DEALER SERVICE — 6.7L
DIESEL ENGINE
Your authorized dealer has the qualified
service personnel, special tools, and equip
-
ment to perform all service operations in an
expert manner. Service Manuals are avail
-
able which include detailed service informa
-
tion for your vehicle. Refer to these Service
Manuals before attempting any procedure
yourself.

Intentional tampering with emissions control

Engine Air Cleaner Filter
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
Display” in “Getting To Know Your Instru
-
ment 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”
message 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 condi
-
tions.
If the vehicle experiences a sudden loss of
engine power while being driven in heavy
snow or rain, or when plowing snow, and/or
the “SERVICE AIR FILTER” message is
displayed on the instrument cluster along
with a chime that repeats every 60 seconds,
visually inspect the air filter for snow/ice
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
service job, take your vehicle to a
competent mechanic.
WARNING!
The air induction system (air cleaner,
hoses, etc.) provides a measure of
protection. Do not remove the air
induction system (air cleaner, hoses, etc.)
unless such removal is necessary for repair
or maintenance. 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.
CAUTION!
All air entering the engine intake must be
filtered. The abrasive particles in
unfiltered air will cause rapid wear to
engine components.
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.
