▷Do not place objects under the seat that
could press against the seat from below.
Indicator lamp for the front passenger
airbags
The indicator lamp for the front passenger air‐
bags indicates the operating state of the front
passenger airbags.
The lamp indicates whether the airbags are ac‐
tivated or deactivated.
▷The indicator lamp lights up
when a child who is properly
seated in a child restraint fix‐
ing system intended for that
purpose is detected on the
seat or the seat is empty. The
airbags on the front passen‐
ger side are not activated.▷The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient size is detected on the seat. The
airbags on the front passenger side are ac‐
tivated.
The system generally detects children seated in
a child seat, especially in the child seats that
were required by NHTSA when the vehicle was
manufactured. After installing a child seat, make
sure that the indicator lamp for the front pas‐
senger airbags lights up. This indicates that the
child seat has been detected and the front pas‐
senger airbags are not activated.
Strength of the driver's and front
passenger airbag
The strength with which the driver's and front
passenger airbags are triggered depends on the
position of the driver's and front passenger
seats.
To maintain the accuracy of this function over
the long-term, calibrate the front seats when a
corresponding message appears on the Control
Display.
Calibrating the front seats
A corresponding message appears on the Con‐
trol Display.1.Move the respective seat forward all the
way.2.Move the respective seat forward again. It
moves forward briefly.3.Readjust the seat to the desired position.
The calibration procedure is completed when
the message on the Control Display disappears.
If the message continues to be displayed, repeat
the calibration.
If the message does not disappear after a repeat
calibration, have the system checked as soon as
possible.
Unobstructed area of movement
Ensure that the area of movement of the
seats is unobstructed to avoid personal injury or
damage to objects.◀
Tire Pressure Monitor TPM*
The concept
The tire inflation pressure is measured in the
four mounted tires. The system notifies you if
there is a significant loss of pressure in one or
more tires.
Functional requirements
The system must have been reset when the in‐
flation pressure was correct; otherwise, reliable
signaling of a flat tire is not ensured. Always use
wheels with TPM electronics to ensure that the
system will operate properly. Reset the system
after each correction of the tire inflation pres‐
sure and after every tire or wheel change.

Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
The system does not operate correctly if it has
not been reset. For example, a flat tire may be
indicated despite correct tire inflation pres‐
sures.
The system is inactive and cannot indicate a flat
tire:▷For a mounted wheel without TPM electron‐
ics.▷When the TPM is disturbed by other sys‐
tems or devices with the same radio fre‐
quency.

After driving for a few minutes, the set tire infla‐
tion pressures are applied as set values. The re‐
setting process is completed automatically dur‐
ing driving. The tires are shown in green and
"TPM active" is shown on the Control Display.
The trip can be interrupted at any time. If you
drive away again, the process resumes auto‐
matically.
If a flat tire is detected during a reset, all tires are
displayed in yellow.
Low tire pressure message 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.▷The system was not reset after a wheel
change and thus warns based on the infla‐
tion pressures initialized last.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with reg‐
ular tires* or run-flat tires*.
Run-flat tires, refer to page 213, are labeled
with a circular symbol containing the letters
RSC marked on the tire sidewall.
When a low inflation pressure is indicated, DSC
Dynamic Stability Control is switched on if nec‐
essary.
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 Tire Pressure Monitor may not
have been initialized. In this case, initialize
the system.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire on the damaged wheel.
Use of tire sealant, e.g., the Mobility System,
may damage the TPM wheel electronics. In
this case, have the electronics checked atSeite 8383

the next opportunity and have them re‐
placed if necessary.
Run-flat tires*
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
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.◀
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
correct, the Tire Pressure Monitor may not
have been initialized. In this case, initialize
the system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx. 50 miles/
80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e.g., curbs, potholes, etc.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending on the driving speed, road conditions,
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.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering prop‐
erties.◀
Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of the tire. Reduce speed
and stop; otherwise, pieces of the tire could
come loose and cause an accident. Do not con‐
tinue driving, and contact your service center. ◀
Message when the system was not
reset
A Check Control message is displayed.
The system detected a wheel change
but was not reset.
Warnings regarding the current tire inflation
pressure are not reliable.
Check the tire inflation pressure and reset the
system.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. A flat tire
cannot be detected.
Display in the following situations:▷A wheel without TPM electronics is fitted:
have the service center check it if necessary.▷Malfunction: have the system checked by
your service center.▷TPM could not be fully reset. Reset the sys‐
tem again.▷Disturbance by systems or devices with the
same radio frequency: after leaving the area
of the disturbance, the system automatically
becomes active again.
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 la‐
bel, you should determine the proper tire infla‐
tion pressure for those tires.) As an added safety
feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that il‐
luminates a low tire pressure telltale when one
or more of your tires is significantly under-in‐
flated. 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 pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping
ability. Please note that the TPMS is not a sub‐
stitute 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 indicator to
indicate when the system is not operating prop‐
erly. The TPMS malfunction indicator is com‐
bined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will
flash for approximately one minute and then re‐
main continuously illuminated. This sequence
will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the mal‐
function 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
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re‐
placement or alternate tires and wheels allow
the TPMS to continue to function properly.Brake force display*

Wheels and tiresTire inflation pressure
Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the pressure
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours. When the tires
are warm, the tire inflation pressure is higher.
Check the tire inflation pressure regularly
Regularly check the tire inflation pressure
and correct it as needed: at least twice a month
and before a long trip. If you fail to observe this
precaution, you may be driving on tires with in‐
correct tire pressures, a condition that may not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.◀
After correcting the tire inflation pressure, rein‐
itialize the Tire Pressure Monitor.
Pressure specifications
The tire inflation pressure table, refer to
page 207, contains all pressure specifications
for the specified tire sizes at the ambient tem‐
perature. Pressure specifications apply to ap‐
proved tire sizes and recommended tire brands.
This information can be obtained from your
service center.
To identify the correct tire inflation pressure,
please note the following:
▷Tire sizes of your vehicle.▷Vehicle load.▷Maximum allowable driving speed.Tire inflation pressures up to 100 mph/
160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure val‐
ues in the tire inflation pressure table, refer to
page 207, and adjust as necessary.
These pressure values can also be found on the
tire inflation pressure label on the driver's door
pillar.
Maximum permissible speed
Do not exceed 100 mph/160 km/h; other‐
wise, tire damage and accidents may result.◀
