Engine Oil Pressure Gauge
Indicates engine oil pressure. The needleshould stay in the normal operating range(between L and H). If the needle fallsbelow the normal range, stop the vehicle,turn off the engine and check the engineoil level. Add oil if needed. If the oil level iscorrect, have your vehicle checked by yourauthorized dealer.
Engine Coolant TemperatureGauge
WARNING
Never remove the coolant reservoircap while the engine is running or hot.
Indicates engine coolant temperature. Atnormal operating temperature, the levelindicator will be in the normal range. If theengine coolant temperature exceeds thenormal range, stop the vehicle as soon assafely possible, switch off the engine andlet the engine cool.
Transmission Fluid TemperatureGauge
Indicates transmission fluid temperature.At normal operating temperature, the levelindicator will be in the normal range. If thetransmission fluid temperature exceedsthe normal range, stop the vehicle as soonas safely possible and verify the airflow isnot restricted such as snow or debrisblocking airflow through the grill. Also,higher than normal operating temperaturecan be caused by special operationconditions (i.e. snowplowing, towing oroff-road use). Refer to Special operatingconditions in the scheduled maintenanceinformation for instructions. Operating the
transmission for extended periods of timewith the gauge in the higher than normalarea may cause internal transmissiondamage. Altering the severity of the drivingconditions is recommended to lower thetransmission temperature into the normalrange. If the gauge continues to show hightemperatures, see your authorized dealer.
Fuel Gauge
Note:The fuel gauge may vary slightlywhen your vehicle is moving or on a gradient.
Switch the ignition on. The fuel gauge willindicate approximately how much fuel isleft in the fuel tank. The arrow adjacent tothe fuel pump symbol indicates on whichside of your vehicle the fuel filler door islocated.
The needle should move toward F whenyou refuel your vehicle. If the needle pointsto E after adding fuel, this indicates yourvehicle needs service soon.
After refueling some variability in needleposition is normal:
•It may take a short time for the needleto reach F after leaving the gas station.This is normal and depends upon theslope of pavement at the gas station.
•The fuel amount dispensed into thetank is a little less or more than thegauge indicated. This is normal anddepends upon the slope of pavementat the gas station.
•If the gas station nozzle shuts offbefore the tank is full, try a differentgas pump nozzle.
Low Fuel Reminder
A low fuel reminder triggers when the fuelgauge needle is at 1/16th.

Diesel MessagesWARNING
When the CLEANING EXHAUSTFILTER message appears in theinformation display, do not park nearflammable materials, vapors or structuresuntil filter cleaning is complete.
ActionMessage
The coolant additive needs checking. Refer to your dieselsupplement for more information.CHECK COOLANTADDITIVE
Your vehicle has entered the cleaning mode. Various engineactions will raise the exhaust temperature in the DieselParticulate Filter system to burn off the particles (exhaustsoot). After the vehicle burns the particles off the exhausttemperature will return to normal levels. This message isNORMAL. Refer to your diesel supplement for more informa-tion.
CLEANING EXHAUSTFILTER
The diesel particulate filter is full of particles (exhaust soot)and you are not operating the vehicle in a manner that allowsnormal cleaning. One of these messages will stay on until theexhaust filter cleaning has begun, at which time the CLEANINGEXHAUST FILTER message displays. We recommend youdrive the vehicle above 30 mph (48 km/h) until the CLEANINGEXHAUST FILTER message turns off. Refer to your dieselsupplement for more information.
EXHAUST OVER-LOADED DRIVE TOCLEANEXHAUST AT LIMITDRIVE TO CLEAN NOW
The diesel particulate filter will continue to fill with particles(exhaust soot) if you ignore this message. The service enginesoon light will illuminate and engine power may be limited, ifcleaning is not permitted. Dealer service will then be requiredto restore your vehicle to full-power operation.
Your vehicle exhaust system temperature exceeds intendedoperating range. If this warning occurs, a chime will sound,followed by reduced engine power. The engine will shut downwhen your vehicle speed is below 3 mph (5 km/h). Stop thevehicle as soon as safely possible. Have the system checkedby an authorized dealer.

