2015 JEEP GRAND CHEROKEE Owners Manual

When the vehicle is started, the BSM warning light will
momentarily illuminate in both outside 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 detection zone covers approximately one lane
width on both sides of the vehicle (12 ft or 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 de-
tection 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 equipment) extends
beyond the side of your vehicle, this may result in the
BSM warning light remaining illuminated the entire
time the vehicle is in a forward gear.
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 (bum-
per 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 to sounding an
audible (chime) alert and reducing the radio volume.
Refer to “Modes Of Operation” for further information.
Sensor Location
136 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

The BSM system monitors the detection zone from three
different entry points (side, rear, front) while driving to
see if an alert is necessary. 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.
Warning Light Location

Entering From The Rear
Vehicles that come up from behind your vehicle on either
side and enter the rear detection 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 10 mph (16 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 10 mph
(16 km/h), the warning light will not illuminate.
Rear Monitoring
Overtaking/Approaching
138 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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
(Continued)
WARNING!(Continued)
system is not designed to detect pedestrians, bicy-
clists, or animals. Even if your vehicle is equipped
with the BSM system, always check your vehicles
mirrors, glance over your shoulder, and use your turn
signal before changing lanes. Failure to do so can
result in serious injury or death.
Rear Cross Path
The Rear Cross Path (RCP) feature is intended to aid the
driver when backing out of parking spaces where their
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 detected, alert the driver.
Opposing Traffic
140 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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
3 mph (5 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 REVERSE, the
driver is alerted using both the visual and audible
alarms, including reducing the radio volume.
WARNING!
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 back-
ing 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/
Customer Programmable Features” in “Understanding
Your Instrument Panel” 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 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 appro-
priate 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 de-
tected 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.
