The transfer case must be shifted into NEUTRAL (N) and the transmission must be
in PARK for recreational towing. The NEUTRAL (N) selection button is adjacent to
the transfer case selector switch. Shifts into and out of transfer case NEUTRAL (N)
can take place with the selector switch in any mode position.
CAUTION!
• DO NOT dolly tow any 4WD vehicle. Internal damage to the transmission or
transfer case will occur if a dolly is used when recreational towing.
• Tow only in a forward direction. Towing this vehicle backwards can cause severe
damage to the transfer case.
• The transmission must be in PARK for recreational towing.
• Before recreational towing, perform the procedure outlined under “Shifting
into NEUTRAL (N)” to be certain that the transfer case is fully in NEUTRAL
(N). Otherwise, internal damage will result.
• Failure to follow these procedures can cause severe transmission and/or
transfer case damage. Damage from improper towing is not covered under the
New Vehicle Limited Warranty.
• Do not use a bumper-mounted clamp-on tow bar on your vehicle. The bumper
face bar will be damaged.
Shifting Into NEUTRAL (N)
Use the following procedure to prepare your vehicle for recreational towing:
1. Bring the vehicle to a complete stop, with the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL.
4. If vehicle is equipped with Quadra-Lift™ air suspension, ensure the vehicle is set
to Normal Ride Height.

• Steps 1 through 4 are requirements that must be met before pressing 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 pressing the NEUTRAL
(N) button or are no longer met during the shift, then 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 Quadra-Lift™ 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.
WARNING!
You or others could be injured or killed 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, even if the
transmission is in PARK. 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.

DIESEL ENGINE BREAK-IN RECOMMENDATIONS
The diesel engine does not require a break-in period due to its construction. Normal
operation is allowed, providing the following recommendations are followed:
• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significant
weight.
NOTE:
Light duty operation such as light trailer towing or no load operation will extend the
time before the engine is at full efficiency. Reduced fuel economy and power may be
seen at this time.
The engine oil installed in the engine at the factory is a high-quality energy conserving
type lubricant. Oil changes should be consistent with anticipated climate conditions
under which vehicle operations will occur. NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.

CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO NOT START the engine
before you drain the water from the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Separator Filter” in “Maintaining
Your Vehicle” in your Diesel Supplement on the DVD for further information.
Extreme Cold Weather
• The engine block heater is a resistance heater installed in the water jacket of the
engine. It requires a 110–115 Volt AC electrical outlet with a grounded, three-wire
extension cord.
• Its use is recommended for environments that routinely fall below -10°F. It should
be used when the vehicle has not been running overnight or longer periods and
should be plugged in two hours prior to start. Its use is required for cold starts with
temperatures under -20°F.
• A 12 Volt heater built into the fuel filter housing aids in preventing fuel gelling. It
is controlled by a built-in thermostat.
• A Diesel Pre-Heat system both improves engine starting and reduces the amount
of white smoke generated by a warming engine.
NOTE:
The engine block heater cord is a factory installed option. If your vehicle is not
equipped, heater cords are available from your authorized MOPAR
®dealer.
Water In Fuel Message
If a Water In Fuel message orindicator appears in the cluster and a chime
sounds five times, the fuel/water separator will need to be drained immediately to
prevent engine damage.
