Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9‑10.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that thetire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
on page 10‑68.
Tire Sealant and
Compressor Kit
This vehicle may come with a spare
tire and tire changing equipment or
a tire sealant and compressor kit.
The kit can be used to temporarily
seal small punctures in the tread
area of the tire. See Tire Sealant
and Compressor Kit on page 10‑82.
If the vehicle came with a spare tire
and tire changing equipment, see If
a Tire Goes Flat on page 10‑80.
Engine Oil Life System

certification mark indicates that the
oil has been approved to the dexos1
specification.
Notice:Failure to use the
recommended engine oil or
equivalent can result in engine
damage not covered by the
vehicle warranty. Check with your
dealer or service provider on
whether the oil is approved to the
dexos1 specification.
Viscosity Grade
SAE 5W-30 is the best viscosity
grade for the vehicle. Do not use
other viscosity grade oils such as
SAE 10W-30, 10W-40, or 20W-50.
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below −29°C
(−20°F), an SAE 0W-30 oil may be used. An oil of this viscosity grade
will provide easier cold starting for
the engine at extremely low
temperatures. When selecting an oil
of the appropriate viscosity grade,
always select an oil of the correct
specification. See
“Specification”
earlier in this section.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the dexos
specification and displaying the
dexos certification mark are all that
is needed for good performance and
engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
What to Do with Used Oil
Used engine oil contains certain
elements that can 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 filter before disposal. Never
dispose of oil by putting it in the
trash or pouring it on the ground,
into sewers, or into streams or
bodies of water. Recycle it by taking
it to a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on a combination of factors which
include engine revolutions, engine
temperature, and miles driven.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For

Black plate (12,1)Cadillac CTS/CTS-V Owner Manual - 2013 - crc2 - 8/22/12
10-12 Vehicle Care
the oil life system to work properly,
the system must be reset every time
the oil is changed.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on. See
Engine Oil Messages on page 5‑35.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and at this time the system must be
reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Using the DIC MENU button,
display OIL LIFE REMAINING
on the DIC. See Driver
Information Center (DIC) on
page 5‑27 andEngine Oil
Messages on page 5‑35.
2. Press the Set/Reset button and hold for two seconds to clear the
CHANGE ENGINE OIL SOON
message and reset the oil life
at 100%.
Be careful not to reset the oil life
display accidentally at any time
other than after the oil is changed. It cannot be reset
accurately until the next oil
change.
The oil life system can also be reset
as follows:
1. Turn the ignition on with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
If the CHANGE ENGINE OIL
SOON message is not on, the
system is reset.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.

Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as soon
as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, it should be
done at the dealer. Contact your
dealer for additional information or
refer to the procedure in the service
manual. To purchase a service
manual, seeService Publications
Ordering Information on page 13‑16. Change the fluid and filter at the
intervals listed in
Maintenance
Schedule on page 11‑3, and be sure
to use the fluid listed in
Recommended Fluids and
Lubricants on page 11‑13.
Manual Transmission
Fluid
It is not necessary to check the
manual transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to a dealer
for service. Have it repaired as soon
as possible. You may also have the
fluid level checked by your dealer
when the oil is changed. See
Recommended Fluids and
Lubricants on page 11‑13 for the
proper fluid to use.
Hydraulic Clutch
It is not necessary to regularly
check clutch fluid unless you
suspect there is a leak in the
system. Adding fluid will not correct a leak. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
When to Check and What
to Use
The hydraulic clutch fluid reservoir
cap has this symbol on it. See
Engine Compartment Overview on
page 10‑5
for reservoir location.
Refer to the Maintenance Schedule

The engine air cleaner/filter is in the
engine compartment on the driver
side of the vehicle, near the front.
SeeEngine Compartment Overview
on page 10‑5.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the
scheduled maintenance intervals
and replace it at the first oil change
after each 80 000 km (50,000 mile)
interval. See Maintenance Schedule
on page 11‑3. If you are driving in
dusty/dirty conditions, inspect the
filter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter to release
loose dust and dirt. If the filter
remains covered with dirt, a new
filter is required.
To inspect or replace the engine air
cleaner/filter:
1. Turn the ignition off.
2. Remove the side cover by pulling up on the front of the
cover.
