The braking action of PRE-SAFE
®
Brake is
ended automatically if:
R you manoeuvre to avoid the obstacle
R there is no longer any danger of a collision
R there is no longer an obstacle detected in
front of your vehicle
If you approach an obstacle and PRE-SAFE ®
Brake detects a risk of a collision, the system
will alert you both visually and acoustically. If you do not brake or take evasive action, the
system will warn you by automatically braking
the vehicle gently. If there is an increased risk
of collision, preventive passenger protection
measures (PRE-SAFE ®
) are activated
(Y page 54). If a risk of collision remains at
speeds over 30 km/h and you do not brake,
take evasive action or significantly acceler-
ate, automatic braking may be performed up
to a level of automatic emergency braking.
Automatic emergency braking is not per-
formed until immediately prior to an accident
that can no longer be avoided. Anti-theft systems

WARNING
If the windscreen wipers begin to move while
you are changing the wiper blades, you can be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windscreen wipers and
ignition before changing the wiper blades.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
! Never open the bonnet/tailgate if a wiper
arm is folded away from the windscreen/
rear window. Never fold a windscreen wiper arm without
a wiper blade back onto the windscreen/
rear window.
Hold the windscreen wiper arm firmly when
you change the wiper blade. If you release
the wiper arm without a wiper blade and it
falls onto the windscreen/rear window, the windscreen/rear window may be damaged
by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.
