6-19 Installing the Engine Cover
1. Lift the engine cover into the vehicle and slide it all
the way forward. Make sure the rubber seal is over
the latches.
2. Install the two bolts at the engine cover.
3. Put the heater duct over the engine cover studs. Push
up on the duct gently until it snaps into place.
4. Reconnect the electrical connectors.
5. Reconnect the AM radio ground strap.
6. Install the engine cover extension by gently
squeezing the sides and sliding it into place.
Make sure all of the fastener clips engage and the
extension fits properly in place. Install and tighten
the two screws.
7. Install the two nuts to secure the extension in place.
Engine Air Cleaner/Filter
Refer to the Maintenance Schedule to determine when to
replace the engine air cleaner/filter and the crankcase
ventilation filter.
See ªScheduled Maintenanceº in the Index.
See ªEngine Compartment Overviewº in the Index for
more information on location.
To remove the engine air cleaner/filter, do
the following:
1. Unsnap both clips.
2. Remove the top.
3. Change the filter.
4. Snap both clips to secure the engine air cleaner/filter.
Be sure the engine air cleaner/filter lid is correctly
positioned to seal out dust and contaminants that are
harmful to your engine.

6-20
CAUTION:
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 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/filter off.
NOTICE:
If the air cleaner/filter 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/filter in place when
you're driving.
Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every 15,000 miles
(25 000 km) if the vehicle is mainly driven under one or
more of these conditions:

In heavy city traffic where the outside temperature
regularly reaches 90F (32C) or higher.

In hilly or mountainous terrain.

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, change the fluid and filter every
50,000 miles (83 000 km).
See ªScheduled Maintenance Servicesº in the Index.

Scheduled Maintenance

Short Trip/City Definition
Follow the Short Trip/City Scheduled Maintenance if
any one of these conditions is true for your vehicle:

Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.

Most trips include extensive idling (such as frequent
driving in stop
-and-go traffic).

Most trips are through dusty areas.

You frequently tow a trailer or use a carrier on top of
your vehicle.

If the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons you should follow this schedule
if you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.
