If the SBZA displays do not light up
when vehicles are in the blind zone
and the system is clean, the system
may need service. Take the vehicle
to your dealer.
The SBZA displays may remain on
if a trailer is attached to the vehicle,
or if a bicycle or object is extending
out to either side of the vehicle.
When SBZA is disabled for any
reason other than the driver turning
it off, the Side Blind Zone Alert On
option will not be available on the
personalization menu.

Lane Departure
Warning (LDW)
LDW may help avoid crashes due to
unintentional lane departures. It may
provide a warning if the vehicle is
crossing a lane without using a turn
signal. LDW uses a camera sensor
to detect the lane markings. It only
operates at speeds of 56 km/h (35
mph) or greater.
When the vehicle crosses a
detected lane marking, the LDW
indicator will flash and either three
beeps sound or three Safety Alert
Seat pulses will occur on the left or
right side of the seat, depending on
the lane departure direction. LDW
will not warn if the turn signal is on
or if a sharp maneuver is made.
{WARNING
The LDW system is an aid to help
the vehicle stay in the driving
lane. It does not steer the vehicle.
The LDW system may not:
.Provide enough time to avoid
a crash.
.Detect lane markings under
bad weather conditions or if
the windshield is dirty.
.Detect lane markings and will
not detect road edges.
.Warn that the vehicle is
crossing a lane marking if the
system does not detect the
lane marking.
If LDW only detects lane
markings on one side of the road,
it will only warn you when
departing the lane on the side
where it has detected a lane
marker. Even with LDW, always
keep your attention on the road (Continued)

Black plate (54,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
9-54 Driving and Operating
WARNING (CONTINUED)
and maintain proper vehicle
position within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield clean and do not use
LDW in bad weather conditions.
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press
@on
the center stack to the left of the
infotainment screen. The control
indicator will light when LDW is on.
When the vehicle is started, the
LDW indicator on the instrument
cluster will come on briefly.
If LDW is on, the LDW indicator will
appear green if the system detects
a left or right lane marking. If the
vehicle crosses a detected lane
marking without using the turn
signal, this indicator will change to
amber and flash. In addition, three
beeps will be sounded from the left
or right speaker, or the Safety Alert
Seat will pulse three times on either
the left or right side of the seat,
depending on the lane departure
direction.
When the System Does Not
Seem to Work Properly
If the LDW symbol does not appear:
.The lane markings on the road
may not be seen.
.The camera sensor may be
blocked by dirt, snow, or ice.
.The windshield may be
damaged.
.The weather may be limiting
visibility.
This is normal operation; the vehicle
does not need service. Clean the
windshield.
Lane markings may not be detected
on curves, highway exit ramps,
or hills; or due to poor visibility.
If the LDW camera system does not
seem to operate properly, cleaning
the outside of the windshield in front
of the camera sensor may correct
the issue.
{WARNING
If the LDW camera sensor is
blocked by dirt, snow, or ice, or if
the headlamps are not cleaned or
properly aimed, or if the
windshield is dirty or damaged, it
may not detect the lanes ahead.
LDW may not help avoid a crash
under these conditions. Keep the
headlamps cleaned and properly
aimed and the windshield clean.

Tire Pressure for
High-Speed Operation
{WARNING
Driving at high speeds, 160 km/h
(100 mph) or higher, puts an
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
You could have a crash and you
or others could be killed. Some
high-speed rated tires require
inflation pressure adjustment for
high-speed operation. When
speed limits and road conditions
are such that a vehicle can be
driven at high speeds, make sure
the tires are rated for high-speed
operation, in excellent condition,
and set to the correct cold tire
inflation pressure for the
vehicle load.Vehicles with P245/45R19 98V size
tires require inflation pressure
adjustment when driving the vehicle
at speeds of 160 km/h (100 mph) or
higher. Set the cold inflation
pressure to 260 kPa (38 psi).
Vehicles with P245/40R20 95V size
tires require inflation pressure
adjustment when driving the vehicle
at speeds of 160 km/h (100 mph) or
higher. Set the cold inflation
pressure to 270 kPa (39 psi).
Professional vehicles with 235/
55R18 104H size tires require
inflation pressure adjustment when
driving the vehicle at speeds of
160 km/h (100 mph) or higher. Set
the cold inflation pressure to
40 kPa (6 psi) above the
recommended cold tire pressure
shown on the Tire and Loading
Information label for the 235/
55R18 104H size tires.
Return the tires to the
recommended cold tire inflation
pressure when high-speed driving has ended. See
Vehicle Load Limits
on page 9‑10 andTire Pressure on
page 10‑41.
Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)

Black plate (44,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
10-44 Vehicle Care
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire
pressure telltale when one or more
of your tires is significantly
under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on a
significantly under-inflated tire
causes the tire to overheat and can
lead to tire failure. Under-inflation
also reduces fuel efficiency and tire
tread life, and may affect the
vehicle's handling and stopping
ability.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.

