CONTROLS AT A GLANCE

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.

- 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
• If the light is not on during starting, stays on, or turns on while driving, have the vehicle serviced by an authorized service center immediately.
- 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).
- Transmission Temperature Warning Light
• This light indicates that there is excessive transmission fluid temperature that might occur with severe usage such as trailer towing. If this light turns on, stop the
vehicle and run the engine at idle, with the transmission in NEUTRAL, until the
light turns off. Once the light turns off, you may continue to drive normally.
OIL CHANGE EVIC INDICATOR
Message
•If an “oil change” message (shown as "Change Oil Soon" and "Oil Change Needed")
appears and a single chime sounds, it is time for your next required oil change.
Resetting The Light After Servicing
• Turn the ignition switch to the ON/RUN position (do not start engine).
• Fully depress the accelerator pedal three times within 10 seconds.
• Turn the ignition switch to the OFF/LOCK position.
- Low Coolant Level Indicator Light
• This light indicates low coolant level. If the light turns on while driving, stop the vehicle and shut off the engine as soon as possible.
• We recommend you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
WHAT TO DO IN EMERGENCIES
133
MAINTENANCE SCHEDULE – GASOLINE ENGINE
Your vehicle is equipped with an automatic oil change indicator system. The oil change
indicator system will remind you that it is time to take your vehicle in for scheduled
maintenance.
Based on engine operation conditions, the oil change indicator message will
illuminate. This means that service is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures,
and E85 fuel usage will influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km) since last reset. Have your vehicle
serviced as soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator message after completing
the scheduled oil change. If a scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by referring to the steps
described under “Electronic Vehicle Information Center (EVIC)/Oil Change Re-
quired” in “Understanding Your Instrument Panel” for further information.
NOTE:
Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km)
or twelve months, whichever comes first.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual wear or damage
• Check the fluid levels of the coolant reservoir, brake master cylinder, powersteering (2500/3500 Models Only) and automatic transmission (six-speed only) as
needed
• Check function of all interior and exterior lights

MAINTENANCE SCHEDULE – DIESEL ENGINE
CAUTION!
Failure to perform the required maintenance items may result in damage to the
vehicle.
At Each Stop For Fuel
• Check the engine oil level at least 30 minutes after a fully warmed engine is shut off. Checking the oil level while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when the level is at or below the ADD
or MIN mark.
Once A Month
• Inspect the batteries, and clean and tighten the terminals as required.
• Check the fluid levels of the coolant reservoir, brake master cylinder, and automatic transmission (if equipped), and add as needed.
At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Check the coolant level, hoses, and clamps.
• Lubricate outer tie rod ends.
Inspection and service should also be performed anytime a malfunction is observed
or suspected. Retain all receipts.
Oil Change Indicator System
Your vehicle is equipped with an engine oil change indicator system. This system will
alert you when it is time to change your engine oil by displaying the words “Oil
Change Due” on your Electronic Vehicle Information Center (EVIC). The oil change
reminder will remind the owner to change the engine oil every 15,000 miles or 500
hours, whichever comes first, except for the Chassis Cab models that are using B20
biodiesel, which are 12,500 miles or 400 hours, whichever comes first. Failure to
change the engine oil per the maintenance schedule can result in internal engine
damage.
