If brake failure is indicated, immediate repair is necessary
and continued operation of the vehicle in this condition is
dangerous.
Acceleration which causes the rear wheels to slip for a
period of time may result in the red brake light illumi-
nating and a brake switch code being set on ABS
equipped vehicles. Depressing the brake pedal should
extinguish the red brake light.

the vehicle.
20. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.If the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.
The trip odometer shows individual trip mileage. To

NOTE:Failure to perform maintenance service at the
specified intervals as outlined in theMaintenance
Schedulesmay void provisions of your Vehicle Warranty.
CAUTION!
To maintain your vehicle safely follow these guide-
lines:
²Watch your vehicle's mileage and check yourMainte-
nance Schedulesregularly for required servicing. Ex-
cessive wear or damage to certain vehicle components
can result if required services are not performed.
²If you have your vehicle undercoated, inspect for
undercoating material on the propeller shafts. Such
material could cause the shafts to become unbalanced
and result in drivetrain vibrations. Remove any under-
coating with solvent.
²If you have your vehicle undercoated, make sure no
undercoating material is sprayed on the exhaust sys-
tem or components of the seat belt system.
NOTE:It is not possible for the manufacturer and
Cummins, Inc. to anticipate every possible circumstance
that can involve a potential hazard.
WARNING!
To maintain your vehicle safely and avoid personal
injury, follow these guidelines:
²Never spray or pour diesel fuel, flammable liquid or
starting fluids (ether) into the air cleaner canister, air
intake piping or turbocharger inlet in an attempt to
start the vehicle.

Do not remove the top of the air filter housing to
inspect the filter element on your diesel engine under
normal operating conditions.
The clear plastic housing on the Filter MinderŸ allows
you to view the amount of air pressure drop across the
filter element. It consists of a diaphragm and a calibrated
spring sealed inside the plastic housing. As the aircleaner filter becomes clogged and air pressure drop
across the filter element increases, a yellow disc travels
along a graduated scale on the side of the Filter
MinderŸ.
The yellow disc will always show the greatest restriction
experienced by the filter element. When the disc reaches
the red zone, the filter element may need to be replaced.
There is no other time or mileage interval for changing
the air cleaner filter element.
If the vehicle experiences a sudden loss of engine power
when being driven in heavy snow or rain or when
plowing snow, check the Filter MinderŸ
²If the Filter MinderŸ is showing a plugged filter, the
filter should be visually inspected for snow/ice build
up or extreme water saturation.
²If any of these conditions exist, the filter element
should be replaced.

EMISSION CONTROL SYSTEM MAINTENANCE
The ªScheduledº maintenance services, listed inbold
typein this section (Section 8) must be done at the times
or mileages specified to assure the continued proper
functioning 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 any time 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.

NOTE:Most vehicles are operated under the conditions
listed for Schedule9B9.
Second is ScheduleªAº. It is for vehicles that are not
operated under any of the conditions listed under Sched-
ule9B9.
Use the schedule that best describes your driving condi-
tions. Where time and mileage are listed, follow the
interval that occurs first.
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 15 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.
²Drain water from the fuel filter.
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.
