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.

BRAKE- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or the parking brake is applied. If the light is on and the parking brake is not applied,
it indicates a possible brake hydraulic malfunction, brake booster problem or an
Anti-Lock Brake System problem.
• Please have your vehicle serviced immediately.
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.
- Malfunction Indicator Light (MIL)
• Certain conditions, such as a loose or missing gas cap, poor fuel quality, etc., may illuminate the MIL after engine start. The vehicle should be serviced if the light
stays on through several typical driving cycles. In most situations, the vehicle will
drive normally and not require towing.
• If the MIL flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic converter damage. We
recommend you do not operate the vehicle. Have the vehicle serviced immediately.
- Electronic Stability Control (ESC) OFF Indicator Light
• If the ESC OFF indicator light comes on when the Electronic Stability Control (ESC) is off.
- Charging System Light
