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).
• 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
distance to other vehicles, people, and objects, and
most importantly brake operation to ensure 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 acceleration on an
incline while towing a trailer.
