Jeep 2008 Liberty - Manual (Page 319)

WARNING!
• TSC (Trailer Sway Control) cannot stop all trailers
from swaying. Always use caution when towing a
trailer and follow the tongue weight recommenda-
tions. Refer to ”Vehicle Loading” and “Trailer
Towing” in this section for more information be-
fore towing a trailer with your vehicle.
• If TSC activates while towing a trailer, stop the
vehicle at the nearest safe location and adjust the
trailer load to eliminate the trailer sway.
• Failure to follow these warnings can result in an
accident or serious personal injury.
HSA (Hill Start Assist)
The HSA system is designed to help the driver accelerate
the vehicle from a complete stop while on an incline. If
the driver releases the brake while stopped on an incline,
HSA will continue to hold the brake pressure for a short
period. If the driver does not apply the throttle before this
time expires, the system will release brake pressure and
the vehicle will roll down the hill as normal. The system
will release brake pressure in proportion to amount of
throttle applied.
The following conditions must be met in order for HSA to
activate:
• The vehicle must be stopped.
• The vehicle must be on a 7% or greater incline.
• The Gear selection must match vehicle uphill direction
(i.e. vehicle facing uphill is in forward gear; vehicle
backing uphill is in reverse gear).
