USING FOUR-WHEEL DRIVE
WARNING
For important information regardingsafe operation of this type of vehicle,see General Information in theWheels and Tires chapter.
Note:Do not use 4H or 4L mode on dry,hard surfaced roads. Doing so will produceexcessive noise, increase tire wear and maydamage drive components. 4H and 4L modeis only intended for consistently slippery orloose surfaces.
Note:If 4L mode is selected while yourvehicle 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 forproper operation.
4WD Indicator Lights
The indicator lights illuminate in theinformation display in the reconfigurabletelltale (RTT) location under the followingconditions. See Warning Lamps andIndicators (page 87).
Note:When a 4X4 system fault is present,the system will typically remain in whichever4WD mode was selected prior to the faultcondition occurring. It will not default to 4X2in all circumstances. When this warning isdisplayed, have your vehicle serviced by anauthorized dealer.
4X2
Momentarily illuminates when2H is selected.
4X4 AUTO
Continuously illuminates when4A is selected.
4X4 HIGH
Continuously illuminates when4H is selected.
4X4 LOW
Continuously illuminates when4L is selected.
4WD Switch Positions
WARNING
Utility and four-wheel drive vehiclesare not designed for cornering atspeeds as high as passenger cars anymore than low-slung sports cars aredesigned to perform satisfactorily underoff-road conditions. Avoid sharp turns orabrupt maneuvers in these vehicles.
Note:If your vehicle is equipped withAdvanceTrac® with RSC®, the system willautomatically turn off the stabilityenhancement feature when you shift the4WD system into 4L (4X4 LOW). You canmanually turn the system off by pressingthe AdvanceTrac button. See UsingTraction Control (page 176). This willdisable the engine management feature,allowing the vehicle to maintain full powerand enhanced momentum through theobstacle. The brake traction enhancementfeature will still be enabled.
Note:The Control Trac® selector switchshould not be changed while the rear wheelsare slipping.

The Control Trac® system functions in fourmodes:
•2H delivers power to the rear wheelsonly. The information display willmomentarily display 2H when thismode is selected. This mode isappropriate for normal on-road drivingon dry pavement and provides the bestfuel economy.
•4A provides electronic controlfour-wheel drive with power deliveredto all four wheels, as required, forincreased traction. The informationdisplay will display 4A when this modeis selected. This mode is appropriatefor all on-road driving conditions, suchas dry road surfaces, wet pavement,snow, or gravel.
•4H provides electronically lockedfour-wheel drive power to front andrear wheels. The information displaywill display 4H when this mode isselected. This mode is notrecommended for use on drypavement. This mode is only intendedfor severe winter or off-road conditions,such as deep snow, ice or shallow sand.
•4L provides electronically lockedfour-wheel drive when extra power atreduced speeds is required. Theinformation display will display 4Lwhen this mode is selected. This modeis not recommended for use on drypavement. Use this mode for off-roadlow-speed operation or when extrapower is required, such as climbingsteep grades, going through deep sandor pulling a boat out of the water.
Shifting between system modes
Note:Momentarily releasing the acceleratorpedal while a shift in progress messagedisplays will improveengagement/disengagement performance.
Note:Do not perform this operation if therear wheels are slipping.
Note:Some noise may be heard as thesystem shifts or engages; this is normal.
You can move the control from 2H, 4A or4H at a stop or while driving. Theinformation display may display a messageindicating a 4X4 shift is in progress. Oncethe shift is complete the informationdisplay will then display the system modeselected.
Shifting to or from 4L
Note:4L mode is not intended for use ondry pavement.
1. Bring the vehicle to a rolling speed of3 mph (5 km/h) or less.
2. Place the gearshift in neutral (N).

