²Check the coolant and oil levels frequently.
²Vary throttle position at highway speeds when carry-
ing or towing significant weight.
Because of the construction of the Cummins 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).
CAUTION!
²During the first 500 miles (805 km) your new
vehicle is driven, do not tow a trailer. Doing so
may damage your axles, drivetrain and vehicle.
²Limit your speed to 50 mph (80 km/h) during the
first 500 miles (805 km) of towing.
SAFETY TIPS
Transporting Passengers
This vehicle is designed to carry passengers in the cab
only. For safety reasons, NEVER TRANSPORT PASSEN-
GERS IN THE CARGO AREA.
WARNING!
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed.
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat belts.
Be sure everyone in your vehicle is in a seat and
using a seat belt properly.

Lock Your Vehicle
Always remove the keys from the ignition and lock all
doors when leaving the vehicle unattended, even in your
own driveway or garage. Try to park your vehicle in a
well-lighted area and never invite theft by leaving ar-
ticles of value exposed.
Exhaust Gas
WARNING!
Exhaust gases contain carbon monoxide, a potentially
toxic gas that by itself is colorless and odorless. To
avoid inhaling these gases, the following precautions
should be observed:
²Do not run the engine in a closed garage or in confined
areas any longer than needed to move your vehicle in
or out of the area.
²If it is necessary to sit in a parked vehicle with the
engine running for more than a short period, adjust
your climate control system to force outside air into
the vehicle. Set the blower at high speed and the
controls in any position except OFF or MAX A/C.
²The best protection against carbon monoxide entry
into the vehicle body is a properly maintained engine
exhaust system.
Be aware of changes in the sound of the exhaust system;
exhaust fumes detected inside the vehicle; or damage to
the underside or rear of the vehicle. Have a competent
mechanic inspect the complete exhaust system and adja-
cent body areas for broken, damaged, deteriorated or
mispositioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust system
each time the vehicle is raised for lubrication or oil
change. Replace or adjust as required.

WARNING!
Vehicles and other objects seen in a right side convex
mirror will look smaller and farther away than they
really are. Relying too much on your right side
convex mirror could cause you to collide with an-
other vehicle or other object. Use your inside mirror
when judging the size or distance of a vehicle seen in
the right side convex mirror. Some vehicles will not
have a convex right side mirror.
Exterior Mirrors Folding Feature
All6x9inch exterior mirrors are hinged and may be
moved either forward or rearward to resist damage. The

SEATS
The seating options available in this truck are the result of
extensive customer research and evaluations.
Seats are also a primary part of the Occupant Restraint
(protection) System of the vehicle. They need to be used
properly for safe operation of the vehicle.
WARNING!
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed.
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat belts.
Be sure everyone in your vehicle is in a seat and
using a seat belt properly.
40-20-40 Front Seat
As the name implies, the seat is divided into 3 segments.
The outboard seat portions are each 40% of the total
width of the seat. The back of the center portion (20%)
easily folds down to provide an armrest/center storage
compartment (if equipped).

Each outboard seat is independently adjustable forward
or rearward and is equipped with a back recliner. The
manual forward or rearward seat adjustment handle is
found at the front edge of each seat cushion. Pull up on
the handle and slide the seat to get the most comfortable
position.
WARNING!
Adjusting a seat while the vehicle is moving is
dangerous. The sudden movement of the seat could
cause you to lose control. The seat belt might not be
properly adjusted and you could be injured. Adjust
any seat only while the vehicle is parked.
Reclining Seats
The recliner handle is on the outside of the seat cushion.
Pull up on the handle, as shown, to release the seat back
and adjust for comfort.

WARNING!
You can be seriously, even fatally, injured riding in a
seat with the seatback reclined. Do not ride with the
seatback reclined so that the shoulder belt is no
longer resting against your chest. If you ride in this
position, the shoulder harness will no longer be
restraining you. In a collision you could slide under
the seat belt and receive serious or fatal injuries.
Recline in a seat only when the vehicle is parked.
Adjustable Head Restraints
Head restraints can reduce the risk of neck injury in the
event of impact from the rear. Pull up or push down on
the restraints so that the upper edge is as high as
practical, at least to the level of the ears.To lower the head restraint, push in the button and then
push down on the head restraint.

WARNING!
Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, exhaus-
tion or other physical condition must exercise care
when using the seat heater. It may cause burns even
at low temperatures, especially if used for long
periods of time.
Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This may
cause the seat heater to overheat.
