PRE-SAFE®(anticipatory occupant
protection system)
Introduction
In certain hazardous situations, PRE-SAFE®
takes pre-emptive measures to protect the
vehicle occupants.
Important safety notes
!Make sure that there are no objects in the
footwell or behind the seats. There is a dan-
ger that the seats and/or objects could be
damaged when PRE-SAFE
®is activated.
Although your vehicle is equipped with PRE-
SAFE
®, the possibility of injury in the event of
an accident cannot be ruled out. Always
adapt your driving style to suit the prevailing
road and weather conditions and maintain a
safe distance from the vehicle in front. Drive
carefully.
Function
PRE-SAFE®intervenes:
Rin emergency braking situations, e.g. when
BAS is activated
Rin critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely
Ron vehicles with the Driving Assistance
package: if BAS PLUS intervenes power-
fully or the radar sensor system detects an
imminent danger of collision in certain sit-
uations PRE-SAFE
®takes the following measures
depending on the hazardous situation detec-
ted:
Rthe front seat belts are pre-tensioned.
Rif the vehicle skids, the sliding sunroof and
the side windows are closed so that only a
small gap remains. The panorama roof with
power tilt/sliding panel is completely
closed.
Rvehicles with the memory function: the
front-passenger seat is adjusted if it is in an
unfavorable position.
Rvehicles with a multicontour seat: the air
pressure in the side bolsters of the seat
backrest is increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE
®slackens
the belt pre-tensioning. On vehicles with mul-
ticontour seats, the air pressure in the side
bolsters is reduced again. All settings made
by PRE-SAFE
®can then be reversed.
If the seat belt pre-tensioning is not reduced:
XMove the seat backrest or seat back
slightly when the vehicle is stationary.
The seat belt pre-tensioning is reduced and the locking mechanism is released.
The seat-belt adjustment is an integral part of
the PR

E-SAFE®convenience function. You
will find information on the convenience func-
tion under "Belt adjustment" (
Ypage 49).
Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on
the type and severity of the impact:
Rthe hazard warning lamps are activated
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rvehicles with a memory function: the elec-
trically adjustable steering wheel is raised

Problems with the side windows
GWARNING
If you close a side window again immediately after it has been blocked or reset, the side window
closes with increased or maximum force. The reversing feature is then not active. Parts of the

even fatal injury.
Make sure that no parts of the body are in the closing area. To stop the closing process, release
the switch or push the switch again to reopen the side window.

Sliding sunroof
Important safety notes
Your vehicle may be equipped with a sliding
sunroof or a panorama roof with power tilt/
sliding panel. In this section, the term "sliding
sunroof" refers to both types of sliding sun-
roof.
GWARNING
While opening and closing the sliding sunroof, body parts in close proximity could become
trapped. There is a risk of injury.
Make sure that no body parts are in close
proximity during the opening and closing pro-
cedures.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rduring automatic operation, push the
switch briefly in any direction
The opening or closing procedure will be stop-
ped.
GWARNING
If children operate the sliding sunroof they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
102Sliding sunroof
Opening and closing

!Only open the sliding sunroof if it is free of
snow and ice. Otherwise, malfunctions may
occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could
be damaged.
!The weather can change abruptly. It could
start to rain or snow. Make sure that the
sliding sunroof is closed when you leave the
vehicle. The vehicle electronics can be
damaged if water enters the vehicle inte-
rior.
iResonance noises can occur in addition to
the usual airflow noises when the sliding
sunroof is open. They are caused by minor
pressure fluctuations in the vehicle interior.
Change the position of the sliding sunroof
or open a side window. The noise will be
reduced or eliminated.
Sliding sunroof reversing feature
The sliding sunroof is equipped with an auto-
matic reversing feature. If a solid object
blocks or restricts the sliding sunroof during
the closing process, the sliding sunroof opens
again automatically. However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility of paying
attention when closing the sliding sunroof.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rover the last 1/6 in (4 mm) of the closing
movement
Rduring resetting
Rwhen closing the sliding sunroof again man- ually immediately after automatic reversing
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure.
If somebody becomes trapped:
Rrelease the switch immediately, or
Rpress the switch in any direction during the
