PRINCIPLE OF OPERATION
WARNINGS
Hill descent control cannot controldescent in all surface conditions andcircumstances, such as ice orextremely steep grades. Hill descentcontrol is a driver assist system and cannotsubstitute for good judgment by the driver.Failure to do so may result in loss of vehiclecontrol, crash or serious injury.
Hill descent control does not providehill hold at zero miles per hour (0kilometers per hour). When stopped,the parking brake must be applied or thevehicle must be placed in P (Park) or itmay roll away.
Hill descent control allows the driver to setand maintain vehicle speed whiledescending steep grades in various surfaceconditions.
Hill descent control can maintain vehiclespeeds on downhill grades between 2 mph(3 km/h) and 12 mph (20 km/h). Above 20mph (32 km/h), the system remainsarmed, but descent speed cannot be setor maintained.
Hill descent control requires a coolingdown interval after a period of sustaineduse. The amount of time that the featurecan remain active before cooling varieswith conditions. The system will provide awarning in the message center and a chimewill sound when the system is about todisengage for cooling. At this time,manually apply the brakes as needed tomaintain descent speed.
USING HILL DESCENT
CONTROL
1.Press and release the hill descentbutton located on the center console.Switching on this feature will light thebutton and sound a tone.
2.Press the accelerator pedal to increasedescent speed until you have reachedthe desired speed.
3.Press the brake pedal to decreasedescent speed until you have reachedthe desired speed.
Note:Once you have reached the desireddescent speed, remove your feet from thepedals to maintain the chosen vehiclespeed.
See the Information Displays chapter ofyour Owner’s Manual for hill descentmode messages.

Driving in Deep Snow
•Maintain vehicle momentum.
•Apply the throttle very gently to avoidspinning the tires. Spinning the tires willpotentially dig the vehicle deeper intothe snow.
•Drive in a controlled manner, avoidingaggressive steering wheel movements,and keep braking to a minimum.
•Extremely deep snow may cause thevehicle to high center causing thevehicle to become stuck. Test thedepth of the snow before trying to drivethrough it.
Crossing Obstacles
•Review the path ahead beforeattempting to cross any obstacle. It isbest if the obstacle is reviewed fromoutside the vehicle so that there is agood understanding of terrain conditionboth in, front of, and behind theobstacle.
•Approach obstacles slowly and slowlyinch the vehicle over.
•If a large obstacle such as a rockcannot be avoided, choose a path thatplaces the rock directly under the tirerather than the undercarriage of thevehicle. This will help prevent damageto the vehicle.
•Ditches and washouts should becrossed at a 45 degree angle, allowingeach wheel to independently cross theobstacle.
Hill Climbing
WARNING
Extreme care should be used whensteering the vehicle in reverse downa slope so as not to cause the vehicleto swerve out of control.
•Always attempt to climb a steep hillalong the fall line of the slope and notdiagonally.
•If the vehicle is unable to make it upthe hill, DO NOT attempt to turn backdown the slope. Place the vehicle inlow range and slowly back down inreverse.
•When descending a steep slope, selectlow gear and engage hill descentcontrol. Use the throttle and brakepedals to control your descent speedas described earlier in this section usinghill descent control. Note that hilldescent control is functional in reverseand should be used in this situation.
Water Wading
Your vehicle is designed to operate in waterdepths up to 30 inches (760 millimeters).However, as the water depth increases,vehicle speed must be reduced to avoidpotential vehicle damage.
•Always determine the depth beforeattempting a water crossing.
•Proceed slowly and avoid splashingwater any more than is necessary.
•Be aware that obstacles and debrismay be beneath the water’s surface.
•Keep the doors fully closed during thewater crossing.
•Upon completion of the water crossing,slowly drive a short distance and checkthe brakes for full effectiveness.
Refer to chart below for the maximumallowable speeds when driving throughwater.
Note:Failure to follow the recommendedspeeds may result in vehicle damage.
21F150 (TF6)Driving Hints

•
•It is highly encouraged that you switchto off-road mode and perform anAdvanceTrac single press to make sureimproved off-road brakingperformance under these conditions.Be sure to disengage the off-roadmode and switch back to AdvanceTrackey-on mode before performing anystreet driving. Please see the Off-RoadMode section of this supplement formore details.
After Off-Road Driving
It is important to complete a full vehicleinspection after off-road driving. Someitems to check include:
•Make sure that tires are inflated toproper tire pressure as indicated on thetire placard.
•Check the wheels and undercarriagefor built up mud or debris which cancause vehicle vibration.
•Make sure that the grille and radiatorare clear of any obstructions that mayaffect cooling.
•Make sure that the brakes are in properworking order and free of any mud,stones and debris, which can becometrapped around the brake rotor,backing plate and caliper.
•Check that the air filter is clean and dry.
•Inspect for torn or punctured boots onball joints, half shafts, steering gears.
•Inspect exhaust system for damage orlooseness.
•Inspect undercarriage fasteners. If anyare loose or damaged, tighten orreplace ensuring that the proper torquespecification is used.
•Inspect the tires for any cuts in thetread or sidewall area. Also inspect thesidewall for any bulge indicatingdamage to the tire.
•Inspect the wheels for dents, cracks,or other damage.
