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.

It cannot be reset accurately until
the next oil change. To reset the
engine oil life system, SeeEngine
Oil Life System
on page 10‑14. The
system is reset when 100%
displays.
Units
Select to display English or Metric
units of measure. Press the set/
reset button to select when units is
displayed.
Parking Assist
If the vehicle has the Ultrasonic
Rear Parking Assist (URPA) system,
this display allows the system to be
turned on or off. Once in this
display, press the set/reset button to
select between On or Off. The
URPA system automatically turns
back on after each vehicle start.
When the URPA system is turned
off and the vehicle is shifted out of
P (Park), the DIC displays the
Parking Assist Off message as a
reminder that the system has been
turned off. See Object Detection System Messages
on page 9‑42and
Ultrasonic Parking Assiston
page 9‑42for more information.
Tire Pressure
Tire pressure is displayed in the DIC
for each tire in either
kilopascals (kPa) or pounds per
square inch (psi). Press the vehicle
information button until the DIC
displays Front Tire kPa (PSI) Left ##
Right ##. Press the vehicle
information button again until the
DIC displays Rear Tire kPa (PSI)
Left ## Right ##.
If a low tire pressure condition is
detected by the system while
driving, a message advises to add
air to a specific tire displays. See
Tire Pressure
on page 10‑74and
Tire Messageson page 5‑43for
more information.
Battery Voltage
This display shows the current
battery voltage. The vehicle's
charging system regulates voltage
based on the state of the battery. The battery voltage may fluctuate
when viewing this information on the
DIC. This is normal.
If there is a problem with the battery
charging system, the charging
system light illuminates and/or the
DIC displays a message. See
Charging System Light
on
page 5‑19, Battery Voltage and
Charging Messageson page 5‑31and Battery Load Managementon
page 6‑6for more information.
Calibrate Compass
The vehicle may have this feature.
The compass can be manually
calibrated. To calibrate the compass
through the DIC, see “DIC
Compass” later in this section.
Change Compass Zone
The vehicle may have this feature.
To change the compass zone
through the DIC, see “DIC
Compass” later in this section.

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.
To acknowledge the message,
press
V. The message reappears
and a chime sounds every
two minutes until this condition
changes. If you do not clear the
message, it will remain on until the
condition changes.
Service Transmission
This message displays when there
is a problem with the vehicle's
transmission. Have the vehicle
serviced by your dealer.
Shift To Park (Automatic
Transmission Only)
If the vehicle has the keyless
access system, this message
displays if the vehicle is not in
P (Park) while the engine is being
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.

10-82 Vehicle Care
After the tires have been
rotated, adjust the front and rear
inflation pressures as shown on
the Tire and Loading Information
label. SeeTire Pressure
on
page 10‑74
and Vehicle Load
Limits
on page 9‑11.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation
on page 10‑77.
Make certain that all wheel nuts
are properly tightened. See
“Wheel Nut Torque” under
Capacities and Specifications
on
page 12‑2
.
{WARNING
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
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, 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. See If a Tire Goes Flat
on page 10‑90.
Lightly coat the center of the wheel
hub with bearing grease after a
wheel change or tire rotation to
prevent corrosion or rust build-up.
Do not get grease on the flat wheel
surface or on the wheel nuts or
bolts.
When It Is Time for New
Tires
Various factors, such as
maintenance, temperatures, driving
speeds, vehicle loading, and road
conditions influence when you need
new tires.
One way to tell when it is time for
new tires is to check the treadwear
indicators, which appear when the
tires have only 1.6 mm (1/16 in) or
less of tread remaining. See Tire

Scheduled
Maintenance
When the Change Engine Oil
Soon Message Displays
Change engine oil and filter. See
Engine Oilon page 10‑11.An
Emission Control Service.
When the “Change Engine Oil
Soon” message displays, service is
required for the vehicle as soon as
possible, within the next 1 000 km/
600 miles. If driving under the best
conditions, the engine oil life system
might not indicate the need for
vehicle service for more than a year.
The engine oil and filter must be
changed at least once a year and
the oil life system must be reset.
Your dealer has trained service
technicians who will perform this
work and reset the system. If the
engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 miles since
the last service. Reset the oil life system whenever the oil is changed.
