  • Prevent Pedal Bobble

    Grand Cherokee's Electronic Throttle Control (ETC) system help prevent the "pedal bobble" that often occurs when in 4LO. ETC's special off-road calibrations help the driver to "feather in" the throttle over uneven terrain, logs and rocks. The difference is night and day.
