You may wonder what happens if a car has to have a new odometer
installed. The new one may read the correct mileage. This
is because your
car’s computer
has stored the mileage in memory. If it isn’t stored, then
this odometer
is set at zero, but a label on the driver’s door must show the
old reading and when the new one was installed.
WARNING LIGHTS
This section describes the warning lights that may De on your vehicle. The
pictures will help you locate them.
Warning lights can signal that something is wrong before
it becomes
serious enough
to cause an expensive repair or replacement. Paying
attention to your warning lights could also save you
or others from injury.
Warning lights go 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 turn the ignition key just to
let you
know they’re working. If you are familiar with this section, you
should not be alarmed when this happens.
When one
of the warning lights comes on and stays on when you are
driving, check the section that tells you what to do about it. Please follow
the manual’s advice. Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights. They’re a big help.
Your vehicle may also have a driver information system that works along
with.
. the ,. warning lights. See “Driver Information System” in the Index.

“95 OIL LIFE INDEX,” for example, that means that the way you’re
driving your car,
95% of your current oil life is still left.
The
“OIL LIFE INDEX’ may say to change the oil sooner than your
maintenance schedule. This can happen
if driving conditions, such as
short trips in cold weather, cause shorter oil life. Always keep a written
record
of the mileage and date when you last changed your oil. For more
information on
when to change your oil, see the “Maintenance
Schedule.”
If you see “CHANGE OIL
SOON,” it means that you have less than 10%
of your oil life left, and you should consider changing your engine oi\
l.
If you see
“CHANGE ENGINE OIL,” it means the oil life is gone and
you should change the oil right away (certainly within
200 more miles
[320 km]).
The system probably will say to change the oil between 3000 miles (5000
km) and 7500 miles (12500 km), but it may even say to change it before
3000 under very severe conditions. It all depends on your driving
patterns. If it’s been
7500 miles (12500 km) it will say to change oil.
There are
two things the system doesn’t do:
It can’t sense heavy dust in the places where you drive. If you drive in
a dusty area, you should change your oil every 3000 miles (5000 km)
or
3 months (whichever comes first), unless the display says to change
it even sooner than that.
It doesn’t check how much oil you have, so you’ll still have to check
Also, for the system to work right, it is important that you use SG oil, as
discussed earlier. for that.
To see how,
see Index under “Engine Oil.”
when You’ve Changed the Oil
When new oil is put in, you’ll need to reset your system. To do it, display
the “OIL LIFE INDEX’ by pressing the “Information” button. Then
press and hold the “STORE/RECALC’ buttons
until the display shows
“100.”
