FORD 2011 Explorer v.3 - Manual (Page 265)

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
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 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 for the air induction inlet.
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.
• Make sure the parking brake is
set.
