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 ormore tires. For this purpose, sensors in the tire
valves measure the tire inflation pressure.
Information With use of the system observe further infor‐
mation found under Tire inflation pressure, re‐
fer to page 186.
Functional requirements The system must have been reset with the cor‐
rect tire inflation pressure; otherwise, reliable
signaling of tire 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 en‐
sure that the system will operate properly.

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
normal tires or run-flat tires.
Run-flat tires, refer to page 193, 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. Fol‐
low the information on run-flat tires and con‐
tinued driving with these tires. ◀

Actions in the event of a flat tireNormal 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, initialize
the system.
If identification of flat tire damage is not
possible, please contact a dealer’s serviceSeite 110CONTROLSSafety110
Online Edition for Part no. 01 40 2 969 276 - II/16
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 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.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 with a flat tire de‐
pends 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 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.
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.
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.Seite 111SafetyCONTROLS111
Online Edition for Part no. 01 40 2 969 276 - II/16
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.
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 pressure can be detected.
Examples and recommendations in the follow‐
ing situations:▷A wheel without TPM electronics, for exam‐
ple an emergency wheel, 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.▷TPM was unable to complete the reset. Re‐
set 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 sys‐
tem (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is signifi‐
cantly 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 pressure. Driving
on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Un‐
der-inflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle's han‐
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte‐
nance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-in‐
flation has not reached the level to trigger illu‐
mination 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 properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi‐
mately one minute and then remain continu‐
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as in‐
tended. TPMS malfunctions may occur for a va‐
riety of reasons, including the installation of re‐
placement 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.Seite 112CONTROLSSafety112

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
WARNING
A tire with low or missing tire inflation
pressure impacts handling, such as steering
and braking response. There is risk of an acci‐
dent. Regularly check the tire inflation pressure,
and correct it as needed, e.g., twice a month and before a long trip. ◀
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 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.
Pressure specifications
The tire inflation pressure table, refer to
page 187, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pres‐
sure values apply to tire sizes approved by the
manufacturer of the vehicle for the vehicle
type.
To identify the correct tire inflation pressure,
please note the following:
▷Tire sizes of your vehicle.▷Maximum permitted 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
values in the tire inflation pressure table, refer
to page 187, and adjust as necessary.
