ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II. This
system monitors the performance of the
emissions, engine, and transmission control
systems. When these systems are operating
properly, your vehicle will provide excellent
performance and fuel economy, as well as engine
emissions well within current government
regulations.
If any of these systems require service, the OBD II
system will turn on the Malfunction Indicator Light
(MIL). It will also store diagnostic codes and other
information to assist your service technician in
making repairs. Although your vehicle will usually
be driveable and not need towing, see an
authorized dealer for service as soon as possible.
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have OBD II and a
connection port to allow access to information
related to the performance of your emissions
controls. Authorized service technicians may need
to access this information to assist with the
diagnosis and service of your vehicle and
emissions system Ú page 203.
CAUTION!
Prolonged driving with the MIL on could cause
further damage to the emission control
system. It could also affect fuel economy and
driveability. The vehicle must be serviced
before any emissions tests can be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.3

STARTING AND OPERATING147
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).
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 display will show the ACC Set With Target
Detected Indicator Light, and the system will adjust
the 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 144.
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
If the ACC system brings your vehicle to a standstill
while following a vehicle ahead, your vehicle will
resume motion, without any driver interaction, if
the vehicle ahead starts moving within two
seconds of your vehicle coming to a standstill.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:
If your vehicle is at a standstill for longer than
two seconds, the system will hold brake pres
-
sure for up to 10 minutes. If no driver action is
taken after the 10 minutes, the Electric Park
Brake will be applied and the ACC system will
cancel.
While ACC is holding your vehicle at a standstill
(or the vehicle is traveling below 3 mph
(5 km/h), and the driver seat belt is unbuckled
or the driver door is opened, the Electric Park
Brake will be applied and the ACC system will
cancel.
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.

23_WL_OM_EN_USC_t.book Page 147

STARTING AND OPERATING149
When the condition that created limited
functionality is no longer present, the system will
return to full functionality.
NOTE:If the “ACC Limited Functionality Clean Front Wind -
shield” 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.
SERVICE ACC WARNING
If the system turns off, and the instrument cluster
display reads “ACC Unavailable Service Required”
or “Cruise 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 increase or decrease the vehicle
speed for stability, with no vehicle ahead 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.

TRAFFIC SIGN ASSIST SYSTEM —
IF EQUIPPED
The Traffic Sign Assist (TSA) system uses a camera
mounted on the windshield, as well as map data
when the vehicle is equipped with Navigation, to
detect recognizable road signs such as:
Speed limits
School zones
No passing zones
NOTE:
The TSA system will automatically display the
detected road sign using the unit of measure-
ment (mph or km/h) selected within the instru -
ment cluster display.
If no speed limit signs are detected, the system
will revert to the speed limit signs that are
stored in the Navigation system.
The system always checks the traffic signs indi -
cating the current speed limit. The system is
able to recognize and display up to two different
road signs in the instrument cluster display.
These road signs can be found on the Driver
Assist page.
ACTIVATION/DEACTIVATION
The TSA System can be enabled/disabled within
the Uconnect system through the Safety/Driver
Assistance menu. System ON is signaled by road
signs shown on the instrument cluster display.

When Visual is selected, the system will alert the
driver when the current speed of the vehicle
exceeds the detected speed limit by showing a
graphic in the instrument cluster display. Visual + Chime
When Visual + Chime is selected, the system will
alert the driver when the current speed of the
vehicle exceeds the detected speed limit by
showing a graphic in the instrument cluster
display, and by sounding an audible alert. The
audible alert will last for 10 seconds, and the
visual alert will remain on as long as the vehicle is
exceeding the speed limit.
TSA Off
When the TSA system is turned off, the system will
not show any traffic signs (unless selected in the
HOME screen, which will show detected speed
limit signs), and no alerts will be issued to the
driver.
INDICATIONS ON THE DISPLAY
Detected traffic signs are shown in the instrument
cluster display, and can display any combination of
signs at one time (e.g. speed limit, speed limit and
supplemental info, and “Do Not Pass” signs)
depending on what information is available.
When a newly detected speed limit is higher than
the current speed limit, the display will update
along with an up arrow.

tall or greater in the upright position.
The detection distance for the system is between
26 ft (8 m) and 328 ft (100 m) from the front of the
vehicle.
The system may not be able to detect pedestrians
or animals in the following situations:
Pedestrian/animal is outside of the detection
range
Pedestrian/animal is fully or partially covered
Pedestrian/animal does not reach the minimum
detection height
NOTE:Other objects on the road that meet the height/
shape/temperature (e.g. sun exposure) of pedes -
trians/animals may be detected and classified as
targets.
WARNING!
Do not jerk the steering wheel in response to
a warning.
Never attempt to swerve around animals if
doing so would endanger you or others.
Do not stare at the image while driving. You
could crash and you or others could be
injured.
The Night Vision system only provides alerts to
objects of interest and cannot serve as a
substitute for the driver’s personal judgment.
The warnings are meant to direct your atten-
tion to the detected objects, but the Night
Vision system does not automatically brake
the vehicle and may not provide a warning
with enough time to help avoid a crash.
Warnings are only provided if a pedestrian or
large animal is detected by the system.
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 opera -
tion, to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle.
