To maintain a comfortable temperature in the rear, use
either rear fan control to adjust the force of air coming
through the rear outlets.
Select the desired climate control mode using the
directional controls on the instrument panel (see ªMode
Knobº earlier in the section). The mode you choose will
regulate both the front and rear climate control systems.
Rear Air Vents
To maximize airflow through the rear heater outlet,
place the left bucket seat in the second row in the
forward position (see ªAdjusting Rear Seatsº in
the Index).
The vent behind the left rear seat is the cold air return
vent. Be sure to keep it free of obstructions.
Keep the area around the base of the center instrument
panel console and between and under the front seats free
of objects that could obstruct airflow to the rear.

3-8 Ventilation System
Your vehicle's flow-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the fan is running.
Your vehicle has air outlets that allow you to adjust the
direction and amount of airflow inside the vehicle. Push
the outlet up or down to direct airflow to your
preference. Increase or reduce the amount of airflow by
opening and closing the louvers. Opening and closing
the louvers will also direct airflow from side to side.
The air
-flow through the vents can be shut off
completely by turning the thumb
-wheel next to each
outlet all the way down. You can also stop outside air
from entering by turning the fan to OFF and pushing the
RECIRCULATION button.
Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). This will
allow the heater and defroster to work much better,
reducing the chance of fogging the inside of
your windows.

When you enter a vehicle in cold weather, turn the
blower fan to its highest setting ª5º for a few
moments before driving off. This helps clear the
intake ducts of snow and moisture, and reduces the
chance of fogging the inside of your windows.

Keep the area around the base of the center
instrument panel console and the air path under the
front seats clear of objects. This helps air to circulate
throughout your vehicle.

In cold weather, operating the system in the
OUTSIDE AIR mode will improve the time it takes
to warm the vehicle.

4-38 Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
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
extra wiring.
The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you're about to turn, change lanes or stop.When towing a trailer, the 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.
If you are towing a trailer that weighs more than
1,000 lbs. (450 kg), you may prefer to drive in
THIRD (3) instead of AUTOMATIC OVERDRIVE (D)
(or, as you need to, a lower gear). This will minimize
heat build
-up and extend the life of your transaxle.

Towing Your Vehicle
CAUTION:
To help avoid serious personal injury to you
or others:

Never let passengers ride in a vehicle that is
being towed.

Never tow faster than safe or posted speeds.

Never tow with damaged parts not
fully secured.

Never get under your vehicle after it has
been lifted by the tow truck.

Always secure the vehicle on each side with
separate safety chains when towing it.

Use only the correct hooks.
NOTICE:
Use the proper towing equipment to avoid
damage to the bumper, fascia or fog lamp areas
of the vehicle.
With current trends in automotive styles and design, it is
essential that the correct towing equipment is used to
tow a vehicle. Your vehicle can be towed with wheel
-lift
or car
-carrier equipment. Don't have your vehicle towed
on the drive wheels, unless you must. If the vehicle must
be towed on the drive wheels, do not tow the vehicle
more than 500 cumulative miles (800 km) or exceed
50 mph (80 km/h). If these limitations must be
exceeded, then the drive wheels have to be supported on
a dolly.
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº in the Index.
Engine Overheating
You will find a coolant temperature gage on your
vehicle's instrument panel. See ªEngine Coolant
Temperature Gageº in the Index. You also have a low
coolant level light on your instrument panel. See ªLow
Coolant Lightº in the Index.

If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate on fuels that meet
California specifications. If such fuels are not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator
lamp on your instrument panel may turn on and/or your
vehicle may fail a smog
-check test. (See ªMalfunction
Indicator Lampº in the Index.) If this occurs, return to
your authorized Oldsmobile dealer for diagnosis to
determine the cause of failure. In the event it is
determined that the cause of the condition is the type of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane
-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask your service station operator whether or not
the fuel contains MMT. General Motors does not
recommend the use of such gasolines. If fuels containing
MMT are used, spark plug life may be reduced and your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may turn on. If this occurs, return to your
authorized Oldsmobile dealer for service.To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
contribute to clean air. General Motors recommends that
you use these gasolines, particularly if they comply with
the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don't use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn't
be covered under your warranty.

Before closing the hood, be sure all the filler caps are on
properly. Then lift the hood to relieve pressure on the
hood prop. Remove the hood prop from the slot in the
hood and return the prop to its retainer. Then just let the
hood down and close it firmly.
Engine Oil
If the LEVEL light on the
instrument panel comes on,
it means you need to check
your engine oil level
right away.
For more information, see ªLow Oil Level Lightº 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.
The engine oil dipstick is located at the front of the
engine compartment, near the center. The dipstick
handle has a bright, yellow loop design for
easy identification.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.

6-49 Cleaning Vinyl
Use warm water and a clean cloth.

Rub with a clean, damp cloth to remove dirt. You
may have to do it more than once.

Things like tar, asphalt and shoe polish will stain if
you don't get them off quickly. Use a clean cloth and
a vinyl/leather cleaner. See your dealer for
this product.
Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap and wipe dry with a soft cloth. Then, let the
leather dry naturally. Do not use heat to dry.

For stubborn stains, use a leather cleaner. See your
dealer for this product.

Never use oils, varnishes, solvent
-based or abrasive
cleaners, furniture polish or shoe polish on leather.

Soiled or stained leather should be cleaned
immediately. If dirt is allowed to work into the
finish, it can harm the leather.
Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones or
waxes may cause annoying reflections in the windshield
and even make it difficult to see through the windshield
under certain conditions.
Cleaning Interior Plastic Components
Use only a mild soap and water solution on a soft
cloth or sponge. Commercial cleaners may affect the
surface finish.
Cleaning the Built-in Child
Restraint Pad
The built-in child restraint pad is attached to the seat
frame with fastener strips. You can remove the pad and
hand wash it with mild soap and water.
Care of Safety Belts and Built-in
Child Restraint Harness
Keep the safety belts and the built-in child restraint
harness clean and dry.

Vehicle Identification Number (VIN)
This is the legal identifier for your vehicle. It appears on
a plate in the front corner of the instrument panel, on the
driver's side. You can see it if you look through the
windshield from outside your vehicle. The VIN also
appears on the Vehicle Certification and Service Parts
labels and the certificates of title and registration.
Engine Identification
The 8th character in your VIN is the engine code. This
code will help you identify your engine, specifications
and replacement parts.
Service Parts Identification Label
You'll find this label on the inside of the access panel
located on the driver's side of the rear of the vehicle.
It's very helpful if you ever need to order parts.
On this label is:

your VIN,

the model designation,

paint information and

a list of all production options and
special equipment.
Be sure that this label is not removed from the vehicle.

Electrical System
Add-On Electrical Equipment
NOTICE:
Don't add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn't be covered by your
warranty. Some add
-on electrical equipment can
keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker in the instrument panel fuse panel. An electrical
overload will cause the lamps to go on and off, or in
some cases to remain off. If this happens, have your
headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem, be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the instrument panel fuse panel
protect the power windows and other power accessories.
When the current load is too heavy, the circuit breaker
opens and closes, protecting the circuit until the problem
is fixed.
