reset CADILLAC CTS 2007 1.G Owner's Guide

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. Substitute
oil not meeting GM Standard GM4718M should
not be used for an oil change.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
standards are all you need for good performance
and engine protection.
Engine Oil Life System
When to Change Engine Oil
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 changewill be indicated can vary considerably. For the oil
life system to work properly, you must reset the
system every time the oil is changed.
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
Driver Information Center (DIC) will come on.
Change your oil as soon as possible within the next
600 miles (1 000 km). 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 Engine Oil Life
System and the Oil Life Indicator
The Engine 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.Navigation System
If you have the navigation system, see “Vehicle
Customization” in the Navigation System Manual
for how to reset the oil life indicator.

Automatic Transmission Fluid
It is not necessary to check the transmission uid
level. A transmission uid leak is the only
reason for uid loss. If a leak occurs, take your
vehicle to your GM dealer service department and
have it repaired as soon as possible.
Change the uid and lter at the intervals listed in
Additional Required Services on page 465, and
be sure to use the transmission uid listed in
Recommended Fluids and Lubricants on page 473.
Notice:Use of the incorrect automatic
transmission uid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission uid listed inRecommended
Fluids and Lubricants on page 473.
How to Reset the Change Transmission
Fluid Message and the Transmission

If your vehicle has a navigation system, see your
Navigation System Manual for instructions on
how to acknowledge the Change Trans Fluid
message and reset the transmission uid
life indicator.
Manual Transmission Fluid
When to Check Manual Transmission
Fluid
It is not necessary to check the manual
transmission uid level. A transmission uid leak is
the only reason for uid loss. If a leak occurs, take
the vehicle to your GM dealer service department
and have it repaired as soon as possible.
How to Check Manual Transmission
Fluid
Because this operation can be difficult, you may
choose to have this done at your GM dealer
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 parts 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.

Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory
and should need no further adjustment.
However, if the vehicle is damaged in an accident,
the headlamp aim may be affected and adjustment
may be necessary.
If oncoming vehicles ash their high beams at
you, this may also mean the vertical aim needs to
be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need to
be re-aimed. It is possible however, to re-aim the
headlamps as described in the following procedure.The vehicle should be properly prepared as follows:The vehicle should be placed so the headlamps
are 25 ft. (7.6 m) from a light colored wall.
The vehicle must have all four tires on a level
surface which is level all the way to the wall.
The vehicle should be placed so it is
perpendicular to the wall.
The vehicle should not have any snow, ice, or
mud on it.
The vehicle should be fully assembled and all
other work stopped while headlamp aiming is
being performed.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs
(75 kg) sitting on the driver’s seat.
Tires should be properly inated.
The spare tire is in its original location in the
vehicle.

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.
407

When rotating your vehicle’s tires, always use the
correct rotation pattern shown here.
If your vehicle has a compact spare tire, do not
include it in the tire rotation.
After the tires have been rotated, adjust the front
and rear ination pressures as shown on the Tire
and Loading Information label. SeeLoading Your
Vehicle on page 321, for an example of the tire and
loading information label and its location on your
vehicle.
If your vehicle has the Tire Pressure Monitor
System (TPMS) the TPMS sensors will need to be
reset and matched to the tire/wheel position. A
special TPMS diagnostic tool is used to reset the
sensor identication codes. See your dealer for
service.Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 457.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after 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 needed, to get all the rust or dirt
off. SeeChanging a Flat Tire (CTS Only)
on page 424.
