This indicator light will illuminate when the cruise control is
ready, but not set. Refer to “Speed Control” in “Starting And
Operating” for further information.
— Speed Control SET Indicator Light — If Equipped
With 3.5 Inch Instrument Cluster Display
This light will turn on when the speed control is set.
Refer to “Speed Control” in “Starting And Operating” for
further information.
— Hill Descent Control (HDC) Indicator Light — If
Equipped
This indicator shows when the Hill Descent Control (HDC)
feature is turned on. The lamp will be on solid when HDC is
armed. HDC can only be armed when the transfer case is in
the “4WD LOW” position and the vehicle speed is less then
20 mph (32 km/h). If these conditions are not met while
attempting to use the HDC feature, the HDC indicator light
will flash on/off. — LaneSense Indicator Light — If Equipped
When the LaneSense system is ON, but not armed, the Lane -
Sense indicator light illuminates solid white. This occurs
when only left, right, or neither lane line has been detected.
If a single lane line is detected, the system is ready to provide
only visual warnings if an unintentional lane departure
occurs on the detected lane line.
Refer to “LaneSense — If Equipped” in “Starting And Oper -
ating” for further information.

SAFETY 211
AUXILIARY DRIVING SYSTEMS
Blind Spot Monitoring (BSM) — If Equipped
The Blind Spot Monitoring (BSM) system uses two
radar-based sensors, located inside the taillights, to detect
highway licensable vehicles (automobiles, trucks, motorcy-
cles, 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. 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 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 rear view mirror and extends
approximately 10 ft (3 m) beyond the rear 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 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 object
remains at the side of the vehicle for extended periods of
time (more than a couple of seconds).

212 SAFETY
The vehicle’s taillights, 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 taillights with foreign objects (bumper stickers, bicycle
racks, etc.).Radar Sensor Locations
If the system detects degraded performance due to contami -
nation or foreign objects, a message will warn you of a
blocked sensor and the warning indicators in side view
mirrors will be on. The warning indicators will remain illu-
minated until blockage clearing conditions are met. First clear the taillights around the sensors of the blockage. After
removing the blockage, the following procedure can be used
to reset the system:
• Cycle the ignition from ON to OFF and then back ON.
If the blockage message is still present after cycling the igni
-
tion and driving in traffic, check again for a blockage.
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. Refer to “Modes Of
Operation” in this section for further information.

SAFETY 217
When RCP is on and the vehicle is in REVERSE (R), the
driver is alerted using both the visual and audible alarms,
including reducing the radio volume.
Modes Of Operation
Three selectable modes of operation are available in the
Uconnect System.
Refer to “Uconnect Settings” in “Multimedia” 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 viewmirror based on a detected 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 present. 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. Whenever 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.
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.

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 reduc
-
tion potential provided by the seat belts and body structure.
WARNING!
• Unapproved modifications or service procedures to the passenger seat assembly, its related components, seat
cover or cushion may inadvertently change the air bag
deployment in case of a frontal collision. This could
result in death or serious injury to the front passenger
if the vehicle is involved in a collision. A modified
vehicle may not comply with required Federal Motor
Vehicle Safety Standards (FMVSS) and/or Canadian
Motor Vehicle Safety Standards (CMVSS).

262 SAFETY
However, if you haven’t healed significantly within a few
days, or if you have any blistering, see your doctor imme-
diately.
• As the air bags deflate, you may see some smoke-like parti -
cles. The particles are a normal by-product of the process
that generates the non-toxic gas used for air bag inflation.
These airborne particles may irritate the skin, eyes, nose, or
throat. If you have skin or eye irritation, rinse the area with
cool water. For nose or throat irritation, move to fresh air.
If the irritation continues, see your doctor. If these particles
settle on your clothing, follow the garment manufacturer’s
instructions for cleaning.
Do not drive your vehicle after the air bags have deployed. If
you are involved in another collision, the air bags will not be
in place to protect you. NOTE:
• Air bag covers may not be obvious in the interior trim, but
they will open during air bag deployment.
• After any collision, the vehicle should be taken to an authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending on
the nature of the event, the ORC will determine whether to
have the Enhanced Accident Response System perform the
following functions:
• Cut off fuel to the engine (If Equipped)
• Cut off battery power to the electric motor (If Equipped)
• Flash hazard lights as long as the battery has power
• Turn on the interior lights, which remain on as long as the battery has power or for 15 minutes from the intervention
of the Enhanced Accident Response System
• Unlock the power door locks
WARNING!
Deployed air bags and seat belt pretensioners cannot
protect you in another collision. Have the air bags, seat
belt pretensioners, and the seat belt retractor assemblies
replaced by an authorized dealer immediately. Also,
have the Occupant Restraint Controller System serviced
as well.

STARTING AND OPERATING 313
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD and
4LOW) are located in the instrument cluster and indicate the
current and desired transfer case selection. When you select
a different transfer case position, the indicator lights will do
the following:
1. The current position indicator light will turn OFF.
2. The selected position indicator light will flash until thetransfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and remain ON.
If the transfer case does not shift into the desired position,
one or more of the following events may occur:
1. The indicator light for the current position will remain ON.
2. The newly selected position indicator light will continue to flash.
3. If the transfer case will not shift, there will be a cluster
message stating the 4WD shift has canceled. NOTE:
Before retrying a selection, make certain that all the neces
-
sary requirements for selecting a new transfer case position
have been met. To retry the selection, push the current posi -
tion, wait five seconds, and retry selection. To find the shift
requirements, refer to the "Shifting Procedure" for your
transfer case, located in this section.
The “SVC 4WD Warning Light” monitors the electronic shift
four-wheel drive system. If this light remains on after engine
start up or illuminates during driving, it means that the
four-wheel drive system is not functioning properly and that
service is required.
NOTE:
Do not attempt to make a shift while only the front or rear
wheels are spinning. This could cause damage to driveline
components.
WARNING!
Always engage the parking brake when powering down
the vehicle if the “SVC 4WD Warning Light” is

350 STARTING AND OPERATING
Distance Setting 1 Bar (Short)
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 displays the “Sensed Vehicle Indicator”
icon, 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. (Refer to the information on ACC Activation).
The maximum braking applied by ACC is limited; however,
the driver can always apply the brakes manually, if neces -
sary.
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.
