Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the 12-volt battery of your vehicle.

Open and close any of the doors of your vehicle with the power
switch off.

Maintain the engine speed of the second vehicle and start the EV
system of your vehicle by turning the power switch to ON mode.

Make sure the “READY” indicator comes on. If the indicator does
not come on, contact your Scion dealer.

Once the EV system has started, remove the jumper cables in the
exact reverse order from which they were connected.

Once the EV system starts, have the vehicle inspected at your Scion
dealer as soon as possible.

■

Starting the EV system when the 12-volt battery is discharged 

The EV system cannot be started by push-starting.

■

To prevent 12-volt battery discharge

●

Turn off the headlights and the air conditioning system while the EV system
is off.

●

Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.

■

Charging the 12-volt battery

The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of
certain electrical appliances. If the vehicle is left for a long time, the 12-volt
battery may discharge, and the EV system may be unable to start. (The 12-
volt battery recharges automatically while the EV system is operating.)

When recharging or replacing the 12-volt battery

●

In some cases, it may not be possible to unlock the doors using the smart
key system when the 12-volt battery is discharged. Use the wireless remote
control or the mechanical key to lock or unlock the doors.

●

The EV system may not start on the first attempt after the 12-volt battery has
recharged but will start normally after the second attempt. This is not a mal-
function.

●

The power switch mode is memorized by the vehicle. When the 12-volt bat-
tery is reconnected, the system will return to the mode it was in before the
12-volt battery was discharged. Before disconnecting the 12-volt battery,
turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt bat-
tery discharged, be especially careful when reconnecting the 12-volt battery.

CAUTION

■

Avoiding 12-volt battery fires or explosions

Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the 12-volt battery:

●

Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.

●

Do not allow the other end of the jumper cable connected to the “+” termi-
nal 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 12-volt battery.
