GAIN
The GAIN setting is used to set the trailer brake control
for the specific towing condition and should be changed
as towing conditions change. Changes to towing condi-
tions include trailer load, vehicle load, road conditions
and weather.
Adjusting GAIN
NOTE:This should only be performed in a traffic free
environment at speeds of approximately 20–25 mph
(30–40 km/h).
1. Make sure the trailer brakes are in good working
condition, functioning normally and properly ad-
justed. See your trailer dealer if necessary.
2.Hook up the trailer and make the electrical connections
according to the trailer manufacturer’s instructions.
3. When a trailer with electric/EOH brakes is plugged
in, the trailer connected message should appear in the
EVIC/DID (if the connection is not recognized by the
ITBM, braking functions will not be available), the
GAIN setting will illuminate and the correct type of
trailer must be selected from the EVIC/DID options.
4. Press the UP or DOWN button on the steering wheel

Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

666 STARTING AND OPERATING

When towing a loaded trailer up steep grades at low
speeds (20 mph [32 km/h] or below), holding your
vehicle in first gear (using the ERS shift control) can help
to avoid transmission overheating.
If you regularly tow a trailer for more than 45 minutes of
continuous operation, then change the automatic trans-
mission fluid and filter(s) as specified for#police, taxi,
fleet, or frequent trailer towing.#Refer to the “Mainte-
nance Schedule” for the proper maintenance intervals.
NOTE:Check the automatic transmission fluid level
before towing (6-speed automatic only).
Tow/Haul Mode
To reduce potential for automatic transmission overheat-
ing, activate TOW/HAUL mode when driving in hilly
areas, or select a lower gear range (using the Electronic
Range Select (ERS) shift control) on more severe grades.
Electronic Speed Control — If Equipped
•Do not use in hilly terrain or with heavy loads.
•When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
•Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
668 STARTING AND OPERATING

•Check the runners and cutting edge for excessive wear.
The cutting edge should be¼to½in (6 cm to 1.2 cm)
above ground in snow plowing position.
•Check that snowplow lighting is connected and func-
tioning properly.
Snowplow Prep Package Model Availability
For Information about snowplow applications visit
www.ramtrucks.com or refer to the current Body Build-
ers Guide.
1. The maximum number of occupants in the truck
should not exceed two.
2. The total GVWR or the Front GAWR or the Rear
GAWR should never be exceeded.
3. Cargo capacity will be reduced by the addition of
options or passengers, etc.
The loaded vehicle weight, including the snowplow
system, all aftermarket accessories, driver, passengers,
options, and cargo, must not exceed either the Gross
Vehicle Weight (GVWR) or Gross Axle Weight (GAWR)
ratings. These weights are specified on the Safety Com-
pliance Certification Label on the driver’s side door
opening.
NOTE:Detach the snowplow when transporting pas-
sengers.
Vehicle front end wheel alignment was set to specifica-
tions at the factory without consideration for the weight
of the plow. Front end toe-in should be checked and reset
if necessary at the beginning and end of the snowplow
season. This will help prevent uneven tire wear.
The blade should be lowered whenever the vehicle is
parked.
