Hill Start Assist (Hsa) - Dodge Durango 2015 Operating Information Manual

WARNING!
If TSC activates while driving, slow the ve-
hicle 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 direction
(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 with a
loaded vehicle, or while pulling a trailer,
when the system will not activate and slight
rolling may occur. This could cause a colli-
sion with another vehicle or object. Always
remember the driver is responsible for brak-
ing the vehicle.
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.
