Launch Control
Principle
Launch Control allows optimum acceleration
when driving off on a non-slip road surface.
General
Using Launch Control leads to preliminary component wear, as this function represents a
very heavy load for the vehicle.
Do not use Launch Control when running in,
see page 162.
Requirements
Launch Control is available with an engine at
operating temperature, so after an uninterrup‐
ted drive of at least 10 km, approximately
6 miles.
To start with Launch Control, do not engage
the steering wheel.
Activating Launch Control1.Deactivate Dynamic Stability Control, see
page 124.2.Select sequential mode with gear 1 and
drive program 3.3.With the engine running, depress the brake
with the left foot.4.Depress accelerator pedal fully.
The engine speed when driving off is regu‐
lated.
The flag symbol appears in the instrument
cluster.5.Using the Cruise Control, change the en‐
gine speed when driving off by 500 rpm.6.Release brake, vehicle accelerates. Con‐
tinue to press accelerator pedal.
Upshifting happens automatically as long
as the accelerator pedal is fully depressed.
Launch Control is only available again after a
certain distance has been travelled.

Tyre Pressure Monitor TPM
Principle The system monitors the tyre pressure in the
four fitted tyres. The system warns if the infla‐
tion pressure in one or more tyres has fallen
considerably. To do this, the sensors in the
tyre valves measure the tyre pressure and tyre
temperatures.
Note
To operate the system, also follow the other
information and notes under tyre inflation pres‐
sure, see page 175.
Operating requirements For the system, a reset must have been made
with the correct tyre inflation pressure, other‐
wise reliable signalling of a flat tyre cannot be assured.
Reset the system after adjusting the tyre pres‐
sure to a new value and after a tyre or wheel
change.
Always use wheels with TPM electronics to
guarantee the system functions without errors.
Status display
The current status of the Tyre Pressure Moni‐
tor TPM can be shown on the Control Display,
for example whether the TPM is active.
On the Control Display:1."Vehicle information"2."Vehicle status"3. "Tyre Pressure Monitor (RDC)"
The status is displayed.
Status control display The tyre and system status is denoted by the
wheel colour and some text on the Control Dis‐
play.

sure in several tyres.
Wheels grey
The system cannot detect a flat tyre. The rea‐
sons for this are:▷System reset is performed.▷Malfunction.
Additional information
The current tyre inflation pressures and, de‐
pending on the model, tyre temperatures are
also displayed in the status control display.
The values shown are current values and may
change due to the effect of driving mode or
weather conditions.
Running reset Reset the system after adjusting the tyre pres‐
sure to a new value and after a tyre or wheel
change.
On the Control Display and on the vehicle:
1."Vehicle information"2."Vehicle status"3. "Perform reset"4.Start the engine – do not drive off.5.Resetting tyre pressure: "Perform reset".6.Drive off.
The wheels are shown grey and the status ap‐
pears on the display.

cepted as target values. The reset is run auto‐
matically while the vehicle is in motion.
After a successfully concluded reset, the
wheels are shown in green on the Control Dis‐
play and "Tyre Pressure Monitor (RDC)
active." is shown.
You can interrupt your drive at any time. Reset
resumes automatically when you continue
your journey.
Message if tyre inflation pressure is
low
The yellow warning lamp is illuminated.
A Check Control message is shown.▷There is a flat tyre or substantial
loss of tyre pressure.▷No reset has been done to the system.
Consequently, the system warns of the
tyre pressures of the last reset.1.Reduce your speed and carefully stop the
vehicle. Avoid violent or sudden braking
and steering manoeuvres.2.Determine which wheel is damaged. Do
this by checking the tyre inflation pres‐
sures with the aid of the Mobility System.
Correcting the tyre inflation pressure3.Remedy the flat tyre with the Mobility Sys‐
tem or replace the damaged wheel.
When there is a message that the tyre inflation
pressure is low, the Dynamic Stability Control
DSC may be switched on.
Message with required tyre inflation
pressure test
In such situations, a check control message is
displayed:
▷System has detected a wheel change, but
no reset has been run.▷Filling was not performed according to the
regulations.▷The tyre inflation pressure has dropped
compared to the last confirmation.If that is the case:▷Check the tyre pressure and adjust as nec‐
essary.▷Reset the system after a wheel change.
System limits
The system is not working correctly if no reset
has been run, for example, a flat tyre is repor‐
ted in spite of the correct tyre inflation pres‐
sure.
Tyre inflation pressure depends on the tem‐
perature of the tyre. By increasing tyre temper‐
ature, for example, when driving or with solar
radiation, the tyre inflation pressure increases.
Tyre inflation pressure decreases if the tyre
temperature drops. Through this behaviour, a
warning may be triggered if there are major
temperature drops, due to the given warning
limits.
No warning can be given by the system of ex‐
treme, sudden tyre failure caused by external
factors.
Malfunction The yellow warning lamp flashes and is
then illuminated continuously. A Check
Control message is shown. No flat
tyres or loss of tyre pressure can be detected.
This may indicate one of the following:
▷Wheel without TPM electronics is fitted:
have the vehicle checked by a Service
Partner or a qualified specialist workshop if
necessary.▷Malfunction: have the system checked by a
Service Partner or a qualified specialist
workshop.▷TPM has not completed a reset. Run a re‐
set of the system again.▷Fault due to systems or devices with the
same frequency: the system is automati‐
cally reactivated upon leaving the field of
interference.Seite 108ControlsSecurity108

