under which vehicle operations will occur. For the recom-
mended viscosity and quality grades, refer to “Fluids And
Lubricants” in “Technical Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE: A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and not
interpreted as a problem. Please check your oil level with
the engine oil indicator often during the break in period.
Add oil as required.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave the trans-
mission in PARK.
The foot operated parking brake is located below the lower
left corner of the instrument panel. To apply the park
brake, firmly push the park brake pedal fully. To release the
parking brake, pull the parking brake release handle. When the parking brake is applied with the ignition switch
ON, the “Brake Warning Light” in the instrument cluster
will illuminate.
NOTE:
•
When the parking brake is applied and the transmission
is placed in gear, the “Brake Warning Light” will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.
• This light only shows that the parking brake is applied.
It does not show the degree of brake application.

STARTING AND OPERATING 243

NOTE:Check the automatic transmission fluid level be-
fore towing.
Tow/Haul Mode
To reduce potential for automatic transmission overheat-
ing, activate TOW/HAUL mode when driving in hilly
areas, or select a lower gear range (using the Electronic
Range Select (ERS) shift control) on more severe grades.
Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission overheat-
ing, take the following actions:
City Driving
In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed. Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
Air Suspension System
To aid in attaching/detaching the trailer from the vehicle,
the air suspension system can be used. Refer to “Air
Suspension System” in “Starting And Operating” for fur-
ther information.
NOTE:
The vehicle must remain in the engine running
position while attaching a trailer for proper leveling of the
air suspension system.
SNOWPLOW
2500/3500 Models Only
Snowplow Prep Packages are available as a factory in-
stalled option. These packages include components neces-
sary to equip your vehicle with a snowplow.
306 STARTING AND OPERATING

9. Start the engine.
10. Press and hold the brake pedal.
11. Release the parking brake.
12. Shift the transmission into gear, release the brake pedal(and clutch pedal on manual transmissions), and check
that the vehicle operates normally.
NOTE: With electronic shift transfer case:
• Steps 3 and 4 are requirements that must be met before
pushing the button to shift out of NEUTRAL (N), and
must continue to be met until the shift has been com-
pleted. If any of these requirements are not met before
pushing the button or are no longer met during the shift,
the NEUTRAL (N) indicator light will flash continu-
ously until all requirements are met or until the button is
released.
• The ignition must be in the ON/RUN mode for a shift to
take place and for the position indicator lights to be
operable. If the ignition is not in the ON/RUN mode, the
shift will not take place and no position indicator lights
will be on or flashing.
• A flashing NEUTRAL (N) position indicator light indi-
cates that shift requirements have not been met.DRIVING TIPS
Driving On Slippery Surfaces
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the rear (driving)
wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and care-
fully whenever there is likely to be poor traction (ice,
snow, wet, mud, loose sand, etc.).
Driving Through Water
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and pre-
vent damage to your vehicle.
314 STARTING AND OPERATING

SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator 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” for
further information.Gasoline Engines:
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:
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 predominately at idle or
very low engine RPM’s. This type of vehicle use is consid-
ered Severe Duty.
Once A Month Or Before A Long Trip:
•
Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual
wear or damage
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering and automatic transmis-
sion, and fill as needed
• Check function of all interior and exterior lights
