Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable flagging of a flat tire is not as‐
sured. Initialize the system after each correc‐
tion of the tire inflation pressure and after
every tire or wheel change.
Status display The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.
On the Control Display:1."Vehicle info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"
The status is displayed.
Initialization
When initializing the once set inflation tire
pressures serve as reference values in order to
detect a flat tire. Initialization is started by con‐
firming the tire inflation pressures.
Do not initialize the system when driving with
snow chains.
On the Control Display:
1."Vehicle info"2."Vehicle status"3. "Perform reset"4.Start the engine - do not drive off.5.Start the initialization with "Perform reset".6.Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Indication of a flat tire The yellow warning lamp lights up. A
Check Control message is displayed.
There is a flat tire or a major loss in tire inflation
pressure.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Identify the damaged wheel. Do so by
checking the tire inflation pressure using
the Mobility System. If the tire inflation
pressure in all tires is correct, the Flat Tire
Monitor may not have been initialized. In
this case, initialize the system.3.Repair flat tire with the Mobility System or
replace the damaged wheel.
System limits
Sudden tire damage
Sudden serious tire damage caused by
external circumstances cannot be recognized
in advance.◀
A natural, even tire inflation pressure loss in all
four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.
The system could be delayed or malfunction in
the following situations:
▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: spinning traction
wheels, high lateral acceleration (drifting).▷When driving with snow chains.
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

▷Arrows: at least one lane marking was de‐
tected and warnings can be issued.
Issued warning
If you leave the lane and if a lane marking has
been detected, the steering wheel begins vi‐
brating.
If the turn signal is set before changing the
lane, a warning is not issued.
End of warning
The warning ends:
▷Automatically after approx. 3 seconds.▷When returning to your own lane.▷When braking hard.▷When using the turn signal.
System limits
The system may not be fully functional in the
following situations:
▷In heavy fog, rain or snowfall.▷In the event of missing, worn, poorly visi‐
ble, merging, diverging, or multiple lane
markings such as in construction areas.▷When lane markings are covered in snow,
ice, dirt or water.▷In tight curves or on narrow lanes.▷When the lane markings are covered by
objects.▷When driving very close to the vehicle in
front of you.▷When driving toward bright lights.▷When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.▷During calibration of the camera immedi‐
ately after vehicle shipment.Active Blind Spot Detection
The concept
Two radar sensors below the rear bumper
monitor the area behind and next to the vehicle
at speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehi‐
cles in the blind spot, arrow 1, or approaching
from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing is dim‐
med.
Before you change lanes after setting the turn
signal, the system issues a warning in the sit‐
uations described above.
The lamp in the exterior mirror housing flashes
and the steering wheel vibrates.
Hints Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise acci‐
dents are still possible despite all warnings.◀

Driving comfortVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
Cruise controlThe concept
The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, e.g.:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀

Ventilation
Front ventilation▷Thumbwheel to vary the temperature, ar‐
row 1.

Toward red: warmer.
The set interior temperature for the driver
and passenger are not changed.▷Lever for changing the air flow direction,
arrow 2.▷Thumbwheels for opening and closing the
vents continuously, arrows 3.
Adjusting the ventilation
▷Ventilation for cooling:
Direct vent in your direction when vehicle's
interior is too hot.▷Draft-free ventilation:
Adjust the vent to let the air flow past you.
Parked-car ventilation
The concept The parked-car ventilation ventilates the vehi‐
cle interior and lowers its temperature, if
needed.
Operation can be performed via iDrive.
Functional requirements
Parked-car ventilation▷Using the preset reel-on time or when op‐
erated directly: any external temperature.
Open the vents to allow air to flow out.

Changing wheels
Hints
When sealants are used, an immediate wheel
change when there is a loss of tire inflation
pressure in the event of a flat tire is unneces‐
sary.
Which is why no spare tire is available.
The tools for changing wheels are available as
accessories from your service center.
