Front active head restraints
In a rear collision of a sufficient strength, the
active head restraint reduces the distance to
the head.
Do not use seat or head restraint covers
that could impair the function of the active
head restraint. Otherwise, the protective func-
tion of the active head restraint will not be
ensured and its full potential in reducing the risk
of injury in the event of a rear collision may not
be realized.
In the event of malfunctions, deactivation or
triggering of the active head restraints, have the
testing, repair and removal executed only by a
BMW center or a workshop that works accord-
ing to repair procedures of BMW with corre-
spondingly trained personnel and that has the
required explosives licenses. Unprofessional
attempts to work on the system could lead to
failure in an emergency or to undesired airbag
activation, either of which could result in per-
sonal injury.<
For technical reasons, the head restraint
cannot be removed.<

>To lower: press the button, arrow1, and
slide the head restraint down.

sengers will be sitting in the rear. Reinstall
head restraints before transporting passengers
in the rear.<

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle; otherwise, they could endanger
themselves and/or other persons by opening
the doors, for example.<
The rear center seat is not suitable for installing
child restraint systems for all age groups,
approved for the age group in question.
Children always in the rear
Accident research has shown that the safest
place for children is on the rear seat.
Children under the age of 13 or smaller
than 5 ft/150 cm may be transported only
in the rear in suitable child restraint systems
appropriate for their age, weight and size. Oth-
erwise, there is an increased risk of injury in the
event of an accident.<
Children 13 years of age or older must be buck-
led in with a safety belt as soon as there no
longer is any child restraint system that is
appropriate for their age, size and weight.
Children in the front passenger seat
Should it be necessary to use a child
restraint system on the front passenger
seat, the front and side airbags for the front pas-
senger must be deactivated. Otherwise, a child
traveling on that seat will face a significant risk
of injury if the airbags are triggered off, even
with a child restraint system.<
For more information on automatic deactivation
of the front passenger airbags refer to page95.
Installing child restraint
systems
Observe the child restraint system manu-
facturer's instructions when selecting,
installing and using child restraint systems.
Otherwise, the protective effect may be dimin-
ished. <
Standard child restraint systems are designed
to be secured with a lap belt or with the lap-belt
section of a lap-and-shoulder belt. Incorrectly
or improperly installed child restraint systems
can increase the risk of injury to children.
Always follow the installation instructions for
the system with the greatest care.
On the front passenger seat
After installing a child restraint system on
the front passenger seat, make sure that
the front and side airbags for the front passen-
ger are deactivated; otherwise, there is an
increased risk of injury if the airbags deploy.<
Seat position
Before installing a child restraint system, move
the front passenger seat as far back and up as
possible to obtain the best possible position for
the belt. Do not change the seat position after
this.
Backrest width*
The backrest width of the front passenger
seat must be at its widest possible set-
ting. Do not change the setting after installing
the child seat. Otherwise, the child seat's stabil-
ity on the front passenger seat is limited.<
1.Adjust the backrest width to its widest
setting, refer to page44.
2.Install the child seat.

Child seat security
The rear safety belts and the front passenger
safety belt can be prevented from being pulled
out in order to fasten child restraint systems.
To lock the safety belt
1.Secure the child restraint system with the
belt.
2.Pull the belt strap all the way out.
3.Allow the belt strap to retract and pull it taut
against the child restraint system.
The safety belt is locked.
To unlock the safety belt
1.Open the belt buckle.
2.Remove the child restraint system.
3.Allow the safety belt strap to retract all the
way.
LATCH child restraint fixing
system
LATCH: Lower Anchors and Tethers for CHil-
dren.
To install and use the LATCH child
restraint system, follow the operating and
safety instructions provided by the manufac-
turer of the system; otherwise, the protective
function of the seat may be compromised.<
Before installing the child seat, pull the belt out
of the area for the child restraint fixing system.Ensure that both lower LATCH anchors
are correctly engaged and that the child
restraint system is resting firmly against the
backrest; otherwise, the protective function of
the seat may be compromised.<
Rear seats with through-loading
system
The anchor points for the lower LATCH
anchors are located behind the labeled protec-
tive caps.
Rear seats without through-loading
system
The anchor points for the lower LATCH
anchors are located at the positions indicated
by arrows, in the gap between the seat and the
backrest.

Child restraint system with tether strap
Use the top tether anchors to secure child
restraint systems only; otherwise, the
anchors could be damaged.<
Sedan
There are three additional anchors for child
restraint systems with tether straps, see
arrows.
Sports Wagon
There are three additional anchors under a
cover for child restraint systems with tether
straps, see arrows.
Placement of the tether strap
Make sure the upper retaining strap does
not run over sharp edges and is not
twisted as it passes to the top anchor. Other-
wise, the strap will not properly secure the child
restraint system in the event of an accident.<

Sport program and manual
operation M/S
Move selector lever from position D toward the
left into the M/S shifting slot; the Sport program
is activated. This position is recommended for a
performance-oriented driving style.
DS is displayed in the instrument cluster.
To deactivate the sport program or manual
mode M/S, move the selector lever to the right
into position D.
Shifting gears via the selector lever
Move selector lever from position D toward the
left into the M/S shifting slot:
When you press the selector lever forwards or
backwards, the manual mode is activated and
Steptronic changes gear.
The engaged gear, e.g. M1 is displayed in the
instrument cluster.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system.
The gear selected is briefly displayed in the
instrument cluster, followed again by the gear
actually in use.
Shifting gears via shift paddles* on
the steering wheel
The shift paddles allow you to shift gears
quickly since both hands can remain on the
steering wheel.
>When you use the shift paddles on the
steering wheel to shift gears in automatic
mode, the transmission switches to manual
mode.
>If you do not accelerate or shift gears using
the shift paddles for a certain amount of
time, the transmission switches back to
automatic mode.
If the selector lever is in the M/S gear
plane, manual mode remains active.<
>To upshift, briefly pull the right shift
paddle +.
>To downshift, briefly pull the left shift pad-
dle –.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be executed by the system.
