•
Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in R (Reverse) gear).
HSA will work in R (Reverse) and all forward gears when
the activation criteria have been met. The system will not
activate if the vehicle is placed in N (Neutral) or P (Park).
WARNING!
There may be situations on minor hills (i.e., less than
8%), with a loaded vehicle, or while pulling a trailer,
when the system will not activate and slight rolling
may occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
Towing with HSA
HSA will provide assistance when starting on a grade
when pulling a trailer.
WARNING!
•
If you use a trailer brake controller with your
trailer, your trailer brakes may be activated and
deactivated with the brake switch. If so, when the
brake pedal is released there may not be enough
brake pressure to hold the vehicle and trailer on a
hill and this could cause a collision with another
vehicle or object behind you. In order to avoid
rolling down the hill while resuming accelera-
tion, manually activate the trailer brake prior to
releasing the brake pedal. Always remember the
driver is responsible for braking the vehicle.
•
HSA is not a parking brake. If you stop the
vehicle on a hill without putting the transmission
in P (Park) and using the parking brake, it will
roll down the hill and could cause a collision with
another vehicle or object. Always remember to
use the parking brake while parking on a hill,
and that the driver is responsible for braking the
vehicle.
