128STARTING AND OPERATING
ENGINE BREAK-IN RECOMMENDATIONS —
DIESEL ENGINE
The Cummins® Turbo Diesel engine does not
require a break-in period due to its construction.
Normal operation is allowed, providing the
following recommendations are followed:
Warm up the engine before placing it under
load.
Do not operate the engine at idle for prolonged
periods.
Use the appropriate transmission gear to
prevent engine lugging.
Observe vehicle oil pressure and temperature
indicators.
Check the coolant and oil levels frequently.
Vary throttle position at highway speeds when
carrying or towing significant weight.
NOTE:Light duty operation such as light trailer towing or
no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy
and power may be seen at this time.
For additional vehicle break-in requirements
Úpage 186. Because of the construction of the Cummins®
Turbo Diesel engine, engine run-in is enhanced by
loaded operating conditions which allow the
engine parts to achieve final finish and fit during
the first 6,000 miles (10,000 km).
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied. Also, be certain to
leave the transmission in PARK.
The foot operated parking brake is located below
the lower left corner of the instrument panel. To
apply the parking brake, firmly push the parking
brake pedal fully. To release the parking brake, pull
the parking brake release handle.

Parking Brake Release
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.
When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade. Apply
the parking brake before placing the gear selector
in PARK, otherwise the load on the transmission
locking mechanism may make it difficult to move
the gear selector out of PARK. The parking brake
should always be applied whenever the driver is
not in the vehicle.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
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 “Oil Change Due” in your instrument cluster
display. The engine oil change indicator system is
duty cycle based, which means the engine oil
change interval may fluctuate depending on your
personal driving style. Failure to change the engine
oil per the maintenance schedule can result in
internal engine damage.
An 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 an authorized dealer, the
message can be reset by referring to the steps
described under instrument cluster display
Úpage 89. For Gasoline Engines, under no circumstances
should oil change intervals exceed 8,000 miles
(13,000 km), 12 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.
For Diesel Engines, under no circumstances
should oil change intervals exceed 15,000 miles
(24,000 km) or 12 months, whichever comes first
or sooner if prompted by the oil change indicator
system.
NOTE:
It is recommended that every 3,000 miles
(4,800 km), check the engine oil level at least
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.
Severe service (high ambient temperature,
short trips, heavy loading, trailer towing,
off-road, or law enforcement use) may reduce
oil change intervals.
For Diesel Engines, configured with optional B20
capability are operated with greater than 5% levels
of biodiesel, the oil change interval must not
exceed 12,500 miles (20,000 km) or 400 hours,
whichever comes first under any circumstances.
See the Fuel Requirements section for more
information regarding operation with biodiesel
blend (B6-B20) fuel meeting ASTM specification
D-7467.
Perform Service Indicator — Diesel Engine
Your vehicle will require emissions maintenance at
a set interval. To help remind you when this
maintenance is due, the instrument cluster will
display “Perform Service”. When the “Perform
Service” message is displayed on the instrument
cluster it is necessary to have the emissions
maintenance performed. Emissions maintenance
may include replacing the Closed Crankcase
Ventilation (CCV) filter element. The procedure for
clearing and resetting the “Perform Service”
indicator message is located in the appropriate
Service Information.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.

