Engine starting (parking brake applied)
Starting the engine:Verify the parking brake is set. Depress the
clutch (if equipped with a manual
transmission) and verify the transmission is in
neutral. Vehicles equipped with an automatic
transmission should be in N (Neutral) or P
(Park) if equipped with a Park position.
When the WAIT TO START indicator light in
the instrument cluster turns off, turn the key
to START.
Oil pressure builds:Make sure engine oil pressure is building to
normal operating range.
Air chime sounds (if
equipped with air
compressor):The low air pressure warning chime should
sound immediately after the engine starts but
before the compressor has built up pressure.
The low air pressure warning chime should
stop when the air pressure reaches 70 psi
(483 kPa) (or more). Let the air pressure
build to governed cut-out pressure, which
should occur between 115–130 psi
(793–896 kPa).
Accelerator:Depress the accelerator and verify that it
operates smoothly without any binding or
irregular feel. Remove your foot from the
pedal and make sure the engine returns to idle
speed immediately.
Ammeter/Voltmeter:Check the gauge to see if the alternator is
charging.
Steering linkage
free play:Check for excessive free play in the steering
linkages. The steering wheel should have less
than two inches (five cm) of free play at rim
of steering wheel.
Hydraulic brake
check:When the engine is off, the pump will turn on
if the brake pedal is applied, or if the ignition
is turned to the ON position.

Engine starting (parking brake applied)
Parking brake:Check that the parking brake will hold the
vehicle by gently trying to pull forward with
the parking brake applied.
Air brake check:Check the air brakes in the following manner
(Chock the wheels, if necessary. Push in the
parking brake and on tractors, also push in the
tractor parking brake knob):
1. Check the air compressor or governor
cut-out pressure (approximately 120 psi
[827 kPa]).
2. Cut-off the engine and turn the key back to
ON, 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 vehicle and
3 psi (21 kPa) for combination vehicles.
4. Depress and hold the brake pedal with
90 psi (621 kPa) or more and make sure there
is no more than a 3 psi (21 kPa) per minute
leak. For combination vehicles, no more than
4 psi (28 kPa) per minute.
5. Pump the brake pedal to deplete the system
air pressure. The warning light and chime
should activate 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.
Automatic
transmission fluid:With the engine idling at normal operating
temperature and the parking brake applied,
check the automatic transmission fluid. If fluid
needs to be added, place the transmission in
the appropriate gear as specified in the
transmission operator’s manual and refer to
Transmission fluidin theMaintenance and
Specificationschapter.

WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, have the
respective system inspected immediately.
Some of the warning lights shown are optional based on vehicle
equipment; your vehicle may not have some of the warning lights shown
in this section.
Service engine soon:If this light
illuminates while driving, it is a
possible indication that one of the
engine’s emission control systems
has failed.
Check suspension (if equipped):
Illuminates when the air suspension
dump switch has been activated.

Stop engine:This light is used in
conjunction with the electronic
engine control. When illuminated,
the STOP ENGINE lamp indicates the need tostopthe engine as soon
as it can be safely done.
If the STOP ENGINE lamp begins flashing automatic engine
shutdown may take place in as little as 20 seconds.
In the event of engine shutdown, make sure the vehicle is safely
off the road and the problem is remedied prior to returning to
the road. Failure to remove the vehicle from the road could result in
an accident, causing serious injury or death.
Refer to your engine operator’s manual for specific information regarding
this feature.
If the engine shuts down, it can be restarted and operated for
30 seconds at a time or until the problem is corrected. For more
information, refer toEngine automatic shutdown warning light or
chimein theDrivingchapter of this owner guide and/or your engine
operator’s manual.
Drivers of electronically controlled engines should know the
extent of warning engine shutdown system before operating the
vehicle.
Brake reserve system warning:
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 safely as soon as possible and seek service immediately.

Charging system:Illuminates when
the battery is not charging properly.
Diesel particulate filter
(Cummins engines only):
Illuminates if the soot in the DPF
has reached a level where it
requires operator assistance. Refer
toDiesel Particulate Filterin the
Maintenance and Specificationschapter and your engine operator’s
manual, for more details.
Turn signal:Illuminates when the
left or right turn signal or the
hazard lights are turned on. If the
indicators stay on or flash faster, check for a burned out bulb.
High beams:Illuminates when the
high beam headlamps are turned on.
Safety belt warning chime:Sounds when the key is in the ignition and
the driver’s safety belt is not fastened.
Key-in-ignition warning chime:Sounds when the key is left in the
ignition in the OFF/LOCK or ACC position and the driver’s door is
opened.
Headlamps on warning chime:Sounds when the headlamps or parking
lamps are on, the ignition is off (and the key is not in the ignition) and
the driver’s door is opened.

light illuminates and the warning
chime sounds for 6 seconds every
30 seconds, repeating for
approximately 5 minutes or until
safety belt is buckled.
The driver’s safety belt is buckled

The following are reasons most often given for not wearing safety belts:
(All statistics based on U.S. data)
Reasons given... Consider...
“Crashes are rare
events”36700 crashes occur every day.The more we
drive, the more we are exposed to “rare” events,
even for good drivers.1in4ofuswillbe
seriously injured in a crash during our
lifetime.
“I’m not going far”3of4fatal crashes occur within25miles of home.
“Belts are
uncomfortable”We design our safety belts to enhance comfort. If
you are uncomfortable - try different positions for
the safety belt upper anchorage and seatback
which should be as upright as possible; this can
improve comfort.
“I was in a hurry”Prime time for an accident.Belt-Minder
reminds us to take a few seconds to buckle up.
“Seat belts don’t
work”Safety belts,when used properly,reduce risk of
deathto front seat occupants by45% in cars,
and by60% in light trucks.
