VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle's battery:
²Disconnect the Ignition-Off Draw fuse (IOD) fuse
located in the Integrated Power Module, located in the
engine compartment. The IOD cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
²The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
²As an alternative to the above steps you may discon-
nect the negative cables from both batteries.
²Any time you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutesin the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
NOTE:When reinstalling the IOD fuse push firmly until
fully seated; the gauges in the instrument cluster will do
a full sweep when the ignition key is cycled to RUN. This
is a normal condition.
NOTE:When the vehicle is shipped from the factory,
the IOD fuse is in the up, or extracted position. If the
radio, interior lamps, keyless entry, or other features do
not work with the key OFF, check the position of the fuse
(or check to see if the fuse is blown) to ensure that it is
fully seated. When the IOD fuse is extracted, the instru-
ment cluster in the odometer window will display9NO

Fuel Selection(6.7L Turbo Diesel
Engine)Use good quality diesel fuel from a reputable supplier in your vehicle. Fed-
eral law requires that you must fuel this vehicle with Ultra Low Sulfur High-
way Diesel fuel (15 ppm Sulfur maximum) and prohibits the use of Low Sul-
fur Highway Diesel fuel (500 ppm Sulfur maximum) to avoid damage to the
emissions control system. For most year-round service, No. 2 diesel fuel
meeting ASTM specification D-975 Grade S15 will provide good perfor-
mance. If the vehicle is exposed to extreme cold (below 20ÉF or -7ÉC), or is
required to operate at colder-than-normal conditions for prolonged periods,
use climatized No. 2 diesel fuel or dilute the No. 2 diesel fuel with 50% No.
1 diesel fuel. This will provide better protection from fuel gelling or wax-
plugging of the fuel filters.This vehicle is fully compatible with biodiesel
blends up to 5% biodiesel meeting ASTM specification D-975.

EMISSION CONTROL SYSTEM MAINTENANCE
The Scheduled maintenance services, listed inbold type
in this section (Section 8) must be done at the times or
mileages specified to assure the continued proper func-
tioning of the emission control system. These, and all
other maintenance services included in this manual,
should be done to provide best vehicle performance and
reliability. More frequent maintenance may be needed for
vehicles in severe operating conditions, such as dusty
areas and very short trip driving.
Inspection and service also should be done anytime a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the emis-
sion control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part which has been
certified pursuant to U.S. EPA or, in the State of Califor-
nia, California Air Resources Board regulations.
MAINTENANCE SCHEDULES Ð 6.7L TURBO
DIESEL
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
²Check the engine oil level about 30 minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required. When refilling the washer fluid reservoir,

take some washer fluid and apply it to a cloth or towel
and wipe clean the wiper blades, this will help blade
performance.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the batteries and clean and tighten the termi-
nals as required.
²Check the fluid levels of coolant reservoir, brake
master cylinder, and transmission and transfer case (if
equipped), add as needed.
²Check all lights and all other electrical items for correct
operation.
²Drain water from the fuel filter.
²Check Filter MinderŸ (If Equipped). Replace air
cleaner filter element if necessary.At Each Oil Change
²Change the engine oil filter.
²Inspect the exhaust system.
²Inspect the brake hoses.
²Inspect the U-Joints (if equipped) and front suspension
components.
²Check the automatic transmission fluid level.
²Check the manual transmission fluid level.
²Check the coolant level, hoses, and clamps.
²Lubricate outer tie rod ends (4X4) models only.
²Lubricate Front Drive Shaft Fitting (4X4).
Inspection and service should also be performed anytime
a malfunction is observed or suspected. Retain all re-
ceipts.

Oil Change Indicator System
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it is
time to change your engine oil by displaying the words
ªOil Change Requiredº on your Electronic Vehicle Infor-
mation Center (EVIC). The engine oil change indicator
system is duty cycle based, which means the engine oil
change interval may fluctuate depending on your per-
sonal driving style. Driving styles such as frequent stop
and go type driving can increase the frequency of the
engine oil change. This is the result of more frequent
regeneration of the exhaust aftertreatment system, which
can decrease the life of the engine oil. Failure to change
the engine oil per the maintenance schedule can result in
internal engine damage.
For information on resetting the Oil Change Indicator
message, refer to ªOil Change Required ± If Equipped,ºunder ªSystem Status (EVIC Displays)º in the ªElectronic
Vehicle Information Center (EVIC)º Section of this
manual.
Perform Service Indicator
Your vehicle will require emissions maintenance at a set
interval. To help remind you when this maintenance is
due, the Electronic Vehicle Information Center (EVIC)
will display ªPerform Serviceº. When the ªPerform Ser-
viceº message is displayed on the EVIC it is necessary to
have the emissions maintenance performed. Emissions
maintenance includes replacing the Closed Crankcase
Ventilation (CCV) filter element, cleaning of the EGR
Cooler, and cleaning of the EGR Valve. The procedure for
clearing and resetting the9Perform Service9indicator
message is located in the appropriate Service Informa-
tion.
