Acura 2011 TL - Manual (Page 546)

To see the battery label, remove the
left side engine compartment cover
(see page
).
Check the terminals for corrosion (a
white or yellowish powder) after
removing all engine compartment
covers (see page
). To remove
corrosion, 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 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 your vehicle’s battery is
disconnected, or goes dead, the time
setting may be lost. To reset the time,
see page
.
If your vehicle’s battery is
disconnected or goes dead, the audio
system may 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 code (see
page ).
The navigation system will also
disable itself. The next time you set
to the ON mode, the system will
require you to enter a PIN before it
can be used. Refer to the navigation
system manual.
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
If additional battery maintenance is
needed, see your Acura dealer or a
qualified technician.
