Indicator
lamp
for
the
front-seat
passenger
airbags
The indicator lamp for the front-seat passenj ger airbags indicates the operating state of thefront-seat passenger airbags.
The lamp indicates whether the airbags are eij
ther activated or deactivated.
'yThe indicator lamp lights up
when a child is properly
seated in a child restraint fixj
ing system or when the seat
is empty. The airbags on the
front passenger side are not
activated.'yThe indicator lamp does not light up when, e.g., a correctly seated person of sufficient
size is detected on the seat. The airbags
on the front passenger side are activated.
Detected
child
seats
The system generally detects children seatedin a child seat, particularly in child seats rejquired by NHTSA at the point in time when thevehicle was manufactured. After installing achild seat, make sure that the indicator lampfor the front-seat passenger airbags lights up.
This indicates that the child seat has been dej tected and the front-seat passenger airbags
are not activated.
Strength
of
the
driver's
and
front-seat
passenger
airbag
The explosive power that activates driver's/
front passenger's airbags very much depends
on the positions of the driver's/front passengj er's seat.
To maintain the accuracy of this function over
the long term, calibrate the front seats as soon
as a respective message appears on the Conj
trol Display.
Calibrating
the
front
seats WARNING
There is a risk of jamming when moving
the seats. There is a risk of injury or risk of property damage. Make sure that the area ofmovement of the seat is clear prior to any adjjustment.'

WARNING
A damaged regular tire with low or missj
ing tire inflation pressure impacts handling, such as steering and braking response. Run-
flat tires can maintain limited stability. There is
a risk of an accident. Do not continue driving if
the vehicle is not equipped with run-flat tires.
Follow the information on run-flat tires and
continued driving with these tires.'

center or another qualified service center
or repair shop.2.Repair the flat tire, e.g., with a tire repair kit
or by changing the tire.
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.
System
limits
The system does not function properly if a rej
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.
The system cannot indicate sudden serious tire damage caused by external circumstances.
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 dej
tected.
Examples and recommendations in the followj
ing situations:
'yA wheel without TPM electronics is
mounted: Have it checked by a dealerss service center or another qualified service
center or repair shop as needed.'yMalfunction: Have system checked by a dealerss service center or another qualifiedservice center or repair shop.'yTPM was unable to complete the reset.Reset the system again.'yInterference caused by systems or devices
with the same radio frequency: After leavj ing the area of the interference, the system
automatically becomes active again.

Tire
Pressure
Monitoring
System
Each tire, including the spare (if provided)should be checked monthly when cold and injflated to the inflation pressure recommendedby the vehicle manufacturer on the vehicleplacard 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 presj
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 presj
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel efj 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 indij
cator to indicate when the system is not operj
ating properly. The TPMS malfunction indicaj
tor is combined with the low tire pressure
telltale. When the system detects a malfuncj
tion, the telltale will flash for approximately one
minute and then remain continuously illumij
nated. This sequence will continue upon subj
sequent vehicle start-ups as long as the malj
function exists. When the malfunction indicator
Seite 104ControlsSafety104
Online Edition for Part no. 01 40 2 974 681 - VI/16

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 replacej ment or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning propj
erly. Always check the TPMS malfunction tellj
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 Concept
The system detects tire inflation pressure loss on the basis of rotation speed differences bej
tween the individual wheels while driving.
In the event of a tire inflation pressure loss, the
diameter and therefore the rotational speed of
the corresponding wheel changes. This will be
detected and reported as a flat tire.
The system does not measure the actual inflaj
tion pressure in the tires.
Functional
requirements The system must have been initialized when
the tire inflation pressure was correct; otherj
wise, reliable flagging of a flat tire is not asj sured. Initialize the system after each correcjtion of the tire inflation pressure and afterevery tire or wheel change.
Status
display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, for examj ple, whether or not the FTM is active.1."Vehicle info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"
The status is displayed.
Initialization
When initializing, the set tire inflation presj
sures serve as reference values in order to dej
tect a flat tire. Initialization is started by conj
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 but 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 maneujvers.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
A natural, even tire inflation pressure loss in all
four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.

Sudden serious tire damage caused by exterj
nal circumstances cannot be recognized in adj vance.
The system could be delayed or malfunction in
the following situations:'yWhen the system has not been initialized.'yWhen driving on a snowy or slippery road
surface.'ySporty driving style: spinning traction
wheels, high lateral acceleration (drifting).'yWhen driving with snow chains.

Concept
The system can help prevent accidents. If an
accident cannot be prevented, the system will help reduce the collision speed.
The system sounds a warning before an immij
nent collision and actuates brakes independj
ently, if needed.
The automatic braking intervention is done with limited force and duration.
A camera in the area of the rearview mirror
controls the system.
The approach control warning is available even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the approach control warning and braking are delayed in order to avoid false sysj
tem reactions.
General
information The system warns at two levels of an imminentdanger of collision at speeds from approx.3 mph/5 km/h. Time of warnings may vary withthe current driving situation.
Appropriate braking kicks in at speeds of up to
35 mph/60 km/h.

ver.
Prewarning
This warning is issued, e.g., when there is the impending danger of a collision or the distanceto the vehicle ahead is too small.
The driver must intervene actively when there
is a prewarning.
Acute
warning
with
braking
function
Acute warning is displayed in case of the immij nent danger of a collision when the vehicle apj
proaches another object at a high differential
speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking interj
vention in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
Braking
intervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brakj
ing force is used. Prerequisite for the brake
booster is sufficiently quick and hard stepping on the brake pedal. The system can assist with
some braking intervention if there is a risk of a collision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: During a braking interj
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if vej
hicle stability has not been restricted, e.g., by
Seite 108ControlsSafety108

deactivating the DSC Dynamic Stability Conjtrol.
The braking intervention can be interrupted by stepping on the accelerator pedal or by acj
tively moving the steering wheel.
Object detection can be restricted. Observe
the limitations of the detection range and funcj tional restrictions.
