Torque Lock
If you are parking on a hill and you don’t shift your
transmission into PARK
(P) properly, the weight of the
vehicle may put too much force
on the parking pawl in
the transmission. You may find it difficult to pull the
shift lever out of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and then
shift into PARK
(P) properly before you leave the
driver’s seat.
To find out how, see “Shifting Into
PARK (P)” in the Index.
When you are ready
to drive, move the shift lever out of
PARK (P) h If torque lock does occur, yo^^ may need to have another
vehicle push yo~~rs
a little uphill to take some of the
pressure from
the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
Your vehicle has a brake-transmission shift interlock.
You have to fully apply your regular brake before you
can shift from PARK
(P) when the ignition is in the
RUN position. See “Automatic Transmission Operation”
in the Index.
If you cannot shift out of PARK (P), ease pressure on
the shift lever -- push the shift lever all the way into
PARK
(P) as you maintain brake application. Then press
the shift lever button and move the shift lever into the
gear you want.
If you ever hold the brake pedal down but still can’t
shift
out of PARK (P), try this:
1. Turn the key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL(N).
4. Start the vehicle and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.

Drunken Driving
Death and injury associated with drinking and driving is
a national tragedy. It’s the number one contributor to the
highway death toll, claiming thousands
of victims
every year.
Alcohol affects
four things that anyone needs to drive
a vehicle:
Judgment
0 Muscular Coordination
Vision
0 Attentiveness.
Police records show that almost half
of all motor
vehicle-related deaths involve alcohol.
In most cases,
these deaths are the result of someone who was drinking
and driving.
In recent years, some 17,000 annual motor
vehicle-related deaths have been associated
with the use
of alcohol, with more than 300,000 people injured.
Many adults
-- by some estimates, nearly half the adult
population
-- choose never to drink alcohol, so they
never drive after drinking. For persons under
2 I , it’s
against the law in every U.S. state to drink alcohol.
There are good medical, psychological and
developmental reasons for these laws. The
obvious way to solve this highway safety problem
is for people never to drink alcohol and then drive. But
what if people do? How much is “too much” if the
driver plans
to drive? It’s a lot less than many might
think. Although
it depends on each person and situation,
here is some general information
on the problem.
The Blood Alcohol Concentration (BAC) of someone
who is drinking depends upon four things:
The amount of alcohol consumed
e The drinker‘s body weight
0 The amount of food that is consumed before and
during drinking
The length of time it has taken the drinker to
consume the alcohol.
According to the American Medical Association,
a
180-lb. (82 kg) person who drinks three 12-ounce
(355 ml) bottles of beer in an hour will end up with a
BAC of about 0.06 percent. The person would reach the
same BAC
by drinking three 4-ounce ( 120 ml) glasses
of wine or three mixed drinks
if‘ each had 1 - 1/2 ounces
(45 ml) of a liquor like whiskey, gin or vodka.
ProCarManuals.com

It’s the amount of alcohol that counts. For example, if
the same person drank three double martinis (3 ounces
or
90 ml of liquor each) within an hour, the person’s
BAC would be close to 0.12 percent. A person who
consumes food just before or during drinking will have a
somewhat lower BAC level. There
is a gender difference, too. Women
generally have
a lower relative percentage of body water than men.
Since
alcohol is carried in body water, this means that a
woman generally will reach a higher BAC level than a
man of her same body weight when each has the same
number
of drinks.
The law
in many U.S. states sets the legal limit at a BAC
of 0.10 percent. In a growing number of U.S. states, and
throughout Canada, the
limit is 0.08 percent. In some
other countries, it’s even lower. The BAC limit for all
commercial drivers
in the United States is 0.04 percent.
The BAC will be over
0.10 percent after three to
six drinks (:in one hour). Of course, as we’ve seen, it
depends on how much alcohol is
in the drinks, and how
quickly the person drinks them.

Control of a Vehicle
You have three systems that make your vehicle go where
you want it to
go. They are the brakes, the steering and
the accelerator. All three systems have to do their work
at the places where the tires meet the road.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That’s perception time. Then you have to bring up your
foot and do it. That’s reaction time.
Average reaction time is about 3/4 of a second. But
that’s only an average. It might be less with one driver
and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination
and eyesight all play a part.
So do alcohol, drugs and
frustration. But even in 3/4 of a second, a vehicle
moving at
60 mph (100 km/h) travels 66 feet (20 m).
That could be a lot of distance in an emergency, so
keeping enough space between your vehicle and others
is important.
And, of course, actual stopping distances vary greatly
with the surface of the road (whether it’s pavement or
gravel); the condition of the road (wet, dry, icy); tire
tread; the condition
of your brakes; the weight of the
vehicle and the amount of brake force applied.
~ Sometimes, as when you’re driving on snow or ice, it’s
1 easy to ask more of those control systems than the tires
and road can provide. That means you can lose control
of your vehicle.

