■Starting the engine when the
battery is discharged
The engine cannot be started by
push-starting.
■To prevent battery discharge
●Turn off the headlights and the
audio system while the engine is
off.
●Turn off any unnecessary electri-
cal components when the vehicle
is running at a low speed for an
extended period, such as in heavy
traffic.

discharged
Information stored in the ECU is
cleared. When the battery is
depleted, have the vehicle
inspected at your Toyota dealer.
■When removing the battery ter-
minals
When the battery terminals are

the ECU is cleared. Before remov-
ing the battery term inals, contact
your Toyota dealer.
■Charging the battery
The electricity stored in the battery
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-
ances. If the vehicle is left for a long
time, the battery may discharge,
and the engine may be unable to
start. (The battery recharges auto-
matically during driving.)
■When recharging or replacing
the battery
●In some cases, it may not be pos-
sible to unlock the doors using the
smart key system when the bat-
tery is discharged. Use the wire-
less remote control or the
mechanical key to lock or unlock
the doors.
●The engine may not start on the
first attempt after the battery has
recharged but will start normally
after the second attempt. This is
not a malfunction.
●The engine switch mode is memo-
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.
