260 STARTING AND OPERATING Quadra-Drive II System - If Equipped The optional Quadra-Drive II System features three torque transfer couplings. The couplings include Electronic Limited-Slip Differential (ELSD) front and rear axles and Quadra-Trac II transfer case. The optional ELSD axles are fully automatic and require no driver input to operate. Under normal driving conditions, the units function as standard axles, balancing torque evenly between left and right wheels. With a traction difference between left and right wheels, the coupling will sense a speed difference. As one wheel begins to spin faster than the other, torque will automatically transfer from the Neutral Switch wheel that has less traction, to the wheel that has traction. 5. Repeat Steps 1 to 4 to shift out of NEUTRAL. While the transfer case and axle couplings differ in design, their operation is similar. Follow the Quadra-Trac NOTE: If shift conditions/interlocks are not met, a II transfer case shifting information, preceding this "CHECK SHIFT PROCEDURES" message will flash from section, for shifting this system. the Electronic Vehicle Information Center (EVIC). Refer to "Electronic Vehicle Information Center (EVIC)" in Section 4 of this manual.
