AdjustingVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Sitting safely
The ideal seating position meeting the needs of
the occupants can make a vital contribution to
relaxed, fatigue-free driving.
The seating position plays an important role in
an accident in combination with:
▷Safety belts, refer to page 53.▷Head restraints, refer to page 54.▷Airbags, refer to page 101.
Seats
Information
WARNING
Seat adjustments while driving can lead
to unexpected movements of the seat. Vehicle
control could be lost. There is risk of an acci‐
dent. Only adjust the side on the driver's side
when the vehicle is stationary.◀
WARNING
With a backrest inclined too far to the
rear, the protective effect of the safety belt
cannot be ensured anymore. There is a danger
of sliding under the safety belt in an accident.
There is risk of injuries or danger to life. Adjust
the seat prior to starting the trip. Adjust the
backrest in an as upright position as possible
and do not adjust again while driving.◀
WARNING
There is risk of jamming when moving the
seats. There is risk of injuries or risk of property
damage. Make sure that the area of movement
of the seat is clear prior to any adjustment.◀

WARNING
The stability of the child restraint system
is limited or compromised with incorrect seat
adjustment or improper installation of the child
seat. There is risk of injuries or danger to life.
Make sure that the child restraint system fits
securely against the backrest. If possible, adjust
the backrest tilt for all affected backrests and
correctly adjust the seats. Make sure that seats
and backrests are securely engaged. If possible,
adjust the height of the head restraints or re‐
move them.◀
Installing child re‐
straint systems
Information
Pay attention to the specifications of the child
restraint system manufacturer when selecting,
installing, and using child restraint systems.
WARNING
The stability of the child restraint system
is limited or compromised with incorrect seat
adjustment or improper installation of the child
seat. There is risk of injuries or danger to life.
Make sure that the child restraint system fits
securely against the backrest. If possible, adjust
the backrest tilt for all affected backrests and
correctly adjust the seats. Make sure that seats
and backrests are securely engaged. If possible,
adjust the height of the head restraints or re‐
move them.◀
In order to faciliate the installation of a back-
facing child restraint system in the rear:
Move the front passenger's seat as far up as
possible before folding down the backrest.
On the front passenger seat
Deactivating airbags
WARNING
Active front-seat passenger airbags can
injure a child in a child restraint system when
the airbags are activated. There is risk of inju‐
ries. Make sure that the front-seat passenger
airbags are deactivated and that the PASSEN‐
GER AIRBAG OFF indicator lamp lights up.◀
After installing a child restraint system in the
front passenger seat, make sure that the front,
knee and side airbags on the front passenger
side are deactivated.
Deactivate the front-seat passenger airbags au‐
tomatically, refer to page 103.
Seat position and height
Before installing a child restraint system, move
the front passenger seat as far back as possible
and adjust its height to the highest and thus
best possible position for the belt and to offer
optimal protection in the event of an accident.
If the upper anchorage of the safety belt is lo‐
cated in front of the belt guide of the child seat,
move the passenger seat carefully forward until
the best possible belt guide position is reached.
Child seat security
The rear safety belts and the front passenger
safety belt can be permanently locked to fasten
child restraint systems.

The lamp indicates whether the airbags are ei‐
ther activated or deactivated.
▷The indicator lamp lights up
when a child is properly
seated in a child restraint fix‐
ing system or when the seat
is empty. The airbags on the
front passenger side are not
activated.
▷The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient size is detected on the seat. The
airbags on the front passenger side are ac‐
tivated.
Detected child seats
The system generally detects children seated in
a child seat, particularly in child seats required
by NHTSA when the vehicle was manufactured.
After installing a child seat, make sure that the
indicator lamp for the front-seat passenger air‐
bags lights up. This indicates that the child seat
has been detected and the front-seat passen‐
ger airbags are not activated.
Strength of the driver's and front-seat
passenger airbag
The explosive power that activates driver's/
front passenger's airbags very much depends
on the positions of the driver's/front passeng‐
er's seat.
To maintain the accuracy of this function over
the long-term, calibrate the front seats as soon
as a relevant Check Control message is dis‐
played. A message also appears on the Control
Display.
Calibrating the front seats
WARNING
There is risk of jamming when moving the
seats. There is risk of injuries or risk of property
damage. Make sure that the area of movement
of the seat is clear prior to any adjustment.◀
An appropriate Check Control message is dis‐
played.
1.Move the respective seat all the way for‐
ward.
2.Move the respective seat forward again. It
moves forward briefly.
3.Readjust the seat to the desired position.
The calibration procedure is completed when
the Check Control message disappears.
If the message continues to be displayed, re‐
peat the calibration.
If the message does not disappear after a re‐
peat calibration, have the system checked as
soon as possible.
Tire Pressure Monitor
TPM
The concept
The system monitors tire inflation pressure in
the four mounted tires. The system warns you if
there is a significant loss of pressure in one or
more tires. For this purpose, sensors in the tire
valves measure the tire inflation pressure.
Information
With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 182.
Functional requirements
The system must have been reset with the cor‐
rect tire inflation pressure; otherwise, reliable
signaling of tire pressure loss is not assured.
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to en‐
sure that the system will operate properly.

Enlarging the trunk
The concept
The trunk can be enlarged by folding down the
rear seat backrest.
Without through-loading system: The rear
backrest is divided 60–40. The backrest of the
left seat is connected to the backrest center
section.
With through-loading system: the rear seat
backrest is divided into three parts at a
40/20/40 ratio.
The sides can be folded down separately or to‐
gether.
Information
WARNING
Danger of jamming with folding down the
backrests. There is risk of injuries or risk of
property damage. Make sure that the area of
movement of the rear backrest is clear prior to
folding down.◀
WARNING
The stability of the child restraint system
is limited or compromised with incorrect seat
adjustment or improper installation of the child
seat. There is risk of injuries or danger to life.
Make sure that the child restraint system fits
securely against the backrest. If possible, adjust
the backrest tilt for all affected backrests and
correctly adjust the seats. Make sure that seats
and backrests are securely engaged. If possible,
adjust the height of the head restraints or re‐
move them.◀
WARNING
With an unlocked backrest, an unsecured
load can be thrown into the car's interior, for
example in case of an accident, braking or eva‐
sive maneuver. There is risk of injuries. Make
sure that the backrest engages into the locking
after folding it back.◀
WARNING
With a rear backrest that is not locked,
the protective function of the middle safety belt
is not guaranteed. There is risk of injuries or
danger to life. If you are using the middle safety
belt, lock the wider rear backrest.◀
WARNING
Body parts can be jammed when moving
the head restraint. There is risk of injuries.
Make sure that the area of movement is clear
when moving the head restraint.◀
Folding down rear seat backrests
The rear seat backrest can be folded down
from the front or from the trunk.
The right backrest can be folded down sepa‐
rately. The left backrest can be folded down in
combination with the middle section. Fold in
the middle head restraint.
Reach into the recess and fold forward.
