allel to the rack frame. Once the crossbar is in
the desired position, retighten the with the
wrench to lock the crossbar into position.
NOTE:
• To help control wind noise when the cross-
bars are not in use, place the front and rear
crossbars approximately 24 inches (61 cm)
apart. Optimal noise reduction can then be
achieved by adjusting the front crossbar
forward or aft using increments of 1 inch
(2.5 cm).
• If any cargo (or any metallic object) is
placed over the satellite radio antenna (if
equipped), you may experience interrup-
tion of satellite radio reception. For im-
proved satellite radio reception, avoid plac-
ing the rear crossbar over the satellite radio
antenna.
WARNING!
Cargo must be securely tied down before
driving your vehicle. Improperly secured
loads can fly off the vehicle, particularly at

high speeds, resulting in personal injury or
property damage. Follow the roof rack cau-
tions when carrying cargo on your roof
rack.
CAUTION!
• To prevent damage to the roof of your
vehicle, do not carry any loads on the
roof rack without the crossbars installed.
The load should be secured and placed
on top of the crossbars, not directly on
the roof. If it is necessary to place the
load on the roof, place a blanket or some
other protection between the load and
the roof surface.
• To avoid damage to the roof rack and
vehicle, do not exceed the maximum
roof rack load capacity of 150 lb (68 kg).
Always distribute heavy loads as evenly
as possible and secure the load
appropriately.
CAUTION!
• Long loads which extend over the wind-
shield, such as wood panels or surf-
boards, or loads with large frontal area
should be secured to both the front and
rear of the vehicle.
• Place a blanket or other protection be-
tween the surface of the roof and the
load.
• Travel at reduced speeds and turn cor-
ners carefully when carrying large or
heavy loads on the roof rack. Wind
forces, due to natural causes or nearby
truck traffic, can add sudden upward lift
to a load. This is especially true on large
flat loads and may result in damage to
the cargo or your vehicle.
• The use of Sport Mode is not recom-
mended when using the Roof Luggage
Rack to carry a load.

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
— Air Bag Warning Light
This warning light will illuminate to indicate 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 warning 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.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid
level conditions. The vehicle should have
service performed, and the brake fluid level
checked.
73

If brake failure is indicated, immediate repair
is necessary.
WARNING!
Driving a vehicle with the red brake light
on is dangerous. Part of the brake system
may have failed. It will take longer to stop
the vehicle. You could have a collision.
Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is re-
quired.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from
the OFF position to the ON/RUN position.
The light should illuminate for approximately
four seconds. The light should then turn off
unless the parking brake is applied or a brake
fault is detected. If the light does not illumi-
nate, have the light inspected by an autho-
rized dealer.The light also will turn on when the parking
brake is applied with the ignition switch in
the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake
application.
— Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays on
while the engine is running, there may be a
malfunction with the charging system. Con-
tact an authorized dealer as soon as possible.
This indicates a possible problem with the
electrical system or a related component.

exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning

SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake perfor-
mance under most braking conditions. The
system automatically prevents wheel lock,
and enhances vehicle control during braking.
The ABS performs a self-check cycle to en-
sure that the ABS is working properly each
time the vehicle is started and driven. During
this self-check, you may hear a slight clicking
sound as well as some related motor noises.
ABS is activated during braking when the
system detects one or more wheels begin to
lock. Road conditions such as ice, snow,
gravel, bumps, railroad tracks, loose debris,
or panic stops may increase the likelihood of
ABS activation(s).
You also may experience the following when
ABS activates:
• The ABS motor noise (it may continue to
run for a short time after the stop).
• The clicking sound of solenoid valves.• Brake pedal pulsations.
• A slight drop of the brake pedal at the end
of the stop.
These are all normal characteristics of ABS.
WARNING!
• The ABS contains sophisticated elec-
tronic equipment that may be suscep-
tible to interference caused by improp-
erly installed or high output radio
transmitting equipment. This interfer-
ence can cause possible loss of anti-lock
braking capability. Installation of such
equipment should be performed by
qualified professionals.
• Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may
lead to a collision. Pumping makes the
stopping distance longer. Just press
firmly on your brake pedal when you
need to slow down or stop.
• The ABS cannot prevent the natural laws
of physics from acting on the vehicle,
nor can it increase braking or steering
efficiency beyond that afforded by the
WARNING!
condition of the vehicle brakes and tires
or the traction afforded.
• The ABS cannot prevent collisions, in-
cluding those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.
• The capabilities of an ABS equipped
vehicle must never be exploited in a
reckless or dangerous manner that could
jeopardize the user’s safety or the safety
of others.
ABS is designed to function with the OEM
tires. Modification may result in degraded
ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light”
will turn on when the ignition is turned to the
ON/RUN mode and may stay on for as long as
four seconds.
If the “Anti-Lock Brake Warning Light” re-
mains on or comes on while driving, it indi-
cates that the anti-lock portion of the brake
system is not functioning and that service is

