You could  be injured if the vehicles roll.  Set the parking brake firmly 
on each  vehicle.  Put an automatic transmission in PARK (P) or a 
manual  transmission in NEUTRAL (N). If you have a 
four-wheel-drive  vehicle, be sure  the transfer  case is  not in NEUTRAL 
(N). 
3. Turn  off  the  ignition on both vehicles. Turn  off all lights that  aren’t 
needed, and radios.  This 
will avoid sparks and help save both batteries. 
And  it could  save your radio! 
NOTICE: 
If you  leave  your radio  on, it could  be  badly  damaged. The 
repairs  wouldn’t  be  covered  by your warranty. 
4. Open  the hoods and locate the batteries.  Find the positive (+) and 
negative 
(-) terminals on each battery. 
A CAUTION: 
Using  a match  near a battery  can cause battery gas  to  explode. 
People  have been hurt doing  this, and some  have  been  blinded. 
Use 
a flashlight if you  need  more light. 
Be  sure  the batteries  have enough 
water. You don’t  need  to  add 
water to  the Delco Freedom@  battery (or batteries)  installed in 
every  new 
GM vehicle.  But if a battery  has filler  caps,  be sure 
the  right  amount of fluid  is  there. 
If it is low,  add water to take 
care 
of that  first. If you don’t,  explosive  gas could  be  present. 
Battery  fluid contains acid  that can burn  you.  Don’t  get 
it on 
you. 
ff you  accidentally  get it in your  eyes or on your  skin,  flush 
the place  with water  and get  medical  help immediately. 
5. Check  that the jumper  cables don’t have  loose or missing insulation.  If 
they  do, 
you could get  a shock.  The vehicles  could be damaged, too. 
Before you  connect the cables,  here are  some basic things  you should 
know. Positive 
(+) will go to  positive (+) and negative (-) will  go  to 
negative 
(-) or a metal  engine  part. Don’t  connect (+) to (-) or you’ll 
get 
a short that would  damage the battery and maybe  other parts, too.

If the light  comes on at any other time,  use this  chart.  This  light  also  should 
come  on  briefly when 
you  start  your  engine, 
as 
a check.  If it 
doesn’t,  have  it  fixed 
so it will  be there  to 
let  you  know  if you 
ever  do get  water  in 
your  fuel. 
If you drive  when  this warning  light is on, you  can damage your 
fuel  injection  system  and your  engine. 
If the light  comes  on  right 
after  you refuel, 
it means water  was pumped into your  fuel tank. 
Turn 
off your  engine  immediately.  Then, have the water  drained 
at once.

Light stays on: 
1. At  temperatures  above  freezing. 
2. At temperatures  below  freezing.

To Check Coolant 
A CAUTION: 
Turning the  surge  tank  pressure cap when  the engine  and 
radiator  are  hot can allow steam  and scalding liquids to  blow out 
and  burn  you  badly.  Never  turn the  surge  tank  pressure cap 
- 
even a little - when the engine  and  radiator  are  hot. 
When your  engine  is cold,  the coolant  level  should  be at the  COLD  mark, or 
a little higher. 
If this  light  comes  on, it means you’re low on  engine  coolant. 
To Add Coolant 
If you need more  coolant,  add the proper  mix ut the surge tmk, but only 
when  the  engine  is cool.  If the  surge tank is empty, see  “Engine 
Overheating” 
in the  Index  for the proper fill procedure. 
A CAUTION: 
You can  be burned  if  you spill coolant on hot  engine parts. 
Coolant contains ethylene  glycol, and 
it will burn  if the  engine 
parts  are  hot enough.  Don’t  spill  coolant on a hot  engine. 
When  replacing  the pressure  cap, make  sure it is tight.

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  varv. 
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: 
carry passengers and cargo  within recommended  limits. You will find 
these  limits  on your vehicle’s  CertificatiodTire  label.  See  “Loading 
Your  Vehicle“ 
in the Index.

Driving  With  Your  Four-wheel  Drive Vehicle” 
in the Index. 
use the recommended  unleaded fuel.  See “Fuel” in the index. 
Selecting  the  Right  Schedule 
The proper  maintenance  schedule for your vehicle  depends on which  engine 
you  have 
in your vehicle and  how  you  use your vehicle. 
Gasoline  engine  vehicles and diesel  engine  vehicles have different 
maintenance  requirements. 
If you have  a diesel  engine,  follow a schedule 
designated  for  diesel engine  vehicles only.  If  you have 
a gasoline  engine. 
you  must first  determine  whether your  engine has 
a light duty  or  a heavy 
duty  emissions  classification.  Follow a maintenance  schedule designated 
for 
for your  engine.  See  “Engine  Identification” in the Index  to find your 
engine‘s emission  classification.
