There are three types of maintenance
intervals for general vehicle environments:
On-Highway, City and Severe Service. In
all applications, monitoring miles
(kilometers) and time and when the engine
is due for an oil change determine the
actual interval. When the engine oil change
is required before the truck lubrication
interval, perform the lubrication at the
same time in order to reduce your vehicle
’s
time out of service.
Air Brake Adjustment WARNING: Failure to maintain
proper air brake adjustment can result
in reduction or loss of braking ability.
A qualified service technician, keeping to
the instructions in the service manual,
should perform air brake inspection and
adjustment or repairs.
Cam Brakes - Automatic Slack
Adjusters WARNING: Do not manually adjust
the automatic slack adjusters to correct
excessive push rod stroke as it may result
in reduced brake effectiveness and a
vehicle crash. Excessive push rod stroke
indicates that a problem exists with the automatic adjuster, with the installation
of the adjuster, or with foundation brake
components that manual adjustment
does not remedy. Seek service from a
qualified facility for excessive push rod
stroke.
Inspect standard air brakes equipped with
automatic slack adjusters for proper brake
adjustment as listed in the maintenance
schedule charts.
However, inspect the brakes more
frequently when subjecting them to heavy
use or adverse operating conditions such
as:
• Frequent brake applications while fully
loaded.
• Operation on hilly or mountainous
terrain.
• Frequent operation on dirt, gravel or
mud.
Some aftermarket brake linings also
require more frequent inspections.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals. Check Every Month
Air filter restriction gauge. 1
Engine oil level.
Fuel and water separator. Drain if necessary, or if indicated by the information display. 1
Function of all interior and exterior lights.
Holes and slots in the tail pipe to make sure they are functional and clear of debris. 1

Multi-point Inspection
In order to keep your vehicle running right,
it is important to have the systems on your
vehicle checked regularly. This can help
identify potential issues and prevent major
problems. We recommend having the
following multi-point inspection performed
at every scheduled maintenance interval
to help make sure your vehicle keeps
running great.Multi-point Inspection

Be sure to ask your dealership service
advisor or technician about the multi-point
vehicle inspection. It is a comprehensive
way to perform a thorough inspection of
your vehicle. Your checklist gives you
immediate feedback on the overall
condition of your vehicle. NORMAL SCHEDULED
MAINTENANCE
Intelligent Oil-Life Monitor™ -
Diesel Engine Only
Your diesel engine has an Intelligent
Oil-Life Monitor that determines when you
should change the engine oil based on how
you use your vehicle. By using several
important factors in its calculations, the
monitor helps reduce the cost of owning
your vehicle and reduces environmental
waste at the same time.