(Continued)
CHECKING OIL LEVEL
To ensure proper engine lubrication, the engine oil
must be maintained at the correct level. Check the
oil level at regular intervals, such as every fuel
stop. The best time to check the engine oil level is
about five minutes after a fully warmed up engine
is shut off.
Checking the oil while the vehicle is on level ground
will improve the accuracy of the oil level readings.
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the low
end of the range and MAX at the high end of the
range.
Crosshatched zone marked with dimples at the
MIN and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 qt (1 L) of oil when the reading is at the
low end of the dipstick range will raise the oil level
to the high end of the range marking.
ADDING WASHER FLUID
The fluid reservoir is located under the hood and
the fluid level should be checked at regular
intervals. Fill the reservoir with windshield washer
solvent only (not radiator antifreeze). When
refilling the washer fluid reservoir, take some
washer fluid and apply it to a cloth or towel and
wipe the wiper blades clean. This will help blade
performance.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or mixture
that meets or exceeds the temperature range of
your climate. This rating information can be found
on most washer fluid containers.After the engine has warmed up, operate the
defroster for a few minutes to reduce the
possibility of smearing or freezing the fluid on the
cold windshield. Windshield washer solution used
with water as directed on the container, aids
cleaning action, reduces the freezing point to avoid
line clogging, and is not harmful to paint or trim.MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a maintenance-free
battery. You will never have to add water, and
periodic maintenance is not required.
NOTE:Replacement batteries should both be of equal
capacity to prevent damage to the vehicle's
charging system.
CAUTION!
Overfilling or underfilling the crankcase will
cause oil aeration or loss of oil pressure. This
could damage your engine.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling or
working around the washer solution.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes or
on skin, flush the area immediately with large
amounts of water Ú
page 334.

SERVICING AND MAINTENANCE371
(Continued)
To guarantee optimum performance of the system,
keep the surfaces of the charge air cooler,
condenser and radiator clean and free of debris.
Periodically check the hoses leading to and from
the charge air cooler for cracks or loose clamps
resulting in loss of pressure and reduced engine
performance.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically Ú
page 344.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood service
or immediately if the Brake System Warning Light
indicates system failure.
If necessary, add fluid to bring level within the
designated marks on the side of the reservoir of
the brake master cylinder. Be sure to clean the top
of the master cylinder area before removing cap.
With disc brakes the fluid level can be expected to
fall as the brake linings wear. However, an
unexpected drop in fluid level may be caused by a
leak and a system check should be conducted.
For further information Ú page 421.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.
WARNING!
Use only manufacturer's recommended brake
fluid Úpage 421. Using the wrong type of
brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in an open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.
Do not allow petroleum based fluid to contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
WARNING!

AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends against
using any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an
engineered product and its performance may be
impaired by supplemental additives. Therefore, do
not add any fluid additives to the transmission. The
only exception to this policy is the use of special
dyes for diagnosing fluid leaks in 6-speed
transmissions. Avoid using transmission sealers as
they may adversely affect seals.
Fluid Level Check — 8-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 transmission 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 Level Check — 6-Speed Transmission
It is best to check the fluid level when the
transmission is at normal operating temperature
(158-176°F / 70-80°C). This normally occurs
after at least 15 miles (25 km) of driving. At normal
operating temperature the fluid cannot be held
comfortably between the fingertips. You can read
the transmission sump temperature in the
instrument cluster screen Ú page 89.
Use the following procedure to check the
transmission fluid level properly:

1. Monitor the transmission temperature using the instrument cluster display, and operate
the vehicle as required to reach the normal
operating temperature. If the transmission is
not functioning properly, or the vehicle cannot be driven, see the following Note and Caution
about checking the fluid level at colder
temperatures.

2. Park the vehicle on level ground.
3. Run the engine at normal idle speed for at least 60 seconds, and leave the engine
running for the rest of this procedure.
4. Fully apply the parking brake, and press the brake pedal.
5. Place the gear selector momentarily into each gear position (allowing time for the
transmission to fully engage in each position),
ending with the transmission in PARK.
6. Remove the dipstick, wipe it clean and reinsert it until seated.
7. Remove the dipstick again and note the fluid level on both sides. The fluid level reading is
only valid if there is a solid coating of oil on
both sides of the dipstick. Note that the holes
in the dipstick will be full of fluid if the actual
level is at or above the hole. The fluid level
should be between the “HOT” (upper)
reference holes on the dipstick at normal
operating temperature. If the fluid level is low,
add fluid through the dipstick tube to bring it to
the proper level. Do not overfill. Use ONLY the
specified fluid Ú page 421. After adding any
quantity of oil through the dipstick tube, wait a
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.
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.
