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.

Downloaded from www.Manualslib.com manuals search engine 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.
Brake System Warning Light
Your Cadillac hydraulic brake system is divided into two parts. If one part
isn’t working, the other part can still work and stop you. For good
braking, though, you need both parts working
well.
If the warning light goes on, there could be a brake problem. Have your
brake system inspected right away.
BRAKE

This light should come
on as you start the
vehicle. If it doesn’t

on then, have it

to warn you if there’s a
problem.
This light will also come
on when you set your parking brake, and will
stay
on if your parking brake doesn’t release fully. If it stays on after your
parking brake
is fully released, it means you have a brake problem. If the
light comes
on while driving, pull off the road and stop carefully. You may
notice that the pedal is harder
to push. Or, the pedal may go closer to the
floor. It may take longer to stop.
If the light is still on, have the vehicle
towed for service. (See “Towing Your Vehicle” in
