WARNING
If the seat position is incorrect or the dej
ployment area of the airbags is impaired, the airbag system cannot protect as intended ormay cause additional injuries due to triggering.
There is a risk of injuries or danger to life. Folj
low the information on optimum protective efj fect of the airbag system.'

WARNING
Improperly executed work can lead to
failure, malfunction or unintentional triggering of the airbag system. In the case of a malfuncj
tion, the airbag system might not trigger as inj
tended in the event of an accident despite rej
spective accident severity. There is a risk of injuries or danger to life. Have the airbag sysj
tem checked, repaired, dismantled and scrapj ped by a dealerss service center or anotherqualified service center or repair shop.'

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.'

Run-flat tires, refer to page 204, are laj
beled with a circular symbol containing the letters RSC marked on the tire's sidewall.
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.'

Actions
in
the
event
of
a
flat
tire
Normal
tires1.Identify the damaged tire.
Check the air pressure in all four tires, e.g., using the tire pressure gage of a tire repair
kit.
If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. In this case, perform the reset.
If identification of flat tire damage is not possible, please contact a dealerss service
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.
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 maneuj vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires atthe next opportunity.
If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. In this case, perform the reset.
Possible driving distance with complete loss oftire inflation pressure:
The possible driving distance with a flat tire
depends on cargo load, driving 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 differj
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 maj
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
Because the possible driving distance dej pends on how the vehicle is used during the trip, the actual distance may be shorter or lonj
ger depending on the driving speed, road conj ditions, external temperature, cargo load, etc.
WARNING
Your vehicle handles differently when a
run-flat tire is damaged and has low or missing tire inflation pressure, e.g., your lane stability isreduced when braking, braking distances arelonger and the self-steering properties will
change. There is a risk of an accident.
Drive moderately and do not exceed a speed of50 mph/80 km/h.'

The tire inflation pressure depends on thetire'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.

NHTSA/
FMVSS

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
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.Seite 108ControlsSafety108

FTM
Flat
Tire
MonitorConcept
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, 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 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.Check whether the vehicle is fitted with
normal tires or run-flat tires.
Run-flat tires, refer to page 204, are laj
beled with a circular symbol containing the letters RSC marked on the tire's sidewall.
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.'

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
