1993 BUICK RIVIERA check engine light

PASS-Key I1 TM
Your vehicle is equipped with the PASS-Key I1
(Personalized Automotive Security System) theft
deterrent system. PASS-Key
11 TM is a passive theft
deterrent system. This means you don’t have to do
anything different to arm or disarm the system. It works when you insert or remove the key from the ignition.
PASS-Key
TM uses a resistor pellet in the ignition key
that matches a decoder in your vehicle. When
the PASS-Key
I1 TM system senses that someone is
using the wrong key, it shuts down the vehicle’s starter
and fuel systems. For about three minutes, the starter
won’t work and fuel won’t
go to the engine. If someone
tries to start your vehicle again or uses another key during this time, the vehicle will not start. This
discourages someone Erom randomly trying different
keys with different resistor pellets in an attempt to make
a match.
The ignition key must be clean and dry before it’s
inserted in the ignition or the engine may not start. If the
engine doesn’t start and the “SECURITY” light comes
on, the key may be dirty or wet. Turn the ignition
off.
Clean and dry the key. Wait about three minutes and try
again. The security light will remain on during this time. If the starter still won’t work, and the key appears to be
clean and dry, wait about three minutes and try the other
ignition key. At this time, you may also want
to check
the fuse (see “Fuses and Circuit Breakers” in the Index).
If the starter won’t work with the other key, your vehicle
needs service. If your vehicle does start, the first ignition
key may be faulty. See your Buick dealer or
a locksmith
who can service the PASS-Key I1
.
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won’t work and the

When the “LOW OIL LEVEL” light comes on you
should check your engine oil level and
fill if necessary.
See Engine Oil in the Index.

In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index. A computer monitors operation
of your fuel, ignition
and emission control systems. This light should come on when the ignition
is on, but the engine is not running, as
a check to show you it
is working. If it does not come on
at all, have it fixed right away. If it stays
on, or it comes
on while you are driving, the computer is indicating that
you have a problem. You should take your vehicle in for
service soon.

Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts in
Buick dealerships all across North America. They’ll be
ready and willing to help if
you need it.
Here are
some things you can check before a trip:
0 Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
0 Wiper Blades: Are they in good shape!
0 Fuel, Engine Oil, Other Fluids: Have you checked all
levels?
0 Lights: Are they all working? Are the lenses clean?
0 Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving?
Are the tires all inflated to the
recommended pressure? Unless you
are the only driver, it is good to share
the
driving task with others. Limit turns behind the wheel to
about
100 miles (160 km) or two hours at a sitting.
Then, either change drivers or stop for some refreshment
like coffee, tea or soft drinks and some limbering up. But do stop and move around. Eat lightly along the way.
Heavier meals tend to make some people sleepy.
On two-lane highways or undivided multilane highways
that do not have controlled access, you’ll want to watch for some situations not usually found on freeways.
Examples are: stop signs and signals, shopping centers with direct access to the highway, no passing zones and school zones, vehicles turning left and right off the road,
pedestrians, cyclists, parked vehicles. td even animals.
Highway Hypnosis
Is there actually such a condition as “highway
hypnosis”?
Or is it just plain falling asleep at the wheel?
Call
it highway hypnosis, lack of awareness, or
whatever.

There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the
rush of the wind
against the vehicle that can make you sleepy. Don't let it
happen to you! If it does, your vehicle can leave the
road in less than a second. and you could crash and be
injured.
What can you do about highway hypnosis? First, be
aware that
it can happen.
Then here are some tips:
0 Make sure your vehicle is well ventilated, with a
comfortably cool interior.
0 Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors frequently
and your instruments from time to time. This can
help you avoid a fixed stare.'
Wear good sunglasses in bright light. Glare can
cause drowsiness. But don't wear sunglasses at
night. They will drastically reduce your overall vision at the very time you need all the seeing power
you have.
If you get sleepy, pull off the road into a rest, service,
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.
As in any driving situation, keep pace with traffic and
allow adequate following distances.

Driving on steep hills or mountains is different from
driving in flat or rolling terrain.

bags, rags, floor mats -- anything you can wrap around
yourself or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You can’t see
it or
smell it,
so you might not know it was in your
vehicle. Clear away snow from around the ba
!
of your vehicle, especially any that is blocking
your exhaust pipe- And check ar
from time to time to be sure snow
collect there.
Open a window just a little on the side of the
vehicle that’s away from the wind. This
will heir
keep CO out.
I CAUTION: (Continued)
Run your engine only
as long as you must. This saves
fuel. When you run the engine, make
it go a little faster
than just idle. That is, push the accelerator slightly.
This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlights. Let the heater run for awhile.

A CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
flashlight if you need more
light.
Be sure the battery has enough water. You don’t
need to add water to the Delco Freedom@
battery installed
in every new GM vehicle. But if
a battery has filler caps, be sure the right
amount of fluid
is there. If it is low, add water to
take care of that first. If you don’t, explosive gas
could be present.
Battery fluid contains acid that can burn you.
Don’t get
it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immedia

The vehicles could be damaged, too. Before
you connect the cables, here are some things
you should know. Positive (+) will go to positive (+)
and negative (-) will go to negative (-) or
a metal
engine part. Don’t connect
(+) to (-) or you’ll get a
short that would damage the batterv and maybe other
parts, too.
A CAUTION:
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts once the engines are
running.

Damage caused by fluid other than

not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under
“How to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating” in the
Index.
The proper coolant for your Buick
will:
Give freezing protection down to -34’F (-37 ’ C) .
0 Give boiling protection up to 262 ’ F ( 128 ’ C) .
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use:
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets “GM Specification 1825-M,” which won’t damage aluminum
parts. Use GM Engine Coolant Supplement (sealer) with
any complete coolant change. You can also use a
recycled coolant conforming to “GM Specifications
1825-M” with a complete coolant flush and-refill.
If you
use these, you don’t need to add anything else.
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warnin!
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine coul
get
too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you
or others could be burned. Use a
50150 mix of
clean water and
a proper antifreeze.
