traffic.
■When the battery is removed or
discharged
●Information stored in the ECU is
cleared. When the battery is
depleted, have the vehicle
inspected at your Toyota dealer.
●Some systems may require initial-
ization. ( P.527)
■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 terminals, contact
your Toyota dealer.
■Charging the battery
The electricity stored in the battery
will discharge gradually 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.)
■After jump starting the vehicle
(Vehicles with Stop & Start sys-
tem)
Be sure to disable the Stop & Start
system so that the battery can be
charged. ( P.265)
■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 w ill start normally
after the second a ttempt. 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 battery was dis-
charged. Before disconnecting the
battery, turn the engine switch off.
If you are unsure what mode the
engine switch was 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.126)
●Vehicles with Stop & Start system:
For a while after the battery termi-
nals have been disconnected and
reconnected, for a while after the
battery has been replaced, the
Stop & Start system may not auto-
matically stop the engine for
approximately 5 to 60 minutes.
■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 performance 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 performance 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-
