3. Pull the air cleaner/filter box cover out and remove
the air filter element from the air filter box. If the
element is dirty, you should replace it. If the element
is only dusty, it may be cleaned by blowing
compressed air through it from the clean side.
Make sure you are away from your engine
compartment when cleaning the air filter with
compressed air.
4. Wipe all dust from inside the housing and inspect the
air cleaner and air inlet tube for cracks, cuts and
deterioration. The air inlet tube must be replaced if it
is damaged.
5. Install the air filter element, hose, hose clamp and
cover.
6. For vehicles equipped with the 2.2L engine, latch
the two clips. For vehicles equipped with the 2.0L
supercharged engine, replace the three screws.
Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid level.
A transaxle fluid leak is the only reason for fluid loss.
If a leak occurs, take the vehicle to retailer’s service
department and have it repaired as soon as possible.
You may also have your fluid level checked by your
retailer or service center when you have your oil
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:
• In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
• In hilly or mountainous terrain.
• When doing frequent trailer towing.
• Uses such as found in taxi, police or delivery
service.
