(c) Visually inspect hoses and have them replaced if
they are cracked, swollen or deteriorated. Inspect
all pipes, fittings and clamps; replace with genuine
Saturn parts as needed. To help ensure proper
operation, a pressure test of the cooling system and
pressure cap and cleaning the outside of the radiator
and air conditioning condenser is recommended at least
once a year.
(d) Visually inspect wiper blades for wear or cracking.
Replace blade inserts that appear worn or damaged
or that streak or miss areas of the windshield.
(e) Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced. Also look for any opened or broken air bag
coverings, and have them repaired or replaced. (The air
bag system does not need regular maintenance.)
(f) Lubricate all key lock cylinders, door hinges and
latches, hood hinges and latches, glove box hinges,
sunroof (if equipped) and any folding seat hardware.
More frequent lubrication may be required when
exposed to a corrosive environment. Applying silicone
grease on weatherstrips with a clean cloth will make
them last longer, seal better and not stick or squeak.
6-8
(g) Check system for interference or binding and for
damaged or missing parts. Replace parts as needed.
Replace any components that have high effort or
excessive wear. Do not lubricate accelerator or cruise
control cables.
(h) Change automatic transaxle fluid and filter 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 you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
(i) Drain, flush and refill cooling system. See Engine
Coolant on page 5-23 for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap and filler neck.
Pressure test the cooling system and pressure cap.
(j) A fluid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired and
the fluid level checked. Add fluid if needed.
(k) Or every 12 months, whichever occurs first. If you
drive regularly under dusty conditions, the filter may
require replacement more often.
