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 tap on the brake pedal, or pushing the CANC 
button, or normal brake pressure will deactivate 
the Cruise Control system without erasing the set 
speed from memory.
Pushing the on/off button or placing the ignition in 
the OFF position erases the set speed from 
memory.
ADAPTIVE CRUISE CONTROL (ACC)  
Adaptive Cruise Control (ACC) increases the driving 
convenience provided by cruise control while 
traveling on highways and major roadways. 
However, it is not a safety system and not designed 
to prevent collisions. The Cruise Control function 
performs differently   Úpage 147.
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 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.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance 
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled) 
will not detect vehicles directly ahead of you. 
Always be aware of the feature selected  
Ú page 387.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active 
driver involvement. It is always the driver’s 
responsibility to be attentive of road, traffic, 
and weather conditions, vehicle speed, 
distance to the vehicle ahead and, most 
importantly, brake operation to ensure safe 
operation of the vehicle under all road condi -
tions. Your complete attention is always 
required while driving to maintain safe control 
of your vehicle. Failure to follow these warn -
ings 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 condi -
tions.
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 approximately three 
minutes in the stop position. If the target 
vehicle does not start moving within three 
minutes the parking brake will be acti -
vated, and the ACC system will be 
cancelled.

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 155 of 401

STARTING AND OPERATING153
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will 
result in a 1 km/h speed adjustment. Each 
subsequent tap of the button results in an 
adjustment of 1 km/h.
If the button is continually pushed, the set 
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set 
speed is reflected in the instrument cluster 
display.
NOTE:When you override and push the SET (+)  button or 
SET  (-) buttons, the new set speed will be the 
current speed of the vehicle.
When An ACC Is Active:
When you use the SET  (-) button to decelerate, if 
the engine’s braking power does not slow the 
vehicle sufficiently to reach the set speed, the 
brake system will automatically slow the 
vehicle.
The ACC system decelerates the vehicle to a full 
stop when following the vehicle in front. If your 
vehicle follows the vehicle in front to a standstill, 
after two seconds 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.
The ACC system maintains set speed when 
driving uphill and downhill. However, a slight 
speed change on moderate hills is normal. In 
addition, downshifting may occur while climbing 
uphill or descending downhill. This is normal 
operation and necessary to maintain set speed. 
When driving uphill and downhill, the ACC 
system will cancel if the braking temperature 
exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set 
by varying the distance setting between four bars 
(longest), three bars (long), two bars (medium) and 
one bar (short). Using this distance setting and the 
vehicle speed, ACC calculates and sets the 
distance to the vehicle ahead. This distance 
setting displays in the instrument cluster display.
 Distance Settings
To increase the distance setting, push the 
Distance Increase button and release. Each time 
the button is pushed, the distance setting 
increases by one bar (longer).
To decrease the distance setting, push the 
Distance Decrease button and release. Each time 
the button is pushed, the distance setting 
decreases by one bar (shorter). 1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)

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 159 of 401

STARTING AND OPERATING157
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 performance may be limited.
NOTE:The driver must maintain control of the vehicle, 
remain alert, and be ready to apply the brakes if 
needed.
ACC Hill Example
LANE CHANGING
ACC may not detect a vehicle until it is completely 
in the lane in which you are traveling. In the lane 
changing example below, 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.
Lane Changing Example
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.
Narrow Vehicle Example

21_RUP_OM_EN_USC_t.book  Page 157   
Page 160 of 401

158STARTING AND OPERATING  
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.
Stationary Object And Stationary Vehicle Example
PARKSENSE FRONT/REAR PARK ASSIST 
SYSTEM — IF EQUIPPED 
The ParkSense Park Assist system provides visual 
and audible indications of the distance between 
the rear, and if equipped, the front fascia/bumper 
and a detected obstacle when backing up or 
moving forward (e.g. during a parking maneuver). 
The vehicle brakes may be automatically applied 
and released when performing a reverse parking 
maneuver if the system detects a possible collision 
with an obstacle.
NOTE:
The driver can override the automatic braking 
function by pressing the gas pedal over 90% of 
its capacity during the braking event, turning 
ParkSense off via the ParkSense switch, or 
changing the gear while the automatic brakes 
are being applied.
Automatic brakes will not be available if ESC is 
not available.
Automatic brakes will not be available if there is 
a faulted condition detected with the ParkSense 
Park Assist system or the Braking System 
Module.
The automatic braking function may not provide 
enough vehicle deceleration to avoid colliding 
with a detected obstacle depending on vehicle 
speed, road conditions, and brake capability.
The automatic braking function may not be 
applied fast enough for moving obstacles that 
approach the rear of the vehicle from the left 
and/or right sides.
The automatic braking function can be 
enabled/disabled from the Customer-Program -
mable Features section of the Uconnect system.
ParkSense will retain its last known configura -
tion state for the automatic braking function 
through ignition cycles.
The automatic braking function is intended to 
assist the driver in avoiding possible collisions with 
detected obstacles when backing up in REVERSE 
gear.
