more  information. 
Exhaust System 
To help prevent damage  to  your exhaust  system, do not  continue  to drive 
your vehicle  if  you notice: 
Engine misfiring 
Loss of performance 
Other  unusual operating  conditions 
Have your  engine and exhaust system serviced  regularly. 
Three- Way Catalytic  Converter  (gas  engines) 
Your  vehicle’s  three-way  catalytic converter  is  designed to reduce the 
pollutants in your  vehicle’s exhaust. Use  only  unleaded fuel  in your vehicle. 
If  you  use  leaded fuel,  you could damage  your  three-way  catalytic converter 
and  other  engine  components. 
Three- Way Catalytic  Converter  (diesel  engines) 
Your  vehicle’s  three-way  catalytic converter  is  designed to reduce  the 
particulates  in your  vehicle’s  exhaust. If your  vehicle’s  three-way  catalytic 
converter  ever  needs to  be replaced,  it  must  be replaced  with a three-way 
catalytic  converter  intended for use  with  diesel engines  only.

vehicles  and  diesel  engine  vehicles  below 
8,500 lbs. GVWR) 
Gasoline  Engines 
This  system has  an oxygen sensor (02) that  helps keep your  engine’s 
air-fuel  mixture  at a proper  level.  Use  only  unleaded fuel in  your vehicle.  If 
you  use leaded  fuel,  you could damage  your oxygen sensor 
(02) and 
three-way  catalytic converter. 
Diesel  Vehicles  Below S,5UU LBS. GVWR 
This system monitors  engine speed and throttle position.  It adjusts exhaust

Lap  and  Shoulder  Belts  Condition  and  Operation - Inspect  belt system, 
including  webbing,  buckles,  latch  plates,  retractors,  guide  loops\
  and 
anchors. Have 
a belt  assembly  replaced if the webbing  has  been  cut  or 
otherwise damaged. 
Body Lubrication  Service - Lubricate  all  body  door hinges  with  engine 
oil. 
Also lubricate the tailgate,  tailgate  handle  pivot  points,  and  tailgate 
mounted  spare tire  carrier  (if  equipped). Lubricate  the  body  hood, 
fuel door 
and  rear  compartment  hinges, latches and  locks  including  interior  glove box 
and  console doors,  and  any folding seat  hardware.  Lubricate  the  hood  safety 
lever  pivot  and  prop rod  pivot.  More  frequent  lubrication  may  be  required 
when  exposed  to 
a corrosive  environment. 
Periodic  Maintenance  Inspections - Listed  below  are inspections  and 
services  which  should  be  performed  at  least  twice 
a year (for instance  each 
spring  or fall).  You should  let  your 
GM dealer’s  service  department  or other 
qualified  service center  do 
these jobs. Make sure  any  necessary  repairs  are 
completed  at once. 
Steering  and  Suspension  Inspection? - Inspect  front  and  rear suspension 
and  steering  system  for  damaged, loose or missing  parts,  signs 
of wear  or 
lack  of  lubrication.  Inspect  power  steering  lines  and  hoses  for proper 
hook-up,  binding,  leaks,  cracks,  chafing, etc. Lubricate the  steering  linkage. 
Accelerator  Control  System - On gasoline  engines,  lubricate the pivot  at 
the 
TBI throttle  lever  stud  with  engine oil. Do not oil any  accelerator  or 
cruise  control  cables. Replace  any  cables that  have  high  effort  or excessive 
wear. 
Exhaust  System  Inspection - Inspect  the  complete system  including  the 
three-way  catalytic converter.  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  buildup 
in the  floor  pan or could let exhaust  fumes seep into the 
passenger  compartments. 
Drive  Axle  Service? - Check  readfront  axle tluid  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.  Oil  the  control  lever  pivot  point  and  all  exposed control 
linkage.  Check 
vent hose  at  transfer  case for kinks  and  proper  installation. 
More frequent  lubrication  may  be  required  on  heavy-duty or off-road  use. 
?A fluid  loss in these  systems  may indicate  a problem.  Have  them  inspected 
and  repaired  at  once.
