PRECAUTIONS WHEN STARTING AND DRIVING WARNING Do not leave children, unreliable adults, or pets alone in your vehicle. They could accidentally injure themselves or others through inadvertent operation of the vehicle. Also, on hot, sunny days, temperatures in a closed vehicle could quickly become high enough to cause severe or possibly fatal injuries to people or animals. ● Do not park the vehicle with the engine running for any extended length of time. ● If a special body, camper, or other equipment is added for recreational or other usage, follow the manufacturer's recommendation to prevent carbon monoxide entry into the vehicle. Do not occupy these areas while the engine is running even if the vehicle is parked. (Some recreational vehicle appliances such as stoves, refrigerators, heaters, etc. may also generate carbon monoxide.) ● The exhaust system and body should be inspected by a qualified mechanic whenever: a. The vehicle is raised for service. b. You suspect that exhaust fumes are entering into the passenger compartment. c. You notice a change in the sound of the exhaust system. d. You have had an accident involving damage to the exhaust system, underbody, or rear of the vehicle. THREE-WAY CATALYST The three-way catalyst is an emission control device installed in the exhaust system. Exhaust gases in the converter are burned at high temperatures to help reduce pollutants. WARNING ● The exhaust gas and the exhaust system are very hot. Keep people or flammable materials away from the exhaust pipe. ● Do not stop or park the vehicle over flammable materials such as dry grass, waste paper or rags. They may ignite and cause a fire. CAUTION ● Do not use leaded gasoline. Deposits from leaded gasoline will seriously reduce the three-way catalyst's ability to help reduce exhaust pollutants. ● Keep your engine tuned up. Malfunctions in the ignition, fuel injection, or electrical systems can cause overrich fuel flow into the converter, causing it to overheat. Do not keep EXHAUST GAS (carbon monoxide) WARNING Do not breathe exhaust gases; they contain colorless and odorless carbon monoxide. Carbon monoxide is a dangerous gas, and can cause unconsciousness or death. ● If you suspect that exhaust fumes are entering the vehicle, drive with all windows fully open, and have the vehicle inspected immediately. ● Do not run the engine in closed spaces such as a garage. 5-2 Starting and driving
