4. Using the screwdriver or similar tool, push the ManualPark Release lever locking tab (just below the middle of
the lever) to the right.
5. While holding the locking tab in the disengaged position, pull the tether strap to rotate the lever rearward, until it
locks in place pointing towards the driver's seat. Release
the locking tab and verify that the Manual Park Release
lever is locked in the released position.
6. The vehicle is now out of PARK and can be towed. Release the parking brake only when the vehicle is
securely connected to a tow vehicle.
To Reset The Manual Park Release:
1. Push the locking tab to the right, to unlock the lever.
2. Rotate the Manual Park Release lever forward to its orig -
inal position, until the locking tab snaps into place to
secure the lever.
3. Pull gently on the tether strap to confirm that the lever is locked in its stowed position.
4. Re-install the access cover.IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the poten -
tial for overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase the engine idle speed while
preventing vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow down an impending
overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning
the A/C off can help remove this heat.
• You can also turn the temperature control to maximum heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement to
the radiator and aids in removing heat from the engine
cooling system.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change indi-
cator system. The oil change indicator system will remind
you that it is time to take your vehicle in for scheduled main -
tenance.
Based on engine operation conditions, the oil change indi -
cator message will illuminate. This means that service is
required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely hot or cold
ambient temperatures, and E85 fuel usage will influence
when the “Oil Change Required” message is displayed.
Severe Operating Conditions can cause the change oil
message to illuminate as early as 3,500 miles (5,600 km) since
last reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Instrument Cluster
Display” in “Getting To Know Your Instrument Panel”.
NOTE:
Under no circumstances should oil change intervals exceed
8,000 miles (13,000 km), twelve months or 350 hours of
engine run time, whichever comes first. The 350 hours of
engine run or idle time is generally only a concern for fleet
customers.
Severe Duty All Models
NOTE:
Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and off
road environment or is operated predominantly at idle, or
only very low engine RPM’s. This type of vehicle use is
considered Severe Duty.

Fluid Level Check — Eight-Speed Transmission
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required, therefore the transmis-
sion has no dipstick. An authorized dealer can check your
transmission fluid level using special service tools.
If you notice fluid leakage or transmission malfunction, visit
an authorized dealer immediately to have the transmission
fluid level checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage. Fluid And Filter Changes — Eight-Speed Transmission
Under normal operating conditions, the fluid installed at the
factory will provide satisfactory lubrication for the life of the
vehicle.
Routine fluid and filter changes are not required. However,
change the fluid and filter if the fluid becomes contaminated
(with water, etc.), or if the transmission is disassembled for
any reason.
Rear Axle And 4x4 Front Driving Axle Fluid Level
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected. If
gear oil leakage is suspected inspect the fluid level. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information. This inspection should be made with
the vehicle in a level position.
For all 2500/3500 Model axles, the fluid level should be 1/
4 in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole on the
9.25 in front, 11.5 in rear axle, and 12.0 in rear axle.
CAUTION!
If a transmission fluid leak occurs, visit an authorized
dealer immediately. Severe transmission damage may
occur. An authorized dealer has the proper tools to adjust
the fluid level accurately.

Compass Settings — If Equipped
After pressing the “Compass Settings” button on the touchscreen, the following settings will be available:Setting Name Selectable Options
Variance 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
NOTE:
• Compass Variance is the difference between Magnetic North and Geographic North. To compensate for the differences the variance should be set for the zone where the vehicle is driven, per the zone map. Once properly set, the compass will auto -
matically compensate for the differences, and provide the most accurate compass heading.
• Keep magnetic materials away from the top of the instrument panel, such as iPod's, Mobile Phones, Laptops and Radar Detectors. This is where the compass module is located, and it can cause interference with the compass sensor, and it may
give false readings.
Perform Compass Calibration On
Off
NOTE:
Press the “Calibration” button on the touchscreen to change this setting. This compass is self-calibrating, which eliminates
the need to manually reset the compass. When the vehicle is new, the compass may appear erratic until it is calibrated. You
may also calibrate the compass by pressing the “ON” button on the touchscreen and completing one or more 360-degree
turns (in an area free from large metal or metallic objects). The compass will now function normally.
