1. Engine  Oil  and  Filter  Change* - 
Always  use SH or SG  Energy 
Conserving 
I1 oils  of proper  viscosity. 
The 
“SH” or “SG” designation  may 
be  shown alone 
or in combination 
with others, such  as “SH/CD,” 
“SH, 
SG, CD,” “SG/CD,”  etc.  To 
determine  the preferred  viscosity  for 
your  vehicle’s  engine (e.g., 
SAE 5W- 
30 or  SAE 10W-30),  see 
Engine  Oil 
in the Index. 
2. Chassis  Lubrication - Lubricate 
suspension and steering  linkage. 
Lubricate  the transaxle  shift  linkage, 
and  parking  brake cable  guides, 
underbody  contact points and 
linkage. 
3. Tire  and  Wheel  Rotation  and 
Inspection 
- For  proper  wear and 
maximum  tire life,  rotate  your tires 
following  the instructions  in this 
manual.  See 
Tires,  Inspection E. 
Rotation in  the Index. Check the 
tires  for uneven  wear 
or damage.  If 
you  see  irregular  or premature  wear, 
check  the wheel  alignment.  Check  for 
damaged  wheels  also. 
Engine  Accessory  Drive  Inspection 
- Inspect the drive  belt  for cracks, 
fraying,  wear  and proper tension. 
Replace  as needed.

inhibitor  level and maintains proper ’ 
engine operating temperature. 
Inspect  hoses 
and replace if they are 
cracked,  swollen  or  deteriorated. 
Tighten  screw-type  hose clamps. 
Clean  the outside  of the  radiator and 
air  conditioning  condenser. Wash  tht

Now and then,  make  sure all your belts, buckles,  latch plates,  retractors,  anchorages  and 
reminder  systems are working properly. Look  for any loose  parts or damage. 
If you  see anything 
that  might keep 
a restraint  system from doing its job, have  it repaired. 
Inspect  the  front  and  rear  suspension 
and steering system  for damaged, loose or missing  parts, 
signs  of wear,  or  lack of lubrication.  Inspect  the power  steering lines  and hoses for proper 
hookup,  binding, leaks,  cracks, chafing,  etc. Clean  and  then  inspect  the  drive axle boot seals for 
damage,  tears  or leakage. Replace seals  if necessary. 
Inspect  the complete  exhaust  system.  Inspect the body  near the exhaust  system. Look for broken, 
damaged, missing  or out-of-position  parts  as well 
as open  seams,  holes,  loose connections,  or 
other  conditions  which  could cause  a  heat  build-up  in the  floor  pan  or  could let exhaust  fumes 
into  the  vehicle. See 
Engine Exhaust in the Index. 
Inspect  the  throttle  linkage for interference  or binding,  and for damaged  or missing  parts. 
Replace  parts as needed. 
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. 
NOTE: 
A low  brake  fluid  level  can  indicate  worn  disc brake  pads which  may  need to be serviced. 
Also, if the  brake system  warning light stays  on or comes  on,  something  may be wrong with  the 
brake  system. See  the 
Index under Brake  System  Warning  Light. If your anti-lock brake  system 
warning  light stays  on  or comes  on, something  may be wrong  with the anti-lock brake  system. 
See  the 
Index under Anti-Lock  Brake  System Wawing Light.
