1-22 In Brief
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warning light alerts you
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. SeeVehicle Load
Limits
on page 9‑11. The warning
light will remain on until the tire
pressure is corrected.
During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. This may be an early indicator that the tire pressures are
getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal
monthly tire maintenance. It is the
driver
’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10‑76.
Tire Sealant and
Compressor Kit
This vehicle may come with a jack
and spare tire or a tire sealant and
compressor kit. The kit can be used
to seal small punctures in the tread
area of the tire.
SeeTire Sealant and Compressor
Kit
on page 10‑92for complete
operating information.
If the vehicle came with a jack and
spare tire, see If a Tire Goes Flat
on
page 10‑90.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the “Change Engine
Oil Soon” message when it is time
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System
1. Turn the ignition to ON/RUN with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
See Engine Oil Life System
on
page 10‑14.

5-20 Instruments and Controls
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
the vehicle's fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
vehicle warranty.
Notice: Modifications made to the
engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of the
original tires with other than
those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this light
to come on. Modifications to
these systems could lead to costly repairs not covered by the
vehicle warranty. This could also
result in a failure to pass a
required Emission Inspection/
Maintenance test. See
Accessories and Modifications
on
page 10‑4.
This light comes on during a
malfunction in one of two ways:
Light Flashing: A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
To prevent more serious damage to
the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the
amount of cargo being hauled as
soon as it is possible. If the light continues to flash, when
it is safe to do so, stop the vehicle.
Find a safe place to park the
vehicle. Turn the vehicle off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer for service as soon as
possible.
Light On Steady:
An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.

Engine Coolant
Temperature Warning
Light
The engine coolant temperature
warning light comes on briefly when
the engine is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally, the
indicator light then goes off.
If the light comes on and stays on
while driving, the vehicle may have
a problem with the cooling system.
Stop the vehicle and turn off the
engine to avoid damage to the
engine. A warning chime sounds
when this light is on.
SeeEngine Overheating
on
page 10‑24for more information.
Tire Pressure Light
For vehicles with a Tire Pressure
Monitor System, this light comes on
briefly when the engine is started.
It provides information about tire
pressures and the Tire Pressure
Monitor System.
When the Light is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A tire pressure message can
accompany the light. See Tire
Messages
on page 5‑43for more
information. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the Tire
and Loading Information Label. See
Tire Pressure
on page 10‑74for
more information. When the Light Flashes First and
Then is On Steady
This indicates that there may be a
problem with the Tire Pressure
Monitor System. The light flashes
for about a minute and stays on
steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.
See
Tire Pressure Monitor
Operation
on page 10‑77for more
information.

the Tire Pressure Monitor System
(TPMS) is not working properly. The
tire pressure light also flashes and
then remains on during the same
ignition cycle. See Tire Pressure
Light
on page 5‑25. Several
conditions may cause this message
to appear. See Tire Pressure
Monitor Operation
on page 10‑77for
more information. If the warning
comes on and stays on, there may
be a problem with the TPMS. See
your dealer.
Tire Learning Active
This message displays when the
Tire Pressure Monitor System
(TPMS) is re-learning the tire
positions on the vehicle. The tire
positions must be re-learned after
rotating the tires or after replacing a
tire or sensor. See Tire Rotation
on
page 10‑81, Tire Pressure Monitor
Systemon page 10‑76, and Tire
Pressureon page 10‑74for more
information.
Tire Low Add Air To Tire
On vehicles with the Tire Pressure
Monitor System (TPMS), this
message displays when the
pressure in one or more of the
vehicle’s tires is low. This message
also displays LEFT FRONT, RIGHT
FRONT, LEFT REAR, or RIGHT
REAR to indicate the location of the
low tire.
The low tire pressure warning light
will also come on. See Tire
Pressure Light
on page 5‑25.

Black plate (44,1)Cadillac CTS/CTS-V Owner Manual - 2011
5-44 Instruments and Controls
If a tire pressure message appears
on the DIC, stop as soon as you
can. Inflate the tires by adding air
until the tire pressure is equal to the
values shown on the Tire Loading
Information label. SeeTires
on
page 10‑66, Vehicle Load Limitson
page 9‑11, and Tire Pressureon
page 10‑74.
If the vehicle does not have a spare
tire, the message will display “Use
Inflator Kit in Trunk”. Use the inflator
kit to inflate the tires to the correct
pressure. See Tire Sealant and
Compressor Kit
on page 10‑92for
more information.
More than one tire pressure
message can be received at a time.
To read the other messages, press
the set/reset button.
The DIC display also shows the tire
pressure values. See Driver
Information Center (DIC)
on
page 5‑27.
Transmission Messages
Differential Hot, Reduce Speed
(CTS-V Only)
This message displays and a chime
sounds if the differential fluid
temperature exceeds 150°C
(300°F). Driving aggressively or at
high speeds can cause the
differential fluid temperature to be
higher than normal. If this message
appears, you may continue to drive
at a slower speed. If you have been
operating the vehicle under normal
driving conditions, the vehicle may
need service. See your dealer for an
inspection.

turned off. The vehicle will be in
ACC/ACCESSORY. Once the shift
lever is moved to P (Park), the
ignition needs to be turned off. If the
ignition is not turned off, the vehicle
will remain in ACC/ACCESSORY.
To avoid draining the battery, turn
the ignition to off before leaving the
vehicle.
