The red brake system warning lamp is lit while the engine is running.*Possible causes:
= The brake force boosting is malfunctioning and the braking characteristics may be affected.
= There is insufficient brake fluid in the brake fluid reservoir.Note the messages on the multifunction display.&WARNING Risk of accident and injury if brake force boosting is malfunctioning
If brake force boosting is malfunctioning, increased brake pedal force may be necessary for braking. The braking
characteristics may be impaired. The braking distance can increase in emergency braking situations.
Stop in a safe location immediately. Do not continue driving.Consult a qualified specialist workshop.&WARNING Risk of an accident due to low brake fluid level
If the brake fluid level is too low, the braking effect and the braking characteristics may be impaired.
