In order to prevent the engine from runningat too low an RPM, which may cause it tostall, SelectShift will still automaticallymake some downshifts if it has determinedthat you have not downshifted in time.Although SelectShift will make somedownshifts for you, it will still allow you todownshift at any time as long as theSelectShift determines that damage willnot be caused to the engine fromover-revving.
SelectShift will not automatically upshift,even if the engine is approaching the RPMlimit. It must be shifted manually bypressing the + button.
Note:Engine damage may occur if youmaintain excessive engine revving withoutshifting.
The SelectShift Automatic transmissionfeature has two modes: PRS and M mode.
PRS (Progressive Range Selection)
Progressive Range Selection gives you theability to lockout gears from the automaticshifting range. This may provide you withan improved driving experience (forexample, in slippery conditions or whenexperiencing a steep grade).
With the gearshift lever in drive (D), pressthe – button to active PRS. The availableand selected gears are indicated on theinstrument cluster.
All available gears will display with thecurrent gear indicated. Press the – buttonagain to lock out gears beginning with thehighest gear. Example: press the – buttontwice to lock out 6th and 5th gears. Onlythe available gears will display and thetransmission will automatically shiftbetween the available gears. Press the +button to unlock gears to allow thetransmission to shift to higher gears. Thetransmission will shift automatically withinthe gear range you select.
Manual (M)
Moving the gearshift lever to the manual(M) position will allow you to manuallyselect the gear you desire. Only the currentgear will display. Use the buttons on thegearshift lever to manually select gears.Press the + button to upshift or the –button to downshift. Return thetransmission to a different gearshiftposition to deactivate manual control.

Automatic Transmission AdaptiveLearning
This feature's design is to increasedurability and provide consistent shift feelover the life of your vehicle. A new vehicleor transmission may have firm shifts, softshifts or both. This operation is normal anddoes not affect function or durability of thetransmission. Over time, the adaptivelearning process fully updates transmissionoperation. Additionally, whenever youdisconnect the battery or install a newbattery, the system must relearn thestrategy.
Brake-Shift Interlock
WARNINGS
Do not drive your vehicle until youverify that the brake lamps areworking.
When doing this procedure, you needto take the transmission out of park(P) which means your vehicle canroll freely. To avoid unwanted vehiclemovement, always fully apply the parkingbrake prior to doing this procedure. Usewheels chocks if appropriate.
If the parking brake is fully released,but the brake warning lamp remainsilluminated, the brakes may not beworking properly. Have your vehiclechecked as soon as possible.
Your vehicle is equipped with a brake-shiftinterlock feature that prevents thegearshift lever from moving from park (P)when the ignition is on and the brake pedalis not pressed.
If you cannot move the gearshift lever outof park (P) position with the ignition is onand the brake pedal pressed, a malfunctionmay have occurred. It is possible that afuse has blown or your vehicle’s brakelamps are not operating properly. SeeFuse Specification Chart (page 312).
If the fuse is not blown and the brakelamps are working properly, the followingprocedure allows you to move the gearshiftlever from park (P):
1. Apply the parking brake. Switch theignition key to 1 (off), then remove thekey.
2. Move the steering column to the fulldown and full rearward position(toward the driver’s seat).
3. Remove the gearshift lever boot.
4. Place fingers into hole where youremoved the gearshift lever boot andpull top half of shroud up and forwardto separate it from the lower half of theshroud. There is a hinge at the forwardedge of the top shroud. Roll the tophalf of the shroud upward on the hingepoint to clear the hazard flasher button,then pull straight rearward toward thedriver’s seat to remove.
5. Remove the top half of the shroud.
6. Remove the three fasteners under thecolumn that secure the lower shroudhalf to the column.
7.Pull the lock lever into the full unlockedposition and remove the lower shroudcover by pulling the lever handlethrough the slot in the cover.

