extended period, such as in heavy
traffic.

will discharge grad ually even when
the vehicle is not in use, due to nat-
ural discharge and the draining
effects of certain electrical appli-

time, the battery may discharge,
and the engine may be unable to
start. (The battery recharges auto-
matically during driving.)

tery is discharged. Use the wire-
less remote control or the
mechanical key to lock or unlock
the doors.

first attempt after the battery has
recharged but will start normally
after the second attempt. This is
not a malfunction.

rized by the vehicle. When the
battery is reconnected, the system
will return to the mode it was in
before the bat tery was dis-
charged. Before disconnecting the
battery, turn the engine switch off.
If you are unsure what mode the
engine switch wa s in before the
battery discharged, be especially
careful when reconnecting the
battery.
■When replacing the battery

same as the previous one (LN1),
