If  you need to  replace  any  of  your  wheels,  wheel  bolts or 
wheel  nuts,  replace  them only with  new GM original 
equipment  parts.  This  way,  you will be sure  to have the 
Using  the  wrong  replacement  wheels, wheel 
bolts  or  wheel  nuts  on  your  vehicle  can  be 
dangerous. 
It could  affect  the  braking  and 
handling  of  your  vehicle,  make  your  tires  lose 
air  and  make  you  lose  control.  You  could  have 
a  collision  in  which  you  or  others  could  be 
injured.  Always  use  the  correct  wheel,  wheel 
bolts  and  wheel  nuts  for  replacement. 
I 
Notice: The  wrong  wheel  can  also  cause  problems 
with  bearing  life,  brake  cooling,  speedometer  or  odometer  calibration,  headlamp  aim, bumper  height, 
vehicle  ground  clearance  and  tire  or  tire  chain 
clearance  to  the  body  and  chassis. 
See 
Changing a Flat Tire on page 5-70 for more 
information. 
Used Replacement WI els 
Putting  a  used  wheel on your  vehicle  is 
dangerous.  You can’t  know  how  it’s  been  used 
or how  far it’s been  driven. It could  fail  suddenly 
and  cause  a  crash.  If  you  have  to replace  a 
wheel,  use  a  new 
GM original  equipment  wheel. 
Tire Chains 
Notice: 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  front  tires  and  tighten  them  as  tightly 
as  possible  with  the  ends  securely  fastened. 
Drive  slowly  and  follow  the  chain  manufacturer’s 
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.

Electrical System 
Add-on Electrical Equipment 
Notice: Don’t  add  anything  electrical to  your 
vehicle  unless  you  check with your  dealer  first. 
Some  electrical  equipment can damage  your  vehicle 
and  the damage  wouldn’t  be covered  by  your 
warranty.  Some  add-on electrical equipment  can 
keep  other  components  from  working  as  they  should. 
Your vehicle has  an air bag  system.  Before attempting to 
add anything electrical to  your vehicle,  see 
Servicing 
Your  Air Bag-Equipped  Vehicle 
on page 1-76. 
Headlamp Wiring 
The headlamp  wiring is protected by an internal circuit 
breaker  in  the instrument panel fuse  panel.  An electrical 
overload  will cause the  lamps to  go  on and 
off, or in 
some cases  to  remain 
off. If this  happens, have 
your  headlamp wiring checked right away. 
Windshield  Wiper Fuses 
The windshield  wiper motor is protected by  an internal 
circuit  breaker and  a  fuse. If the  motor overheats  due  to 
heavy  snow,  etc.,  the wiper  will stop  until the  motor 
cools.  If the overload  is caused by  some electrical 
problem,  be sure to  get it fixed. 
Power  Windows  and  Other 
Power  Options 
Circuit breakers in the  instrument  panel  fuse  panel 
protect the power  windows  and  other  power  accessories. 
When  the current  load is too  heavy,  the  circuit  breaker 
opens  and closes,  protecting  the  circuit  until  the 
problem  is fixed. 
Fuses  and Circuit  Breakers 
The wiring circuits in  your  vehicle  are  protected  from 
short  circuits by  a  combination  of fuses,  circuit  breakers 
and fusible thermal  links. 
Look at the silver-colored band inside  the  fuse.  If  the 
band  is broken  or  melted,  replace  the  fuse.  Be  sure  you 
replace  a bad  fuse  with  a  new  one 
of the  identical 
size  and rating. 
If  you  ever  have  a  problem  on the  road  and  don’t  have 
a  spare  fuse, you can  borrow  one  that  has  the  same 
amperage  or use  one  of the  spare  fuses  in the 
underhood fuse  block.  Just  pick  some  feature  of your 
vehicle  that you can  get  along  without 
- like  the  radio 
or  cigarette lighter 
- and  use  its  fuse, if it is  the 
right  amperage.  Replace  it  as  soon  as  you  can. 
There are two fuse  blocks in your  vehicle,  the  instrument 
panel fuse  block and  the  underhood  fuse  block.
