Why Maintain Your Vehicle?
Carefully following the maintenanceschedule helps protect against major repairexpenses resulting from neglect orinadequate maintenance and may help toincrease the value of your vehicle whenyou sell or trade it. Keep all receipts forcompleted maintenance with your vehicle.
We have established regular maintenanceintervals for your vehicle based uponrigorous testing. It is important that youhave your vehicle serviced at the propertimes. These intervals serve two purposes;one is to maintain the reliability of yourvehicle and the second is to keep your costof owning your vehicle down.
It is your responsibility to have allscheduled maintenance performed and tomake sure that the materials used meetthe specifications identified in this owner'smanual. See Engine Specifications(page 291).
Failure to perform scheduled maintenanceinvalidates warranty coverage on partsaffected by the lack of maintenance.

If you do not use Ford authorized parts theymay not meet our specifications anddepending on the part, it could affectemissions compliance.
Convenience
Many dealerships have extended eveningand Saturday hours to make your servicevisit more convenient and they offer onestop shopping. They can perform anyservices that are required on your vehicle,from general maintenance to collisionrepairs.
Note:Not all dealers have extended hoursor body shops. Please contact your dealerfor details.
Protecting Your Investment
Maintenance is an investment that paysdividends in the form of improvedreliability, durability and resale value. Tomaintain the proper performance of yourvehicle and its emission control systems,make sure you have scheduledmaintenance performed at the designatedintervals.
Your vehicle is equipped with theIntelligent Oil-Life Monitor system, whichdisplays a message in the instrumentcluster display at the proper oil changeinterval. This interval may be up to one yearor 10,000 mi (16,000 km) for gas enginesand up to one year or 15,000 mi(24,000 km) for diesel engines.

Your vehicle can be driven in such a waythat dilutes and increases the level of oilby short trips that do not allow the engineto get to operating temperature, extendedidling, and low speed driving for longperiods of time.
A message appears in the instrumentcluster display when it is time for an oilchange. Make sure you perform the oilchange within two weeks or 500 mi(800 km) of the message appearing. Makesure you reset the Intelligent Oil-LifeMonitor after each oil change. SeeInstrument Cluster (page 64).
If your instrument cluster display resetsprematurely or becomes inoperative, youshould perform the oil change interval atsix months or 5,000 mi (8,000 km) fromyour last oil change. Never exceed one yearor 10,000 mi (16,000 km) between oilchange intervals for gas engines.
Never exceed one year or 15,000 mi(24,000 km) between oil change intervalsfor diesel engines.
Your vehicle is very sophisticated and builtwith multiple, complex, performancesystems. Every manufacturer developsthese systems using differentspecifications and performance features.That is why it is important to rely upon yourdealership to properly diagnose and repairyour vehicle.
Ford Motor Company has recommendedmaintenance intervals for various partsand component systems based uponengineering testing. Ford Motor Companyrelies upon this testing to determine themost appropriate mileage for replacementof oils and fluids to protect your vehicle atthe lowest overall cost to you andrecommends against maintenanceschedules that deviate from the scheduledmaintenance information.
We strongly recommend the use of onlygenuine Ford, Motorcraft orFord-authorized re-manufacturedreplacement parts engineered for yourvehicle.
Additives and Chemicals
This owner's manual and the FordWorkshop Manual list the recommendedadditives and chemicals for your vehicle.We do not recommend using chemicals oradditives not approved by us as part ofyour vehicle’s normal maintenance. Pleaseconsult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is anormal operating characteristic and, byitself, does not necessarily indicate aconcern or that the fluid needs to bechanged. However, a qualified expert, suchas the factory-trained technicians at yourdealership, should inspect discolored fluidsthat also show signs of overheating orforeign material contaminationimmediately.
Make sure to change your vehicle’s oils andfluids at the specified intervals or inconjunction with a repair. Flushing is aviable way to change fluid for many vehiclesub-systems during scheduledmaintenance. It is critical that systems areflushed only with new fluid that is the sameas that required to fill and operate thesystem or using a Ford-approved flushingchemical.

Scheduled Maintenance Services
Maintenance service adjustments mustconform to specifications contained in thismanual, and those shown on the ImportantEngine Information decal. Perform thefollowing services at scheduled intervalsbecause they essential to the life andperformance of your vehicle. Fordrecommends that you performmaintenance on all designated items toachieve best vehicle operation.
There are three types of maintenanceintervals for general vehicle environments:On-Highway, City and Severe Service. Inall applications, monitoring miles(kilometers) and time and when the engineis due for an oil change determine theactual interval. When the engine oil changeis required before the truck lubricationinterval, perform the lubrication at thesame time in order to reduce your vehicle’stime out of service.
Air Brake Adjustment
WARNING: Failure to maintainproper air brake adjustment can resultin reduction or loss of braking ability.
A qualified service technician, keeping tothe instructions in the service manual,should perform air brake inspection andadjustment or repairs.
Cam Brakes - Automatic SlackAdjusters
WARNING: Do not manually adjustthe automatic slack adjusters to correctexcessive push rod stroke as it may resultin reduced brake effectiveness and avehicle crash. Excessive push rod strokeindicates that a problem exists with theautomatic adjuster, with the installationof the adjuster, or with foundation brakecomponents that manual adjustmentdoes not remedy. Seek service from aqualified facility for excessive push rodstroke.
Inspect standard air brakes equipped withautomatic slack adjusters for proper brakeadjustment as listed in the maintenanceschedule charts.
However, inspect the brakes morefrequently when subjecting them to heavyuse or adverse operating conditions suchas:
•Frequent brake applications while fullyloaded.
•Operation on hilly or mountainousterrain.
•Frequent operation on dirt, gravel ormud.
Some aftermarket brake linings alsorequire more frequent inspections.
