Chevrolet impala 2000 ユーザーズマニュアル

The passenger compartment air filter is located
underneath the hood just below the windshield wiper
arm on the passenger’s side of the vehicle (underneath
the air inlet grille).

The filter traps most of the pollen from air entering the
module. Like your engine’s air cleaner/ filter, it may
need to be changed periodically. For information on how
often to change the passenger compartment air filter, see
“Maintenance Schedule” in the Index.

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:
D In heavy city traffic where the outside temperature

regularly reaches 90

_F (32_C) or higher.

D In hilly or mountainous terrain.
D When doing frequent trailer towing.
D 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 at 100,000 miles
(166 000 km).
