CADILLAC STS V 2007 1.G Owners Manual

Finish Care
Occasional waxing or mild polishing of the vehicle
by hand may be necessary to remove residue
from the paint nish. Approved cleaning products
can be obtained from your dealer. SeeVehicle
Care/Appearance Materials on page 484.
Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint
nish may damage it. Use only non-abrasive
waxes and polishes that are made for a
basecoat/clearcoat paint nish on your vehicle.
The vehicle has a basecoat/clearcoat paint
nish. The clearcoat gives more depth and gloss
to the colored basecoat. Always use waxes
and polishes that are non-abrasive and made for a
basecoat/clearcoat paint nish.
Foreign materials such as calcium chloride and
other salts, ice melting agents, road oil and
tar, tree sap, bird droppings, chemicals from
industrial chimneys, etc., can damage the vehicle’s
nish if they remain on painted surfaces. Wash
the vehicle as soon as possible. If necessary, use
non-abrasive cleaners that are marked safe for
painted surfaces to remove foreign matter.Exterior painted surfaces are subject to aging,
weather, and chemical fallout that can take their
toll over a period of years. To help keep the
paint nish looking new, keep the vehicle in a
garage or covered whenever possible.
Windshield and Wiper Blades
If the windshield is not clear after using the
windshield washer, or if the wiper blade chatters
when running, wax, sap, or other material may
be on the blade or windshield.
Clean the outside of the windshield with a glass
cleaning liquid or powder and water solution.
The windshield is clean if beads do not form when
it is rinsed with water.
Grime from the windshield will stick to the wiper
blades and affect their performance. Clean
the blade by wiping vigorously with a cloth soaked
in full-strength windshield washer solvent. Then
rinse the blade with water.
Check the wiper blades and clean them as
necessary; replace blades that look worn.
481

Aluminum or Chrome-Plated Wheels
Your vehicle may have either aluminum or
chrome-plated wheels.
Keep the wheels clean using a soft clean cloth
with mild soap and water. Rinse with clean water.
After rinsing thoroughly, dry with a soft clean
towel. A wax may then be applied.
Notice:If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or
cleaners that contain acid on aluminum or
chrome-plated wheels, you could damage the
surface of the wheel(s). The repairs would
not be covered by your warranty. Use
only GM-approved cleaners on aluminum or
chrome-plated wheels.
The surface of these wheels is similar to the
painted surface of your vehicle. Do not use strong
soaps, chemicals, abrasive polishes, abrasive
cleaners, cleaners with acid, or abrasive cleaning
brushes on them because you could damage
the surface. Do not use chrome polish on
aluminum wheels.Notice:Using chrome polish on aluminum
wheels could damage the wheels. The repairs
would not be covered by your warranty.
Use chrome polish on chrome wheels only.
Use chrome polish only on chrome-plated wheels,
but avoid any painted surface of the wheel, and
buff off immediately after application.
Notice:If you drive your vehicle through an
automatic car wash that has silicone carbide
tire cleaning brushes, you could damage
the aluminum or chrome-plated wheels. The
repairs would not be covered by your warranty.
Never drive a vehicle equipped with aluminum
or chrome-plated wheels through an
automatic car wash that uses silicone carbide
tire cleaning brushes.
Do not take your vehicle through an automatic car
wash that has silicone carbide tire cleaning
brushes. These brushes can also damage the
surface of these wheels.
482

Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on your vehicle may damage the
paint nish and/or tires. When applying a tire
dressing, always wipe off any overspray
from all painted surfaces on your vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body
repair shop applies anti-corrosion material to parts
repaired or replaced to restore corrosion
protection.
Original manufacturer replacement parts will
provide the corrosion protection while maintaining
the warranty.
Finish Damage
Any stone chips, fractures or deep scratches in
the nish should be repaired right away. Bare
metal will corrode quickly and may develop into
major repair expense.
Minor chips and scratches can be repaired with
touch-up materials available from your dealer.
Larger areas of nish damage can be corrected in
your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and
dust control can collect on the underbody. If these
are not removed, corrosion and rust can develop
on the underbody parts such as fuel lines,
frame, oor pan, and exhaust system even though
they have corrosion protection.
At least every spring, ush these materials from the
underbody with plain water. Clean any areas where
mud and debris can collect. Dirt packed in close
areas of the frame should be loosened before being
ushed. Your dealer or an underbody car washing
system can do this for you.
483

Chemical Paint Spotting
Some weather and atmospheric conditions can
create a chemical fallout. Airborne pollutants can
fall upon and attack painted surfaces on the
vehicle. This damage can take two forms: blotchy,
ring-shaped discolorations, and small, irregular
dark spots etched into the paint surface.
Although no defect in the paint job causes this, GM
will repair, at no charge to the owner, the surfaces
of new vehicles damaged by this fallout condition
within 12 months or 12,000 miles (20 000 km) of
purchase, whichever occurs rst.

Vehicle Identication
Vehicle Identication Number (VIN)
This is the legal identier for your vehicle. It
appears on a plate in the front corner of the
instrument panel, on the driver side. You can see
it if you look through the windshield from outside
your vehicle. The VIN also appears on the Vehicle
Certication and Service Parts labels and the
certicates of title and registration.
Engine Identication
The eighth character in the VIN is the engine
code. This code helps you identify your vehicle’s
engine, specications, and replacement parts.
Service Parts Identication Label
This label is on your spare tire cover. It is
very helpful if you ever need to order parts. The
label has the following information:
Vehicle Identication Number (VIN)
Model designation
Paint information
Production options and special equipment
Do not remove this label from the vehicle.
485

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 78.
Headlamp Wiring
The headlamp wiring is protected by fuses in the
fuse block. An electrical overload will cause
the lamps to turn off. If this happens, have your
headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal circuit breaker. If the wiper motor
overheats due to heavy snow, the wipers will stop
until the motor cools and will then restart.
486

Power Windows and Other Power
Options
Circuit breakers protect the power windows and
power seats. When the current load is too
heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is xed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses,
circuit breakers and fusible thermal links.
This greatly reduces the chance of res caused by
electrical problems.Look at the silver-colored band inside the fuse. If
the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new one of
the identical size and rating. If a fuse should
blow, see your dealer for service immediately.
If you ever have a problem on the road
and don’t have a spare fuse, you can borrow
one that has the same amperage. Just pick some
feature of your vehicle that you can get along
without – like the radio or cigarette lighter – and
use its fuse, if it is the correct amperage. Replace
it as soon as you can.
The fuses are located in three fuse blocks.
One is located in the engine compartment, on the
passenger’s side of the vehicle, and the other
two are located under the rear seat on both the
driver’s and passenger’s side of the vehicle.
487

Underhood Fuse Block
488

The underhood fuse block is located in the front of
the engine compartment on the passenger’s
side of the vehicle. SeeEngine Compartment
Overview on page 373for more information
on location and removal procedure for the front
compartment underhood sights shields.
To access the fuses, push in the tabs located on
each side of the fuse block cover, then lift the
cover off.
