2017 FORD TAURUS Owners Manual

How Fail-Safe Cooling Works
If the engine begins to overheat,the coolant temperature gaugemoves toward the 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
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate yourvehicle in fail-safe mode only as longas necessary to bring your vehicle to restin a safe location and seek immediaterepairs. When in fail-safe mode, yourvehicle will have limited power, will not beable to maintain high-speed operation, andmay completely shut down withoutwarning, potentially losing engine power,power steering assist, and power brakeassist, which may increase the possibilityof a crash resulting in serious injury.
WARNINGS
Never remove the coolant reservoircap when the engine is running orhot.
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.
4. Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5. When the engine temperature cools,you can re-start the engine. Have yourvehicle checked as soon as possible tominimize engine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.
Engine Coolant TemperatureManagement (If Equipped)
WARNING
To reduce the risk of crash and injury,be prepared that the vehicle speedmay reduce and the vehicle may notbe able to accelerate with full power untilthe coolant temperature reduces.

Maintenance

If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a longor steep grade in high ambienttemperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehiclespeed caused by reduced engine power inorder to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and ambienttemperature. If this occurs, there is no needto pull off the road. You can continue todrive your vehicle.
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature decreases to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1. Pull off the road as soon as safelypossible and shift the transmission intopark (P).
2. Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. Afterseveral minutes, if the temperaturedoes not drop, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4. If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5. If the coolant level is normal, restartthe engine and continue.

BRAKE FLUID CHECK
WARNINGS
Do not use any fluid other than therecommended brake fluid as this willreduce brake efficiency. Use ofincorrect fluid could result in the loss ofvehicle control, serious personal injury ordeath.
Only use brake fluid from a sealedcontainer. Contamination with dirt,water, petroleum products or othermaterials may result in brake systemdamage or failure. Failure to adhere to thiswarning could result in the loss of vehiclecontrol, serious personal injury or death.
Do not allow the fluid to touch yourskin or eyes. If this happens, rinse theaffected areas immediately withplenty of water and contact your physician.
A fluid level between the MAX andMIN lines is within the normaloperating range and there is no needto add fluid. A fluid level not in the normaloperating range could compromise theperformance of the system. Have yourvehicle checked immediately.
To avoid fluid contamination, the reservoircap must remain in place and fully tight,unless you are adding fluid.
Only use fluid that meets Fordspecifications. See Capacities andSpecifications (page 297).
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an electricpower steering (EPS) system. There is nofluid reservoir to check or fill.
WASHER FLUID CHECK
WARNING
If you operate your vehicle intemperatures below 40

Add fluid to fill the reservoir if the level islow. Only use a washer fluid that meetsFord specifications. See Capacities andSpecifications (page 297).
State or local regulations on volatileorganic compounds may restrict the useof methanol, a common windshield washerantifreeze additive. Washer fluidscontaining non-methanol antifreezeagents should be used only if they providecold weather protection without damagingthe vehicle’s paint finish, wiper blades orwasher system.
FUEL FILTER
Your vehicle is equipped with a lifetimefuel filter that is integrated with the fueltank. Regular maintenance or replacementis not needed.
CHANGING THE 12V BATTERY

Maintenance

If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
Because your vehicle’s engine iselectronically controlled by a computer,some control conditions are maintainedby power from the battery. When thebattery is disconnected or a new batteryis installed, the engine must relearn its idleand fuel trim strategy for optimumdriveability and performance. Flexible fuelvehicles (FFV) must also relearn theethanol content of the fuel for optimumdriveability and performance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While theengine is warming up, complete thefollowing: Reset the clock. See AudioSystem (page 315). Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 78).Reset the radio station presets. SeeAudio System (page 315).
6.Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km)to completely relearn the idle trim andfuel trim strategy.
Note:If you do not allow the engine torelearn the idle and fuel trim strategy, theidle quality of your vehicle may be adverselyaffected until the engine computereventually relearns the idle trim and fueltrim strategy.
Note:For flexible fuel vehicles, if you areoperating on E85, you may experience poorstarts or an inability to start the engine anddriveability problems until the fuel trim andethanol content have been relearned.
Make sure that you dispose of old batteriesin an environmentally friendly way. Seekadvice from your local authority aboutrecycling old batteries.
If storing your vehicle for more than 30days without recharging the battery, werecommend that you disconnect thebattery cables to maintain battery chargefor quick starting.
