2015 JEEP GRAND CHEROKEE width

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.

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/gear selector is put into REVERSE. The
image will be displayed on the Navigation/Multimedia
radio display screen 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.
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 rear view image with dynamic
grid lines will be displayed for up to 10 seconds after
shifting out of#REVERSE#unless the forward vehicle
speed exceeds 8 mph (13 km/h), the transmission is
shifted into#PARK#or the ignition is switched to the OFF
position.
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 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. The active guide lines will show separate zones
that will help indicate the distance to the rear of the
vehicle while a dashed center-line will indicate the center

TIRE SAFETY INFORMATION
Tire Markings
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!(Continued)
you use a standard weight-carrying hitch, you could
lose control of your vehicle and cause a collision.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR. Refer to “Vehicle Loading/Vehicle Certifica-
tion Label” in “Starting and Operating” for further
information.
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.
