2017 DODGE DURANGO Owners Manual

read “ACC/FCW Limited Functionality Clean Front Wind-
shield” and the system will have degraded performance.
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” message can sometimes be displayed while driving
in adverse weather conditions. The ACC/FCW system will
recover after the vehicle has left these areas. Under rare
conditions, when the camera is not tracking any vehicles or
objects in its path this warning may temporarily occur.
If weather conditions are not a factor, the driver should
examine the windshield and the camera located on the
back side of the inside rear view mirror. They may require
cleaning or removal of an obstruction.
When the condition that created limited functionality is no
longer present, the system will return to full functionality.
NOTE:If the “ACC/FCW Limited Functionality Clean
Front Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain, mud, or
other obstruction, have the windshield and forward facing
camera inspected at your authorized dealer.Service ACC/FCW Warning
If the system turns off, and the Instrument Cluster Display
reads “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 functionality. Although the vehicle is still
drivable under normal conditions, ACC will be temporar-
ily unavailable. If this occurs, try activating ACC again
later, following an ignition 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.
Turns And Bends
When driving on a curve with ACC engaged, the system
may decrease the vehicle speed and acceleration for stabil-
ity 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.
NOTE:On tight turns ACC performance may be limited.

Using ACC On Hills
When driving on hills, ACC may not detect a vehicle in
your lane. Depending on the speed, vehicle load, traffic
conditions, and the steepness of the hills, ACC perfor-
mance may be limited.
Lane Changing
ACC may not detect a vehicle until it is completely in the
lane in which you are traveling. In the illustration shown,
ACC has not yet detected the vehicle changing lanes and it
may not detect the vehicle until it’s too late for the ACC
system to take action. ACC may not detect a vehicle until it
is completely in the lane. There may not be sufficient
distance to the lane-changing vehicle. Always be attentive
and ready to apply the brakes if necessary.

Narrow Vehicles
Some narrow vehicles traveling near the outer edges of the
lane or edging into the lane are not detected until they have
moved fully into the lane. There may not be sufficient
distance to the vehicle ahead.
Stationary Objects And Vehicles
ACC does not react to stationary objects and stationary
vehicles. For example, ACC will not react in situations
where the vehicle you are following exits your lane and the
vehicle ahead is stopped in your lane. Always be attentive
and ready to apply the brakes if necessary.

General Information
This vehicle has systems that operate on radio frequency
that comply with Part 15 of the Federal Communications
Commission (FCC) rules and with Industry Canada Stan-
dards RSS- GEN/210/220/310.
Operation is subject to the following two conditions:
1. The device may not cause harmful interference.
2. The device must accept any interference received, in-cluding interference that may cause undesired operation
of the device.
Changes or modifications to any of these systems by other
than an authorized service facility could void authorization
to use this equipment.
Normal (Fixed Speed) Electronic Speed Control
Mode
In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Electronic Speed Control mode is available
for cruising at fixed speeds. The Normal (Fixed Speed)
Electronic Speed Control mode is designed to maintain a
set cruising speed without requiring the driver to operate
the accelerator. Electronic Speed Control can only be oper-
ated if the vehicle speed is above 20 mph (32 km/h).
To change between the different control modes, push the
ADAPTIVE CRUISE CONTROL (ACC) ON/OFF button
which turns the ACC and the NORMAL (Fixed Speed)
ELECTRONIC SPEED CONTROL OFF. Pushing of the NOR-
MAL (Fixed Speed) ELECTRONIC SPEED CONTROL ON/
OFF button will result in turning ON (changing to) the
Normal (Fixed Speed) Electronic Speed Control mode.
WARNING!
In the normal Cruise Control mode, the system will not
react to vehicles ahead. In addition, the proximity warn-
ing does not activate and no alarm will sound even if you
are too close to the vehicle ahead since neither the
presence of the vehicle ahead nor the vehicle-to vehicle
distance is detected. Be sure to maintain a safe distance
between your vehicle and the vehicle ahead. Always be
aware which mode is selected.

FORWARD COLLISION WARNING (FCW) WITH
MITIGATION — IF EQUIPPED
Forward Collision Warning (FCW) With Mitigation
Operation
The Forward Collision Warning (FCW) system with miti-
gation provides the driver with audible warnings, visual
warnings (within the Instrument Cluster Display), and
may apply a brake jerk to warn the driver when it detects
a potential frontal collision. The warnings and limited
braking are intended to provide the driver with enough
time to react, avoid or mitigate the potential collision. NOTE:
FCW monitors the information from the forward
looking sensors as well as the Electronic Brake Controller
(EBC), to calculate the probability of a forward collision.
When the system determines that a forward collision is
probable, the driver will be provided with audible and
visual warnings and may provide a brake jerk warning. If
the driver does not take action based upon these progres-
sive warnings, then the system will provide a limited level
of active braking to help slow the vehicle and mitigate the
potential forward collision. If the driver reacts to the
warnings by braking and the system determines that the
driver intends to avoid the collision by braking but has not
applied sufficient brake force, the system will compensate
and provide additional brake force as required.
If a Forward Collision Warning with Mitigation event
begins at a speed below 26 mph (42 km/h), the system may
provide the maximum or partial braking to mitigate the
potential forward collision. If the Forward Collision Warn-
ing with Mitigation event stops the vehicle completely, the
system will hold the vehicle at a standstill for two seconds
and then release the brakes.
