Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.
9. Replace the wheel nuts
with the cone end
of the
nuts toward the wheel.
Tighten each nut by
hand or with the wheel
wrench until the wheel
is held against the hub.
10. Lower the vehicle by rotating the wheel wrench
counterclockwise. Lower the jack completely.

If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution. is
If you
let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transaxle or other parts of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little as possible. Don’t
spin the wheels above 35 mph (55 kdh) as shown
on the speedometer.
NOTICE:
Spinning your wheels can destroy parts of your
vehicle
as well as the tires. If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels.
If your vehicle
has the Enhanced Traction System, you should turn
the system off. (See “Enhanced Traction System”
in the Index.) Then
shift back and forth between
REVERSE (R) and a forward gear (or with a manual
transaxle, between F’IRST
(1) or SECOND (2) and
REVERSE (R)), spinning the wheels as little as
possible. Release the accelerator pedal while you shift,
and press lightly on the accelerator pedal when the
transaxle is in gear. If that doesn’t get you out after
a
few tries, you may need to be towed out. If you do
need to be towed out, see “Towing Your Vehicle”
in the Index.

Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove
it again,
keeping the tip down, and check the level.
I
3100 Engine
The engine oil dipstick handle is yellow. The dipstick
handle for the
2.4L engine is located behind the engine.
The dipstick for the
3100 engine is located in front of
the engine, behind the fan.
Turn
off the engine and give the oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level.

Engine Oil Additives
Don’t add anything to your oil. Your Oldsmobile retailer is
ready to advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short trip/city
maintenance schedule:
0
0
0
0
0
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. If any
one of these is true for your
vehicle, then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first.
If none of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (1 2 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with
a fully warmed
engine under highway conditions causes engine oil to
break down slower.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from
the filter before disposal. Don’t ever dispose of oil
by putting
it in the trash, pouring it on the ground, into
sewers, or into streams
or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If
you have a problem properly disposing of your used oil,
ask your retailer, a service station or a local recycling
center for help.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services”
in the Index.
How to Check
Because this operation can be a little difficult, you may
choose
to have this done at your Oldsmobile retail
facility Service Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading
on the dipstick.
I NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts
or exhaust system parts, starting a fire.
Be sure to
get an accurate reading if
you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
0 When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
In heavy traffic -- especially in hot weather.
0 While pulling a trailer.

To get the right reading, the fluid should be at normal
operating temperature, which is 180°F to 200"
F
(82°C to 93°C).
Get the vehicle warmed up by driving about 15 miles
(24
km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F (lO"C), you may have
to drive 1Qnger.
the Fluil
Park your vehicle on a level place. Keep the
engine running.
With the parking brake applied, place the shift lever
in
PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing
for about
three seconds in each range. Then, position the shift
lever in PARK
(P).
Let the engine run at idle for three to five minutes. Then, without shutting
off the engine, follow these steps:
1. The
automatic transaxle dipstick handle is red.
Pull out the dipstick and wipe it with a clean rag or
paper towel.
2. Push it back in all the way, wait three seconds and
then pull
it back out again.

Manual Transaxle Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual transaxle
doesn’t require changing.
How to Check
Because this operation can be a little difficult, you may
choose
to have this done at your Oldsmobile retail
facility Service Department.
E you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
I NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall
on hot engine parts
or exhaust system parts, starting a fire. Be sure to
get an accurate reading if you check your
transaxle fluid.
Check the fluid level only when your engine is off, the
vehicle is parked
on a level place and the transaxle is cool
enough for you to rest your fingers on the
transaxle case.
Then, follow these steps:
1. The manual transaxle dipstick handle is white and is
located behind the engine. Flip
the handle up and
then pull
out the dipstick and clean it with a rag or
paper towel.
2. Push it back in all the way and remove it.

Don’t include the compact spare tire in your tire rotation. [t’s Time for New
After the tires have been rotated, adjust the front and
rear inflation pressures as shown
on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in
the Index.
I
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after
a time. The wheel could come off and cause
an accident. When
you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use
a cloth or a paper towel to do this; but be
sure to use
a scraper or wire brush later, if you
need to, to get all the rust or dirt off. (See
“Changing
a Flat Tire” in the Index.)
kc
One way to tell when it’s
time for new tires is
to
check the treadwear
indicators, which will
appear when your tires have
only
1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
0 You can see cord or fabric showing through the

0 The tire has a bump, bulge or split.
0 The tire has a puncture, cut or other damage that
can’t be repaired well because
of the size or location
of the damage.
