•Adjusting a seat while driving may be dangerous.
Moving a seat while driving could result in loss of
control which could cause a collision and serious
injury or death.

belts and while the vehicle is parked. Serious
injury or death could result from a poorly adjusted
seat belt.

swing (dump) forward on manual recliner seats. This
“dump” feature allows access to the storage bin behind
the seat.

• Do not stand or lean in front of the seat while
actuating the handle. The seatback may swing
forward and hit you causing injury.
• To avoid injury, place your hand on the seatback
and actuate the handle, then position the seatback
in the desired position.

PARKVIEW® REAR BACK UP CAMERA — IF
EQUIPPED
Your vehicle may be equipped with the ParkView® Rear
Back Up Camera that allows you to see a image of the
rear surroundings of your vehicle whenever the shift
lever is put into REVERSE. The image will be displayed
in the rearview mirror display (if equipped) or
Uconnect® screen (if equipped) 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 to the left of the
tailgate handle.
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 camera image will be dis-
played for up to 10 seconds after shifting out of
RE-
VERSE unless the forward vehicle speed exceeds 8 mph
(13 km/h), the transmission is shifted into PARKor the
ignition is switched 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. The active guide lines will show separate zones
that will help indicate the distance to the rear of the
vehicle.
NOTE: For further information about how to access and
change the programmable features of the ParkView®
Rear Backup Camera, refer to “Uconnect® Settings” in
“Understanding Your Instrument Panel” for further in-

TIRE SAFETY INFORMATION
Tire MarkingsNOTE:
•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 Pis 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.

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% of the vehicle’s GTW 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
The trailer sway control can be a mechanical telescoping
link that can be installed between the hitch receiver and
the trailer tongue that typically provides adjustable fric-
tion associated with the telescoping motion to dampen
any unwanted trailer swaying motions while traveling.If equipped, the electronic Trailer Sway Control (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 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 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
