What Is ABS?
ABS is an electronic control system that improves vehicle stability and steerability
by preventing wheel lock during braking.
How Does ABS Work?
The ABS system monitors wheel rotation, and if it detects any wheel locking up,
the system automatically reduces the brake pressure at that wheel. If necessary,
the ABS system automatically modulates braking forces at one or more of the
wheel ends. The system maintains lateral stability by preventing wheel lock
during braking.
What is the optional ABS Off-Road Mode?
This is an optional ABS feature operated by a dash-mounted switch for use
when operating your vehicle “off-road” on soft surfaces. Below 25 mph, this
feature improves ABS performance under off-road operating conditions. If
your vehicle is equipped with this feature, toggle the switch to the “ABS off-
road” position when operating on soft surfaces. Always remember to turn the
ABS off-road feature off when driving on a firm road surface. A new ignition
cycle, or a second depression of the Off-road switch, will turn this function off
and restore normal ABS functionality and (if installed) full RSP functionality.
For more details on optional ATC and RSP features, see pages 6 and 7 of this
manual.
WARNING! The ABS Off-Road mode should not be used on normal,
paved road surfaces because vehicle stability and steerability may
be reduced. The ABS indicator lamp will flash slowly to indicate to the driver
that the ABS off-road mode is engaged.
CAUTION: When the ABS Off-Road mode is engaged, stability functions are
disabled at speeds below 25 mph. The ATC/RSP Indicator lamp will illuminate
to indicate that the RSP stability system function is disabled.
