ECU CADILLAC STS V 2007 1.G Workshop Manual

{CAUTION:
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.
When replacing a pressure cap, make sure it is
hand-tight and fully seated.
Coolant Surge Tank Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
The coolant surge tank pressure cap must be fully
installed on the coolant surge tank. SeeEngine
Compartment Overview on page 373for more
information on location.
Engine Overheating
There are two engine hot messages that could be
displayed in the Driver Information Center (DIC).
SeeDIC Warnings and Messages on page 264for
more information.
If the engine is overheating, then you will nd a
coolant temperature gage and a coolant warning
light on the instrument panel. SeeEngine
Coolant Temperature Gage on page 251and
Engine Coolant Temperature Warning Light on
page 251for more information.

Tire Chains
{CAUTION:
If your vehicle has P255/45R17,
P255/45R18, P275/40R19, or 255/45ZR18
size tires, do not use tire chains, as there
is not enough clearance.
Tire chains used on a vehicle without the
proper amount of clearance can cause
damage to the brakes, suspension, or
other vehicle parts. The area damaged by
the tire chains could cause you to lose
control of your vehicle and you or others
may be injured in a crash.
Use another type of traction device only if
its manufacturer recommends it for use
on your vehicle and tire size combination
and road conditions. Follow that
manufacturer’s instructions.
CAUTION: (Continued)
CAUTION: (Continued)
To help avoid damage to your vehicle,
drive slowly, readjust, or remove the
device if it is contacting your vehicle, and
do not spin your vehicle’s wheels.
If you do nd traction devices that will t,
install them on the rear tires only.
Notice:If your vehicle has P235/50R17 95S
size tires, use tire chains only where legal and
only when you must. Use only SAE Class
S-type chains that are the proper size for your
tires. Install them on the rear tires and
tighten them as tightly as possible with the
ends securely fastened. Drive slowly and follow
the chain manufacturer’s instructions. If you
can hear the chains contacting your vehicle,
stop and retighten them. If the contact
continues, slow down until it stops. Driving
too fast or spinning the wheels with chains on
will damage your vehicle.

16. If the at tire was
able to inate to the
recommended
ination pressure,
remove the
maximum speed
label from the
sealant canister.
Place it in a highly visible location such as the
inside of the upper left corner of the
windshield or to the face of the radio/clock.
The maximum speed label reminds you
to drive cautiously and not to exceed 55 mph
(90 km/h) until you have the damaged tire
inspected and repaired.
{CAUTION:
Storing the tire inator kit or other
equipment in the passenger compartment
of the vehicle could cause injury. In a
sudden stop or collision, loose equipment
could strike someone. Store the tire
inator kit in the proper place.
17. Return the equipment to the proper storage
location in the trunk of your vehicle. You may
need to loosen the retention strap to wrap
it around the inator kit and foam container. To
do this, pull apart the strap and loosen the
strap at the quick release buckle. Then snap
the buckle together, pull the strap tight,
and secure the loose end of the strap by
mating the ends.

4. Push the air compressor inator hose onto the
tire valve stem and push the lever down to
secure in place.
5. Plug the air compressor accessory plug into
an accessory power outlet in the vehicle. See
Accessory Power Outlet(s) on page 228for
more information.
{CAUTION:
Idling the engine in a closed-in place or
with the climate control system off can
cause deadly carbon monoxide (CO). See
Engine Exhaust on page 125.
6. Start the vehicle. SeeStarting the Engine on
page 113for more information. The vehicle
must be running while using the air
compressor.
{CAUTION:
Inating something too much can make it
explode, and you or others could be
injured. Be sure to read the inator
instructions, and inate the tire to its
recommended pressure. Do not exceed
36 psi (248 kPa).
7. Move the inator kit switch to the I (on)
position.
8. Make sure there is a proper connection
between the tire valve stem and the air
compressor hose by looking at the air
pressure gage. If there is not a pressure
reading while the compressor is running, the
connection between the inator kit and
the tire is bad.
Check the attachment between the air
compressor hose and the tire valve stem.

{CAUTION:
A safety belt that is not properly routed
through the seat cushion or is twisted will
not provide the protection needed in a
crash. If the safety belt has not been
routed through the seat cushion at all, it
will not be there to work for the next
passenger. The person sitting in that
position could be badly injured. After
reinstalling the seat cushion, always
check to be sure that the safety belts are
properly routed and are not twisted.
1. Buckle the center passenger position safety
belt, then route the safety belts through the
proper slots in the seat cushion. Do not let the
safety belts get twisted.
2. Slide the rear of the cushion up and under the
seatback so the rear-locating guides hook into
the wire loops on the back frame.3. With the seat cushion lowered, push rearward
and then press down on the seat cushion until
the spring locks on both ends engage.
4. Check to make sure the safety belts are
properly routed and that no portion of any
safety belt is trapped under the seat.
Also make sure the seat cushion is secured.
Rear Underseat Fuse Block
There is a fuse block located under the rear seat
on the driver’s side and passenger’s side of
the vehicle. The rear seat cushion must be
removed to access the fuse blocks. See
“Removing the Rear Seat Cushion” listed
