Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and
find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right in front of you. These
problems can be avoided by braking—if you can stop
in time. But sometimes you cannot stop in time because
there is no room. That is the time for evasive
action —steering around the problem.
The vehicle can perform very well in emergencies like
these. First apply the brakes. See Braking
on
page 5‑4. It is better to remove as much speed as
possible from a collision. Then steer around the
problem, to the left or right depending on the space
available.
An emergency like this requires close attention and a
quick decision. If holding the steering wheel at the
recommended 9 and 3 o'clock positions, it can be
turned a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving
at all times and wear safety belts properly.

Filling the Tank
{WARNING:
Fuel vapor burns violently and a fuel fire can
cause bad injuries. To help avoid injuries to you
and others, read and follow all the instructions on
the fuel pump island. Turn off the engine when
refueling. Do not smoke near fuel or when
refueling the vehicle. Do not use cellular phones.
Keep sparks, flames, and smoking materials away
from fuel. Do not leave the fuel pump unattended
when refueling the vehicle. This is against the law
in some places. Do not re-enter the vehicle while
pumping fuel. Keep children away from the fuel
pump; never let children pump fuel.
The tethered fuel cap
is located behind a
hinged fuel door on the
passenger side of the
vehicle.
To open the fuel door, push the rearward center edge in
and release and it will open.
To remove the fuel cap, turn it slowly counterclockwise.
The fuel cap has a spring in it; if the cap is released too
soon, it will spring back to the right.

Black plate (10,1)Cadillac STS Owner Manual - 2011
While refueling, hang the tethered fuel cap from the
hook on the fuel door.
{WARNING:
Fuel can spray out on you if you open the fuel cap
too quickly. If you spill fuel and then something
ignites it, you could be badly burned. This spray
can happen if the tank is nearly full, and is more
likely in hot weather. Open the fuel cap slowly and
wait for any hiss noise to stop. Then unscrew the
cap all the way.
Be careful not to spill fuel. Do not top off or overfill the
tank, and wait a few seconds after you have finished
pumping before removing the nozzle. Clean fuel from
painted surfaces as soon as possible. See Washing
Your Vehicle on page 6‑109. When replacing the fuel cap, turn it clockwise until it
clicks. Make sure the cap is fully installed. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. This would allow
fuel to evaporate into the atmosphere. See
Malfunction
Indicator Lamp on page 4‑62.
The CHECK GAS CAP message will appear on the
Driver Information Center (DIC) display if the fuel cap is
not reinstalled properly. See DIC Warnings and
Messages
on page 4‑76for more information.

How to Add Coolant to the Surge Tank
{WARNING:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot enough.
Do not spill coolant on a hot engine.
{WARNING:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and if you turn the coolant surge
tank pressure cap—even a little —they can come
out at high speed. Never turn the cap when the
cooling system, including the coolant surge tank
pressure cap, is hot. Wait for the cooling system
and coolant surge tank pressure cap to cool if you
ever have to turn the pressure cap.
{WARNING:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
If no coolant is visible in the surge tank, add coolant as
follows: 1. Remove the coolant surge tank pressure cap when the cooling system, including the coolant surge
tank pressure cap and upper radiator hose, is
no longer hot. Turn the pressure cap slowly
counterclockwise about one-quarter of a turn.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.

Using the Tire Sealant and Compressor
Kit to Temporarily Seal and Inflate a
Punctured Tire
When using the tire sealant and compressor kit
during cold temperatures, warm the kit in a heated
environment for five minutes. This will help to inflate
the tire faster.If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on the hazard
warning flashers. See
Hazard Warning Flashers
on
page 4‑3.
See If a Tire Goes Flat
on page 6‑74for other
important safety warnings.
Do not remove any objects that have penetrated
the tire.
1. Remove the tire sealant and compressor kit from its storage location. See Tire Sealant and
Compressor Kit Storage on page 6‑94.
Make sure the on/off button (D) is in the off (O)
position.
2. Unwrap the sealant/air hose (G) and the power plug (C).
3. Place the kit on the ground. Make sure the tire valve stem is positioned close to
the ground so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it counterclockwise.
5. Attach the sealant/air hose (G) onto the tire valve stem. Turn it clockwise until it is tight.
6-79

11. Unplug the power plug (C) from the accessorypower outlet in the vehicle.
12. Turn the sealant/air hose (G) counterclockwise to remove it from the tire valve stem.
13. Replace the tire valve stem cap.
14. Replace the sealant/air hose (G), and the power plug (C) back in their original location.
15. If the flat tire was ableto inflate to the
recommended inflation
pressure, remove the
maximum speed label
from the sealant
canister (B) and place
it in a highly visible
location.
Do not exceed the speed on this label until the
damaged tire is repaired or replaced.
16. Return the equipment to its original storage location in the vehicle.
17. Immediately drive the vehicle 8 km (5 miles) to distribute the sealant in the tire. 18. Stop at a safe location and check the tire pressure.
Refer to Steps 1 through 11 under “Using the Tire
Sealant and Compressor Kit without Sealant to
Inflate a Tire (Not Punctured).”
If the tire pressure has fallen more than 68 kPa
(10 psi) below the recommended inflation
pressure, stop driving the vehicle. The tire is too
severely damaged and the tire sealant cannot seal
the tire. See Roadside Service on page 8‑8.
If the tire pressure has not dropped more than
68 kPa (10 psi) from the recommended inflation
pressure, inflate the tire to the recommended
inflation pressure.
19. Wipe off any sealant from the wheel, tire or vehicle.
20. Dispose of the used sealant canister (B) and sealant/air hose (G) assembly at a local dealer or
in accordance with local state codes and practices.
21. Replace it with a new canister available from your dealer.
22. After temporarily sealing a tire using the tire sealant and compressor kit, take the vehicle to an
authorized dealer within a 161 km (100 miles) of
driving to have the tire repaired or replaced.
