freightliner S2 - Speedometer and Tachometer

Emergency Buzzer
The emergency buzzer sounds during the ignition
sequence and whenever one of the following condi-
tions exists:
•
The engine oil pressure falls below the preset
level which is 6 psi (41 kPa) at 700 rpm, or 18
psi (124 kPa) at 4400 rpm.
•
The air pressure falls below the preset level,
which is 65 psi (448 kPa).
•
The parking brake is set with the vehicle mov-
ing at a speed greater than 2 mph (3 km/h).
•
The coolant temperature rises above 253°F
(123°C) and the check engine and stop engine
lights illuminate. When the coolant temperature
falls below 244° (118°C) the emergency buzzer
and stop engine light will turn off.
NOTE: The check engine light will remain on
until the vehicle is inspected at an authorized
Freightliner service facility.
Speedometer and Tachometer
Speedometer
Three kinds of speedometer faces are available. The
U.S. version of the speedometer registers speed in
both miles per hour (mph) and kilometers per hour
(km/h), with mph in larger numbers. See
Fig. 19.19.
The NAFTA version (not shown) of the speedometer
face reverses this arrangement, with km/h in larger
numbers. The metric-only version (not shown) shows
km/h exclusively.
Tachometer
The tachometer indicates engine speed in revolutions
per minute (rpm) and serves as a guide for shifting
the transmission and keeping the engine in the ap-
propriate rpm range. See
Fig. 19.19.
