■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.
■When the battery is removed or
discharged
●Information stor ed in the ECU is
cleared. When the battery is
depleted, have the vehicle
inspected at you r Toyota dealer.
●Some systems may require initial-
ization. ( P.395)
■When removing the battery ter-
minals
When the battery terminals are
removed, the information stored in
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.
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
●Use a battery that conforms to
European regulations.
●Use a battery that the case size is
same as the previous one (LN1),
20 hour rate capacity (20HR) is

7
When trouble arises
equivalent (45Ah) or greater, and
performance rating (CCA) is
equivalent (307A) or greater.
• If the sizes differ, the battery can- not be properly secured.
• If the 20 hour rate capacity is low,
even if the time period where the
vehicle is not used is a short time,
the battery may discharge and the
engine may not be able to start.
●For details, consu lt your Toyota
dealer.
WARNING
■When removing the battery
terminals
Always remove the negative (-)
terminal first. If the positive (+) ter-
minal contacts any metal in the
surrounding area when the posi-
tive (+) terminal is removed, a
spark may occur, l eading to a fire
in addition to electrical shocks
and death or serious injury.
■Avoiding battery fires or
explosions
Observe the following precautions
to prevent accidentally igniting the
flammable gas that may be emit-
ted from the battery:
●Make sure each jumper cable is
connected to the correct termi-
nal and that it is not unintention-
ally in contact with any other
than the intended terminal.
●Do not allow the other end of
the jumper cable connected to
the “+” terminal to come into
contact with any other parts or
metal surfaces in the area, such
as brackets or unpainted metal.
●Do not allow the + and - clamps
of the jumper cables to come
into contact with each other.
●Do not smoke, use matches,
cigarette lighters or allow open
flame near the battery.
■Battery precautions
The battery contains poisonous
and corrosive acidic electrolyte,
while related parts contain lead
and lead compounds. Observe
the following precautions when
handling the battery:
●When working with the battery,
always wear safety glasses and
take care not to allow any bat-
tery fluids (acid) to come into
contact with skin, clothing or the
vehicle body.
●Do not lean over the battery.
●In the event that battery fluid
comes into contact with the skin
or eyes, immediately wash the
affected area with water and
seek medical attention. Place a
wet sponge or cloth over the
affected area until medical
attention can be received.
●Always wash your hands after
handling the battery support,
terminals, and other bat-
tery-related parts.
●Do not allow children near the
battery.
