2019 Ram ProMaster width

When displayed, static grid lines will illustrate the width of
the vehicle and will show separate zones that will help
indicate the distance to the rear of the vehicle. The follow-
ing table shows the approximate distances for each zone:
ZoneDistance To The Rear Of The Vehicle
Red 0 - 1 ft (0 - 30 cm)
Yellow 1 ft - 3 ft (30 cm - 1 m)
Green 3 ft or greater (1 m or greater)
WARNING!
Drivers must be careful when backing up even when
using the Rear Back Up Camera. Always check care-
fully 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!
•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.

Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your vehicle
and trailer when weighed in combination.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tempo-
rary) loaded in or on the trailer in itsloaded and ready for
operation condition.
The recommended way to measure GTW is to put your
fully loaded trailer on a vehicle scale. The entire weight of
the trailer must be supported by the scale.
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 infor-
mation.
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. 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
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 friction
associated with the telescoping motion to dampen any
unwanted trailer swaying motions while traveling.

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 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 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 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.
