90STARTING AND OPERATING
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
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. 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
display “ACC/FCW Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). 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/FCW 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 malfunction 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 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 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.
 Installing a snow plow, front-end protector, an after -
market grille or modifying the grille is not recom -
mended. Doing so may block the sensor and inhibit
ACC/FCW operation.
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.

23_LA_OM_EN_USC_t.book Page 90

92STARTING AND OPERATING
STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects or 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. It will consider this stopped vehicle a
stationary object as it did not previously detect movement
from it. Always be attentive and ready to apply the brakes
if necessary.

Stationary Object And Stationary Vehicle Example

PARKSENSE REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Rear Park Assist system provides visual
and audible indications of the distance between the rear
fascia/bumper and a detected obstacle when backing up
(e.g. during a parking maneuver).
For limitations of this system and recommendations,
see
Úpage 95.
ParkSense will retain the last system state (enabled or
disabled) from the previous ignition cycle when the
ignition is changed to the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE. If ParkSense is enabled at this gear selector
position, the system will remain active until the vehicle
speed is increased to approximately 7 mph (11 km/h) or
above. The system will become active again if the vehicle
speed is decreased to speeds less than approximately
6 mph (9 km/h).
PARKSENSE SENSORS
The four ParkSense sensors, located in the rear
fascia/bumper, monitor the area behind the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/bumper in the
horizontal direction, depending on the location, type and
orientation of the obstacle.
PARKSENSE DISPLAY
When the vehicle is in REVERSE, the warning display will
turn on indicating the system status.
The system will indicate a detected obstacle by showing a
single arc in one or more regions based on the obstacle’s
distance and location relative to the vehicle.
If an obstacle is detected in the center rear region, the
display will show a single solid arc in the center rear region
and will produce a one-half second tone. As the vehicle
moves closer to the obstacle, the display will show the
single arc moving closer to the vehicle and the sound tone
will change from slow, to fast, to continuous.
If an obstacle is detected in the left and/or right rear
region, the display will show a single flashing arc in the left
and/or right rear region and will produce a fast sound
tone. As the vehicle moves closer to the obstacle, the
display will show the single arc moving closer to the
vehicle and the sound tone will change from fast to
continuous.

23_LA_OM_EN_USC_t.book Page 92

94STARTING AND OPERATING
The vehicle is close to the obstacle when the warning display shows one flashing arc and sounds a continuous tone. The following chart shows the warning alert operation when the
system is detecting an obstacle:
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen will only be displayed if
Sound and Display is selected from within the Uconnect
system
Úpage 107.
The ParkSense Warning screen is located within the
instrument cluster display. It provides visual warnings to
indicate the distance between the rear fascia/bumper
and the detected obstacle.
ENABLING AND DISABLING PARKSENSE
ParkSense can be enabled and disabled with
the ParkSense switch, located on the switch
panel below the Uconnect display. When the ParkSense switch is pushed to disable the
system, the instrument cluster will display the “ParkSense
Off” message for approximately five seconds. When the
gear selector is moved to REVERSE and the system is
disabled, the instrument cluster display will display the
“ParkSense Off” message for as long as the vehicle is in
REVERSE.
The ParkSense switch LED will be on when ParkSense is
disabled or requires service. The ParkSense switch LED
will be off when the system is enabled. If the ParkSense
switch is pushed, and the system requires service, the
ParkSense switch LED will blink momentarily, and then the
LED will be on.
SERVICE THE PARKSENSE REAR PARK
A
SSIST SYSTEM
During vehicle start up, when the ParkSense Rear Park
Assist System has detected a faulted condition, the
instrument cluster will actuate a single chime, once per
ignition cycle and it will display the “PARKSENSE
UNAVAILABLE WIPE REAR SENSORS” or “PARKSENSE
UNAVAILABLE SERVICE REQUIRED” message for five
seconds.

