WARNING!
•An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchorage position directly
behind the child seat to secure a child restraint top
tether strap.
• If your vehicle is equipped with a split rear seat,
make sure the tether strap does not slip into the
opening between the seatbacks as you remove
slack in the strap.
Transporting Pets
Air Bags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision.
Pets should be restrained in the rear seat in pet harnesses
or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri-
mental and should be avoided.
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. For
the recommended viscosity and quality grades, refer to
“Maintenance Procedures” in “Maintaining Your Ve-
hicle”.
108 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
Page 111 of 546

CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE: A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and
not interpreted as a problem.
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 recommen-
dations 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 indica-
tors.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carry-
ing 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
Owners Manual.
Because of the construction of the Cummins® turbo-
charged diesel engine, engine run-in is enhanced by

•Transmission Temperature Warning Telltale
This telltale indicates that the transmission
fluid temperature is running hot. This may
occur with severe usage, such as trailer
towing. If this telltale turns on, safely pull
over and stop the vehicle. Then, shift the transmis-
sion into NEUTRAL and run the engine at idle or
faster until the light turns off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illumi-
nated you could cause the fluid to boil over, come in
contact with hot engine or exhaust components and
cause a fire.
•Air Suspension Payload Protection Telltale — If
Equipped This telltale will turn on to indicate that the
maximum payload may have been ex-
ceeded or load leveling cannot be achieved
at its current ride height.
Protection Mode will automatically be selected in
order to “protect” the air suspension system, air
suspension adjustment is limited due to payload.

•Windshield Washer Fluid Low Indicator
This telltale will turn on to indicate the wind-
shield washer fluid is low.
• Low Coolant Level Indicator
This telltale will turn on to indicate the vehicle
coolant level is low.
• Transmission Temperature Warning Telltale
This telltale indicates that the transmission
fluid temperature is running hot. This may
occur with severe usage, such as trailer towing.
If this telltale turns on, safely pull over and
stop the vehicle. Then, shift the transmission into NEU-
TRAL and run the engine at idle or faster until the light
turns off.CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illumi-
nated you could cause the fluid to boil over, come in
contact with hot engine or exhaust components and
cause a fire.

CAUTION!(Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals, such as every fuel stop. The best time to check the engine oil level is about five
minutes after a fully warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
