Rear view camera*
The concept
The rear view camera in the liftgate displays the
area behind your vehicle on the Control Display.
Also check the traffic situation around the
vehicle during parking and maneuvering
with direct vision, as otherwise danger of an
accident could result, for example, from road
users or objects located outside the picture
area of the rear view camera.<

and liftgate are completely closed.
Pathway lines
The pathway lines are shown in the picture of
the rear view camera. They help you to estimate
the space required when parking and maneu-
vering on level roads.
To estimate the space required, turn the steer-
ing wheel so that the pathway lines guide into
the parking space or the maneuvering area you
have chosen.
The pathway lines are dependent on the current
steering angle and are continuously adjusted to
the steering wheel movements.
Turning lines
The static turning lines are displayed in the pic-
ture of the rear view camera and show you the
course of the smallest possible turning circle on
level roads.

Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
ABS is operational every time you start the
engine. Braking safely, refer to page129.
CBC Cornering Brake Control
When braking during curves or when braking
during a lane change, driving stability and steer-
ing response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.

9.Start to drive.
The initialization finishes during driving.
Indication of a flat tire
The warning lamp lights up red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
If you have deactivated DSC, it will be activated
automatically.
1.Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
In case of further air loss of the defective
wheel, its position will be indicated to you
on the Control Display.If the vehicle is not equipped with run-
flat tires as provided at the factory,
refer to page239, do not continue driving.
Continuing to drive with a flat tire could
cause severe accidents.<
2.At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
3.In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guide values:
>With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
>With a medium load:
2 persons, cargo bay full, or
4 persons without luggage:
approx. 95 miles/150 km
>With a full load:
4 or more persons, cargo bay full:
approx. 30 miles/50 km
Drive cautiously and do not exceed
speeds of 50 mph/80 km/h or else you
run the risk of causing an accident. In the event
of pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibrations or loud noises occur while
the vehicle is being driven, this can indicate final
failure of the damaged tire. Reduce speed and
stop at a suitable location as soon as possible,
otherwise pieces of the tire could become
detached and cause an accident. Do not con-
tinue driving, but instead contact the BMW
Sports Activity Vehicle Center.<

96 A message like this is displayed in the following
situations:
>In case of a malfunction:
Have the system checked
>If a wheel without TPM electronics is
mounted, e.g. a compact wheel
*
>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency
Explanation according to the NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare*, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires. As an added safety fea-
ture, your vehicle has been equipped with a tire
pressure monitoring system, TPMS, that illumi-
nates a low tire pressure telltale when one or
more of your tires are significantly under-
inflated. Accordingly, when the low tire pres-
sure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signif-
icantly underinflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability. Please note that the TPMS is not a
substitute for proper tire maintenance, and it is
the driver's responsibility to maintain correct
tire pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle startups as
long as the malfunction exists. When the mal-function indicator is illuminated, the system
may not be able to detect or signal low tire pres-
sure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.Active steering*
The concept
The active steering actively varies the steering
angle of the front wheels in relation to the steer-
ing wheel movements. In addition, it also varies
the steering force required for steering depend-
ing on the vehicle's speed.
When you are driving in the low road speed
range, e. g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes
very direct. In the higher speed range, on the
other hand, the steering angle is reduced more
and more. This improves the handling capability
of your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes.
Malfunction
The warning lamp lights up yellow
and a message is shown on the Con-
trol Display. The active steering is no
longer operational. At low speeds,
greater steering wheel movements are
required, whereas at higher speeds, the vehicle
reacts more sensitively to steering wheel move-
ments. The stability-promoting intervention
can also be deactivated. Proceed cautiously
and drive defensively. Have the system
checked.

Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Head airbags
3Side airbags
in backrests
Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page42.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.The airbags are deliberately not triggered in
every impact situation, e. g. less severe acci-
dents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way. Do not attempt to
remove the airbag restraint system from the
vehicle. Do not modify or tamper with either the
wiring or the individual components in the air-
bag system. This category includes the uphol-
stery in the center of the steering wheel, on the
instrument panel, the doors and the roof pillars
along with the sides of the headliner. Do not
attempt to remove or dismantle the steering
wheel. Do not touch the individual components
immediately after the system has been trig-
gered, because there is a danger of burns.
In the event of malfunctions, deactivation, or
triggering of the airbag restraint system, have
the testing, repair, removal, and disposal of air-
bag generators executed only by a BMW Sports
