300 STARTING AND OPERATING
ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is located on the passenger side of the
vehicle. If the gas cap is lost or damaged, be sure the
replacement cap is the correct one for this vehicle.
Fuel Filler Cap
CAUTION!
• Damage to the fuel system or emission control
system could result from using an improper fuel
filler cap. A poorly fitting cap could let impurities
into the fuel system. Also, a poorly fitting aftermar-
ket cap can cause the "Malfunction Indicator Light
(MIL)" to illuminate, due to fuel vapors escaping
from the system.
• To avoid fuel spillage and overfilling, do not "top
off" the fuel tank after filling.
