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 vehicle
that prevent the TPMS from functioning prop‐
erly. Always check the TPMS malfunction tell‐
tale 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.
FTM Flat Tire Monitor The conceptThe system detects a pressure loss on the ba‐sis of speed differences between the individual
wheels while driving.
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.
The system does not measure the actual infla‐
tion pressure in the tires.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable signaling of a flat tire is not en‐Seite 102ControlsSafety102

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.1."Vehicle Info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"
The status is displayed.
Initialization
The initialization process adopts the set infla‐
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains.

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
regular tires or run-flat tires.
Run-flat tires, refer to page 197, are la‐
beled 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.
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
cannot be detected. 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: slip in the drive
wheels, high lateral acceleration.▷When driving with snow chains.
Actions in the event of a flat tire
Normal tires
1.Identify the damaged tire.
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.Seite 103SafetyControls103

Collision warning
Depending on how the equipment is equipped,
the collision warning system consists of one of
the two systems:▷Collision warning with City Braking func‐
tion, refer to page 105;▷Collision warning with braking function, re‐
fer to page 108
Collision warning with City
Braking function
The concept The system can help to prevent accidents. If
an accident cannot be prevented, the system
helps to reduce the collision speed.
The system issues a warning if there is immi‐
nent danger of a collision and if so brakes inde‐
pendently.
The automatic braking intervention is done
with limited force and duration.
The system is controlled via a camera in the
base of the mirror.
The collision warning is available even if cruise
control has been deactivated.
When the vehicle is intentionally brought close
to a vehicle, the collision warning is delayed to
avoid false warnings.
General information
The system issues a two-phase warning of a
danger of collision with vehicles at speeds
above approx. 3 mph/5 km/h. The time of these
warnings may vary depending on the current
driving situation.
Up to approx. 35 mph/60 km/h a braking inter‐
vention occurs when appropriate.

Braking intervention
The warning prompts the driver himself to in‐
tervene. During a warning, the maximum brak‐
ing force is used. A prerequisite for the brake
booster is a sufficiently fast and sufficiently
strong actuation of the brake pedal. In addition,
if there is a risk of collision, the system can as‐
sist with a slight braking intervention. The in‐ tervention can bring a vehicle traveling at slow
speed to a complete stop.
Manual transmission: During a braking inter‐
vention up until reaching a complete stop, the
engine may be shut down.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
The braking intervention can be interrupted by
pressing on the accelerator pedal or by actively
moving the steering wheel.
Tow-starting and towing
When tow-starting and towing the vehi‐
cle, switch off the Intelligent Safety systems;
otherwise, improper behavior of the braking
function of individual systems could result in
an accident.◀
System limits
Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the dan‐
ger of an accident occurring.◀
Detection range
The system's detection capabilities are limited.
This may result in the warning not being is‐
sued or being issued late.
For example, the following situations may not
be detected:▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.▷Pedestrians.

Warning stages
Prewarning
This warning is issued, for example, when
there is the impending danger of a collision or
the distance to the vehicle ahead is too small.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention is executed with lim‐
ited braking force and for a brief period only.
The intervention can bring the vehicle to a
complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
Above approx. 130 mph/210 km/h, the braking
intervention occurs as a brief braking pressure.
No automatic delay occurs.
Adapting your speed and driving style

Pedestrian warning with citybraking function
The concept
The system can help to prevent accidents with
pedestrians.
The system issues a warning in the city driving
speed area if there is imminent danger of a col‐
lision with pedestrians and includes a braking
function.
The system is controlled via the camera in the
base of the interior mirror.
General information The system issues a warning with brightness
staring at approx. 6 mph/10 km/h to approx.
35 mph/60 km/h regarding a possible risk of
collision with pedestrians and assists with a
brake intervention shortly before a collision.
It responds to persons that are within the de‐
tection range of the system.
Detection range
The detection area in front of the vehicle is div‐
ided into two areas.
▷Central area, arrow 1, directly in front of the
vehicle.▷Expanded area, arrow 2, to the right and
left.Seite 110ControlsSafety110
Online Edition for Part no. 01 40 2 926 810 - X/13
A collision is imminent if pedestrians are lo‐
cated within the central area. A warning is is‐
sued about pedestrians who are located within
the extended area only if they are moving in
the direction of the central area.

fall.▷In tight curves.▷If the camera view field or the front wind‐
shield are dirty or covered.▷When driving toward bright lights.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop knob.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷When it is dark outside.
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.
Notes 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.◀
