traction control FORD F450 SUPER DUTY 2017 User Guide

PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL
WARNING
The stability and traction controllight illuminates steadily if thesystem detects a failure. Make sureyou did not manually disable the tractioncontrol system using the informationdisplay controls or the switch. If thestability control and traction control lightis still illuminating steadily, have thesystem serviced by an authorized dealerimmediately. Operating your vehicle withthe traction control disabled could lead toan increased risk of loss of vehicle control,vehicle rollover, personal injury and death.
The system automatically turns on eachtime you switch the ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Note:When you switch traction control off,stability control remains fully active.
Note:For additional information on thetraction and stability control systems. SeeUsing Stability Control (page 227).
Switching the System Off
When you switch the system off or on, amessage appears in the informationdisplay showing system status.
Use the traction and stability controlswitch on the instrument panel to switchthe system off or on.
The switch illuminates when tractioncontrol is off.
When you place your vehicle intofour-wheel drive low mode the tractioncontrol disables. Traction control resumesfull operation when you put your vehicleback into two-wheel drive mode.

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involvingbraking system, aftermarket roofracks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance 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.
Remember that even advancedtechnology cannot defy the laws ofphysics. 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 the road;this could reduce the operator’s ability tocontrol the vehicle potentially resulting ina loss of vehicle control, vehicle rollover,personal injury and death. If your electronicstability control system activates, SLOWDOWN.
The system automatically turns on eachtime you switch the ignition on.
If a fault occurs in either the stabilitycontrol or the traction control system, youmay experience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and tractioncontrol systems do not enhance yourvehicle's ability to maintain traction ofthe wheels.
•The Adaptive Steering system (ifequipped) automatically changes thesteering function to a fixed steeringratio. See Steering (page 256).
If a driving condition activates either thestability control or the traction controlsystem you may experience the followingconditions:
•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 andyour foot is not on the brake, the brakepedal may move as the system applieshigher brake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
The system enhances your vehicle’s abilityto prevent skids or lateral slides byapplying brakes to one or more of thewheels individually and, if necessary,reducing engine power.

•Driving on flat terrain offers improvedfuel economy as compared to drivingon hilly terrain.
•Transmissions give their best fueleconomy when operated in the topcruise gear and with steady pressureon the gas pedal.
•Four-wheel-drive operation (ifequipped) is less fuel efficient thantwo-wheel-drive operation.
•Close the windows for high-speeddriving.
DRIVING THROUGH WATER
WARNING
Do not drive through flowing or deepwater as you may lose control of yourvehicle.
Note:Driving through standing water cancause vehicle damage.
Note:Engine damage can occur if waterenters the air filter.
Before driving through standing water,check the depth. Never drive through waterthat is higher than the bottom of the wheelhubs.
When driving through standing water, drivevery slowly and do not stop your vehicle.Your brake performance and traction maybe limited. After driving through water andas soon as it is safe to do so:
•Lightly press the brake pedal to dry thebrakes and to check that they work.
•Check that the horn works.
•Check that the exterior lights work.
•Turn the steering wheel to check thatthe steering power assist works.
FLOOR MATS
WARNINGS
Always use floor mats that aredesigned to fit the foot well of yourvehicle. Only use floor mats thatleave the pedal area unobstructed. Onlyuse floor mats that are firmly secured toretention posts so that they cannot slip outof position and interfere with the pedalsor impair safe operation of your vehicle inother ways.
Pedals that cannot move freely cancause loss of vehicle control andincrease the risk of serious personalinjury.
Always make sure that the floormats are properly attached to theretention posts in the carpet that aresupplied with your vehicle. Floor mats mustbe properly secured to both retention poststo make sure mats do not shift out ofposition.
Never place floor mats or any othercovering in the vehicle foot well thatcannot be properly secured toprevent them from moving and interferingwith the pedals or the ability to control thevehicle.

