How To Inspect The Engine Air Cleaner/ Filter - Hummer H2 2010 Owner's Manual

When to Inspect the Engine Air Cleaner/
Filter
If the vehicle is equipped with an air filter restriction
indicator, it lets you know when the engine air cleaner/
filter needs to be replaced. On vehicles with a restriction
indicator, you should inspect the air filter restriction
indicator at every oil change and replace the engine air
cleaner/filter when the indicator tells you to.
On vehicles without an air filter restriction indicator, you
should inspect the air cleaner/filter at every oil change
and replace it at the first oil change after 160 000 km
(100,000 miles). See Scheduled Maintenance on
page 7 3 for more information.
How to Inspect the Engine Air Cleaner/
Filter
Vehicles With an Air Filter Restriction
Indicator
Locate the air filter restriction indicator on the engine air
duct. When the indicator turns black or is in the red/
orange change zone, replace the filter and reset the
indicator. See Inspecting the Engine Air Cleaner/Filter
and Resetting the Air Filter Restriction Indicator later in
this section for further instructions.
Vehicles Without an Air Filter Restriction
Indicator
To inspect the air cleaner/filter, remove it from the
vehicle and lightly shake the filter to release loose dust
and dirt. If the engine air cleaner/filter remains caked
with dirt, a new filter is required. See Inspecting the
Engine Air Cleaner/Filter and Resetting the Air Filter
Restriction Indicator later in this section for further
instructions.
