Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAirbag readiness
section in theInstrument Clusterchapter. Routine maintenance of the
airbag is not required.
Any difficulty with the system is indicated by one or more of the
following:
•The readiness light (same light as for front airbag system) will either
flash or stay lit.
•The readiness light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and light are repaired.
If any of these things happen, even intermittently, contact your
authorized dealer as soon as possible. Unless serviced, the system may
not function properly in the event of a collision or rollover event.
SOS Post-Crash Alert System™
The system automatically flashes the turn signal lamps and sounds the
horn three times at four second intervals in the event of a serious impact
that deploys an airbag (front, side, side curtain or Safety Canopy)or
the safety belt pretensioners.
The system can be turned off when any one of the following actions are
taken by the driver or any other person:
•pressing the hazard control button,
•or pressing the panic button on the remote entry transmitter.
The feature will continue to operate until the vehicle runs out of power.
Disposal of airbags and airbag equipped vehicles (including
pretensioners)
Contact your authorized dealer as soon as possible. Airbags MUST BE
disposed of by qualified personnel.

•Activate the tow/haul feature to eliminate excessive transmission
shifting and assist in transmission cooling. For additional information,
refer toAutomatic transmission operationin theDrivingchapter.
•Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.
If your vehicle is equipped with AdvanceTracwith RSC, you may
experience AdvanceTracwith RSC activations during typical cornering
maneuvers with a heavily loaded trailer; this is normal. Cornering at a
slower speed while towing will reduce the tendency of the AdvanceTrac
stability enhancement system to activate.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer toSpecial operating conditionsin the
Scheduled Maintenance Guidechapter.
Trailer towing tips
•Practice turning, stopping and backing-up before starting on a trip to
get the feel of the vehicle-trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 km/h) with no full throttle starts.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.

When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the FULL COLD level, or within the
COLD FILL or MIN / MAX range as listed on the engine coolant
reservoir (depending upon application).
•Refer toscheduled maintenance informationfor service interval
schedules.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool,until the appropriate fill level is obtained. If coolant is
filled to the COLD FILL RANGE or FULL COLD level when the engine is
not cool, the system will remain underfilled.
WARNING:Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING:Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.

GENERAL MAINTENANCE INFORMATION
Why maintain your vehicle?
This guide describes the scheduled maintenance required for your
vehicle. Carefully following this schedule helps protect against major
repair expenses resulting from neglect or inadequate maintenance and
may also help to increase the value of your vehicle when you sell or
trade it.
It is your responsibility to see that all scheduled maintenance is
performed and that the materials used meet Ford engineering
specifications. Failure to perform scheduled maintenance specific in this
guide will invalidate warranty coverage on parts affected by the lack of
maintenance. Be sure receipts for completed maintenance are kept with
the vehicle and confirmation of the work performed is always recorded in
this guide.
Your Ford or Lincoln Mercury dealer has factory-trained technicians who
can perform the required maintenance using genuine Ford parts. They
are committed to meeting your service needs and to assuring your
continuing satisfaction.
Protecting your investment
Maintenance is an investment that will pay dividends in the form of
improved reliability, durability and resale value. To ensure the proper
performance of your vehicle and its emission control systems, it is
imperative that scheduled maintenance be completed at the designated
intervals.
Your vehicle is very sophisticated and built with multiple complex
performance systems. Every manufacturer develops these systems using
different specifications and performance features. That’s why it’s
important to rely upon your Ford or Lincoln Mercury dealership to
properly diagnose and repair your vehicle.
Ford Motor Company has recommended maintenance intervals for
various parts and component systems based upon engineering testing.
Ford Motor Company relies upon this testing to determine the most
appropriate mileage for replacement of oils and fluids to protect your
vehicle at the lowest overall cost to you and recommends against
maintenance schedules that deviate from the scheduled maintenance
information.
Ford strongly recommends the use of genuine Ford replacement parts.
Parts other than Ford, Motorcraftor Ford-authorized remanufactured
Scheduled Maintenance Guide

parts that are used for maintenance replacement or for the service of
components affecting emission control must be equivalent to genuine
Ford Motor Company parts in performance and durability. It is the
owner’s responsibility to determine the equivalency of such parts. Please
consult yourWarranty Guidefor complete warranty information.
Non-Ford approved chemicals or additives are not required for factory
recommended maintenance. In fact, Ford Motor Company recommends
against the use of such additive products unless specifically
recommended by Ford for a particular application.
Oil, fluids and flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, discolored fluids that also show signs of
overheating and/or foreign material contamination should be inspected
immediately by a qualified expert such as the factory-trained technicians
at your Ford or Lincoln Mercury Dealership. Your vehicle’s oils and fluids
should be changed at the specified intervals or in conjunction with a
repair. Flushing is a viable way to change fluid for many vehicle
sub-systems during scheduled maintenance. It is critical that systems are
flushed only with new fluid that is the same as that required to fill and
operate the system, or using a Ford-approved flushing chemical.

EXCEPTIONS
In addition, there are several exceptions to the Normal Schedule. They
are listed below:
Normal vehicle axle maintenance
❑Rear axles and power take-off (PTO) units containing synthetic lubricant and light duty trucks equipped with Ford-design
axles are lubricated for life. These lubricants are not to be checked or changed unless a leak is suspected, service is re-
quired or the axle assembly has been submerged in water. The axle and PTO lubricant should be changed anytime the axle
and PTO have been submerged in water. During extended trailer tow operation above 70°F (21°C) ambient and wide open
throttle for extended periods above 45 mph (72 km/h), non-synthetic rear axle lubricants should be replaced every
3,000 miles (4,800 km) or 3 months, whichever occurs first. The 3,000 mile (4,800 km) lubricant change interval may
be waived if the axle was filled with 75W140 synthetic gear lubricant meeting Ford specification WSL-M2C192-A, part
number F1TZ-19580-B or equivalent. Add friction modifier XL-3 (EST-M2C118-A) or equivalent for complete refill of Traction-
Lok rear axles (refer to
Maintenance product and specificationsin theMaintenance and Specificationschapter for details).
The axle lubricant should be changed anytime an axle has been submerged in water.
Police/Taxi/Livery vehicle axle maintenance
❑Replace rear axle lubricant every 100,000 miles (160,000 km). Rear axle lubricant change may be waived if the axle
was filled with 75W140 synthetic gear lubricant meeting Ford specification WSL-M2C192-A, part number FITZ-19580-B or
equivalent. Add four ounces (118 mL) of additive friction modifier XL-3 (EST-M2C118-A) or equivalent for complete refill of
Traction-Lok rear axles. The axle lubricant should be changed anytime the axle has been submerged in water.
E–450 and F–450/550 axle maintenance
❑Replace rear axle lubricant every 100,000 miles (160,000 km) under normal driving conditions on all E–450 and
F–450/550 applications. For E–450 and F–450/550 vehicles operated at or near maximum Gross Vehicle Weights, the
rear axle lubricant should be replaced every 50,000 miles (80,000 km). In addition, this 50,000 mile (80,000 km)
schedule should be observed when the vehicles are operated under the Special Operating Conditions.
California fuel filter replacement
❑If vehicle is registered in California, the California Air Resources Board has determined that the failure to perform this main-
tenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful life.
Ford Motor Company, however, urges you to have all recommended maintenance services performed at the specified inter-
vals and to record all vehicle service.
Class A Motorhome
❑Every two years - Change brake fluid
