VEHICLE STORAGE
If you plan on storing your vehicle for 30days or more, read the followingmaintenance recommendations to make sureyour vehicle stays in good operatingcondition.
We engineer and test all motor vehicles andtheir components for reliable, regular driving.Under various conditions, long-term storagemay lead to degraded engine performanceor failure unless you use specific precautionsto preserve engine components.
General
•Store all vehicles in a dry, ventilatedplace.
•Protect from sunlight, if possible.
•If vehicles are stored outside, theyrequire regular maintenance to protectagainst rust and damage.
Body
•Wash your vehicle thoroughly to removedirt, grease, oil, tar or mud from exteriorsurfaces, rear-wheel housing and theunderside of front fenders.
•Periodically wash your vehicle if it isstored in exposed locations.
•Touch-up exposed or primed metal toprevent rust.
•Cover chrome and stainless steel partswith a thick coat of auto wax to preventdiscoloration. Re-wax as necessary whenyou wash your vehicle.

Vehicle Care

GENERAL INFORMATION
Use only approved wheel and tire sizes,using other sizes could damage your vehicle.If you change the diameter of the tires fromthat fitted at the factory, the speedometermay not display the correct speed. If youintend to change the size of the wheels fromthat fitted by the manufacturer, you cancheck the suitability with an authorizeddealer.
Additional information related to thefunctionality and maintenance of your tirescan be found later in this chapter. See TireCare (page 394).
You can find the recommended tire inflationpressures can on the Tire Label, which is onthe B-pillar or the edge of the driver door.You can also find this information on theSafety Compliance Certification Label, affixedto either the door hinge pillar, door-latchpost, or the door edge that meets the doorlatch post; next to the driver seating position.
We strongly recommend maintaining thesetire pressures at all times. Failure to followthe tire pressure recommendations cancause uneven treadwear patterns, reducedfuel economy, and adversely affect the wayyour vehicle handles.
Note:Check and set the tire pressure at theambient temperature in which you areintending to drive your vehicle and when thetires are cold.
Note:Check your tire pressures at least onceper month.
If your vehicle has a spare tire, set thepressure to the highest value given for yourvehicle and tire size combination.
Notice to utility vehicle and truckowners
WARNING: Utility vehicles have asignificantly higher rollover rate than othertypes of vehicles.
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.
WARNING: In a rollover crash, anunbelted person is significantly more likelyto die than a person wearing a seatbelt.
WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheel drivevehicle may accelerate better than atwo-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always drive ata safe speed.

Utility vehicles and trucks handle differentlythan passenger cars in the various drivingconditions that are encountered on streets,highways and off-road. Utility vehicles andtrucks are not designed for cornering atspeeds as high as passenger cars any morethan low-slung sports cars are designed toperform satisfactorily under off-roadconditions.
Study your owner's manual and anysupplements for specific information aboutequipment features, instructions for safedriving and additional precautions to reducethe risk of an accident or serious injury.
Four-wheel drive system (If Equipped)
WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheel drivevehicle may accelerate better than atwo-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always drive ata safe speed.
A vehicle equipped with four-wheel drive,when selected, has the ability to use all fourwheels to power itself. This increases tractionwhich may enable you to safely drive overterrain and road conditions that aconventional two-wheel drive vehicle cannot.
Power is supplied to all four wheels througha transfer case or power transfer unit.Four-wheel drive vehicles allow you to selectdifferent modes as necessary. Forinformation on transfer case operation andshifting procedures, See Four-Wheel Drive(page 216). For information on transfer casemaintenance, See Maintenance (page 361).You should become thoroughly familiar withthis information before you operate yourvehicle.
On some four-wheel drive vehicles, the initialshift from two-wheel to four-wheel drivewhen the vehicle is moving can cause amomentary clunk and ratcheting sound.These sounds are normal and are not causefor concern.
In four-wheel drive vehicles, the size of thespare tire relative to the remaining tires canhave an effect on the 4x4 system. If there isa significant difference between the size ofa spare and the remaining tires, four-wheeldrive functionality may be limited. See UsingFour-Wheel Drive (page 216).
How your vehicle differs from othervehicles
Sport utility vehicles and trucks can differfrom some other vehicles in a few noticeableways. Your vehicle may be:

