The access  door for  the  remote oil filter  is  in  the  steering 
linkage  shield  assembly  located  under  the  radiator 
support.  Twist  the  screw  to unlock  or lock  the  door. 
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  dealer,  a  service station or a  local  recycling 
center for help.

If the  level  is  below  the  bottom of the  filler  plug hole, 
you’ll  need to add some  lubricant.  Add  enough  lubricant 
to raise  the level to the  bottom of the filler  plug  hole. 
What  to  Use 
Refer  to the Maintenance  Schedule to determine what 
kind 
of lubricant to use.  See “Recommended  Fluids and 
Lubricants”  in  the  Index. 
Four-wheel Drive 
Most  lubricant  checks in this section  also apply  to 
four-wheel-drive  vehicles.  However,  they  have  two 
additional  systems  that  need  lubrication.

When to Check Lubricant 
Refer  to the  Maintenance  Schedule to  determine  how 
often 
to check the lubricant.  See “Periodic  Maintenance 
Inspections” 
in the  Index.

NOTICE: 
If your vehicle  has P235/75R15,  P23970R15, 
P235/55R16  or 3lxlO.5OR15LT/C size  tires,  don’t 
use  tire  chains.  They  can  damage  your  vehicle. 
If you have  other  size  tires,  use  tire  chains  only 
where  legal  and only  when  you must.  Use only 
SAE Class “S” type  chains  that  are  the  proper 
size  for  your  tires. Install  them  on  the  drive  axle 
tires  (four-wheel-drive  vehicles can use chains  on 
both  axles)  and  tighten  them  as  tightly as possible 
with  the  ends  securely  fastened.  Drive  slowly and 
follow  the  chain  manufacturer’s  instructions. 
If 
you can  hear  the  chains  contacting  your  vehicle, 
stop  and  retighten  them. 
If the  contact  continues, 
slow  down  until  it  stops.  Driving  too  fast  or 
spinning  the  wheels with chains  on will  damage 
your  vehicle. 
Appearance  Care 
Remember,  cleaning  products  can be  hazardous.  Some 
are  toxic.  Others can  burst into flame  if  you  strike  a 
match  or get  them 
on a  hot part of the  vehicle.  Some  are 
dangerous  if  you  breathe  their  fumes in  a  closed  space. 
When 
you use  anything  from a  container  to clean  your 
vehicle,  be  sure to  follow  the manufacturer’s  warnings 
and  instructions.  And  always  open  your  doors  or 
windows  when  you’re  cleaning  the  inside. 
Never use  these  to clean  your  vehicle: 
0 Gasoline 
0 Benzene 
0 Naphtha 
0 Carbon  Tetrachloride 
0 Acetone 
0 Paint Thinner 
0 Turpentine 
0 Lacquer  Thinner 
0 Nail  Polish  Remover 
They can  all be hazardous 
-- some  more  than 
others 
-- and  they  can all damage  your  vehicle,  too.

Downloaded from www.Manualslib.com manuals search engine Part A: Scheduled  Maintenance 
Services 
Using  Your Maintenance  Schedule 
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  use  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  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  all 
necessary  repairs  done  before  you  or anyone  else 
drives  the  vehicle. 
These schedules are  for vehicles  that: 
0 
carry passengers  and cargo  within  recommended 
limits.  You will  find  these limits  on your  vehicle’s 
Certification/Tire label. See  “Loading Your Vehicle” 
in  the Index. 
are  driven  on reasonable  road surfaces  within legal 
driving  limits. 
are  driven  off-road  in 
the recommended manner. See 
“Off-Road  Driving With  Your  Four-Wheel-Drive 
Vehicle’’  in  the  Index. 
use  the  recommended fuel. See  “Fuel”  in  the  Index. 
Selecting the Right  Schedule 
First  you’ll  need to decide which  of the two schedules  is 
right  for your  vehicle.  Here’s  how  to  decide which 
schedule to follow: 
7-3   

Downloaded from www.Manualslib.com manuals search engine Drive  Axle  Service 
Check readfront  axle fluid  level  and  add  as  needed. 
Check  constant  velocity  joints and  axle  seals  for leaking. 
Transfer  Case (Four- Wheel Drive) 
Inspection 
Every 12  months  or at oil  change  intervals,  check  front 
axle  and  transfer  case and add  lubricant  when  necessary. 
Check  vent  hose  at  transfer case for  kinks  and  proper 
installation.  More frequent  lubrication  may be  required 
on off-road  use. 
Brake  System  Inspection 
Inspect  the  complete  system. Inspect  brake  lines and 
hoses  for proper  hook-up,  binding,  leaks, cracks, 
chafing,  etc. Inspect  disc brake  pads  for wear  and  rotors 
for surface  condition.  Also  inspect 
drum brake linings 
for  wear  and  cracks. Inspect  other brake  parts,  including 
drums,  wheel  cylinders, calipers,  parking  brake,  etc. 
Check  parking  brake  adjustment.  You  may need  to  have 
your  brakes  inspected  more  often  if your  driving  habits 
or conditions  result  in  frequent  braking.
