and PRE-SAFE ®
Brak edetects arisk of acol-

visually and acoustically. If you do not brake

risk of acollision, PRE-SAFE ®
is activated
(Y page 40). If the risk of collision persist sand

application may be carried out. G
Risk of accident
Only clearly detected obstacles will trigger a

In particular, the detection of obstacles can
be impaired if ther eis:
R dirt on the sensors or the sensors are cov-

R snow or heavy rain
R interferenc ebyother radar sources
R the possibility of strong radar reflections,

Depending on the curren tspeed, PRE-SAFE ®

The active light function is
asystem that
moves the headlamps accordin gtothe steer-

be activated when the dipped-beam head-
lamps are switched on.
