Maintenance  When  Trailer  Towing 
Your vehicle will need service more often when  you’re 
pulling 
a trailer.  See the Maintenance Schedule  for more 
on this. Things  that are especially important  in trailer 
operation  are automatic transaxle fluid (don’t overfill), 
engine 
oil, belts, cooling system, and brake adjustment. 
Each 
of these is covered in this manual, and the Index 
will help  you find  them  quickly.  If you’re trailering,  it’s 
a good idea to review these sections before you start 
your trip. 
Check periodically  to  see that 
all hitch  nuts  and bolts 
are tight.

6. Check that the  jumper  cables  don’t have  loose  or 
missing  insulation. 
If they do, you  could  get  a shock. 
The  vehicles could  be  damaged, too. 
Before  you connect  the  cables,  here  are  some things 
you should  know. Positive 
(+) will go  to  positive (+) 
and negative (-) will  go  to negative (-) or  a  metal 
engine  part.  Don’t  connect 
(+) to (-) or  you’ll  get a 
short  that  would damage  the  battery and maybe other 
parts,  too. 
7. Connect  the red positive (+) cable  to  the positive (+) 
terminal  of the  vehicle  with the dead  battery. Use a 
remote  positive (+) terminal if the vehicle has  one.

3800 V6: Recovery  Tank  Level 
l I I 
The coolant level should  be  at  or above the FULL HOT 
mark. If it isn’t,  you  may  have a  leak  in the radiator 
hoses, heater hoses, radiator, water pump  or somewhere 
else  in the  cooling  system. 
I NOTICE: 
Engine  damage  from  running  your  engine 
without  coolant  isn’t  covered  by  your  warranty. 
If there seems  to  be no leak, with the  engine on, check to 
see  if the electric  engine fan is running. 
If the engine  is 
overheating, the fan should be running. 
If it  isn’t, your 
vehicle needs  service.

~~~ Fuels  in  Foreign  Countries 
If 
you  plan  on driving  in another country outside the 
United States or Canada, unleaded 
fuel may be hard to 
find.  Do not  use leaded gasoline. 
If you  use even  one 
tankful, your emission controls won’t work well or at 
all.  With continuous use, spark plugs can  get fouled, the 
exhaust system can corrode, and your engine oil can 
deteriorate  quickly.  Your  vehicle’s  oxygen sensor will be 
damaged.  All of that  means costly repairs that wouldn’t 
be  covered  by your  warranty. 
To check on  fuel availability, ask an auto club, or 
contact a major oil company that does business in the 
country where you’ll be driving. 
You can  also write us at the following address for 
advice. Just tell  us where you’re going and give your 
Vehicle  Identification Number (VIN).

Engine Oil 
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  easier 
identification. 
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. 
To Check  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.

Automatic  Transaxle Fluid 
When to Check  and  Change 
The  automatic  transaxle  fluid  dipstick  for the 3.1 L V6 
engine is located near the  center of the engine 
compartment,  to  the left 
of the windshield washer fluid 
reservoir.  The  dipstick  for 
the 3800 V6 engine is located 
toward the back 
of the  engine  Compartment, near the 
center.  The dipstick  handle (for both  engines) has 
a 
bright, red  loop  design  for  easier  identification. 
A good time to check your  automatic  transaxle  fluid 
level  is when the  engine oil is changed.  Refer to the 
Maintenance  Schedule to  determine when to change 
your  fluid.  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  retailer 
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. 
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: 
When  outside  temperatures  are above 90°F (32°C). 
At  high speed for quite a while. 
In heavy traffic -- especially in hot  weather. 
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  longer.

3. 
4. 
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:

of the  vehicle,  towards  the middle of 
the  engine  compartment.

To Check  Coolant 
When your  engine is cold,  the coolant level should  be  at 
COLD, or  a  little  higher. When your engine  is  warm, the 
level  should  be  up to 
FULL HOT, or a little higher.
