be used to operate the electrical
accessories and to display some
instrument panel cluster warning
and indicator lights. This position can also be used for service and
diagnostics, and to verify the
proper operation of the malfunction
indicator lamp as may be required
for emission inspection purposes.
The switch stays in this position
when the engine is running. The
transmission is also unlocked in this
position on automatic transmission
vehicles.
If you leave the key in the ACC/

When to Check Lubricant
Refer to the Maintenance Schedule
to determine how often to check
the lubricant. See Maintenance
Schedule on page 11‑3. How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.

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

light.
(Continued)
WARNING (Continued)
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.