Do not crank the engine for more than 10seconds at a time as starter damage mayoccur. If the engine fails to start, turn thekey to off and wait 30 seconds beforetrying again.
Do not use starting fluid such as ether inthe air intake system. Such fluid couldcause immediate explosive damage to theengine and possible personal injury.
If you should experience cold weatherstarting problems on E85 ethanol, andneither an alternative brand of E85 ethanolnor an engine block heater is available, theaddition of unleaded gasoline to your tankimproves cold starting performance. Yourvehicle is designed to operate on E85ethanol alone, unleaded gasoline alone, orany mixture of the two.
If the Engine Fails to Start Using thePreceding Instructions (Flexible FuelVehicles Only)
1.Press and hold down the acceleratorone-third to one-half the way to thefloor, then crank the engine.
2.When the engine starts, release thekey, then gradually release theaccelerator pedal as the engine speedsup. If the engine still fails to start,repeat Step 1.
Guarding Against Exhaust Fumes
WARNING
If you smell exhaust fumes insideyour vehicle, have your vehiclechecked by your authorized dealerimmediately. Do not drive your vehicle ifyou smell exhaust fumes. Carbonmonoxide is present in exhaust fumes.Take precautions to avoid its dangerouseffects.
Important Ventilating Information
If you stop your vehicle and the leave theengine idling for long periods of time, werecommend that you do one of thefollowing:
•Open the windows at least 1 inch (2.5centimeters)
•Set your climate control to outside air.
ENGINE BLOCK HEATER (IF
EQUIPPED)
WARNINGS
Failure to follow engine block heaterinstructions could result in propertydamage or serious personal injury.
Do not use your heater withungrounded electrical systems ortwo-pronged adapters. There is a riskof electrical shock.
Note:The heater is most effective whenoutdoor temperatures are below 0°F(-18°C).
The heater acts as a starting aid bywarming the engine coolant. This allowsthe climate control system to respondquickly. The equipment includes a heaterelement (installed in the engine block) anda wire harness. You can connect thesystem to a grounded 120-volt ACelectrical source.
We recommend that you do the followingfor a safe and correct operation:
•Use a 16-gauge outdoor extension cordthat is product certified byUnderwriter’s Laboratory (UL) orCanadian Standards Association(CSA). This extension cord must besuitable for use outdoors, in cold

Recycled Engine Coolant
Ford Motor Company does not recommendthe use of recycled engine coolant since aFord-approved recycling process is not yetavailable.
Used engine coolant should be disposedof in an appropriate manner. Follow yourcommunity’s regulations and standardsfor recycling and disposing of automotivefluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to have a Fordauthorized dealer increase the coolantconcentration above 50%.
•A coolant concentration of 60% willprovide improved freeze pointprotection. Engine coolantconcentrations above 60% willdecrease the overheat protectioncharacteristics of the engine coolantand may cause engine damage.
If you drive in extremely hot climates:
•It may be necessary to have a Fordauthorized dealer decrease the coolantconcentration to 40%.
•A coolant concentration of 40% willprovide improved overheat protection.Engine coolant concentrations below40% will decrease the corrosion/freezeprotection characteristics of the enginecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted enginecoolant for optimum cooling system andengine protection.
What You Should Know About Fail-Safe Cooling
If the engine coolant supply is depleted,this feature allows the vehicle to be driventemporarily before incremental componentdamage is incurred. The “fail-safe”distance depends on ambienttemperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the enginecoolant temperature gauge will move tothe red (hot) area and:
The coolant temperaturewarning light will illuminate.
The service engine soonindicator will illuminate.
If the engine reaches a presetover-temperature condition, the enginewill automatically switch to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs the vehicle will stilloperate. However:
•The engine power will be limited.
•The air conditioning system will bedisabled.
Continued operation will increase theengine temperature and the engine willcompletely shut down, causing steeringand braking effort to increase.
Once the engine temperature cools, theengine can be re-started. Take your vehicleto an authorized dealer as soon as possibleto minimize engine damage.
