Towing And Hauling With HSA
The HSA system does not know if your vehicle
is loaded or towing a trailer unless the TOW/
HAUL switch, located on the center stack, is
selected. When activated, the “TOW/HAUL In-
dicator Light” will illuminate in the instrument
cluster. Refer to “Automatic Transmission” in
“Starting and Operating” for further information.
In order to accommodate the extra weight en-
tailed under towing and hauling conditions and
to increase driver comfort while launching on a
hill, the system recognizes when the TOW/
HAUL switch is activated 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 behind 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 re-
sponsible for braking the vehicle.
•
HSA is not a parking brake. If you stop the
vehicle on a hill without putting the trans-
mission in PARK or using the parking
brake, it will roll down the incline and could
collide with another vehicle, object or per-
son, and cause serious or fatal injury.
Always remember to use the parking brake
while parking on a hill and that the driver is
responsible for braking the vehicle.
HSA Off
HSA is a Customer Programmable Feature in
the EVIC/DID. If you wish to turn off the HSA
feature, refer to “Electronic Vehicle Information
Center (EVIC)/Driver Information Display (DID)”
in “Understanding Your Instrument Panel” for
further information.
Electronic Stability Control (ESC)
The ESC system enhances directional control
and stability of the vehicle under various driving
conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the
brake of the appropriate wheel to assist in
counteracting the oversteer or understeer con-
dition. Engine power may also be reduced to
help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
