Service Vehicle Soon Light
The SERVICE VEHICLE
SOON light will come on if
there are certain
non-emission related
vehicle problems.
These problems may not be obvious and may affect
vehicle performance or durability. Consult your
dealership for necessary repairs to maintain top vehicle
performance. The light will come on briey when the
ignition is turned on to show that it is working properly.
Fuel Gage
The fuel gage indicates about how much fuel is left in
the fuel tank when the ignition is on. When the indicator
nears empty, there is still a little fuel left, but you
should get more fuel soon.
Here are four things that some owners ask about. All
these things are normal and do not indicate that
anything is wrong with the fuel gage:
At the gas station, the pump shuts off before the
gage reads full.
It takes more, or less, fuel to ll up than the gage
reads. For example, the gage reads half full, but
it took more, or less, than half of the tank’s capacity
to ll it.
The gage pointer may move while cornering,
braking or accelerating.
The gage may not indicate empty when the ignition
is turned off.

Low Fuel Warning Light
If the vehicle’s fuel is low, a circular light on the
instrument panel cluster will come on and a chime will
sound periodically until fuel is added to the fuel tank.
It will also come on for a few seconds when the ignition
is turned on as a check to indicate it is working. If it
does not come on then, have it xed.
Driver Information Center (DIC)
If the vehicle has a Driver Information Center (DIC),
it is located below the tachometer on the instrument
panel cluster. The DIC gives important safety and
maintenance facts. When the ignition is turned on, the
entire center lights up for just a few seconds.

Your audio system has been designed to operate easily
and to give years of listening pleasure. You will get
the most enjoyment out of it if you acquaint yourself with
it rst. Figure out which radio you have in your vehicle,
nd out what your audio system can do and how to
operate all of its controls to be sure you’re getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off. See
“Retained Accessory Power (RAP)” underIgnition
Positions on page 2-18.
Setting the Time
