Driving 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 When the engine starts, the idle RPM runs faster to warm the engine. If the engine idle speed does not slow down automatically, have the vehicle checked. If your 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 the snow and/or ice away from the air induction inlet. The following starting instructions are for vehicles equipped with a gasoline engine; if your vehicle is equipped with a Diesel engine, refer to Starting the engine in your 6.0 and 6.4 Liter Power Stroke Direct Injection Turbo Diesel Owner's Guide Supplement. Before starting the vehicle: 1. Make sure all occupants buckle 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 electrical accessories are off. If starting a vehicle with an automatic transmission: 1. Make sure the parking brake is set. 2. Make sure the gearshift is in P (Park). 256 2008 F-250/350/450/550 (f23) Owners Guide (post-2002-fmt) USA (fus)
