In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirements
The system must have been initialized when the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires can‐
not be detected. Therefore, check the tire infla‐
tion 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: slip in the drive wheels,
high lateral acceleration.▷When driving with snow chains.
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.
1."Vehicle Info"2."Vehicle status"3. "Flat Tire Monitor"
The status is displayed.
Initialization
The initialization process adopts the set inflation
tire pressures as reference values for the detec‐
tion of a flat tire. Initialization is started by con‐
firming the inflation pressures.
Do not initialize the system when driving with
snow chains.1."Vehicle Info"2."Vehicle status"3. "Reset"4.Start the engine - do not drive away.5.Start the initialization with "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.Check whether the vehicle is fitted with reg‐
ular tires or run-flat tires.
Run-flat tires, refer to page 162, are labeled
with a circular symbol containing the letters
RSC marked on the tire sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
Actions in the event of a flat tire
Normal tires
1.Identify the damaged tire.Seite 98ControlsSafety98
Online Edition for Part no. 01 40 2 903 813 - 07 12 490
Do this by checking the air pressure in all
four tires.
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.Rectify the flat tire on the damaged wheel.
Run-flat tires
Maximum speed
You can 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 the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx.
50 miles/80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e.g., curbs, potholes, etc.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending on the driving speed, road conditions,
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.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering prop‐
erties.◀
Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could
come loose and cause an accident. Do not con‐
tinue driving, and contact your service center. ◀
Lane departure warning
The concept
Starting at a specific speed, this system alerts
you when the vehicle on streets with lane mark‐
ings is about to leave the lane. Depending on the
country-specific version of the vehicle, the
speed is between 35 mph/55 km/h and
45 mph/70 km/h. When switching on the system
below this speed, a message appears in the in‐
strument cluster.
The steering wheel begins vibrating gently in the
event of warnings. The time of the warning may
vary depending on the current driving situation.
The system does not provide a warning if the
turn signal is set before leaving the lane.Seite 99SafetyControls99

Lamp and bulb replacement
Notes
Lamps and bulbs
Lamps and bulbs make an essential contribution
to vehicle safety.
The manufacturer of the vehicle recommends
that you entrust corresponding procedures to
the service center if you are unfamiliar with them
or they are not described here.
You can obtain a selection of replacement bulbs
at the service center.
Danger of burns
Only change bulbs when they are cool;
otherwise, there is the danger of getting
burned.◀
Working on the lighting system
When working on the lighting system, you
should always switch off the lights affected to
prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not perform work/bulb replacement on
xenon headlamps
Have any work on the xenon lighting system, in‐
cluding bulb replacement, performed only by a
service center. Due to the high voltage present
in the system, there is the danger of fatal injuries
if work is carried out improperly.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, as even minute amounts of
contamination will burn into the bulb's surface
and reduce its service life.
Use a clean tissue, cloth or something similar, or
hold the bulb by its base.◀Light-emitting diodes (LEDs)
Light-emitting diodes installed behind a cover
serve as the light source for controls, display el‐
ements and other equipment.
These light-emitting diodes, which are related
to conventional lasers, are officially designated
as Class 1 light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never stare
into the unfiltered light for several hours; other‐
wise, irritation of the retina could result.◀
Headlamp glass
Condensation can form on the inside of the ex‐
ternal lamps in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
lamp glasses do not need to be changed.
If the headlamps do not dim despite driving with
the light switched on, increasing humidity forms,
e. g. water droplets in the light, have the service
center check this.
