detect another vehicle's lamps because
of any of the following:
.The other vehicle's lamps are
missing, damaged, obstructed from
view, or otherwise undetected.
.The other vehicle's lamps are
covered with dirt, snow, and/or road
spray.
.The other vehicle's lamps cannot be
detected due to dense exhaust,
smoke, fog, snow, road spray, mist,
or other airborne obstructions.
.The vehicle's windshield is dirty,
cracked, or obstructed by something
that blocks the view of the light
sensor.
.The vehicle is loaded such that the
front end points upward, causing
the light sensor to aim high and not
detect headlamps and taillamps.
.The vehicle is being driven on
winding or hilly roads.

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
cover on 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.

1. Front Lower Control Arm Deflector
2. 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) 0346.
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.

launching the vehicle. This feature is
intended for use during closed course
race events where consistent zero to
60 and quarter mile times are
desirable.
Launch Control is only available when
the following criteria are met:
.Competitive Driving Mode is
selected or any of the PTM modes
are selected. The traction off light
comes on in the instrument cluster
and the appropriate DIC message
displays.
.The vehicle is not moving.
.The steering wheel is pointing
straight.
Automatic Transmissions
.The brake pedal is firmly pressed to
the floor, equivalent to a panic
brake event.
.The accelerator pedal is rapidly
applied to wide open throttle. If the
vehicle rolls due to wide open
throttle, release the throttle, press
the brake pedal more firmly, and
reapply the accelerator to wide open
throttle.Launch Control will initially limit
engine speed as you rapidly apply the
accelerator pedal to wide open
throttle. Allow the engine rpm to
stabilize. A smooth, quick release of
the brake pedal, while maintaining the
fully pressed accelerator pedal, will
manage wheel slip.
After the vehicle is launched, the
system continues in Competitive
Driving Mode or PTM.
Competitive Driving Mode, PTM, and
Launch Control are systems designed
for a closed course race track and not
intended for public roads. The systems
are not intended to compensate for
lack of driver experience or familiarity
with the race track.
Limited-Slip Differential
If equipped, the Electronic
Limited-Slip Differential (eLSD) is
automatically activated. eLSD actively
monitors vehicle sensors and driver
inputs to determine the amount of
change for the conditions. With eLSD,
the vehicle has:
.Enhanced high-speed control.
.Improved traction through corners,
allowing more acceleration.
.More precise steering.
.Increased vehicle agility.
.Integration with StabiliTrak/
Electronic Stability Control (ESC).
For vehicles with eLSD, driven under
severe conditions, the rear axle fluid
should be changed. See Competitive
Driving Mode 0264 and
Maintenance Schedule 0408.
Cruise Control
{
Warning
Cruise control can be dangerous
where you cannot drive safely at a
steady speed. Do not use cruise
control on winding roads or in
heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise
control on slippery roads.

going downhill, the cruise control
system may automatically brake to
slow the vehicle down. Also, you may
have to brake or shift to a lower gear
to keep your speed down. If the brake
pedal is applied, cruise control
disengages.
Ending Cruise Control
There are five ways to end cruise
control:
.Step lightly on the brake pedal.
.Press*.
.Shift the transmission to
N (Neutral).
.Press the clutch pedal for several
seconds or shift to Neutral (manual
transmissions).
.PressJ.
Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if the
ignition is turned off.
Adaptive Cruise Control
(Advanced)
If equipped, Adaptive Cruise Control
(ACC) allows the cruise control set
speed and following gap to be
selected. Read this entire section
before using this system. The
following gap is the following time
between your vehicle and a vehicle
detected directly ahead in your path,
moving in the same direction. If no
vehicle is detected in your path, ACC
works like regular cruise control. ACC
uses camera and radar sensors. See
Radio Frequency Statement 0438.
If a vehicle is detected in your path,
ACC can speed up the vehicle or apply
limited, moderate braking to maintain
the selected following gap. To
disengage ACC, apply the brake. If the
Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system activates while ACC is
engaged, ACC may automatically
disengage. See Traction Control/
Electronic Stability Control 0257. When
road conditions allow ACC to be safely
used, ACC can be turned back on. ACC will not engage if the TCS or
StabiliTrak/ESC electronic stability
control system is disabled.
ACC can reduce the need for you to
frequently brake and accelerate,
especially when used on expressways,
freeways, and interstate highways.
When used on other roads, you may
need to take over the control of
braking or acceleration more often.
{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver”
in this section.
Complete attention is always
required while driving and you
should be ready to take action and
apply the brakes. See Defensive
Driving 0210.
