2004 CADILLAC CTS change time

Do not get too close to the vehicle you want to
pass while you are awaiting an opportunity. For one
thing, following too closely reduces your area of
vision, especially if you are following a larger
vehicle. Also, you will not have adequate space if
the vehicle ahead suddenly slows or stops.
Keep back a reasonable distance.
When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and
do not get too close. Time your move so you will be
increasing speed as the time comes to move into
the other lane. If the way is clear to pass, you
will have a running start that more than makes up
for the distance you would lose by dropping
back. And if something happens to cause you
to cancel your pass, you need only slow
down and drop back again and wait for
another opportunity.
If other vehicles are lined up to pass a slow vehicle,
wait your turn. But take care that someone is not
trying to pass you as you pull out to pass the slow
vehicle. Remember to glance over your shoulder
and check the blind spot.
Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far
enough ahead of the passed vehicle to see its front
in your inside mirror, activate your right lane
change signal and move back into the right lane.
Remember that your right outside mirror is convex.
The vehicle you just passed may seem to be
farther away from you than it really is.
Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.
Do not overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not ashing,
it may be slowing down or starting to turn.
If you are being passed, make it easy for the
following driver to get ahead of you. Perhaps
you can ease a little to the right.

SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle. However, you can use SAE 10W-30
if it is going to be 0°F (–18°C) or above.
These numbers on an oil container show its
viscosity, or thickness. Do not use other viscosity oils
such as SAE 20W-50.
Oils meeting these
requirements should also
have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certied by the American
Petroleum Institute (API).
You should look for this on the oil container, and use
onlythose oils that are identied as meeting GM
Standard GM4718M and have the starburst symbol on
the front of the oil container.
Your vehicle’s engine is lled at the factory with a
Mobil 1
®synthetic oil, which meets all requirements
for your vehicle.Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M may
not be available. You can add substitute oil designated
SAE 5W-30 with the starburst symbol at all temperatures.
If temperatures are above 0°F (–18°C), you may
substitute SAE 10W-30 with the starburst symbol.
Substitute oil not meeting GM Standard GM4718M
should not be used for an oil change.
Engine Oil Additives
Do not add anything to your oil. The recommended oils
with the starburst symbol that meet GM Standard
GM4718M are all you will need for good performance
and engine protection.
When to Change Engine Oil
(GM Oil Life System)
Your vehicle has a computer system that lets you know
when to change the engine oil and lter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage at which an oil change will be indicated
can vary considerably. For the oil life system to
work properly, you must reset the system every time
the oil is changed.
5-21

When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A Change Engine Oil message in the DIC
will come on. Change your oil as soon as possible within
the next two times you stop for fuel. It is possible that,
if you are driving under the best conditions, the oil
life system may not indicate that an oil change is
necessary for over a year. However, your engine oil and
lter must be changed at least once a year and at
this time the system must be reset. Your dealer has
GM-trained service people who will perform this
work using genuine GM parts and reset the system. It is
also important to check your oil regularly and keep it
at the proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.
How to Reset the Change Engine Oil
Message and the Oil Life Indicator
The GM Oil Life System calculates when to change
your engine oil and lter based on vehicle use.
Anytime your oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
Change Engine Oil Message in the DIC being turned on,
reset the system.After the oil has been changed, the Change Engine Oil
message and the oil life indicator must be reset.
To reset the message and indicator, use one of the
following procedures:
Base Audio System
Press the CLR button located to the right of the DIC
display to acknowledge the Change Engine Oil
message. This will clear the message from the display
and reset it.
To reset the oil life indicator, use the following steps:
1. Press the up or down arrow on the INFO button
located to the right of the DIC display to access
the DIC menu.
2. Once XXX% ENGINE OIL LIFE menu item is
highlighted, press and hold the CLR button.
The percentage will return to 100, and the oil life
indicator will be reset. Repeat the steps if the
percentage does not return to 100.
3. Turn the key to OFF.
If the Change Engine Oil message comes back on
when you start your vehicle, the engine oil life system
has not reset. Repeat the procedure.

Manual Transmission Fluid
When to Check
A good time to have your manual transmission uid
level checked is when the engine oil is changed.
However, the uid in your manual transmission does not
require changing.
How to Check
Because this operation can be difficult, you may
choose to have this done at your Cadillac dealership
service department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading.
Notice:Too much or too little uid can damage
your transmission. Too much can mean that some
of the uid could come out and fall on hot engine
part or exhaust system parts, starting a re.
Too little uid could cause the transmission to
overheat. Be sure to get an accurate reading if you
check your transmission uid.Check the uid level only when your engine is off, the
vehicle is parked on a level place and the transmission
is cool enough for you to rest your ngers on the
transmission case.
To check the uid level, do the following:
1. Remove the ller plug.
2. Check that the lubricant level is up to the bottom of
the ller plug hole.
3. If the uid level is good, install the plug and be sure
it is fully seated. If the uid level is low, add more
uid as described in the next steps.
How to Add Fluid
Here is how to add uid. SeeRecommended Fluids and
Lubricants on page 6-13to determine which type of
uid to use.
1. Remove the ller plug.
2. Add uid at the ller plug hole. Add only enough
uid to bring the uid level up to the bottom of the
ller plug hole.
3. Install the ller plug. Be sure the plug is
fully seated.

For example, if someone puts in brake linings that are
wrong for your vehicle, the balance between your
front and rear brakes can change — for the worse.
The braking performance you have come to expect can
change in many other ways if someone puts in the
wrong replacement brake parts.
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 5-12for 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 5-46
for 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.
Also, for your audio system, seeTheft-Deterrent Feature
on page 3-124.

The Tire and Loading Information label (tire information
placard) is attached, to either, the center pillar near the
driver’s door latch post or on the rear edge of the driver’s
side rear passenger door. The label shows the size of
your vehicle’s original tires and the correct ination
pressure for your vehicle’s tires when they are cold.
SeeInation - Tire Pressure on page 5-67andLoading
Your Vehicle on page 4-34for additional information.
Your vehicle’s TPM system can alert you about a low tire
pressure condition but it does not replace normal tire
maintenance. SeeTire Inspection and Rotation on
page 5-72andTires on page 5-58.
Each TPM sensor has a unique identication code that
is matched to one of the four tire positions on your
vehicle. Any time you rotate your vehicle’s tires
or replace one or more TPM sensors, the identication
codes will need to be matched to the new tire and
wheel position. The TPM matching process is performed
in a specic sequence and time limit. See your dealer
for service.Notice:Do not use a tire sealant if your vehicle
is equipped with Tire Pressure Monitors.
The liquid sealant can damage the tire pressure
monitor sensors.
The TPM system operates on a radio frequency subject
to Federal Communications Commission (FCC) Rules
and with Industry and Science Canada.
This device complies with Part 15 of the FCC Rules
and with RSS-210 of Industry and Science Canada.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.

Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Specications on page 5-111.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to,
to get all the rust or dirt off. SeeChanging a
Flat Tire on page 5-81.
When It Is Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of
tread remaining.
You need a new tire if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut or snagged
deep enough to show cord or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or
location of the damage.

9. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if you need to,
to get all the rust or dirt off.
{CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.
10. Place the compact
spare tire on the
wheel-mounting
surface.
