Acura 2008 MDX - Manual (Page 427)

Check the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
further corrosion.
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
If additional battery maintenance is
needed, see your dealer or a
qualified technician.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s
electrical system. Always disconnect
the negative ( ) cable first, and
reconnect it last.
If the radio fuse is removed, the
audio system will disable itself. The
next time you turn on the radio you
will see ‘‘ENTER CODE’’ in the
frequency display. Use the preset
buttons to enter the digit code (see
page ).
Check the condition of the battery
