engine CADILLAC CTS 2007 1.G Owners Manual

What to Add
When you do need brake uid, DOT-3 brake uid
is recommended for use. DOT-4 brake uid is
also compatible with your vehicle’s brake system
parts. However, if you choose to use DOT-4
uid, it is recommended that you ush your brake
hydraulic system and rell it with new DOT-4
uid at a regular maintenance service every
two years. SeeAdditional Required Services on
page 465. Use new brake uid from a sealed
container only. SeeRecommended Fluids
and Lubricants on page 473.
Always clean the brake uid reservoir cap and the
area around the cap before removing it. This
will help keep dirt from entering the reservoir.{CAUTION:
With the wrong kind of uid in the brake
system, the brakes may not work well.
This could cause a crash. Always use the
proper brake uid.
Notice:
Using the wrong uid can badly damage
brake system parts. For example, just a
few drops of mineral-based oil, such
as engine oil, in the brake system can
damage brake system parts so badly that
they will have to be replaced. Do not
let someone put in the wrong kind of uid.
If you spill brake uid on your vehicle’s
painted surfaces, the paint nish can
be damaged. Be careful not to spill brake
uid on your vehicle. If you do, wash it
off immediately. SeeWashing Your Vehicle
on page 439.

Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. We recommend an ACDelco
®
replacement battery. SeeEngine Compartment
Overview on page 342for battery location.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm. Wash
hands after handling.
{CAUTION:
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful. SeeJump
Starting on page 376for tips on working
around a battery without getting hurt.
After a power loss, such as disconnecting the
battery or removing the maxi fuses in the power
distribution fuse block, the following steps must be
performed to calibrate the electronic throttle control.
If this is not done, the engine will not run properly.
1. Turn the ignition key to ON. Do not start the
engine.
2. Leave the ignition in ON for at least
three minutes so that the electronic throttle
control will cycle and re-learn its home
position.
3. Turn the ignition to OFF.
4. Start and run the engine for at least
30 seconds.
375

Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your 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 of the
other vehicle, as well as the positive (+)
terminal location on your vehicle’s battery.
SeeEngine Compartment Overview on
page 342for more information on the location
of the battery.
377

Your vehicle has a remote negative (−) ground
location, as shown in the illustration. It is
located between the battery and the
underhood fuse block. You should always use
this remote ground location, instead of the
terminal on the battery.Notice:If you connect a negative cable to the
ECM engine control module, ECM mounting
bracket, or any cables that attach to the
ECM bracket, you may damage the ECM.
Always attach the negative cable to your
vehicle’s remote negative ground location,
instead of the ECM, ECM bracket, or any cables
attached to the ECM bracket.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
378

{CAUTION:
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a ashlight 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 ller caps, be sure the
right amount of uid is there. If it is low,
add water to take care of that rst. If you
do not, explosive gas could be present.
Battery uid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.
{CAUTION:
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.
379

6. Connect the red positive (+) cable to the
positive (+) terminal of the dead battery.
Use a remote positive (+) terminal if
the vehicle has one.
7. Do not let the other end touch metal. Connect
it to the positive (+) terminal of the good
battery. Use a remote positive (+) terminal if
the vehicle has one.
8. Now connect the black negative (−) cable to
the negative terminal of the good battery. Use
a remote negative (−) terminal if the vehicle
has one.Do not let the other end touch anything until the
next step. The other end of the negative (−)
cable does not go to the dead battery. It goes to
a heavy, unpainted metal engine part or to a
remote negative (−) terminal on the vehicle with
the dead battery.
9. Connect the other end of the negative (−) cable
at least 18 inches (45 cm) away from the dead
battery, but not near engine parts that move.
The electrical connection is just as good there,
and the chance of sparks getting back to the
battery is much less.
Use a remote negative (−) terminal if the
vehicle has one. Your vehicle’s remote
negative (−) ground location is for this
purpose.
10. Now start the vehicle with the good battery
and run the engine for a while.
11. Try to start the vehicle that had the dead
battery. If it will not start after a few tries, it
probably needs service.
380

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 your 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.
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 (+) TerminalTo 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.

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear or cracking. SeeOwner Checks and Services
on page 469.
It is a good idea to clean or replace the wiper
blade assembly on a regular basis or when worn.
For proper windshield wiper blade length and
type, seeNormal Maintenance Replacement Parts
on page 475.
To replace the wiper blade assembly, do the
following:
1. Turn the ignition to ON with the engine off.
2. Turn on the windshield wipers and turn them
off again when the wipers are in the out-wipe
position. The driver’s side blade will be
straight up and down on the windshield.3. Pull the windshield wiper assembly away from
the windshield.
4. Lift the wiper blade assembly up so it is in
a T-shaped position. You should be able to
see a tab.

(B) Tire Ply Material:The type of cord and
number of plies in the sidewall and under the
tread.
(C) Tire Identication Number (TIN):The letters
and numbers following the DOT (Department of
Transportation) code is the Tire Identication
Number (TIN). The TIN shows the manufacturer
and plant code, tire size, and date the tire
was manufactured. The TIN is molded onto both
sides of the tire, although only one side may have
the date of manufacture.
(D) Maximum Cold Ination Load Limit:
Maximum load that can be carried and the
maximum pressure needed to support that load.
(E) Tire Ination:The temporary use tire or
compact spare tire should be inated to 60 psi
(420 kPa). For more information on tire pressure
and ination seeInation - Tire Pressure on
page 402.
(F) Tire Size:A combination of letters and
numbers dene a tire’s width, height, aspect ratio,
construction type, and service description. The
letter T as the rst character in the tire size means
the tire is for temporary use only.(G) TPC Spec (Tire Performance Criteria
Specication):Original equipment tires designed
to GM’s specic tire performance criteria have
a TPC specication code molded onto the sidewall.
GM’s TPC specications meet or exceed all
federal safety guidelines.
Tire Size
The following illustration shows an example of a
typical passenger vehicle tire size.
(A) Passenger (P-Metric) Tire:The United
States version of a metric tire sizing system.
The letter P as the rst character in the tire size
means a passenger vehicle tire engineered
to standards set by the U.S. Tire and Rim
Association.

Your vehicle’s TPMS can alert you about a low
tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 409andTires on page 392.
Notice:Do not use a tire sealant if your vehicle
has Tire Pressure Monitors. The liquid sealant
can damage the tire pressure monitor sensors.
Resetting the TPMS Identication
Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors or rotate the tires, the
identication codes will need to be matched to the
new tire and wheel position. The sensors are
matched to the tire and wheel positions in
the following order: driver’s side front tire,
passenger’s side front tire, passenger’s side rear
tire, and driver’s side rear tire using a TPMS
diagnostic tool. See your GM dealer for service.
The TPMS sensors may also be matched to each
tire and wheel position by increasing or
decreasing the tire’s air pressure. When increasing
tire pressure do not exceed the maximum
ination pressure indicated on the tire’s sidewall.You will have two minutes to match the rst tire
and wheel position, and ve minutes overall
to match all four tire and wheel positions. If it takes
longer than two minutes, to match the rst tire
and wheel, or more than ve minutes to match all
four tire and wheel positions the matching
process stops and you will need to start over.
The TPM matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON with the
engine off.
3. Using the Remote Keyless Entry (RKE)
transmitter, lock and unlock the vehicle’s
doors.
4. Press the lock and unlock buttons, at the
same time, on the RKE transmitter. A single
horn chirp will sound, indicating that the
TPMS system is ready, and the sensor
matching process can begin.
5. Start with the driver’s side front tire.
