1993 BUICK ROADMASTER ESP

The heavier the rain, the harder it is to see. nven if your
windshield wiper blades are in good shape, a heavy rain
,can make it harder to see road signs and traffid. signals, .
pavement markings, the edge of the road, and even
people walking. Road spray can often be worse for
vision than rain, especially if it
comes frum a dirty road.
So it is wise to keep your wiping equipment in good i.
shape and :keep your windshieklwasher tank filled.
Replace
your windshield' wiper inserts when 'they' show
signs
.of streaking-or missing areas on the windshield, or
when strips
of rubber start to separate from the inserts. Driving,
too fast through large water puddles or even
going through some car washes can cause problems,
too.
The water may affect your brakes. Try to avoid puddles.
But
if you can't, try to slow down before you hit them.

Driving in Fog, Mist and Haze When you drive into a fog patch, your$sibility will be
reduced quickly. The biggest dangers
are striking the
vehicle ahead or being struck by the
one behind. Try to
‘‘read” the fog density down the road.
If the vehicle
ahead starts to become less clear
or, at night; if the
taillights are harder to see,
-the fog is probably
thickening. Slow down to give- traffic behind you. a
chance to slow down. Everybody then has a better chance.to avoid hitting the vehicle ahead.
A patch of derise fog may extend only for a few feet
(meters) or for miles (kilometers); you can’t really tell
while you’re
in it. You can only treat ‘the situation with
extreme tare.
One, common fog condition - sometimes called mist or
ground fog - can happen in weather that seems perfect,
especially at night or in the early
morning in valley and
low, marshy areas. You can be suddenly enveloped
in
thick, wet haze that may even coat ,your windshield. You
can often spot these fog patches .or mist layers with
your
headlights. But sometimes they can be waiting for you
as you come over a hill or dip into a. shallow valley.
Start your windshield wipers and washer, to help clear
accumulated road dirt. Slow down carefully.’
Fog can occur with high humidity or heavy frost. It can
be
so mild that- you can see through it for several
hundred feet (meters). Or-it might
he so thick .that you
can see only
a few feet (meters) ahead. It may come
suddenly
to an otherwise clear road. And it can be a
major hazard.

Driving with a Trailer
Towing a trailer requires a certain amount of experience. Before setting out for the open road, you’ll want to get
to
know your rig. Acquaint yourself with the feel of
handling and braking. with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now
a good deal longer and not nearly so
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform,
safety chains, electrical connector, lights, tires and
mirror adjustment.
If the trailer has electric biakes, start
your yehicle and trailer moving and then apply the
trailer brake controller by hand to be sure the- brakes are
working. This lets you check your electrical connection
at the same time.
During your trip, check occasionally to
be sure that the
load
is secure, and that the Lights.and any trailer brakes
are .still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help
you avoid situations that require heavy braking
and sudden turris.
.
Passing
You’ll need. more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal \
longer, you’ll need to go much farther beyond the
.
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer
to the left, just move that hand
to the left.
To mo.ve the trailer to the right, move your
hand to the right. Always back up slowly and, if
possible, have someone guide
you.
Making Turns
When you’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or other objects.
Avoid jerky or sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have .a
different turn signal flasher and extra wiring. The green
arrows on your instrument panel will
flash whenever
you signal a
turn or lane change. Properly hooked up,

What about gasoline with blending materials that contain oxygen, such as MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is, no
more than 15% MTBE is fine for your vehicle.
Ethanol is ethyl or .grain alcohol. Properly-blended fuel
that
is no more than 10% ethanol is fine for your
vehicle.
Methanol is methyl or
wood alcohol. Gasolines
for Cleaner Air
Your use
of gasoline with detergent additives will help
prevent deposits from forming in your engine:and
fuel
system. That helps keep your ,engine in. tune and your
emission control system working properly. It’s good
for
your vehicle, and you’ll be doing your part for cleaner
air.
Many gasolines are now blended with materials called
oxygenates. General Motors .recommends that you use
gasolines with these blending materials, such as MTBE
and-ethanol. By doing so, you can help clean the
ak,
especially in those parts of the country that have high
carbon monoxide levels.
In addition, som-e gasoline suppliers are now .producing
reforniulated gasolines. These gasolines are specially
designed to reduce vehicle emissions. General Motors
recommends that you use reformulated gasoline. By
doing
so, you can help clean the air, especially in those
parts
of the country that have high ozone levels.
You should ask your service station operators if their
gasolines contain detergents and oxygenates, and
if they
have been reformulated to reduce vehicle emissions.

How to Add Fluid:
Refer to the Maintenance Schedule to determine what
kind
of transmission fluid to use. See “Recommended
Fluids and.lLubricants” in the Index.
If the fluid level is low, add only enough of the proper
fluid to bring the level up to the COLD area for a cold
check or the
HOT area fora hot check. It doesn’t take
much fluid, generally less than a pint. Don’t overfill.
we
recommend you use only fluid labeled DEXRONBIIE,
because fluids with that label are made-especially for
you automatic transmission. Damage caused by fluid
other than DEXRON@IIE
is not covered by your new
vehicle warranty.
0 After adding fluid, recheck the fluid level as
described under “How to Check.77
0 When the correct-fluid level is obtained, push the
dipstick back in all the way.
Rear Axle
When to Check and Change Lubricant:
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Periodic Maintenance Inspections” in the Index.
How to Check Lubricant:
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom
of the filler plug hole.
What
to Use:
Standard Differential
Use Axle Lubricant (GM Part
No. 1052271) or SAE
80W-90 GL-5 gear lubricant.
Limited-Slip Differential
To add lubricant when the level is low, use Axle
Lubricant (GM Part
No. 1052271) or SAE 8OW-90
GL-5 gear lubricant.
To completely refill after draining,
add
4 ounces (1 18 ml) of Limited-Slip Differential
Lubricant Additive (GM Part
No. 1052358). Then fill to
the bottom of the filler plug hole with Axle Lubricant
(GM Part
No. 1052271) or SAE 80W-90 GL-5 gear
lubricant.

When to Check: Check your tires once .a month or
more.
Don’t forget
your compact spare-tire (if SO equipped). It
should be at 60 psi (420 Pa).
How to Check: Use a good quality pocket-type gage to
check tire pressure. Simply looking at the tires will not
tell you the pressure, especially if
you have radial tires
- which may look properly inflated even if they’re
underinflated.
If your tires have valve caps, be sure to put them back
.on. They help prevent leaks by keeping
out dirt and
moisture.
Tire Inspection and Rotation
To make your tires last longer, have them inspected and
rotated at the mileages recommended in the, Maintenance Schedule. See “Scheduled Maintenance Services”
in the Index.
Use this rotation pattern.
