HOW DOES STABILITY
CONTROL WORK
WARNING: Vehicle modificationsinvolving braking system, aftermarketroof racks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronicstability control system. In addition,installing any stereo speakers mayinterfere with and adversely affect theelectronic stability control system.Reducing the effectiveness of theelectronic stability control system couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
WARNING: Remember that evenadvanced technology cannot defy thelaws of physics. It's always possible tolose control of a vehicle due toinappropriate driver input for theconditions. Aggressive driving on anyroad condition can cause you to losecontrol of your vehicle increasing the riskof personal injury or property damage.Activation of the electronic stabilitycontrol system is an indication that atleast some of the tires have exceededtheir ability to grip the road; this couldreduce the operator's ability to controlthe vehicle potentially resulting in a lossof vehicle control, vehicle rollover,personal injury and death.
If a driving condition activates either thestability control or traction control you mayexperience the following conditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
Electronic stability control enhances yourvehicle’s ability to prevent skids or lateralslides by applying brakes to one or moreof the wheels individually and, if necessary,reducing engine power.
Roll Stability Control
Roll stability control enhances yourvehicle’s ability to prevent rollovers bydetecting your vehicle’s roll motion andthe rate at which it changes by applyingthe brakes to one or more wheelsindividually.
Curve Control
Curve control enhances your vehicle’sability to follow the road when corneringseverely or avoiding objects in the roadway.Curve control operates by reducing enginepower and, if necessary, applying brakesto one or more of the wheels individually.
Side Wind Stabilization
Side wind stabilization is an advancedfeature that works by carefully applyingthe brakes on one side of the vehicle toreduce the effect of a side wind gust onthe vehicle's path.
Traction Control
Traction control enhances your vehicle’sability to maintain traction of the wheelsby detecting and controlling wheel spin.See What Is Traction Control (page 268).

HYDRAULIC POWER
STEERING
HYDRAULIC POWER STEERINGGUIDELINES
To help prevent damage to the powersteering system:
•Do not hold the steering wheel at itsfurthest turning points for more thanthree to five seconds when the engineis running.
•Avoid continuously steering back andforth with elevated engine RPM as thismay overheat the system. If trying tofree a stuck vehicle, pause betweenattempts to allow the power steeringsystem to cool or seek assistance.Typical steering and driving maneuversallow the system to cool.
•Do not operate the vehicle if the powersteering pump fluid level is below theMIN mark on the reservoir.
•Some noise is normal during operation.If excessive, check for low powersteering pump fluid level beforeseeking service by your dealer.
•Heavy or uneven efforts may be causedby low power steering fluid. Check forlow power steering pump fluid levelbefore seeking service by your dealer.
•Do not fill the power steering pumpreservoir above the MAX mark on thereservoir, as this may result in leaksfrom the reservoir.
If the power steering system breaks downor if you switch the engine off, you cansteer the vehicle manually, but it takesmore effort.
If you have any steering componentsserviced or replaced, install new fasteners.Many fasteners have coatings with threadadhesive, or have prevailing torquefeatures you cannot reuse. Do not reuse abolt or nut. Torque fasteners tospecifications.
Steering Tips
If the steering wanders or pulls, check for:
•An improperly inflated tire.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Loose or worn steering components.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds may also make the steeringseem to wander or pull.
Electronic Torque Overlay Steering
(If Equipped)
WARNING: The electric powersteering system has diagnostic checksthat continuously monitor the system. Ifa fault is detected, a message displaysin the information display. Stop yourvehicle as soon as it is safe to do so.Switch the ignition off. After at least 10seconds, switch the ignition on andwatch the information display for asteering system warning message. If asteering system warning messagereturns, have the system checked assoon as possible.
WARNING: If the system detectsan error, you may not feel a difference inthe steering, however a serious conditionmay exist. Have your vehicle checked assoon as possible. Failure to do so mayresult in loss of steering control.

Certain states require functioning trailerbrakes for trailers over a specified weight.Be sure to check state regulations for thisspecified weight.
Ford Motor Company recommendsseparate functioning brake systems fortrailers weighing more than 1,500 lb(680 kg) when loaded.
TOWING A TRAILER
LIMITATIONS
The vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle or trailer.
Note:Your vehicle could havereduced performance whenoperating at high altitudes andwhen heavily loaded or towing a
trailer. When driving at elevation,to match driving performance asperceived at sea level, reduce grossvehicle weight and grosscombination weight by 2% per1,000 ft (300 m) elevation.
LOADING YOUR TRAILER
To help minimize how trailermovement affects your vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest itemscentered between theleft-hand and right-hand sidetrailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to goabove or below 10-15% of theloaded trailer weight. Thetrailer tongue weight shouldnever exceed 10% of themaximum towing capacitywhen towing a conventionaltrailer, and should neverexceed 15% of the maximumtowing capacity when towinga fifth-wheel or goosenecktrailer.
•Select a ball mount with thecorrect rise or drop. When youconnect both the loadedvehicle and trailer, the trailerframe should be level, or
slightly angled down towardyour vehicle, when viewed fromthe side.
TRAILER TOWING HINTS
Towing a trailer places an extra load onyour vehicle's engine, transmission, axle,brakes, tires and suspension. Periodicallyinspect these components during and afterany towing operation.
When driving with a trailer or payload, aslight takeoff vibration or shudder may bepresent due to the increased payloadweight.
