Recreational Towing – Four-Wheel Drive Models
NOTE:
Both the manual shift and electronic shift transfer cases must be shifted into
NEUTRAL (N) for recreational towing. Automatic transmissions must be shifted into
PARK for recreational towing. Manual transmissions must be placed in gear (NOT in
NEUTRAL) for recreational towing. Refer to the following for the proper transfer case
NEUTRAL (N) shifting procedure for your vehicle.
CAUTION!
• Towing with the rear wheels on the ground will cause severe transmissiondamage. Damage from improper towing is not covered under the New Vehicle
Limited Warranty.
• Do not disconnect the driveshaft because fluid may leak from the transmission,
causing damage to internal parts.
• Front or rear wheel lifts should not be used. Internal damage to the transmis-
sion or transfer case will occur if a front or rear wheel lift is used when
recreational towing.
• Tow only in the forward direction. Towing this vehicle backwards can cause
severe damage to the transfer case.
• Automatic transmissions must be placed in the PARK position for recreational
towing.
• Manual transmissions must be placed in gear (not in Neutral) for recreational
towing.
• Before recreational towing, perform the procedure outlined under “Shifting
Into NEUTRAL” to be certain that the transfer case is fully in NEUTRAL.
Otherwise, internal damage will result.
• Towing this vehicle in violation of the above requirements can cause severe
transmission and/or transfer case damage. Damage from improper towing is
not covered under the New Vehicle Limited Warranty.

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 recom-
mendations 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 recommended.
• 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.
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.

Cold Start Procedure
• Turn the ignition switch to the ON position. If the Wait To Start
light appears
in the cluster, wait for the light to turn off before starting.
• In extremely cold weather below 0°F (-18°C) it may be beneficial to cycle the manifold heaters twice before attempting to start the engine. This can be
accomplished by turning the ignition OFF for at least five seconds and then back
ON after the “Wait To Start Light” has turned off, but before the engine is started.
However, excessive cycling of the manifold heaters will result in damage to the
heater elements or reduced battery voltage.
• Refer to the Owner's Manual Diesel Supplement on the DVD for further details.
Engine Idling
• Avoid prolonged engine idling. Long periods of idling may be harmful to your engine because combustion chamber temperatures can drop so low that the fuel
may not burn completely.
• Incomplete combustion allows carbon and varnish to form on piston rings, engine valves, and injector nozzles. Also, the unburned fuel can enter the crankcase,
diluting the oil and causing rapid wear to the engine.
• If the engine is allowed to idle, under some conditions the idle speed may increase to 900 RPM then return to normal idle speed. This is normal operation.
WARNING!
Remember to disconnect the cord before driving. Damage to the 110–115 volt
electrical cord could cause electrocution.
DIESEL EXHAUST BRAKE (ENGINE BRAKING)
• The exhaust brake feature will only function when the driver presses the exhaustbrake switch.
• The switch is located on the switch bank below the audio system.
• Your vehicle is also equipped with the Smart Brake feature.
• This feature will automatically provide a variable amount of engine braking in an attempt to maintain a constant vehicle speed.
• The Smart Brake is activated by pressing the exhaust brake switch twice. The first press activate the full strength brake, second press activates the Smart Brake and
third press turns the brake off.
• The Smart Brake target vehicle speed is set when either the vehicle brake or the throttle pedal is released.
• Exhaust braking is most effective when the engine RPM is higher.
NOTE:
For optimum braking power, it is recommended to use the exhaust brake while in
TOW/HAUL mode.
