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. Guarding Against Exhaust Fumes Carbon monoxide, although colorless and odorless, is present in exhaust fumes. Take precautions to avoid its dangerous effects. RWARNING If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. If your vehicle has rear windows and doors that were installed as part of a van conversion, close them while it is running. This prevents exhaust fumes from being drawn into the passenger compartment. 71
