Four Wheel Drive (4WD) Systems: Overview

Four Wheel Drive (4WD) Systems

Overview

The AWD (All-Wheel Drive) system is always active and only requires the operator to select terrain. Torque from the engine is transferred through the transaxle to the PTU (Power Transfer Unit). The PTU (Power Transfer Unit) is a mechanical device attached to the transaxle. This torque is transferred through the driveshaft to the rear axle, which drives the rear halfshafts. The driver can optimize the AWD (All-Wheel Drive) system by setting the ATCM (All Terrain Control Module) switch for the correct terrain.
