2015 FORD F250 SUPER DUTY warning

transmission may downshift, slow thevehicle and control the vehicle speed whendescending a hill, without the acceleratorpedal being pressed. The amount ofdownshift braking provided will vary basedupon the amount the brake pedal ispressed.
To deactivate the tow/haul feature andreturn to normal driving mode, press thebutton on the end of the gearshift lever.The TOW HAUL light will no longer beilluminated.
When you shut-off and restart the engine,the transmission will automatically returnto normal D (Overdrive) mode (tow/hauloff).
WARNING
Do not use the tow/haul or enginebrake features when driving in icy orslippery conditions as the increasedengine braking can cause the rear wheelsto slide and your vehicle to swing aroundwith the possible loss of vehicle control.
3 (Third)
Transmission starts and operates in thirdgear only
Used for improved traction on slipperyroads. Selecting 3 (Third) provides enginebraking.
2 (Second)
Use 2 (Second) to start-up on slipperyroads or to provide additional enginebraking on downgrades.
1 (First)
•Provides maximum engine braking
•Allows upshifts by moving gearshiftlever
•The transmission will not downshiftinto 1 (First) at high speeds; it willdownshift to a lower gear and thenshift into 1 (First) when the vehiclereaches slower speeds.
Forced downshifts
•Allowed in D (Overdrive) with thetow/haul feature on or off
•Press the accelerator to the floor
•Allows transmission to select anappropriate gear

R (Reverse)
With the gearshift lever in R (Reverse), thevehicle will move backward. Always cometo a complete stop before shifting into andout of R (Reverse).
N (Neutral)
With the gearshift lever in N (Neutral), thevehicle can be started and is free to roll.Hold the brake pedal down while in thisposition.
D (Overdrive) with tow/haul off
D (Overdrive) with tow/haul off is thenormal driving position for the best fueleconomy. The overdrive function allowsautomatic upshifts and downshifts throughgears one through six.
D (Overdrive) with tow/haul on
The tow/haul feature improvestransmission operation when towing atrailer or a heavy load. All transmissiongear ranges are available when usingtow/haul.
To activate tow/haul, press thebutton on the end of thegearshift lever. The TOW HAULindicator light will illuminate in theinstrument cluster.
Tow/haul delays upshifts to reducefrequency of transmission shifting.Tow/haul also provides engine braking inall forward gears when the transmission isin the D (Overdrive) position; this enginebraking will slow the vehicle and assist thedriver in controlling the vehicle whendescending a grade. Depending on drivingconditions and load conditions, thetransmission may downshift, slow thevehicle and control the vehicle speed whendescending a hill, without the acceleratorpedal being pressed. The amount ofdownshift braking provided will vary basedupon the amount the brake pedal ispressed.
Tow/haul may be automatically activated(without pressing the tow/haul button).This provides engine braking to assist thevehicles braking system when goingdownhill and repetitive braking is sensed.Once the tow/haul mode has beenautomatically activated it will notautomatically deactivate.
To deactivate the tow/haul feature andreturn to normal driving mode, press thebutton on the end of the gearshift lever.The TOW HAUL light will no longer beilluminated.
Tow/haul will also deactivate when thevehicle is powered down for a few minutes.
WARNING
Do not use the tow/haul or enginebrake features when driving in icy orslippery conditions as the increasedengine braking can cause the rear wheelsto slide and your vehicle to swing aroundwith the possible loss of vehicle control.

By moving the gearshift lever from the D(Drive) position to the M (Manual) positionyou may now manually select the gear youdesire. Only the current gear will bedisplayed. Press the + button or the –button to upshift or downshift. If the –button is pressed at a vehicle speed that
would cause an engine overspeed, therequested gear will flash then disappearand the transmission will remain in thecurrent gear.
Recommended shift speeds
Upshift according to the following chart:
Upshifts when accelerating (recommended for best fuel economy)
Diesel enginesGasoline enginesShift from:
12 mph (19 km/h)15 mph (24 km/h)1 – 2
19 mph (31 km/h)25 mph (40 km/h)2 – 3
26 mph (42 km/h)40 mph (64 km/h)3 – 4
34 mph (55 km/h)45 mph (72 km/h)4 – 5
46 mph (74 km/h)50 mph (80 km/h)5 – 6
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 the engine willnot be damaged from over-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 ifexcessive engine revving is held withoutshifting.
Automatic Transmission AdaptiveLearning
This feature is designed to increasedurability and provide consistent shift feelover the life of the vehicle. A new vehicleor transmission may have firm shifts, softshifts or both. This operation is considerednormal and will not affect function ordurability of the transmission. Over time,the adaptive learning process will fullyupdate transmission operation.Additionally, whenever the battery isdisconnected or a new battery installed,the strategy must be relearned.

How Your Vehicle Differs FromOther Vehicles
WARNING
Vehicles with a higher center ofgravity such as utility and four-wheeldrive vehicles handle differently thanvehicles with a lower center of gravity.Utility and four-wheel drive vehicles arenot designed for cornering at speeds ashigh as passenger cars any more thanlow-slung sports cars are designed toperform satisfactorily under off-roadconditions. Avoid sharp turns, excessivespeed and abrupt maneuvers in thesevehicles. Failure to drive cautiously couldresult in an increased risk of loss of vehiclecontrol, vehicle rollover, personal injury anddeath.
Truck and utility vehicles can differ fromsome other vehicles. Your vehicle may behigher to allow it to travel over roughterrain without getting hung up ordamaging underbody components.
The differences that make your vehicle soversatile also make it handle differentlythan an ordinary passenger car.
Maintain steering wheel control at alltimes, especially in rough terrain. Sincesudden changes in terrain can result inabrupt steering wheel motion, make sureyou grip the steering wheel from theoutside. Do not grip the spokes.
Drive cautiously to avoid vehicle damagefrom concealed objects such as rocks andstumps.
You should either know the terrain orexamine maps of the area before driving.Map out your route before driving in thearea. To maintain steering and brakingcontrol of your vehicle, you must have allfour wheels on the ground and they mustbe rolling, not sliding or spinning.
Driving Off-Road With Truck andUtility Vehicles
Note:On some models, the initial shift fromtwo-wheel drive to four-wheel drive whilethe vehicle is moving can cause somemomentary clunk and ratcheting sounds.This is the front drivetrain coming up tospeed and the automatic locking hubsengaging and is not cause for concern.
Note:Your vehicle may be equipped witha front air dam that can become damaged(due to reduced ground clearance) whentaking your vehicle off-road. This air damcan be taken off by removing two bolts.
Four-wheel drive vehicles are speciallyequipped for driving on sand, snow, mudand rough terrain and have operatingcharacteristics that are somewhatdifferent from conventional vehicles, bothon and off the road.
Power is supplied to all four wheelsthrough a transfer case. On Four-wheeldrive vehicles, the transfer case allows youto select 4WD when necessary.Information on transfer case operation andshifting procedures can be found in thischapter. Information on transfer casemaintenance can be found in theMaintenance chapter. You should becomethoroughly familiar with this informationbefore you operate your vehicle.
