Starting and operating " You will see the " " sign in the combination meter. This indicates that the fuel filler door (lid) is located on the right side of the vehicle. " If the fuel filler cap is not tightened until it clicks or if the tether is caught under the cap, the CHECK ENGINE warning light may come on. Refer to the "Warning and indicator lights" section located in chapter 3. (Turbo model only) Promptly put fuel in the tank whenever the low fuel warning light comes on. If the engine misfired as a result of an empty tank, resulting catalyzer damage could cause damage to the turbocharger. If you use the wrong cap, it may not fit or have proper venting, and your fuel tank and emission control system might be damaged. " Never add any cleaning agents to the fuel tank. The addition of a cleaning agent may cause damage to the fuel system. " Make sure that the cap is tightened until it clicks to prevent fuel spillage in the event of an accident. " Do not let fuel spill on the exterior surfaces of the vehicle. Fuels may cause paint damage, which is not covered under the SUBARU Limited Warranty. " Always use a genuine SUBARU fuel filler cap. - CONTINUED - 7-7
