ESP
®
trailer stabilization
If the trailer you are towing should begin to
sway, the rig can only be stabilized by
immediately applying the brakes hard.
Steering during this maneuver will not help to
stabilize the rig.
The ESP
®
will assist you in such situations.
The ESP
®
recognizes when the trailer starts
swaying and will apply the brakes to reduce
the vehicle speed to a non-critical speed that
allows the vehicle-trailer combination to
stabilize.
