Shifting Into NEUTRAL (N)
Use the following procedure to prepare your vehicle for recreational towing.
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.
1. Bring the vehicle to a complete stop, with the engine running. Firmly apply the parking brake.
2. Shift the transmission to NEUTRAL.
3. Press and hold the brake pedal.
4. Depress the clutch pedal on a manual transmission.
5. If the transfer case is in 4WD AUTO (if equipped), press a selector button or rotate the selector switch to shift the transfer case into the 2WD or 4WD LOCK position.
• With manual shift transfer case, shift the transfer case lever into NEUTRAL (N).
• With electronic shift transfer case, press 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 pressed using a ballpoint pen or similar
object. Other models have a rectangular NEUTRAL switch, below the rotary
transfer case control knob. The NEUTRAL (N) indicator light will blink while the
shift is in progress. The light will stop blinking (stay on solid) 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.
6. Release the parking brake.
7. Shift the transmission into REVERSE.
8. Release the brake pedal (and clutch pedal on manual transmissions) for five seconds and ensure that there is no vehicle movement.
9. Repeat steps 7 and 8 with automatic transmission in DRIVE or manual transmis- sion in first gear.
10. Shift the transmission to NEUTRAL. Firmly apply the parking brake. Turn OFF the engine. For vehicles with Keyless Enter-N-Go™, press and hold the ENGINE
START/STOP button until the engine shuts off.

NOTE:
A delay of the start-up can be as long as five seconds under very cold conditions. The
"Wait to Start" telltale will be illuminated during the pre-heat process and the start
will commence upon the telltale going out.
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 theengine. 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.
Refer to “Draining Fuel Water Separator” in this guide for draining instructions or see
your dealer.

DIESEL ENGINE BREAK-IN RECOMMENDATIONS
The Cummins®turbocharged diesel engine does not require a break-in period due to
its construction. Normal operation is allowed, providing the following recommenda-
tions 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.
Because of the construction of the Cummins
®turbocharged diesel engine, engine
run-in is enhanced by loaded operating conditions which allow the engine parts to
achieve final finish and fit during the first 6,000 miles (10 000 km).
DIESEL ENGINE STARTING PROCEDURES
Engine Block Heater
For ambient temperatures below 0°F (-18°C), engine block heater usage is recom-
mended.
For ambient temperatures below –20°F (-29°C), engine block heater usage is required.
The engine block heater cord is routed under the hood to the right side and can be
located just behind the grille near the headlamp.
Connect the heater cord to a ground-fault interrupter protected 110–115 volt AC
electrical outlet with a grounded, three-wire extension cord.
NOTE:
The block heater will require 110 volts AC and 6.5 amps to activate the heater element.
The block heater must be plugged in at least one hour to have an adequate warming
effect on the coolant.

WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned by
steam or boiling coolant.
BRAKE- Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking
brake application. If the brake light turns on it may indicate that the parking brake is
applied, that the brake fluid level is low, or that there is a problem with the anti-lock
brake system reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid
level is at the full mark on the master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS)/Electronic Stability Control (ESC)
system. In this case, the light will remain on until the condition has been corrected.
If the problem is related to the brake booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity in the event of a failure to
a portion of the hydraulic system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a specified level. The light will remain on
until the cause is corrected.
Vehicles equipped with the Anti-Lock Brake System (ABS), are also equipped with
Electronic Brake Force Distribution (EBD). In the event of an EBD failure, the Brake
Warning Light will turn on along with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be checked by turning the ignition switch
from the OFF position to the ON/RUN position. The light should illuminate for
approximately two seconds. The light should then turn off unless the parking brake
is applied or a brake fault is detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
The light also will turn on when the parking brake is applied with the ignition switch
in the ON/RUN position.
NOTE:
This light shows only that the parking brake is applied. It does not show the degree
of brake application.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system
may have failed. It will take longer to stop the vehicle. You could have a collision.
Have the vehicle checked immediately.

- Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the
ignition switch is turned to the ON/RUN position and may stay on for as long as four
seconds.
If the ABS light remains on or turns on while driving, it indicates that the Anti-Lock
portion of the brake system is not functioning and that service is required. However, the
conventional brake system will continue to operate normally if the BRAKE warning light
is not on.
If the ABS light is on, the brake system should be serviced as soon as possible to
restore the benefits of Anti-Lock brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have the light inspected by an
authorized dealer.
- Electronic Throttle Control (ETC) Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system.
If a problem is detected, the light will come on while the engine is running. Cycle the
ignition when the vehicle has completely stopped and the shift lever is placed in the
PARK position; the light should turn off.
If the light remains lit with the engine running, your vehicle will usually be drivable;
however, see an authorized service center immediately. If the light is flashing when the
engine is running, immediate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and your vehicle may require towing.
- Air Bag Warning Light
This light will turn on for four to eight seconds as a bulb check when the ignition
switch is first turned to the ON/RUN position. If the light is either not on during
starting, stays on, or turns on while driving, have the system inspected at an
authorized dealer as soon as possible. Refer to “Occupant Restraints” in “Things To
Know Before Starting Your Vehicle” of your Owner’s Manual for further information.
NOTE:
The Air Bag System is designed to be maintenance free.
- SERV (Service) 4WD Indicator Light
The SERV 4WD light monitors the electric shift four-wheel drive system. If the SERV
4WD light stays on or comes on during driving, it means that the four-wheel drive
system is not functioning properly and that service is required.
For vehicles equipped with a premium cluster this indicator will display in the
Electronic Vehicle Information Center (EVIC).
