Diesel Particulate Filter (If Equipped)
Illuminates when the soot level in the
diesel particulate filter has reached a point
where it requires operator assistance. See
Diesel Particulate Filter
(page 109).
Direction Indicator Illuminates when you switch on
the left or right direction
indicator or when you switch on
the hazard warning flashers. If the
indicators stay on or flash faster, check for
a burned out bulb.
Door Ajar Displays when the ignition is on
and any door is not completely
closed.
Electronic Locking Differential
(If
Equipped) Illuminates when using the
electronic locking differential.
Engine Oil Pressure If it illuminates with the engine
running, or when you are driving,
this indicates a malfunction.
Stop your vehicle as soon as it is safe to
do so and switch off the engine. Check the
engine oil level.
Note: Do not resume your journey if it
illuminates despite the level being correct.
Have the system checked by an authorized
dealer immediately.
Exhaust Brake On
(If Equipped) The exhaust brake indicator light
illuminates when you switch the
exhaust brake on. Fasten Seatbelt Illuminates and a tone sounds
to remind you to fasten your
seatbelt.
High Beam Illuminates when you switch on
the high beam headlamps. It
flashes when you use the
headlamp flasher.
Hydromax Illuminates to indicate normal
hydromax booster reserve
system activation when the
engine is off and the service brake pedal is
applied. This light may also illuminate
momentarily if the engine is running and
the driver turns the steering wheel fully in
one direction while braking. If the light
remains on while the engine is running, this
indicates inadequate hydraulic booster
pressure or reserve pump system failure.
Stop the vehicle as soon as possible and
seek service immediately by your
authorized dealer.
Low Fuel Level
(If Equipped) Illuminates when the fuel level
is low or the fuel tank is nearly
empty. Refuel as soon as
possible.
Parking Brake Warning Illuminates briefly when you
switch the ignition to the on
position (with the engine off). It
also illuminates when you apply the
parking brake. If the park brake lamp does
not illuminate at these times, seek service
immediately. Vehicles equipped with the

Engine starting (with parking brake applied)
Check the gauge (diesel engine) or indicator light (gasoline
engine) to verify the alternator is charging.
Voltmeter
Inspect for excessive free play in the steering linkages. The
steering wheel should have less than 2 in (5 cm) of free play
at its rim.
Steering linkage free play
Verify the parking brake holds the vehicle by gently trying to
pull forward with the parking brake applied.
Parking brake
Verify operation using the following procedure. Chock the
wheels, if necessary. Push in the parking brake and, on
tractors, push in the tractor parking brake knob:
Air brakes
1. Verify the air compressor or governor cutout pressure is
approximately 120 psi (827 kPa).
2. Turn off the engine, and then turn the key back to the on
position (without starting the engine).
3. Without the brake pedal applied, note the air pressure drop
for one minute. It should be less than 2 psi (14 kPa) for single
vehicles and
3 psi (21 kPa) for combination vehicles.
4. Press and hold the brake pedal with
90 psi (621 kPa) or
more. Make sure there is no more than a 3 psi (21 kPa) per
minute leak for single vehicles and a 4 psi (28 kPa) minute
leak for combination vehicles.
5. Pump the brake pedal to deplete the system of air pressure.
The warning light and tone should turn on at 57 psi (393 kPa).
6. Pump the brake pedal and make sure the parking brake
and trailer parking brake knobs pop out at
20 psi (138 kPa)
or higher.
Verify that the fluid level is in the proper operating range. See
Automatic Transmission Fluid Check
(page 203).
Automatic transmission

2. Release the wiper blade lock (A) and
separate the wiper blade from the
wiper arm.
3. Install in the reverse order.
Note: Make sure that the wiper blade locks
into place. Lower the wiper arm and blade
back on the windshield. The wiper arms will
automatically return to their normal position
when you turn the ignition on.
• Replace wiper blades at least once per
year for optimum performance.
• You can improve poor wiper quality by
cleaning the wiper blades and the
windshield.
ADJUSTING THE HEADLAMPS
Vertical Aim Adjustment
The headlamps on your vehicle are
properly aimed at the assembly plant. If
your vehicle has been in an accident, the
alignment of your headlamps should be
checked by your authorized dealer. Headlamp Aiming Target
8 feet (2.4 meters)
A
Center height of lamp to ground
B
25 feet (7.6 meters)
C
Horizontal reference line
D
Vertical Aim Adjustment Procedure
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 ft (7.6 m) away.
2. Measure the height of the headlamp bulb center from the ground and mark
an
8 ft (2.4 m) horizontal reference line
on the vertical wall or screen at this
height.
Note: To see a clearer light pattern for
adjusting, you may want to block the light
from one headlamp while adjusting the
other.
3. Turn on the low beam headlamps to illuminate the wall or screen and open
the hood.
