Push  the  button  at  the 
top  of  the  steering 
column  all  the  way 
down  to make 
your 
front  and rear  turn 
signals flash  on and 
off. 
Your  hazard warning  flashers work no matter what position  your  key  is in, 
and even if the key  isn’t in. 
To turn off the flashers,  push the button until the first click and release. 
When the hazard warning  flashers are on,  your turn signals won’t work. 
Other  Warning  Devices 
If you  carry reflective triangles,  you can use them  to  warn  others. Set one  up 
at  the  side  of the  road  about 
300 feet (100 m) behind your vehicle. 
Jump Starting 
If your  battery  (or batteries) has  run down,  you may want to  use another 
vehicle  and some  jumper  cables 
to start your vehicle.  But please follow the 
steps below to  do it safely. 
A CAUTION: 
Batteries  can  hurt  you.  They  can  be  dangerous  because: 
They  contain acid that  can burn you. 
They  contain  gas  that  can  explode or ignite. 
0 They  contain  enough  electricity  to  burn you. 
If you  don’t  follow  these  steps exactly,  some  or  all  of  these things 
can hurt  you.

A CAUTION: 
If your vehicle  has air conditioning,  the auxiliary electric  fan 
under  the  hood can 
start up even  when  the engine is not  running 
and  can injure  you.  Keep  hands, clothing  and 
tools away from 
any underhood electric  fan.

NOTICE: 
Ignoring these steps could result  in  costly  damage to your 
vehicle  that wouldn’t  be  covered  by  your vehicle  warranty. 
Trying  to  start  your vehicle  by  pushing or pulling it  could 
damage your  vehicle,  even  if  you  have a manual transmission. 
And  if  you  have an automatic transmission, 
it won’t  start  that 
way. 
To Jump Start Your Vehicle 
1. Check  the other  vehicle.  It must have a 12-volt  battery  with  a negative 
ground  system. 
NOTICE: 
If the  other  system  isn’t  a 12-volt  system  with  a negative 
ground, both  vehicles can be damaged. 
If you  have  a  diesel engine  vehicle  with two batteries  (or more), you 
should  know before  you begin  that,  especially in cold weather, you  may 
not be  able  to  get  enough  power  from a  single  battery 
in another 
vehicle  to  start your  diesel  engine. 
If your vehicle  has more than  one battery,  use the battery  that’s on the 
passenger  side 
of the vehicle - this will  reduce  electrical  resistance. 
2. Get  the  vehicles  close  enough so the jumper  cables can reach,  but  be 
sure  the vehicles aren’t  touching  each other. 
If they are, it could  cause  a 
ground  connection  you don’t  want. 
You wouldn’t  be  able  to start your 
vehicle,  and the bad  grounding could damage 
the electrical  systems.

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.

A CAUTION: 
Fans  or  other  moving  engine  parts  can  injure  you  badly.  Keep 
your  hands  away  from  moving  parts  once  the  engines  are running. 
6. Connect  the red  positive (+) cable  to the positive (+) terminal of the 
vehicle with the dead battery. Use  a remote positive 
(+) terminal if the 
vehicle has  one. 
Dead  Battery (+) Good Battery (+)

7. Don’t let the  other  end touch  metal.  Connect  it to the positive (+) 
terminal of the good battery. Use  a  remote positive (+) terminal if the 
vehicle  has one. 
8. Now connect  the black  negative (-) cable to the good battery’s negative 
(-) cable. 
Don‘t 
let the  other  end touch  anything until  the next step.  The  other  end 
of the  negative  cable DOESN’T go to the dead battery.  It goes  to a 
heavy unpainted  metal part of the vehicle  with the dead battery.

Attach the  cable  at leas1  18  inches (45 cm) away from  the dead battery, 
but not near  engine parts that move.  The electrical connection is just as 
good  there,  but the  chance  of sparks  getting  back to the battery is much 
less. 
Now  start the vehicle  with the good  battery and  run the engine  for 
awhile. 
Try  to start the vehicle 
with the  dead battery. 
If it won’t start after  a  few tries, it probably  needs service.

Battery 
Every new GM vehicle  has a Delco Freedom@  battery. You never have to 
add water to  one of these. When  it’s time  for a new battery,  we recommend 
a  Delco  Freedom@  battery. Get one that has the replacement  number  shown 
on the original battery’s  label. 
Vehicle Storage 
If you’re not going  to drive  your vehicle  for 25 days  or more. take off the 
black,  negative (-) cable  from  the battery.  This will help keep your battery 
from  running  down. 
A CAUTION: 
Batteries  have  acid  that  can  burn  you  and  gas  that  can  explod\
e. 
You can  be  badly  hurt  if  you  aren’t  careful.  See  “Jump  Start\
ing’’ 
in  the  Index  for  tips  on  working  around  a  battery  without 
getting  hurt. 
Contact  your dealer  to  learn  how  to prepare your vehicle for longer storage 
periods. 
Bulb  Replacement 
Before  you replace  any bulbs. be sure that all the lamps are off and  the 
engine  isn’t running. 
Sealed  Beam  Headlamps 
I. Remove  the four 
screws from the 
headlamp  retainer. 
2. Pull the  headlamp 
out and  remove 
the retainer.

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 
in the 
wiring  itself.  This  greatly  reduces 
the chance of fires  caused by electrical 
problems.  See “Fuses  and Circuit  Breakers’’ 
in the Index  for more 
information. 
Headlamps 
The headlamp  wiring is protected by a  circuit breaker in the lamp  switch. 
An  electrical  overload  will cause 
the lamps to flicker  on and off, or in some 
cases  to  remain 
off. If this  happens,  have  your  headlamp  wiring checked 
right  away. 
Windshield  Wipers 
The  windshield  wiper motor  is protected  by a clrculc DreaKer  ana a ruse. 11 
the motor  overheats due to heavy  snow, etc., the wiper  will stop  until the 
motor  cools.  Although  the  circuit  is protected  from electrical  overload, 
overload  due to heavy  snow,  etc., may  cause  wiper  linkage  damage.  Always 
clear  ice  and heavy  snow  from  the the windshield  before  using  the 
windshield  wipers. If the  overload 
is caused  by some  electrical  problem and 
not snow,  etc., be sure 
to get it fixed. 
Power  Windows and Other  Power  Options 
Circuit  breakers in the  fuse  panel  protect the power windows  and  other 
power  accessories.  When  the current  load is too  heavy, the  circuit breaker 
opens  and  closes.  This  protects  the circuit 
until the current  load returns to 
normal or the  problem  is  fixed. 
Trailer  Wiring  Harness 
The standard  seven-wire  trailer  wiring  harness is protected  by an in-line 
fuse  in the  battery  feed wire.  This  fuse  is near the  junction  block. See 
“Trailer Wiring Harness”  in the  Index  for  more  information.
