SYSTEM

• Turn signal lamp is operation.

• Selector lever is not in the P position.

POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION

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 Intelligent Key backside

is contacted to push-button ignition switch, it is equivalent to the operations below.

• When starting the engine, the BCM monitors under the engine start conditions,

CVT models

- Brake pedal operating condition

- Selector lever position

- Vehicle speed

M/T models

- Clutch pedal operating condition

- Vehicle speed

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

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

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.

REAR WIPER MOTOR PROTECTION

BCM detects the rear wiper stopping position according to the rear wiper stop position signal.

When the rear wiper stop position signal does not change for more than 5 seconds while driving the rear

wiper, BCM stops power supply to protect the rear wiper motor.

Condition of cancellation

1. More than 1 minute is passed after the rear wiper stop.

2. Turn rear wiper switch OFF.

3. Operate the rear wiper switch or rear washer switch.

FAIL-SAFE CONTROL OF COMBINATION SWITCH READING FUNCTION CAUSED BY LOW
POWER SUPPLY VOLTAGE

If voltage of battery power supply lower, BCM maintains combination switch reading to the status when input

voltage is less than approximately 9 V.

NOTE:

When voltage of battery power supply is approximately 9 V or more, combination switch reading function

returns to normal operation.

NOTE:
*: Power position shifts to “LOCK” from “OFF”, when ignition switch is in the OFF position, selector lever is in the P position (A/T models
and CVT models), and any of the following conditions are met.
• Closing door
• Opening door
• Door is locked using door request switch
• Door is locked using Intelligent Key