Tire Pressure Monitor
Operation on page 10‑44.

Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly. The TPMS

Black plate (45,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
Vehicle Care 10-45
sensors monitor the air pressure in
the tires and transmits the tire
pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
on the instrument cluster. 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 9‑10.
A message to check the pressure in
a specific tire displays in the Driver
Information Center (DIC). The low
tire pressure warning light and the
DIC warning message come on at
each ignition cycle until the tires are
inflated to the correct inflation pressure. Using the DIC, tire
pressure levels can be viewed. For
additional information and details
about the DIC operation and
displays see
Driver Information
Center (DIC) on page 5‑27.
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
could be an early indicator that the
air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information
label, attached to your vehicle,
shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. See Vehicle Load
Limits on page 9‑10, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10‑41.
The TPMS can warn about a low
tire pressure condition but it does
not replace normal tire maintenance. See
Tire Inspection
on page 10‑48, Tire Rotation on
page 10‑48 andTires on
page 10‑34.
Notice: Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the
TPMS sensors. TPMS sensor
damage caused by using an
incorrect tire sealant is not
covered by the vehicle warranty.
Always use only the
GM-approved tire sealant
available through your dealer or
included in the vehicle.
Factory-installed Tire Inflator Kits
use a GM approved liquid tire
sealant. Using non-approved tire
sealants could damage the TPMS
sensors. See Tire Sealant and
Compressor Kit on page 10‑57 for
information regarding the inflator kit
materials and instructions.

10-46 Vehicle Care
TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tire warning light flashes for
about one minute and then stays on
for the remainder of the ignition
cycle. A DIC warning message also
displays. The malfunction light and
DIC warning message come on at
each ignition cycle until the problem
is corrected. Some of the conditions
that can cause these to come
on are:
.One of the road tires has been
replaced with the spare tire. The
spare tire does not have a
TPMS sensor. The malfunction
light and DIC message should
go off after the road tire is
replaced and the sensor
matching process is performed
successfully. See“TPMS Sensor
Matching Process” later in this
section.
.The TPMS sensor matching
process was not done or not
completed successfully after
rotating the tires. The
malfunction light and the DIC
message should go off after
successfully completing the
sensor matching process. See
"TPMS Sensor Matching
Process" later in this section.
.One or more TPMS sensors are
missing or damaged. The
malfunction light and the DIC
message should go off when the
TPMS sensors are installed and
the sensor matching process is
performed successfully. See
your dealer for service.
.Replacement tires or wheels do
not match the original equipment
tires or wheels. Tires and wheels
other than those recommended
could prevent the TPMS from
functioning properly. See Buying
New Tires on page 10‑50.
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly it cannot detect or signal a
low tire condition. See your dealer
for service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
vehicle’s tires or replacing one or
more of the TPMS sensors. The
TPMS sensor matching process
should also be performed after
replacing a spare tire with a road
tire containing the TPMS sensor.
The malfunction light and the DIC
message should go off at the next
ignition cycle. The sensors are
matched to the tire/wheel positions,

Black plate (47,1)Cadillac XTS Owner Manual - 2013 - 1st - 4/13/12
Vehicle Care 10-47
using a TPMS relearn tool, in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear.
See your dealer for service or to
purchase a relearn tool.
There are two minutes to match the
first tire/wheel position, and
five minutes overall to match all four
tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Place the vehicle power mode inON/RUN/START. See Ignition
Positions on page 9‑15.
3. Make sure the Tire Pressure info display option is turned on. The
info displays on the DIC can be
turned on and off through the
Settings menu. See Driver
Information Center (DIC) on
page 5‑27. 4. Under the Settings menu select
Display Options and then Tire
Pressure using the five-way DIC
control on the right side of the
steering wheel. See Driver
Information Center (DIC) on
page 5‑27.
5. Press and hold the SEL button located in the center of the
five-way DIC control.
The horn sounds twice to signal
the receiver is in relearn mode
and the TIRE LEARNING
ACTIVE message displays on
the DIC screen.
6. Start with the driver side front tire.
7. Place the relearn tool against the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position. 8. Proceed to the passenger side
front tire, and repeat the
procedure in Step 7.
9. Proceed to the passenger side rear tire, and repeat the
procedure in Step 7.
10. Proceed to the driver side rear tire, and repeat the procedure
in Step 7. The horn sounds two
times to indicate the sensor
identification code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
11. Press STOP to turn the ignition off.
12. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.
