Four-Wheel Drive (If Equipped) 4WD switch positions 191 WARNING: Utility and four-wheel drive vehicles are not designed for cornering at speeds as high as passenger cars any more than low-slung sports cars are designed to perform satisfactorily under off-road conditions. Avoid sharp turns or abrupt maneuvers in these vehicles. Note: If your vehicle is equipped with AdvanceTrac® with RSC®, the system will automatically turn off the stability enhancement feature when you shift the 4WD system into 4L (4X4 LOW). You can manually turn the system off by pressing the AdvanceTrac button, see the Traction Control chapter for more information. This will disable the engine management feature, allowing the vehicle to maintain full power and enhanced momentum through the obstacle. The brake traction enhancement feature will still be enabled. Note: The Control Trac® selector knob should not be changed while the rear wheels are slipping. The Control Trac® 4WD system 2H functions in four modes: 4A • 2H (4X2) delivers power to the 4H rear wheels only. The message center will momentarily display 4L 4x2 when this mode is selected. This mode is appropriate for normal on-road driving on dry pavement and provides best fuel economy. • 4A (4X4 AUTO) provides electronic control four-wheel drive with power delivered to all four wheels, as required, for increased traction. The message center will display "4X4 AUTO" when this mode is selected. This mode is appropriate for all on-road driving conditions, such as dry road surfaces, wet pavement, snow or gravel. • 4H (4X4) provides electronically locked four-wheel drive power to front and rear wheels. The message center will display 4X4 when this mode is selected. This mode is not recommended for use on dry pavement. This mode is only intended for severe winter or off-road conditions, such as deep snow, ice or shallow sand. 2014 Expedition (exd) Owners Guide gf, 1st Printing, June 2013 USA (fus)
