WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver
when starting a vehicle from a stop on a hill.
HSA will maintain the level of brake pressure
the driver applied for a short period of time after
the driver takes their foot off of the brake pedal.
If the driver does not apply the throttle during
this short period of time, the system will release
brake pressure and the vehicle will roll down the
hill. The system will release brake pressure in
proportion to the amount of throttle applied as
the vehicle starts to move in the intended direc-
tion of travel.
HSA Activation Criteria
The following criteria must be met in order for
HSA to activate:
•
Vehicle must be stopped.
•
Vehicle must be on a 6% (approximate)
grade or greater hill.
•
Gear selection matches vehicle uphill direc-
tion (i.e., vehicle facing uphill is in forward
gear; vehicle backing uphill is in REVERSE
gear).
HSA will work in REVERSE and all forward
gears when the activation criteria have been
met. The system will not activate if the vehicle is
placed in NEUTRAL or 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 acceleration, 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 transmis-
sion in PARK and using the parking brake, it
will roll down the hill and could cause a
collision with another vehicle or object. Al-
ways remember to use the parking brake
while parking on a hill, and that the driver is
responsible for braking the vehicle.
