conditions (city driving, towing, frequent stop-
ping).

Installing options like additional lights, upfitter
electrical accessories, audio systems, alarms
and similar devices.
Unusual driving cycles (short trips separated by
long parking periods).
The vehicle was parked for an extended period
of time (weeks, months).
The battery was recently replaced and was not
charged completely.
The battery was discharged by an electrical load
left on when the vehicle was parked.
The battery was used for an extended period
with the engine not running to supply radio,
lights, chargers, +12 Volts portable appliances
like vacuum cleaners, game consoles and
similar devices. What to do when an electrical load reduction
action message is present (“Battery Saver On” or
“Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if possible:

Turn off redundant lights (interior or exterior)

Check what may be plugged in to power
outlets +12 Volts, 115 Volts AC, USB ports
Check HVAC settings (blower, temperature)
Check the audio settings (volume)
After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, alarms) and review
specifications if any (load and Ignition Off Draw
currents).
Evaluate the latest driving cycles (distance,
driving time and parking time).
The vehicle should have service performed if
the message is still present during consecutive
trips and the evaluation of the vehicle and
driving pattern did not help to identify the cause.
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated
message and/or acoustic signal when applicable.
These indications are indicative and precautionary
and as such must not be considered as exhaustive
and/or alternative to the information contained in
the Owner’s Manual, which you are advised to read
carefully in all cases. Always refer to the
information in this chapter in the event of a failure

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 drivable 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 119.
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.

21_LA_OM_EN_USC_t.book Page 76

100STARTING AND OPERATING
To increase the distance setting, push the
Distance Setting 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 Setting 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 Adaptive Cruise
Control (ACC) Set With Target Vehicle 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 97.
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 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.
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.

Safety/Assistance
When the Safety/Assistance button is selected on the touchscreen, the system displays the options related to the vehicle’s safety settings. These options will
differ depending on the features equipped on the vehicle. The settings may display in list form or within subfolders on the screen. To access a subfolder, select
the desired folder; the available options related to that feature will then display on the screen.
NOTE:Depending on the vehicle’s options, feature settings may vary.
Setting Name Description
Forward Collision Warning SensitivityThis setting will change the distance at which the Forward Collision Warning
(FCW) alert sounds. The “Medium” setting will have the FCW system signal when an object is in view, and the possibility of a collision is detected. The
“Near” setting will have the FCW system signal when the object is closer to the
vehicle. The “Far” setting will have the FCW system signal when an object is at a far distance from the vehicle.
Forward Collision Warning
This setting will turn the Forward Collision Warning system on or off. The “Off” setting
will deactivate the FCW system. The “Warning Only” setting will provide only an
audible chime when a collision is detected. The “Warning + Active Braking” setting
will provide an audible chime and apply brake pressure when a collision is detected.

ParkSense This setting will change the type of ParkSense alert when a close object is
detected and provide both an audible chime and a visual display.
Rear ParkSense Volume This setting adjusts the volume of the Rear ParkSense system. The available
settings are “Low”, “Medium”, and “High”.
Blind Spot Alert This setting will change the type of alert provided when an object is detected
in a vehicle’s blind spot. The “Off” setting will turn off Blind Spot Alert. The
“Lights” setting will activate the Blind Spot Alert lights on the outside mirrors. The “Lights & Chime” setting will activate both the lights on the outside mirrors and an audible chime.5

SAFETY187
Modes Of Operation
Blind Spot has three selectable modes of
operation that are available in the Uconnect
system.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the BSM
system will provide a visual alert in the appropriate
side view mirror based on a detected object.
However, when the system is operating in RCP
mode, the system will respond with both visual and
audible alerts when a detected object is present.
Whenever an audible alert is requested, the radio
volume is reduced so that the alert can be better
heard. Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime
mode, the BSM system will provide a visual alert in
the appropriate side view mirror based on a
detected object. If the turn signal is then activated,
and it corresponds to an alert present on that side
of the vehicle, an audible chime will also be
sounded. Whenever a turn signal and detected
object are present on the same side at the same
time, both the visual and audio alerts will be
issued. In addition to the audible alert the radio (if
on) volume will be reduced so that the alert can be
better heard.
When the system is in RCP, the system shall
respond with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio volume is reduced so
that the alert can be better heard.
Blind Spot Alert Off
When the BSM system is turned off there will be no
visual or audible alerts from either the BSM or RCP
systems.
NOTE:The BSM system will store the current operating
mode when the vehicle is shut off. Each time the
vehicle is started the previously stored mode will
be recalled and used.
FORWARD COLLISION WARNING (FCW)
O
PERATION — IF EQUIPPED
FCW with Mitigation provides the driver with
audible warnings and visual warnings (within the
instrument cluster display) to warn the driver when
it detects a potential frontal collision. The warnings
are intended to provide the driver with enough time
to react, avoid or mitigate the potential collision.
NOTE:FCW monitors the information from the forward
looking sensors as well as the Electronic Stability
Control (ESC) system, to calculate the probability of
a forward collision. When the system determines
that a forward collision is probable, the driver will
be provided with audible and visual warnings.

FCW Message

WARNING!
Rear Cross Path Detection (RCP) is not a backup
aid system. It is intended to be used to help a
driver detect an oncoming vehicle in a parking
lot situation. Drivers must be careful when
backing up, even when using RCP. Always check
carefully behind your vehicle, look behind you,
and be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind spots
before backing up. Failure to do so can result in
serious injury or death.

SAFETY203
The steering wheel hub trim cover and the upper
passenger side of the instrument panel separate
and fold out of the way as the air bags inflate to
their full size. The front air bags fully inflate in less
time than it takes to blink your eyes. The front air
bags then quickly deflate while helping to restrain
the driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees
of the driver and front passenger, and position the
front occupants for improved interaction with the
front air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags (SABs)
This vehicle is equipped with Supplemental
Seat-Mounted Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags (SABs)
are located in the outboard side of the front seats.
The SABs are marked with “SRS AIRBAG” or
“AIRBAG” on a label or on the seat trim on the
outboard side of the seats.
The SABs may help to reduce the risk of occupant
injury during certain side impacts, in addition to
the injury reduction potential provided by the seat
belts and body structure.

Front Supplemental Seat-Mounted Side Air Bag Label
When the SAB deploys, it opens the seam on the
outboard side of the seatback’s trim cover. The
inflating SAB deploys through the seat seam into
the space between the occupant and the door. The
SAB moves at a very high speed and with such a
high force that it could injure occupants if they are
not seated properly, or if items are positioned in
the area where the SAB inflates. Children are at an
even greater risk of injury from a deploying air bag.
WARNING!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the knee
impact bolsters such as alarm lights, stereos,
citizen band radios, etc.
WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air Bags; the
performance could be adversely affected and/or
objects could be pushed into you, causing
serious injury.
