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 of
movement of the seat is clear prior to any ad‐
justment.◀
The indicator lamp for the front-seat passen‐
ger airbags indicates the operating state of the
front-seat passenger airbags.
The lamp indicates whether the airbags are ei‐
ther activated or deactivated.
A corresponding message appears on the
Control Display.

The indicator lamp lights up
when a child is properly
seated in a child restraint fix‐
ing system or when the seat
is empty. The airbags on the
front passenger side are not
activated.
1. Press the switch and move the respective
seat all the way forward.
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‐

▷
The 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.
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.
Detected child seats
The system generally detects children seated
in a child seat, particularly in child seats re‐
quired by NHTSA at the point in time when the
vehicle was manufactured. 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 de‐
tected and the front-seat passenger airbags
are not activated.
Tire Pressure Monitor TPM
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.

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
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.◀

Safety
Controls
Check the air pressure in all four tires, e.g.,
using the tire pressure gage of a tire repair
kit.
A vehicle with a damaged tire reacts differ‐
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 ma‐
neuvers or driving over obstacles, e.g., curbs,
potholes, etc.
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.
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.
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.
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 a risk of an accident.
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
Drive moderately and do not exceed a speed of
50 mph/80 km/h.◀
Maximum speed
You may continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Final tire failure
Vibrations or loud noises while driving can indi‐
cate the final failure of a tire.
Continued driving with a flat tire
Reduce speed and stop; otherwise, pieces of
the tire could come loose and cause an acci‐
dent.
If continuing to drive with a damaged tire:
1. Avoid sudden braking and steering maneu‐
vers.
Do not continue driving. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.
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.
System limits
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.
The system does not function properly if a re‐
set has not been carried out, e.g., a flat tire is
reported though tire inflation pressures are
correct.
Possible driving distance with complete loss of
tire inflation pressure:
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
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.

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.
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.
