ECONOMICAL DRIVING
Your fuel economy is affected by severalthings, such as how you drive, theconditions you drive under, and how youmaintain your vehicle.
You may improve your fuel economy bykeeping these things in mind:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds withoutstopping.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Close the windows for high-speeddriving.
•Drive at reasonable speeds. Travelingat 55 mph (90 km/h) uses 15% lessfuel than traveling at 65 mph(105 km/h).
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
Avoid these actions; they reduce your fueleconomy:
•Sudden accelerations or hardaccelerations.
•Warm up your vehicle on coldmornings.
•Use the air conditioner.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal whiledriving.
•Carry unnecessary weight.Approximately 1 mpg [0.4 km/L] is lostfor every 400 lb (180 kg) of weightcarried.
•Driving with the wheels out ofalignment.
Conditions
•Adding certain accessories to yourvehicle may reduce fuel economy. Forexample bug deflectors, rollbars, lightbars, running boards, ski racks orluggage racks.
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures during the first 5–10 mi(12–16 km) of driving.
•Driving on flat terrain offers improvedfuel economy as compared to drivingon hilly terrain.
•Transmissions give their best fueleconomy when operated in the topcruise gear and with steady pressureon the gas pedal.
COLD WEATHER
PRECAUTIONS - 6.7L DIESEL
Winter Grille Cover (If Equipped)
The winter grille cover enhances heaterperformance and will reduce the amountof time it takes to warm the inside of yourvehicle in extremely cold conditions below-0.4°F (-18°C).
The winter grille cover installs over theoutside of the front grille and restricts theair flowing to the engine compartment bycovering the radiator grille openings.

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.