Wheels and Tires

Improper or inadequate vehiclemaintenance can cause tires to wearabnormally. Inspect all your tires,including the spare, frequently, andreplace them if one or more of thefollowing conditions exist:
Tire Wear
When the tread is worn down to onesixteenth of an inch (2 millimeters), tiresmust be replaced to help prevent yourvehicle from skidding and hydroplaning.Built-in treadwear indicators, or wearbars, which look like narrow strips ofsmooth rubber across the tread willappear on the tire when the tread isworn down to one sixteenth of an inch(2 millimeters).
When the tire tread wears down to thesame height as these wear bars, the tireis worn out and must be replaced.
Damage
Periodically inspect the tire treads andsidewalls for damage (such as bulges inthe tread or sidewalls, cracks in the
tread groove and separation in the treador sidewall). If damage is observed orsuspected have the tire inspected by atire professional. Tires can be damagedduring off-road use, so inspection afteroff-road use is also recommended.
Age
WARNING: Tires degrade overtime depending on many factors suchas weather, storage conditions, andconditions of use (load, speed, inflationpressure) the tires experiencethroughout their lives.
WARNING: In general, tiresshould be replaced after six yearsregardless of tread wear. However,heat caused by hot climates orfrequent high loading conditions canaccelerate the aging process and mayrequire tires to be replaced morefrequently.
WARNING: You should replaceyour spare tire when you replace theroad tires or after six years due toaging even if it has not been used.

Note:Your vehicle may be equippedwith a dissimilar spare wheel and tireassembly. A dissimilar spare wheel andtire assembly is defined as a sparewheel and tire assembly that is differentin brand, size or appearance from theroad tires and wheels. If you have adissimilar spare wheel and tire assemblyit is intended for temporary use only andshould not be used in a tire rotation.
Note:After having your tires rotated,inflation pressure must be checked andadjusted to the vehicle requirements.
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.
Rear-wheel drive vehicles andfour-wheel drive vehicles (front tires atleft of diagram)
Sometimes irregular tire wear can becorrected by rotating the tires.
USING SNOW CHAINS
WARNING: Snow tires must be thesame size, load index and speed rating asthose originally provided by Ford. Use ofany tire or wheel not recommended byFord can affect the safety and performanceof your vehicle, which could result in anincreased risk of loss of control, vehiclerollover, personal injury and death.Additionally, the use of non-recommended
tires and wheels can cause steering,suspension, axle, transfer case or powertransfer unit failure. Follow the Fordrecommended tire inflation pressure foundon the Safety Compliance CertificationLabel (on the door hinge pillar, door latchpost or the door edge that meets the doorlatch post, next to the driver seat), or TireLabel on the B-Pillar or the edge of thedriver door. Failure to follow the tirepressure recommendations can causeuneven treadwear patterns and adverselyaffect the way your vehicle handles.
Note:The suspension insulation andbumpers will help prevent vehicle damage.Do not remove these components from yourvehicle when using snow tires and chains.
The tires on your vehicle have all-weathertreads to provide traction in rain and snow.However, in some climates, you may needto use snow tires and cables. If you need touse cables, it is recommended that steelwheels (of the same size and specifications)be used, as cables may chip aluminumwheels.

Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommended by thevehicle manufacturer on the vehicle placardor tire inflation pressure label. (If your vehiclehas tires of a different size than the sizeindicated on the vehicle placard or tireinflation pressure label, you shoulddetermine the proper tire inflation pressurefor those tires).
As an added safety feature, your vehicle hasbeen equipped with a Tire PressureMonitoring System (TPMS) that illuminates alow tire pressure telltale when one or moreof your tires is significantly under-inflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop andcheck your tires as soon as possible, andinflate them to the proper pressure. Drivingon a significantly under-inflated tire causesthe tire to overheat and can lead to tirefailure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitutefor proper tire maintenance, and it is thedriver’s responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination ofthe TPMS low tire pressure telltale.
Your vehicle has also been equipped with aTPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When thesystem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists.
When the malfunction indicator is illuminated,the system may not be able to detect orsignal low tire pressure as intended. TPMSmalfunctions may occur for a variety ofreasons, including the installation ofreplacement or alternate tires or wheels onthe vehicle that prevent the TPMS from
functioning properly. Always check the TPMSmalfunction telltale after replacing one ormore tires or wheels on your vehicle toensure that the replacement or alternate tiresand wheels allow the TPMS to continue tofunction properly.
