1997 GMC JIMMY maintenance

Finish Damage
Any stone chips. fractures or deep scratches in the finish
should be repaired right away. Bare
metal will corrode
quickly and may develop into
a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas of finish damage can
be corrected
in your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust conh-01
can collect on the underbody. If these xe not removed,
accelerated corrosion (rust) can oxcur
on the underbody
parts such as fuel lines, frame, floor pan and exhaust system
even though they have corrosion protection.
At least every spring, flush these materials from the
underbody
with plain water. Clean any areas where mud
and other debris
can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody car washing system can do
this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces
on your vehicle. This damage
can take two
forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect
in the paintjob causes this, CM will
repair. at no charge to the owner. the surfaces of new
vehicles damaged by this fallout condition
within
I2 months or 12,000 miles (20 000 km) of purchase.

Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle
in good working condition, but also helps the
environment.
All recommended maintenance procedures
are important. Improper vehicle maintenance can even
affect the quality
of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase the level
of emissions from your vehicle. To help protect our
environment. and to keep your vehicle
in good
condition, please maintain your vehicle properly.

How This Section is Organized
The remainder of this section is divided into five parts:
“Part
A: Scheduled Maintenance Services” shows
u:hat
to 11a1:e done md how often. Some of these
services can be complex.
so unless you are technically
q~~alifiecl
and 11ac.e the necessary equiptnent. you should
let your dealer‘s service department or another qdified
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
only 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. “Part
B: Owner Checks and Services”
tells you
what should be checked and when. It also explains
what
you c;m easily do to help keep yo~tr vehicle in
ci ~od condition.
“Part C: Periodic Maintenance Inspections”
explains import;lnt inspections that your
GM dealer’s
service depu-tment or another qualified service center
ShOLlld perforlll.
“Part
D: Recommended Fluids and Lubricants” lists
some products GM reco~ntnends to help keep yo~~r
vehicle properly maintainecl.
‘These products. or their
equivalents. should
be used whether you do the work
yourself
or I~a\;e it done.
“Part
E: Maintenance Record” pro\;ides a place for
you to record the maintenance perfw-riled on yo11r
\:chicle. Whenever any maintenance is perfor~ned. be
sure to write it down in this part. This will help you
deternline when your
next maintenance should be done.
In addition. it is a good idea to keep your tnaintenance
receipts. They
may be needed to ql~alify your vehicle for
warranty repairs.

Part A: Scheduled Maintenance
Services
Using Your Mair mce Schedule A - --
We at General Motors want to help you keep your
vehicle
in 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 all
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 the different ways people LIS~ their GM
vehicles, maintenance needs vary. You may even need
more frequent checks and replacements
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 GM dealer.
This part tells
you the maintenance services YOLI 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 tluids and lubricants
to use are listed in Part D.
Make sure whoever services your vehicle uses these. All
parts should be replaced and all necessary repairs done
before
you or anyone else drives the vehicle.
These schedules are
for vehicles that:
a

limits. You
will find these limits on your vehicle's
