ParkSense will reduce the volume of the radio
when it is sounding an audio tone.
Clean the ParkSense sensors regularly, taking
care not to scratch or damage them. The
sensors must not be covered with ice, snow,
slush, mud, dirt or debris. Failure to do so can
result in the system not working properly. The
ParkSense system might not detect an obstacle
behind the fascia/bumper, or it could provide a
false indication that an obstacle is behind the
fascia/bumper.
Ensure the ParkSense system is off if objects
such as bicycle carriers, trailer hitches, etc., are
placed within 12 inches (30 cm) from the rear
fascia/bumper. Failure to do so can result in the
system misinterpreting a close object as a
sensor problem, causing the “PARKSENSE
UNAVAILABLE SERVICE REQUIRED” message to
be shown in the instrument cluster display.
PARKVIEW REAR BACK UP CAMERA
The ParkView Rear Back Up Camera allows you to
see an on-screen image of the rear surroundings of
your vehicle whenever the gear selector is put into
REVERSE. The ParkView camera is located on the
rear of the vehicle above the rear license plate. 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.
NOTE:The ParkView Rear Back Up Camera has program -
mable modes of operation that may be selected
through the Uconnect system Ú page 120.If your vehicle is equipped with the Camera Delay
feature and it is turned on, the rear camera image
will be displayed for up to 10 seconds when the
vehicle is shifted out of REVERSE. However, this
feature is canceled if the forward vehicle speed
exceeds 8 mph (13 km/h), the transmission is
shifted into PARK, the vehicle's ignition is placed in
the OFF position, or by pressing the image defeat X
button.
When the vehicle is shifted out of REVERSE with
Camera Delay turned off, the rear camera mode is
exited and the last touchscreen appears again.
When enabled, active guidelines 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 guidelines will show
separate zones that will help indicate the distance
to the rear of the vehicle.
If the vehicle speed remains below 8 mph (13 km/
h), the rear view camera image will continue to be
displayed until the transmission is shifted into
PARK, the vehicle’s ignition is placed in the OFF
position, or the image defeat X button is pressed.
Different colored zones indicate the distance to
the rear of the vehicle.
WARNING!
Drivers must be careful when backing up even
when using the Rear Park Assist system. Always
check carefully behind your vehicle, and be sure
to check for pedestrians, animals, other
vehicles, obstructions, or blind spots before
backing up. You are responsible for the safety of
your surroundings and must continue to pay
attention while backing up. Failure to do so can
result in serious injury or death.
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle, including
small obstacles. Parking curbs might be
temporarily detected or not detected at all.
Obstacles located above or below the sensors
will not be detected when they are in close
proximity.
The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time
when an obstacle is detected. It is recom
-
mended that the driver looks over his/her
shoulder when using ParkSense.

112STARTING AND OPERATING
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable 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 Ú page 110.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch
ball by the trailer. You must consider this as part of
the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied
by the maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical 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.
If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
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 commonly used to tow
small and medium sized trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute trailer
tongue weight to the tow vehicle's front axle and
the trailer axle(s). When used in accordance with
the manufacturer's directions, it provides for a
more level ride, offering more consistent steering
and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway control also dampens sway caused by traffic and
crosswinds and contributes positively to tow
vehicle and trailer stability. Trailer sway control and
a weight distributing (load equalizing) hitch are
recommended for heavier Tongue Weights (TW)
and may be required depending on vehicle and
trailer configuration/loading to comply with Gross
Axle Weight Rating (GAWR) requirements.
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.
WARNING!
An improperly adjusted Weight Distributing
Hitch system may reduce handling, stability,
braking performance, and could result in a
collision.
Weight Distributing Systems may not be
compatible with Surge Brake Couplers.
Consult with your hitch and trailer manufac-
turer or a reputable Recreational Vehicle
dealer for additional information.

184SAFETY
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM) —
I
F EQUIPPED
BSM uses two radar sensors, located inside the
rear fascia/bumper, to detect highway licensable
vehicles (automobiles, trucks, motorcycles, 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.
Automatic Transmission Vehicles
The BSM system sensors operate when the vehicle
is in any forward gear. Manual Transmission Vehicles
The BSM system sensors operate when the vehicle
is in any gear.

BSM Warning Light

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
rearview mirror and extends approximately 10 ft
(3 m) beyond the rear fascia/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 BSM system detection zone DOES NOT
change if your vehicle is towing a trailer. There -
fore, 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 BSM system may experience dropouts
(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).
The area on the rear fascia/bumper 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/bumper where the
radar sensors are located with foreign objects
(bumper stickers, bicycle racks, etc.).

Tire Markings

NOTE:
P (Passenger) — Metric tire sizing is based on US
design standards. P-Metric tires have the letter
“P” molded into the sidewall preceding the size
designation. Example: P215/65R15 95H.
European — Metric tire sizing is based on Euro -
pean design standards. Tires designed to this
standard have the tire size molded into the side -
wall 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
US 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 preceding the size designation.
Example: LT235/85R16.
Temporary spare tires are designed for tempo -
rary emergency use only. Temporary high pres -
sure compact 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 US design
standards and it begins with the tire diameter
molded into the sidewall. Example: 31x10.5
R15 LT.
