Required tire inflation pressure check
message
A Check Control message is displayed in the
following 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 re‐
set has not been carried out, e.g., a flat tire is
reported though tire inflation pressures are
correct.
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
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 inflation pressure can be de‐
tected.
Display in the following situations:
▷A wheel without TPM electronics is fitted:
have the service center check it if needed.▷Malfunction: have the system checked by
your service center.▷TPM was unable to complete the reset.
Reset 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
system (TPMS) that illuminates a low tire pres‐
sure telltale when one or more of your tires is
significantly 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 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‐

Saving fuelVehicle features and optionsThis 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
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
General information Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
Carrying out certain measures, such as a mod‐
erate driving style and regular maintenance,
can influence fuel consumption and the envi‐
ronmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.
Closing the windows Open windows increase air resistance and
therefore lead to greater 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 immediately
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 quickest way of warming the cold
engine up to operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and proactively reduces fuel
consumption.
Avoid high engine speeds
As a rule: driving at low engine speeds lowers
fuel consumption and reduces wear.
Use 1st gear to get the vehicle moving. Start‐
ing with the 2nd gear, accelerate rapidly. WhenSeite 173Saving fuelDriving tips173

Wheels and tiresVehicle features and options
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
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Tire inflation pressure Safety information
The 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 pres‐
sure, and correct it as needed: at least twice a
month and before a long trip. If you fail to ob‐
serve this precaution, you may be driving on
tires with incorrect tire pressures, a condition
that may not only compromise your vehicle's
driving stability, but also lead to tire damage
and the risk of an accident.◀
Tires have a natural, consistent loss of tire in‐
flation pressure.
Tires heat up while driving, and the tire infla‐
tion pressure increases along with the tire's
temperature. The tire inflation pressure speci‐
fications 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
Monitor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.
Tire inflation 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. Tire inflation pressure
specifications apply to approved tire sizes and
recommended tire brands. This information
can be obtained from your service center.
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.

Approved wheels and tires
You should only use wheels and tires
that have been approved by the vehicle manu‐
facturer for your vehicle type; otherwise, e.g.,
despite having the same official size ratings,
variations can lead to chassis contact and with
it, the risk of severe accidents
The manufacturer of your vehicle cannot eval‐
uate non-approved wheels and tires to deter‐
mine if they are suited for use, and therefore
cannot guarantee the operating safety of the
vehicle.◀
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 pro‐
vide better winter traction than summer tires, they do not provide the same level of perform‐
ance 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 axlesDifferent wear patterns can occur on the frontand 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 correct if needed.
Rotating the tires is not permissible on vehi‐
cles with different tire sizes or rim sizes on the
front and rear axles.Seite 193Wheels and tiresMobility193

3.Wrap the empty sealant container and con‐
nection hose in suitable material to avoid
dirtying the cargo area.4.Stow the Mobility System back in the vehi‐
cle.
Distributing the sealant
Immediately drive approx. 5 miles/10 km to en‐
sure that the sealant is evenly distributed in the
tire.
Do not exceed a speed of 50 mph/80 km/h.
If possible, do not drive at speeds less than
12 mph/20 km/h.
To correct the tire inflation pressure
1.Stop at a suitable location.2.Screw the connection hose onto the tire
valve stem.3.Attach the connection hose directly to the
compressor.4.Insert the connector into a power socket
inside the vehicle.5.Correct the tire inflation pressure to
2.5 bar.▷Increase pressure: with the ignition
turned on or the engine running, reel
on the compressor.▷To reduce the pressure: press the but‐
ton on the compressor.
Continuing the trip
Do not exceed the maximum permissible
speed of 50 mph/80 km/h.
Reinitialize the Flat Tire Monitor.
Reinitialize the Tire Pressure Monitor.
Replace the defective tire and the sealant con‐
tainer of the Mobility System as soon as possi‐
ble.
Snow chains Fine-link snow chains
Only certain types of fine-link snow chains
have been tested by the manufacturer of the
vehicle, classified as road-safe and approved.
Information about the approved snow chains
are available from the service center.
