acceleration or braking which could resultin an increased risk of loss of vehiclecontrol, vehicle rollover and/or personalinjury. Use all available road surface toreturn the vehicle to a safe direction oftravel.
•In the event of an emergency stop, avoidskidding the tires and do not attempt anysharp steering wheel movements.
•If the vehicle goes from one type ofsurface to another (that is, from concreteto gravel) there will be a change in theway the vehicle responds to a maneuver(steering, acceleration or braking). Again,avoid these abrupt inputs.
Sand
Most of the time traction control improvestire traction by managing wheel slip throughBrake, Engine, and AWD calibrations.However, during low speed driving, disablingtraction control in deep sand can help keepthe wheels moving to maintain vehiclemomentum.
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 slowly andavoid spinning the wheels.
Do not drive your vehicle in deep sand foran extended period of time. This could causethe AWD system to overheat and default tofront-wheel drive. If this occurs, an AWD OFFmessage displays in the information display.To resume normal AWD function as soon aspossible, stop the vehicle in a safe locationand stop the engine for at least 10 minutes.After the engine has been restarted and theAWD system has adequately cooled, theAWD OFF message turns off and normalAWD function returns. In the event theengine is not stopped, the AWD OFFmessage turns off when the system coolsand normal AWD function returns.
When driving at slow speeds in deep sandunder high outside temperatures, use L (Low)gear when possible. L (Low) gear operationwill maximize the engine and transmissioncooling capability.
Under severe operating conditions, the A/Cmay cycle on and off to protect overheatingof the engine.
Avoid excessive speed because vehiclemomentum can work against you and causethe vehicle to become stuck to the point thatassistance may be required from anothervehicle. Remember, you may be able to backout the way you came if you proceed withcaution.
Mud and Water
If you must drive through high water, driveslowly. Traction or brake capability may belimited.
When driving through water, determine thedepth; avoid water higher than the bottomof the wheel rims (for cars) or the bottom ofthe hubs (for trucks) (if possible) and proceedslowly. If the ignition system gets wet, thevehicle may stall.

Once through water, always try the brakes.Wet brakes do not stop the vehicle aseffectively as dry brakes. Drying can beimproved by moving your vehicle slowlywhile applying light pressure on the brakepedal.
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even AWD vehicles can lose tractionin slick mud. As when you are driving oversand, apply the accelerator slowly and avoidspinning your wheels. If the vehicle doesslide, steer in the direction of the slide untilyou regain control of the vehicle.
After driving through mud, clean off residuestuck to rotating driveshafts and tires. Excessmud stuck on tires and rotating driveshaftscauses an imbalance that could damagedrive components.
Note:Driving through deep water maydamage the transmission.
If the front or rear axle is submerged in water,have the power transfer unit (PTU) or rearaxle serviced by an authorized dealer.
Driving on Hilly or Sloping Terrain
Note:Avoid driving crosswise or turning onsteep slopes or hills. A danger lies in losingtraction, slipping sideways and possiblyrolling over. Whenever driving on a hill,determine beforehand the route you will use.Do not drive over the crest of a hill withoutseeing what conditions are on the other side.Do not drive in reverse over a hill withoutthe aid of an observer.
Although natural obstacles may make itnecessary to travel diagonally up or down ahill or steep incline, you should always try todrive straight up or straight down.
When climbing a steep slope or hill, start ina lower gear rather than downshifting to alower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If you do stall out, do not try to turnaroundbecause you might roll over. It is better toback down to a safe location.
Apply just enough power to the wheels toclimb the hill. Too much power will cause thetires to slip, spin or lose traction, resulting inloss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating. Donot descend in neutral; instead, disengageoverdrive or manually shift to a lower gear.When descending a steep hill, avoid suddenhard braking as you could lose control. Thefront wheels have to be turning in order tosteer the vehicle.

Hilly Condition Usage
You should select a lower gear when thesystem is active in situations such asprolonged downhill driving on steep grades,for example in mountainous areas. Thesystem needs additional engine braking inthese situations to reduce the load on thevehicle’s regular brake system to prevent itfrom overheating.
Note:An audible alarm sounds and thesystem shuts down if it applies brakes for anextended period of time. This allows thebrakes to cool. The system functionsnormally again after the brakes cool.

STEERING
Electric Power Steering
WARNING: The electric power steeringsystem has diagnostic checks thatcontinuously monitor the system. If a fault isdetected, a message displays in theinformation display. Stop your vehicle assoon as it is safe to do so. Switch the ignitionoff. After at least 10 seconds, switch theignition on and watch the information displayfor a steering system warning message. If asteering system warning message returns,have the system checked by an authorizeddealer.
WARNING: If the system detects anerror, you may not feel a difference in thesteering, however a serious condition mayexist. Obtain immediate service from anauthorized dealer, failure to do so may resultin loss of steering control.
Your vehicle has an electric power steeringsystem. There is no fluid reservoir. Nomaintenance is required.
If your vehicle loses electrical power whileyou are driving, electric power steeringassistance is lost. The steering system stilloperates and you can steer your vehiclemanually. Manually steering your vehiclerequires more effort.
Extreme continuous steering may increasethe effort required for you to steer yourvehicle. This increased effort preventsoverheating and permanent damage to thesteering system. You do not lose the abilityto steer your vehicle manually. Typicalsteering and driving maneuvers allow thesystem to cool and return to normaloperation.
Steering Tips
If the steering wanders or pulls, check for:
•Correct tire pressures.
•Uneven tire wear.
•Loose or worn suspension components.
•Loose or worn steering components.
•Improper vehicle alignment.

