2017 RAM CHASSIS CAB width

Reclining Rear Seats — If Equipped
The recliner handle is located on the outside of the seat
cushion. To adjust the seatback, lift upward on the handle,
lean back on the seatback and when you reach the desired
position, release the handle.
WARNING!Do not ride with the seatback reclined so that the
shoulder belt is no longer resting against your chest. In
a collision, you could slide under the seat belt, which
could result in serious injury or death. 40-20-40 Front Bench Seat — If Equipped
The seat is divided into three segments. The outboard seat
portions are each 40% of the total width of the seat. On
some models, the back of the center portion (20%) easily
folds down to provide an armrest/center storage compart-
ment.
Head Restraints
Head restraints are designed to reduce the risk of injury by
restricting head movement in the event of a rear impact.
Head restraints should be adjusted so that the top of the
head restraint is located above the top of your ear.
WARNING!• All occupants, including the driver, should not oper-
ate a vehicle or sit in a vehicle’s seat until the head
restraints are placed in their proper positions in
order to minimize the risk of neck injury in the event
of a crash.
• Head restraints should never be adjusted while the
vehicle is in motion. Driving a vehicle with the head
restraints improperly adjusted or removed could
cause serious injury or death in the event of a
collision.Rear Seat Recliner Handle116 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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 “Under-
standing Your Instrument Panel” for further information.
The following table shows the approximate distances for
each zone:
Zones Distance to the rear of the vehicle
Red 0-1ft(0-30cm)
Yellow 1 ft - 6.5 ft (30 cm - 2m)
Green 6.5 ft or greater (2 m or greater)
WARNING!Drivers must be careful when backing up even when
using the ParkView Rear Back Up Camera. Always
check carefully behind your vehicle, and be sure to (Continued) WARNING! (Continued)check for pedestrians, animals, other vehicles, obstruc-
tions, or blind spots before backing up. You are re-
sponsible 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!• To avoid vehicle damage, ParkView should only be
used as a parking aid. The ParkView camera is
unable to view every obstacle or object in your drive
path.
• To avoid vehicle damage, the vehicle must be driven
slowly when using ParkView to be able to stop in
time when an obstacle is seen. It is recommended
that the driver look frequently over his/her shoulder
when using ParkView.
NOTE: If snow, ice, mud, or any foreign substance builds
up on the camera lens, clean the lens, rinse with water, and
dry with a soft cloth. Do not cover the lens.158 UNDERSTANDING THE FEATURES OF YOUR 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 designation.
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 preceding the
size designation. Example: LT235/85R16. • Temporary spare tires are designed for temporary emer-
gency use only. Temporary high pressure 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 U.S. design stan-
dards and it begins with the tire diameter molded into
the sidewall. Example: 31x10.5 R15 LT.366 STARTING AND OPERATING

Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. 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 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 truck. These kind 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
brake control, thereby enhancing towing safety. The addi-
tion 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 GAWR require-
ments. 5STARTING AND OPERATING 405
