If your battery has run down, you may
want to use another vehicle and some
jumper cables to start your Corvette.
But please follow the steps below to
do it safely.
NOTICE:
Ignoring these steps could result
in costly damage to your vehicle
that wouldn’t be covered by your
warranty.
Trying to start your Corvette 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.
Ib Jump Start Your Corvette:
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.
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
Corvette, and the bad grounding could
damage the electrical systems.
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!
I NOTICE:
I
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.

Every new Corvette 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 catalog number shown on the original
battery’s label. For battery replacement,
see your dealer or the Corvette Service
Manual.
To purchase a service manual,
see “Service Publications” in the Index.
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. Contact your
dealer to learn how to
prepare your vehicle for longer storage
periods.
