POWER STEERING FLUID
CHECK
Check the power steering fluid. SeeScheduled Maintenance (page 573). Ifadding fluid is necessary, use onlyMERCON LV ATF
Note:This procedure is for vehicles withgasoline engines. Vehicles with dieselengines are similar. See Under HoodOverview in your diesel supplement.
Check the fluid level when it is at ambienttemperature.
1. Check the fluid level in the reservoir. Itshould be between the MIN and MAXrange. Do not add fluid if the level iswithin this range.
2.If the fluid level is low, add fluid to bringthe fluid level up to between the MINand MAX range.
3. Switch the engine on.
4.While the engine idles, turn the steeringwheel left and right several times.
5. Switch the engine off.
6. Recheck the fluid level in the reservoir.Do not add fluid if the level is betweenthe MIN and MAX range.
7. If the fluid is low, add fluid in smallamounts, continuously checking thelevel until it is between the MIN andMAX range. For proper fluid type, SeeCapacities and Specifications (page415). Be sure to put the cap back on thereservoir.
WASHER FLUID CHECK

WARNINGS
This vehicle may be fitted with morethan one battery. Removing thebattery cables from only one batterydoes not disconnect your vehicle electricalsystem. Make sure you disconnect thebattery cables from all batteries whendisconnecting power. Failure to do so maycause serious personal injury or propertydamage.
Your vehicle is fitted with a Motorcraftmaintenance-free battery which normallydoes not require additional water.
When a battery replacement is required,you must use a recommendedreplacement battery that matches theelectrical requirements of the vehicle.
Note:After cleaning or replacing thebattery, make sure you reinstall the batterycover or shield.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect the low voltage battery performanceand durability. This may also affect theperformance of other electrical systems inthe vehicle.
For longer, trouble-free operation, keep thetop of the battery clean and dry.
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 441). Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 95).Reset the radio station presets. SeeAudio System (page 441).
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.