Driving Aids

Maintain coolant concentration within 48%to 50%, which equates to a freeze pointbetween -30°F (-34°C) and -34°F (-37°C).Coolant concentration should be checkedusing a refractometer. We recommend,Robinair® Coolant and Battery Refractometer75240 (Rotunda tool part number:ROB75240). We do not recommend the useof hydrometers or coolant test strips formeasuring coolant concentration.
Note: Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
Adding Coolant
WARNING: Do not add engine coolantwhen the engine is hot. Failure to follow thisinstruction could result in personal injury.
WARNING: Do not remove the coolantreservoir cap when the cooling system is hot.Wait 10 minutes for the cooling system tocool down. Cover the coolant reservoir capwith a thick cloth to prevent the possibilityof scalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
It is very important to use prediluted coolantmeeting the correct specification in order toavoid plugging the small passageways in theengine cooling system. See Capacities andSpecifications (page 373). Incorrectprediluted coolant use can cause damagenot covered by the vehicle Warranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant meeting thecorrect specification. See Capacities andSpecifications (page 366).
3.Add enough prediluted coolant to reachthe correct level.
4. Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.
5. Check the coolant level in the coolantreservoir the next few times you driveyour vehicle.
Note:During normal vehicle operation, thecoolant may change color from orange topink or light red. As long as the coolant isclear and uncontaminated, this color changedoes not indicate the coolant has degradednor does it require the coolant to be drained,the system to be flushed, or the coolant tobe replaced.
Do not mix different colors or types ofprediluted coolant in your vehicle. Mixing ofprediluted coolant or using an incorrectprediluted coolant may harm the engine orcooling system components and may not becovered by the vehicle Warranty.
In case of emergency, you can add a largeamount of water without engine coolant inorder to reach a vehicle service location. Inthis instance, qualified personnel:

Maintenance

1. Must drain the cooling system.
2. Chemically clean the cooling system.
3. Refill with prediluted coolant as soon aspossible.
Water alone, without prediluted coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection of thecoolant.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling process isnot yet available.
Dispose of used engine coolant in anappropriate manner. Follow yourcommunity's regulations and standards forrecycling and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60% providesimproved freeze point protection. Coolant concentrations above 60%decrease the overheat protectioncharacteristics of the coolant and maycause engine damage.
If you drive in extremely hot climates:
•It may be necessary to decrease thecoolant concentration to 40%.
•A coolant concentration of 40% providesimproved overheat protection. Coolantconcentrations below 40% decrease thefreeze and corrosion protectioncharacteristics of the coolant and maycause engine damage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambient temperature,vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the coolanttemperature gauge moves toward the redzone:

Maintenance

Engine Coolant TemperatureManagement (If Equipped)
WARNING: To reduce the risk of crashand injury, be prepared that the vehiclespeed may reduce and the vehicle may notbe able to accelerate with full power until thecoolant temperature reduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a long orsteep grade in high ambient temperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehicle speedcaused by reduced engine power in orderto manage the engine coolant temperature. Your vehicle may enter this mode if certainhigh-temperature and high-load conditionstake place. The amount of speed reductiondepends on vehicle loading, grade andambient temperature. If this occurs, there isno need to pull off the road. You cancontinue to drive your vehicle.
The air conditioning may automatically turnon and off during severe operatingconditions to protect the engine fromoverheating. When the coolant temperaturedecreases to the normal operatingtemperature, the air conditioning turns on.
If the coolant temperature gauge moves fullyinto the red zone, or if the coolanttemperature warning or service engine soonmessages appear in your information display,do the following:
1. Pull off the road as soon as safelypossible and shift the transmission intopark (P).
2. Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop after severalminutes, follow the remaining steps.
3. Switch the engine off and wait for it tocool. Check the coolant level.
4. If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5. If the coolant level is normal, restart theengine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK
6F35 Transmission (If Equipped)
Note:Transmission fluid should be checkedby an authorized dealer. If required, fluidshould be added by an authorized dealer.
The automatic transmission does not havea transmission fluid dipstick.

