Tachometer
The rpm detail is also available as a
viewable screen in the instrumentation
cluster as a virtual gauge. The tachometer
is a useful gauge when attempting to drive
ef
ficiently. 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. To avoid engine damage, do
not let the pointer exceed maximum
governed engine speed. (See your Engine
Operation and Maintenance Manual for
rpm recommendations.)
Digital Gauges
If a gauge has a red zone (representing a
gauge region outside of a components
normal operating range), it is indicated by a
horizontal red line.
Gauges that enter a red zone will enlarge
and turn red. If the gauge value rises into
this zone, this boundary will indicate with a
white line, if it lowers, it indicates with a red
line.
Gauges that stop receiving input from the
systems they monitor
, will display the text
“Data Error” and turn gray, with critical
gauges instead, turning red. Gauges
displaying “Data Error” will stop presenting
values reflecting the systems they monitor.
Optional Gauges
Optional physical gauges will be located to
the right of the Display.
Warning Lights and
Indicators
The instrument panel communicates many
vehicle conditions using warning lights
(also called telltales), indicators, and
audible alarms. Some conditions are
communicated for informational purposes
only – indicators – while warning lights
often require an operator response and are
sometimes accompanied with a popup
(see Popups).
Warning Lights
Introduction
W
arning Lights (Telltales), Indicators and
audible alarms may indicate a system
malfunction. They should be checked
frequently and responded to promptly as
soon as they are noticed. These
indications could save you from a serious
accident. Additionally, gauges may become
visible on the Digital Display and may
change color or brightness to bring the
gauge to the operator's attention.
Warning Lights and Indicators are shown
on the instrument cluster, drawing attention
to the component it monitors. Some of
these indications also show an associated
