2011 CADILLAC STS check engine

Black plate (39,1)Cadillac STS Owner Manual - 2011
Notice:Ignoring these steps could result in costly
damage to the vehicle that would not be covered by
the warranty.
Trying to start the vehicle by pushing or pulling it
will not work, and it could damage the vehicle.
1. Check the other vehicle. It must have a 12-volt battery with a negative ground system.
Notice: If the other vehicle's system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not
touching each other. If they are, it could cause a
ground connection you do not want. You would not
be able to start your vehicle and the bad grounding
could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in P (Park) or a manual transmission
in NEUTRAL before setting the parking brake. Notice:
If you leave the radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered by
the warranty. Always turn off the radio and other
accessories when jump starting the vehicle.
3. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the
cigarette lighter or the accessory power outlets.
Turn off the radio and all lamps that are not
needed. This will avoid sparks and help save both
batteries. And it could save the radio!
4. Open the hoods and locate the positive (+) and negative (−) terminal locations or the remote
positive (+) and remote negative (−) terminals of
the other vehicle. Then locate the remote
positive (+) location on your vehicle. See Engine
Compartment Overview
on page 6‑13for more
information on locations the terminals.

{WARNING:
Using an open flame near a battery can cause
battery gas to explode. People have been hurt
doing this, and some have been blinded. Use a
flashlight if you need more light.
Be sure the battery has enough water. You do not
need to add water to the battery installed in your
new vehicle. But if a battery has filler caps, be
sure the right amount of fluid is there. If it is low,
add water to take care of that first. If you do not,
explosive gas could be present.
Battery fluid contains acid that can burn you. Do
not get it on you. If you accidentally get it in your
eyes or on your skin, flush the place with water
and get medical help immediately.
{WARNING:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
5. Check that the jumper cables do not have loose or missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative (−) will go to a
heavy, unpainted metal engine part or to a remote
negative (−) terminal if the vehicle has one.
Do not connect positive (+) to negative (−) or you
will get a short that would damage the battery and
maybe other parts too. And do not connect the
negative (−) cable to the negative (−) terminal on
the dead battery because this can cause sparks.

Notice:If the jumper cables are connected or
removed in the wrong order, electrical shorting may
occur and damage the vehicle. The repairs would
not be covered by the vehicle warranty. Always
connect and remove the jumper cables in the
correct order, making sure that the cables do not
touch each other or other metal.
Jumper Cable Removal
A. Heavy, Unpainted Metal Engine Part or Remote Negative (−) Terminal
B. Good Battery or Remote Positive (+) and Remote Negative (−) Terminals
C. Dead Battery or Remote Positive (+) Terminal To disconnect the jumper cables from both vehicles, do
the following:
1. Disconnect the black negative (−) cable from the vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the vehicle with the good battery.
4. Disconnect the red positive (+) cable from the other vehicle.
All-Wheel Drive
All of the lubricant checks in this section apply to your
vehicle. If you have an all-wheel-drive vehicle, there is
an additional system that need lubrication.
Transfer Case
When to Check Lubricant
It is not necessary to regularly check the transfer case
fluid unless you suspect there is a leak or you hear an
unusual noise. A fluid loss could indicate a problem.
Have it inspected and repaired.

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.
