▷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‐
sequent vehicle start-ups as long as the mal‐
function exists. When the malfunction indicator
is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace‐
ment or alternate tires or wheels on the vehicleSeite 114ControlsSafety114

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
Remove auxiliary mirrors, 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
thereby reduces the range.
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.Seite 195Saving fuelDriving tips195

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.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 consist of tires that are self-sup‐
porting, to a limited degree, and possibly spe‐
cial rims.
The support of the sidewall allows the tire to
remain 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.
Your service center will be glad to advise you.
Mobility System
The concept With the Mobility System, minor tire damagecan be sealed quickly to enable continued
travel. To accomplish this, sealant is pumped

No cleansers that contain alcohol or sol‐
vents
Do not use cleansers that contain alcohol or
solvents, such as lacquer thinners, heavy-duty
grease removers, fuel, or such; this could lead
to surface damage.◀
Safety belts
Dirty belt straps impede the reeling action and
thus have a negative impact on safety.
Chemical cleaning
Do not clean chemically; this can destroy
the webbing.◀
Use only a mild soapy solution, with the safety
belts clipped into their buckles.
Do not allow the reels to retract the safety
belts until they are dry.
Carpets and floor mats No objects in the area around the pedals
Keep floor mats, carpets, and any other
objects out of the pedal area; otherwise, the
function of the pedals could be impeded while
driving and create the risk of an accident.
Do not place additional floor mats over existing
mats or other objects.
Only use floor mats that have been approved
for the vehicle and can be properly attached to
floor.
Ensure that the floor mats are securely fas‐
tened again after they were removed for clean‐
ing, e.g.◀
Floor mats can be removed from the car's inte‐
rior for cleaning.
If the floor carpets are very dirty, clean with a
microfiber cloth and water or a textile cleaner.
To prevent matting of the carpet, rub back and
forth in the direction of travel only.Sensor/camera lenses
To clean sensors and camera lenses, use a
cloth moistened with a small amount of glass
detergent.
Displays/monitors Cleaning displays and screens
Do not use any chemical or household
cleaning agents; otherwise, surfaces can be af‐
fected.◀
Keeping out moisture
Keep all fluids and moisture away from
the unit; otherwise, electrical components can
be damaged.◀
Avoid pressure
Avoid pressing too hard when cleaning
and do not use abrasive materials; otherwise,
damage can result.◀
Clean with a clean, antistatic microfiber cloth.
Long-termWhen the vehicle is shut down for longer than
three months, special measures must be
taken. Additional information is available from
the service center.Seite 254MobilityCare254
