Oldsmobile Cutlass Supreme 1993 Owner's Manuals

Weight of the Trailer Tongue
The tongue load (A) of any trailer is
an important weight to measure
because it affects the total capacity
weight of your vehicle. The capacity
weight includes the curb weight of the
vehicle, any cargo you may carry in it,
and the people who
will be riding in
the vehicle. And
if you will tow a
trailer, you must subtract the tongue
load
from your vehicle’s capacity
weight because your vehicle
will be
carrying that -weight, too. See the
Index under Loading Your Vehicle for
more information about your vehicle’s
maximum load capacity. The
trailer tongue
(A) should weigh
10% of the total loaded trailer weight
(B) . After you’ve loaded your trailer,
weigh the trailer and then the tongue,
separately, to see
if the weights are
proper.
If they aren’t, you may be able
to get them right simply by moving
some items around in the trailer.
Total Weight on Your Vehicle’s
Tires
Be sure your vehicle’s tires are inflated
to the limit for cold tires.
You will find
these numbers
on the Certification
label at the rear edge of the driver’s
door or on the inside
of the trunk lid.
See the
Index under Tire L0adin.g.
Then be sure you don’t go over the
GVW limit for your vehicle.
Hitches
It’s important to have the correct hitch
equipment. Crosswinds, large trucks
going by, and rough roads are a few
reasons why you’ll need the right hitch.
Here are some rules to follow:
Will you have to make any holes in
the body of your vehicle when
you
install a trailer hitch? If you do, then
be sure to seal the holes later when
you remove the hitch.
If you don’t
seal them, deadly carbon monoxide
(CO)
from your exhaust can get into
your vehicle. (See the
Index under
Carbon Monoxide in Exhaust. Dirt
and water can, too.

Your Driving and the Road
If You Do Decide to Pull a Trailer
(CONT.)
The bumpers on your vehicle are not
intended for hitches.
Do not attach
rental hitches or other bumper-type
hitches to them. Use only a frame-
mounted hitch that does not attach to
the bumper.
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
If your trailer weighs more than 1,000
pounds (450 kg) loaded, then it needs
its
own brakes-and they must be
adequate.
Be sure to read and follow the
instructions for the trailer brakes
so
you’ll be able to install, adjust and
maintain them properly.
If your vehicle has anti-lock brakes,
do not try to tap into your vehicle’s
brake system. If you do, both brake
systems won’t work well, or at all.
Even if your vehicle doesn’t have anti-
lock brakes, don’t tap into your
vehicle’s brake system if the trailer’s
brake system will use more than
0.02
cubic inch (0.3 cc) of fluid from your

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).
