COROLLA H/B_U
recharge the battery of your
vehicle.
5 Open and close any of the
doors of your vehicle with the
engine switch OFF.
6 Maintain the engine speed of
the second vehicle and start
the engine of your vehicle by
turning the engine switch to
ON.
7 Once the vehicle’s engine
has started, remove the
jumper cables in the exact
reverse order from which
they were connected.
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
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 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.539)
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
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 replacing the battery
Use a battery that conforms to
European regulations.
Use a battery that the case size is
same as the previous one (LN2),
20 hour rate capacity (20HR) is
