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 loudspeakers mayinterfere with and adversely affect theelectronic stability control system. Installany aftermarket stereo loudspeaker asfar as possible from the front centerconsole, the tunnel, and the front seatsin order to minimize the risk of interferingwith the electronic stability controlsensors. Reducing the effectiveness ofthe electronic stability control systemcould lead to an increased risk of loss ofvehicle control, vehicle rollover, personalinjury and 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 could
reduce the operator's ability to controlthe vehicle potentially resulting in a lossof vehicle control, vehicle rollover,personal injury and death. If yourelectronic stability control systemactivates, SLOW DOWN.
The system turns on each time you switchthe ignition on.
If a fault occurs in either the stabilitycontrol or the traction control system, thefollowing conditions are possible:
•The stability and traction control lightilluminate.
•The stability control and tractioncontrol systems are not maintainingtraction of the wheels.
If a driving condition activates either thestability control or the traction controlsystem, the following conditions arepossible:
•The stability and traction control lightflash.
•Your vehicle slows down.
•The system reduces 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 could move as the systemapplies higher brake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
The system assists in preventing skids orlateral slides by applying the brakes to oneor more of the wheels individually and, ifnecessary, decreases engine power.

Traction Control
The system helps maintain traction of thewheels by detecting and controlling wheelspin. See Using Traction Control (page151).

•Use a spray with a 40 degree widespray angle pattern.
•Keep the nozzle at a 12 in (305 mm)distance and 90 degree angle to yourvehicle's surface.
Note:Holding the pressure washer nozzleat an angle to the vehicle's surface maydamage graphics and cause the edges topeel away from the vehicle's surface.
Underbody
Regularly clean the entire underside of yourvehicle. This includes the chassis, bodyfloor sheet metal and wheel wells usingfresh water. Keep body and door drainholes free of debris or foreign material.
Under Hood
For removing black rubber marks fromunder the hood we recommend MotorcraftWheel and Tire Cleaner or Motorcraft Bugand Tar Remover.
WAXING
Regular waxing is necessary to protect yourcar's paint from the elements. Werecommend that you wash and wax thepainted surface once or twice a year.
When washing and waxing, park yourvehicle in a shaded area out of directsunlight. Always wash your vehicle beforeapplying wax.
•Use a quality wax that does not containabrasives.
•Follow the manufacturer’s instructionsto apply and remove the wax.
•Apply a small amount of wax in aback-and-forth motion, not in circles.
•Do not allow wax to come in contactwith any non-body (low-gloss black)colored trim. The wax will discolor orstain the parts over time.
•Roof racks.
•Bumpers.
•Grained door handles.
•Side moldings.
•Mirror housings.
•Windshield cowl area.
•Do not apply wax to glass areas.
•After waxing, your car's paint shouldfeel smooth, and be free of streaks andsmudges.
CLEANING THE ENGINE
Engines are more efficient when they areclean because grease and dirt buildup keepthe engine warmer than normal.
When washing:
•Take care when using a power washerto clean the engine. The high-pressurefluid could penetrate the sealed partsand cause damage.
•Do not spray a hot engine with coldwater to avoid cracking the engineblock or other engine components.
•Spray Motorcraft Engine Shampoo andDegreaser on all parts that requirecleaning and pressure rinse clean. InCanada, use Motorcraft EngineShampoo.
Note:If your vehicle has an engine coverremove the cover before application ofMotorcraft Engine Shampoo and Degreaser.Immediately rinse away any over spray.
