Precautions While Driving With Acc - Dodge Challenger 2015 Operating Information Manual

• Do not remove any screws from the sensor.
Doing so could cause an ACC system mal-
function or failure and require a sensor
realignment.
• If the sensor or front end of the vehicle is
damaged due to a collision, see your autho-
rized dealer for service.
• Do not attach or install any accessories near
the sensor, including transparent material or
aftermarket grilles. Doing so could cause an
ACC system failure or malfunction.
When the condition that deactivated the system
is no longer present, the system will return to
the "Adaptive Cruise Control Off" state and will
resume function by simply reactivating it.
NOTE:
• If the "ACC/FCW Unavailable Wipe Front
Radar Sensor" message occurs fre-
quently (e.g. more than once on every
trip) without any snow, rain, mud, or other
obstruction, have the radar sensor re-
aligned at your authorized dealer.
• Installing a snow plow, front-end protec-
tor, an aftermarket grille or modifying the
grille is not recommended. Doing so may
block the sensor and inhibit ACC/FCW
operation.
Service ACC/FCW Warning
If the system turns off, and the DID displays
"ACC/FCW Unavailable Service Required" or
"Cruise/FCW Unavailable Service Required",
there may be an internal system fault or a
temporary malfunction that limits ACC function-
ality. Although the vehicle is still drivable under
normal conditions, ACC will be temporarily un-
available. If this occurs, try activating ACC
again later, following a key cycle. If the problem
persists, see your authorized dealer.

Precautions While Driving With ACC

In certain driving situations, ACC may have
detection issues. In these cases, ACC may
brake late or unexpectedly. The driver needs to
stay alert and may need to intervene.
Towing A Trailer
Towing a trailer is not advised when using ACC.
Offset Driving
ACC may not detect a vehicle in the same lane
that is offset from your direct line of travel, or a
vehicle merging in from a side lane. There may
not be sufficient distance to the vehicle ahead.
The offset vehicle may move in and out of the
line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.
Offset Driving Condition Example
Turns And Bends
When driving on a curve with ACC engaged, the
system may decrease the vehicle speed and
acceleration for stability reasons, with no target
vehicle detected. Once the vehicle is out of the
curve the system will resume your original Set
Speed. This is a part of normal ACC system
functionality.
