WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Axle Lubricant and Trailer Towing
2500/3500 Models
•
The Axles on 2500/3500 Modelsare trailer tow ready
andDO NOT REQUIREany special axle lubes or
additives.
Trailer Towing Recommendations
•
All trailer hitches should be professionally installed on
your vehicle.
•Safety chains must always be used between your
vehicle and trailer.
•Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury. An electrically–actuated electric trailer
brake controller is recommended.
•Trailer brakes are recommended for trailers over 1000
lbs (454 kg) and are required for trailers in excess of
2,000 lbs (907 kg)
•Use an approved wiring harness connector on the
trailer. Standard equipment on all RAM pickup mod-
els provides a 4-way trailer tow connector located

during the 1 second time, then all of the mode position
indicator lights will flash continuously until all require-
ments are met or until the Neutral (N) button is released.
NOTE:The ignition key must be ON for a shift to take
place and for the position indicator lights to be operable.
If the key is not ON, the shift will not take place and no
position indicator lights will be on or flashing.
NOTE:Flashing neutral (N) position indicator light
indicates that shift requirements have not been met.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging the
parking brake. The transfer case Neutral (N) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
despite the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.

316 WHAT TO DO IN EMERGENCIES

Clutch Hydraulic System
The clutch hydraulic system is a sealed maintenance-free
system. In the event of leakage or other malfunction, the
system must be replaced.
Rear Axle And 4x4 Front Driving Axle Fluid Level
For Model 9.25 Front Axles and 10.5”/11.5” Rear Axles
refer to Recommended Fluids, Lubricants and Genuine
Parts for the correct lubricant type. For normal service,
periodic fluid level checks are not required. When the
vehicle is serviced for other reasons, the exterior surfaces
of the axle assembly should be inspected.
When checking the fluid level, the vehicle should be in a
level position. The fluid level should be 1/4” ± 1/4” (6.4
mm ± 6.4 mm) below the fill hole on the 9.25” Front Axle.
The fluid level should be 3/4” ± 1/4” (19 mm ± 6.4 mm)
below the fill hole on all 10.5” and 1/4” ± 1/4” (6.4 mm
± 6.4 mm) on 11.5” Rear Axles.
Drain And Refill
Vehicles operated in normal service do not have regularly
scheduled oil changes. If fluid has become contaminated
with water or subjected to severe service, follow the
recommended change intervals in Maintenance Schedule
“B” in Section 8 of this manual.
Lubricant Selection
Refer to Recommended Fluids, Lubricants and Genuine
Parts for the correct lubricant type.
NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
Limited-Slip Differentialsin vehicles equipped with
10.5”/11.5” AxlesDO NOT REQUIREany limited slip
oil additive (friction modifiers).

2. Use specified fuses only.
3. Always properly reinstall the cover.
VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
•Disconnect the Ignition-Off Draw fuse (I.O.D.) fuse
located in the Fuse and Relay Center, located in the
engine compartment. The I.O.D. cavity includes a
snap-in retainer that allows the fuse to be discon-
nected, without removing it from the fuse block.
•The electronic shift transfer case should be placed in
the 4HI mode and kept in this position to minimize the
battery drain.
•As an alternative to the above steps you may, discon-
nect the negative cables from both batteries.
