they provide an indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with-
out an air bag being deployed. This is the case if
only parts which are relatively easily deformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed eventhough the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as a result.
If the restraint system control unit detects a side
impact or that the vehicle is rolling over, the rel-
evant restraint system components are activa-
ted independently of one another depending on
the apparent type of accident. If the system
determines a need for additional protection for
the vehicle occupants, the Emergency Tension-
ing Devices are triggered.
RSide impact air bag on the side of impact,
independently of the Emergency Tensioning
Device and the use of the seat belt on the
driver's seat
The side impact air bag on the front-
passenger side deploys under the following
conditions:
-the OCS system detects that the front-
passenger seat is occupied or
-the belt tongue is engaged in the belt
buckle of the front-passenger seat
iNot all air bags are deployed in an accident.
The different air bag systems work independ-
ently of each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration and the apparent type of accident:
RFrontal collision
RSide impact
RRollover
PRE-SAFE®(anticipatory occupant
protection system)
Introduction
In certain hazardous situations, PRE-SAFE®
takes pre-emptive measures to protect the vehi-
cle occupants.
Important safety notes
!Make sure that there are no objects in the
footwell under or behind the seats when mov-
ing the seats back. There is a risk that the
seats and/or the objects could be damaged.
Despite your vehicle being equipped with the
PRE-SAFE
®system, the possibility of personal
injuries occurring as a result of an accident can-
not be eliminated. 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 physi-
cal limits are exceeded and the vehicle under-
steers or oversteers severely
Ron vehicles with DISTRONIC PLUS: if adaptive
Brake Assist intervenes powerfully
PRE-SAFE
®takes the following measures
depending on the hazardous situation detected:
Rthe seat belts are pre-tensioned.
Rif the vehicle skids, the side windows are
closed.
Rvehicles with the memory function for the
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavorable posi-
tion.
If the hazardous situation passes without result-
ing in an accident, PRE-SAFE
®slackens the belt
pre-tensioning. 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 PRE-SAFE
®convenience function. Informa-
tion about the convenience function can be
found under "Belt adjustment" (
Ypage 39).

Correct driver's seat position
GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
Observe the following when adjusting steering
wheel :, seat belt ;and driver's seat =:
Ryou are as far away from the driver's air bag as
possible.
Ryou are sitting in a normal upright position.
Ryour thighs are slightly supported by the seat
cushion.
Ryour legs are not entirely stretched and you
can depress the pedals properly.
Rthe back of your head is supported at eye level
by the center of the head restraint.
Ryou can hold the steering wheel with your
arms slightly bent.
Ryou can move your legs freely.
Ryou can see all the displays in the instrument
cluster clearly.
Ryou should have a good overview of traffic
conditions.
Rthe seat belt is pulled snugly against the bodyand is routed across the center of your shoul-
der and across your hips in the pelvic area.

Important safety notes
GWARNING
Children could become trapped if they adjust
the seats, particularly when unattended.
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.
The seats can still be adjusted when there is no
SmartKey in the ignition lock.
GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.
Observe the safety notes on "Air bags"
(
Ypage 40) and "Children in the Vehicle"
(Ypage 49).

Press one of the memory function position but-
tons. The adjustment process is stopped. This
function is only available on vehicles with mem-
ory function.
GWARNING
If children activate the EASY-ENTRY/EXIT fea-
ture, they can become trapped, particularly
when unattended. 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.
GWARNING
If you drive off while the EASY-ENTRY/EXIT
feature is making adjustments, you could lose
control of the vehicle. There is a risk of an
accident.
Always wait until the adjustment process is
complete before driving off.
The EASY-ENTRY/EXIT feature makes getting in
and out of your vehicle easier.
You can activate and deactivate the EASY-
ENTRY/EXIT feature using the multimedia sys-
tem (see the separate operating instructions for
the multimedia system).
Position of the steering wheel when the
EASY-ENTRY/EXIT feature is active
The steering wheel swings upwards when you:
Rremove the SmartKey from the ignition lock
Ropen the driver's door and the Stop button is
in position 1
iThe steering wheel only moves upwards if it
has not already reached the upper stop.
Position of the steering wheel for driv-
ing
The steering wheel is moved to the last selected
position when you:
Rclose the driver's door and
Rpress the Start/Stop button once
When you close the driver's door with the igni-
tion switched on, the steering wheel is also
automatically moved to the previously set posi-
tion. The last position of the steering wheel column is
stored after each manual setting or when you
store the setting with the memory function
(
Ypage 84).
Crash-responsive EASY-EXIT feature
If the crash-responsive EASY-EXIT feature is trig-
gered in an accident, the steering column will
move upwards when the driver's door is opened
or the SmartKey is removed from the ignition
lock. This makes it easier to exit the vehicle and
rescue the occupants.
Mirrors
Exterior mirrors
Important safety notes
GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.
