Anti-Lock Brakes (ABS) 
Your vehicle has  an advanced electronic braking system that  can help you 
keep it under  control.  When  you start your vehicle  and  begin to drive away, 
you  may  hear  a momentary motor  or clicking noise.  This is  the 
ABS system 
testing  itself. 
Here's  how  anti-lock  works. Let's  say the  road  is wet. You're  driving safely. 
Suddenly  an animal  jumps out 
in front of you. 
You slam on the brakes. Here's  what happens with ABS. 
A computer  senses  that wheels are slowing  down. If one of the wheels  is 
about 
to stop  rolling, the  computer will separately work the brakes  at each 
front  wheel and  at  the rear wheels.  The anti-lock  system can change the 
brake pressure  faster than any driver  could.  The  computer  is programmed  to 
make the most 
of available tire and road  conditions. 
You can steer around  the obstacle while braking hard. 
As you  brake, your  computer keeps receiving  updates on  wheel speed and 
controls braking pressure  accordingly.

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.

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.
