Dodge 2008 Ram Pickup 1500 - Manual (Page 330)

HSA (Hill Start Assist)
The HSA system is designed to assist the driver in
launching a vehicle on an incline. HSA will maintain the
level of brake pressure the driver inputs for a short
duration once the driver takes his foot off of the brake
pedal. If the driver does not apply the throttle during this
short duration, the system will release brake pressure
and the vehicle will roll down the incline. The system will
release brake pressure in proportion to the amount of
throttle applied.
During operation, Hill Start Assist will activate the brake
control system and a clicking noise will occur. If your foot
is on the brake pedal during operation you may feel a
slight pedal movement. The clicking and pedal move-
ment is normal and both will stop when HSA becomes
inactive.
WARNING!
If the clutch pedal (manual vehicles only) remains
depressed during the application of the throttle, the
HSA will disengage allowing the vehicle to roll
down the incline. This could cause a collision with
another vehicle or object. To avoid this, do not apply
throttle while depressing the clutch pedal until you
are ready to release the clutch. Always remember the
driver is responsible for braking the vehicle.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
• Vehicle must be stopped
• Vehicle must be on a 7% or greater incline
