Battery
If the terminals are severely cor-
roded, clean them with baking soda
and water. Then use a wrench to
loosen and remove the cables from
the terminals. Always disconnect the
negative ( — ) cable first and recon-
nect it last. Clean the battery termi-
nals with a terminal cleaning tool or
wire brush. Reconnect and tighten
the cables, then coat the terminals
with grease.
Maintenance
If you need to connect the battery to
a charger, disconnect both cables to
prevent damage to the car's electri-
cal system.
On the U.S. EX and Canadian EX-R
models
If your car's battery is disconnected
or goes dead, the audio system will
disable itself. The next time you turn
on the radio you will see "Code" in
the frequency display. Use the
Preset buttons to enter the five-digit
code (see page 99 ).
NOTICE
Charging the battery with the cables
connected can seriously damage
your car's electronic controls.
Detach the battery cables before
connecting the battery to a charger.
