Jump Starting
If your battery has run down, you may want to
use another vehicle and some jumper cables to start
your vehicle. But please use the following steps to
do
it safely.
NOTICE:
Ignoring these steps could result in costly damage
to your vehicle that wouldn’t be covered by your
vehicle warranty.
Don’t try to start your vehicle
by pushing or
pulling it. This could damage your vehicle, even if
you have a manual transmission. And if you have
an automatic transmission, it won’t start that
way.

dangerous because:
They contain acid that can burn you.
They contain gas that can explode or ignite.
They contain enough electricity to burn you.
If you don’t follow these steps exactly, some or all
of these things can hurt you.

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the ve.hicles 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.
To avoid the possibility
of the vehicles rolling,
set the parking brake firmly on both vehicles
involved
in the jump start procedure. 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. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets,
if you have this
option. Turn
off all lamps that aren’t needed as well
as radios. This will avoid sparks and help save both
batteries.
In addition, it could save your radio!

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

explosive gas could be present.
Battery fluid contains acid that can burn you.
Don’t get it on you.
If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.

missing insulation. If they do, you could get a shock.
