Starting Guarding Against Exhaust Fumes Carbon monoxide, although colorless and odorless, is present in exhaust fumes. Take precautions to avoid its dangerous effects. RWARNING Do not start your vehicle in a closed garage or in other enclosed areas. Exhaust fumes can be toxic. Always open the garage door before you start the engine. RWARNING If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. Have the exhaust and body ventilation systems checked whenever: s your vehicle is raised for service s the sound of the exhaust system changes s your vehicle has been damaged in a collision Improve your ventilation by keeping all air inlet vents clear of snow, leaves, and other debris. If the engine is idling while you are stopped in an open area for long periods of time, open the windows at least one inch (2.5 cm). Also, adjust the heating or air conditioning system to bring in outside air. If you use the heater, set the fan speed on medium or high with the function control knob turned to FLR, PNL/FLR or PANEL. If you use the air conditioner, set the fan speed on medium or high with the A/C button pressed. (Do not use MAX A/C.) 123
