166 STARTING AND OPERATING Materials Added to Fuel All gasoline sold in the United States is required to contain effective detergent additives. Use of additional detergents or other additives is not needed under normal conditions and would result in unnecessary cost. Therefore, you should not have to add anything to the fuel. Sulfur in Gasoline If you live in the Northeast United States, your vehicle may have been designed to meet California low emission standards with cleaner burning California reformulated gasoline with low sulfur. If such fuels are not available in states adopting California emission standards, your vehicle will operate satisfactorily on fuels meeting Federal specifications, but emission control system performance may be adversely affected. Gasoline sold outside of California is permitted to have higher sulfur levels, which may affect the performance of the vehicle's catalytic converter. This may cause the CHECK ENGINE light to illuminate. DaimlerChrysler Corporation recommends that you try a different brand of unleaded gasoline having lower sulfur to determine if the problem is fuel-related prior to returning your vehicle to an authorized dealer for service. CAUTION! If the CHECK ENGINE Light is flashing, immediate service is required. See the Onboard Diagnostic System (OBDII) paragraph in the Maintaining Your Vehicle section of this manual. ADDING FUEL Fuel Filler Cap (Gas Cap) The gas cap is located under the fuel filler door, on the passenger's side of the vehicle. To open the door, be sure it is unlocked, then gently press the rear edge of the door until a click can be heard, then release. The door rear edge will spring open enough to grasp and pull it completely open. If the central locking system does not release the fuel filler door, see your authorized dealer for service. If the gas cap is lost or damaged, be sure the replacement cap has been designed for use with this vehicle.
