Trailer sway control
Your vehicle may be equipped with trailer sway control. When properly
equipped, trailer sway control will use the vehicle’s AdvanceTrac
௡ with
RSC
௡ system to detect and help reduce trailer sway by applying brake
force at individual wheels and, if necessary, by reducing engine power.
WARNING: Trailer sway control does not prevent a trailer from
swaying, it mitigates the sway from increasing once it has
occurred. If you are experiencing trailer sway it is likely that the trailer
is improperly loaded for the correct tongue weight or the speed of the
vehicle and trailer is too high. Pull the vehicle-trailer over to a safe
location to check the trailer weight distribution and tongue load and
reduce speed to a safe level while towing. If trailer sway is
experienced, SLOW DOWN.
During trailer sway control events, the stability control light in the
instrument cluster will flash momentarily. The cluster message center
will also display TRAILER SWAY REDUCE SPEED. In some cases when
trailer sway is detected, the vehicle speed is too high and may be above
a speed at which trailer sway will not grow continuously. This may cause
the system to activate multiple times, causing a gradual reduction in
speed.
Note: The trailer sway control will only activate at speeds greater than
40 mph (64 km/h).
