Note:The grille cover must be installed inextremely cold conditions below 10.4°F(-12°C) to prevent possible engine damage.
Usage Guidelines
The winter grille cover should only be usedwhile operating your vehicle in extremelycold temperatures or in heavy snow forextended periods of time. In thesetemperatures, the vehicle does not needa large amount of air to properly cool theengine. During periods of operation whenmore airflow is required to cool the vehicle,the winter grille cover should not be used.
The following usage guidelines will allowadequate airflow for proper radiator andair cooler performance:
•Do not use the cover whentemperatures are above 50.0°F (10°C).Use of the cover in these conditionscould cause your vehicle to overheat.Remove the cover if the vehicleoverheats.
•Do not use the cover above 32.0°F(0°C) if towing a trailer. Your vehiclemay overheat if the cover is used whiletowing a trailer.
•Do not modify the cover.
Installation Instructions
Installation and removal instructions areincluded in the winter grille cover package.Refer to the usage guidelines tounderstand when to use the cover.
The cover will seem undersized during thefirst installation, which is normal. The coverstretches during installation to ensure atight fit. The first installation is bestperformed when the grille cover is warm.

PRECAUTIONS - 7.3L
The functional operation of somecomponents and systems can be affectedat temperatures below approximately-13°F (-25°C).
BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). Duringthis time, your vehicle may exhibit someunusual driving characteristics.
Avoid driving too fast during the first1,000 mi (1,600 km). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Drive your new vehicle at least 1,000 mi(1,600 km) before towing a trailer. Makesure you use the specified engine oil. SeeEngine Oil Capacity and Specification(page 296).
Do not add friction modifier compoundsor special break-in oils during the first fewthousand miles (kilometers) of operation.These additives may prevent piston ringseating.

VEHICLE INSPECTION
INFORMATION
To make sure your vehicle is ready tooperate, conduct a pre-trip inspection atthe beginning of each work period. Followthe steps listed in this section to verify aproper vehicle inspection procedure.
WARNING: Exercise great cautionwhen working on a vehicle equipped withan automatic fan clutch. The fan startsin motion only after the engine coolantreaches a predetermined temperatureor the refrigerant pressure (if equippedwith air conditioning) reaches apredetermined setting. The fan starts atthis point with no advance warning.Never reach near, or permit objects toprotrude into, the fan blade radius whilethe engine is running as this could resultin vehicle damage, personal injury ordeath.
WARNING: Do not operate thevehicle if any suspension conditionslisted in the following charts are evident.Loss of steering or suspension couldresult in property damage, personal injuryor death.
WARNING: If a wheel must bechanged, obtain expert tire service help.Mounting and un-mounting of tiresshould only be performed by a qualifiedtechnician using necessary safetyprocedures and equipment, otherwisethe result could be property damage,personal injury or death.
Note:Always make sure you apply theparking brake before starting the engine.
Engine compartment (with engine off)
Use the dipstick to verify the oil level is in the proper operatingrange. See Engine Oil Dipstick (page 227).Engine oil
Look through the plastic reservoir and verify the coolant levelis within the proper operating range. Do not remove thepressure cap until the coolant has cooled. See EngineCoolant Check (page 238).
Engine coolant
Verify that the fluid level is in the proper operating range. SeePower Steering Fluid Check (page 246).Power steering fluid
Remove the master cylinder caps and inspect the fluid level.See Brake Fluid Check (page 245).Brake fluid

Engine compartment (with engine off)
Inspect for glazing, fraying or cracking. There should be nomore than 5-7 cracks per rib, per 1 in (2.5 cm)Belts (fan, alternator,water pump and airconditioningcompressor)
Inspect for signs of fluid puddles or dripping fluid on theground under the engine, or the underside of the engine.Fluid leaks
Inspect for debris that may have collected on the HVAC airinlet grille or inside the exterior module as this may reducesystem performance.
HVAC air inlet
Engine starting (with parking brake applied)
Before entering the cab, verify that the vehicle is equippedwith spare electrical fuses (if used), three red reflectivetriangles, a properly charged and rated fire extinguisher andwheel chocks.
Safety and emergencyequipment
Walk around the vehicle and verify all steps and grab handles,inside and out (as well as behind), are tight and clean. Useextreme caution and a three-point stance at all times.
Inspect door latches for proper closing, latching and locking.
Set the parking brake. Make sure the gearshift lever is inneutral (N) or park (P) (if equipped with a park position).Starting the engine
Diesel engine: Turn the key to the on position. Turn the keyto start when the wait to start indicator light in the instrumentcluster turns off.
Gasoline engine: Turn the key to start, and then release itas soon as the engine starts.
Verify pressure builds to normal operating range.Engine oil pressure
A tone indicating low air pressure should sound immediatelyafter the engine starts but before the compressor has built-up pressure. The tone should stop when the air pressurereaches 70 psi (483 kPa). Let the air pressure build togoverned cutout pressure, which should occur between115–130 psi (793–896 kPa).
Low air pressure warningtone (if equipped with anair compressor)
Press the accelerator and verify that it operates smoothly,without any binding or irregular feel. Release the pedal andverify the engine returns to idle speed immediately.
