coolant CADILLAC CTS V 2005 1.G Owner's Guide

(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 airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular maintenance.
(f)Lubricate all key lock cylinders. Lubricate all body
door hinges. Lubricate all hinges and latches, including
those for the hood, rear compartment, console door,
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.
(g)If you drive regularly under dusty conditions, the
lter may require replacement more often.
(h)Change automatic transmission uid and lter 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 high performance operation.If you do not use your vehicle under any of these
conditions, the uid and lter do not require changing.
(i)Drain, ush, and rell cooling system. This service
can be complex; you should have your dealer perform
this service. See Engine Coolant on page 5-25 for
what to use. Inspect hoses. Clean radiator, condenser,
pressure cap, and ller neck. Pressure test the
cooling system and pressure cap.
(k)A uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the uid level checked. Add uid if needed.
(l)Change uid if the vehicle is used for high
performance operation.
(m)Change uid whenever the vehicle has been driven
for 3,000 miles (5 000 km) with the transmission
temperature at 290°F (143°C) or higher without using
an auxiliary uid cooler. See Message Center (CTS-V)
on page 3-51andTransmission Fluid Hot Message
on page 3-55.
(n)If you drive regularly under dusty conditions, inspect
the lter at each engine oil change.
