TOWING POINTS (IF EQUIPPED)
WARNING: Using recovery hooksis dangerous and should only be done bya person familiar with proper vehiclerecovery safety practices. Improper useof recovery hooks may cause hook failureor separation from the vehicle and couldresult in serious injury or death.
WARNING: Always slowly removethe slack from the recovery strap priorto pulling. Failure to do so can introducesignificantly higher loads which cancause the recovery hooks to break off, orthe recovery strap to fail which can causeserious injury or death.
WARNING: Never link two strapstogether with a clevis pin. These heavymetal objects could become projectilesif the strap breaks and can cause seriousinjury or death.
Your vehicle comes equipped withframe-mounted front recovery hooks.These hooks should never have a loadapplied to them greater than the grossvehicle weight rating of your vehicle.
Before using recovery hooks:
•Make sure all attaching points aresecure and capable of withstandingthe applied load.
•Never use chains, cables or tow strapswith metal hook ends.
•Only use recovery straps that have aminimum breaking strength two tothree times the gross vehicle weight ofthe stuck vehicle.
•Make sure the recovery strap is in goodcondition and free of visible cuts, tearsor damage.
•Use a damper device such as a tarp,heavy blanket or piece of carpetdraped over the recovery strap to helpabsorb the energy in the event thestrap breaks.
•Make sure the stuck vehicle is notloaded heavier than its gross vehicleweight rating specified on thecertification label.
•Always align the tow vehicle and stuckvehicle in a straight line (within 10degrees).
•Keep bystanders to the sides of thevehicle, at a distance of at least twicethe length of the recovery strap. Thishelps avoid injury from the hazard of arecovery hook or strap breaking, or avehicle lurching into their path.

WARNING: If it illuminates whenyou are driving do not continue yourjourney, even if the oil level is correct.Have your vehicle checked.
It illuminates when you switchthe ignition on.
If it illuminates when the engineis running this indicates a malfunction.Stop your vehicle as soon as it is safe todo so and switch the engine off. Check theengine oil level. If the oil level is sufficient,this indicates a system malfunction. Haveyour vehicle checked as soon as possible.
CHANGING THE ENGINE OIL
AND OIL FILTER
WARNING: Do not add engine oilwhen the engine is hot. Failure to followthis instruction could result in personalinjury.
Your vehicle has an Intelligent Oil LifeMonitor™ that calculates the proper oilchange service interval. When theinformation display indicates: OIL CHANGEREQUIRED, change the engine oil and oilfilter. See Information Displays (page71).
The engine oil filter protects your engineby filtering harmful, abrasive or sludgeparticles and particles significantly smallerthan most available will-fit filters. SeeMotorcraft Parts (page 293).

BRAKE FLUID CHECK
WARNING: Do not use any fluidother than the recommended brake fluidas this will reduce brake efficiency. Useof incorrect fluid could result in the lossof vehicle control, serious personal injuryor death.
WARNING: Only use brake fluidfrom a sealed container. Contaminationwith dirt, water, petroleum products orother materials may result in brakesystem damage or failure. Failure toadhere to this warning could result in theloss of vehicle control, serious personalinjury or death.
WARNING: Do not allow the fluidto touch your skin or eyes. If thishappens, rinse the affected areasimmediately with plenty of water andcontact your physician.
WARNING: The brake systemcould be affected if the brake fluid levelis below the MIN mark or above the MAXmark on the brake fluid reservoir.
1.Park your vehicle on a level surface.
2.Look at the brake fluid reservoir to seewhere the brake fluid level is relativeto the MIN and the MAX marks on thereservoir.
Note:If the brake fluid level is between theMIN and the MAX marks on the reservoir, itis acceptable.
Note:If the brake fluid level is below theMIN mark or above the MAX mark, haveyour vehicle checked as soon as possible.
Note:To avoid fluid contamination, thereservoir cap must remain in place and fullytight, unless you are adding fluid.
Only use fluid that meets ourspecifications. See Capacities andSpecifications (page 291).
Brake Fluid Service Interval
Brake fluid absorbs water over time whichdegrades the effectiveness of the brakefluid. Change the brake fluid at thespecified intervals to prevent degradedbraking performance.

Engine-mounted Fuel Filter
Although the fuel system is not fullypressurized when the vehicle is off, someresidual pressure may remain in the fuelsystem since it can take some time for thepressure to completely bleed off.Therefore, we recommend you place anabsorbent cloth below the filter connectorsto absorb any fuel that may drain.
The engine-mounted fuel filter is a plasticdisposable cartridge.
