2018 Ram 4500 Chassis Cab change wheel

If the transmission cannot be reset, autho-
rized dealer service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift con-
trol allows the driver to limit the highest
available gear when the transmission is in
DRIVE. For example, if you set the transmis-
sion gear limit to 4 (fourth gear), the trans-
mission will not shift above fourth gear, but
will shift through the lower gears normally.
You can switch between DRIVE and ERS
mode at any vehicle speed. When the gear
selector is in the DRIVE position, the trans-
mission will operate automatically, shifting
between all available gears. Tapping the ERS
(-) switch will activate ERS mode, display the
current gear in the instrument cluster, and
set that gear as the top available gear. Once
in ERS mode, tapping (-) or (+) will change
the top available gear.To exit ERS mode, simply push and hold the
ERS (+) switch until the gear limit display
disappears from the instrument cluster.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the ve-
hicle could skid, causing a collision or
personal injury.
NOTE:
To select the proper gear position for maxi-
mum deceleration (engine braking), simply
push and hold the ERS (-) switch. The trans-
mission will shift to the range from which the
vehicle can best be slowed down.
CAUTION!
When using ERS for engine braking while
descending steep grades, be careful not to
overspeed the engine. Apply the brakes as
needed to prevent engine overspeed.

GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake
control power output to the trailer brakes in
0.5 increments. The GAIN setting can be
increased to a maximum of 10 or decreased
to a minimum of 0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer
brake control for the specific towing condi-
tion and should be changed as towing condi-
tions change. Changes to towing conditions
include trailer load, vehicle load, road condi-
tions 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 goodworking condition, functioning normally
and properly adjusted. See your trailer
dealer if necessary. 2. Hook up the trailer and make the electri-
cal 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 instrument cluster
display (if the connection is not recog-
nized 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 instrument
cluster display options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” ap-
pears on the screen.
5. Push the RIGHT arrow on the steering wheel to enter “TRAILER TOW”.
6. Push the UP or DOWN buttons until the Trailer Brake Type appears on the screen. 7. Push the RIGHT arrow and then push the
UP or DOWN buttons until the proper
Trailer Brake Type appears on the screen.
8. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of
20–25 mph (30–40 km/h) and squeeze
the manual brake control lever
completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting;
if the trailer wheels turn freely, increase
the GAIN setting.
Repeat steps 8 and 9 until the GAIN setting
is at a point just below trailer wheel lockup. If
towing a heavier trailer, trailer wheel lockup
may not be attainable even with the maxi-
mum GAIN setting of 10.

CAUTION!
• When installing the power distributioncenter cover, it is important to ensure
the cover is properly positioned and fully
latched. Failure to do so may allow water
to get into the power distribution center
and possibly result in an electrical sys-
tem failure.
• When replacing a blown fuse, it is impor-
tant to use only a fuse having the correct
amperage rating. The use of a fuse with
a rating other than indicated may result
in a dangerous electrical system over-
load. If a properly rated fuse continues
to blow, it indicates a problem in the
circuit that must be corrected.
JACKING AND TIRE CHANGING
WARNING!
• Do not attempt to change a tire on theside of the vehicle close to moving traf-
fic. Pull far enough off the road to avoid
the danger of being hit when operating
the jack or changing the wheel.
• Being under a jacked-up vehicle is dan-
gerous. The vehicle could slip off the
jack and fall on you. You could be
crushed. Never put any part of your body
under a vehicle that is on a jack. If you
need to get under a raised vehicle, take
it to a service center where it can be
raised on a lift.
• Never start or run the engine while the
vehicle is on a jack.
• The jack is designed to be used as a tool
for changing tires only. The jack should
not be used to lift the vehicle for service
purposes. The vehicle should be jacked
on a firm level surface only. Avoid ice or
slippery areas.
4500/5500 Models
These vehicles do not come equipped with a
jack.
NOTE:
Jacking and tire changing on 4500/
5500 models should be performed by an
authorized dealer, or knowledgeable service
personnel with the appropriate heavy duty
equipment, like a tire service company.
Preparations For Jacking
1. Park the vehicle on a firm, level surface.
Avoid ice or slippery areas.
WARNING!
Do not attempt to change a tire on the side
of the vehicle close to moving traffic, pull
far enough off the road to avoid being hit
when operating the jack or changing the
wheel.
2. Place the gear selector into PARK. On four-wheel drive vehicles, shift the trans-
fer case to the 4L position.
3. Turn on the Hazard Warning flasher.

Passengers should not remain in the vehicle
when the vehicle is being jacked.Jacking Instructions 4500 And
5500 Series
WARNING!
Carefully follow these tire changing warn-
ings to help prevent personal injury or
damage to your vehicle:
• Always park on a firm, level surface as far from the edge of the roadway as
possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the
wheel to be raised.
• Set the parking brake firmly and set the
transmission in PARK.
• Never start or run the engine with the
vehicle on a jack.
• Do not let anyone sit in the vehicle when
it is on a jack.
• Do not get under the vehicle when it is
on a jack. If you need to get under a
raised vehicle, take it to a service center
where it can be raised on a lift.
• Only use the jack in the positions indi-
cated and for lifting this vehicle during a
tire change.
WARNING!
• If working on or near a roadway, beextremely careful of motor traffic.

It is recommended you contact your autho-
rized tire dealer or original equipment dealer
with any questions you may have on tire
specifications or capability. Failure to use
equivalent replacement tires may adversely
affect the safety, handling, and ride of your
vehicle.
WARNING!
• Do not use a tire, wheel size, load rating,or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and per-
formance characteristics, resulting in
changes to steering, handling, and brak-
ing of your vehicle. This can cause un-
predictable handling and stress to steer-
ing and suspension components. You
could lose control and have a collision
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index
or capacity, other than what was origi-
nally equipped on your vehicle. Using a
WARNING!
tire with a smaller load index could re-
sult in tire overloading and failure. You
could lose control and have a collision.
• Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false speedom-
eter and odometer readings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all sea-
sons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identified
by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
Summer Or Three Season Tires —
If Equipped
Summer tires provide traction in both wet
and dry conditions, and are not intended to
be driven in snow or on ice. If your vehicle is
equipped with Summer tires, be aware these
tires are not designed for Winter or cold
driving conditions. Install Winter tires on your
vehicle when ambient temperatures are less
than 40°F (5°C) or if roads are covered with
ice or snow. For more information, contact an
authorized dealer.
Summer tires do not contain the all season
designation or mountain/snowflake symbol
on the tire sidewall. Use Summer tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
WARNING!
Do not use Summer tires in snow/ice con-
ditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.
