If the light is blinking, engine misfire isoccurring which could damage yourcatalytic converter. Drive in a moderatefashion (avoid heavy acceleration anddeceleration) and have your vehicleserviced immediately.
WARNING
Under engine misfire conditions,excessive exhaust temperaturescould damage the catalyticconverter, the fuel system, interior floorcoverings or other vehicle components,possibly causing a fire. Have your vehicleserviced immediately.
The service engine soon indicator lightilluminates when the ignition is first turnedon prior to engine start to check the bulband to indicate whether the vehicle is readyfor Inspection/Maintenance (I/M) testing.
Normally, the service engine soon light willstay on until the engine is cranked, thenturn itself off if no malfunctions arepresent. However, if after 15 seconds theservice engine soon light blinks eight times,it means that the vehicle is not ready forI/M testing. See Emission ControlSystem (page 29).

Trailer Brakes
WARNING
Do not connect a trailer's hydraulicbrake system directly to yourvehicle's brake system. Your vehiclemay not have enough braking power andyour chances of having a collision greatlyincrease.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if youinstall them properly and adjust them tothe manufacturer's specifications. Thetrailer brakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.
Separate functioning brake systemsare required for safe control of towedvehicles and trailers weighing morethan 1500 pounds (680 kilograms)when loaded.
Trailer Lamps
WARNING
Never connect any trailer lamp wiringto the vehicle's tail lamp wiring; thismay damage the electrical systemresulting in fire. Contact your authorizeddealer as soon as possible for assistancein proper trailer tow wiring installation.Additional electrical equipment may berequired.
Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, direction indicators and hazard lightsare working.
Before Towing a Trailer
Practice turning, stopping and backing upto get the feel of your vehicle-trailercombination before starting on a trip.When turning, make wider turns so thetrailer wheels clear curbs and otherobstacles.
When Towing a Trailer
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thegearshift in park (P) to aid engine andtransmission cooling and to help airconditioning performance.
•Switch off the speed control withheavy loads or in hilly terrain. Thespeed control may turn offautomatically when you are towing onlong, steep grades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy andtransmission cooling.
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1.Turn the steering wheel to point yourvehicle tires away from traffic flow.

BREAKING-IN
You need to break in new tires forapproximately 300 miles (480kilometers). During this time, your vehiclemay exhibit some unusual drivingcharacteristics.
Avoid driving too fast during the first 1000miles (1600 kilometers). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Do not tow during the first 1000 miles(1600 kilometers).
REDUCED ENGINE
PERFORMANCE
WARNING
Continued operation will increase theengine temperature and cause theengine to shut down completely.
If the engine coolant temperature gaugeneedle moves to the upper limit position,the engine is overheating. See Gauges(page 13).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends onambient temperature, vehicle load andterrain. The engine will continue to operatewith limited power for a short time.
If the engine temperature continues to rise,the fuel supply to the engine will reduce.The air conditioning will switch off and theengine cooling fan will operate continually.
1.Reduce your speed gradually and stopyour vehicle as soon as it is safe to doso.
2.Switch the engine off immediately toprevent severe engine damage.
3.Wait for the engine to cool down.
4.Check the coolant level. See EngineCoolant Check (page 84).
5.Have your vehicle checked by anauthorized dealer as soon as possible.
ECONOMICAL DRIVING
Your fuel economy is affected by severalthings, such as how you drive, theconditions you drive under, and how youmaintain your vehicle.
You may improve your fuel economy bykeeping these things in mind:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds withoutstopping.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving.
•Close the windows for high-speeddriving.
•Drive at reasonable speeds (travelingat 55 mph [88 km/h] uses 15% lessfuel than traveling at 65 mph [105km/h]).
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
Avoid these actions; they reduce your fueleconomy:
•Sudden accelerations or hardaccelerations.
•Revving the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on coldmornings.

ENGINE COOLANT CHECK
WARNINGS
Do not add engine coolant when theengine is hot. Steam and scaldingliquids released from a hot coolingsystem can burn you badly. Also, spillingcoolant on hot engine parts can burn you.
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 you loosen the capslightly.
Do not add coolant further than theMAX mark.
When the engine is cold, check theconcentration and level of the enginecoolant at the intervals listed in thescheduled maintenance information. SeeScheduled Maintenance (page 128).
Note:Make sure that the level is betweenthe MIN and MAX marks on the coolantreservoir.
Note:Coolant expands when it is hot. Thelevel may extend beyond the MAX mark
Note:If the level is at the MIN mark, belowthe MIN mark, or empty, add coolantimmediately. See Adding Engine Coolantin this chapter.
The coolant concentration should bemaintained within 48% to 50%, whichequates to a freeze point between -30°F(-34°C) and -34°F (-37°C).
Note:For best results, coolantconcentration should be tested with arefractometer such as Robinair® Coolantand Battery Refractometer 75240. We donot recommend the use of hydrometers orcoolant test strips for measuring coolantconcentrations.
Note:Automotive fluids are notinterchangeable. Do not use engine coolant,antifreeze or windshield washer fluid outsideof its specified function and vehicle location.
Adding Engine Coolant
Note:Do not use stop leak pellets, coolingsystem sealants, or additives as they cancause damage to the engine cooling orheating systems. Your vehicle’s warrantydoes not cover this damage.
84Motorhome (TY3) , enUSA, First PrintingMaintenance

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 the engine’scooling system. The use of an impropercoolant may harm the engine andcooling system components and mayvoid the warranty. Use predilutedengine coolant meeting the Fordspecification. See Capacities andSpecifications (page 118).
•In case of emergency, you can add alarge amount of water without enginecoolant in order to reach a vehicleservice location. In this instance, youmust have the cooling system drained,chemically cleaned with MotorcraftPremium 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 118).
Whenever you add coolant, check thecoolant level in the coolant reservoir thenext few times you drive the vehicle. Ifnecessary, add enough prediluted enginecoolant to bring the coolant level to theproper level.
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 freeze andcorrosion protection characteristics ofthe engine coolant and may causeengine damage.
85Motorhome (TY3) , enUSA, First PrintingMaintenance

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 you deplete the engine coolant supply,this feature allows you to drive your vehicletemporarily before you incur incrementalcomponent damage. The fail-safe distancedepends on ambient temperatures, vehicleload 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 indicator will light.
The service engine soonindicator will light.
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.
•This will disable the air conditioningsystem.
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.
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 switch off the engine.
2.Have your vehicle towed to anauthorized 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.
