If you wish, the tilt alarm sensor and
interior motion sensor are perma-
nently switched off. You can have this set
at your BMW Sports Activity Vehicle Cen-
ter.<
Interior motion sensor

Transporting children safely

Transporting children safely
The right place for children
Children always in the rear
Accident research shows that the safest
place for children in a vehicle is in the rear
seat.
Older children should be tightly secured
with a safety belt, after they have outgrown
a booster seat that is appropriate for their
age, height and weight.
A child sitting in the rear seat and not
properly restrained may place his or
her head on or near the airbag, if so
equipped. For example, a child Ñ even
though belted Ñ may fall asleep with his or
her head against the side airbag. It may be
difficult for a driver to ensure that children
in the rear seat will remain properly posi-
tioned at all times and do not place their
heads on or near the side airbag. There-
fore, we recommend that the rear side air-
bags, if provided, be deactivated if you plan
to transport children in the rear seat.<
Deactivation of the rear seat side
airbags
The rear seat side airbags may already
have been deactivated by a BMW Sports
Activity Vehicle Center. Labels in the rear
door opening should indicate the status of
your rear seat side airbags. If you are
uncertain of their status, or wish to have the
airbags activated or deactivated, please
contact your BMW Sports Activity Vehicle
Center.
Child-restraint system in rear
Children under 13 years of age and
children less than 5 ft/150 cm tall
should always ride in the rear and the
restraint systems should be properly
adjusted.<
Younger children should be secured in an
appropriate forward-facing child-restraint system that has first been properly secured
with a safety belt.
All rear seating positions in your vehicle
meet the recommendations of SAE J1819,
an industry-recommended practice for
securing child-restraint systems in motor
vehicles.
Exception for the front passenger
seat
Should it become necessary to use a
child-restraint system on the front
passenger seat, the airbags on the passen-
ger's side must be deactivated. The pas-
senger airbag indicator lamp above the
interior rearview mirror must light up con-
tinuously. Otherwise, the front passenger
airbags remain active and there is consid-
erable risk of injury to children if the airbags
are triggered, even with a child-restraint
system. In this case, children should be
seated in the rear and the system should be
checked at your BMW Sport Activity Vehi-
cle Center.<
Never install a rearward-facing child-
restraint system in the front passen-
ger seat of this vehicle if the passenger air-
bag is not deactivated. If you do so, the
child could be severely injured when the
airbag is triggered.
Your vehicle is equipped with an airbag
supplemental restraint system for the front
passenger. Because the backrest on any
rearward-facing child-restraint system Ð of
the kind designed for infants under 1 year
and 20 Ibs/9 kg Ð would be within the air-
bag's deployment range, you should never
mount such a system in the front passenger
seat, since the impact of the airbag against
the child restraint's backrest could lead to
serious or fatal injuries.<
More information on automatic deactiva-
tion of the front passenger airbags, refer to
page 55.

Installing child-restraint
systems
Before installing any child-restraint system
or child seat, read the following:
Observe the child-restraint system
manufacturer's instructions for instal-
lation and use. Otherwise the degree of
protection can be reduced.
After an accident, have all parts of the rele-
vant vehicle safety belt system checked by
a BMW Sports Activity Vehicle Center and
replaced if necessary.<
Commercially-available child-restraint sys-
tems are designed to be secured with a lap
belt or with the lap belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint systems
can increase the risk of injury to children.
Always read and follow the instructions that
come with the system.
Child seat security
All of the rear belt retractors and the front
passenger's safety belt can be locked for
mounting and securing child-restraint sys-
tems.
Information regarding this is located near
the buckle latch of each safety belt.
To lock the safety belt
Pull the entire length of the belt from the
belt retractor. Allow the reel to retract the
belt somewhat and engage the buckle,
then tighten the belt against the child-
restraint system. The retraction mechanism
is now locked.
To unlock the safety belt
Release the buckle, remove the child-
restraint system and allow the belt retractor
to reel the belt completely in.
Child-restraint system with tether
strap
If you use a child-restraint system with a
tether strap, three additional tether anchor-
age points have been provided, refer to the
arrows in the illustration. Depending on the
location selected for seating in the rear
passenger area, attach the tether strap to
the corresponding anchorage point to
secure the child-restraint system, as
shown in the illustration below.
Each seating position is fitted with a head
restraint.
Outer seating positions:
Lift the head restraint and pass the tether
strap between the head restraint and the
seat back. It is recommended to readjust
the head restraint into the lowest possible
position.
Center seating position:
The head restraint must be adjusted into
the lowest possible position. Pass the
tether strap over the head restraint.

To engage
The lever engages automatically.
To release
Pull up slightly on the lever, press the but-
ton and lower the lever.
If exceptional circumstances should
make it necessary to engage the
handbrake while the vehicle is in motion,
do not pull it too strongly. In doing so, con-
tinuously press the button of the handbrake
lever.
Strong application of the handbrake can
lead to overbraking of the rear axle and
associated 'fishtailing' of the vehicle rear
end.
The brake lamps do not light up when the
handbrake is applied.
Vehicles with manual transmission:
When parking on inclines, apply the hand-
brake, as even engaging the first or reverse
gear might not under certain circum-
stances secure the vehicle against moving.
Vehicles with automatic transmission:
Engage selector-lever position P.<
To prevent corrosion and one-sided
braking action, occasionally apply the
handbrake lightly when the vehicle is
slowly coming to a standstill at a traffic light
if the traffic conditions are suitable.<
Manual transmission
While shifting gear in the 5th/6th gear
level, make sure that you press the
gearshift lever to the right to prevent inad-
vertently selecting a gear in the 3rd/4th
gear level.
Do not hold the vehicle in place on slopes
by slipping or riding the clutch. Use the
handbrake instead, since a slipping clutch
increases clutch wear.<
Reverse
Select only when the vehicle is stationary.
Press the gearshift lever to the left to over-
come the resistance.
As you do this, the backup lamps will turn
on automatically when the ignition key is in
position 2.
Automatic transmission
with Steptronic*
You can drive as with a normal automatic
transmission. In addition, you can also shift
manually.
If you move the selector lever from position
D to the left into gearshift gate M/S, this
activates the sports-style shift programs of
the automatic transmission. As soon as you
move the selector lever slightly towards +
or Ð, the Steptronic shifts gear and manual
operation is activated. When you wish to
use the automatic transmission mode
again, move the selector lever to the right
into the D position.

M/S Manual mode and
Sport Program
Shifting from D into M/S activates the Sport
program and this is indicated with SD in the
gear display. The Sport Program is
designed for performance-oriented driving.
The first time the selector lever is even
slightly touched, the automatic transmis-
sion shifts from the Sport program into
manual operation.
If you start to move the selector lever
towards
+, the transmission shifts
upwards; moving it towards
Ð shifts down-
wards. The gear display shows M1 through
M5.
Upshifts and downshifts are executed only
when they will result in a plausible combi-
nation 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 will