required. However, the conventional brake
system will continue to operate normally if
the “Anti-Lock Brake Warning Light” is on.
If the “Anti-Lock Brake Warning Light” is on,
the brake system should be serviced as soon
as possible to restore the benefits of anti-lock
brakes. If the “Anti-Lock Brake Warning
Light” does not come on when the ignition is
turned to the ON/RUN mode, have the light
repaired as soon as possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced
Electronic Brake Control system (EBC). This
system includes Electronic Brake Force Dis-
tribution (EBD), Anti-Lock Brake System
(ABS), Brake Assist System (BAS), Hill Start
Assist (HSA), Traction Control System (TCS),
Electronic Stability Control (ESC), and Elec-
tronic Roll Mitigation (ERM). These systems
work together to enhance both vehicle stabil-
ity and control in various driving conditions.Your vehicle may also be equipped with
Trailer Sway Control (TSC), Ready Alert Brak-
ing (RAB), Rain Brake Support (RBS), Dy-
namic Steering Torque (DST), Hill Descent
Control (HDC), and Selec-Speed Control
(SSC).
Your vehicle may also be equipped with
Trailer Sway Control (TSC), Ready Alert Brak-
ing (RAB), Rain Brake Support (RBS), and-
Dynamic Steering Torque (DST).
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the
braking torque between the front and rear
axles by limiting braking pressure to the rear
axle. This is done to prevent overslip of the
rear wheels to avoid vehicle instability, and to
prevent the rear axle from entering ABS be-
fore the front axle.
Brake System Warning Light
The red “Brake System Warning Light” will
turn on when the ignition is turned to the
ON/RUN mode and may stay on for as long as
four seconds.If the “Brake System Warning Light” remains
on or comes on while driving, it indicates that
the brake system is not functioning properly
and that immediate service is required. If the
“Brake System Warning Light” does not
come on when the ignition is turned to the
ON/RUN mode, have the light repaired as
soon as possible.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emer-
gency braking situation by sensing the rate
and amount of brake application and then
applies optimum pressure to the brakes. This
can help reduce braking distances. The BAS
complements the anti-lock brake system
(ABS). Applying the brakes very quickly re-
sults in the best BAS assistance. To receive
the benefit of the system, you must apply
continuous braking pressure during the stop-
ping sequence, (do not “pump” the brakes).
Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake
pedal is released, the BAS is deactivated.
87

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.
The BSM detection zone covers approxi-
mately one lane width on both sides of the
vehicle 12 ft (3.8 m). The zone length starts
at the side of the vehicle, near the B-Pillar,
and extends approximately 10 ft (3 m) be-
yond the rear bumper of the vehicle. The
BSM system monitors the detection zones on
both sides of the vehicle when the vehiclespeed 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 equip-
ment) extends beyond the side of your ve-
hicle, this may result in random false de-
tections on the trailer, and false chimes
when the turn signal is used.
• The Blind Spot Monitoring (BSM) system
may experience drop outs (blinking on and
off) of the side mirror Warning Indicator
lamps when a motorcycle or any small ob-
ject remains at the side of the vehicle for
extended periods of time (more than a
couple of seconds).The area on the rear fascia 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 where the
radar sensors are located with foreign objects
(bumper stickers, bicycle racks, etc.).
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, when the turn signal is
activated during the alert on the side of the
vehicle corresponding to the alert, an audible
(chime) alert can be heard. During this au-
dible (chime) alert, the radio volume will be
reduced. Refer to “Modes Of Operation” in
this section for further information.
Rear Detection Zones
SAFETY
98

The BSM system monitors the detection zone
from three different entry points (side, rear,
front) while driving to see if an alert is neces-
sary. 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.Entering From The Rear
Vehicles that come up from behind your ve-
hicle on either side and enter the rear detec-
tion zone with a relative speed of less than
30 mph (48 km/h).
Overtaking Traffic
If you pass another vehicle slowly with a
relative speed less than 15 mph (24 km/h)
and the vehicle remains in the blind spot for
approximately 1.5 seconds, 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.
The BSM system is designed not to issue an
alert on stationary objects such as guardrails,
posts, walls, foliage, berms, etc. However,
occasionally the system may alert on such
objects. This is normal operation and your
vehicle does not require service.
The BSM system will not alert you of objects
that are traveling in the opposite direction of
the vehicle in adjacent lanes.
WARNING!
The Blind Spot Monitoring system is only
an aid to help detect objects in the blind
spot zones. The BSM system is not de-
signed to detect pedestrians, bicyclists, or
animals. Even if your vehicle is equipped
with the BSM system, always check your
vehicle’s mirrors, glance over your shoul-
der, and use your turn signal before chang-
ing lanes. Failure to do so can result in
serious injury or death.
Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is in-
tended to aid the driver when backing out of
parking spaces where their vision of oncom-
ing 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
detected, alert the driver.
RCP monitors the rear detection zones on
both sides of the vehicle, for objects that are
moving toward the side of the vehicle with a
minimum speed of approximately 5 mphBlind Spot Warning Light
99

(8 km/h), to objects moving a maximum of
approximately 20 mph (32 km/h), such as in
parking lot situations.
NOTE:
In a parking lot situation, oncoming vehicles
can be obscured by vehicles parked on either
side. If the sensors are blocked by other
structures or vehicles, the system will not be
able to alert the driver.
When RCP is on and the vehicle is in RE-
VERSE, the driver is alerted using both the
visual and audible alarms, including reduc-
ing the radio volume.
WARNING!
Rear Cross Path Detection (RCP) is not a
back up 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.
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 information.
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.
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.
