Seats
Note before adjusting
Never attempt to adjust your seat while
operating the vehicle. The seat could
respond with unexpected movement and the
ensuing loss of vehicle control could lead to an
accident.
On the front passenger side as well, do not tilt
the backrest too far toward the rear. Failure to
observe this precaution can prevent the belt
from providing effective protection against
injury, as the passenger could slide under the
belt in an accident.<
Also follow the instructions regarding damage
to the safety belt on page51.
Convertible: with the wind deflector fitted,
do not incline the front seat backrests too
far backward if the seat is to be moved back to
the end position. Otherwise, the wind deflector
will be damaged.<
Adjusting seat
To ensure that the safety systems con-
tinue to provide optimized protection,
please follow the adjustment instructions on
page46.<

is approx. at ear level. Otherwise, there is
increased danger of injury in the event of an
accident. Only remove the head restraints if no
one will be sitting on the seat in question. Rein-
stall the head restraints before transporting
passengers, as otherwise the head restraint
cannot provide its protective function.<

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle; otherwise, they could endanger
themselves and other persons, e.g. by opening
the doors.<
Children always in the rear
Accident research shows that the safest place
for children is in the back.
Children younger than 13 years of age or
with a height under 5 ft/150 cm may only
be transported in the rear in child restraint sys-
tems which correspond to the age, weight and
height of the child. Otherwise, there is an
increased danger of injury in an accident.<
Children 13 years of age or older must wear a
safety belt as soon as a suitable child restraint
system can no longer be used due to their age,
size and weight.
Exception for front passenger seat
Should it be necessary to use a child
restraint system on the front passenger
seat, the front, knee and side airbags on the
passenger side must be deactivated. Other-
wise, there is an increased risk of injury for the
child if the airbags are triggered, even with a
child restraint system.<
For more information on automatic deactivation
of the front passenger airbags, refer to page89.
Installing child restraint
systems
Follow child restraint system manufac-
turer's instructions for the selection,
installation and use of child restraint systems.
Otherwise, the degree of protection they offer
may be reduced.<
On front passenger seat
After mounting a child restraint system on
the front passenger seat, make sure that
the front and side airbags on the front passen-
ger side are deactivated, as otherwise there is
an increased risk of injury if the airbags are trig-
gered.<
Backrest width
Before mounting a child restraint system
on the front passenger seat, the backrest
width adjustment must be open completely.<
1.Adjust the backrest width to the fully open
position, refer to page47.
2.Install child's seat.
Child seat security
All rear safety belts and the safety belt for the
front passenger can be locked against pulling
out to secure child restraint systems.
Locking safety belt
1.Secure the child restraint system with the
belt.
2.Pull out the belt webbing completely.
3.Allow the belt webbing to be pulled in and
pull taut against the child restraint system.
The safety belt is locked.

M Engine Dynamic Control
With M Engine Dynamic Control you can influ-
ence how sporty the reaction of your vehicle to
accelerator pedal movements is to be. Three
programs are available for engine control.
"P 400" program
In the "P 400" program the engine reacts gently
to the movement of the accelerator pedal. This
is, for example, ideal for city driving or driving on
snow. In the process, the fuel consumption is
minimal and the engine output is reduced.
"P 500" program
The "P 500" program provides maximum per-
formance and more spontaneous reaction of
the engine to accelerator pedal movements.
"P 500 Sport" program
In the "P 500 Sport" program the engine reacts
especially spontaneously and uncompromis-
ingly sporty with maximum performance to
accelerator pedal movements.
Selecting program
Each time the engine is started, the "P 400"
program is activated.
Press the POWER button to activate the
"P 500" program. Pressing the POWER button
repeatedly switches between the programs
"P 400" and "P 500".
You can also activate your preferred program
with the button on the steering wheel, refer
to MDrive on page54. You can only activate the
"P 500 Sport" program with MDrive.For the programs "P 500" and "P 500 Sport"
