Information Displays

USING FOUR-WHEEL DRIVE
Note:For important information regardingthe safe operation of this type of vehicle,see General Information in the Wheels andTires chapter.
Note:Do not use 4H or 4L mode on dry,hard surfaced roads. Doing so can produceexcessive noise, increase tire wear and maydamage drive components. 4X4 mode isonly intended for consistently slippery orloose surfaces. Use of 4L mode on thesesurfaces may produce some noise (such asoccasional clunks), but will not damagedrive components.
Note:If 4X4 low is selected while thevehicle is moving above 3 mph (5 km/h),the 4WD system will not perform a shift.This is normal and should be no reason forconcern. Refer to Shifting to or from 4L (4X4Low) for proper operation.
Note:You can switch on and switch off theelectronic locking differential by pulling the4WD control (4WD vehicles) or turning theelectronic locking differential control (2WDvehicles). See Electronic LockingDifferential (page 219).
Manual Shift On Stop (MSOS)4WD system (If Equipped)
Note:The vehicle should not be driven in4X4 High or 4X4 Low modes with the hublocks set to FREE as this condition maydamage driveline system components.
The 4WD system is engaged or disengagedby rotating the control for both front wheelhub locks from the FREE or LOCK position,then manually engaging or disengaging thetransfer case with the floor-mountedshifter. For increased fuel economy in 2WD,rotate both hub locks to the FREE position.
Electronic Shift-On-the-Fly(ESOF) 4WD system (If Equipped)
Note:If 4X4 Low is selected while thevehicle is moving above 3 mph (5 km/h),the 4WD system will not perform a shift.This is normal and should be no reason forconcern. Refer to Shifting to or from 4L (4X4Low) for proper system operation.
Note:Auto-manual hub locks can bemanually overridden by rotating the hub lockcontrol from AUTO to LOCK.

LIMITED SLIP DIFFERENTIAL
This axle provides added traction onslippery surfaces, particularly when onewheel is on a poor traction surface. Undernormal conditions, the limited-slip axlefunctions like a standard rear axle. The axlemay exhibit a slight noise or vibrationduring tight turns with low vehicle speed.This is normal behavior and indicates theaxle is working.
ELECTRONIC LOCKING
DIFFERENTIAL (If Equipped)
Note:The electronic locking differential isfor off-road use only and is not for use ondry pavement. Using the electronic lockingdifferential on dry pavement will result inincreased tire wear, noise and vibration.
The electronic locking differential is adevice housed in the rear axle that allowsboth rear wheels to turn at the samespeed. The electronic locking differentialcan provide additional traction should yourvehicle become stuck. You can activatethe differential electronically and shift iton the fly within the differential operatingspeed range. The differential is for use inmud, rocks, sand, or any off-road conditionwhere you need maximum traction. It isnot for use on dry pavement.
The following conditions will affect theelectronic locking differential:
•The electronic locking differential willnot engage if your vehicle speed isabove 20 mph (32 km/h) in 4x2, 4x4Auto, or 4x4 High modes.
•The electronic locking differential willnot engage if your vehicle speed isabove or 56 mph (90 km/h) in 4X4Low.
•The electronic locking differential maynot engage if you press youraccelerator pedal during anengagement attempt. A message maydisplay in the instrument displayguiding you to release the acceleratorpedal.
•In 4x2, 4x4 Auto, and 4x4 High modes,the electronic locking differential willautomatically disengage at speedsabove 25 mph (41 km/h) and willautomatically reengage at speedsbelow 20 mph (32 km/h).
•In 4L (4X4 low), the electronic lockingdifferential will automaticallydisengage at speeds above 62 mph(100 km/h) and will automaticallyreengage at speeds below 56 mph(90 km/h).
•The AdvanceTrac system has theability to take over control of theelectronic locking differential anddisable it during driving maneuverswhen necessary.
When you switch the system on, if you donot meet the required conditions forelectronic locking differential activation,the instrument cluster will display theappropriate information guiding youthrough the proper activation process.
Activating the Electronic LockingDifferential
Note:Do not use electronic lockingdifferential on dry, hard surfaced roads.Doing so will produce excessive noise,vibration and increase tire wear.
Note:If the electronic locking differentialhas difficulty disengaging, release theaccelerator pedal and turn the steeringwheel in the opposite direction while rolling.

For 4WD vehicles
Pull the 4WD control knob toward you.
For 2WD vehicles
Turn the control to ON.
Once the indicator lightilluminates in the informationdisplay, both rear wheel axleshafts will be locked together providingadded traction.
If the indicator does not come on, or theindicator turns off while driving, one of thefollowing has occurred:
•The vehicle speed is too high.
•The left and right rear wheel speeddifference is too high during anengagement attempt.
•The system has malfunctioned and isaccompanied by CHECK LOCKINGDIFFERENTIAL in the informationdisplay. See your authorized Forddealer for assistance.
