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

signal sounds: acute warning.
System indicates that you must
brake and/or manoeuvre the vehicle
yourself.
Advance warning
An advance warning is shown, for example if a
danger of collision is anticipated or there is a very short distance to a vehicle ahead.
The driver must intervene personally if there is
an advance warning.
Acute warning with braking function
An acute warning is shown in the event of an
immediate collision if the vehicle approaches
an object with relatively high differential speed.
The driver must intervene personally if there is
an acute warning. If necessary, the driver is as‐
sisted by slight automatic brake intervention if
there is a risk of collision.
An acute warning can be triggered even with‐
out a previous advance warning.
Brake interventionThe warning requires to take action yourself.
Maximum braking force is used during a warn‐
ing. In order for braking force support to be
used, it is necessary for the brake to be
pressed sufficiently quickly and powerfully. In
addition, the system may also support with a
small amount of braking if there is the risk of a

Audible warning signals An intermittent sound indicates position of an
object as the vehicle approaches it. For in‐
stance, if an object is identified to the rear left of the vehicle, the warning signal sounds from
the rear left loudspeaker.
The shorter the distance to an object be‐
comes, the shorter the intervals become.
If the distance to a detected object is less than
approximately 25 cm, 10 in, a continuous tone
sounds.

General driving information
Closing the boot lid WARNING
An open boot lid projects beyond the ve‐
hicle, and in the event of an accident, braking
or avoidance manoeuvres, it can endanger ve‐ hicle occupants and other road users, or dam‐
age the vehicle. There is also the danger of ex‐
haust fumes entering the interior of the
vehicle. Danger of injury or damage to prop‐
erty. Do not drive with the boot lid open.◀
If there is no alternative to driving with the tail‐
gate open:▷Close all windows and the Glass Roof.▷Turn up the blower to a high output level.▷Maintain moderate speed.
Hot exhaust system
WARNING
During driving, high temperatures can be
generated under the body, for example be‐
cause of the exhaust system. If flammable ma‐
terials, for example leaves of grass, come into
contact with hot parts of the exhaust system,
these materials can catch fire. Danger of injury
or damage to property.
Never remove the heat shields fitted here, or
apply underseal to them. Make sure that when driving, idling or parking, no flammable materi‐
als can come into contact with hot vehicle
parts. Do not touch the hot exhaust system.◀
Radio signals WARNING
Certain vehicle functions may be affec‐
ted by interference from high-frequency radio
signals. Such signals are output from a series
of transmission systems, for example, from air
traffic beacons or relay stations for mobile tele‐
communications.
We recommend you consult a Service Partner
or a qualified specialist workshop should you
experience any difficulties.◀
Mobile communication equipment WARNING
The vehicle's electronics and mobile
radio devices can interfere. The transmission
operation of mobile radio devices generates
radiation. Danger of injury or damage to prop‐
erty. If possible, only use mobile radio devices,
e.g. mobile telephones, in the interior with di‐
rect connection to an external antenna to ex‐
clude mutual interference and to dissipate the
radiation from the vehicle's interior.◀
Aquaplaning
On wet or slushy roads, a wedge of water can
form between the tyres and the road.
This situation, known as aquaplaning, means
that the tyre can actually lose contact com‐
pletely with the road surface and the vehicle
can neither be steered nor the brakes properly
applied.
Wading ATTENTION
Driving through excessively deep water
too fast can result in water entering the engine
compartment, electrical system or transmis‐
sion. Danger of damage to property. When
driving through water, do not exceed the maxi‐
mum specified water depth and maximum
fording speed.◀
Only if the water is calm and only up to a water
depth of max. 25 cm, approximately 9.8 inches
and at this depth drive no faster than walking
speed up to 5 km/h, approximately 3 mph.
