CONTROLS AND DISPLAY
distance that can be shown on the odometer is
“1 999 999” before it rolls over to zero.
Tachometer
The trip odometer displays how far the vehicle has gone
on a particular trip. The trip odometer will display in miles
on an English speedometer or in kilometers on a metric
speedometer, in one tenth divisions. The maximum distance
that can be shown on the trip odometer is “9999.9”
before it rolls over to zero.
To reset the trip odometer, press and hold the trip reset
button on the speedometer. The numbers will reset to 0
and begin to count new miles/km traveled. This also
resets the trip values in the Driver Information Display.
The trip reset button also toggles all displays between
English and Metric. (See page 37.)
NOTE: The Odometer/Trip Meter comes on when
the door is opened or the key is in the accessory
or ignition position. The Odometer/Trip Meter will
remain on for 3 seconds after the door is closed
or the ignition switch is turned off. This allows
driver and service personnel to read the odometer
without ignition switch being turned on.
Your tachometer measures the engine speed in revolutions-per-minute
(RPM). The tachometer also includes an
engine hour meter and outside air temperature display.
Watching your tachometer is important to driving efficiently.
It will let you match driving speed and gear selection
to the operating range of your engine. If your engine
speed gets too high, you can select a higher gear to lower
the RPM. If your engine speed drops too low, you can
select a lower gear to raise the RPM.
