WARNING
The risk of skidding and having an accident increases due to
malfunctioning driving safety systems.
The brake system functions normally, but without the systems
listed. The wheels could therefore lock if you brake hard,
for example.
This will greatly impair the ability to steer and brake. The
braking distance may increase in emergency braking situa-
tions.

Pull over and stop the vehicle, paying attention to road and
traffic conditions.
