STARTING AND OPERATING151
Activating Adaptive Cruise Control (ACC)
The minimum set speed for the ACC system is 
20 mph (32 km/h).
When the system is turned on and in the READY 
state, the instrument cluster displays “ACC Ready.”
When the system is off, the instrument cluster 
display “Adaptive Cruise Control (ACC) Off.”
NOTE:You cannot engage ACC under the following condi -
tions: 
When the brakes are applied
When the parking brake is applied
When the automatic transmission is in PARK, 
REVERSE or NEUTRAL
When the vehicle speed is below the minimum 
speed range
When the brakes are overheated
When the driver’s door is open at low speeds
When the driver’s seat belt is unbuckled at low 
speeds
To Activate/Deactivate
Push and release the Adaptive Cruise Control 
(ACC) on/off button. The ACC menu in the 
instrument cluster will read “ACC Ready.” To turn the system off, push and release the 
Adaptive Cruise Control (ACC) on/off button again. 
At this time, the system will turn off and the 
instrument cluster display will show “Adaptive 
Cruise Control (ACC) Off.”
To Set A Desired Speed
When the vehicle reaches the speed desired, push 
the SET 
(+) button or the SET  (-) button and 
release. The instrument cluster display will show 
the set speed.
NOTE:Fixed Speed Cruise Control can be used ACC 
enabled. To change between the different modes, 
push the ACC on/off button which turns the ACC 
and the Fixed Speed Cruise Control off. Pushing 
the Fixed Speed Cruise Control on/off button will 
result in turning on (changing to) Fixed Speed 
Cruise Control mode. If ACC is set when the vehicle speed is 
below 
20 mph (32 km/h), the set speed will default to 
20 mph (32 km/h).
NOTE:Fixed Speed Cruise Control cannot be set below 
20 mph (32 km/h).
If either system is set when the vehicle speed is 
above  20 mph (32 km/h), the set speed shall be 
the current speed of the vehicle.
NOTE:
Keeping your foot on the accelerator pedal can 
cause the vehicle to continue to accelerate 
beyond the set speed. If this occurs, the 
message “DRIVER OVERRIDE” will display in the 
instrument cluster display.
WARNING!
Leaving the Adaptive Cruise Control (ACC) 
system on when not in use is dangerous. You 
could accidentally set the system or cause it to 
go faster than you want. You could lose control 
and have a collision. Always leave the system off 
when you are not using it.
WARNING!
In the Fixed Speed Cruise Control mode, the 
system will not react to vehicles ahead. In 
addition, the proximity warning 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.

152STARTING AND OPERATING  
If you continue to accelerate beyond the set 
speed while ACC is enabled, the system will not 
be controlling the distance between your vehicle 
and the vehicle ahead. The vehicle speed will 
only be determined by the position of the accel-
erator pedal.
To Cancel
The following conditions cancel the ACC or Fixed 
Speed Cruise Control systems:
The brake pedal is applied
The CANC (cancel) button is pushed
The Anti-Lock Brake System (ABS) activates
The gear selector is removed from the DRIVE 
position
The Electronic Stability Control/Traction Control 
System (ESC/TCS) activates
The vehicle parking brake is applied
The braking temperature exceeds normal range 
(overheated).
The following conditions will only cancel the ACC 
system:
Driver seat belt is unbuckled at low speeds
Driver door is opened at low speeds
To Turn Off
The system will turn off and clear the set speed in 
memory if:
The Adaptive Cruise Control (ACC) on/off button 
is pushed
The Fixed Speed Cruise Control on/off button is 
pushed
The ignition is placed in the OFF position
To Resume
If there is a set speed in memory, push the RES 
(resume) button and then remove your foot from 
the accelerator pedal. The instrument cluster 
display will display the last set speed.
Resume can be used at any speed above 20 mph 
(32 km/h) when only Fixed Speed Cruise Control is 
being used.
NOTE:
If your vehicle is at a standstill longer than two 
seconds, the driver will either have to push the 
RES (resume) button, or apply the accelerator 
pedal to reengage the Adaptive Cruise Control 
(ACC) to the existing set speed.
ACC cannot be resumed if there is a stationary 
vehicle in front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set 
speed by pushing the SET  (+) button, or decrease 
speed by pushing the SET  (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will 
result in a 1 mph speed adjustment. Each 
subsequent tap of the button results in an 
adjustment of 1 mph.
If the button is continually pushed, the set 
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set 
speed is reflected in the instrument cluster 
display.
WARNING!
The Resume function should only be used if 
traffic and road conditions permit. Resuming a 
set speed that is too high or too low for 
prevailing traffic and road conditions could 
cause the vehicle to accelerate or decelerate too 
sharply for safe operation. Failure to follow these 
warnings can result in a collision and death or 
serious personal injury.
21_RUP_OM_EN_USC_t.book  Page 152   
Page 156 of 401