The transfer case supples power to all fourwheels. On four-wheel drive vehicles, thetransfer case allows you to select different4WD modes when necessary. You can findinformation on transfer case operation andshifting procedures in this chapter. You canfind information on transfer casemaintenance in the Maintenance chapter.You should become thoroughly familiarwith this information before you operateyour vehicle.
Four-wheel drive (when you select a 4WDmode) uses all four wheels to power yourvehicle. This increases traction, enablingyou to drive over terrain and roadconditions that a conventional two-wheeldrive vehicle cannot.
Basic Operating Principles
•Do not use 4H or 4L on dry, hardsurfaced roads. Doing so will produceexcessive noise, increase tire wear andmay damage drive components. 4H or4L modes are only intended forconsistently slippery or loose surfaces.
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•When driving your vehicle on surfacesmade slippery by loose sand, water,gravel, snow or ice proceed with care.
If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce yourvehicle speed and avoid severe braking.When your vehicle speed decreases, easeyour vehicle back onto the road. Do notturn the steering wheel sharply whilereturning your vehicle to the road.
It may be safer to stay on the shoulder ofthe road and slow down gradually beforereturning to the road. You may lose controlif you do not slow down or if you turn thesteering wheel too sharply or abruptly.
It may be less risky to strike small objects,such as freeway reflectors, with minordamage to your vehicle rather thanattempt a sudden return to the road whichcould cause your vehicle to slide sidewaysout of control or roll over. Remember, yoursafety and the safety of others should beyour primary concern.
If your vehicle gets stuck
WARNING
Do not spin the wheels at over 35mph (56 km/h). The tires may failand injure a passenger or bystander.
Note:Do not rock your vehicle if the engineis not at normal operating temperature,damage to the transmission may occur.
Note:Do not rock your vehicle for morethan a minute, damage to the transmissionand tires may occur or the engine mayoverheat.
If your vehicle gets stuck in mud or snow itmay be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts, in a steady pattern. Presslightly on the accelerator in each gear.
Emergency Maneuvers
In an unavoidable emergency situationwhere a sudden sharp turn must be made,remember to avoid over-driving yourvehicle (i.e. turn the steering wheel only asrapidly and as far as required to avoid theemergency). Excessive steering can resultin loss of vehicle control. Apply smoothpressure to the accelerator pedal or brakepedal when changes in vehicle speed arerequired. Avoid abrupt steering,acceleration and braking. This could resultin an increased risk of vehicle roll over, lossof vehicle control and personal injury. Useall available road surface to bring yourvehicle to a safe direction of travel.

Four-Wheel Drive (If Equipped)

In the event of an emergency stop, avoidskidding the tires and do not attempt anysharp steering wheel movements.
If your vehicle goes from one type ofsurface to another (i.e. from concrete togravel) there will be a change in the wayyour vehicle responds to a maneuver (i.e.steering, acceleration or braking).
Sand
When driving over sand, try to keep all fourwheels on the most solid area of the trail.Avoid reducing the tire pressures but shiftto a lower gear and drive steadily throughthe terrain. Apply the accelerator slowlyand avoid excessive wheel slip.
Avoid driving at excessive speeds, thiscauses vehicle momentum to work againstyou and your vehicle could become stuckto the point that assistance may berequired from another vehicle. Remember,you may be able to back out the way youcame if you proceed with caution.
Mud and Water
Note:Driving through deep water maydamage the vehicle.
If you must drive through high water, driveslowly. Traction or brake capability maybe limited.
When driving through water, determine thedepth and avoid water higher than thebottom of the hubs. If the ignition systemgets wet, your vehicle may stall.
Once through water, always try the brakes.Wet brakes do not stop your vehicle aseffectively as dry brakes. Drying can beimproved by applying light pressure to thebrake pedal while moving slowly.
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even 4WD vehicles can lose tractionin slick mud. As when you are driving oversand, apply the accelerator slowly andavoid spinning your wheels. If the vehicledoes slide, steer in the direction of the slideuntil you regain control of the vehicle.
If the transmission, transfer case or frontaxle are submerged in water, their fluidsshould be checked and changed, ifnecessary.
If the front or rear axle is submerged inwater, the axle lubricant should bereplaced.
After driving through mud, clean off residuestuck to rotating driveshafts and tires.Excess mud stuck on tires and rotatingdriveshafts causes an imbalance thatcould damage drive components.

