2018 Ram 3500 Chassis Cab towing capacity

Towing Requirements — Trailer Brakes
•Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible per-
sonal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).
WARNING!
• Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have a collision.
• Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in a collision.
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.
Integrated Trailer Brake Module — If Equipped
Your vehicle may have an Integrated Trailer Brake Module
(ITBM) for Electric and Electric Over Hydraulic (EOH)
trailer brakes.
NOTE: This module has been designed and verified with
electric trailer brakes and new electric over hydraulic
systems. Some previous EOH systems may not be compat-
ible with ITBM.
300 STARTING AND OPERATING

Tire And Loading Information Placard
This placard tells you important information about the:
1. Number of people that can be carried in the vehicle.
2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear, and sparetires.Loading
The vehicle maximum load on the tire must not exceed the
load carrying capacity of the tire on your vehicle. You will
not exceed the tire’s load carrying capacity if you adhere to
the loading conditions, tire size, and cold tire inflation
pressures specified on the Tire and Loading Information
placard in “Vehicle Loading” in the “Starting And Operat-
ing” section of this manual.
NOTE: Under a maximum loaded vehicle condition, gross
axle weight ratings (GAWRs) for the front and rear axles
must not be exceeded.
For further information on GAWRs, vehicle loading, and
trailer towing, refer to “Vehicle Loading” in the “Starting
And Operating” section of this manual.
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX kg or
XXX lbs” on the Tire and Loading Information placard. The
combined weight of occupants, cargo/luggage and trailer
tongue weight (if applicable) should never exceed the
weight referenced here.

Steps For Determining Correct Load Limit—
(1) Locate the statement “The combined weight of
occupants and cargo should never exceed XXX kg or
XXX lbs.” on your vehicle’s placard.
(2) Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
(3) Subtract the combined weight of the driver and
passengers from XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of
cargo and luggage load capacity. For example, if “XXX”
amount equals 1400 lbs. and there will be five 150 lb
passengers in your vehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1400-750
(5x150) = 650 lbs.)
(5) Determine the combined weight of luggage and
cargo being loaded on the vehicle. That weight may not
safely exceed the available cargo and luggage load
capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from
your trailer will be transferred to your vehicle. Consultthis manual to determine how this reduces the available
cargo and luggage load capacity of your vehicle.
Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg and there will
be five 68 kg passengers in your vehicle, the amount of
available cargo and luggage load capacity is 295 kg (635-
340 (5x68) = 295 kg) as shown in step 4.
NOTE:
•
If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. The following
table shows examples on how to calculate total load,
cargo/luggage, and towing capacities of your vehicle
with varying seating configurations and number and
size of occupants. This table is for illustration purposes
only and may not be accurate for the seating and load
carry capacity of your vehicle.
• For the following example, the combined weight of
occupants and cargo should never exceed 865 lbs
(392 kg).
