OFF-ROAD CAPABILITIES • Shifting into or out of Rear E-Locker is possible with the vehicle completely stopped; however, difficulty may occur due to the mating clutch teeth not being properly aligned. Several attempts may be required for clutch teeth alignment and shift completion to occur. The preferred method is for the vehicle to be rolling, below 15 MPH (24 km/h), while including right and left steering maneuvers to allow for the clutch teeth to align. • The Rear E-Locker System must be disengaged prior to taking the vehicle out of 4X4 LOW range. If 4X4 LOW shift conditions/interlocks are not met, a message will flash from the Electronic Vehicle Information Center (EVIC)/Driver Information Display with instructions on how to complete the requested shift. SELEC-TERRAIN™ • Selec-Terrain™ combines the capabilities of the vehicle control systems, along with driver input, to provide the best performance for all terrains. Rotate the mode control knob to select the following Selec-Terrain™ positions: • Auto - Fully automatic full time fourwheel drive operation can be used on and off road. Balances traction with seamless steering feel to provide improved handling and acceleration over two-wheel drive vehicles. • Snow - Tuning set for additional stability in inclement weather. Use on and Selec-Terrain™ Switch off road on loose traction surfaces such as snow. When in SNOW mode (depending on certain operating conditions), the transmission may use second gear (rather than first gear) during launches, to minimize wheel slippage. • Sport - This mode alters the transmission's automatic shift schedule for sportier driving. Upshift speeds are increased to make full use of available engine power. • Sand/Mud - Off road calibration for use on low traction surfaces such as mud, sand, or wet grass. Driveline is maximized for traction. Some binding may be felt on less forgiving surfaces. The electronic brake controls are set to limit traction control management of throttle and wheel spin. • Rock - Off-road calibration only available in 4WD LOW range. Traction based tuning with improved steer-ability for use on high traction off-road surfaces. Activate the Hill Descent Control for steep downhill control. Use for low speed obstacles such as large rocks, deep ruts, etc. NOTE: SPORT mode is not available when 4X4 LOW is selected. 165
