4. Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.
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 your vehiclechecked as soon as possible. Operating anengine with a low level of coolant can resultin engine overheating and possible enginedamage.
Note:If your vehicle has orange coolant,during normal vehicle operation, the coolantmay change color from orange to pink orlight red. 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 engine coolant inorder to reach a vehicle service location. Inthis instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with engine coolant as soon aspossible.
Water alone, without engine coolant, cancause engine 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 of thecoolant.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling process isnot yet available.
Dispose of used engine coolant in anappropriate manner. Follow yourcommunity's regulations and standards forrecycling and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60% providesimproved freeze point protection. Coolant concentrations above 60%decrease the overheat protectioncharacteristics of the coolant and maycause engine damage.

Maintenance

WARNING: This vehicle may havemore than one battery. Removing thebattery cables from only one battery doesnot 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, youmust use a recommended replacementbattery that matches the electricalrequirements of the vehicle.
Note:After cleaning or replacing the battery,make sure you reinstall the battery cover orshield.
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, somecontrol conditions are maintained by powerfrom the battery. When the battery isdisconnected or a new battery is installed,the engine must relearn its idle and fuel trimstrategy for optimum driveability andperformance. Flexible fuel vehicles (FFV)must also relearn the ethanol content of thefuel for optimum driveability andperformance.
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 the engineis warming up, complete the following:Reset the clock. Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 104). Resetthe radio station presets. See AudioSystem (page 434).
6. Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km) tocompletely relearn the idle trim and fueltrim 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 fuel trimstrategy.

Vertical Aim Adjustment
1.Park your vehicle directly in front of a wallor screen on a level surface,approximately 25 ft (7.6 m) away.
2. Measure the height from the center ofyour headlamp (indicated by a dimple atthe center of the outboard projector lens)to the ground and mark an 8 ft (2.4 m)horizontal reference line on the verticalwall or screen at this height (a piece ofmasking tape works well).
Note:To see a clearer light pattern foradjusting, you may want to block the lightfrom one headlamp while adjusting theother.
3. Switch on the low beam headlamps toilluminate the wall or screen and openthe hood. Cover one of the headlampsso no light hits the wall.
4.For halogen or LED headlamps: On thewall or screen you will observe a lightpattern with a distinct horizontal edgetoward the right. If this edge is not at thehorizontal reference line, you will needto adjust the beam so the edge is at thesame height as the horizontal referenceline.
5. Locate the vertical adjuster on eachheadlamp. Use a #2 Phillips screwdriverto turn the adjuster eithercounterclockwise or clockwise in orderto adjust the vertical aim of theheadlamp.
