Your trip odometer tells you how far you have driven
since
you last reset it. Press the trip button located next
to the trip odometer, below the fuel gage.
Your Aurora has a tamper resistant odometer.
If you see
silver lines between the numbers, you’ll know someone
has probably tampered with it and the numbers may not
be true.
You
may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total
of the old odometer, then it must be. But if
it can’t, then it’s set at zero and a label must be put on
the driver’s door to show the old mileage reading when
the new odometer was installed.
Tachometer

The tachometer displays the engine speed in revolutions
per minute
(RPM).
If your engine speed equals or exceeds the safe limit for
operation, the message HOT
... REDUCE ENGINE RPM
is displayed on the information center.

Warning Lights, Gages and Indicators
This part describes the warning lights and gages on your
vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is
wrong before
it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could
also save you or
others from injury.
Warning lights come on when there
may be or is a
problem with one
of your vehicle’s functions. As you will
see
in the details on the next few pages, some warning
lights come on briefly when
you start the engine just to let
you know they’re worlung.
If you are familiar with this
section, you should not be alarmed when this happens. Waiting
to do
repairs can be costly -- and even
dangerous.
So please get to know your warning lights
and gages. They‘re a big help.
Your vehicle
also has a Driver Information Center that
works along
with the warning lights and gages. See
“Driver Information Center”
in the Index.
To
turn off messages on the center, except LOW OIL
PRESSURE, LOW BRAKE FLUID, PARK BRAKE
SET and the hot engine warnings, press any button on
the Driver Information Center.
