wheel change.1.Start the engine - do not drive off.2. Press button.3. "Vehicle Info"4."Vehicle status"5."Tire Pressure Monitor (TPM)"6.To reset the tire pressure: "Perform reset"7.Drive away.
"Resetting…" is displayed.
After driving faster than 19 mph/30 km/h for a
short period, the set tire inflation pressures are
accepted as reference values. The resetting
process is completed automatically while driv‐
ing.
You may interrupt this trip at any time. When
you continue the reset resumes automatically.
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.▷A reset of the system was not carried out
after a wheel was changed. The system
therefore issues a warning based on the tire
pressures before the last reset.1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 184, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.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. ◀
A low tire inflation pressure might turn on DSC
Dynamic Stability Control.
Actions in the event of a flat tire
Normal tires1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
The tire pressure gauge of the Mobility Sys‐
tem, refer to page 185, can be used for this
purpose.
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.Fix the flat tire using the Mobility System,
refer to page 185.
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 maneu‐
vers.2.Do not exceed a speed of 50 mph/80 km/h.Seite 82CONTROLSSafety82
Online Edition for Part no. 01 40 2 961 140 - II/15
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 re‐
set. Then perform the reset.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on cargo load, driv‐
ing 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 differently,
e.g., it has reduced lane stability during brak‐
ing, 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.
Because the possible driving distance depends
on how the vehicle is used during the trip, the
actual distance may be shorter or longer 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.
Your car handles differently when you lose tire
inflation pressure, e.g., your lane stability is re‐
duced when braking, braking distances are lon‐
ger and the self-steering properties will
change. ◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of a tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving and contact your service
center. ◀
Required inflation pressure check
message
A Check Control message is displayed in the fol‐
lowing situations▷The system has detected a wheel change,
but no reset was done.▷Inflation was not carried out according to
specifications.▷The tire inflation pressure has fallen below
the level of the last confirmation.
In this case:
▷Check the tire pressure and correct as
needed.▷Carry out a reset of the system after a tire
change.
System limits
The system does not function properly if a reset
has not been carried out, e.g., a flat tire is re‐
ported though tire inflation pressures are cor‐
rect.
The tire inflation pressure depends on the tire's
temperature. Driving or exposure to the sun
will increase the tire's temperature, thus in‐
creasing the tire inflation pressure. The tire in‐
flation pressure is reduced when the tire tem‐ perature falls again. These circumstances may
cause a warning when temperatures fall very
sharply.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire pressure can be detected.
Display in the following situations:
▷A wheel without TPM electronics, such as
an emergency wheel, is mounted: have the
service center check it if needed.▷Malfunction: have the system checked by
your service center.Seite 83SafetyCONTROLS83

tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents. ◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if needed.
System limits Sudden tire damage
Sudden serious tire damage caused by
external circumstances cannot be recognized in
advance. ◀
A natural, even tire inflation pressure loss in all
four tires will not be recognized. Therefore,
check the tire inflation pressure regularly.
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.

Wheels and tiresVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Tire inflation pressure Safety informationThe tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the tire inflation pressure
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 stabil‐
ity, but also lead to tire damage and the risk of
an accident. ◀
Tires have a natural, consistent loss of tire infla‐
tion pressure.
Tires heat up while driving, and the tire inflation
pressure increases along with the tire's temper‐
ature. The tire inflation pressure specifications
relate to cold tires or tires with the ambient
temperature.
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.
The displays of inflation devices may under-
read by up to 1.45 psi/0.1 bar.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire Moni‐
tor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.▷Reinitialize the Flat Tire Monitor.▷Reinitialize the Tire Pressure Monitor.
Checking the inflation pressure of the
emergency wheel
Located behind the bumper on the underside
of the vehicle is an opening for checking the
tire inflation pressure.
Pressure specifications
The tire inflation pressure table, refer to
page 177, 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 page 82.5.Replace the damaged tires as soon as pos‐
sible.
Driving with emergency wheel
Watch the speed when driving with the
emergency wheel
Drive conservatively and do not exceed a speed
of 50 mph/80 km/h; otherwise, changed driving
characteristics such as reduced lane stability
while braking, extended braking distance and
changed self-steering properties in the limit
area. ◀
Mount one emergency wheel only
Only a single emergency wheel may be
mounted. Reinstall wheels and tires of the orig‐
inal size as quickly as possible; otherwise, there
is a safety risk. ◀

Maintenance
The battery is maintenance-free, i.e., the elec‐
trolyte will last for the life of the battery.
Your service center will be glad to advise you
on questions regarding the battery.
Battery replacement Use approved vehicle batteries only
Only use vehicle batteries that have been
approved for your vehicle by the manufacturer;
otherwise, the vehicle could be damaged and
systems or functions may not be fully availa‐
ble. ◀
After a battery replacement, have the battery
registered on the vehicle by your service center
to ensure that all comfort features are fully
available and that any Check Control messages
are no longer displayed.
Charging the battery
General information Make sure that the battery is always sufficiently
charged to guarantee that the battery remains
usable for its full service life.
The battery may need to be charged in the fol‐
lowing cases:▷When making frequent short-distance
drives.▷If the vehicle is not used for prolonged peri‐
ods, longer than a month.▷Steptronic transmission: when parked for
long periods of time in selector lever posi‐
tion D, R or N.
