2. Press the button in the middle ofthe wiper arm connector and pull
the wiper blade away from the
arm connector.

Backglass Wiper Blade
To replace the backglass wiper
blade:
1. Pull the wiper blade assembly away from the backglass.
The backglass wiper blade will
not lock in a vertical position
so care should be used when

2. Rotate the wiper blade assembly, hold the wiper arm in
position, and push the blade
away from the wiper arm.
3. Replace the wiper blade.
4. Return the wiper arm and blade assembly to the rest position on

10-84 Vehicle Care
Notice:If the radio or other
accessories are left on during
the jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories
when jump starting the vehicle.
3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all lamps that are not
needed. This will avoid sparks
and help save both batteries.
And it could save the radio!
4. Open the hoods and locate the positive (+) and negative (−)
terminal locations on the
other vehicle. Your vehicle
has a remote positive (+) and
a remote negative (−) jump
starting terminal. See Engine
Compartment Overview on
page 10‑6 for more information
on the terminal locations.{WARNING
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 do not need
to add water to the ACDelco
®
battery (or batteries) installed in
your new 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 do not, explosive
gas could be present.
Battery fluid contains acid that
can burn you. Do not 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.
{WARNING
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.
5. Check that the jumper cables do not 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 (+) or to a remote
positive (+) terminal if the vehicle
has one. Negative (−) will go to a
heavy, unpainted metal engine
part or to a remote negative (−)
terminal if the vehicle has one.

useful life. We, however,
urge that all recommended
maintenance services be
performed at the indicated
intervals and the maintenance
