2009 Jeep Liberty Owner's Manual - Page 305

STARTING AND OPERATING 303 CAUTION! (Continued) • The 4WD LOCK position and 4WD LOW position are intended for loose or slippery road surfaces only. Driving in these positions on dry hardsurfaced roads may cause increased tire wear and damage to the driveline components. • When operating your vehicle in 4WD LOW, the engine speed is approximately three times that of the 2WD position or 4WD LOCK position at a given road speed. Take care not to over-speed the engine and do not exceed 25 mph (40 km/h). • Proper operation of four-wheel drive vehicles depends on tires of equal size, type, and circumference on each wheel. Any difference in tire size can cause damage to the transfer case. WARNING! • You or others could be injured if you leave the vehicle unattended with the transfer case in the NEUTRAL position without first fully engaging the parking brake. The transfer case NEUTRAL position disengages both the front driveshaft and rear driveshaft from the powertrain and it will allow the vehicle to move even if the transmission is in PARK. The parking brake should always be applied when the driver is not in the vehicle. • Always engage the parking brake when powering down the vehicle if the "SERV 4WD Warning Light" is illuminated. Not engaging the parking brake may allow the vehicle to roll, which may cause personal injury. (Continued) 5
