When the active cruise control is automatically paused, it can only be reactivated when safe conditions are restored. The message "Activation
not possible, conditions unsuitable" is displayed while reactivation is not possible.
When the conditions allow, it is recommended that the function be reactivated by pressing button 2 (SET+) or 3 (SET-), which will make the
current speed of your vehicle the new cruise speed setting, rather than by pressing button 4 (on/pause) which reactivates the cruise control
using the old cruise speed setting, which may be very different from the current speed of your vehicle.