Maintenance

High fluid level
If the fluid level is above the MAX range ofthe dipstick, remove fluid to reach thehashmark level.
Note:Fluid level above the MAX level maycause shift or engagement concerns orpossible damage. High fluid levels can becaused by an overheating condition. If yourvehicle has been operated for an extendedperiod at high speeds, in city traffic duringhot weather or pulling a trailer, the vehicleshould be switched off until normal operatingtemperatures are reached. Depending onvehicle use, cooling times could take up to30 minutes or longer.
Adjusting Automatic Transmission FluidLevels
Before adding any fluid, make sure thecorrect type is used. The type of fluid usedis normally indicated on the dipstick and alsoin the Technical Specifications section in thischapter.
Note:An overfill condition of transmissionfluid may cause shift or engagementconcerns or possible damage.
Do not use supplemental transmission fluidadditives, treatments or cleaning agents. Theuse of these materials may affecttransmission operation and result in damageto internal transmission components.Reinstall the air filter assembly. After the fluidlevel has been checked and adjusted asnecessary, do the following:
1. Shut the engine off.
2. Loosen the clamp holding the air filterassembly to the rubber hose.
3.Rotate the air filter assembly 90 degreesclockwise without disconnecting thesensor.
4.Seat the air filter assembly back into thegrommets by pushing down on the airfilter assembly.
5. Tighten the clamp.
6. Install and tighten two bolts that attachair filter assembly to the front of thevehicle.
7. Install the bolt cover (if equipped).

Loss of air pressure may adversely affect tireperformance. For this reason:
Note:Do not drive the vehicle above 50 mph(80 km/h).
Note:Do not drive further than 120 mi(200 km). Drive only to the closest authorizedLincoln dealer or tire repair shop to haveyour tire inspected.
•Drive carefully and avoid abrupt steeringmaneuvers.
•Periodically monitor tire inflation pressurein the affected tire; if the tire is losingpressure, have the vehicle towed.
•Read the information in the Tips for Useof the Kit section to make sure safeoperation of the kit and your vehicle.
Tips for Use of your TMK
To ensure safe operation of the TMK:
•Read all instructions and cautions fully.
•Do not remove any foreign objects, suchas nails or screws, from the tire.
•Before operating the kit, make sure yourvehicle is safely off the road and awayfrom moving traffic. Turn on the hazardlights.
•Always set the parking brake to ensurethe vehicle doesn't move unexpectedly.
•When using the kit, leave the enginerunning (only if the vehicle is outdoors orin a well-ventilated area) so thecompressor does not drain the vehicle'sbattery.
•Do not allow the compressor to operatecontinuously for more than 15 minutes.This helps prevent the compressor fromoverheating.
•Never leave the kit unattended duringoperation.
•Sealant compound contains latex. Thosewith latex sensitivities should useappropriate precautions to avoid anallergic reaction.
•Keep the kit away from children.
•Only use the kit when the ambienttemperature is between -22°F (-30°C) and158°F (70°C).
•Only use the sealing compound beforethe use-by date. The use-by date is on alabel on the sealant bottle and can beseen through the rectangular viewingwindow on the bottom of the compressorhousing. Check the use-by date regularlyand replace the bottle when the fluid hasexpired.
•Do not store the kit unsecured inside thepassenger compartment of the vehicleas it may cause injury during a suddenstop or crash. Always store the kit in itsoriginal location.
•After sealant use, the tire pressuremonitoring system sensor and valve stemon the wheel must be replaced by anauthorized Lincoln dealer.
•Operating the kit could cause anelectrical disturbance in radio, CD, andDVD player operation.
* When inflation only is required fora tire or other objects, the selectormust be in the Air position.

Rotating your tires at the recommendedinterval (as indicated in the ScheduledMaintenance chapter) will help your tireswear more evenly, providing better tireperformance and longer tire life.
Front-wheel drive and all-wheel drivevehicles (front tires on the left side ofthe diagram)
All vehicles with directional tires (fronttires on the left of the diagram)
Sometimes irregular tire wear can becorrected by rotating the tires.
USING SUMMER TIRES
Summer tires provide superior performanceon wet and dry roads. Summer tires do nothave the Mud and Snow (M+S or M/S) tiretraction rating on the tire side wall. Sincesummer tires do not have the same tractionperformance as All-season or Snow tires, wedo not recommend using summer tires whentemperatures drop to approximately 45°F(7°C) or below (depending on tire wear andenvironmental conditions) or in snow and ice
conditions. Like any tire, summer tireperformance is affected by tire wear andenvironmental conditions. If you must drivein those conditions, we recommend usingMud and Snow (M+S, M/S), All-season orSnow tires.
Always store your summer tires indoors attemperatures above 19°F (-7°C). The rubbercompounds used in these tires lose flexibilityand may develop surface cracks in the treadarea at temperatures below 19°F (-7°C). If thetires have been subjected to 19°F (-7°C) orless, warm them in a heated space to at least41°F (5°C) for at least 24 hours beforeinstalling them on a vehicle, or moving thevehicle with the tires installed, or checkingtire inflation. Do not place tires near heatersor heating devices used to warm the roomwhere the tires are stored. Do not apply heator blow heated air directly on the tires.Always inspect the tires after storage periodsand before use.
