PRIUS c_U (OM52J11U)
Use the mechanical key (→P.
121) in order to perform the fol-
lowing operations (driver’s door
only):
Unlocks the doors
Locks all the doors
Turning the key rearward unlocks
the driver’s door. Turning the key
once again within 5 seconds
unlocks the other doors.
Ensure that the shift lever is in P and depress the brake pedal.
Touch the Toyota emblem side
of the electronic key to the
“POWER” switch.
When the electronic key is
detected, a buzzer sounds and the
“POWER” switch will turn to ON
mode.
When the smart key system is
deactivated in customization set-
ting, the power switch will turn to
ACCESSORY mode.
If the electronic key do es not operate prop-
erly (vehicles with a smart key system)
If communication between the electronic key and vehicle is
interrupted (→P. 142) or the electronic key cannot be used
because the battery is depleted, the smart key system and wire-
less remote control cannot be used. In such cases, the doors
can be opened and the hybrid system can be started by follow-
ing the procedure below.

When trouble arises

Firmly depress the brake pedal and check that is displayed
on the multi-information display.
Press the “POWER” switch.
In the event that the “P OWER” switch still cannot be operated, contact
your Toyota dealer.
■ Stopping the hybrid system
Shift the shift lever to P and press the “POWER” switch as you normally do
when stopping the hybrid 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. 448)
■ Changing “POWER” switch modes
Release the brake pedal and press the “POWER” switch in above.
The hybrid system does not start and modes will be changed each time the
switch is pressed. ( →P. 189)
■ If the doors cannot be locked or unlocked by the smart key system
Lock and unlock the doors by the mechanical key or wireless remote contr\
ol.
■ When the electronic key does not work properly
●Make sure that the smart key system has not been deactivated in the cus-
tomization setting. If it is off, turn the function on.
(Customizable features →P. 556)
● Check if battery-saving mode is set. If it is set, cancel the function.

■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid 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.
■ Precautions when the 12-volt battery is discharged (vehicles with a
smart key system)
●In some cases, it may not be possible to unlock the doors using the smart
key system immediately after the 12-volt battery has been disconnected and
reconnected. Use the wireless remote control or the mechanical key to lock
or unlock the doors.
● The hybrid 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
malfunction.
● The “POWER” switch mode is memorized by the vehicle. When the 12-volt
battery 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 the “POWER” switch was in ACCESSORY or ON mode before the 12-volt
battery was discharged, the audio system and/or air conditioning system
may operate when the 12-volt battery is reconnected.
■ 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 hybrid system may be unable to start. (The
12-volt battery recharges automatically while the hybrid system is operating.)
