Sounds like Winter Mode is engaged, in the manual its called rain/snow/ice mode, maybe page 74, once it's turned on it stays on till turned off.
its the forward position of the dynamic mode switch
RAIN/ICE/SNOW MODE
Rain/Ice/Snow mode optimises
stability of the vehicle to suit low grip
conditions. This helps the vehicle to
perform in a more gentle and
controlled manner, to avoid skidding, allowing
more confident progress under adverse
conditions.
Note: Rain/Ice/Snow mode cannot be active at
the same time as Dynamic mode.
Note: Rain/Ice/Snow mode will remain
selected indefinitely, even after the ignition is
switched off. Rain/Ice/Snow mode must be
deselected if no longer required.
