised capacity due to the reserve fuel.
The FUEL icon and arrow indicates which side of the vehicle the fuel
filler door is located.
Refer toFilling the tankin theMaintenance and Specifications
chapter for more information.
Battery voltage gauge:Indicates
the battery voltage when the
ignition is in the ON position. If the
pointer moves and stays outside the
normal operating range, have the
vehicle’s electrical system checked
by your authorized dealer as soon as possible.
Engine oil pressure gauge:
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 by your authorized dealer.

vehicle’s operating systems.
In the event of a multiple warning situation, the message center will

•They cannot be cleared until the condition is corrected.
•They will reappear on the display ten minutes from the reset.
•They will not reappear until an ignition OFF-ON cycle has been
completed.
