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.
Hydroplaning
Hydroplaning is dangerous. So much
water can build up under your tires that
they can actually ride
on the water. This
can happen if the road is wet enough
and you’re going fast enough. When
your vehicle is hydroplaning, it has little
or no contact with the road.
Hydroplaning doesn’t happen often.
But it can
if your tires haven’t much
tread or
if the pressure in one or more is
low. It can happen if a lot of water is
standing on the road. If you can see
reflections from trees, telephone poles,
or other vehicles, and raindrops
“dimple” the water’s surface, there
could be hydroplaning.
Hydroplaning usually happens at higher
speeds. There
just isn’t a hard and fast
rule about hydroplaning; The best
advice is to slow down when it is
raining.
Some .Other Rainy Weather Tips
Turn on your low-beam headlights -
not just your parlcing lights - to help
make you more visible to others.
Besides slowing down, allow some
extra following distance. And be
especially careful when you pass
another vehicle. Allow yourself more
clear room ahead, and be prepared to
have your view restricted by road
spray.
Have good tires with proper tread
depth. (See
Tires in the Index.)

City Driving
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:
IOnow the best way to get to where
you are going. 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
cris.scross 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.

4 Freeway Driving
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 dtiving.
roo-fast
or too-slow dri,ving breaks a
smooth traffic flow. Treat the left lane
on akeeway as a passing lane. -
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

Reduce your speed according to your
speedometer, not to your sense
of
motion. After driving for any distance at
higher speeds, you may tend to think
you are going slower than you actually
are.
4 Before Leaving on a Long
Trip
Make sure you’re ready. Try to be well
rested.
If you must start when you’re
not
fr&- such as after a day’s work
- don’t plan to make too many miles
that first part of the journey. Wear
comfortable clothing and shoes
you can
easily drive in.
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 Oldsmobile 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:

and transaxle, and you can climb the
hill better.
Stay in your own lane when driving
on two-lane roads in hills or
mountains. Don't swing wide or cut
across the center
of the road. Drive at
speeds that let you stay in your
own
lane.
As you go over the top of a hill, be
alert. There could be something in
your lane, like a stalled car or an
accident.
You may see highway signs on
mountains that warn of special
problems. Examples are long grades,
passing
or no-passing zones, a falling
rocks area, or winding roads. Be alert
to these and take appropriate action.
I Winter Driving
Here are some tips for winter driving:
Have your Oldsmobile in good shape
for winter. Be sure your engine
coolant mix- is correct.
You may want to put winter
emergency supplies in your trunk.
Include an ice scraper, a small brush or
broom, a supply
of windshield washer
fluid, a rag, some winter outer clothing,
a small shovel, a flashlight, a red cloth,
and a couple
of reflective warning
triangles. And,
if you will be driving
under severe conditions, include a
small
bag of sand, a piece of old carpet or a
couple
of burlap bags to help provide
traction. Be sure
you properly secure
these items in your vehicle.

Safety Chains
You should always attach chains
between your vehicle and your trailer.
Cross the safety chains under the
tongue of the trailer
so that the tongue
will not drop to the road if it becomes
separated from the hitch. Instructions
about safety chains may be provided by
the hitch manufacturer or by the trailer
manufacturer. Follow the
manufacturer’s recommendation for
attaching safety chains. Always leave
just enough slack
so you can turn with
your rig. And, never allow safety chains
to drag
on the ground.
Trailer Brakes
Because you have anti-lock brakes,
don’t try to tap into your vehicle’s brake
system at all.
If you do, both brake
systems won’t work well or
at all.
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 laow 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
brakes, start your vehicle 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
turns.
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 move 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, the trailer
lights will also flash, telling other
drivers you’re about to turn, change
lanes or stop.
When towing
a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think
drivers behind you are seeing your
signal when they are not. It’s important
to check occasionally to be sure the
trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade.
If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
work well. On
a long uphill grade, shift down and
reduce your speed to around
45 mph
(70 ltm/h) to reduce the possibility of
engine and transaxle overheating.
If you are towing a trailer and you have
an automatic transaxle with Overdrive,
you may want to drive in
3 instead of D
(or, as you need to, a lower gear).
Parking on Hills
You really should not park your vehicle,
with a trailer attached, on a hill.
If
something goes wrong, your rig could
start to move. People can be injured,
and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on
a hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
P (Park) yet.
2. Have someone place choclts under
the trailer wheels.
3. When the wheel choclts are in place,
release the regular brakes until the
choclts absorb the load.
4. Reapply the regular brakes. Then
apply your parking brake, and then
shift to
P (Park).
5. Release the regular brakes.
When You Are Ready to Leave
After Parking on a Hill
1. Apply your regular brakes and hold
the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
of the chocks.
4. Stop and have someone pick up and
store the chocks.

Service & Appearance Care
Engine Oil
If the LOW OIL LEVEL light on the
instrument panel comes
on, it means
you need to check your engine oil level
right away. For more information, see
Low Oil Level Light in the Index. You
should check your engine oil level
regularly; this is an added reminder.
It’s a good idea to check your engine .oil
:
every time you get fuel. In order to get
an accurate reading, the oil must be
warm and the vehicle must be on level
ground.
Turn
off the engine and give the 0il.a
few minutes to drain back into the
oil
pan. If you don’t, the oil dipstick might
not show the actual level.
To Check Engine Oil
Pull out the dipstick and clean it with-a
paper towel or cloth, then push it bzck
in all the way. Remove it again, keeping
the tip lower, and check the level.

When to Add Oil
If the oil is at or below the ADD line,
then you’ll need to add some
oil. But
you must use the right kind. This
section explains what kind
of oil to use.
For crankcase capacity, see
Capacities
and Specifications
in the Index.
NOTICE:
Don’t add too much oil. If your
engine has
so much oil that the oil
level gets above the cross-hatched
area that shows the proper
operating range, your engine could
be damaged.
Just fill it enough to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when you’re through.
