Engine Air Cleaner Filter
WARNING!
The air induction system (air cleaner, hoses, etc.) pro-
vides 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.
The condition of the air cleaner filter is monitored by the
Engine Control Module. The “SERVICE AIR FILTER”
message will display in the instrument cluster when ser-
vice is required. Refer to “Instrument Cluster Display” 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” 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 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 FIL-
TER” message is displayed.
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” mes-
sage is displayed on the instrument cluster along with a
chime that repeats every 60 seconds, visually inspect the air
filter for snow/ice build up or extreme water saturation. If
