If none of them is true, use the %ong triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs
ht. Driving a vehicle with a fully warmed
engine
under highway conditions causes engine oil
to $re& down dower.
If any one of these is true for you, use the short tripkity
maintenance schedule:
8
Most trips are less than 5 to 13 miles (8 to I 6 km).
This is particularly important when outside
temperatures
are below freezing.
Most trips include extensive id1ir.g (such as frequent
$riving
in stop-and-go traffic).
Most
trips are though 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. Hf any me of these is true for your
vehicle, then
YOU need to change your si1 and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs

Did you know that used engine oil contains certain
ekmer,ts that may
be unhealthy for your skin and csdd
even cause cancer? Don’t let used oil stay on your skin
for very iong. Clean your skin and nails with soap and
water, or a good hznd 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 t-heat 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 coilects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer,
a service station or a local recycling
center for kelp.

''I+he brcadwear grade is a comparative rating based Q~Z
t tze wcx rate of the tire when tested under controlled
conditions
on a specified government test course.
For example, a tire graded 150 would wear one md a
Mf (I U2) times as well on the government course
:H tire graded 100. The relative performance of tires
depends
upon the actual conditions of their use,
however, and may depart significantly from the norm
tErrc to variations in driving habits, service practices
and differences in road characteristics and climate.
'The traction grades, from highest
to !owest, are A, 3,
and C, and they represent the tire's ability to stop ora
wet pavement as measured mder controlled conditions
on specified government test surfaces of asphalt
2nd concrete. A tire marked &: may have poor
traction performance.
Warning: The traction grade assigned
to this tire is based
on
braking (straight alead) traction tests and does not
ifgcllude cornering (turning) traction. heat
and its ability to dissipate heat when tested under
controlled csndidsns on a specified indoor laboratory
test wheel. Sustained
high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive ternperaFure can lead to sudden fire faifwe.
The grade C corresponds to a level of pedomance
which ail passenger cx tires must meet e~nder the
Federal
Motor Vehicle Safety Stmda-d No. i09. Grades
B asci A represent higher levels of perhmance an the
laboratory test wheel than the minimum required by law.
The wheels OR your vehicle were aligned and balanced
careEulIy at the factory to give you the longest tire life
acd best overall performance.
Scheduled wheel alignment
and wheel balancing are not
needed. However, if you notice unusual tire wear or
your vehicle pulling GR~ way OF the other, the akignment
may need
to be reset. If YOU notice your vehicle
vibrating
when driving on a smooth road, your wheels
may need
to be rebalaaaced.

The remainder of this section is divided into five pms:
”Part A: Scheduled Maintenance Services” shows
what to have done and how oftec. Some of these
services
can be complex, so unless you are technically
qualified and have the necessary equipnent, you should
let your dealer’s service department
or another qualified
service center
do these jobs.
Performing maintenance work on a vehicle can
be dangerous.
In trying to do some Jobs, you can
be seriously injured.
Do your own maintenance
work O~Y if you have the required know-how
and the proper tools and equipment for the job.
If you have any doubt, have a qualified
technician
do the work.
If you are skilled enough to do some work on your
vehicle, you will probably want
to get the service
information. See “Service and Owner Publications”
in the Index.
“Part 8: Owner Cheeks and Services” tells you
what should be checked and when.
It also explains
what YOU can easily do to help keep your vehicle in
good condition.
“Part C: Periodic Maintenance Inspections”
explains important inspections that your deater’s
service department or another quaiifled service center
should perfom.
“Part D: Recommended Fluids and Llph~ricipn~’’
lists some recommended products to hcBp keep your
vehicle properly
maintained. T’kzesc 19n~lucts, or their
equivalents, should
be used wlacikct. you do the work
yourself or have

“Past E: Maintenance Record’’ provides a,place for
you to record the ~naintcrrance performed on your
vehicle. Whenever any n:aintcnancc is performed, be
sure to write it down in Ffris part. ’his will help you
determine when your next nraintenance should be done.
In addition,
it is ;L good idca to keep your maintenance
receipts.
They may be rleedcd to qualify your vehicle
for warranty repairs.

We at General Motors want to kelp you keep your
vehicle
ia good working condition. But we don’t
know exactly
how you’ll drive it. You may drive very
short distances only
a few times a week. Or you may
drive long distances
aEB the time in very hot, dusty
weather.
You may use your vehicle in making deliveries.
Or
YOU may drive it to work, to do errands or in
many other ways.
Because of all thc different ways people use their
vehicles, maintenance
rreeds vary. You may even
need
more frequent checks and repiacements than
you’ll
find in the schedules in this section. So please
read this section
and note how you drive. If you have
any questions on how to keep your vehicle in
good
condition, see your Buick dealer.
This part tells
you the maintenance services you should
have done and when you should schedule them. If you
go to your dealer for your service needs, you’ll know
that GM-trained and supported service people will
perform the work
using genuine GM parts. The
proper fluids and
lubricants to use are listed in
Part D. Make sure whoever services your vehicle
uses these. All
parts should be replaced and a1
necessary repairs done before you
or anyone else
drives the vehicle.
These schedules
are for vehicles that:
cany passengers and cargo within recommended
limits.
You will find these limits on your vehicle’s
