AdjustingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Sitting safely
The ideal seating position can make a vital con‐
tribution to relaxed, fatigue-free driving.
The seating position plays an important role in
an accident in combination with:▷Safety belts, refer to page 54.▷Head restraints, refer to page 55.▷Airbags, refer to page 98.
Seats
Adjusting
General information Do not adjust the seat while driving
Do not adjust the driver's seat while driv‐
ing, or the seat could respond with unexpected
movement and the ensuing loss of vehicle con‐
trol could lead to an accident.◀
Do not incline the backrest too far to the
rear
Also on the front passenger side, do not incline
the backrest on the front passenger side too far
to the rear during driving, or there is a risk of
slipping under the safety belt in the event of an
accident. This would eliminate the protection
normally provided by the belt.◀

▷Results in a relaxed seating position.▷Reduces strain on the shoulder muscles.
Active seat
Active adjustment of the seat cushion's con‐
tours reduces muscular tension and fatigue to
help prevent lower back pain.
Press the button. The LED lights up.
Front seat heating
Switching on Press the button once for each temper‐
ature level.
The maximum temperature is reached when
three LEDs are lit.
If the drive is continued within approx. 15 mi‐
nutes, the seat heating is activated automati‐
cally with the temperature selected last.
When ECO PRO, refer to page 170, is activated,
the heater output is reduced.
Switching off Press the button longer.
The LEDs go out.
Temperature distribution
The heating action in the seat cushion and back‐
rest can be distributed in different ways.1."Climate"2."Seat heating distribution"3.Select the required seat.4.Turn the controller to set the temperature
distribution.
Active seat ventilation, front
The seat cushion and backrest surfaces are
cooled by means of integrated fans.
The ventilation rapidly cools the seat, e. g., if the
vehicle interior is overheated or for continuous
cooling at high temperatures.

Switching onPress the button once for each ventila‐
tion level.
The highest level is active when three LEDs are
lit.
If when the seat ventilation is turned on the Max‐
imum Cooling function is activated, the seat
ventilation automatically switches to the highest
level. When the Maximum Cooling function is
switched off, the unit switches back to the pre‐
viously set level.
After a short time, the system automatically
moves down one level in order to prevent ex‐
cessive cooling.
Switching off Press the button longer.
The LEDs go out.
Safety belts
Seats with safety belt
The vehicle has four seats, each of which is
equipped with a safety belt.
Notes
Always make sure that safety belts are being
worn by all occupants before driving away.
Although airbags enhance safety by providing
added protection, they are not a substitute for
safety belts.
One person per safety belt
Never allow more than one person to wear
a single safety belt. Never allow infants or small
children to ride on a passenger's lap.◀
Putting on the belt
Lay the belt, without twisting, snugly
across the lap and shoulders, as close to the
body as possible. Make sure that the belt lies low
around the hips in the lap area and does not
press on the abdomen. Otherwise, the belt can
slip over the hips in the lap area in a frontal im‐
pact and injure the abdomen.
The safety belt must not lie across the neck, rub
on sharp edges, be routed over solid or breaka‐
ble objects, or be pinched.◀
Reduction of restraining effect
Avoid wearing clothing that prevents the
belt from fitting properly, and pull the shoulder
belt periodically to readjust the tension across
your lap; otherwise, the retention effect of the
safety belt may be reduced.◀
Buckling the belt
Make sure you hear the latch plate engage in the
belt buckle.
Unbuckling the belt
1.Hold the belt firmly.2.Press the red button in the belt buckle.3.Guide the belt back into its reel.Seite 54ControlsAdjusting54

Safety belt reminder for driver's seat
and front passenger seat
The indicator lamp flashes or lights up
and a signal sounds. Make sure that the
safety belts are positioned correctly.
The safety belt reminder is active at speeds
above approx. 5 mph/8 km/h. It can also be ac‐
tivated if objects are placed on the front pas‐
senger seat.
Damage to safety belts
In the case of strain caused by accidents or
damage:
Have the safety belts, including the safety belt
tensioners, replaced and have the belt anchors
checked.
Checking and replacing safety belts
Have the work performed only by your
service center; otherwise, it cannot be ensured
that this safety feature will function properly.◀
Head restraints (front)
Correctly adjusted head restraint
A correctly adjusted head restraint reduces the
risk of injury to cervical vertebrae in the event of
an accident.
Adjusting the head restraint
Correctly adjust the head restraints of all
occupied seats; otherwise, there is an increased
risk of injury in an accident.◀
Height
Adjust the head restraint so that its center is ap‐
proximately at ear level.
Distance
Adjust the distance so that the head restraint is
as close as possible to the back of the head.Active head restraint
In the event of a rear-end collision with a certain
severity, the active head restraint automatically
reduces the distance from the head.
Reduced protective function▷Do not use seat or head restraint cov‐
ers.▷Do not hang objects, e.g., clothes hangers,
on the head restraints.▷Only attach accessories approved by BMW
to the seat or head restraint.
Otherwise, the protective function of the active
head restraint will be impaired and the personal
safety of the occupants will be endangered.◀

equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for

The right place for children
Note Children in the vehicle
Do not leave children unattended in the
vehicle; otherwise, they could endanger them‐
selves and other persons, e.g., by opening the
doors.◀
Children should always be in the rear
Accident research shows that the safest place
for children is in the back seat.
Transporting children in the rear
Only transport children younger than
13 years of age or shorter than 5 ft/150 cm in the
rear in child restraint fixing systems provided in
accordance with the age, weight and size of the
child; otherwise, there is an increased risk of in‐
jury in an accident.
Children 13 years of age or older must wear a
safety belt as soon as a suitable child restraint
fixing system can no longer be used, due to their
age, weight and size.◀
Children on the front passenger seat
Should it ever be necessary to use a child re‐
straint fixing system in the front passenger seat,
make sure that the front, knee and side airbags
on the front passenger side are deactivated. Au‐tomatic deactivation of front passenger airbags,
refer to page 99.
Deactivating the front passenger airbags
If a child restraint fixing system is used in
the front passenger seat, the front passenger
airbags must be deactivated; otherwise, there is
an increased risk of injury to the child when the
airbags are triggered, even with a child restraint
fixing system.◀
Installing child restraint fixing
systems
Notes Manufacturer's information for child re‐
straint fixing systems
To select, mount and use child restraint fixing
systems, observe the information provided by
the system manufacturer; otherwise, the pro‐
tective effect can be impaired.◀
On the front passenger seat
Deactivating airbags
After installing a child restraint fixing system in
the front passenger seat, make sure that the
front, knee and side airbags on the front pas‐
senger side are deactivated.
Deactivate the front passenger airbags auto‐
matically, refer to page 99
Deactivating the front passenger airbags
If a child restraint fixing system is used in
the front passenger seat, the front passenger
airbags must be deactivated; otherwise, there is
