Gear shift indicator
The concept
The system recommends the most fuel efficient
gear for the current driving situation.
General information Depending on the vehicle's features and coun‐
try version of the vehicle, the gear shift indica‐
tor is active in the manual mode of the Step‐
tronic transmission and with manual
transmission.
Suggestions to shift gear up or down are dis‐
played in the instrument cluster.

Speed limit detection
The concept
Speed limit detection
Speed limit detection shows the current maxi‐
mum permitted speed in the instrument clus‐
ter. The camera at the base of the interior mir‐
ror detects traffic signs at the edge of the road
as well as variable overhead sign posts. Traffic
signs with extra symbols for wet road condi‐
tions, etc. are also detected and compared with
the vehicle's onboard data, such as for the rain
sensor, and will be displayed depending on the
situation.
With the navigation system, the system takes
into account the information stored in the navi‐
gation data and also displays speed limits pres‐
ent on routes without signs.
Without a navigation system, the system is sub‐
ject to limitations imposed by technology. Traf‐
fic signs with speed limitations are detected
and displayed only. Speed limitations due to
entering or exiting towns, highway signs, etc.
are not displayed. Speed limits with extra text
characters are always displayed.
Information
Speed limits when towing a trailer are not
shown.

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

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. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive 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.
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 rear luggage racks which are no longer
required 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 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.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.Seite 173Saving fuelDRIVING TIPS173
