8-2. Steps to take in an emergency
8
When trouble arises
Once the engine starts, have the
vehicle inspected at your Toyota
dealer as soon as possible.
■ 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
stopped.
(Vehicles with Stop & Start system:
Except when the engine is stopped
due to the Stop & Start system)
● 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 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.699)
■ 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.)
■ When recharging or replacing
the battery (vehicles without
smart key start system)
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.
■ When recharging or replacing
the battery (vehicles with smart
key system)
● 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 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.
■ When the battery is removed or
discharged (vehicles with Stop
& Start system)
The Stop & Start system may not
automatically stop the engine for up
to an hour.
■ When replacing the battery
● Vehicles with Stop & Start system:
Use a genuine battery specifically
designed for use with the Stop &
Start system or a battery with equiv-
alent specifications to a genuine
battery. If an unsupported battery is
used, Stop & Start system functions
may be restricted to protect the bat-
