DEALER SERVICE — 6.7L DIESEL
ENGINE
Your authorized dealer has the qualified ser-
vice personnel, special tools, and equipment
to perform all service operations in an expert
manner. Service Manuals are available which
include detailed service information for your
vehicle. Refer to these Service Manuals be-
fore attempting any procedure yourself.
NOTE:
Intentional tampering with emissions control
systems may void your warranty and could
result in civil penalties being assessed
against you.
WARNING!
You can be badly injured working on or
around a motor vehicle. Only do service
work for which you have the knowledge
and the proper equipment. If you have any
doubt about your ability to perform a ser-
vice job, take your vehicle to a competent
mechanic.
Engine Air Cleaner Filter
CAUTION!
All air entering the engine intake must be
filtered. The abrasive particles in unfil-
tered air will cause rapid wear to engine
components.
WARNING!
The air induction system (air cleaner,
hoses, etc.) provides a measure of protec-
tion. Do not remove the air induction sys-
tem (air cleaner, hoses, etc.) unless such
removal is necessary for repair or mainte-
nance. Make sure that no one is near the
engine compartment before starting the
vehicle with the air induction system (air
cleaner, hoses, etc.) removed. Failure to
do so can result in serious personal injury.
The condition of the air cleaner filter is moni-
tored by the Engine Control Module. The
“SERVICE AIR FILTER” message will display
in the instrument cluster when service is
required. Refer to “Instrument Cluster Dis-
play” in “Getting To Know Your Instrument
Panel” for further information.
The “SERVICE AIR FILTER” message could
be displayed periodically. This is because
engine air flow requirements change based
on driving conditions. As the filter becomes
more restrictive and air flow requirements
increase the “SERVICE AIR FILTER” mes-
sage will be displayed. The message may not
be displayed in subsequent drive cycles if the
same conditions are not met. The air filter
element should be replaced within 250 miles
(402 km) from the first time this message is
displayed to ensure proper engine operation
during all driving conditions.
CAUTION!
Driving with a restricted air filter can
cause engine damage. Driving in dusty
environments for extended periods will
lead to rapid air filter plugging. Action
should be taken as soon as the “SERVICE
AIR FILTER” message is displayed.
