WARNING LIGHTS AND
MESSAGES
The warning/indicator lights will illuminate in
the instrument panel together with a dedi-
cated 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 care-
fully in all cases. Always refer to the informa-
tion in this chapter in the event of a failure
indication. All active telltales will display first
if applicable. The system check menu may
appear different based upon equipment op-
tions and current vehicle status. Some tell-
tales are optional and may not appear.
Red Warning Lights
— Seat Belt Reminder Warning Light
This light indicates when the driver or pas-
senger seat belt is unbuckled. When the
ignition is first placed in the ON/RUN or
ACC/ON/RUN position and if the driver’s seat
belt is unbuckled, a chime will sound and thelight will turn on. When driving, if the driver
or front passenger seat belt remains unbuck-
led, the Seat Belt Reminder Light will flash or
remain on continuously and a chime will
sound. Refer to “Occupant Restraint Sys-
tems” in “Safety” for further information.
— Air Bag Warning Light
This light indicates a fault with the air bag,
and will turn on for four to eight seconds as a
bulb check when the ignition is placed in the
ON/RUN or ACC/ON/RUN position. This light
will illuminate with a single chime when a
fault with the air bag has been detected, it
will stay on until the fault is cleared. If the
light is either not on during startup, stays on,
or turns on while driving, have the system
inspected at an authorized dealer as soon as
possible.
— Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied,
that the brake fluid level is low, or that there
is a problem with the anti-lock brake system.
If the light remains on when the parking
brake has been disengaged, and the fluid
level is at the full mark on the master cylinder
reservoir, it indicates a possible brake hy-
draulic system malfunction or that a problem
with the Brake Booster has been detected by
the Anti-Lock Brake System (ABS) / Elec-
tronic Stability Control (ESC) system. In this
case, the light will remain on until the condi-
tion has been corrected. If the problem is
related to the brake booster, the ABS pump
will run when applying the brake, and a brake
pedal pulsation may be felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in
either half of the dual brake system is indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied level.
The light will remain on until the cause is
corrected.

Yellow Warning Lights
— Engine Check/Malfunction Indica-
tor Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine
and automatic transmission control systems.
This warning light will illuminate when the
ignition is in the ON/RUN position before
engine start. If the bulb does not come on
when turning the ignition switch from OFF to
ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.
When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe
catalytic converter damage. The vehicle
should be serviced as soon as possible if this
occurs.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the vehicle control system. It also

When the vehicle is started, the BSM warning
light will momentarily illuminate in both out-
side rear view mirrors to let the driver know
that the system is operational. The BSM
system sensors operate when the vehicle is in
any forward gear or REVERSE and enters
stand by mode when the vehicle is in PARK.
The BSM warning light, located in the out-
side mirrors, will illuminate if a vehicle
moves into a blind spot zone.The BSM system can also be configured to
sound an audible (chime) alert and mute the
radio to notify you of objects that have en-
tered the detection zones.
Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is in-
tended to aid the driver when backing out of
parking spaces where the vision of oncoming
vehicles may be blocked. Proceed slowly and
cautiously out of the parking space until the
rear end of the vehicle is exposed. The RCP
system will then have a clear view of the cross traffic and if an oncoming vehicle is de-
tected, will alert the driver. When RCP is on
and the vehicle is in REVERSE, the driver is
alerted using both the visual and audible
alarms, including reducing the radio volume.
Refer to “Blind Spot Monitoring” in “Safety”
in the Owner's Manual for further informa-
tion.
Modes Of Operation
Three selectable modes of operation are
available in the Uconnect System. Refer to
“Uconnect Settings” in “Multimedia” in the
Owner's Manual for further details.
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 de-
tected object. However, when the system is
operating in Rear Cross Path (RCP) mode, the
system will respond with both visual and
audible alerts when a detected object is pres-
ent. Whenever an audible alert is requested,
the radio is muted.Rear Detection ZonesBSM Warning Light

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. When-
ever a turn signal and detected object are
present on the same side at the same time,
both the visual and audible alerts will be
issued. In addition to the audible alert, the
radio (if on) will also be muted.
NOTE:
Whenever an audible alert is requested by the
BSM system, the radio is also muted.
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 is also
muted. Turn/hazard signal status is ignored;
the RCP state always requests the chime.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 oper-
ating 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)
The Forward Collision Warning (FCW) system
provides the driver with audible 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 for-
ward looking sensors, as well as the Elec-
tronic Brake Controller (EBC), to calculate
the probability of a forward collision. When
the system determines that a forward colli-
sion is probable, the driver will be provided
with audible and visual warnings.Turning FCW On Or Off
The FCW button is located on the switch
panel below the Uconnect display.
• To turn the FCW system off, push the for-
ward collision button once to turn the sys-
tem OFF.
• To turn the FCW system back on, push the forward collision button again to turn the
system on.
NOTE:
• The default status of FCW is “on”, this allows the system to warn you of a possible
collision with the vehicle in front of you.
• Changing the FCW status to “off” prevents the system from warning you of a possible
collision with the vehicle in front of you. If
FCW is set to off, “FCW OFF” will appear in
the instrument cluster display.
Changing FCW Status
The FCW feature has two settings and can be
changed within the Uconnect System
