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.

In these cases:
Reduce your speed and stop cautiously. Avoid
sudden braking and steering maneuvers.
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.'

If identification of flat tire damage is notpossible, please contact a dealerss servicecenter 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 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.
Intelligent
Safety The
conceptIntelligent Safety enables central operation of
the driver assistance system.
Depending on how the vehicle is equipped, Inj
telligent Safety consists of one or more sysj tems that can help prevent a imminent collijsion. These systems are active automaticallyevery time the engine is started using the
Start/Stop button:'yFront-end collision warning with City Brakj
ing function, refer to page 111.'yPedestrian warning, refer to page 113.
Safety
information
WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sysj
tem may not be output or they may be output
too late or incorrectly. There is a risk of an acj
cident. Adjust the driving style to the traffic conditions. Watch traffic closely and activelyintervene in the respective situations.'
