2019 Ram 1500 Air suspension

Recommended Distribution Hitch Adjustment
Towing With 1500 Air Suspension
1. Set air suspension to normal ride height. No action isrequired if already in normal ride height.
NOTE: The vehicle must remain in the engine run position
with all doors closed while attaching a trailer for proper
leveling of the air suspension system.
2. Position the truck to be ready to connect to the trailer (do not connect the trailer).
3. Under the instrument cluster or touch screen radio settings, enable tire jack mode. Tire jack mode will be
canceled and procedure must be restarted if the vehicle
is driven at speeds above 5mph (8 kmh).
4. Measure the height of the top of the front wheel opening on the fender to ground, this is height H1. 5. Attach the trailer to the vehicle without the weight
distribution bars connected.
6. Measure the height of the top of the front wheel opening on the fender to ground, this is height H2.
7. Install and adjust the tension in the weight distributing bars per the manufacturers’ recommendations so that
the height of the front fender is approximately (H2-H1)/
3+H1 (about 1/3 the difference between H2 and H1
above normal ride height [H1]).

Air Suspension System
To aid in attaching/detaching the trailer from the vehicle,
the air suspension system can be used. Refer to “Air
Suspension System” in “Starting And Operating” for fur-
ther information.
NOTE:The vehicle must remain in the engine running
position while attaching a trailer for proper leveling of the
air suspension system.
SNOWPLOW
NOTE: Do not use this model vehicle for snowplow
applications.
WARNING!
Snowplows and other aftermarket equipment should
not be added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in
the front end structure. The airbags could deploy
unexpectedly or could fail to deploy during a collision
resulting in serious injury or death.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision.
Do not expect that the airbag will perform as described
earlier in this manual.
CAUTION!
Using this vehicle for snowplow applications can
cause damage to the vehicle.6

NOTE:
• When towing your vehicle, always follow applicable

Highway Safety offices for additional details. •
Vehicles equipped with Active-Level Four Corner Air
Suspension must be placed in Transport mode before
tying them down (from the body) on a trailer or flatbed
truck. Refer to “Active-Level Four Corner Air Suspen-
sion – If Equipped” for more information. If the vehicle
cannot be placed in Transport mode (for example, en-
gine will not run), tie-downs must be fastened to the
axles (not to the body). Failure to follow these instruc-
tions may cause fault codes to be set and/or cause loss
of proper tie-down tension.

Recreational Towing — Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is al-
lowedONLY if the rear wheels are OFFthe ground. This
may be accomplished using a tow dolly or vehicle trailer. If
using a tow dolly, follow this procedure:
NOTE: If vehicle is equipped with air suspension, ensure
the vehicle is set to Normal Ride Height.
1. Properly secure the dolly to the tow vehicle, following the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Apply the parking brake. Place the transmission in PARK.
4. Properly secure the rear wheels to the dolly, following the dolly manufacturer’s instructions.
5. Turn the ignition OFF.
6. Install a suitable clamping device, designed for towing, to secure the front wheels in the straight position.
CAUTION!
Towing with the rear wheels on the ground will cause
severe transmission damage. Damage from improper
towing is not covered under the New Vehicle Limited
Warranty.
Recreational Towing — Four-Wheel Drive Models
NOTE: The transfer case must be shifted into NEUTRAL
(N) for recreational towing. The transmission must be
shifted into PARK for recreational towing. Refer to the
following for the proper transfer case NEUTRAL (N)
shifting procedure for your vehicle.
CAUTION!
• DO NOT dolly tow any 4WD vehicle. Towing with
only one set of wheels on the ground (front or rear)
will cause severe transmission and/or transfer case
damage. Tow with all four wheels either ON the
ground, or OFF the ground (using a vehicle trailer).
• Tow only in the forward direction. Towing this
vehicle backwards can cause severe damage to the
transfer case.

2. Press and hold the brake pedal.
3. Shift the transmission to NEUTRAL. The driver’s doormust be closed (or the driver’s seat belt buckled) so that
the transmission will remain in NEUTRAL when the
brake pedal is released.
NOTE: If vehicle is equipped with air suspension, ensure
the vehicle is set to Normal Ride Height.
4. Using a ballpoint pen or similar object, push and hold the recessed transfer case NEUTRAL (N) button (at the
center of the transfer case switches). The NEUTRAL (N)
indicator light will illuminate, and remain lit, when the
shift to NEUTRAL (N) is complete. After the shift is
completed and the NEUTRAL (N) light stays on, release
the NEUTRAL (N) button.
5. Release the parking brake.
6. Shift the transmission into REVERSE. 7. Release the brake pedal for five seconds and ensure that
there is no vehicle movement.
8. Repeat steps 6 and 7 with the transmission in DRIVE.
9. Shift the transmission to NEUTRAL. Apply the parking brake. Turn OFF the engine. For vehicles with Keyless
Enter-N-Go, push and hold the ENGINE START/STOP
button until the engine shuts off. The transmission will
automatically select PARK when the engine is turned
off.
10. Turn the ignition to the OFF mode.
11. Attach the vehicle to the tow vehicle using a suitable tow bar.
12. Turn the ignition to the ON/RUN mode, but do not start the engine.
13. Release the parking brake.
14. Turn the ignition OFF.

STARTING AND OPERATING 427

NOTE:
•Steps 2 and 3 are requirements that must be met before
pushing the NEUTRAL (N) button, and must continue
to be met until the shift has been completed. If any of
these requirements are not met before pushing the
NEUTRAL (N) button or are no longer met during the
shift, the NEUTRAL (N) indicator light will flash con-
tinuously until all requirements are met or until the
NEUTRAL (N) button is released.
• The ignition must be in the ON/RUN mode for a shift to
take place and for the position indicator lights to be
operable. If the ignition is not in the ON/RUN mode, the
shift will not take place and no position indicator lights
will be on or flashing.
• A flashing NEUTRAL (N) position indicator light indi-
cates that shift requirements have not been met.
• If the vehicle is equipped with air suspension, the engine
should be started and left running for a minimum of 60
seconds (with all the doors closed) at least once every 24
hours. This process allows the air suspension to adjust
the vehicle’s ride height to compensate for temperature
effects.Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage:
1. Bring the vehicle to a complete stop, leaving it con- nected to the tow vehicle.
2. Press and hold the brake pedal.
3. Start the engine. Apply the parking brake. Shift the transmission into NEUTRAL.
4. Using a ballpoint pen or similar object, push and hold the recessed transfer case NEUTRAL (N) button (at the
center of the transfer case switches).
5. When the NEUTRAL (N) indicator light turns off, release the NEUTRAL (N) button.
6. Turn the engine OFF. The transmission will automati- cally select PARK when the engine is turned off.
7. Release the brake pedal.
8. Disconnect vehicle from the tow vehicle.
9. Press and hold the brake pedal.
10. Start the engine.
11. Release the parking brake.

CAUTION!
•When installing the power distribution center cover,
it is important to ensure the cover is properly posi-
tioned and fully latched. Failure to do so may allow
water to get into the power distribution center and
possibly result in an electrical system failure.
(Continued)
CAUTION! (Continued)
•When replacing a blown fuse, it is important 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 overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
