for example, a correctly seated person of
sufficient size is detected on the seat. The
airbags on the front passenger side are ac‐
tivated.
Detected child seats
The system generally detects children seated
in a child seat, particularly in child seats re‐
quired by NHTSA when the vehicle was manu‐ factured. After installing a child seat, make
sure that the indicator lamp for the front-seat
passenger airbags lights up. This indicates
that the child seat has been detected 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 passeng‐ er's seat.
With a respective message appearing on Con‐
trol Display calibrate the front seats to keep the accuracy of this function over the long-
term.
Calibrating the front seats WARNING
There is risk of jamming when moving
the seats. There is a risk of injury or risk of
property damage. Make sure that the area of
movement of the seat is clear prior to any ad‐
justment.◀

seat all the way forward, until it stops.2.Press the switch forward again. The seat
still moves forward slightly.3.Readjust the seat to the desired position.The calibration procedure is completed when
the message on the Control Display disap‐
pears.
If the message continues to be displayed, re‐
peat the calibration.
If the message does not disappear after a re‐
peat calibration, have the system checked as
soon as possible.
Tire Pressure Monitor TPM
The concept The system monitors tire inflation pressure in
the four mounted tires. The system warns you
if there is a significant loss of pressure in one
or more tires. For this purpose, sensors in the
tire valves measure the tire inflation pressure
and tire temperature.
Information With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 205.
Functional requirements
The system must have been reset with the
correct tire inflation pressure; otherwise, relia‐
ble signaling of tire inflation pressure loss is
not assured.
Reset the system after each adjustment of the
tire inflation pressure and after every tire or
wheel change.
Always use wheels with TPM electronics to
ensure that the system will operate properly.

WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-
flat tires can maintain limited stability. There is
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.◀
A low tire inflation pressure might turn on DSC
Dynamic Stability Control.
Actions in the event of a flat tire
Normal tires
1.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 initialized. In this case, initi‐
alize the system.
If identification of flat tire damage is not
possible, please contact a dealer’s 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, for example, the Mobility
System, may damage the TPM wheel electron‐
ics. In this case, have the electronics checked
at the next opportunity and have them re‐
placed if needed.
Run-flat tiresMaximum 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 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 shown to be correct, it is possible that
the Tire Pressure Monitor did not perform
a reset. Then perform the reset.
Possible driving distance with complete loss of
tire 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 differ‐
ently, for example, it has reduced lane stability
during braking, a longer braking distance and
different self-steering properties. Adjust your
driving style accordingly. Avoid abrupt steering
maneuvers or driving over obstacles, for exam‐
ple, curbs, potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be shorter or lon‐
ger depending on the driving speed, road con‐
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 is
reduced when braking, braking distances are
longer and the self-steering properties will
change. There is risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h.◀
Final tire failure
Vibrations or loud noises while driving can indi‐
cate the final failure of a tire.
Reduce speed and stop; otherwise, pieces of
the tire could come loose and cause an acci‐
dent.
Do not continue driving. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.
System limits
The system does not function properly if a re‐
set has not been carried out, for example, 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 de‐
tected.
Examples and recommendations in the follow‐
ing situations:▷A wheel without TPM electronics is
mounted: Have it checked by a dealer’s
service center or another qualified service
center or repair shop as needed.▷Malfunction: Have system checked by a
dealer’s service center or another qualified
service center or repair shop.Seite 111SafetyControls111

▷TPM was unable to complete the reset.
Reset the system again.▷Interference through systems or devices
with the same radio frequency: After leav‐
ing the area of the interference, the system
automatically becomes active again.
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 concept The system detects tire inflation pressure loss
on the basis of rotation speed differences be‐
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 infla‐
tion pressure in the tires.
Functional requirements
The system must have been initialized when
the tire inflation pressure was correct; other‐
wise, reliable flagging of a flat tire is not as‐
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, for exam‐
ple, whether or not the FTM is active.1."Vehicle info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"

Initialization
When initializing the once set inflation tire
pressures serve as reference values in order to
detect a flat tire. Initialization is started by con‐
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 - 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 maneu‐
vers.2.Check whether the vehicle is fitted with
normal tires or run-flat tires.
Run-flat tires, refer to page 212, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.
WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-
flat tires can maintain limited stability. There is
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.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if needed.
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 exter‐
nal circumstances cannot be recognized in ad‐
vance.
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: spinning traction
wheels, high lateral acceleration (drifting).▷When driving with snow chains.
Actions in the event of a flat tire
