Jeep Liberty: Electronic Stability Control (ESC)
This 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 condition. 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. When the actual path does not match the intended path, ESC applies the brake of the appropriate wheel to assist in counteracting the oversteer or understeer condition.
вЂў Oversteer - when the vehicle is turning more than appropriate for the steering wheel position.
вЂў Understeer - when the vehicle is turning less than appropriate for the steering wheel position.
The вЂњESC Activation/Malfunction Indicator LightвЂќ located in the instrument cluster will start to flash as soon as the tires lose traction and the ESC system becomes active. The вЂњESC Activation/Malfunction Indicator LightвЂќ also flashes when the TCS is active. If the вЂњESC Activation/Malfunction Indicator LightвЂќ begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions.
The Electronic Stability Control (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 collisions, including those resulting from excessive speed in turns, driving on very slippery surfaces, or hydroplaning. The capabilities of an ESC equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the userвЂ™s safety or the safety of others.
ESC Operating Modes
Depending upon model and mode of operation, the ESC system has up to three operating modes: вЂњESC OnвЂќ вЂњPartial Off,вЂќ and вЂњFull Off.вЂќ
ESC On вЂ“ Two-Wheel Drive Vehicles And Four-Wheel Drive Vehicles In 2WD And 4WD High Range
This is the normal operating mode for ESC when operating a two-wheel drive vehicle. It is also the normal mode for operating a four-wheel drive vehicle in 2WD or 4WD HIGH range. The ESC system will be in вЂњESC OnвЂќ mode whenever the vehicle is started or the transfer case (if equipped) is shifted out of 4WD LOW range. This mode should be used for most driving situations. ESC should only be turned to вЂњPartial OffвЂќ or вЂњFull OffвЂќ for specific reasons as noted. Refer to вЂњPartial OffвЂќ and to вЂњFull OffвЂќ for additional information.
Partial Off вЂ“ Two-Wheel Drive Vehicles And Four-Wheel Drive Vehicles In 2WD And 4WD High Range
The вЂњPartial OffвЂќ mode is intended for driving in deep snow, sand, or gravel. This mode raises the threshold for TCS and ESC activation, which allows for more wheel spin than what ESC normally allows.
The вЂњESC OffвЂќ button is located in the lower switch bank below the climate control. To enter the вЂњPartial OffвЂќ mode, momentarily press the вЂњESC OffвЂќ button and the ESC Activation/Malfunction Indicator LightвЂќ will illuminate.
To turn the ESC on again, momentarily press the ESC Off button and the ESC Activation/Malfunction Indicator LightвЂќ will turn off. This will restore the normal вЂњESC OnвЂќ mode of operation.
NOTE: To improve the vehicleвЂ™s traction when driving with snow chains, or when starting off in deep snow, sand, or gravel, it may be desirable to switch to the вЂњPartial OffвЂќ mode by momentarily pressing the вЂњESC OffвЂќ button. Once the situation requiring вЂњPartial OffвЂќ mode is overcome, turn ESC back on by momentarily pressing the вЂњESC OffвЂќ button. This may be done while the vehicle is in motion.
Full Off вЂ“ Four-Wheel Drive Vehicles In 4WD High And 4WD Low Range
The вЂњFull OffвЂќ mode is intended for off-highway and off-road use when ESC stability features could inhibit vehicle maneuverability due to trail conditions.
The вЂњESC OffвЂќ button is located in the lower switch bank below the climate control panel. To enter вЂњFull OffвЂќ mode, press and hold the вЂњESC OffвЂќ button for five seconds while the vehicle is stopped with the engine running. After five seconds, the вЂњESC Activation/ Malfunction Indicator LightвЂќ will illuminate and an вЂњESC OFFвЂќ message will appear in the odometer. Press and release the trip odometer button located on the instrument cluster to turn off this message.
In this mode, ESC and TCS are turned off (except for the вЂњlimited slipвЂќ feature described in the TCS section) until the vehicle reaches a speed of 40 mph (64 km/k). At speeds over 40 mph (64 km/k), the system automatically switches to вЂњPartial OffвЂќ mode, described above. When the vehicle speed returns to less than 35 mph (56 km/h), the ESC system will return to вЂњFull OffвЂќ mode. The вЂњESC Activation/Malfunction Indicator LightвЂќ is always illuminated when ESC is off. To turn ESC on again, momentarily press the вЂњESC OffвЂќ button. This will restore the normal вЂњESC OnвЂќ mode of operation.
вЂў вЂњFull OffвЂќ is the only operating mode for ESC in 4WD LOW range. The ESC system will be in this mode whenever the vehicle is started in 4WD LOW range or the transfer case is shifted into 4WD LOW range.
вЂў The вЂњESC OFFвЂќ message will display and a chime will sound when the shift lever is moved from any position to the PARK position and then moved out of the PARK position. This will occur even if the message was cleared previously.
With the ESC switched off, the enhanced vehicle stability offered by ESC is unavailable. In an emergency evasive maneuver, the ESC system will not engage to assist in maintaining stability. вЂњFull OffвЂќ mode is only intended for off-highway or off-road use.
