Mud and Water
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even four-wheel drive vehicles canlose traction in slick mud. If your vehicledoes slide, steer in the direction of the slideuntil you regain control of your vehicle.
After driving through mud, clean off residuestuck to rotating driveshafts and tires.Excess mud stuck on tires and rotatingdriveshafts can cause an imbalance thatcould damage drive components.
Water
If you must drive through high water, driveslowly. Traction or brake capability maybe limited.
When driving through water, determine thedepth and avoid water higher than thebottom of the hubs. If the ignition systemgets wet, your vehicle may stall.
Once through water, always try the brakes.Wet brakes do not stop your vehicle aseffectively as dry brakes. Drying can beimproved by applying light pressure to thebrake pedal while moving slowly.
Note:Driving through deep water maydamage the transmission. If the front or rearaxle is submerged in water, the axlelubricant and power transfer unit lubricantshould be checked and changed ifnecessary.
Driving on Hilly or Sloping Terrain
Although natural obstacles may make itnecessary to travel diagonally up or downa hill or steep incline, you should alwaystry to drive straight up or straight down.
Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.Whenever driving on a hill, determinebeforehand the route you will use. Do notdrive over the crest of a hill without seeingwhat conditions are on the other side. Donot drive in reverse over a hill without theaid of an observer.
When climbing a steep slope or hill, startin a lower gear rather than downshifting toa lower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If your vehicle stalls, do not try to turnaround because this could cause vehicleroll over. It is better to reverse back to asafe location.
Apply just enough power to the wheels toclimb the hill. Too much power will causethe tires to slip, spin or lose traction,resulting in loss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating.Do not descend in neutral. Disengageoverdrive or move the transmissionselector lever to a lower gear. Whendescending a steep hill, avoid sudden hardbraking as you could lose control. The frontwheels have to be turning in order to steeryour vehicle.

Adding Engine Coolant
WARNINGS
Do not add engine coolant when theengine is hot. Steam and scaldingliquids released from a hot coolingsystem can burn you badly. Also, you canbe burned if you spill coolant on hot engineparts.
Do not put engine coolant in thewindshield washer fluid container. Ifsprayed on the windshield, enginecoolant could make it difficult to seethrough the windshield.
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressurerelief cap. The cooling system is underpressure; steam and hot liquid can comeout forcefully when the cap is loosenedslightly.
Do not add coolant further than theMAX mark.
Note:Do not use stop leak pellets, coolingsystem sealants, or additives as they cancause damage to the engine cooling orheating systems. This damage would notbe covered under your vehicle’s warranty.
Note:During normal vehicle operation, theengine coolant may change color fromorange to pink or light red. As long as theengine coolant is clear and uncontaminated,this color change does not indicate theengine coolant has degraded nor does itrequire the engine coolant to be drained, thesystem to be flushed, or the engine coolantto be replaced.
•Do not mix different colors or types ofcoolant in your vehicle. Make sure thecorrect coolant is used. Mixing ofengine coolants may harm yourengine’s cooling system. The use of animproper coolant may harm engine andcooling system components and mayvoid the warranty. Use predilutedengine coolant meeting the Fordspecification. See Capacities andSpecifications (page 301).
•In case of emergency, a large amountof water without engine coolant maybe added in order to reach a vehicleservice location. In this instance, thecooling system must be drained,chemically cleaned with Motorcraft®Premium Cooling System Flush, andrefilled with engine coolant as soon aspossible. Water alone (without enginecoolant) can cause engine damagefrom corrosion, overheating or freezing.
•Do not use alcohol, methanol, brine orany engine coolants mixed with alcoholor methanol antifreeze (coolant).Alcohol and other liquids can causeengine damage from overheating orfreezing.
•Do not add extra inhibitors or additivesto the coolant. These can be harmfuland compromise the corrosionprotection of the engine coolant.
Unscrew the cap slowly. Any pressure willescape as you unscrew the cap.
Add prediluted engine coolant meeting theFord specification. See Capacities andSpecifications (page 301).
Whenever coolant has been added, thecoolant level in the coolant reservoirshould be checked the next few times youdrive the vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the proper level.

When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate thevehicle in fail-safe mode only as longas necessary to bring the vehicle to rest ina safe location and seek immediate repairs.When in fail-safe mode, the vehicle willhave limited power, will not be able tomaintain high-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
Never remove the coolant reservoircap while the engine is running or hot.
You have limited engine power when in thefail-safe mode, so drive the vehicle withcaution. The vehicle will not be able tomaintain high-speed operation and theengine will run rough. Remember that theengine is capable of completely shuttingdown automatically to prevent enginedamage, therefore:
1.Pull off the road as soon as safelypossible and turn off the engine.
2.Arrange for the vehicle to be taken toan authorized dealer.
3.If this is not possible, wait a shortperiod for the engine to cool.
4.Check the coolant level and replenishif low.
5.Re-start the engine and take yourvehicle to an authorized dealer.
Note:Driving the vehicle without repairingthe engine problem increases the chance ofengine damage. Take your vehicle to anauthorized dealer as soon as possible.
Engine Fluid TemperatureManagement (If Equipped)
WARNING
To reduce the risk of collision andinjury, be prepared that the vehiclespeed may reduce and the vehiclemay not be able to accelerate with fullpower until the fluid temperatures reduce.
Your vehicle has been designed to pull atrailer, but because of the added load, thevehicle’s engine may temporarily reachhigher temperatures during severeoperating conditions such as ascending along or steep grade while pulling a trailerin hot ambient temperatures.
At this time, you may notice your enginecoolant temperature gauge needle movetoward the H and the POWER REDUCEDTO LOWER TEMP message may appearin the information display.
You may notice a reduction in the vehicle’sspeed caused by reduced engine power.Your vehicle has been designed to enterthis mode if certain high temperature/highload conditions take place in order tomanage the engine’s fluid temperatures.The amount of speed reduction willdepend on the vehicle loading, towing,grade, ambient temperature, and otherfactors. If this occurs, there is no need topull off the road. The vehicle can continueto be driven while this message is active
The air conditioning may also cycle on andoff during severe operating conditions toprotect overheating of the engine. Whenthe engine coolant temperature decreasesto a more normal operating temperature,the air conditioning will turn on once again.If you notice any of the following:
