Climate Control
The air conditioner and heater work
best
if you keep your windows closed
while using them. Your vehicle also has
the flow-through ventilation system
described later in this section.
OFF: Press to turn the blower off.
Some air will still come from the outlets
at the floor. Press any function button
to turn the system
on.
Temperature Control Lever: This
lever changes the temperature of the air
coming through the system. The higher
the lever setting, the warmer the air.
3f: Selects the force of air you want.
Press
LO to lower the fan speed, HI to
raise
it.
Air Conditioning
On very hot days, open the windows
long enough to let hot inside air escape.
This reduces the time it tales for your
vehicle to cool down, which should help
fuel economy.
There are three air conditioning
settings:
MAX: Provides maximum cooling or
quick cool-down
on very hot days. This
setting also helps prevent outside odors
from entering your vehicle.
This setting recirculates much of the air
inside your vehicle, and it should not be
used for long periods because the air
may become too cold and
dry. This
setting is not recommended if an
occupant is smoking.
NORM: Use for normal cooling on hot
days. This setting brings in outside air,
cools it and directs it through the
instrument panel outlets.
BI-LEV (Bi-Level): Use on cool, but
sunny days. This setting brings in the
outside air, but directs it in two ways.
The cool air is directed to the upper
portion of your body through the
instrument panel outlets, but most
warmed air is directed through the
heater ducts and a little to the defrost
and side window vents. At times this
temperature difference may be more
apparent than others.

Do not tow a trailer if you have a
convertible with the 3.4L VIN Code X
engine.
Your Oldsmobile can tow a trailer. To
identify what the vehicle trailering
capacity is for your vehicle, you should
read the information in
Weight of the
Trailer that appears later in this section.
But trailering is different than just
driving your vehicle by itself. Trailering
means changes in handling, durability,
and fuel economy. Successful, safe
trailering takes correct equipment, and
it has to be used properly.
That’s the reason for this section. In it
are many time-tested, important
trailering tips and safety rules. Many of
these are important for your safety and that
of your passengers.
So please read
this section carefully before you pull a
trailer.
Load-pulling components such as the
engine, transaxle, wheel assemblies, and
tires are forced to work harder against
the drag of the added weight. The
engine
is required to operate at
relatively higher speeds and under
greater loads, generating extra heat.
What’s more, the trailer adds
considerably to wind resistance,
increasing the pulling requirements.
All of that means changes in:
Handling
Durability
Fuel economy
If You Do Decide to Pull a Trailer
If you do, here are some important
points.
There are many different laws having
to do with trailering. Make sure your
rig
will be legal, not oplly where you
live but also where you’ll be driving.
A
good source for this information can
be state or provincial police.
Consider using a sway control. You
can ask a hitch dealer about sway
controls.
Don’t tow a trailer at all during the
first
500 miles (800 km) your new
vehicle is driven. Your engine, axle or other parts could be damaged.
177

If it’s bad enough, it can damage your
engine.
If you’re using fuel rated at 87 octane or
higher and you still hear heavy
laoclcing, your engine needs service.
But don’t
worry if you hear a little
pinging noise when you’re accelerating
or driving up a hill. That’s normal, and
you don’t have to buy
a higher octane
fuel to get rid
of pinging. It’s the heavy,
constant knock that means you have a
problem.
Fuel Capacity:
16.5 U.S. Gallons (62 L). Use unleaded
fuel only.
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.

Replacement blades come in different
types and are removed
in different
ways. Here’s how to remove the type

Loading Your Vehicle
Two labels on your vehicle show how
much weight it may properly carry. The
Tire-Loading Information label found on the inside
of the trunlc lid tells you
the proper size, speed rating and
recommended inflation pressures for
the tires on your vehicle. It
also gives
you important information about the
number
of people that can be in your
vehicle and the total weight that you
can carry. This weight is called the
Vehicle Capacity Weight and includes
the weight
of all occupants, cargo, and
all nonfactory-installed options.
The other label is the Certification label,
on the rear edge
of the driver’s door. It
tells you the gross weight capacity
of
your vehicle, ded the GVWR (Gross
Vehicle Weight Rating). The GVWR
includes the weight of the vehicle,
all
occupants, fuel and cargo. Never exceed
the
GVWR for your vehicle, or the
Gross Axle~Weight Rating (GAWR) for
either the front
or rear axle.
And,
if you do have a heavy load, you
should spread it out. Don’t cany
more
than 167 lbs, (75 kg) in your trunk.
