Additional equipment such assnowplow equipment may affect theperformance of the airbag sensorsincreasing the risk of injury. Please refer tothe Body Builders Layout Book forinstructions about the appropriateinstallation of additional equipment.
All occupants of the vehicle,including the driver, should alwaysproperly wear their safety belts, evenwhen provided with an airbagsupplemental restraint system (SRS).
Your vehicle is equipped with a driver andpassenger airbag supplemental restraintsystem. The supplemental restraint systemwill activate in certain frontal and offsetfrontal collisions when the vehicle sustainssufficient frontal deceleration.
Careless or high speed driving whileplowing snow that results in sufficientvehicle decelerations can deploy theairbag. Such driving also increases the riskof accidents
Never remove or defeat the trippingmechanisms designed into the snowremoval equipment by its manufacturer.Doing so may cause damage to the vehicleand the snow removal equipment as wellas possible airbag deployment.
Engine temperature while plowing
When driving with a plow, your engine mayrun at a higher temperature than normalbecause the attached snowplow blade willrestrict airflow to the radiator.
•If you are driving more than 14.91 mi(24 km) at temperatures abovefreezing, angle the plow blade eitherfull left or full right to providemaximum airflow to the radiator.
•If you are driving less than 14.91 mi(24 km) at speeds up to 44.7 mph(72 km/h) in cold weather, you will notneed to worry about blade position toprovide maximum airflow.
Transmission operation whileplowing
WARNING
Do not spin the wheels at over34.2 mph (55 km/h). The tires mayfail and injure a passenger orbystander.
•Shift transfer case to 4L (4WD Low)when plowing in small areas at speedsbelow 5 mph (8 km/h).
•Shift transfer case to 4H (4WD High)when plowing larger areas or light snowat higher speeds. Do not exceed 15 mph(24 km/h).
•Do not shift the transmission from aforward gear to R (Reverse) until theengine is at idle and the wheels havestopped.

For scheduled intervals of the fluid checksand changes, See ScheduledMaintenance (page 440). Yourtransmission does not consume fluid.However, the fluid level should be checkedif the transmission is not working properly,i.e., if the transmission slips or shifts slowlyor if you notice some sign of fluid leakage.
Automatic transmission fluid expandswhen warmed. To obtain an accurate fluidcheck, drive the vehicle until it is at normaloperating temperature (approximately19 mi (30 km)). Verify that thetransmission fluid temperature gauge,located on the instrument cluster, is withinnormal range.
1.Drive the vehicle 19 mi (30 km)until itreaches normal operating temperature.
2.Park the vehicle on a level surface andengage the parking brake.
3.With the engine running, parking brakeengaged and your foot on the brakepedal, move the gearshift lever throughall of the gear ranges. Allow sufficienttime for each gear to engage.

Contamination with dirt, water,petroleum products or other materials may result in brake system damage and possiblefailure.3Add the coolant type originally equipped in your vehicle.4Ford has designed your engine to use Motorcraft engine oils or equivalent oils that meetFord’s specification. It is also acceptable to use an engine oil of recommended viscositygrade that meets API SN requirements and displays the API Certification Mark for gasolineengines.5Do not use oils labeled as API SN unless the label also display the API certification mark.These oils do not meet the requirements of your vehicles engine and emissions system.6Do not use supplemental engine oil additives. They are unnecessary and could lead toengine damage not covered by your Ford warranty.7Use the correct automatic transmission fluid. Transmission fluid requirements areindicated on the dipstick blade or the dipstick handle. Check the container to verify thefluid you are adding is of the correct type. Refer to your scheduled maintenance informationto determine the correct service interval.
Note:Automatic transmissions that require MERCON LV should only use MERCON LV fluid.Use of any fluid other than the recommended fluid may cause transmission damage.8Indicates only approximate dry-fill capacity. Some applications may vary based on coolersize and if equipped with an in-tank cooler. You should set the amount of transmissionfluid and fluid level by the indication on the dipstick’s normal operating range.9Fill to the proper capacity according to dipstick Type A. For correct dipstick type, SeeAutomatic Transmission Fluid Check (page 240).9Fill to the proper capacity according to dipstick Type B.
