When trouble arises
■Stopping the EV system
Set the parking brake, shift the shift lever to P and press the power switch as
you normally do when stopping the EV system.
■ Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the
electronic key battery be replaced immediately when the battery is depleted.
(P. 299)
■ Changing power switch modes
Within 10 seconds of the buzzer sounding, release the brake pedal and press
the power switch.
The EV system does not start and modes will be changed each time the
switch is pressed.( P. 166)
■ When the electronic key does not work properly
Make sure that the smart key system has not been deactivated in the custom-
ization setting. If it is off, turn the function on.
(Customizable features: P. 414)

3888-2. Steps to take in an emergency
■When recharging or repl acing 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.
