502 STARTING AND OPERATING
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 acceleration,
manually activate the trailer brake prior to releas-
ing 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 PARK
and using the parking brake, it will roll down the
hill and could cause a collision with another ve-
hicle or object. Always remember to use the park-
ing brake while parking on a hill, and that the
driver is responsible for braking the vehicle.
HSA Off
If you wish to turn off the HSA system, it can be done
using the Customer Programmable Features in the Elec-
tronic Vehicle Information Center (EVIC). Refer to "Elec-
tronic Vehicle Information Center (EVIC)" in "Under-
standing Your Instrument Panel" for further information.
