air suspension Ram 2500 2016 Service Manual

NOTE:
•When recreational towing your vehicle, always follow
applicable state and provincial laws. Contact state and
provincial Highway Safety offices for additional de-
tails.
• Vehicles equipped with air suspension must be placed
in Transport mode before tying them down (from the
body) on a trailer or flatbed truck. Refer to “Air
Suspension – If Equipped” for more information. If the
vehicle cannot be placed in Transport mode (for ex-
ample, engine will not run), tie-downs must be fas-
tened to the axles (not to the body). Failure to follow
these instructions 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
allowed ONLYif 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. Firmly apply the parking brake. Place automatic trans- mission in PARK, manual transmission in gear (not in
NEUTRAL).

STARTING AND OPERATING 717

WARNING!(Continued)
the parking brake. The transfer case NEUTRAL (N)
position disengages both the front and rear drive
shaft from the powertrain, and will allow the vehicle
to roll, even if the automatic transmission is in PARK
(or manual transmission is in gear). The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL (N) before
recreational towing to prevent damage to internal
parts.
1. Bring the vehicle to a complete stop, with the engine running. Firmly apply the parking brake. 2. Shift the transmission to NEUTRAL.
NOTE:
If vehicle is equipped with air suspension, ensure
the vehicle is set to Normal Ride Height.
3. Press and hold the brake pedal.
4. Depress the clutch pedal on a manual transmission.
5. With manual shift transfer case, shift the transfer case lever into NEUTRAL (N).
• With electronic shift transfer case, push and hold the
transfer case NEUTRAL (N) button. Some models
have a small, recessed “N” button (at the center of
the transfer case switches) that must be pushed using
a ballpoint pen or similar object. Other models have
a rectangular NEUTRAL switch, below the rotary
transfer case control knob. The NEUTRAL (N) indi-
cator light will blink while the shift is in progress.
The light will stop blinking (stay on solid) when the
720 STARTING AND OPERATING

during the shift, the NEUTRAL (N) indicator light will
flash continuously until all requirements are met or
until the NEUTRAL (N) button is released.
• The ignition switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing.
• A flashing NEUTRAL (N) position indicator light
indicates 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 mini-
mum 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 com-
pensate 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. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine. Shift the transmission into NEU- TRAL. Depress the clutch pedal on a manual trans-
mission.
• With manual shift transfer case, shift the transfer
case lever to the desired position.
• With electronic shift transfer case with rotary selector
switch, push and hold the transfer case NEUTRAL
(N) button until the NEUTRAL (N) indicator light
turns off. After the NEUTRAL (N) indicator light
turns off, release the NEUTRAL (N) button. After the
722 STARTING AND OPERATING

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service. If the trans-
mission and drivetrain are operable, disabled vehicles
may also be towed as described under “Recreational
Towing” in the “Starting And Operating” section.NOTE:
Vehicles equipped with air suspension must be
placed in Transport mode, before tying them down (from
the body) on a trailer or flatbed truck. Refer to Air
Suspension inStarting And Operating for more infor-
mation. If the vehicle cannot be placed in Transport mode
(for example, engine will not run), tie-downs must be
fastened to the axles (not to the body). Failure to follow
these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.