Driving on Hilly or Sloping Terrain
Note:Avoid driving crosswise or turning onsteep slopes or hills.
169
Expedition (TB7) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing
Four-Wheel Drive (If Equipped)E143950

Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.Whenever driving on a hill, determinebeforehand the route you will use. Do notdrive over the crest of a hill without seeingwhat conditions are on the other side. Donot drive in reverse over a hill without theaid of an observer.
Although natural obstacles may make itnecessary to travel diagonally up or downa hill or steep incline, you should alwaystry to drive straight up or straight down.
When climbing a steep slope or hill, startin a lower gear rather than downshifting toa lower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If your vehicle stalls, do not try to turnaround because this could cause vehicleroll over. It is better to reverse back to asafe location.
Apply just enough power to the wheels toclimb the hill. Too much power will causethe tires to slip, spin or lose traction,resulting in loss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating.Do not descend in neutral. Disengageoverdrive or move the transmissionselector lever to a lower gear. Whendescending a steep hill, avoid sudden hardbraking as you could lose control. The frontwheels have to be turning in order to steeryour vehicle.
If your vehicle has anti-lock brakes, applythe brakes steadily. Do not pump thebrakes.
Driving on Snow and Ice
WARNING
If you are driving in slipperyconditions that require tire chains orcables, then it is critical that you drivecautiously. Keep speeds down, allow forlonger stopping distances and avoidaggressive steering to reduce the chancesof a loss of vehicle control which can leadto serious injury or death. If the rear end ofyour vehicle slides while cornering, steer inthe direction of the slide until you regaincontrol of your vehicle.
Four-wheel drive vehicles have advantagesover two-wheel drive vehicles in snow andice but can skid like any other vehicle.Should you start to slide while driving onsnowy or icy roads, turn the steering wheelin the direction of the slide until you regaincontrol.
Avoid sudden applications of power andquick changes of direction on snow andice. Apply the accelerator slowly andsteadily when starting from a full stop.

PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL
WARNING
The stability and traction controllight illuminates steadily if thesystem detects a failure. Make sureyou did not manually disable the tractioncontrol system using the switch. If thestability control and traction control lightis still illuminating steadily, have thesystem serviced by an authorized dealerimmediately. Operating your vehicle withtraction control disabled could lead to anincreased risk of loss of vehicle control,vehicle rollover, personal injury and death.
The system automatically turns on eachtime you switch the ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Note:When you switch traction control off,stability control remains fully active.
Switching the System Off
The switch for the stability and tractioncontrol system is on the instrument panel.
When you switch the system off, amessage and an illuminated icon appearon the instrument cluster.
Use the switch again to return the tractioncontrol system to normal operation.
Your vehicle may have MyKey restrictionsregarding this feature. See Principle ofOperation (page 47).
System Indicator Lights andMessages
The stability and traction controllight temporarily illuminates onengine start-up and flashes:
•When a driving condition activateseither of the systems.
•If a problem occurs in either of thesystems.
The stability and traction controloff light temporarily illuminateson engine start-up and stays on:
•When you switch the traction controlsystem off.
•When you select an alternative stabilitycontrol mode.

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involvingbraking system, aftermarket roofracks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronic stabilitycontrol system. In addition, installing anystereo loudspeakers may interfere withand adversely affect the electronic stabilitycontrol system. Install any aftermarketstereo loudspeaker as far as possible fromthe front center console, the tunnel, andthe front seats in order to minimize the riskof interfering with the electronic stabilitycontrol sensors. Reducing theeffectiveness of the electronic stabilitycontrol system could lead to an increasedrisk of loss of vehicle control, vehiclerollover, personal injury and death.
Remember that even advancedtechnology cannot defy the laws ofphysics. It’s always possible to losecontrol of a vehicle due to inappropriatedriver input for the conditions. Aggressivedriving on any road condition can causeyou to lose control of your vehicleincreasing the risk of personal injury orproperty damage. Activation of theelectronic stability control system is anindication that at least some of the tireshave exceeded their ability to grip the road;this could reduce the operator’s ability tocontrol the vehicle potentially resulting ina loss of vehicle control, vehicle rollover,personal injury and death. If your electronicstability control system activates, SLOWDOWN.
The system automatically turns on eachtime you switch the ignition on.
If a fault occurs in either the stabilitycontrol or the traction control system, youmay experience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and tractioncontrol systems do not enhance yourvehicle's ability to maintain traction ofthe wheels.
If a driving condition activates either thestability control or the traction controlsystem you may experience the followingconditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe andyour foot is not on the brake, the brakepedal may move as the system applieshigher brake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
The system enhances your vehicle’s abilityto prevent skids or lateral slides byapplying brakes to one or more of thewheels individually and, if necessary,reducing engine power.
Roll Stability Control
The system enhances your vehicle’s abilityto prevent rollovers by detecting yourvehicle’s roll motion and the rate at whichit changes by applying the brakes to oneor more wheels individually.
