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 224, can possibly be
used for this purpose.
If the tire inflation pressure in all four tires
is shown to be correct, it is possible that
the Tire Pressure Monitor did not perform
a reset. Then perform the reset.
If an identification is not possible, please
contact the service center.2.Fixing a flat tire, where applicable with the
Mobility System.
Use of tire sealant, e.g., the Mobility System,
may damage the TPM wheel electronics. In
this case, have the electronics checked at the
next opportunity and have them replaced if
needed.
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 shown to be correct, it is possible that
the Tire Pressure Monitor did not perform
a reset. In that case, carry out a reset.
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.◀
Required tire inflation pressure check
message
A Check Control message is displayed in the
following situations▷The system has detected a wheel change,
but no reset was done.▷Inflation was not carried out according to
specifications.Seite 113SafetyControls113
Online Edition for Part no. 01 40 2 954 312 - II/15

▷The tire inflation pressure has fallen below
the level of the last confirmation.
In this case:
▷Check the tire pressure and correct as
needed.▷Carry out a reset of the system after a tire
change.
System limits
The system does not function properly if a re‐
set has not been carried out, e.g., a flat tire is
reported though tire inflation pressures are
correct.
The tire inflation pressure depends on the
tire's temperature. Driving or exposure to the
sun will increase the tire's temperature, thus
increasing the tire inflation pressure. The tire
inflation pressure is reduced when the tire
temperature falls again. These circumstances
may cause a warning when temperatures fall
very sharply.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire inflation pressure can be de‐
tected.
Display in the following situations:
▷A wheel without TPM electronics is fitted:
have the service center check it if needed.▷Malfunction: have the system checked by
your service center.▷TPM was unable to complete the reset.
Reset the system again.▷Interference through systems or devices
with the same radio frequency: after leav‐
ing the area of the interference, the system
automatically becomes active again.Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation 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 feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres‐
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel ef‐
ficiency and tire tread life, and may affect the
vehicle's handling and stopping 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. Your vehicle has also
been equipped with a TPMS malfunction indi‐
cator to indicate when the system is not oper‐
ating properly. The TPMS malfunction indica‐
tor is combined with the low tire pressure
telltale. When the system detects a malfunc‐
tion, the telltale will flash for approximately one
minute and then remain continuously illumi‐
nated. This sequence will continue upon sub‐
sequent vehicle start-ups as long as the mal‐
function exists. When the malfunction indicator
is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace‐
ment or alternate tires or wheels on the vehicleSeite 114ControlsSafety114

System limitsSudden 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.

Night Vision with Pedestrian
and Animal Detection
The concept Night Vision with pedestrian and animal detec‐
tion is a night vision system.
An infrared camera scans the area in front of
the vehicle and issues a warning if it detects
pedestrians and animals on the street. Warm
objects that are similar in shape to human be‐
ings or animals are detected by the system. If necessary, the heat image can be displayed on
the Control Display.
Heat image
The image shows the heat radiated by objects
in the field of view of the camera.
Warm objects have a light appearance and
cold objects, a dark appearance.
The ability to detect an object depends on the
temperature difference between the object
and the background and on the level of heat
radiation emitted by the object. Objects that
are similar in temperature to the environment
or that radiate very little heat are difficult to de‐
tect.
For safety reasons, when driving at speeds
above approx. 3 mph/5 km/h and in low ambi‐
ent light, the image is only displayed when the
low beams are activated.
A still image is displayed at regular intervals for
a fraction of a second.
Pedestrian and animal detection
Object detection and warning only functions in
darkness.
Warm objects that are similar in shape to hu‐
man beings are detected by the system.
In addition, the system also detects animals
above a certain minimum size, e.g., deer.
With heat image activated on the Control Dis‐
play:
People detected by the system are displayed
with a slight yellow hue.
Animals detected by the system are displayed
in a darker yellow.
Under good ambient conditions, the object de‐
tection operates within the following distance
ranges:
Seite 126ControlsSafety126
Online Edition for Part no. 01 40 2 954 312 - II/15

▷Pedestrian detection: up to approx.
330 ft/100 m▷Detection of large animals: up to approx.
490 ft/150 m▷Detection of medium animals: up to ap‐
prox. 230 ft/70 m
Environmental influences can limit the availa‐
bility of object detection.
If the vehicle systems detect that the vehicle is
located in a residential area, the animal detec‐
tion is temporarily switched off.
Hints Personal responsibility
Night Vision cannot replace the driver's
personal judgment of the visibility conditions
and the traffic situation. The view ahead and
the actual visibility conditions must always be
the basis on which the vehicle speed is ad‐
justed; otherwise, there is a risk to road
safety.◀

Display in the Head-up DisplayThe warning is displayed simultane‐
ously in the Head-up Display and on
the instrument cluster. The displayed
symbol can vary with the people detected.
When animals are detected, an animal symbol
is displayed.
System limits
Basic limits
System operation is limited in situations such
as the following:▷On steep hills, in steep depressions or in
tight curves.▷When the camera is dirty or the protective
glass is damaged.▷In heavy fog, rain or snowfall.▷At very high external temperatures.
Limits of pedestrian and animal
detection
In some situations, it may occur that pedes‐
trians are detected as animals or animals as
pedestrians.
Small animals are not detected by the object
detection function, even if they are clearly visi‐
ble in the image.
Limited detection:
▷People or animals who are fully or partially
covered, especially when their heads are
covered.▷People who are not in an upright position,
e.g., lying down.▷Cyclists on unconventional bicycles (e.g.,
recumbent bicycles).▷After physical damage to the system, e.g.,
after an accident.
No display on the rear screen
The image from Night Vision cannot be dis‐
played on the rear screen.
Lane departure warning
The concept Starting at a specific speed, this system alerts
you when the vehicle on streets with lane
markings is about to leave the lane. This
speed, depending on the country version, is
between 35 mph/55 km/h and
45 mph/70 km/h.
When switching on the system below this
speed, a message is displayed in the instru‐
ment cluster.
The steering wheel begins vibrating gently in
the event of warnings. The time of the warning
may vary depending on the current driving sit‐
uation.
The system does not provide a warning if the
turn signal is set before leaving the lane.
Hints Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the
course of the road and the traffic situation.
In the event of a warning, do not jerk the steer‐
ing wheel, as you may lose control of the vehi‐
cle.◀
