Adjusting Automatic Transmission FluidLevels
Before adding any fluid, make sure thecorrect type is used. The type of fluid usedis normally indicated on the dipstick and alsoin the Technical Specifications section in thischapter.
Note:An overfill condition of transmissionfluid may cause shift or engagementconcerns or possible damage.
Do not use supplemental transmission fluidadditives, treatments or cleaning agents. Theuse of these materials may affecttransmission operation and result in damageto internal transmission components.Reinstall the air filter assembly. After the fluidlevel has been checked and adjusted asnecessary, do the following:
1. Shut the engine off.
2. Loosen the clamp holding the air filterassembly to the rubber hose.
3.Rotate the air filter assembly 90 degreesclockwise without disconnecting thesensor.
4.Seat the air filter assembly back into thegrommets by pushing down on the airfilter assembly.
5. Tighten the clamp.
6. Install and tighten two bolts that attachair filter assembly to the front of thevehicle.
7. Install the bolt cover (if equipped).
8. Reinstall the harness retaining clip intothe front of the air filter assembly.
BRAKE FLUID CHECK
WARNINGS
Do not use any fluid other than therecommended brake fluid as this willreduce brake efficiency. Use of incorrect fluidcould result in the loss of vehicle control,serious personal injury or death.
Only use brake fluid from a sealedcontainer. Contamination with dirt,water, petroleum products or other materialsmay result in brake system damage or failure.Failure to adhere to this warning could resultin the loss of vehicle control, seriouspersonal injury or death.
Do not allow the fluid to touch yourskin or eyes. If this happens, rinse theaffected areas immediately with plenty ofwater and contact your physician.

Loss of air pressure may adversely affect tireperformance. For this reason:
Note:Do not drive the vehicle above 50 mph(80 km/h).
Note:Do not drive further than 120 mi(200 km). Drive only to the closest authorizedLincoln dealer or tire repair shop to haveyour tire inspected.
•Drive carefully and avoid abrupt steeringmaneuvers.
•Periodically monitor tire inflation pressurein the affected tire; if the tire is losingpressure, have the vehicle towed.
•Read the information in the Tips for Useof the Kit section to make sure safeoperation of the kit and your vehicle.
Tips for Use of the Kit
To ensure safe operation of the kit:
•Read all instructions and cautions fully.
•Before operating the kit, make sure yourvehicle is safely off the road and awayfrom moving traffic. Turn on the hazardlights.
•Always set the parking brake to ensurethe vehicle doesn't move unexpectedly.
•Do not remove any foreign objects, suchas nails or screws, from the tire.
•When using the kit, leave the enginerunning (only if the vehicle is outdoors orin a well-ventilated area) so thecompressor does not drain the vehicle'sbattery.
•Do not allow the compressor to operatecontinuously for more than 15 minutes.This will help prevent the compressorfrom overheating.
•Never leave the kit unattended duringoperation.
•Sealant compound contains latex. Thosewith latex sensitivities should useappropriate precautions to avoid anallergic reaction.
•Keep the kit away from children.
•Only use the kit when the ambienttemperature is between -22°F (-30°C) and158°F (70°C).
•Only use the sealing compound beforethe use-by date. The use-by date is on alabel on the sealant canister and can beseen through the rectangular viewingwindow on the bottom of the compressor.Check the use-by date regularly andreplace the canister after four years ofnon-use.
•Do not store the kit unsecured inside thepassenger compartment of the vehicleas it may cause injury during a suddenstop or crash. Always store the kit in itsoriginal location.
•After sealant use, the tire pressuremonitoring system sensor and valve stemon the wheel must be replaced by anauthorized Lincoln dealer.
•Operating the kit could cause anelectrical disturbance in radio, CD, andDVD player operation.
* When inflation only is required fora tire or other objects, the selectormust be in the Air position.

WARNINGS
When inflating the tire for mountingpressures up to 20 psi (1.38 bar)greater than the maximum pressure onthe tire sidewall, the followingprecautions must be taken to protectthe person mounting the tire:
1.Make sure that you have the correcttire and wheel size.
2.Lubricate the tire bead and wheelbead seat area again.
3. Stand at a minimum of 12 ft (3.66 m)away from the wheel and tireassembly.
4. Use both eye and ear protection.
WARNINGS
For a mounting pressure more than20 psi (1.38 bar) greater than themaximum pressure, a Ford dealer orother tire service professional should dothe mounting.
WARNINGS
Always inflate steel carcass tireswith a remote air fill with the personinflating standing at a minimum of 12 ft(3.66 m) away from the wheel and tireassembly.
Important: Remember to replace thewheel valve stems when the road tiresare replaced on your vehicle
It is recommended that the two fronttires or two rear tires generally bereplaced as a pair.
The tire pressure sensors mounted inthe wheels (originally installed on yourvehicle) are not designed to be used inaftermarket wheels.
The use of wheels or tires notrecommended by Ford Motor Companymay affect the operation of your tirepressure monitoring system.
If the tire pressure monitoring systemindicator is flashing, your system ismalfunctioning. Your replacement tiremight be incompatible with your tirepressure monitoring system, or somecomponent of the system may bedamaged.
Safety Practices
WARNINGS
If your vehicle is stuck in snow,mud or sand, do not rapidly spinthe tires; spinning the tires can tear thetire and cause an explosion. A tire canexplode in as little as three to fiveseconds.
Do not spin the wheels at over34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.
Driving habits have a great deal to dowith your tire mileage and safety.
•Observe posted speed limits
•Avoid fast starts, stops and turns

TIRE PRESSURE MONITORING
SYSTEM
WARNING
The tire pressure monitoring system isnot a substitute for manually checkingtire pressures. You should periodically checktire pressures using a pressure gauge.Failure to correctly maintain tire pressurescould increase the risk of tire failure, loss ofcontrol, vehicle rollover and personal injury.
Note: You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
Note: If the tire pressure monitoring systemsensor becomes damaged, it may notfunction.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommended by thevehicle manufacturer on the vehicle placardor tire inflation pressure label. (If your vehiclehas tires of a different size than the sizeindicated on the vehicle placard or tireinflation pressure label, you shoulddetermine the proper tire inflation pressurefor those tires).
As an added safety feature, your vehicle hasbeen equipped with a Tire PressureMonitoring System (TPMS) that illuminates alow tire pressure telltale when one or moreof your tires is significantly under-inflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop andcheck your tires as soon as possible, andinflate them to the proper pressure. Drivingon a significantly under-inflated tire causesthe tire to overheat and can lead to tirefailure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitutefor proper tire maintenance, and it is thedriver’s responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination ofthe TPMS low tire pressure telltale.
Your vehicle has also been equipped with aTPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When thesystem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists.
When the malfunction indicator is illuminated,the system may not be able to detect orsignal low tire pressure as intended. TPMSmalfunctions may occur for a variety ofreasons, including the installation ofreplacement or alternate tires or wheels onthe vehicle that prevent the TPMS from
