2018 DODGE DURANGO Owners Manual

STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce fuel con-
sumption. The system will stop the engine automatically
during a vehicle stop if the required conditions are met.
Releasing the brake pedal or pressing the accelerator pedal
will automatically re-start the engine.
This vehicle has been upgraded with a heavy duty starter,
enhanced battery, and other upgraded engine parts, to
handle the additional engine starts.
Automatic Mode
The Stop/Start feature is enabled after every
normal customer engine start. At that time, the
system will go into STOP/START READY and if
all other conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE “Autostop” mode.
To Activate The Autostop Mode, The Following Must
Occur:
• The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in the
instrument cluster display within the Stop/Start section.
Refer to “Instrument Cluster” in “Getting To Know Your
Instrument Panel” for further information. •
The vehicle must be completely stopped.
• The shifter must be in a forward gear and the brake
pedal depressed.
The engine will shut down, the tachometer will move to
the zero position and the Stop/Start telltale will illuminate
indicating you are in Autostop. Customer settings will be
maintained upon return to an engine running condition.
Refer to the “Stop/Start System” in the “Starting And
Operating” section for further information.
Possible Reasons The Engine Does Not Autostop
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
Detailed information about the operation of the Stop/Start
system may be viewed in the instrument cluster display
Stop/Start Screen. In the following situations, the engine
will not stop:
• Driver ’s seat belt is not buckled.
• Driver ’s door is not closed.
• Battery temperature is too warm or cold.
• Battery charge is low.
• The vehicle is on a steep grade.

Other Factors Which Can Inhibit Autostop Include:
• Accelerator pedal input.
• Engine temp too high.
• 5 mph (8 km/h) threshold not achieved from previous
AUTOSTOP.
• Steering angle beyond threshold.
• ACC is on and speed is set.
It may be possible for the vehicle to be driven several times
without the STOP/START system going into a STOP/
START READY state under more extreme conditions of the
items listed above.To Start The Engine While In Autostop Mode
While in a forward gear, the engine will start when the
brake pedal is released or the throttle pedal is depressed.
The transmission will automatically re-engage upon en-
gine restart.
Conditions That Will Cause The Engine To Start Auto-
matically While In Autostop Mode:
• The transmission selector is moved out of DRIVE.
• To maintain cabin temperature comfort.
• HVAC is set to full defrost mode.
• HVAC system temperature or fan speed is manually
adjusted.
• Battery voltage drops too low.
• Low brake vacuum (e.g. after several brake pedal appli-
cations).
• STOP/START OFF switch is pushed.
• A STOP/START system error occurs.

To Set A Desired Speed
Turn the Speed Control on. When the vehicle has reached
the desired speed, push the SET (+) or SET (-) button and
release. Release the accelerator and the vehicle will operate
at the selected speed. Once a speed has been set, a message
“CRUISE CONTROL SET TO MPH (km/h)” will appear
indicating what speed was set. A cruise indicator lamp,
along with set speed will also appear and stay on in the
instrument cluster when the speed is set.
To Vary The Speed Setting
To Increase Speed
When the Speed Control is set, you can increase speed by
pushing the SET(+)button.
The driver’s preferred units can be selected through the
instrument cluster display. Refer to “Getting To Know Your
Instrument Panel” for more information. The speed incre-
ment shown is dependant on the chosen speed unit of U.S.
(mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the SET (+)button once will result ina1mph
increase in set speed. Each subsequent tap of the button
results in an increase of 1 mph. •
If the button is continually pushed, the set speed will
continue to increase until the button is released, then the
new set speed will be established.
Metric Speed (km/h)
• Pushing the SET (+)button once will result in a 1 km/h
increase in set speed. Each subsequent tap of the button
results in an increase of 1 km/h.
• If the button is continually pushed, the set speed will
continue to increase until the button is released, then the
new set speed will be established.
To Decrease Speed
When the Speed Control is set, you can decrease speed by
pushing the SET (-)button.
The driver’s preferred units can be selected through the
instrument cluster display. Refer to “Getting To Know Your

new set speed will be established.
To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
NOTE: The Speed Control system maintains speed up and
down hills. A slight speed change on moderate hills is
normal.
On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Speed Control.
WARNING!
Speed Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control and have an accident. Do not use Speed Control
in heavy traffic or on roads that are winding, icy,
snow-covered or slippery.
To Resume Speed
To resume a previously set speed, push the RES button and
release. Resume can be used at any speed above 20 mph
(32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC button,
or normal brake pressure while slowing the vehicle will
deactivate the Speed Control without erasing the set speed
from memory.
Pushing the on/off button or turning the ignition switch
OFF erases the set speed from memory.
292 STARTING AND OPERATING

ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving con-
venience provided by cruise control while traveling on
highways and major roadways. However, it is not a safety
system and not designed to prevent collisions.Speed
Control function performs differently. Please refer to the
proper section within this chapter.
ACC will allow you to keep cruise control engaged in light
to moderate traffic conditions without the constant need to
reset your cruise control. ACC utilizes a radar sensor and a
forward facing camera designed to detect a vehicle directly
ahead of you.
NOTE:
• If the sensor does not detect a vehicle ahead of you, ACC
will maintain a fixed set speed.
• If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or accelerate (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead. The Cruise Control system has two control modes:
•
Adaptive Cruise Control mode for maintaining an ap-
propriate distance between vehicles.
• Normal (Fixed Speed) Cruise Control mode for cruising
at a constant preset speed. For additional information,
refer to “Normal (Fixed Speed) Cruise Control Mode” in
this section.
NOTE:
Normal (Fixed Speed) Cruise Control will not react to
preceding vehicles. Always be aware of the mode selected.
You can change the mode by using the Cruise Control
buttons. The two control modes function differently. Al-
ways confirm which mode is selected.
WARNING!
• Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibility
to be attentive of road, traffic, and weather condi-
tions, vehicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to ensure safe
operation of the vehicle under all road conditions.

STARTING AND OPERATING 293

WARNING!(Continued)
Your complete attention is always required while
driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a
collision and death or serious personal injury.
• The ACC system:
• Does not react to pedestrians, oncoming vehicles,
and stationary objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
• Cannot take street, traffic, and weather conditions
into account, and may be limited upon adverse
sight distance conditions.
• Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.
• Will bring the vehicle to a complete stop while
following a target vehicle and hold the vehicle for
2 seconds in the stop position. If the target vehicle
does not start moving within two seconds the ACC
system will display a message that the system will
release the brakes and that the brakes must be
applied manually. An audible chime will sound
when the brakes are released.
(Continued)
WARNING! (Continued)
You should switch off the ACC system:
•When driving in fog, heavy rain, heavy snow, sleet,
heavy traffic, and complex driving situations (i.e., in
highway construction zones).
• When entering a turn lane or highway off ramp;
when driving on roads that are winding, icy, snow-
covered, slippery, or have steep uphill or downhill
slopes.
• When towing a trailer up or down steep slopes.
• When circumstances do not allow safe driving at a
constant speed.
Adaptive Cruise Control (ACC) Operation
The Speed Control buttons (located on the right side of the
steering wheel) operates the ACC system.
