DRIVER SIDE
WRANGLER FEATURES/FUNCTIONS
CUSTOMER BENEFITS
ELECTRONIC STABILITY PROGRAM (ESP)*
Compares the driver’s intended course with the
•
vehicle’s actual course and then compensates
for differences
Senses when a vehicle is starting to spin (oversteer)
•
or plow (understeer)
Helps to correct the vehicle’s course by
•
automatically adjusting the throttle and applying the
brakes at individual wheel
Automatically helps/assists driver in maintaining
•
control of vehicles during extreme steering
maneuvers
Provides added driving confi dence, particularly
•
in rain and snow
ELECTRONIC ROLL MITIGATION (ERM)
Monitors the driver’s steering wheel input and the
•
speed of the vehicle to sense the potential for
wheel lift
Detects when the sudden buildup of lateral force
•
during a severe turn or evasive maneuver can
cause the vehicle to start to tip
Applies the brakes with a high burst of pressure
•
to cause the outside tire to slip and the vehicle’s
weight to transfer back over the inside tires and
helps keep all four tires solidly on the ground
A component of the ABS/ESP* system
•
Provides an enhancement to the Electronic Stability
•
Program* to help reduce the likelihood of a vehicle
side rollover
Reduces the chance of a rollover in sudden
•
maneuvers and evasive events
Provides additional security and confi dence by
•
keeping all four wheels solidly on the ground
Especially useful in vehicles with a higher center
•
of mass
ALL SPEED TRACTION CONTROL
Monitors the amount of wheel spin of each of the
•
driven wheels
Applies brake pressure to the slipping wheel(s)
•
and reduces engine power to provide enhanced
acceleration and stability
Controls the wheel spin across a driven axle (similar
•
to limited-slip differential)
If one wheel on a driven axle is spinning faster
–
than the other, the system will apply the brake
and slow down that wheel
Allows more engine torque to be successfully
–
applied to the wheel if it is not spinning
Helps reduce wheel slip as the vehicle
•
is accelerating
Provides increased driving confi dence on all road
•
surfaces, but especially on sand and gravel, as well
as wet and snowy roads
