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 transmission gear shift lever, is selected.
When activated, the TOW/HAUL light will illuminate in
the instrument cluster. For more information on TOW/
HAUL mode, refer to “When To USE TOW/HAUL and
O/D OFF Modes” under 9Automatic 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 acti-
vated and compensates by releasing brake pressure at a
slower rate while throttle is applied in order to prevent
the vehicle from rolling down the hill.
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 be-
hind you. In order to avoid rolling down the incline
while resuming acceleration, manually activate the
trailer brake or apply more vehicle brake pressure
prior to releasing the brake pedal. Always remember
the driver is responsible for braking the vehicle.
