cleared. When the battery is
depleted, have the vehicle
inspected at you r Toyota dealer.

ization. ( P.507)

minals
When the battery terminals are

the ECU is cleared . Before remov-
ing the battery terminals, contact
your Toyota dealer.
■Charging the battery
The electricity stor ed in the battery
will discharge gradu ally even when
the vehicle is not i n 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 ma y be unable to
start. (The battery recharges auto-
matically during driving.)
■After jump starting the vehicle

tem)
Be sure to disable the Stop & Start
system so that the battery can be
charged. ( P.265)
■When recharging or replacing

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 se cond 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.
●Vehicles with power back door:
The power back door must be ini-
tialized. ( P.127)
●Vehicles with Stop & Start system:
The Stop & Start system may not
automatically stop the engine for
up to an hour.
■When replacing the battery
●Use a Central Degassing type bat-
tery (European Regulations).
●Vehicles with Stop & Start system:
Use a genuine battery specifically
designed for use with the Stop &
Start system or a battery with
equivalent specifications to a gen-
uine battery. If an unsupported
battery is used, Stop & Start sys-
tem functions may be restricted to
protect the battery.
Also, battery per formance may
decrease and the engine may not
be able to restart. Contact your
Toyota dealer for details.
●Vehicles without Stop & Start sys-
tem: Use a battery that the case
size is same as the previous one
(LN3), 20 hour rate capacity
(20HR) is equivalent (70Ah) or
greater, and per formance rating
(CCA) is equivalent (603A) or
greater.
Vehicles with Stop & Start system:
Use a battery that the case size is
same as the previous one (LN3), 20
hour rate capacity (20HR) is equiva-
lent (65Ah) or greater, and perfor-
mance rating (CCA) is equivalent
(603A) or greater.
