You may experience a brief vehicle vibration upon acceleration when driving in slippery conditions. This is normal and is an indication that the all-wheel drive system is functioning properly. Windows Manual Windows To open your manual windows, turn the hand crank on each door to raise or lower your side door windows. If you have the optional power windows, the controls are on each of the front side doors. The driver's door has a switch for the front passenger window as well. Your power windows will not move unless the ignition has been turned to RUN or ACCESSORY, or retained accessory power is present. See "Retained Accessory Power" in the Index.