STARTING AND OPERATING95
When the gear selector is moved to REVERSE and the
system has detected a faulted condition, the instrument
cluster display will display the “PARKSENSE UNAVAILABLE
WIPE REAR SENSORS” or “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message for as long as the vehicle is
in REVERSE. Under this condition, ParkSense will not
operate.
If “PARKSENSE UNAVAILABLE WIPE REAR SENSORS”
appears in the instrument cluster display, make sure the
outer surface and the inside of the rear fascia/bumper is
clean and clear of snow, ice, mud, dirt or other
obstruction, and then cycle the ignition. If the message
continues to appear see an authorized dealer.
If “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
appears in the instrument cluster display, see an
authorized dealer.
CLEANING THE PARKSENSE SYSTEM
Clean the Rear Park Assist sensors with water, car wash
soap and a soft cloth. Do not use rough or hard cloths. In
washing stations, clean sensors quickly keeping the vapor
jet/high pressure washing nozzles at least 4 inches (10
cm) from the sensors. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
 Ensure that the rear fascia/bumper is free of snow, ice,
mud, dirt and debris to keep the ParkSense system
operating properly.
 Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense or render the
system temporarily unavailable.
 When you turn ParkSense off in DRIVE, the instrument
cluster will display "PARKSENSE OFF" for five seconds.
Furthermore, once you turn ParkSense off, it remains
off until you turn it on again, even if you cycle the igni -
tion.
 When you move the gear selector to the REVERSE posi -
tion and ParkSense is turned off, the instrument
cluster display will show the “PARKSENSE OFF”
message for as long as the vehicle is in REVERSE.
 ParkSense will reduce the volume of the radio when it
is sounding an audio tone.
 Clean the ParkSense sensors regularly, taking care not
to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind the fascia/bumper, or it could provide
a false indication that an obstacle is behind the fascia/
bumper. 
Ensure the ParkSense system is off if objects such as
bicycle carriers, trailer hitches, etc., are placed within
12 inches (30 cm) from the rear fascia/bumper.
Failure to do so can result in the system misinter -
preting a close object as a sensor problem, causing the
“PARKSENSE UNAVAILABLE SERVICE REQUIRED”
message to be shown in the instrument cluster display.
WARNING!
Drivers must be careful when backing up even when
using the Rear Park Assist system. Always check
carefully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible for
the safety of your surroundings and must continue to
pay attention while backing up. Failure to do so can
result in serious injury or death.
CAUTION!
 ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
 The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time when an
obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using
ParkSense.

 Steering Wheel Angle
Steering Wheel Angle utilizes the steering angle sensor
to measure the degree of the steering wheel relative to
zero (straight ahead) reference angle. The zero degree
reference angle measurement indicates a steering
wheel straight ahead position.
The friction circle display shows instantaneous G-Force as
a highlight and previous G-Force as dots within the circle.
The system records previous G-Force for three minutes. If
there are multiple samples at a given point, the color of
the dot will darken from blue to red. Vectors more frequent
will show in red; infrequent vectors will show in blue.

SAFETY161
Electronic Stability Control (ESC)
ESC enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying
the brake of the appropriate wheel(s) to counteract the
previously mentioned conditions. Engine power may also
be reduced to help the vehicle maintain the desired path.
Oversteer — when the vehicle is turning more than
appropriate for the steering wheel position.
 Understeer — when the vehicle is turning less than
appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the oversteer
or understeer condition.
The ESC Activation/Malfunction Indicator Light located in
the instrument cluster will start to flash as soon as the ESC
system becomes active. The ESC Activation/Malfunction
Indicator Light also flashes when the TCS is active. If the
ESC Activation/Malfunction Indicator Light begins to flash
during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
ESC Operating Modes
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes stuck.
This mode may modify TCS and ESC thresholds for
activation, which allows for more wheel spin than normally
allowed.
To enter the “Partial Off” mode, momentarily push the ESC
OFF button and the ESC OFF Indicator Light will illuminate.
To turn the ESC on again, momentarily push the ESC OFF
button and the ESC OFF Indicator Light will turn off.WARNING!
 Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro -
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capabil -
ities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of
others.
 Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris -
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.
WARNING!
When in “Partial Off” mode, the TCS functionality of ESC
(except for the limited slip feature described in the TCS
section) has been disabled and the ESC OFF Indicator
Light will be illuminated. When in “Partial Off” mode,
the engine power reduction feature of TCS is disabled,
and the enhanced vehicle stability offered by the ESC
system is reduced.

AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM) —
I
F EQUIPPED
BSM uses two radar sensors, located inside the rear
fascia/bumper, to detect highway licensable vehicles
(automobiles, trucks, motorcycles, etc.) that enter the
blind spot zones from the rear/front/side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light will
momentarily illuminate in both outside rearview mirrors to
let the driver know that the system is operational. Automatic Transmission Vehicles
The BSM system sensors operate when the vehicle is in
any forward gear or NEUTRAL.
Manual Transmission Vehicles
The BSM system sensors operate when the vehicle is in
any gear selector position, except REVERSE.

BSM Warning Light

The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the outside rearview mirror and extends
approximately 10 ft (3 m) beyond the rear fascia/bumper
of the vehicle. The BSM system monitors the detection
zones on both sides of the vehicle when the vehicle speed
reaches approximately 6 mph (10 km/h) or higher and will
alert the driver of vehicles in these areas.
NOTE:

The BSM system DOES NOT alert the driver about
rapidly approaching vehicles that are outside the
detection zones.
 The BSM system detection zone DOES NOT change if
your vehicle is towing a trailer. Therefore, visually verify
the adjacent lane is clear for both your vehicle and
trailer before making a lane change. If the trailer or
other object (i.e., bicycle, sports equipment) extends
beyond the side of your vehicle, this may result in the
BSM Warning Light remaining illuminated the entire
time the vehicle is in a forward gear.
 The BSM system may experience dropouts (blinking on
and off) of the side mirror warning indicator lamps
when a motorcycle or any small object remains at the
side of the vehicle for extended periods of time (more
than a couple of seconds).
The area on the rear fascia/bumper where the radar
sensors are located must remain free of snow, ice and
dirt/road contamination so that the BSM system can
function properly. Do not block the area of the rear fascia/
bumper where the radar sensors are located with foreign
objects (bumper stickers, bicycle racks, etc.).

23_LA_OM_EN_USC_t.book Page 164

SAFETY165
The BSM system can become blocked if snow, ice, mud, or
other road contaminations accumulate on the rear fascia/
bumper where the radar sensors are located. The system
may also detect blockage if the vehicle is operated in
areas with extremely low radar returns such as a desert or
parallel to a large elevation drop. If a blockage is detected,
a “Blind Spot Temporarily Unavailable, Wipe Rear
Corners” message will display in the cluster, both mirror
lights will illuminate, and BSM and RCP alerts will not
occur. This is normal operation. The system will
automatically recover and resume function when the
condition clears. To minimize system blockage, do not
block the area of the rear fascia/bumper where the radar
sensors are located with foreign objects (bumper stickers,
bicycle racks, etc.) and keep it clear of road
contaminations.

Sensor Location

The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM Warning Light
located in the outside mirrors in addition to sounding an
audible (chime) alert and reducing the radio volume
Úpage 167.
The BSM system monitors the detection zone from three
different entry points (side, rear, front) while driving to see
if an alert is necessary. The BSM system will issue an alert
during these types of zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes from either
side of the vehicle.

Side Monitoring

Entering From The Rear
Vehicles that come up from behind your vehicle on either
side and enter the rear detection zone with a relative
speed of less than 31 mph (50 km/h).

Rear Monitoring

Overtaking Traffic
If you pass another vehicle slowly (with a relative speed of
less than 15 mph (24 km/h)), the warning light will be illuminated. If the difference in speed between the two
vehicles is greater than 15 mph (24 km/h), the warning light will not illuminate.
