2011 CADILLAC STS engine oil

Black plate (36,1)Cadillac STS Owner Manual - 2011
What to Add
DOT 3 brake fluid is recommended. DOT 4 brake fluid
is also compatible with the vehicle's brake system parts.
However, if DOT 4 fluid is used, it is recommended that
the brake hydraulic system be flushed and refilled with
new DOT 4 fluid at a regular maintenance service every
two years. SeeScheduled Maintenance
on page 7‑3.
Use new brake fluid from a sealed container only. See
Recommended Fluids and Lubricants on page 7‑9.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This helps keep dirt
from entering the reservoir.
{WARNING:
With the wrong kind of fluid in the brake hydraulic
system, the brakes might not work well. This could
cause a crash. Always use the proper brake fluid. Notice:
.Using the wrong fluid can badly damage
brake hydraulic system parts. For example,
just a few drops of mineral-based oil, such
as engine oil, in the brake hydraulic system
can damage brake hydraulic system parts so
badly that they will have to be replaced. Do
not let someone put in the wrong kind of
fluid.
.If brake fluid is spilled on the vehicle's
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on the vehicle. If you do, wash it off
immediately. See
Washing Your Vehicle
on
page 6‑109
.
Brake Wear
This vehicle has disc brakes. Disc brake pads have
built-in wear indicators that make a high-pitched
warning sound when the brake pads are worn and new
pads are needed. The sound can come and go or be
heard all the time the vehicle is moving, except when
applying the brake pedal firmly.

The underhood fuse block is located in the front of the
engine compartment on the passenger side 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.

At your dealer, you can be certain that you will receive
the highest level of service available. Your dealer has
specially trained service technicians, uses genuine
replacement parts, as well as, up‐to‐date tools and
equipment to ensure fast and accurate diagnostics.
The proper replacement parts, fluids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 7‑9andMaintenance Replacement Partson
page 7‑11. We recommend the use of genuine parts
from your dealer.
Rotation of New Tires
Tire rotation is not recommended if the vehicle has
different size tires on the front and rear wheels. If tire
rotation is recommended for the vehicle, to maintain
ride, handling, and performance of the vehicle, it is
important that the first rotation service for new tires
be performed. Tires should be rotated every
12 000 km/7,500 miles. See Tire Inspection and
Rotation on page 6‑65.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oilon
page 6‑16. An Emission Control Service.
When the CHANGE ENGINE OIL SOON message
displays, service is required for the vehicle as soon as
possible, within the next 1 000 km/600 miles. If driving
under the best conditions, the engine oil life system
might not indicate the need for vehicle service for more
than a year. The engine oil and filter must be changed
at least once a year and the oil life system must be
reset. Your dealer has trained service technicians who
will perform this work and reset the system. If the
engine oil life system is reset accidentally, service the
vehicle within 5 000 km/3,000 miles since the last
service. Reset the oil life system whenever the oil is
changed. See Engine Oil Life System on page 6‑20.
When the Change Engine Oil Soon message displays,
certain services, checks, and inspections are required.
