2018 LINCOLN NAVIGATOR tires

If your vehicle goes from one type of surfaceto another (i.e. from concrete to gravel) theremay be a change in the way your vehicleresponds 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 slowly andavoid excessive wheel slip.
Avoid driving at excessive speeds, thiscauses vehicle momentum to work againstyou and your vehicle could become stuck tothe point that assistance may be requiredfrom another vehicle. Remember, you maybe able to back out the way you came if youproceed 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 may belimited.
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 when moving slowly.
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even 4X4 vehicles can lose traction inslick 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.
If the transmission, transfer case or front axleare submerged in water, their fluids shouldbe checked and changed, if necessary.
If the front or rear axle is submerged in water,the axle lubricant should be replaced.
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.
Driving on Hilly or Sloping Terrain
Note:Avoid driving crosswise or turning onsteep slopes or hills.
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 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 your vehicle stalls, do not try to turn aroundbecause this could cause vehicle roll over.It is better to reverse back to a safe location.
Apply just enough power to the wheels toclimb the hill. Too much power causes 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. Disengage overdriveor move the transmission selector lever to alower gear. When descending a steep hill,avoid sudden hard braking as you could losecontrol. The front wheels have to be turningin order to steer your vehicle.
If your vehicle has anti-lock brakes, apply thebrakes steadily. Do not pump the brakes.
Driving on Snow and Ice
WARNING: If you are driving inslippery conditions that require tire chainsor cables, 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 endof your vehicle slides while cornering, steerin the direction of the slide until you regaincontrol of your vehicle.
Note:Excessive tire slippage can causetransmission damage.
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 when 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 and ice.Apply the accelerator slowly and steadilywhen starting from a full stop.
Avoid sudden braking. Although a four-wheeldrive vehicle may accelerate better than atwo-wheel drive vehicle in snow and ice, itdoes not stop any faster as braking occursat all four wheels. Do not becomeoverconfident in any road condition.
Make sure you allow sufficient distancebetween you and other vehicles for stopping.Drive slower than usual and consider usingone of the lower gears. In emergencystopping situations, apply the brake steadily.Do not pump the brake pedal. See Hints onDriving With Anti-Lock Brakes (page 226).

PRINCIPLE OF OPERATION
WARNING: Vehicle modificationsinvolving braking system, aftermarket roofracks, suspension, steering system, tireconstruction and wheel and tire size maychange the handling characteristics of yourvehicle and may adversely affect theperformance 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.
WARNING: Remember that evenadvanced technology cannot defy the lawsof physics. 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 theroad; this could reduce the operator’sability to control the vehicle potentiallyresulting in a loss of vehicle control, vehiclerollover, personal injury and death. If yourelectronic stability control system activates,SLOW DOWN.
The system automatically turns on each timeyou switch the ignition on.
If a fault occurs in either the stability controlor the traction control system, you mayexperience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and traction controlsystems do not enhance your vehicle'sability to maintain traction of the wheels.
If a driving condition activates either thestability control or the traction control systemyou may experience the following conditions:
•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 and yourfoot is not on the brake, the brake pedalmay move as the system applies higherbrake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:

Note:Do not clean the sensors with sharpobjects.
Note:The sensors may not detect objectswith surfaces that absorb ultrasonic waves.The sensors may falsely detect objects dueto ultrasonic interference caused bymotorcycle exhausts, truck air brakes orhorns, for example.
Note:If you change any tires, the systemmust recalibrate and may not correctlyoperate for a short time.
The system may not correctly operate in anyof the following conditions:
•You use a spare tire or a tire that issignificantly worn more than the othertires.
•One or more tires are incorrectly inflated.
•You try to park on a tight curve.
•Something passes between the frontbumper and the parking space. Forexample, a pedestrian or cyclist.
•The edge of the neighboring parkedvehicle is high off the ground. Forexample, a bus, tow truck or flatbedtruck.
•The weather conditions are poor. Forexample, during heavy rain, snow, fog,high humidity and high temperatures.
Do not use the system if:
•You have attached an add-on accessoryclose to the sensors on the front or rearof your vehicle. For example, a bike rackor trailer.

Automatic parking brake application andcancellation occurs if:
•You unbuckle the seatbelt and open thedoor after you stop the vehicle.
•You hold the vehicle at a stopcontinuously for more than three minutes.
Hilly Condition and Trailer Tow Usage
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.
Note:When towing with adaptive cruisecontrol, switch on Tow/Haul Mode.
Note:Tow/Haul mode increases the timegaps and allows more distance for braking.
Select a lower gear when the system isactive in situations such as prolongeddownhill driving on steep grades, forexample in mountainous areas. The systemneeds additional engine braking in thesesituations to reduce the load on the vehicle’sregular brake system to prevent it fromoverheating.
Switching Adaptive Cruise Control Off
Note:You erase the set speed and gapsetting when you switch the system off.
Press OFF when the system is in standbymode, or switch the ignition off.

operation at Gross Vehicle WeightRating, not at Gross Combined WeightRating.) Separate functional brakesshould be used for safe control of towedvehicles and for trailers where the GrossCombined Weight of the towing vehicleplus the trailer exceed the Gross VehicleWeight Rating of the towing vehicle.
The gross combined weight must neverexceed the Gross Combined WeightRating.
Note: For trailer towing informationrefer to the RV and Trailer Towing Guideavailable at an authorized dealer.
WARNING: Do not exceed theGVWR or the GAWR specified on thecertification label.
WARNING: Do not usereplacement tires with lower loadcarrying capacities than the originaltires because they may lower yourvehicle's GVWR and GAWR limitations.Replacement tires with a higher limitthan the original tires do not increasethe GVWR and GAWR limitations.
WARNING: Exceeding anyvehicle weight rating can adverselyaffect the performance and handlingof your vehicle, cause vehicle damageand can result in the loss of control ofyour vehicle, serious personal injuryor death.
Steps for determining the correct loadlimit:
1.Locate the statement "The combinedweight of occupants and cargoshould never exceed XXX kg or XXXlb." on your vehicle’s placard.
2.Determine the combined weight ofthe driver and passengers that willbe riding in your vehicle.
3.Subtract the combined weight of thedriver and passengers from XXX kgor XXX lb.
4. The resulting figure equals theavailable amount of cargo andluggage load capacity. For example,if the “XXX” amount equals 1,400 lb.and there will be five 150 lb.passengers in your vehicle, theamount of available cargo andluggage load capacity is 650 lb.(1400-750 (5 x 150) = 650 lb.)
5.Determine the combined weight ofluggage and cargo being loaded onthe vehicle. That weight may not
safely exceed the available cargoand luggage load capacity calculatedin Step 4.
