oil pressure within 15 seconds of engine start-
up.
6. If the engine does not start after 5 to 10 sec-
onds, especially in very cold weather below 0°F
(–18°C), it could be flooded with too much gaso-
line. Try pushing the throttle pedal all the way to
the floor and holding it there as you hold the key
in the START position for up to 15 seconds
NOTICE
Do not crank the engine for more than 30 sec-
onds at a time. Wait two minutes after each try to
allow the starter to cool. Failure to do so could
cause starter damage.
7. If the vehicle starts briefly but then stops again,
repeat the process. This will clear the excess
gasoline from the engine.
8. Do not race the engine immediately after starting
it. Operate the engine and transmission gently
until the oil warms up and lubricates all of the
moving parts.
MIL Lamp
NOTICE
If the vehicle is continually driven when the MIL
lamp is activated, the emission controls may not
work as well, the vehicle fuel economy may not
be as good, and the engine may not run as
smoothly. This could lead to costly repairs that
may not be covered by the vehicle warranty.
Modifications made to the engine, transmission,
exhaust, intake, or fuel system of the vehicle, or
replacing the original tires with tires that do not
meet the same tire performance criteria, can af-
fect the vehicle's emission controls and can
cause the MIL lamp to activate. Modifications to
these systems could lead to costly repairs not
covered by the vehicle warranty. This could also
result in a failure to pass required emission in-
spection and/or maintenance tests.
When the MIL lamp activates, it can either flash on
and off, or remain on with a constantly illuminated
lamp.

MIL Lamp Flashes
IMPORTANT: If the MIL lamp flashes on and off
while driving the vehicle, the driver should find a
safe place to park and stop the vehicle immedi-
ately. See Fig. 15.3 for an example of the MIL
lamp. The vehicle should be taken to an autho-
rized Freightliner dealer as soon as possible for
service. Continued driving with an illuminated
MIL lamp could damage the emission system
and void the warranty.

Fig. 15.3, MIL Lamp
The MIL lamp illuminates to indicate a fault that af-
fects the emission system; a misfire condition is one
example. Diagnosis and service may be required. To
prevent serious damage to the vehicle, observe the
following guidelines:
•
Reduce vehicle speed.
•
Avoid hard accelerations.
•
Avoid steep uphill grades.
Once the MIL lamp begins flashing, the driver should
find a safe place to stop. Turn the vehicle off, wait at
least 10 seconds, and then restart the vehicle. If the
MIL lamp continues to flash, observe the guidelines
listed above and see a dealer for service as soon as
possible.
MIL Lamp is on Constant (steady)
A constant (steady) MIL lamp indicates that an emis-
sion system malfunction has been detected on the
vehicle. Diagnosis and service may be required. The
following information may correct an emissions sys-
tem malfunction.
