check engine CADILLAC DEVILLE 1993 7.G User Guide

Downloaded from www.Manualslib.com manuals search engine 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. Pkase
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.
Brake System Warning Light
Your Cadillac’s 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.
This light shoula
come
on and turn off as you
start the vehicle. If it
doesn’t come on then,
have it fixed
so it will
be ready 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 the Index.)

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.

“Drive ahead.” Look down the road, to the sides, and to crossroads
for situations that might affect your passing patterns.
If you have any
doubt whatsoever about making a successful pass, wait for a better
time.
Watch for traffic signs, pavement markings, and lines.
If you can see a
sign up ahead that might indicate a turn or an intersection, delay your
pass. A broken center line usually indicates it’s all right to pass
(providing the road ahead is clear). Never cross a solid line on your
side
of the lane or a double solid line, even if the road seems empty of
approaching traffic.
If you suspect that the driver of the vehicle you want to pass isn’t
aware
of your presence, tap the horn a couple of times before passing.
Do not get too close to the vehicle you want to pass while you’re
awaiting an opportunity.
For one thing, following too closely reduces
your area
of vision, especially if you’re following a larger vehicle. Also,
you won’t have adequate space if the vehicle ahead suddenly slows or
stops. Keep back a reasonable distance.
When it looks like a chance to pass is coming up, start to accelerate
but stay in the right lane and don’t get too close. Time your move
so
you will be increasing speed as the time comes to move into the other
lane.
If the way is clear to pass, you will have a “running start” that
more than makes up for the distance you would lose by dropping back.
And
if something happens to cause you to cancel your pass, you need
only
slow down and drop back again and wait for another opportunity.
If other cars are lined up to pass a slow vehicle, wait your turn. But
take care that someone isn’t trying to pass you as you pull out to pass
the slow vehicle. Remember to glance over your shoulder and check
the blind spot.
Check your mirrors, glance over your shoulder, and start your left lane
change signal before moving out
of the right lane to pass. When you
are far enough ahead
of the passed vehicle to see its front in your
inside mirror, activate
your right lane change signal and move back
into the right lane. (Remember that your right outside mirror
is
convex. The vehicle you just passed may seem to be farther away from
you than it really is.)

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.
