Climate Controls 8-5
Sensors
The solar sensor located on the
instrument panel, near the
windshield, monitors the solar heat.
The interior temperature sensor,
located on the instrument panel to
the right of the steering wheel,
measures the temperature of the air
inside the vehicle.
The climate control system uses the
information from these sensors to
adjust the fan speed and the air
delivery, in order to maintain the
selected temperature. The system
may also supply cooler air to the
side of the vehicle facing the sun.
The recirculation mode will also be
activated, as necessary.
Do not cover the sensors or the
automatic climate control system will
not work properly.Air Quality Sensor
For vehicles with an air quality
sensor, the climate control system
adjusts to limit some exhaust fumes
from being pulled inside your
vehicle.
Press the AUTO button on the
climate control to activate the air
quality sensor. The recirculation
indicator light comes on when poor
quality air is detected. The air
quality sensor will not maintain
recirculation for an extended period
to prevent the air inside the vehicle
from becoming too dry or stuffy.
Under certain conditions, the air
quality sensor will not activate
recirculation, such as during cold
weather or with odors, like skunk. To
limit odors manually, press
Muntil
the condition has passed.
The air quality sensor system does
not protect against carbon monoxide
(CO), which you cannot see or
smell. See Engine Exhaust on
page 9‑26.

Object Detection
Systems
Ultrasonic Parking Assist
If available, the Ultrasonic Rear
Parking Assist (URPA) system
assists the driver with parking
and avoiding objects while in
R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph).
The sensors on the rear bumper
detect objects up to 2.5 m (8 ft)
behind the vehicle, and at least
25 cm (10 in) off the ground.
{WARNING
The URPA system does not
detect pedestrians, bicyclists,
animals, or any other objects
located below the bumper or that
are too close or too far from the
vehicle. To prevent injury, death,
or vehicle damage, even with(Continued)
WARNING (Continued)
URPA, always check behind the
vehicle and check all mirrors
before backing.
How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in), the beeping is a
continuous tone for five seconds.
To be detected, objects must be at
least 25 cm (10 in) off the ground
and below trunk or liftgate level.
Objects must also be within 2.5 m (8 ft) of the rear bumper. This
distance may be less during warmer
or humid weather.
Turning the System On and Off
The system can be disabled through
the Driver Information Center (DIC).
See
“Parking Assist” underDriver
Information Center (DIC) on
page 5‑27 for more information.
URPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
PARKING ASSIST OFF: This
message occurs if the driver
disables the system or if vehicle is
driven above 8 km/h (5 mph) in
R (Reverse).
SERVICE PARKING ASSIST: If
this message occurs, take the
vehicle to your dealer to repair the
system.

PARK ASSIST BLOCKED SEE
OWNER'S MANUAL:If the URPA
system does not activate due to a
temporary condition, this message
displays on the DIC. This can occur
under the following conditions:
.The driver has disabled the
system.
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice and slush. For cleaning
instructions, see Exterior Care
on page 10‑110.
.The park assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold
weather. The message may not
clear until the frost or ice has
melted.
.A trailer was attached to the
vehicle, or an object was
hanging out of the trunk or
liftgate during the last drive
cycle. Once the object is
removed, URPA will return to
normal operation.
.A tow bar is attached to the
vehicle.
.The bumper is damaged. Take
the vehicle to your dealer to
repair the system.
.Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
Side Blind Zone
Alert (SBZA)
The vehicle may have a Side Blind
Zone Alert (SBZA) system. Read
this entire section before using the
system.
{WARNING
SBZA does not detect vehicles
rapidly approaching outside of the
side blind zones, pedestrians,
bicyclists, or animals. Failure to
use proper care when changing
lanes may result in injury, death,
or vehicle damage. Always check
for other vehicles and use the
turn signals when changing lanes.
When the system detects a vehicle
in the side blind zone, amber SBZA
displays will light up in the side
mirrors. This indicates that it may be
unsafe to change lanes. Before
making a lane change, always
check the SBZA display, check the

Black plate (46,1)Cadillac CTS/CTS-V Owner Manual (Include Mex) - 2012
9-46 Driving and Operating
outside and rearview mirrors, look
over your shoulder for vehicles and
hazards, and use the turn signal.
SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, or
3.5 m (11 ft). This zone starts at
each side mirror and goes back
approximately 5.0 m (16 ft). The
height of the zone is approximately
between 0.5 m (1.5 ft) and 2.0 m
(6 ft) off the ground.
The SBZA detection zones do not
change if the vehicle is towing a
trailer. So be extra careful when
changing lanes while towing a
trailer.How the System Works
Left Side Mirror
DisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror displays will briefly
come on to indicate that the system
is operating. While driving forward,
the left or right side mirror SBZA
display will light up if a vehicle is
detected in that blind zone. If you
activate a turn signal and a vehicle
has been detected on the same
side, the SBZA display will flash to
give you extra warning not to
change lanes.
At speeds less than 32 km/h
(20 mph), SBZA displays may not
come on when approaching or
passing other vehicles. SBZA
displays may come on when a vehicle you have passed remains in
or drops back into the detection
zone for more than two seconds.
SBZA can be disabled through the
Driver Information Center (DIC).
See
Driver Information Center (DIC)
on page 5‑27 for more information.
If the SBZA is disabled by the
driver, the SBZA mirror displays will
not light up during normal driving.
When the System Does Not Seem
to Work Properly
Occasional missed alerts can occur
under normal circumstances and will
increase in wet conditions. The
system does not need to be
serviced due to an occasional
missed alert. The number of missed
alerts will increase with increased
rainfall or road spray.
If the SBZA displays do not light up
when the system is on and vehicles
are in the blind zone, the system
may need service. Take the vehicle
to your dealer.

Black plate (47,1)Cadillac CTS/CTS-V Owner Manual (Include Mex) - 2012
Driving and Operating 9-47
SBZA is designed to ignore
stationary objects; however, the
system may occasionally light up
due to guard rails, signs, trees,
shrubs, and other stationary objects.
This is normal system operation; the
vehicle does not need service.
SBZA does not operate when the
left or right corners of the rear
bumper are covered with mud,
dirt, snow, ice, or slush, or in
heavy rainstorms. For cleaning
instructions, seeExterior Care on
page 10‑110. If the infotainment
display still shows the SIDE
BLIND ZONE ALERT SYSTEM
TEMPORARILY UNAVAILABLE
message after cleaning the bumper,
see your dealer.
The SBZA displays may remain on
if a trailer is attached to the vehicle,
or 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 driver will not be able to
turn SBZA back on using the DIC.
The SIDE BLIND ZONE ALERT ON
option will not be selectable if the
conditions for normal system
operation are not met. Until normal
operating conditions for SBZA are
met, you should not rely upon SBZA
while driving.
SBZA Messages
The following messages may
appear on the infotainment display:
SIDE BLIND ZONE ALERT
SYSTEM OFF:
This message
indicates that the driver has turned
the system off.
SIDE BLIND ZONE ALERT
SYSTEM TEMPORARILY
UNAVAILABLE: This message
indicates that the SBZA system is
disabled because the sensor is
blocked and cannot detect vehicles
in the blind zone. The sensor may be blocked by mud, dirt, snow, ice,
or slush. This message may also
activate during heavy rain or due to
road spray. The vehicle does not
need service. For cleaning, see
Exterior Care on page 10‑110.
SERVICE SIDE BLIND ZONE
ALERT SYSTEM:
If this message
appears, both SBZA displays will
remain on indicating there is a
problem with the SBZA system.
If these displays remain on after
continued driving, the system needs
service. Take the vehicle to your
dealer.
