• For vehicles equipped with an automatic
transmission, the HSA will work in REVERSE
gear and all forward gears. The system will
not activate if the transmission is in PARK.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills (i.e., less
than 7%), or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for
active driving involvement. It is always the
driver's responsibility to be attentive to dis-
tance to other vehicles, people, and objects,
and most importantly brake operation to en-
sure safe operation of the vehicle under all
road conditions. Your complete attention is
always required while driving to maintain safe
control of your vehicle. Failure to follow these
warnings can result in a collision or serious
personal injury.
Towing With HSA
HSA will provide assistance during accelera-
tion on an incline while towing a trailer.

WARNING!
• If you use a trailer brake controller with your
trailer, the trailer brakes may be activated
and deactivated with the brake switch. If so,
there may not be enough brake pressure to
hold both the vehicle and the trailer on a hill
when the brake pedal is released. In order
to avoid rolling down an incline while re-
suming acceleration, manually activate the
trailer brake or apply more vehicle brake
pressure prior to releasing the brake pedal.
• HSA is not a parking brake. Always apply
the parking brake fully when leaving your
vehicle. Also, be certain to leave the trans-
mission in PARK.
• Failure to follow these warnings may cause
the vehicle to roll down the incline and
could collide with another vehicle, object or
person, and cause serious or fatal injury.
Always remember to use the parking brake
while parking on a hill and that the driver is
responsible for braking the vehicle.