TIRE CARE
Information About UniformTire Quality Grading
Tire Quality Grades apply to newpneumatic passenger car tires.The Quality grades can be foundwhere applicable on the tiresidewall between tread shoulderand maximum section width. Forexample: Treadwear 200Traction AA Temperature A.
These Tire Quality Grades aredetermined by standards that theUnited States Department ofTransportation has set.
Tire Quality Grades apply to newpneumatic passenger car tires.They do not apply to deep tread,winter-type snow tires,space-saver or temporary usespare tires, light truck or LT typetires, tires with nominal rimdiameters of 10 to 12 inches orlimited production tires as definedin Title 49 Code of FederalRegulations Part 575.104 ©)(2).
U.S. Department ofTransportation Tire qualitygrades: The U.S. Department ofTransportation requires FordMotor Company to give you thefollowing information about tiregrades exactly as the governmenthas written it.
Treadwear
The treadwear grade is acomparative rating based on thewear rate of the tire when testedunder controlled conditions on aspecified government test course.For example, a tire graded 150would wear one and one-half (1½) times as well on thegovernment course as a tiregraded 100. The relativeperformance of tires depends
upon the actual conditions of theiruse, however, and may departsignificantly from the norm due tovariations in driving habits, servicepractices, and differences in roadcharacteristics and climate.
Traction AA A B C
WARNING
The traction grade assignedto this tire is based onstraight-ahead braking tractiontests, and does not includeacceleration, cornering,hydroplaning or peak tractioncharacteristics.

The traction grades, from highestto lowest are AA, A, B, and C. Thegrades represent the tire’s abilityto stop on wet pavement asmeasured under controlledconditions on specifiedgovernment test surfaces ofasphalt and concrete. A tiremarked C may have poor tractionperformance.
Temperature A B C
WARNING
The temperature grade forthis tire is established for atire that is properly inflated andnot overloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heat
buildup and possible tire failure.
The temperature grades are A(the highest), B and C,representing the tire’s resistanceto the generation of heat and itsability to dissipate heat whentested under controlled conditionson a specified indoor laboratorytest wheel. Sustained hightemperature can cause thematerial of the tire to degenerateand reduce tire life, and excessivetemperature can lead to suddentire failure. The grade Ccorresponds to a level ofperformance which all passengercar tires must meet under the
Federal Motor Vehicle SafetyStandard No. 139. Grades B and Arepresent higher levels ofperformance on the laboratorytest wheel than the minimumrequired by law.
Glossary of Tire Terminology
*Tire label: A label showing theoriginal equipment tire sizes,recommended inflation pressureand the maximum weight thevehicle can carry.
*Tire Identification Number(TIN): A number on the sidewallof each tire providing informationabout the tire brand andmanufacturing plant, tire size anddate of manufacture. Also referredto as DOT code.
*Inflation pressure: A measureof the amount of air in a tire.
*Standard load: A class ofP-metric or Metric tires designedto carry a maximum load at setpressure. For example: ForP-metric tires 35 psi (2.4 bar) andfor Metric tires 36 psi (2.5 bar).Increasing the inflation pressurebeyond this pressure will notincrease the tire’s load carryingcapability.
*Extra load: A class of P-metricor Metric tires designed to carry aheavier maximum load at 42 psi(2.9 bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s loadcarrying capability.

USING SNOW CHAINS
WARNING
Snow tires must be the same size,load index, speed rating as thoseoriginally provided by Ford. Use ofany tire or wheel not recommended byFord can affect the safety andperformance of your vehicle, which couldresult in an increased risk of loss of vehiclecontrol, vehicle rollover, personal injury anddeath. Additionally, the use ofnon-recommended tires and wheels couldcause steering, suspension, axle, transfercase or power transfer unit failure.
Note:Do not use snow chains on vehicleswith 20 inch wheels and tires.
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 needto use cables, it is recommended that steelwheels (of the same size andspecifications) be used, as cables may chipaluminum wheels.
Note:The suspension insulation andbumpers will help prevent vehicle damage.Do not remove these components from yourvehicle when using snow tires and chains.
Follow these guidelines when using snowtires and chains:
•If possible, avoid fully loading yourvehicle
•Use only SAE Class S chains.
•Install chains securely, verifying thatthe chains do not touch any wiring,brake lines or fuel lines.
•Drive cautiously. If you hear the chainsrub or bang against your vehicle, stopand retighten the chains. If this doesnot work, remove the chains to preventdamage to your vehicle.
•Remove the tire chains when they areno longer needed. Do not use tirechains on dry roads.
If you have any questions regarding snowchains or cables, please contact yourauthorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
Vehicle Tire Pressure MonitoringSystem
WARNING
The tire pressure monitoring systemis not a substitute for manuallychecking tire pressures. You shouldperiodically check tire pressures using apressure gauge. Failure to correctlymaintain tire pressures could increase therisk of tire failure, loss of control, vehiclerollover and personal injury.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflatedto the inflation pressure recommended bythe vehicle manufacturer on the vehicleplacard or tire inflation pressure label. (Ifyour vehicle has tires of a different sizethan the size indicated on the vehicleplacard or tire inflation pressure label, youshould determine the proper tire inflationpressure for those tires.)
