DRIVER SUPPORT
Limitations of Road Sign
Speed limiter
A speed limiter (SL35) can be likened to a
reverse cruise control - the driver regulates
the speed using the accelerator pedal but is
prevented from accidentally exceeding a pre-
selected/set maximum speed by the speed
limiter.
Information*
The RSI function may interpret some types
of bicycle rack, connected to the electrical
socket for trailers, as a connected trailer. In
such cases, the driver display may show
incorrect speed information.
The Road Sign Information (RSI32) function
may have limitations in certain situations.
Examples of what can reduce the function are
as follows:
Faded signs
•
•
•
•
•
Signs positioned on bends
Rotated or damaged signs
Signs positioned high above the roadway
This function uses the car's camera and
radar units, which have certain general lim-
itations.
Fully/partially obscured or poorly posi-
tioned signs

Signs completely or partly covered with
frost, snow and/or dirt

curate or have no speed information34

Limitations for speed limiter
Speed limiter (SL39) has certain general limi-

•
The speed limiter (SL38) can be temporarily
deactivated and set in standby mode.
•
•
On steep downhill gradients the speed limit-
er’s braking effect may be inadequate and
hence the stored maximum speed may be
exceeded. In this case, the driver is alerted by
the message Speed limit exceeded in the
driver display.
The speed limiter can also be temporarily
deactivated and overridden with the accelera-
tor pedal without the speed limiter first having
to be set in standby mode - e.g. to be able to
quickly accelerate the car out of a situation.
In which case, proceed as follows:
1. Fully depress the accelerator pedal and
release it to interrupt acceleration when
the desired speed has been reached.
A text message that the maximum speed is
exceeded will be activated if the speed has
been exceeded by at least 3 km/h
(approx. 2 mph).
> In this mode, the speed limiter is still
activated and the driver display's sym-
bol is therefore WHITE.

2. Fully release the accelerator pedal when
the temporary acceleration is finished.
•
> The car is then engine-braked automat-
ically to below the last stored maximum
speed.

Automatic speed limiter
Symbol for automatic speed limiter
The sign symbol (displayed along-
side the stored speed, "70", in the
centre of the speedometer) can be
shown in three colours with the fol-
lowing meanings:
WARNING
The Automatic Speed Limiter (ASL40) func-
tion helps the driver to adapt the car's maxi-
mum speed to the speed shown on the road
signs.
The function is supplementary driver
support intended to facilitate driving
and make it safer – it cannot handle all
situations in all traffic, weather and
road conditions.
•
•
The Speed Limiter function (SL41) can be
changed to Automatic Speed Limiter (ASL).
The driver is advised to read all sec-
tions in the Owner's Manual that relate
to this function to learn about factors
such as its limitations and what the
driver should be aware of before using
the system.
Colour of
Meaning
The automatic speed limiter uses speed infor-
mation from the Road Sign Information*
(RSI42) function to automatically adapt the
car's maximum speed.
sign symbol
Greenish yel- The automatic speed limiter

Grey
The automatic speed limiter

WARNING
Driver support functions are not a sub-
stitute for the driver's attention and

•
Even if the driver clearly sees the speed-
related road sign, the speed information
from the Road Sign Information* (RSI)
function to ASL may be incorrect – in such
cases the driver must intervene him/herself
and accelerate or brake to a suitable speed.
Orange
Automatic speed limiter is
in temporary standby mode
- e.g. due to a road sign not
being read.
Symbol for which speed limiter
function is active
The symbol display in the driver display
changes depending on whether it is cruise
control or automatic cruise control that is
active.

Deactivating the automatic speed
limiter
To deactivate the automatic speed limiter:
Changing the tolerance for the
automatic speed limiter
–
Press the steering wheel button
(1)
until 70 km/h (43 mph) in the centre of
the speedometer (2) changes to 75 km/h
(47 mph).
The Automatic Speed Limiter function
(ASL46) can be set for different tolerance lev-
els. The tolerance is adjusted in the same way
as the speed setting is in the speed limiter.
If, for example, the car follows a signed speed
limit of 70km/h (43 mph) the driver can
instead choose to allow the car to maintain
75 km/h (47 mph).
–
Tap on the button in the function view.
> After which, the car uses the selected
tolerance 5 km/h (4 mph) as long as
signs passed are showing 70 km/h
(43 mph).
> GREY button indication – ASL is
switched off and SL is activated
instead.
The tolerance is followed until a road sign with
a lower or higher speed is passed - then the
car follows the new signed speed limit instead
and the tolerance is deleted from the memory.
WARNING
After switching from ASL to SL the car will
no longer follow the signed speed limit but
only the stored maximum speed.
Related information
The maximum selectable tolerance is
+/- 10 km/h (5 mph).

Limitations for automatic speed
limiter
Automatic speed limitation (ASL47) takes
place using speed information from the Road
Sign Information function* (RSI48) – not from
the speed limit road signs that the car
passes.
Cruise control
The cruise control (CC49) helps the driver
maintain an even speed, which can result in
more relaxed driving on motorways and long,
straight roads in regular traffic flows.
In cars equipped with adaptive cruise con-
trol* (ACC50), it is possible to switch
between cruise control and adaptive cruise
control.
If road sign information cannot interpret and
provide speed information to the driver sup-
port systems, the automatic speed limiter is
set in standby mode and changes to normal
speed limiter. In such cases the driver must
intervene and brake to a suitable speed.
The automatic speed limiter will be reactivated
when road sign information can once again
interpret and provide speed information.
