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 other enclosed area. Never sit in a stopped vehicle for more than a short period of time with the engine running. Exhaust fumes are toxic. See Guarding Against Exhaust Fumes in this chapter for more instructions. RWARNING If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. Make sure your Bronco's tailgate window is closed when your truck is running to prevent exhaust fumes from being drawn in. If you must have the tailgate window open, adjust your air control system to force outside air into the front of your truck. If your Bronco has outside air control vents, open them fully. Have the exhaust and body ventilation systems checked whenever: u your vehicle is raised for service u the sound of the exhaust system changes u your vehicle has been damaged in a collision Improve your ventilation by keeping all air inlet vents clear of snow, leaves, and other debris. 71
