Dodge 2009 Ram 3500 Automobile User Manual


 
The system will only work if the intended direction of the
vehicle and vehicle gear match. For example, if the
intended direction is forward up a hill and the vehicle is
in DRIVE, and the activation criteria are met, HSA will
activate.
HSA on Automatic Transmission Vehicles
The system will work in REVERSE and all forward gears
on vehicles equipped with an automatic transmission.
The system will not activate if the vehicle is placed in
NEUTRAL.
Towing and Hauling with HSA (Vehicles Equipped
with Automatic Transmissions Only)
The HSA system does not know if your vehicle is loaded
or towing a trailer, unless the TOW/HAUL button,
located on the shift lever, is selected. When activated, the
TOW/HAUL light will illuminate in the instrument
cluster. For more information on the TOW/HAUL mode,
refer to “When To Use TOW/HAUL and O/D OFF
Modes” under ЉAutomatic Transmission” in Section 5. In
order to accommodate the extra weight entailed under
towing and hauling conditions and to increase driver
comfort while launching on a hill, the system recognizes
when the TOW/HAUL button is activated and compen-
sates by releasing brake pressure at a slower rate while
throttle is applied in order to prevent the vehicle from
rolling down the hill.
