INSTRUMENT CLUSTER
WARNING LAMPS
Depending on your vehicle options, somewarning lamps can appear different or notat all.
Anti-Lock Brake System
If it illuminates when you aredriving, this indicates amalfunction. Your vehiclecontinues to have normal braking withoutthe anti-lock brake system function. Haveyour vehicle checked as soon as possible.
Battery
It illuminates when you switchthe ignition on.
If it illuminates when the engineis running, this indicates your vehiclerequires service. Have your vehiclechecked as soon as possible.
Brake System
It illuminates when you apply theparking brake and the ignition ison. If it illuminates when yourvehicle is moving, make sure theparking brake is released. If theparking brake is released, thisindicates low brake fluid level or the brakesystem requires service. Have your vehiclechecked as soon as possible.
Note:Indicators may vary depending onregion.

HOW DOES THE ENGINE BLOCKHEATER WORK
The engine block heater warms the enginecoolant. This allows the climate controlsystem to quickly respond. The equipmentincludes a heater element installed in theengine block and a wire harness. You canconnect the system to a grounded 110 voltAC electrical source.
Note:The engine block heater is mosteffective when outdoor temperatures arebelow 0°F (-18°C). We recommend the useof engine block heater to improve enginecold start performance.
USING THE ENGINE BLOCKHEATER
Make sure the receptacle terminals areclean and dry prior to use. Clean them witha dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hoursof energy per hour of use. The system doesnot have a thermostat. It achievesmaximum temperature afterapproximately three hours of operation.Using the engine block heater longer thanthree hours does not improve systemperformance and unnecessarily useselectricity.
STOPPING THE ENGINE
STOPPING THE ENGINE WHENYOUR VEHICLE IS STATIONARY -VEHICLES WITHOUT: PUSHBUTTON START
1.Shift into park (P).
2.Apply the parking brake.
3.Wait until the engine reaches idlespeed.
4.Turn the key to position 0.
STOPPING THE ENGINE WHENYOUR VEHICLE IS STATIONARY -VEHICLES WITH: PUSH BUTTONSTART
1.Shift into park (P).
2.Apply the parking brake.
3.Wait until the engine reaches idlespeed.
4.Press the push button ignition switch.
STOPPING THE ENGINE WHENYOUR VEHICLE IS MOVING -VEHICLES WITHOUT: PUSHBUTTON START
WARNING: Switching off theengine when your vehicle is still movingresults in a significant decrease inbraking assistance. Higher effort isrequired to apply the brakes and to stopyour vehicle. A significant decrease insteering assistance could also occur. Thesteering does not lock, but higher effort

Using low-sulfur diesel fuel(16-500 ppm) or high-sulfurdiesel fuel (greater than 500ppm) in your diesel engine will causecertain emission components tomalfunction which could also cause theservice engine soon light to illuminateindicating an emissions-related concern.
Diesel fuel is adjusted seasonally for coldtemperature. For best results attemperatures below 19°F (-7°C), werecommend using a diesel fuel which hasbeen seasonally adjusted for the ambientconditions.
Choosing the Right Fuel: VehiclesOperated Where Ultra Low SulfurDiesel Fuel Is Not Required
For the engine to operate reliably onlow-sulfur or high-sulfur diesel fuel, theengine must be a factory-built high-sulfurengine (available as a dealer order optionfor select markets) or an ultra-low sulfurdiesel fuel configured engine that has beenretrofitted for high-sulfur diesel fuel usingauthorized dealer service parts. Failure touse retrofit components other than thoseavailable through your authorized dealerresults in coolant system damage, engineoverheating, selective catalyst reductionsystem or diesel particulate filter damageand possible base engine damage.
Use only a diesel engine configured for usewith high-sulfur diesel fuel in markets withdiesel fuel that has sulfur content greaterthan 15 ppm. Using low-sulfur diesel fuel(16–500 ppm) or high-sulfur diesel fuel(greater than 500 ppm) in a diesel enginedesigned to use only ultra-low sulfur dieselfuel could result in damage to engineemission control devices and the aftertreatment system, potentially renderingthe vehicle inoperable.
Vehicles with engines configured for usewith high-sulfur diesel fuel are onlyavailable for sale in countries whereultra-low sulfur diesel fuel is generally notavailable or mandated by the government.Vehicles originally sold in an ultra-lowsulfur diesel fuel market that aresubsequently exported to non-ultra lowsulfur diesel fuel markets will need to beretrofitted at the customer’s expense usingFord authorized dealer service parts inorder to be reliably operated on non-ultralow sulfur diesel fuel.
Biodiesel
WARNING: Do not mix diesel withgasoline, gasohol or alcohol. This couldcause an explosion.
Note:Do not use home heating oil,agricultural fuel, raw fats and oils, wastecooking greases, biodiesel greater than 20%or any diesel not intended for highway use.Damage to the fuel injection system, engineand exhaust catalyst, and diesel particulatefilter can occur if you use an improper fuel.Red dye is used to identify fuels intendedfor agricultural and non-highway use.
You can operate your vehicle on dieselfuels containing up to 20% biodiesel, alsoknown as B20.
Biodiesel fuel is a chemically convertedproduct from renewable fuel sources, suchas vegetable oils, animal fats and wastecooking greases.
To help achieve acceptable engineperformance and durability when usingbiodiesel in your vehicle:
•Confirm the biodiesel content of thefuel to be B20 (20% biodiesel) or less.
•Only use biodiesel fuel of good qualitythat complies with industry standards.

We recommend the use of a wheel lift anddollies or flatbed equipment to tow yourvehicle. Vehicle damage could occur iftowed incorrectly, or by any other means.
Front-wheel and rear-wheel drive vehiclesmust have their designated drive wheelsoff the ground regardless of towingdirection. Use tow dollies to preventdamage to the transmission.
All-wheel or four-wheel drive vehiclesrequire that all wheels be off the groundusing a wheel lift and dollies or flatbedequipment. This prevents damage to thetransmission and drive system.
Note:You need to switch on the ignition tounlock the steering.
Note:Make sure you check the steeringcolumn before towing. It could lock if thebattery is dead.
FAIL-SAFE COOLING
WHAT IS FAIL-SAFE COOLING
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs due tooverheating.
The fail-safe distance depends on outsidetemperature, vehicle load and terrain.
HOW DOES FAIL-SAFE COOLINGWORK
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine.
Note:Have your vehicle checked as soonas possible to minimize engine damage.
DRIVING WHEN FAIL-SAFE MODEIS ACTIVATED
WARNING: Fail-safe mode is foruse during emergencies only. Operateyour vehicle in fail-safe mode only aslong as necessary to bring your vehicleto rest in a safe location and seekimmediate repairs. When in fail-safemode, your vehicle will have limitedpower, will not be able to maintainhigh-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.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
