Your Driving and the Road
Driving a Long Distance
Although most long trips today are
made on freeways, there are still many
made on regular highways.
Long-distance driving on freeways and
regular highways is the same
in some
ways. The trip has to be planned and
the vehicle prepared, you drive at
higher-than-city speeds, and there
are
longer turns behind the wheel. You’ll
enjoy your trip more if you and your
vehicle are in good shape. Here are
some tips for a successful long trip.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well
rested. If you must start when you’re
not fresh-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:

driving?
Are the tires all inflated to
the recommended pressure?

weather outlook along your route?

time to avoid a major storm system?

Hill and Mountain Roads
Driving on steep hills or mountains is
different from driving in flat or rolling
terrain.
If you drive regularly in steep
country, or if you’re planning to visit
there, here are some tips that can make
brakes, tires, cooling system and
transaxle. These parts can work hard
on mountain roads.
Know how to go down hills. The most
important thing to laow is this: let
your engine
do some of the slowing
down. Don’t make your brakes do it
all. Shift to a lower gear when you go
down a steep or long hill. That way,
you will slow down without excessive

trips safer and more enjoyable.

when you go downhill.

Know how to go uphill. You may
want to shift down to a lower gear.
The lower gears help cool your engine
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. That way, you won’t be
surprised by a vehicle coming toward

vehicle is passing you and doesn’t
have enough room, slow down to
make it easier for the other vehicle to
get by.

If You’re Caught in a BIiuard
If you are stopped by heavy snow, you
could be in
a serious situation. You
should probably stay with your vehicle
unless you know for sure that you are
near help and you can hike through the
snow. Here
axe some things to do to
summon help and keep yourself and
your passengers safe:
Turn on your hazard flashers.
Tie a red cloth to your vehicle to alert
police that you’ve been stopped by the

Your Driving and the Road
Driving with a Trailer (CONT.)
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 lm/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
D instead of
(or, as you need to, a lower gear).

Using a match near a batteq
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 Freedoms 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
immediately.

have loose or missing insulation.
If
they do, you could get a shock. The
vehicles could be damaged, too.
Before you connect the cables, here are
some things you should
know. Positive

(-) will go to negative (-) or a metal
engine part. Don’t connect
