2015 JEEP CHEROKEE width

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.

PARKVIEW® REAR BACK UP CAMERA — IF
EQUIPPED
Your vehicle may be equipped with the ParkView® Rear
Back Up Camera that allows you to see an on-screen
image of the rear surroundings of your vehicle whenever
the shift lever is put into REVERSE. The image will be
displayed in the touchscreen display along with a caution
note to “check entire surroundings” across the top of the
screen. After five seconds this note will disappear. The
ParkView® camera is located on the rear of the vehicle
above the rear License plate.
NOTE:The ParkView® Rear Back Up Camera has pro-
grammable modes of operation that may be selected
through the Uconnect® System. Refer to “Uconnect®
Settings” in “Understanding Your Instrument Panel” for
further information.
When the vehicle is shifted out of REVERSE (with camera
delay turned OFF), the rear camera mode is exited and
the navigation or audio screen appears again. When the
vehicle is shifted out of REVERSE (with camera delay
turned ON), the camera image will continue to be
displayed for up to 10 seconds after shifting out of
REVERSE unless the vehicle speed exceeds 8 mph
(13 km/h), the vehicle is shifted into PARK or the
vehicles ignition is cycled to the OFF position.
When enabled, active guide lines are overlaid on the
image to illustrate the width of the vehicle and its
projected backup path based on the steering wheel
position. A dashed center line overlay indicates the center
of the vehicle to assist with parking or aligning to a
hitch/receiver.
When enabled, fixed guide lines are overlaid on the
image to illustrate the width of the vehicle.
Different colored zones indicate the distance to the rear of
the vehicle.

NOTE:
•P (Passenger) — Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
•European — Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letter#P#is absent from this tire
size designation. Example: 215/65R15 96H.
•LT (Light Truck) — Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
•Temporary spare tires are designed for temporary
emergency use only. Temporary high pressure com-
pact spare tires have the letter “T” or “S” molded into
the sidewall preceding the size designation. Example:
T145/80D18 103M.
•High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.

WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have a collision.
Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. The recommended tongue weight
is 10% to 15% for a conventional hitch. You must consider
this as part of the load on your vehicle.
Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control — Mechanical
The trailer sway control is a telescoping link that can be
installed between the hitch receiver and the trailer tongue
that typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch ball or
some other connecting point of the vehicle. These kinds
of hitches are the most popular on the market today and
they are commonly used to tow small and medium sized
trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying lever-
age through spring (load) bars. They are typically used
for heavier loads to distribute trailer tongue weight to the
