CAUTION!
• Damage to the fuel system or emission control
system could result from using an improper fuel
cap (gas cap). A poorly fitting cap could let impu-
rities into the fuel system. Also, a poorly fitting
aftermarket cap can cause the “Malfunction Indi-
cator Light (MIL)” to illuminate, due to fuel vapors
escaping from the system.
• A poorly fitting gas cap may cause the MIL to turn on.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