The system uses radar sensors that arelocated inside the tail lamp on each sideof your vehicle. Any dirt, mud and snow infront of the sensors or driving in heavy raincan cause system degradation. Also, othertypes of obstructions in front of the sensorcan cause system degradation. This isreferred to as a ‘blocked’ condition.
Note:Do not apply bumper stickers and/orrepair compound to these areas, this cancause degraded system performance.
If the system detects a degradedperformance condition, a message warningappears in the display screen. The alertindicators remain ON and the system willno longer provides any warnings. You canclear the warning but the alert indicatorsremain illuminated.
A "blocked" condition can be cleared intwo ways:
•After the blockage in front of thesensors is removed or therainfall/snowfall rate decreases orstops, drive for a few minutes in trafficto allow the sensors to detect passingvehicles.
•By cycling the ignition from ON to OFFand then back ON.
Note:If your vehicle has a tow bar with afactory equipped trailer tow module and itis towing a trailer, the sensors willautomatically turn the Blind SpotInformation System off. If your vehicle hasa tow bar but no factory equipped trailertow module, it is recommended to turn theBlind Spot Information System offmanually. Operating the Blind SpotInformation System without the Blind SpotTrailer Tow package and a trailer attachedwill cause poor system performance.
Blind Spot Information Systemwith Trailer Tow (If Equipped)
The Blind Spot Information System withTrailer Tow is designed to aid you indetecting vehicles that may have enteredthe detection area zone (A). The detectionarea is on both sides of your vehicle andtrailer, extending rearward from theexterior mirrors to the end of your trailer.
When a trailer is attached and thecustomer has set up a Blind Spot Trailer,the Blind Spot Information System withTrailer Tow becomes active when drivingforward above 6 mph (10 km/h). SeeTrailer Reversing Aids (page 269).
The Blind Spot Information System withTrailer Tow can be turned off in theinstrument cluster. If the Blind SpotInformation System is turned off, then theBlind Spot Information System with TrailerTow automatically turns off.

Once the trailer is level or slightly nosedown toward the vehicle:
•Lock the bar tension adjuster in place.
•Check that the trailer tongue securelyattaches and locks onto the hitch.
•Install safety chains, lighting, and trailerbrake controls as required by law or thetrailer manufacturer.
Fifth-wheel Trailer Hitch (If Equipped)
Note:The mounting pads in the bed arespecifically designed for certain fifth-wheeltrailer hitches and gooseneck ball hitches.Do not use these mounting pads for otherpurposes.
Note:Contact an authorized dealer topurchase gooseneck and fifth-wheel hitchesthat are compatible with your vehicle.
Your vehicle may be equipped with afifth-wheel prep package. This packageenables your vehicle to accept certainfifth-wheel trailer hitches and gooseneckball hitches. The fifth-wheel trailer hitchattaches to the four mounting pads in thepick-up bed. An optional 7-pin trailer wiringconnector may be in the bed as well. Thegooseneck ball hitch is a separatemounting pad from the fifth-wheel hitch,located in the center of the bed.
Shorter pick-up boxes, such as the 6½-footbox on the F-250 and F-350, provide lessclearance between the cab and thefifth-wheel and gooseneck trailercompared to longer box pick-ups, such asan 8-foot box on the F-250 or F-350. Whenselecting a trailer and tow vehicle, it iscritical to check that this combinationprovides clearance between the front ofthe trailer and tow vehicle for turns up to90 degrees. Failure to follow this
recommendation could result in the trailercontacting the cab of the tow vehicleduring tight turns that are typical duringlow-speed parking and turning maneuvers.This contact could result in damage to thetrailer and tow vehicle.
Safety Chains
Note:Do not attach safety chains to thebumper.
Always connect the safety chains to theframe or hook retainers of your vehiclehitch.
To connect the safety chains, cross thechains under the trailer tongue and allowenough slack for turning tight corners. Donot allow the chains to drag on the ground.
Trailer Brakes
WARNING
Do not connect a trailer's hydraulicbrake system directly to yourvehicle's brake system. Your vehiclemay not have enough braking power andyour chances of having a collision greatlyincrease.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if youinstall them properly and adjust them tothe manufacturer's specifications. Thetrailer brakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.
Separate functioning brake systemsare required for safe control of towedvehicles and trailers weighing morethan 1500 pounds (680 kilograms)when loaded.
