Engine Oil Pressure Gauge
Indicates engine oil pressure. At normaloperating temperature, the level indicatoris in the normal range. If the pressure gaugefalls below the normal range, stop yourvehicle, switch off the engine and checkthe engine oil level. Add oil if needed. If theoil level is correct, have your vehiclechecked by an authorized dealer.
Engine Coolant TemperatureGauge
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.
Indicates engine coolant temperature. Atnormal operating temperature, the levelindicator is in the normal range. If theengine coolant temperature exceeds thenormal range, stop your vehicle as soon aspossible, switch off the engine and let theengine cool.
Fuel Gauge
The fuel gauge indicates about how muchfuel is in the fuel tank.
The arrow adjacent to the fuel pumpsymbol indicates on which side of yourvehicle the fuel filler door is located.
Note:The fuel gauge may vary slightlywhen your vehicle is moving or on a slope.
Low Fuel Reminder
A low fuel level reminder displays andsounds when the distance to emptyreaches 50 mi (80 km),25 mi (40 km),10 mi (20 km) and 0 mi (0 km) for allvehicle keys.
Note:The low fuel reminder can appear atdifferent fuel gauge positions depending onfuel economy conditions. This variation isnormal.
Distance to Empty
Indicates the approximate distance yourvehicle can travel on the fuel remaining inthe tank. Changes in driving pattern cancause the value to not only decrease butalso increase or stay constant for periodsof time.
Transmission Fluid TemperatureGauge
Indicates transmission fluid temperature.At normal operating temperature, the levelindicator is in the normal range. If thetransmission fluid temperature exceedsthe normal range, stop your vehicle as soonas possible and verify the airflow is notrestricted by snow or debris blockingairflow through the grille.
Special operating conditions such assnowplowing, towing, or off-road use maycause higher than normal operatingtemperatures. See Special OperatingConditions Scheduled Maintenance(page 252).
To lower the transmission temperatureinto the normal range, alter the severity ofyour driving conditions. Operating thetransmission for extended periods with thegauge in the higher than normal area maycause internal transmission damage. If thegauge continues to show hightemperatures, see an authorized dealer.

When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 247).
Note:Make sure that the coolant level isbetween the MIN and MAX marks on thecoolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -29°F (-34°C) and -35°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNING: Do not add enginecoolant when the engine is on or thecooling system is hot. Failure to followthis instruction could result in personalinjury.
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.
Note: Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 224). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and maynot be covered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 224).Using water that has not been deionizedmay contribute to deposit formation,corrosion and plugging of the small coolingsystem passageways.
Note: Coolants marketed for all makes andmodels may not be approved to Fordspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do thefollowing:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add prediluted coolant approved tothe correct specification. SeeCapacities and Specifications (page224).
3.Add enough prediluted coolant toreach the correct level.

4.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
5.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the correct level.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have yourvehicle checked as soon as possible.Operating an engine with a low level ofcoolant can result in engine overheatingand possible engine damage.
Note:During normal vehicle operation, thecoolant may change color, and slightlydarken. As long as the coolant is clear anduncontaminated, this color change does notindicate the coolant has degraded nor doesit require the coolant to be drained, thesystem to be flushed, or the coolant to bereplaced.
In case of emergency, you can add a largeamount of water without coolant in orderto reach a vehicle service location. In thisinstance, qualified personnel:
1.Must drain the cooling system.
2.Chemically clean the coolant system.
3.Refill with coolant that meets thecorrect specification. See Capacitiesand Specifications (page 224).
Water alone, without coolant, can causeengine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling processis not yet available.
Dispose of used engine coolant in anappropriate 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 increase thecoolant concentration above 50%.
•A coolant concentration of 60%provides improved freeze pointprotection. Coolant concentrationsabove 60% decrease the overheatprotection characteristics of thecoolant and may cause enginedamage.
If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of thecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.

Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Addprediluted coolant approved to the correctspecification. See Capacities andSpecifications (page 224).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, thecoolant temperature gauge moves towardthe red zone:
A warning lamp illuminates anda message may appear in theinformation display.
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. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is 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.
Your vehicle has limited engine powerwhen in the fail-safe mode, drive yourvehicle with caution. Your vehicle does notmaintain high-speed operation and theengine may operate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1.Pull off the road as soon as safelypossible and switch the engine off.
2.If you are a member of a roadsideassistance program, we recommendthat you contact your roadsideassistance service provider.
3.If this is not possible, wait a shortperiod for the engine to cool.