154STARTING AND OPERATING  
If there is no vehicle ahead, the vehicle will 
maintain the set speed. If a slower moving vehicle 
is detected in the same lane, the instrument 
cluster displays the ACC Set With Target Detected 
Indicator Light, and the system adjusts vehicle 
speed automatically to maintain the distance 
setting, regardless of the set speed.
The vehicle will then maintain the set distance 
until:
The vehicle ahead accelerates to a speed above 
the set speed.
The vehicle ahead moves out of your lane or 
view of the sensor.
The distance setting is changed.
The system disengages  Ú page 151.
The maximum braking applied by ACC is limited; 
however, the driver can always apply the brakes 
manually, if necessary.
NOTE:The brake lights will illuminate whenever the ACC 
system applies the brakes.
A Proximity Warning will alert the driver if ACC 
predicts that its maximum braking level is not 
sufficient to maintain the set distance. If this 
occurs, a visual alert “BRAKE!” will flash in the 
instrument cluster display and a chime will sound 
while ACC continues to apply its maximum braking 
capacity.
NOTE:The “BRAKE!” screen in the instrument cluster 
display is a warning for the driver to take action 
and does not necessarily mean that the Forward 
Collision Warning system is applying the brakes 
autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC) 
engaged and following a vehicle, the system will 
provide an additional acceleration up to the ACC 
set speed to assist in passing the vehicle. This 
additional acceleration is triggered when the driver 
utilizes the left turn signal and will only be active 
when passing on the left hand side.
ACC Operation At Stop
In the event that the ACC system brings your 
vehicle to a standstill while following the vehicle in 
front, your vehicle will resume motion, without the 
need for any driver action, if the vehicle in front 
starts moving within two seconds.
If the vehicle in front does not start moving within 
two seconds of your vehicle coming to a standstill, 
the driver will either have to push the RES (resume) 
button, or apply the accelerator pedal to reengage 
the ACC to the existing set speed.
NOTE:After the ACC system holds your vehicle at a stand -
still for approximately three consecutive minutes, 
the parking brake will be activated, and the ACC 
system will be cancelled.
While the ACC system is holding your vehicle at a 
standstill, if the driver seat belt is unbuckled or the 
driver door is opened, the parking brake will be 
activated, and the ACC system will be cancelled.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR” WARNING
The “ACC/AEB Unavailable Wipe Front Radar 
Sensor” warning will display and a chime will 
sound when conditions temporarily limit system 
performance.
WARNING!
When the ACC system is resumed, the driver 
must ensure that there are no pedestrians, 
vehicles or objects in the path of the vehicle. 
Failure to follow these warnings can result in a 
collision and death or serious personal injury.
21_RUP_OM_EN_USC_t.book  Page 154   
Page 157 of 401

STARTING AND OPERATING155
This most often occurs at times of poor visibility, 
such as in snow or heavy rain. The ACC system may 
also become temporarily blinded due to 
obstructions, such as mud, dirt or ice. In these 
cases, the instrument cluster display will show 
“ACC/AEB Unavailable Wipe Front Radar Sensor” 
and the system will deactivate.
The “ACC/AEB Unavailable Wipe Front Radar 
Sensor” message can sometimes be displayed 
while driving in highly reflective areas (i.e. ice and 
snow, or tunnels with reflective tiles). The ACC 
system will recover after the vehicle has left these 
areas. Under rare conditions, when the radar is not 
tracking any vehicles or objects in its path this 
warning may temporarily occur.
NOTE:If the “ACC/AEB Unavailable Wipe Front Radar 
Sensor” warning is active, Fixed Speed Cruise 
Control is still available.
If weather conditions are not a factor, the driver 
should examine the sensor. It may require cleaning 
or removal of an obstruction. The sensor is located 
in the center of the vehicle behind the lower grille.
To keep the ACC System operating properly, it is 
important to note the following maintenance 
items:
Always keep the sensor clean. Carefully wipe the 
sensor lens with a soft cloth. Be cautious not to 
damage the sensor lens.
Do not remove any screws from the sensor. 
Doing so could cause an ACC system malfunc -
tion or failure and require a sensor realignment.
If the sensor or front end of the vehicle is 
damaged due to a collision, see an authorized 
dealer for service.
Do not attach or install any accessories near the 
sensor, including transparent material or after -
market 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/AEB Unavailable Wipe Front Radar 
Sensor” message occurs frequently (e.g. more 
than once on every trip) without any snow, rain, 
mud, or other obstruction, have the radar sensor 
realigned at an authorized dealer.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/AEB Limited Functionality Clean Front 
Windshield” warning will display and a chime will 
sound when conditions temporarily limit system 
performance. This most often occurs at times of 
poor visibility, such as in snow or heavy rain and 
fog. The ACC system may also become temporarily  blinded due to obstructions, such as mud, dirt, or 
ice on windshield, driving directly into the sun and 
fog on the inside of glass. In these cases, the 
instrument cluster display will show “ACC/AEB 
Limited Functionality Clean Front Windshield” and 
the system will have degraded performance.
The “ACC/AEB Limited Functionality Clean Front 
Windshield” 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 rearview 
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/AEB 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 an authorized 
dealer.

