The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed so it will be
ready to warn you if there is a problem.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read 210 F (100 C) or less. If you are pulling a
load or going up hills, it is normal for the temperature to
fluctuate and approach the 250 F (122 C) mark. If the
gage reaches the 260 F (125 C) mark, it indicates that
the cooling system is working beyond its capacity.
The “Problems on the Road,” section of this manual
shows what to do. See “Engine Overheating” in
the Index.
Transmission Temperature Gage
(If Equipped)
If your vehicle has a heavy
duty automatic
transmission, you will have
a transmission temperature
gage.
When your ignition is on, the gage shows the
temperature of the transmission fluid. The normal
operating range is from 100 F (38 C) to about
265 F (130 C).
