OPERATING INSTRUCTIONS
2. Tachometer
The tachometer measures the engine speed in revolutions per minute
(RPM).
The RPM detail is also available as a viewable screen in the Driver
Performance Center. Viewing the RPM is accomplished by rotating the
MCS until the Gauges screen is displayed and then selecting Tachometer.
The tachometer is a useful gauge when attempting to drive efficiently. It
will let you match driving speed and gear selection to the operating range
of your engine. If the engine speed gets too high, you can select a higher
gear to lower the RPM. If the engine speed drops too low, you can select
a lower gear to raise the RPM. (Refer to Driving Tips and Techniques
on page 188 for further instruction on driving techniques and using the
tachometer.) To avoid engine damage, do not let the pointer exceed
maximum governed speed.
The tachometer will illuminate a small green light just below the numbers of
the gauge. This is to indicate the engine speed for optimal fuel economy.
3. Fuel Level
The fuel gauge indicates the total (approximate) amount of fuel in the fuel
tank. In addition to indicating empty and full, the gauge also indicates
the fuel level in graduated increments. When the fuel level for the tank is
below
1
/
4
full, a red warning light in the gauge will come on.
This vehicle may be manufactured with a different fuel system and different
draw tube locations. Because of this, and the amount of road camber, it
is recommended that you do not operate your vehicle with less than one
quarter of your truck’s fuel capacity. Allowing the fuel level to go below
one quarter of capacity could result in the lack of fuel to keep the engine
running. In addition, you will want to keep the fuel tanks at least half full to
reduce condensation of moisture in the tanks. This moisture can damage
the engine.
Refer to Refueling on page 209 for more information.