156STARTING AND OPERATING  
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster 
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 
functionality. Although the vehicle is still drivable 
under normal conditions, ACC will be temporarily 
unavailable. If this occurs, try activating ACC again 
later, following an ignition cycle. If the problem 
persists, see an 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. The following are 
examples of these types of situations:
TOWING A TRAILER
Towing a trailer is not recommended 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 vehicle in 
front 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. 
The driver must maintain control of the vehicle, 
remain alert, and be ready to apply the brakes if 
needed.
 Turn Or Bend Example
21_RUP_OM_EN_USC_t.book  Page 156   
Page 186 of 401

184STARTING AND OPERATING  
The electrical connections are all complete to the 
vehicle but you must mate the harness to a trailer 
connector. Refer to the following illustrations.
NOTE:
Disconnect trailer wiring connector from the 
vehicle before launching a boat (or any other 
device plugged into vehicle’s electrical connect) 
into water.
Be sure to reconnect once clear from water 
area.
Four-Pin Connector Seven-Pin Connector
TOWING TIPS 
Before towing, practice turning, stopping, and 
backing up the trailer in an area located away from 
heavy traffic.
Automatic Transmission
Select the DRIVE range when towing. The 
transmission controls include a drive strategy to 
avoid frequent shifting when towing. For increased 
engine braking on steep downhill grades, select 
the LOW range.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience 
speed drops greater than 10 mph (16 km/h), 
disengage until you can get back to cruising 
speed.
Use Cruise Control in flat terrain and with light 
loads to maximize fuel efficiency.

246SAFETY  
FCW Limited Warning
If the instrument cluster displays “ACC/FCW 
Limited Functionality” or “ACC/FCW Limited 
Functionality Clean Front Windshield” 
momentarily, there may be a condition that limits 
FCW functionality. Although the vehicle is still 
drivable under normal conditions, the active 
braking may not be fully available. Once the 
condition that limited the system performance is 
no longer present, the system will return to its full 
performance state. If the problem persists, see an 
authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster 
displays:
ACC/FCW Unavailable Service Required
Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. 
Although the vehicle is still drivable under normal 
conditions, have the system checked by an 
authorized dealer.
Pedestrian Emergency Braking (PEB) — If 
Equipped
The Pedestrian Emergency Braking (PEB) is a 
subsystem of the FCW system which provides the 
driver with audible and visual warnings in the 
instrument cluster display, and may apply 
automatic braking when it detects a potential 
frontal collision with a pedestrian.
If a PEB event begins at a speed below 37 mph 
(60 km/h), the system may provide braking to 
mitigate the potential collision with a pedestrian. If 
the PEB event stops the vehicle completely, the 
system will hold the vehicle at a standstill for two 
seconds and then release the brakes. When the 
system determines a collision with the pedestrian 
in front of you is no longer probable, the warning 
message will be deactivated.
The minimum speed for PEB activation is 3 mph 
(5 km/h). Turning PEB On Or Off
NOTE:The default status of PEB is “On.” This allows the 
system to warn you of a possible frontal collision 
with the pedestrian.
The PEB button is located in the Uconnect display 
in the Controls settings  Ú
page 189.
To turn the PEB system off, push the Pedestrian 
Emergency Braking OFF button.
To turn the PEB system back on, push the Warning 
Active Braking button.
Changing the PEB status to “Off” deactivates the 
system, so no warning or active braking will be 
available in case of a possible frontal collision with 
the pedestrian.
NOTE:The PEB system will NOT retain the last setting 
selected by the driver after ignition shut down. The 
system will reset to the default setting when the 
vehicle is restarted.
WARNING!
Pedestrian Emergency Braking (PEB) is not 
intended to avoid a collision on its own, nor can 
PEB detect every type of potential collision with 
a pedestrian. The driver has the responsibility to 
avoid a collision by controlling the vehicle via 
braking and steering. Failure to follow this 
warning could lead to serious injury or death.
