The control is next to the headlight switch. It switches your lights on and
off by sensing how dark it is outside. To operate it, leave the light switch
off and move the control to any position but off.
If you move the control all the way to MAX, your lights will remain on for
90 seconds after you turn your engine off. If you move the control almost
all the way in the other direction,
so it is just on, the lights will go off
quickly when you turn off your engine. You can change this delay time
from
only a few seconds to 90 seconds.
Operation of Lights
Although your vehicle’s lighting system (headlamps, parking lamps, fog
lamps, side marker lamps and tail lamps) meet all applicable Federal
lighting requirements, certain States and Provinces may apply their own
lighting regulations that may require special attention before you operate
these lamps. For example, some jurisdictions may require that you
operate your lower beam lamps with fog lamps at all times, or that
headlamps be turned on whenever you must use your windshield wipers.
In addition, most jurisdictions prohibit driving solely with parking lamps,
especially at dawn or dusk.
It is recommended that you check with your
own State or Provincial highway authority for applicable lighting
regulations.

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.
