Acura 2013 MDX - Manual (Page 552)

The sensor on the negative
terminal monitors your vehicles
battery condition.
If there is a problem with the sensor,
you will see a
‘‘CHECK BATTERY
SENSOR ’’ message on the
multiinformation display. Have the
vehicle checked by your dealer.
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.
If additional battery maintenance is
needed, see your dealer or a
qualified technician.
WARNING: Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash your hands after handling.
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.
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt
you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.
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
308 ).
