FORD 2007 Expedition v.1 - Manual (Page 233)

The AdvanceTrac
௡ with RSC stability enhancement system can be turned
off manually by pressing the AdvanceTrac
௡ with RSC button (refer to
AdvanceTrac
௡ with Roll Stability Control (RSC) Stability Enhancement
System in this chapter) while operating in 2H, 4A or 4H while driving in
deep sand, very deep snow or more strenuous off-road maneuvers. This
will disable the engine management feature, allowing the vehicle to
maintain full power and enhanced momentum through the obstacle.
How your vehicle differs from other vehicles
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
Maintain steering wheel control at all times, especially in rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. To maintain
steering and braking control of your vehicle, you must have all four
wheels on the ground and they must be rolling, not sliding or spinning.
Basic operating principles
• Do not use 4H (4x4) or 4L (4x4 LOW) on dry, hard surfaced roads.
This may damage the driveline and axles.
• Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on pavement made slippery by
loose sand, water, gravel, snow or ice.
If your vehicle goes off the edge of the pavement
• If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application. Ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
• It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
