2002 CHEVROLET VENTURE relay

5-5
The terminal is located
under a tethered cap
at the front of the
underhood fuse and
relay center. See
ªEngine Compartment
Overviewº in the Index
for more information
on location.
Squeeze the tabs and pull up on the cap to access the
remote positive (+) terminal. You should always use
the remote positive (+) terminal instead of the
positive (+) terminal on your battery.
CAUTION:
An electric fan 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.
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 battery has enough water. You don't
need to add water to the ACDelco
battery
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. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
