®
system
PRE-SAFE ®
system takes pre-emptive meas-
ures to protect you in certain hazardous sit-
uations.
PRE-SAFE ®
intervenes in the event of:
R emergency braking situations, e.g. if BAS
Brake Assist intervenes
R critical situations involving driving dynam-
ics, e.g. if the vehicle oversteers or under-
steers significantly due to physical limits
being exceeded
If you are driving faster than approximately
35 km/h, PRE-SAFE ®
takes the following
measures in the aforementioned situations:
R It tensions the front seat belts.
R Vehicle with memory functions*: it adjusts
the front-passenger seat if this is in an
unfavourable position.
R If the vehicle skids, it closes the sliding/
tilting sunroof* and side windows so that
only a small gap remains. If the hazardous situation passes without
resulting in an accident, PRE-SAFE
®
releases
the belt pretensioning. You can then reverse
all settings made by PRE-SAFE ®
again.
If the seat belts are not released:
X Move the backrest or the seat back slightly
until the belt tension is reduced.
The locking mechanism releases. G
Risk of injury
Make sure when adjusting the seat that
nobody can become trapped.
! Make sure that there are no objects in the
footwell or behind the seats when adjusting
the seats. You could otherwise damage the
seats and the objects. NECK-PRO head restraint
NECK-PRO head restraints are designed to
increase protection to the driver's and front-
passenger's head and neck. To this end, the
head restraints on the driver's and front-
passenger seats are moved forwards and
upwards in the event of a rear-end collision
when viewed in the direction of travel. This
provides better head support. G
Risk of injury
Head restraint covers prevent the NECK-
PRO head restraints from triggering cor-
rectly. Consequently, the NECK-PRO head
restraints cannot provide the intended level
of protection. Do not use head restraint
covers.
If the NECK-PRO head restraints are triggered
in an accident, you must reset the head
restraints on the driver's and front-passenger
seats (Y page 310). Head restraints that have
been triggered are tilted forwards. Safety

i Make sure that the exterior mirrors are
always folded out fully while the vehicle is
in motion; otherwise, they may vibrate. Resetting the exterior mirrors If the battery has been disconnected or has
become discharged, the exterior mirrors
must be reset. If this is not done, the exterior
mirrors will not fold in when you select the
"Fold in mirrors when locking" function in the
on-board computer (Y
page 133).
X Make sure that the key is in position 1in
the ignition lock.
X Briefly press button 1.

soon as you lock the vehicle from the out-
side
R The exterior mirrors fold out again auto-
matically as soon as you unlock the vehicle

1. Automatic anti-dazzle mirrors*
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
dazzle mode if the ignition is switched on and
incident light from headlamps strikes the sen-
sor in the rear-view mirror.
The mirrors do not go into anti-dazzle mode if
reverse gear is engaged or the interior lighting
is switched on. G
Risk of accident
If incident light from headlamps cannot
strike the sensor in the rear-view mirror, for
instance if the safety net is fitted, the mir-
ror's automatic anti-dazzle function will not
work.
Incident light could then dazzle you. This
may distract you from the traffic conditions,
and you may thereby cause an accident. In
this case, adjust the rear-view mirror man-
ually. Controls
