Driving WARNING: Do not park, idle, or drive your vehicle in dry grass or other dry ground cover. The emission system heats up the engine compartment and exhaust system, which can start a fire. WARNING: 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. See Guarding against exhaust fumes in this chapter for more instructions. WARNING: If you smell exhaust fumes inside your vehicle, have your dealer inspect your vehicle immediately. Do not drive if you smell exhaust fumes. Important safety precautions A computer system controls the engine's idle revolutions per minute (RPM). When the engine starts, the idle RPM runs higher than normal in order to warm the engine. If the engine idle speed does not slow down automatically, have the vehicle checked. If the vehicle is operated in a heavy snow storm or blowing snow conditions, the engine air induction may become partially clogged with snow and/or ice. If this occurs the engine may experience a significant reduction in power output. At the earliest opportunity, clear all snow and/or ice away from the air induction inlet. Do not allow the vehicle to idle for more than 10 minutes at the higher engine RPM. Before starting the vehicle: 1. Make sure all vehicle occupants have buckled their safety belts. For more information on safety belts and their proper usage, refer to the Seating and Safety Restraints chapter. 2. Make sure the headlamps and vehicle accessories are off. 279 2011 F-150 (f12) Owners Guide, 3rd Printing USA (fus)
