Battery - Mitsubishi Carisma Owner's Manual

Battery

The condition of the battery is very important
for quick starting of the engine and proper
functioning of the vehicle's electrical system.
Regular inspection and care are especially
important in cold weather.
NOTE
(1) After replacing the battery, the electronic
control system data for the engine, auto-
matic transmission, etc., will be erased.
As a result, the engine speed may be-
come unstable and shift shocks may
occur.
If the engine speed become unstable,
initial engine adjustments will need to be
performed.
Refer to the section "What to do if the
engine speed becomes unstable after
the battery is replaced:" on page 8–22.
Shift shocks will become smoother after
several changes in speed.
(2) Memory data for settings made by the
user may be erased when the battery is
replaced. If this happens, establish the
settings again using the relevant pro-
cedures.

Checking battery electrolyte level
The electrolyte level must be between the
"max" and "min" marks stamped on the out-
side of the battery. Replenish with distilled
water as necessary.
The inside of the battery is divided into sev-
eral compartments; remove the cap from
each compartment and fill to the "max" mark.
Do not over-replenish beyond the "max"
mark because spillage during driving could
cause damage.
Check the electrolyte level at least once
every four weeks, depending on the operat-
ing conditions.
If the battery is not used, it will discharge by
itself with time. Check it once every four
weeks and charge with low current as
necessary.
MAINTENANCE
During cold weather
The capacity of the battery is reduced at low
temperatures. This is an inevitable result of
its chemical and physical properties. This is
why a very cold battery, particularly one that
is not fully charged, will only deliver a fraction
of the starter current which is normally avail-
able.
It is recommended that you have the battery
checked by an authorized MITSUBISHI
M37B003a
dealer before the start of cold weather and,
if necessary, have it charged.
This not only ensures reliable starting, but a
battery which is kept fully charged also has
a longer life.
Disconnection and connection
To disconnect the battery cable, stop the en-
gine, first disconnect the negative (–) ter-
minal and then the positive (+) terminal.
When connecting the battery, first connect
the positive (+) terminal and then the nega-
tive (–) terminal.
