Electronic Stability Control (Esc) - Dodge Challenger 2015 Operating Information Manual

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 amount of throttle applied as the
vehicle starts to move in the intended direction
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 3% (approximate) for
manual transmission and 6% (approximate)
for automatic transmissions.
• Gear selection matches vehicle uphill direc-
tion (i.e., vehicle facing uphill is in forward
gear; vehicle backing uphill is in REVERSE
gear).

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 Off
If you wish to turn off the HSA system, it can be
done in the Uconnect® settings. Refer to
"Uconnect® Settings" in "Understanding Your
Instrument Panel" for further information.

Electronic Stability Control (ESC)

This system enhances directional control and
stability of the vehicle under various driving
conditions. The ESC corrects for oversteering
and understeering the vehicle by applying the
brake of the appropriate wheel. Engine power
may also be reduced to assist in counteracting
the condition of oversteer or understeer and
help the vehicle maintain the desired path.
The ESC uses sensors in the vehicle to deter-
mine the path that the driver intends to steer the
vehicle and compares it to the actual path of the
vehicle. When the actual path does not match
the intended path, the ESC applies the brake of
the appropriate wheel to assist in counteracting
the condition of oversteer or understeer.
• Oversteer - when the vehicle is turning more
than appropriate for the steering wheel posi-
tion.
• Understeer - when the vehicle is turning less
than appropriate for the steering wheel posi-
tion.
WARNING!
The Electronic Stability Control System
(ESC) cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase the traction afforded by prevailing
road conditions. ESC cannot prevent all ac-
cidents, including those resulting from ex-
cessive speed in turns, driving on very slip-