Driving Across an Incline
Sooner or later, an off-road trail will probably go across
the incline
of a hill. If this happens, you have to decide
whether to try to drive across the incline. Here are some
things to consider:
A hill that can be driven straight up or down may be
too steep to drive across. When you go straight up or
down
a hill, the length of the wheel base (the
distance from
the front wheels to the rear wheels)
reduces the likelihood the vehicle will tumble end
over end.
But when you drive across an incline, the
much more narrow track width (the distance between
the left and right wheels) may not prevent the vehicle
from tilting and rolling over. Also, driving across an
incline puts more weight on the downhill wheels.
This could cause
a downhill slide or a rollover.
Surface conditions can be a problem when you drive
across
a hill. Loose gravel, muddy spots, or even wet
grass can cause your tires to
slip sideways, downhill.
If the vehicle slips sideways, it can hit something
that will trip it
(a rock, a rut, etc.) and roll over.
Hidden obstacles can make the steepness of the
incline even worse. If you drive across a rock with
the uphill wheels, or if the downhill wheels drop into
a rut or depression, your vehicle can
tilt even more.
For reasons like these, you need to decide carefully
whether to
try to drive across an incline. Just because
the trail goes across the incline doesn’t mean you
have
to drive it. The last vehicle to try it might have
1-01 led over.
Driving across an incline that’s too steep will
make your vehicle roll over. You could be
seriously injured or killed.
If you have any doubt
about the steepness
of the incline, don’t drive
across it. Find another route instead.

Loading Your Vehicle
The Certification/Tire label is found on the driver’s door
edge, above the door latch. The label shows the size of
your original tires and the inflation pressures needed to
obtain the gross weight capacity
of your vehicle. This is
called the
Gross Vehicle Weight Rating (GVWR). The
GVWR includes the weight
of the vehicle, all occupants,
fuel, cargo and trailer tongue weight,
if pulling a trailer.
The Certification/Tire label also tells you the maximum
weights
for the front and rear axles, called Gross Axle
Weight Rating (GAWR).
To find out the actual loads on your
front and rear axles, you need to
go to a weigh
station and weigh your vehicle.
Your retailer can help
you
with this. Be sure to spread out your load equally on
both sides
of the centerline.
Never exceed the GVWR for your vehicle,
or the
GAWR for either the front
or rear axle.
If you do have a heavy load, you should spread it out.
Similar appearing vehicles may have different GVWR’s
and payloads. Please note
your vehicle’s
Certificationflire label or consult your retailer
for
additional details.
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can
break, or it can change the
way your vehicle
handles. These could cause you to lose control.
Also, overloading can shorten the life of
your vehicle.

Using heavier suspension components to get added
durability might not change your weight ratings.
Ask
your retailer to help you load your vehicle the right way.
I NOTICE:
Your warranty does not cover parts or
components that fail because of overloading.
If you put things inside your vehicle -- like suitcases,
tools, packages or anything else
-- they will go as fast as
the vehicle goes.
If you have to stop or turn quickly, or
if there is a crash, they’ll keep going.
There’s
also important loading information for off-road
driving in this manual. See “Loading Your Vehicle’’ in
the Index.
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn,
or in a crash.

Put things in the cargo area of your vehicle.
Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle
so that some of them are
above the tops of the seats.
Don’t leave an unsecured child restraint in
your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Don’t leave a seat folded down unless you

Payload
The payload capacity is shown on the Certificationrnire
label. This is the maximum load capacity that your
j vehicle can carry. Be sure to include the weight of the
1 occupants as part of your load. If you added any
accessories or equipment after your vehicle left the
factory, remember to subtract the weight of these things
from the payload. Your retailer can help you with this.
Add-on Equipment
When you carry removable items, you may need to put a
limit
on how many people you carry inside your vehicle.
Be sure to weigh your vehicle before you buy and install
the new equipment.

Towing a Trailer
If you don't use the correct equipment and drive
properly, you can lose control when you pull
a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
Pull
a trailer only if you have followed all the
steps in this section.
Ask your Oldsmobile retailer
for advice and information about towing
a trailer
with your vehicle.

Three importmt considerations have to do with weight:
the weight of the trailer,
the weight of the trailer tongue
* and the weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
5,000 lbs. (2 270 kg).
But
even that can be too heavy.
It depends
on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull
a
trailer are all important. And, it can also depend on any
special equipment that
you have on your vehicle.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight
to measure because it affects the total or gross
weight of your vehicle. The Gross Vehicle Weight
(GVW) 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 add the tongue load to the GVW because your
vehicle will be carrying that weight, too. See “Loading
Your Vehicle”
in the Index for more information about
your vehicle’s maximum load capacity.
4-46
ProCarManuals.com

A B
If you’re using a weight-carrying hitch, the trailer
tongue
(A) should weigh 10 percent of the total loaded
trailer weight
(B). If you’re using a weight-distributing
hitch, the trailer tongue
(A) should weigh 12 percent 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 upper
limit
for cold tires. You’ll find these numbers on the
Certification/Tire label
on the driver’s door edge, above
the door latch or see “Tire Loading”
in the Index. Then
be sure
you don’t go over the GVW limit for your
vehicle, including the weight
of the trailer tongue.
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:
If you’ll be pulling a trailer that, when loaded, will
weigh more than 2,000 Ibs. (900 kg), be sure to use a
properly mounted, weight-distributing hitch and
sway control of the proper size. This equipment is
very important for proper vehicle loading and good
handling when you’re driving.
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 relnove the hitch.
If you don’t seal them, deadly
carbon monoxide (CO) from your exhaust can get
into your vehicle (see “Carbon Monoxide”
in the
Index). Dirt and water can, too.
