If the terminals are severely cor-
roded, clean them with baking soda
and water. Then use a wrench to
loosen and remove the cables f rom
the terminals. Always disconnect the
negative ( ) cable f irst 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. If you need to connect the battery to
a charger, disconnect both cables to
prevent damage to the car’s
electrical system.
If your car’s battery is disconnected
or goes dead, the audio system, the
driver’s window AUTO f unction, and

Battery
266
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
mechanic do the battery
maintenance. Charging the battery with the cables
connected can seriously damage your
car’s electronic controls. Detach the
battery cables bef ore connecting the
battery to a charger.

Put the transmission in Neutral or
Park, and set the parking brake. Open the hood and check the
physical condition of the battery
(see page ). In very cold
weather, check the condition of
the electrolyte. If it seems slushy
or like ice, do not try jump starting
until it thaws.
To jump start your car, f ollow these
directions closely:
If your car’s battery has run down,
you may be able to start the engine
by using a booster battery. Although
this seems like a simple procedure,
you should take several precautions.
You cannot start an Acura with an
automatic transmission by pushing
or pulling it. Turn of f all the electrical acces-
sories: climate control, audio
system, lights, etc.

Attempting to jump start with a f rozen
