Enabling and disabling steering assistance when driving
Pilot Assist steering assistance can be easily enabled or disabled using the steering wheel buttons. This allows you to control it without going into settings while driving.
Steering assistance is part of Pilot Assist and can only be used when Pilot Assist is active.
If steering assistance is unavailable for some reason, such as worn lane markings, you won't be able to activate it. However, if steering assistance is enabled, it will automatically activate when the required conditions are met.
Press the steering assistance button 
on the left side of the steering wheel.
Steering assistance is either enabled or disabled.
If steering assistance is enabled, it will activate automatically when the required conditions are met.
If disabled, Pilot Assist will remain active but mainly provide speed- and distance-keeping support.
