towing capacity Ram 4500 Chassis Cab 2018 User Guide

• Trailer brakes are recommended for trailersover 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 vehi-
cle's hydraulic brake lines. It can overload
your brake system 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 distance. When towing you
should allow for additional space be-
tween 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 Elec-
tric 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 compatible with ITBM. The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the
left to activate power to the trailer's electric
brakes independent of the tow vehicle's
brakes. If the manual brake control lever is
activated while the brake is also applied, the
greater of the two inputs determines the
power sent to the trailer brakes.
The trailer and the vehicle's brake lamps will
come on when either vehicle braking or
manual trailer brakes are applied.
Trailer Brake Status Indicator Light
This light indicates the trailer electrical con-
nection status.
If no electrical connection is detected after
the ignition is turned on, pushing the GAIN
adjustment button or sliding the manual
brake control lever will display the GAIN
setting for 10 seconds and the “Trailer Brake
Status Indicator Light” will not be displayed.
If a fault is detected in the trailer wiring or the
Integrated Trailer Brake Module (ITBM), the
“Trailer Brake Status Indicator Light” will flash.

To determine the maximum loading condi-
tions 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 appli-
cable) should never exceed the weight refer-
enced here.
Steps For Determining Correct Load
Limit—
(1) Locate the statement “The com-
bined 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 lug-
gage 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. Consult
this manual to determine how this
reduces the available cargo and lug-
gage 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 ex-
amples on how to calculate total load,
cargo/luggage, and towing capacities of
your vehicle with varying seating configura-
tions 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).
