Precaution for Idle Start/Stop System
PRECAUTIONS FOR IDLE START/STOP SYSTEM OPERATION
The operation of the idle start/stop system needs to satisfy various conditions. For details of the conditions, refer to System Description . The idle start/stop system may not operate under the conditions listed below:
- After restarting the engine, the vehicle is repeatedly stopped and started at a low speed due to traffic congestion.
- When driving the vehicle repeatedly back and forth at a low speed due to parallel parking.
- When the intelligent key is not authenticated. (In this case, the KEY warning lamp built in the combination meter blinks.)
- The battery is deteriorated. (High discharge rate.)
- A battery other than the idle start/stop system-specific battery is used.
- Ambient temperature is extremely low.
HANDLING PRECAUTIONS
To use the idle start/stop system, the vehicle needs to recognize the status of battery. For this reason, the idle start/stop system may not be activated immediately after battery change.
