WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Monox-
ide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury
or death when inhaled.
• Keep Remote Keyless Entry key fobs away from
children. Operation of the Remote Start System,
windows, door locks or other controls could cause
serious injury or death.
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. The recom-
mended viscosity and quality grades are shown under
“Fluids, Lubricants and Genuine Parts”, under “Maintain-
ing Your Vehicle” in this manual. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER BE USED.

Cooling System Tips — Automatic Transmission
To reduce the potential for engine and transmission over-
heating in high ambient temperature conditions, take the
following actions:
• City Driving — When stopped, shift the transmission
into NEUTRAL and increase engine idle speed.
• Highway Driving — Reduce your speed.
• Up Steep Hills — Select a lower transmission gear.
• Air Conditioning — Turn it off temporarily.
NOTE: If the coolant temperature is too high the A/C will
automatically turn off.
Do Not Operate The Engine With Low Oil Pressure
If the low oil pressure warning light turns on while
driving, stop the vehicle and shut down the engine as soon
as possible. A chime will sound when the light turns on.
NOTE: Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is in the
engine. The engine oil level must be checked under the
hood.
CAUTION!
If oil pressure falls to less than normal readings, shut
the engine off immediately. Failure to do so could
result in immediate and severe engine damage.

STARTING AND OPERATING 39

•Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant (anti-
freeze) solution. The use of lower quality water will
reduce the amount of corrosion protection in the engine
cooling system.
NOTE:
• It is the owner’s responsibility to maintain the proper
level of protection against freezing according to the
temperatures occurring in the area where the vehicle is
operated.
• Some vehicles require special tools to add coolant prop-
erly. Failure to fill these systems properly could lead to
severe internal engine damage. If any coolant is needed
to be added to the system, please contact your local
authorized dealer.
• Mixing engine coolant (antifreeze) types is not recom-
mended and can result in cooling system damage. If
HOAT and OAT coolant are mixed in an emergency,
have a authorized dealer drain, flush, and refill with
OAT coolant (conforming to MS.90032) as soon as pos-
sible.Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that the engine coolant
(antifreeze) will return to the radiator from the coolant
expansion bottle.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
• Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is over-
heated. Do not loosen or remove the cap to cool an
overheated engine. Heat causes pressure to build up
in the cooling system. To prevent scalding or injury,
do not remove the pressure cap while the system is
hot or under pressure.
• Do not use a pressure cap other than the one speci-
fied for your vehicle. Personal injury or engine
damage may result.

MAINTAINING YOUR VEHICLE 67

MAINTENANCE SCHEDULE
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 will influence when the “Oil Change
Required” message is displayed. Severe Operating Condi-
tions 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 thanyour authorized dealer, the message can be reset by
referring to the steps described under “Instrument Cluster
Display” in “Understanding Your Instrument Panel” for
further information.
NOTE:
Under no circumstances should oil change inter-
vals 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, and power steering, and fill as needed
• Check function of all interior and exterior lights

tion refer to your Owners Manual.
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 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.
For additional vehicle break-in requirements, refer to
“Trailer Towing” in “Starting And Operating” of the Own-
ers Manual.
Because of the construction of the Cummins turbocharged
diesel engine, engine run-in is enhanced by loaded oper-
ating conditions which allow the engine parts to achieve
final finish and fit during the first 6,000 miles (10 000 km).
