- PDS (POWER DISTRIBUTION SYSTEM) is the system that BCM controls with the operation of the push-button ignition switch and performs the power distribution to each power circuit. This system is used instead of the mechanical power supply changing mechanism with the operation of the conventional key cylinder.
- The push-button ignition switch can be operated when Intelligent Key is in the following condition. Refer to Engine Start Function for details.

- Intelligent Key is in the detection area of the inside key antenna
- Insert Intelligent Key into the key slot

- Insert key fob into the key slot

- The push-button ignition switch operation is input to BCM as a signal. BCM changes the power supply position according to the status and operates the following relays to supply power to each power circuit.

- Ignition relay (built into IPDM E/R)
- Ignition relay (inserted into fuse block)
- ACC relay
- Blower relay
  NOTE：
  The engine switch operation changes due to the conditions of brake pedal, shift lever position and vehicle speed.

- The power supply position can be confirmed with the illuminating of the indicators around the push-button ignition switch.

BATTERY SAVER SYSTEM
When all of the following conditions are met for 60 minutes, the battery saver system will cut off the power supply to prevent battery discharge.

- The ignition switch is in the ACC position
- All doors are closed
- Shift lever is in the P position

Reset Condition of Battery Saver System
In order to prevent the battery from discharging, the battery saver system will cut off the power supply when all doors are closed, the shift lever is in the P position and the ignition switch is left in the ACC position for 60 minutes. If any of the following conditions are met the battery saver system is released and the steering will change automatically to the LOCK position from the OFF position.

- Opening any door
- Operating with door key cylinder on door lock
- Operating with request switch on door lock
- Operating with Intelligent Key on door lock

Press push-button ignition switch and ignition switch will change to the ACC position from the OFF position.
STEERING LOCK OPERATION
Steering is locked by steering lock unit when ignition switch is in the OFF position, shift lever shift is in the P position and any of the following conditions are met.

- Opening door
- Closing door
- Door is locked with request switch
- Door is locked with Intelligent Key

POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERATION
The power supply position changing operation can be performed with the following operations.
NOTE：

- When an Intelligent Key is within the detection area of inside key antenna and when it is inserted to the key slot, it is equivalent to the operations below.
- When starting the engine, the BCM monitors under the engine start conditions,

- Brake pedal operating condition
- Shift lever position
- Vehicle speed

Vehicle speed: less than 4 km/h (2.5 MPH)

Power supply position | Engine start/stop condition | Push-button ignition switch operation frequency
Shift lever position | Brake pedal operation condition
LOCK → ACC | — | Not depressed | 1
LOCK → ACC → ON | — | Not depressed | 2
LOCK → ACC → ON → OFF | — | Not depressed | 3
LOCK → START ACC → START ON → START | P or N position | Depressed | 1
Engine is running → OFF | — | — | 1

Vehicle speed: 4 km/h (2.5 MPH) or more

Power supply position | Engine start/stop condition | Push-button ignition switch operation frequency
Shift lever position | Brake pedal operation condition
Engine is running → ACC | — | — | Emergency stop operation
Engine stall return operation while driving | N position | Not depressed | 1
Emergency stop operation

- Press and hold the push-button ignition switch for 2 seconds or more.
- Press the push-button ignition switch 3 times or more within 1.5 seconds.
