Unlocking the trunk (Sedan)
The trunk lid swings upwards when opened. Therefore, make sure that there is sufficient clearance above the trunk lid.
If the trunk cannot be unlocked with the SmartKey or KEYLESS-GO, use the mechanical key.
If you use the mechanical key to unlock and open the trunk lid, the anti-theft alarm system will be triggered.
