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

they achieve their full traction potential after a
break-in time.
Drive conservatively for the first
200 miles/300 km.
Retreaded tires The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
WARNING
Retreaded tires can have different tire
casing structures. With advanced age the serv‐
ice life can be limited. There is risk of an acci‐
dent. The manufacturer of your vehicle does
not recommend the use of retreaded tires. ◀
Winter tires Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires provide
better winter traction than summer tires, they
do not provide the same level of performance
as winter tires.
Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then a respective symbol is displayed in your
field of vision. The label is available from a
dealer’s service center or another qualified
service center or repair shop.
With mounted winter tires, observe and adhere
to the permissible maximum speed.
Run-flat tires If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in the
case of a flat tire. Further information is availa‐
ble from a dealer’s service center or another
qualified service center or repair shop.Rotating wheels between axles
Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated between
the axles to achieve even wear. Further infor‐
mation is available from a dealer’s service cen‐
ter or another qualified service center or repair
shop. After rotating, check the tire pressure and
correct if needed.
Storage Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Run-flat tires
Label
RSC label on the tire sidewall.
The wheels are composed of tires that are self-
supporting to a limited degree.
The support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the
event of a tire inflation pressure loss.
Follow the instructions for continued driving
with a flat tire.

Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
A dealer’s service center will be glad to answer
additional questions at any time.
Repairing a flat tireSafety measures▷Park the vehicle as far away as possible
from passing traffic and on solid ground.▷Switch on the hazard warning system.▷Secure the vehicle against rolling away by
setting the parking brake.▷Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.▷Have all vehicle occupants get out of the
vehicle and ensure that they remain out‐
side the immediate area in a safe place,
such as behind a guardrail.▷If necessary, set up a warning triangle at an
appropriate distance.
Mobility System
The concept
With the Mobility System, minor tire damage
can be sealed temporarily to enable continued
travel. To accomplish this, sealant is pumped
into the tires, which seals the damage from the
inside.
The compressor can be used to check the tire
inflation pressure.
Information
▷Follow the instructions on using the Mobi‐
lity System found on the compressor and
sealant container.▷Use of the Mobility System may be ineffec‐
tive if the tire puncture measures approx.
1/8 in/4 mm or more.▷Contact a dealer’s service center or another
qualified service center or repair shop if the
tire cannot be made drivable.▷If possible, do not remove foreign bodies
that have penetrated the tire.▷Pull the speed limit sticker off the sealant
container and apply it to the steering
wheel.▷The use of a sealant can damage the TPM
wheel electronics. In this case, have the
electronics checked at the next opportunity
and have them replaced if needed.
DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of the
vehicle. There is danger to life. Keep the ex‐
haust pipe free and ensure sufficient ventila‐
tion. ◀
Storage
The Mobility System is located under the cargo
floor panel.