Runflat indicator RPA
Principle The system identifies a loss of tyre pressure
by comparing the speeds of rotation of the in‐
dividual wheels while the vehicle is in motion.
If a tyre loses pressure, its diameter changes.
This in turn alters the rotational speed of the
corresponding wheel. This is detected and re‐
ported as a flat tyre.
The system does not measure the tyre pres‐
sures as such.
Operating requirements
The system must have been initialised with
correct tyre inflation pressure, otherwise relia‐
ble signalling of a flat tyre cannot be assured.
Each time the tyre pressure is adjusted or a
tyre or wheel is changed, initialise the system
again.
Status display The current status of the runflat indicator can
be shown on the Control Display, for example
whether the runflat indicator is active.
On the Control Display:1."Vehicle information"2."Vehicle status"3. "Flat Tyre Monitor (RPA)"
The status is displayed.
Initialising
On initialisation, the current tyre pressures are
stored as a reference for detection of a flat tyre. The initialisation is started by confirming
the correct tyre inflation pressures.
When driving with snow chains fitted, do not
initialise the system.
On the Control Display:
1."Vehicle information"2."Vehicle status"3. "Perform reset"4.Start the engine – do not drive off.5.Start the initialisation with "Perform reset".6.Drive off.
Initialising is completed while the vehicle is in
motion; this process can be interrupted at any
time.
Initialising resumes automatically when you
continue your journey.
Message of a flat tyre The yellow warning lamp is illuminated.
A Check Control message is shown.
There is a flat tyre or substantial loss of
tyre pressure.
1.Reduce your speed and carefully stop the
vehicle. Avoid violent or sudden braking
and steering manoeuvres.2.Determine which wheel is damaged. Do
this by checking the tyre inflation pres‐
sures with the aid of the Mobility System. If
all tyres are inflated to the correct pres‐
sures, the runflat indicator might not have
been initialised. In this case initialise the
system.3.Remedy the flat tyre with the Mobility Sys‐
tem or replace the damaged wheel.
System limits
A natural, even loss of tyre pressurein all four
tyres that occurs over time is not detected.
Consequently, check the tyre inflation pres‐
sure at regular intervals.
No warning can be given in the event of sud‐
den tyre failure caused by external factors.
In the following situations, the system could be
slow to respond or operate incorrectly:
▷If the system has not been initialised.▷Journey on snow-covered or slippery sur‐
faces.Seite 109SecurityControls109
Online Edition for Part no. 01 40 2 964 013 - VI/15

▷On returning to the correct lane.▷With strong braking.▷On indicating.
System limits
The function can be restricted, for example in
the following situations:
▷In thick fog and heavy rain or snow.▷With missing, worn, poorly visible, merg‐
ing/separating or ambiguous boundary
lines, for example in areas where there are
road works.▷If boundary lines are covered by snow, ice,
dirt or water.▷On sharp bends or narrow roads.▷If the boundary lines are not white.▷If boundary lines are obscured.▷If the vehicle is moving too close to the ve‐
hicle ahead.▷With bright oncoming light.▷When the windscreen in front of the rear-
view mirror is covered with condensation,
dirt, stickers, labels, etc.▷During the calibration process of the cam‐
era immediately after the vehicle is sup‐
plied.Lane change warning
Principle
Two radar sensors in the rear bumper monitor
the area behind and beside the vehicle as of
approx. 20 km/h, approx.12 mph.
In some equipment configurations, the radar
sensors are active from approximately
50 km/h, approximately 30 mph.
The system indicates when vehicles are in the
blind spot, arrow 1, or are approaching from
the rear on an adjacent lane, arrow 2.
The light in the exterior mirror housing illumi‐
nates at a dimmed level.
Before changing lanes with the turn indicator
switched on, the system issues a warning the
above situations.
The light in the exterior mirror housing flashes
and the steering wheel vibrates.
Notes WARNING
The system does not take your personal
responsibility from you when you are estimat‐
ing the visibility conditions and traffic situation.
Danger of accidents. Adapt driving style to the
driving conditions. Observe the traffic situation
and intervene actively if the situation warrants
it.◀

Manual speed limiterPrinciple With the system, the speed can be restricted
from a value of 30 km/h/20 mph. There are no
restrictions below the set speed limit.
Exceeding the speed limit In particular situations the speed limit can be
deliberately exceeded by accelerating strongly.
The system gives a warning if the travelling
speed exceeds the set speed limit.
No brake intervention
If the set speed limit has been reached or unin‐
tentionally exceeded (for example driving
downhill) there is no brake intervention.
