FORD 2008 E-450 v.3 - Manual (Page 170)

If a system fault is detected, the traction control active light will
illuminate, the Traction Control™ button will not turn the system on or
off and your vehicle should be serviced by an authorized dealer.
ADVANCETRAC
ா WITH ROLL STABILITY CONTROL™ (RSC)
STABILITY ENHANCEMENT SYSTEM (IF EQUIPPED)
The AdvanceTrac
௡ with RSC system provides stability and traction
enhancement for certain driving situations when driver assistance is
needed. It helps your vehicle maintain traction, when driving on slippery
and/or hilly road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled by momentarily reducing engine
power and rapidly applying the anti-lock brakes. The system is a driver
aid which makes your vehicle easier to handle primarily on snow and
ice-covered roads.
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTrac
௡ with RSC system off by pressing the AdvanceTrac௡
with RSC button. This will allow your tires to “dig” for traction.
Remember to switch the AdvanceTrac
௡ with RSC system back on once
the vehicle is no longer stuck.
If the AdvanceTrac
௡ with RSC system is activated excessively in a short
period of time, the brake portion of the system will shut down to allow
the brakes to cool down. A limited AdvanceTrac
௡ with RSC function
using only engine power reduction will still help control the wheels from
over-spinning. When the brakes have cooled down, the system will again
function normally. Anti-lock braking is not affected by this condition and
will function normally during the cool-down period.
The AdvanceTrac
௡ with RSC system enhances your vehicle’s stability
during maneuvers that require all available tire traction, like in
wet/snowy/icy road conditions and/or when performing emergency
maneuvers. In an emergency lane-change, the driver will experience
better overall vehicle traction, and have better control of the vehicle.
The AdvanceTrac
௡ with RSC system helps the driver maintain steering
control if the vehicle begins to slide excessively left or right or spin out.
AdvanceTrac
௡ with RSC will attempt to correct the sliding motion by
applying brake force at individual tires and, if necessary, by reducing
engine power.
