Under heavy loads, such as when climbing steep
grades, temperatures that exceed the normal oil tem-
perature range for a short period are not unusual. If
the temperature returns to normal when the load de-
creases, there is no problem.
Fuel/Diesel Exhaust Fluid (DEF)
Gauge
For engines that are EPA10-compliant or newer, the
fuel and DEF levels are measured in a dual purpose
fuel/DEF level gauge. See
Fig. 4.11 .
The diesel fuel level is indicated at the top of the
gauge, with a low-fuel warning lamp that illuminates
when the diesel fuel level registers 1/8th of capacity.
The DEF level is indicated in the lightbar on the
lower portion of the gauge. There is a low DEF level
warning lamp that illuminates amber when the DEF
level reaches 10% of capacity. See
Chapter 7 for
details of the DEF gauge functions.
Primary and Secondary Air Pressure
Gauges
WARNING
If air pressure falls below minimum pressure, the
braking ability of the vehicle will be limited. Slow
the vehicle down and bring it to a gradual stop.
Do not attempt to move the vehicle until air pres-
sure has risen above the minimum level. Moving
a vehicle without adequate braking power could
cause an accident resulting in property damage,
personal injury, or death.
Air pressure gauges, as shown in Fig. 4.12 , register
the pressure in the primary and secondary air sys-
tems. The gauges are labeled for the A or B reser-
voir. Normal pressure with the engine running is 100
to 120 psi (689 to 827 kPa) in both systems.
A low-air-pressure warning light and audible alert,
connected to both the primary and secondary sys-
tems, activate when air pressure in either system
drops below approximately 70 psi (483 kPa).
When the engine is started, the warning light and
audible warning remain on until air pressure in both
systems exceeds minimum pressure.
