238 Climate Controls
Sensors
The solar sensor, located in
the defrost grille in the middle
of the instrument panel,
monitors the solar heat. Do
not cover the solar sensor or
the system will not work
properly.
There is also an exterior
temperature sensor behind
the front grille. This sensor
reads the outside air
temperature and helps
maintain the temperature
inside the vehicle. Any coveron the front of the vehicle
could cause a false reading in
the displayed temperature.
The climate control system
uses the information from
these sensors to maintain
comfort settings by adjusting
the outlet temperature, fan
speed, and air delivery mode.
The system may also supply
cooler air to the side of the
vehicle facing the sun. The
recirculation mode will also be
used as needed to maintain
cool outlet temperatures.
Afterblow Feature
If equipped, under certain
conditions, the fan may stay
on or may turn on and off
several times after you turn
off and lock the vehicle. This is
normal.
Air Vents
Adjustable air vents are in the
center and on the sides of the
instrument panel, and on the
rear of the center console
storage.
Move the slider knobs to
change the direction of or to
close off the airflow.
Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at
the base of the windshield
that could block the flow of
air into the vehicle.
.Clear snow off the hood to
improve visibility and help
decrease moisture drawn
into the vehicle.
.Keep the path under the
front seats clear of objects
to help circulate the air
inside of the vehicle more
effectively.
.Use of non-GM approved
hood deflectors can
adversely affect the
performance of the system.

250 Driving and Operating
3. Front Brake Cooling Duct
Brake Pad Wear Sensors
If equipped, the brake pad
wear sensors need to be
removed from the brake
calipers prior to any track or
racing event. The original
sensors can be reinstalled if
significant brake pad wear is
not observed. Refer to Brake
Pad Life System (If Equipped)
0 403. If the sensors are not
reinstalled after the track
event, install brake pad wear
sensor plugs. See your dealer. The V-Series Blackwing is
equipped with brake pad wear
sensors which are track
capable and should not be
disabled for track and racing.
A message will display in the
Driver Information Center
(DIC) when the brake pads
show excessive wear.
Brake Fluid
Replace existing brake fluid
with a qualified DOT 4 high
performance brake fluid from
a sealed container. Brake fluid
with a dry boiling point >310 °C
(590 °F) is qualified. If high
performance brake fluid is
used, replace it with GM
approved brake fluid before
driving on public roads. If high
performance brake fluid is in
the vehicle and the age of the
brake fluid is over a month old
or unknown, replace the brake
fluid before track events and
competitive driving. Do not use
silicone or DOT 5 brake fluids.
It is critical to disconnect the
battery before bleeding the
system, replacing the pads,
or any other work. The battery
must be disconnected to
prevent the brake master
cylinder from pressurizing the
hydraulic system during its
automated self diagnostic
tests that can possibly occur
when a door is opened or the
remote key is present.
Check the fluid level before
each competitive driving
event.
Brake System Flushing &
Bleeding
The J56 brake system
requires specific processes
for bleeding and fluid flushing.
These can be found in the
service manual.
Properly bleeding the brake
system is required for proper
operation of the hydraulic
brake system.
