service reset CADILLAC CTS V 2005 1.G Owners Manual

When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake doesn’t
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push, or the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-38.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed
for service.
Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That is
normal.
If the ABS warning light comes on and stays on, there
may be a problem with the anti-lock portion of the brake
system. If the red BRAKE light is not on, you still
have brakes, but you do not have anti-lock brakes. See
Brake System Warning Light on page 3-41.
If the light stays on, turn the ignition to OFF. If the light
comes on when you are driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on,
or comes on again while you are driving, your vehicle
needs service. If the regular brake system warning light
is not on, you still have brakes, but you do not have
anti-lock brakes. If the regular brake system warning
light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
Brake System Warning Light on page 3-41.

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 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.
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 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.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 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.
5-19

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 CTS Navigation System Owner
Supplement for how to reset the oil life indicator.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
lter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or
into streams or bodies of water. Instead, recycle it
by taking it to a place that collects used oil. If you have
a problem properly disposing of your used oil, ask
your dealer, a service station or a local recycling
center for help.

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 4-33, for an example of the tire and loading
information label and its location on your vehicle.
If your vehicle has run-at tires, the Tire Pressure
Monitor (TPM) system will need to have the sensors
reset after a tire rotation is performed. A special tool is
needed to reset the sensor identication codes. See
your dealer for service.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Specications on page 5-107.
{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 needed, to get
all the rust or dirt off. SeeChanging a Flat
Tire (CTS) on page 5-76.
