200 STARTING AND OPERATING FUEL FILLER CAP (GAS CAP) The fuel cap is located on the left side of the vehicle. If the fuel cap is lost or damaged, be sure the replacement cap is for use with this vehicle. 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 impurities into the fuel system. Also, a poorly fitting aftermarket cap can cause the MIL (Malfunction Indicator Light) to illuminate, due to fuel vapors escaping from the system. • Turn the engine off. • Rotate the fuel cap to the left to remove. • To replace the cap, insert it into the filler neck and tighten the cap about 1/4 turn until you hear one click. This is an indication that the cap is properly tightened. • Make sure that the fuel cap tether strap is not caught under the fuel cap.
