Driver Side - Jeep wrangler unlimited 2009 Owner's Manual

2009 WRANGLER/WRANGLER UNLIMITED
WRANGLER FEATURES/FUNCTIONS
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
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
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
* See the "Disclaimers" list.
