terminal surfaces to help prevent
corrosion from forming.
Check the tightness of the cables
to the battery post by hand. It may
be necessary to tighten the clamp
with a suitable wrench.

cleaned with a damp cloth. Ensure
that all high voltage wires are
firmly attached to the coil pack
and that the other ends are firmly
seated over each spark plug.
Other electrical systems
Wiring, lighting and aftermarket
electrical equipment should be
checked monthly for proper
routing, deterioration or chafing on
other components.

Special service vehicles are
equipped with a maintenance-free
battery which does not require the
addition of water or other regular

Installing aftermarket equipment
When installing aftermarket
equipment, avoid using fasteners
that are too long for the
application or are in an area that
might damage other vehicle
components (i.e., wiring, brake
lines, fuel tank and lines,
powertrain components exhaust
system, suspension, etc.).
Do not make electrical connections
to vehicle electrical systems not
specifically designed for
aftermarket equipment installation.
Do not install and components into
the Powertrain control module

this system may affect engine and
transmission operation. As an
example, connection of
aftermarket electrical equipment
into the brake light circuit or any
other circuit which is connected to
the PCM, anti-lock brake
computer, air bag system,
transmission or any other vehicle
system may cause vehicle
malfunction.
