2015 JEEP CHEROKEE light

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 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 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) will also be
muted.

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

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.

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.

This system automatically turns the headlights on or off
according to ambient light levels. To turn the system on,
rotate the headlight switch clockwise to the last detent for
automatic headlight operation. When the system is on,
the headlight time delay feature is also on. This means
the headlights will stay on for up to 90 seconds after you
place the ignition into the OFF position. To turn the
automatic system off, move the headlight switch out of
the AUTO position.

lights will come on in the automatic mode.
Headlights On With Wipers (Available With
Automatic Headlights Only)
When this feature is active, the headlights will turn on
after the wipers are turned on if the headlight switch is
placed in the AUTO position and programmable feature
is set to ON. In addition, the headlights will turn off
when the wipers are turned off if they were turned on by
this feature.
NOTE:The Headlights On with Wipers feature can be
turned on or off using the Uconnect® System. Refer to
“Uconnect® Settings/Customer Programmable Fea-
tures” in “Understanding Your Instrument Panel” for
further information.
Headlight Time Delay
This feature provides the safety of headlight illumination
for up to 90 seconds (programmable) when leaving your
vehicle in an unlit area.
To activate the delay feature, place the ignition in the OFF
position while the headlights are still on. Then, turn off

If you turn the headlights or parking lights on, or place
the ignition in ACC or RUN, the system will cancel the
delay.
If you turn the headlights off before the ignition, they will
turn off in the normal manner.
NOTE:
•The lights must be turned off within 45 seconds of
placing the ignition in the OFF position to activate this
feature.
•The headlight delay time is programmable using the
Uconnect® System, refer to “Uconnect® Settings” in
“Understanding Your Instrument Panel” for further
information.
Automatic High Beam Headlamp Control — If
Equipped
The Automatic High Beam Headlamp Control system
provides increased forward lighting at night by automat-
ing high beam control through the use of a digital camera
mounted on the inside rearview mirror. This camera
detects vehicle specific light and automatically switches
from high beams to low beams until the approaching
vehicle is out of view.
NOTE:
•The Automatic High Beam Headlamp Control can be
turned on or off using the Uconnect® System. Refer to
“Uconnect® Settings” in “Understanding Your Instru-
ment Panel” for further information.
•Broken, muddy, or obstructed headlights and taillights
of vehicles in the field of view will cause headlights to
remain on longer (closer to the vehicle). Also, dirt, film,
170 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

and other obstructions on the windshield or camera
lens will cause the system to function improperly.
•To opt out of the Advanced Auto High-Beam Sensitiv-
ity Control (default) and enter Reduced High-Beam
Sensitivity Control (not recommended), toggle high-
beam lever 6 full on/off cycles within 10 seconds of
ignition ON. System will return to default setting upon
ignition off.
If the windshield or Automatic High Beam Headlamp
Control mirror is replaced, the mirror must be re-aimed
to ensure proper performance. See your local authorized
dealer.
To Activate
1. Turn the headlight switch to the AUTO headlight
position.
2. Push the multifunction lever away from you (toward
front of vehicle) to engage the high beam mode.
NOTE:This system will not activate until the vehicle is
at or above 15 mph (24 km/h).
To Deactivate
1. Pull the multifunction lever toward you (or rearward
in car) to manually deactivate the system (normal
operation of low beams).
2. Push back on the multifunction lever once again to
reactivate the system.
