DESCRIPTION

By associating Keyless operation key and automatic drive positioner system, the unlock operation of Keyless operation key or driver side door request switch performs memory function and entry/exit assist function.
Registration of Keyless operation key interlock function can register a different key ID to the driver seat control unit, one by one, for memory switch 1 and 2. A total of 2 key IDs can be registered.
When electric motor switch is OFF, and door unlock operation is performed using Keyless operation key or driver side door request switch, driver seat automatically adjusts to a driving position other than seat sliding. Seat sliding perform return operation and are set to standby status.
In standby status, when electric motor switch is operated from OFF to ON, return operation sets seat sliding to a registered position.

When electric motor switch signal turns ON during return operation, the operation is interrupted, electric motor switch signal turns from ON to OFF, and operation restarts.
