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 helps
to stop flame 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 your engine, which will damage it.
Always have the air cleaner/filter in place when you
are driving.
Automatic Transmission Fluid
(Except Allison Transmission
®
)
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 50,000 miles
(83 000 km) if the vehicle’s GVWR is over 8,600 or 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.
If your vehicle’s GVWR is not over 8,600 and you do
not use your vehicle under any of these conditions,
change the fluid and filter every 100,000 miles
(166 000 km).
