Flat Tire Monitor FTMThe Flat Tire Monitor signals a loss of
tire inflation pressure in a tire.
Reduce your speed and stop cau‐
tiously. Avoid sudden braking and steering ma‐
neuvers.
For more information, see Flat Tire Monitor, re‐
fer to page 114.
Tire Pressure Monitor TPM Illuminated: the Tire Pressure Monitor
signals a loss of tire inflation pressure
in a tire.
Reduce your speed and stop cautiously. Avoid
sudden braking and steering maneuvers.
Flashing and then continuously illuminated: no
flat tire or loss of tire inflation pressure can be
detected.▷Interference through systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.▷TPM could not conclude the reset: perform
the reset of the system again.▷A wheel without TPM electronics is fitted:
have the service center check it if needed.▷Malfunction: have the system checked by
your service center.
For more information, see Tire Pressure Moni‐
tor, refer to page 111.
Steering system Steering system in some cases defec‐
tive.
Have the steering system checked by
the service center.
Engine functions Have the vehicle checked by the serv‐ice center.
For additional information, refer to On-board
Diagnostics socket, refer to page 221.
Lane departure warning System is switched on and under cer‐
tain circumstances warns if a detected
lane is left without flashing beforehand.
For additional information, refer to Lane depar‐
ture warning, refer to page 129.
Green lights Turn signal Turn signal on.
Unusually rapid flashing of the indicator
lamp indicates that a turn signal bulb
has failed.
For additional information, refer to Turn signal,
refer to page 75.

vated.
For additional information, refer to

Actions in the event of a flat tire
Normal tires1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
The tire pressure gage of the Mobility Sys‐
tem, refer to page 208, can possibly be
used for this purpose.
If the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor may not
have been initialized. In this case, initialize
the system.
If an identification is not possible, please
contact the service center.2.Fix the flat tire where applicable using the
Mobility System, refer to page 208.
Run-flat tires
Maximum speed
You may continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at
the next opportunity.
If the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor may not
have been initialized. In this case, initialize
the system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on cargo load, driv‐
ing style and road conditions.
A vehicle with an average load has a possible
driving range of approx. 50 miles/80 km.
A vehicle with a damaged tire reacts differ‐
ently, e.g., it has reduced lane stability during
braking, a longer braking distance and different
self-steering properties. Adjust your driving
style accordingly. Avoid abrupt steering ma‐
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be shorter or lon‐
ger depending on the driving speed, road con‐
ditions, external temperature, cargo load, etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
Your car handles differently when you lose tire
inflation pressure, e.g., your lane stability is re‐
duced when braking, braking distances are
longer and the self-steering properties will
change.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of a tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving and contact your service
center.◀
Intelligent Safety
The concept Intelligent Safety enables central operation of
the driver assistance system.
Depending on how the vehicle is equipped, In‐
telligent Safety consists of one or more sys‐
tems that can help prevent a imminent colli‐
sion. These systems are active automatically
every time the engine is started using the
Start/Stop button:▷Front-end collision warning, refer to
page 117.▷Pedestrian warning, refer to page 123.Seite 116ControlsSafety116

Camera
The camera lens is located under the BMW
emblem of the tail gate. The image quality may
be impaired by dirt. The camera calibrates it‐
self regularly after the system has been
switched off. This is why the emblem on the
tailgate remains open after the system has
been deactivated and while driving. The em‐
blem closes automatically as soon as calibra‐
tion is complete.
Clean the camera lens, refer to page 236.
Switching on/off
Switching on automatically With the engine running, engage lever in posi‐
tion P R.
The rearview camera image is displayed if the
system was switched on via the iDrive.
Automatic deactivation during forward
travel
The system switches off when a certain driving
distance or speed is exceeded.
Switch the system back on if needed.
Switching on/off manually Press button.
▷On: the LED lights up.▷Off: the LED goes out.

space is needed when parking and maneu‐
vering on level pavement.▷They are dependent on the current steer‐
ing angle and are continuously adjusted to
the steering wheel movements.Seite 154ControlsDriving comfort154

Visual warning
The approach of the vehicle to an object can
be shown on the Control Display.
When the distance to an object is small, a red
bar is shown in front of the vehicle, as it is in
the PDC display.
The display appears as soon as Top View is
activated.
When the image of the rearview camera is dis‐
played, it is possible to reel to top view:

Displaying the turning radius and
pathway lines
▷The static, red turning radius line shows
the space needed to the side of the vehicle
when the steering wheel is turned all the
way.▷The variable, green pathway line assists
you in assessing the amount of space ac‐
tually needed to the side of the vehicle.
The lane line depends on the engaged
gear and the current steering angle. TheSeite 158ControlsDriving comfort158
