CADILLAC STS 2011 1.G Owners Manual

Black plate (111,1)Cadillac STS Owner Manual - 2011
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 finish looking new, keep
the vehicle garaged or covered whenever possible.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However, chrome polish may be used on
chrome or stainless steel trim, if necessary.
Use special care with aluminum trim. To avoid
damaging protective trim, never use auto or chrome
polish, steam or caustic soap to clean aluminum.
A coating of wax, rubbed to high polish, is
recommended for all bright metal parts.
Windshield and Wiper Blades
Clean the outside of the windshield with glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer fluid or a mild
detergent. Wash the windshield thoroughly when
cleaning the blades. Bugs, road grime, sap, and a
buildup of vehicle wash/wax treatments may cause
wiper streaking. Replace the wiper blades if they are
worn or damaged.
Wipers can be damaged by:
.Extreme dusty conditions
.Sand and salt
.Heat and sun
.Snow and ice, without proper removal

Aluminum or Chrome-Plated Wheels
and Trim
The 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:Chrome wheels and other chrome trim
may be damaged if the vehicle is not washed after
driving on roads that have been sprayed with
magnesium, calcium or sodium chloride. These
chlorides are used on roads for conditions such as
ice and dust. Always wash the vehicle's chrome
with soap and water after exposure.
Notice: Using strong soaps, chemicals, abrasive
polishes, cleaners, brushes, or cleaners that contain
acid on aluminum or chrome-plated wheels, could
damage the surface of the wheel(s). The repairs
would not be covered by the vehicle warranty. Use
only approved cleaners on aluminum or
chrome-plated wheels. The surface of these wheels is similar to the painted
surface of the vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes on
them because they 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 the vehicle 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: Driving the vehicle through an automatic
car wash that has silicone carbide tire cleaning
brushes, could damage the aluminum or
chrome-plated wheels. The repairs would not be
covered by the vehicle warranty. Never drive a
vehicle that has aluminum or chrome-plated wheels
through an automatic car wash that uses silicone
carbide tire cleaning brushes.

Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on the vehicle may damage the paint finish
and/or tires. When applying a tire dressing, always
wipe off any overspray from all painted surfaces on
the 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 vehicle
warranty.
Finish Damage
Any stone chips, fractures or deep scratches in the
finish 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 finish 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, floor pan,
and exhaust system even though they have corrosion
protection.
At least every spring, flush 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 flushed.
Your dealer or an underbody car washing system can
do this.
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, we 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 first.

Vehicle Identification
Vehicle Identification Number (VIN)
This legal identifier is in the front corner of the
instrument panel, on the driver side. It can be seen
through the windshield from outside. The VIN also
appears on the Vehicle Certification and Service Parts
labels and certificates of title and registration.
Engine Identification
The eighth character in the VIN is the engine code. This
code identifies the vehicle's engine, specifications, and
replacement parts. See“Engine Specifications”under
Capacities and Specifications
on page 6‑128for the
vehicle's engine code.
Service Parts Identification Label
This label, on the spare tire cover, has the following
information:
.Vehicle Identification Number (VIN)
.Model designation
.Paint information
.Production options and special equipment
Do not remove this label from the vehicle.
Electrical System
Add-On Electrical Equipment
Notice: Do not add anything electrical to the vehicle
unless you check with your dealer first. Some
electrical equipment can damage the vehicle and
the damage would not be covered by the vehicle's
warranty. Some add-on electrical equipment can
keep other components from working as they
should.
Add-on equipment can drain the vehicle battery, even if
the vehicle is not operating.
6-114

Black plate (115,1)Cadillac STS Owner Manual - 2011
The vehicle has an airbag system. Before attempting to
add anything electrical to the vehicle, seeServicing
Your Airbag-Equipped Vehicle
on page 2‑70and
Adding Equipment to Your Airbag-Equipped Vehicleon
page 2‑71.
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 the 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.
Power Windows and Other Power
Options
Circuit breakers in the fuse block protect the power
windows and other power accessories. When the
current load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is fixed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of fires 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.
Fuses of the same amperage can be temporarily
borrowed from another fuse location, if a fuse goes out.
Replace the fuse as soon as you can.

Black plate (117,1)Cadillac STS Owner Manual - 2011
The underhood fuse block is located in the front of the

vehicle. SeeEngine Compartment Overview
on
page 6‑13for 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.
Notice: Spilling liquid on any electrical component
on the vehicle may damage it. Always keep the
covers on any electrical component.
