Charge Light
When you turn the key
to “Run,” this light will
come on briefly, to
show that your
alternator and battery
charging systems are
working.
If a light stays on, you need service, and you should take your Cadillac to
the dealer at once.
To save your battery until you get there, turn off all
accessories, and set your Electronic Climate Control system to “OFF.”

Oil Light
This light tells you if
there could be a
problem with your
engine
oil pressure.
The light goes on when you turn your key to “Run” or
“START” It goes
off once you have started your engine. That’s just a check to be sure the
light works. If it doesn’t, be sure
to have it fixed so it will be there to warn
you if something goes wrong.
When this light comes on and stavs on, it means
oil isn’t going through
your engine properly. You could be
low on oil, or you might have some
other oil problem.

A CAUTION:
Don’t keep driving if the oil pressure is low. If you do, your
engine can become
so hot that it catches fire. You or others
could be burned. Check your oil
as soon as possible and have
your vehicle serviced.

The light will also come on following engine start up for
20 seconds when
either the oil life percentage
is less the 10% or 7500 miles (12500 km)
have been driven. This is a reminder that it is time to change your oil. See -
the Index under “Oil Life Indicator” for more information on this system.

cl
Press and hold the
Range and Fuel Used
buttons to display the
oil life percentage.
You’ll
see how much oil life you have left, as a percentage. So if you see
“94” for example, that means that the way you’re driving your vehicle,
94%
of your current oil life is still left.
The
“CHANGE OIL SOON” light will come on for a few seconds as a
bulb check when you start your engine. The light will also come on for
20
seconds following engine start-up when either the oil life percentage is
less the
10% or 7,500 miles (12500 km) have been driven. 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 miles
under severe conditions. It all depends on your driving patterns.
(If it
doesn’t,
or if it doesn’t even light up, then something is wrong. You will
need to have it serviced.)
There
are two things the system won’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 “CHANGE
OIL SOON” light comes on sooner.
It doesn’t check how much oil you have
so you will still have to check for
that.
To check it, see the 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 that, press
and hold the “Range” and “Reset” buttons between
5 and 60 seconds.

Downloaded from www.Manualslib.com manuals search engine - High Beams
If the vehicle approaching you has its high beams on, signal by flicking
yours to high and then back to low beam. This is the usual signal to
lower
the headlight beams. If the other driver still doesn’t lower the beams,
resist the temptation to put your high beams on. This only makes
two
half-blinded drivers.
7
On a freeway, use your high beams only in remote areas where you won’t
impair approaching drivers. In some places, like cities, using high beams
is illegal.
When you follow another vehicle on
a freeway or highway, use low
beams. True, most vehicles now have day-night mirrors that enable the
__ driver to reduce glare. But outside mirrors are not of this type and high
beams from behind can bother the driver ahead.
A Few More Night Driving Suggestions
Keep your windshield and all the glass on your vehicle clean -- inside and
out. Glare at night is made much worse by dirt on the glass. Even the
inside
of the glass can build up a film caused by dust. Tobacco smoke also
makes inside glass surfaces very filmy and can be a vision hazard if it’s left
there.
Dirty glass makes lights dazzle and flash more than clean glass would,
making the pupils
of your eyes contract repeatedly. You might even want
to keep a cloth and some glass cleaner
in your vehicle if you need to clean
- your glass frequently.
Remember that your headlights light up far less
of a roadway when you
are in a turn or curve.
Keep your eyes moving; that way, it’s easier to pick out dimly lighted
objects.
Just as your headlights should be checked regularly for proper aim,
so
should your eyes be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and aren’t even aware of it.

One of the biggest problems with city streets is the amount of traffic on
them. You’ll want to watch out for what the other drivers are doing and
pay attention to traffic signals.
Here are ways to increase your safety in city driving:

0
Know the best way to get to where you are going. Try not to drive
around trying to pick out a familiar street or landmark. Get
a city map
and plan your trip into an unknown part
of the city just as you would
for a cross-country trip.
Try to use the freeways that rim and crisscross most large cities. You’ll
save time and energy.
(See the next section, “Freeway Driving.”)
Treat a green light as a warning signal.
A traffic light is there because
the corner is busy enough to need it. When a light turns green, and
just before you start
to move, check both ways for vehicles that have
not cleared the intersection
or may be running the red light.

Downloaded from www.Manualslib.com manuals search engine Obey all posted speed limits. But remember that they are for ideal
road, weather and visibility conditions. You may need to drive below
the posted limit in bad weather or when visibility is especially poor.
Pull to the right (with care) and stop clear of intersections when you
see or hear emergency vehicles.
FREEWAYDWNG
Mile for mile, freeways (also called thruways, parkways, expressways,
turnpikes, or superhighways) are the safest
of all roads. But they have
their own special rules.
The most important advice on freeway driving is: Keep up with traffic and
keep to the right. Drive
at the same speed most of the other drivers are
driving. Too-fast
or too-slow driving breaks a smooth traffic flow. Treat
the left lane
on a freeway as a passing lane.
Entering the Freeway
At the entrance there is usually a ramp that leads to the freeway. If you
have a clear view
of the freeway as you drive along the entrance ramp,
you should begin to check traffic. Try to determine where you expect to
blend with the
flow. If traffic is light, you may have no problem. But if it is
heavy, find a gap as you move along the entering lane and time your
approach.
Try to merge into the gap at close to the prevailing speed.
