The warning light on the dial turns on (on certain versions together with the message on the display) when one or more doors, the boot (indication fitted on some versions only) or the bonnet are not properly shut.
Symbols 
shown on the multifunction
display indicate incomplete left/right door closing.
With doors and boot open, if 4 km/h speed is exceeded the buzzer will sound (only for versions with reconfigurable multifunction display).
IMPORTANT On versions not fitted with electric door lock, no warning message will be displayed if door is not perfectly closed or is left open.
