The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
— Vehicle Security Warning Light — If Equipped
This light will flash at a fast rate for approximately 15
seconds when the vehicle security alarm is arming, and
then will flash slowly until the vehicle is disarmed.
— Engine Coolant Temperature Warning Light
This light warns of an overheated engine condition. If the
engine coolant temperature is too high, this indicator will
illuminate and a single chime will sound. If the tempera-
ture reaches the upper limit, a continuous chime will be
sound for four minutes or until the engine is able to cool:
whichever comes first.
If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift
the transmission into NEUTRAL and idle the vehicle. If the
temperature reading does not return to normal, turn the
engine off immediately and call for service. Refer to “If
Your Engine Overheats” in “In Case Of Emergency” for
further information.
— Battery Charge Warning Light
This light illuminates when the battery is not charging
properly. If it stays on while the engine is running, there
may be a malfunction with the charging system. Contact
your authorized dealer as soon as possible.
This indicates a possible problem with the electrical system
or a related component.
— Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light
turns on while driving, stop the vehicle and shut off the
engine as soon as possible. A chime will sound when this
light turns on.
Do not operate the vehicle until the cause is corrected. This
light does not indicate how much oil is in the engine. The
engine oil level must be checked under the hood.
— Electronic Throttle Control (ETC) Warning
Light
This light informs you of a problem with the Electronic
Throttle Control (ETC) system. If a problem is detected
while the vehicle is running, the light will either stay on or
flash depending on the nature of the problem. Cycle the
ignition when the vehicle is safely and completely stopped

WARNING!
If you continue operating the vehicle when the Trans-
mission Temperature Warning Light is illuminated you
could cause the fluid to boil over, come in contact with
hot engine or exhaust components and cause a fire.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
— Rear Fog Indicator — If Equipped
This indicator will illuminate when the rear fog lights are
on.
— Air Suspension Payload Protection Indicator
Light — If Equipped
This telltale will turn on to indicate that the maximum
payload may have been exceeded 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.
— TOW/HAUL Indicator Light
This light will illuminate when TOW/HAUL mode is
selected.
— Cargo Light — If Equipped
The cargo light will illuminate when the cargo light is
activated by pushing the cargo light button on the head-
light switch.
— Air Suspension Off-Road 1 Indicator Light —
If Equipped
This light will illuminate when the air suspension system is
set to the Off-Road 1 setting. For further information, refer
to “Air Suspension System” in “Starting And Operating.”
— Air Suspension Off-Road 2 Indicator Light —
If Equipped
This light will illuminate when the air suspension system is
set to the Off-Road 2 setting. For further information, refer
to “Air Suspension System” in “Starting And Operating”.

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 recom-
mended viscosity and quality grades, refer to “Fluids And
Lubricants” in “Technical Specifications”.
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. Please check your oil level with
the engine oil indicator often during the break in period.
Add oil as required.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave the trans-
mission in PARK.
The foot operated parking brake is located below the lower
left corner of the instrument panel. To apply the park
brake, firmly push the park brake pedal fully. To release the
parking brake, pull the parking brake release handle.

Is it a straight descent? Is there plenty of distance at the
base of the hill to regain control if the vehicle descends
too fast? If you feel confident in your ability to proceed
then make sure you are in 4LO (Low Range) with the
transmission in first gear (manually select first gear on
automatic transmissions) and proceed with caution.
Allow engine braking to control the descent and apply
your brakes if necessary, but do not allow the tires to
lock.
WARNING!
Do not descend a steep grade in NEUTRAL. Use
vehicle brakes in conjunction with engine braking.
Descending a grade too fast could cause you to lose
control and be seriously injured or killed.
• Driving Across An Incline – If at all possible avoid
driving across an incline. If it is necessary, know your
vehicle’s abilities. Driving across an incline places more
weight on the down hill wheels, which increases the
possibilities of a down hill slide or rollover. Make sure
the surface has good traction with firm and stable soils.
If possible transverse the incline at an angle heading
slightly up or down.
WARNING!
Driving across an incline increases the risk of a roll-
over, which may result in severe injury.
• If You Stall Or Begin To Lose Headway – If you stall or
begin to lose headway while climbing a steep hill, allow
your vehicle to come to a stop and immediately apply
the brake. Restart the engine and shift into REVERSE.
Back slowly down the hill allowing the compression
braking of the engine and transmission to help regulate
your speed. If the brakes are required to control vehicle
speed, apply them lightly and avoid locking or skidding
the tires.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and
rolling the vehicle, which may result in severe injury.
Always back carefully straight down a hill in RE-
VERSE. Never back down a hill in NEUTRAL using
only the vehicle brakes. Never drive diagonally across
a hill, always drive straight up or down.

Severe Duty All Models
NOTE:Change Engine Oil at 4,000 miles (6,500 km) or 350
hours of engine run time if the vehicle is operated in a
dusty and off road environment or is operated predomi-
nantly at idle, or only very low engine RPM’s. This type of
vehicle use is considered Severe Duty.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular wear,
even if it occurs before the oil indicator system turns on.
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering (2500/3500 Models
Only) and automatic transmission (six-speed only) and
fill as needed
• Check function of all interior and exterior lightsMaintenance Plan
Required Maintenance
Refer to the Maintenance Plan on the following pages for
required maintenance.
At Every Oil Change Interval As Indicated By Oil
Change Indicator System:
•Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular
wear, even if it occurs before the oil indicator
system turns on.
• Inspect battery and clean and tighten terminals as
required.
• Inspect automatic transmission fluid if equipped
with dipstick.
• Inspect brake pads, shoes, rotors, drums, hoses and
park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or
off-road conditions.
• Lube the front drive shaft fitting (2500/3500 (4x4)
models only).
