Air Cleaner
To check or replace the air filter, remove the four screws
and pall off the cover. Pull
out the filter.

Operating the engine with the air cleaner off can
cause you or others to
be burned. The air cleaner
not only cleans the air, it stops flame if the,engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner off.
I NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain.
regularly reaches
90°F (32” C) or higher.
0 When doing
frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If
YOU do not use your vehicle under any of these
conditions, the fluid
and filter do not require changing.
See “Scheduled Maintenance Services” in the Index.
