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 a
compact wheel, is mounted: have the serv‐
ice center check it if needed.▷Malfunction: have the system checked by
your service center.▷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

Saving fuelVehicle 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.
General information Fuel consumption depends on a number of dif‐
ferent factors.
The implementation of certain measures, driv‐
ing style and regular maintenance can influ‐
ence fuel consumption and environmental im‐
pact.
Remove unnecessary
cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Remove roof or rear luggage racks which are
no longer required following use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Close the windows and
glass sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
raises fuel consumption.
Tires
General information Tires can affect fuel consumption in various
ways, e.g., tire size may influence fuel con‐
sumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away without de‐
lay
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the fastest way for the cold engine to
reach its operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.Seite 159Saving fuelDRIVING TIPS159

Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
With proper use, these tires meet the highest
standards for safety and handling.
New tires
Tire traction is not optimal due to manufactur‐
ing circumstances when tires are brand-new;
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.
Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety. ◀
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. You can obtain this sign from the
tire specialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for
the respective winter tires; otherwise, tire dam‐
age and accidents can occur. ◀
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. Your service center will be
glad to advise you.
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. Your service center will be
glad to advise you.
After rotating, check the tire pressure and cor‐
rect 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.Seite 180MOBILITYWheels and tires180
