CHEVROLET 2010 HHR - Manual (Page 321)

To inspect or replace the filter, do the following:
1. Remove the screws that hold the housing and
cover together and lift off the cover.
2. Inspect or replace the engine air cleaner/filter.
3. Reverse the steps to reinstall the system. Be sure
to reinstall the housing tightly.
{ WARNING:
Operating the engine with the air cleaner/filter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
flames if the engine backfires. If it is not there and
the engine backfires, you could be burned. Do not
drive with it off, and be careful working on the
engine with the air cleaner/filter off.
Notice: If the air cleaner/filter is off, a backfire can
cause a damaging engine fire. And, dirt can
easily get into the engine, which will damage it.
Always have the air cleaner/filter in place when you
are driving.
Automatic Transmission Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take your vehicle to a
dealer/retailer and have it repaired as soon as possible.
Change the fluid and filter at the intervals listed in
the Maintenance Schedule. See Scheduled Maintenance
on page 7-3. Be sure to use the transmission fluid
listed in Recommended Fluids and Lubricants on
page 7-10.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages
may not be covered by the vehicle’s warranty.
Always use the automatic transmission fluid listed
in Recommended Fluids and Lubricants on
page 7-10.
