PRECAUTIONS WHEN STARTING AND DRIVING WARNING ● 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 leave children or adults who would normally require the support of others in your vehicle. Unattended pets should not be left alone either. ● Properly secure all cargo with ropes or straps to help prevent it from sliding or shifting. Do not place cargo higher than the seatbacks. In a sudden stop or collision, unsecured cargo could cause personal injury. ● Do not run the engine in closed spaces such as a garage. ● Do not park the vehicle with the engine running for any extended length of time. ● Keep the back door and rear vent windows closed while driving, otherwise exhaust gases could be drawn into the passenger compartment. If you must drive with the back door or rear vent windows open, follow these precautions: 1. Open all the windows. 2. Set the air recirculation button to off and the fan control dial to high to circulate the air. ● If electrical wiring or other cable connections must pass to a trailer through the seal on the back door or the body, follow the manufacturer's recommendation to prevent carbon monoxide entry into the vehicle. ● 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 three-way catalyst are burned at high temperatures to help reduce pollutants. EXHAUST GAS (carbon monoxide) WARNING ● Do not breathe exhaust gases; they contain colorless and odorless carbon monoxide. Carbon monoxide is dangerous. It 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. WARNING ● The exhaust gas and the exhaust system are very hot. Keep people, animals or flammable materials away from the exhaust system components. ● 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. 5-2 Starting and driving
