Sign display with Road Sign

Information

The Road Sign Information function (RSI

72

) reg-

isters and shows road signs in different ways
depending on the sign and the situation.

Example

73

 of detected speed information.

When RSI detects a road sign with an imposed
speed limit, the driver display shows the sign as a
symbol plus an indication in red on the speedom-
eter.

An additional

73

 sign, such as

"no overtaking", may be shown
together with the speed limit
symbol.

If the driver enters a road
marked with a no-entry sign at
the roadside, the symbol for
this sign

73

 flashes on and off

on the driver display as a warn-
ing.

If the car is equipped with Sensus Navigation

*

then information from the map is also used to
determine whether the car is being driven in the
wrong direction.

The driver can also get an acoustic warning when
driving towards a no-entry entrance if the 

Audio

Warning

 function is activated - see the heading

"Activating/deactivating the acoustic warning" in
the section "Activating/deactivating Road Sign
Information".

Speed limit or end of motorway

When RSI detects an "indirect speed limit sign"
stating the end of the current speed limit - e.g. at
the end of a motorway - a symbol appears with
the corresponding road sign in the driver's dis-
play.

Example of indirect speed limit sign

73

:

End of all restrictions.

End of motorway.

The driver display symbol extinguishes after
10-30 seconds and remains so until the next
speed related sign is passed.

Changed speed limit

When passing a direct speed limit sign when a
speed limit changes, a symbol with the corres-
ponding road sign appears in the driver's display.

DRIVER SUPPORT

* Option/accessory.

364

The driver display symbol extinguishes after
about 5 minutes and remains so until the next
speed related sign is passed.

Sensus Navigation

If the car is equipped with Sensus Navigation,
speed information is read from the navigation
unit in the following cases:

On detection of signs that indirectly indicate
a speed limit, such as motorway, dual car-
riageway and city limit signs.

If a previously detected speed sign is
assumed not to apply any longer, but no new
sign has been detected.

NOTE

If a downloaded third-party app is used for
navigation then there is no support for speed-
related information.

Additional signs

Examples of additional signs

73

.

Sometimes different speed limits are signed for
the same road - an additional sign then indicates
the circumstances under which the different
speeds apply. The road section may be particu-
larly susceptible to accidents in rain and/or fog,
for example.

An additional sign relating to rain is displayed
only if the windscreen wipers are in use.

If the car has a trailer attached and you pass a
speed sign with the additional sign “trailer”, the
indicated speed will appear on the driver display.

Some speed limits only apply
after a certain distance or at a
certain time of day. The driver's
attention is drawn to this fact
by means of a symbol for an
additional sign below the speed
symbol. The additional symbol

in the driver display will show either “DIST” or
“TIME”.

A symbol for additional sign in
the form of an empty frame
under the driver display's speed
symbol

73

 means that the RSI

has detected an additional sign
with supplementary information
for the current speed limit.

Sign for "School" and "Children at play"

If the warning sign

73

 for

"School" or "Children at play"
is included in the satellite navi-
gator's map data

74

, the driver

display shows a sign of this
type.

Driver Alert Control

The Driver Alert Control (DAC) function is
intended to attract the driver's attention when he
or she starts to drive less consistently, e.g. if the
driver becomes distracted or starts to fall asleep.

The objective for DAC is to detect slowly deterio-
rating driving ability and it is primarily intended for
major roads. The function is not intended for city
traffic.

The function is activated when speed exceeds
65 km/h (40 mph) and remains active as long as
the speed is over 60 km/h (37 mph).

A camera detects the edge markings painted on
the carriageway and compares the alignment of
the road with the driver’s steering wheel move-
ments.

When driving behaviour starts
to become inconsistent, the
driver is alerted by this symbol
in the driver display, together
with the text message 

Time

for a break soon?

.

If driving behaviour does not improve but
becomes noticeably inconsistent, the driver is
alerted by the same symbol in the driver display,
combined with an acoustic signal and the text
message 

Time to take a break

.

If the 

Rest Stop Guidance

 function is activated

in Sensus Navigation

*, suggestions for a suitable

location for a break are also shown with the

Time to take a break

 warning.

The warnings are repeated after a time if driving
behaviour has not improved.

WARNING

The Driver Alert Control function is sup-
plementary driver support intended to
facilitate driving and make it safer – it
cannot handle all situations in all traffic,
weather and road conditions.

Driver Alert Control should not be used to
extend a period of driving. The driver
should instead plan for breaks at regular
intervals and make sure they are well
rested.

Driver Alert Control is not a substitute for
the driver's attention and judgement. The
driver is always responsible for ensuring
the car is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

WARNING

An alarm from Driver Alert Control should be

taken very seriously, as a sleepy driver is often

not aware of his/her own condition.
If the alarm sounds or you feel fatigued:

Stop the car safely as soon as possible
and rest.

Studies have shown that it is just as danger-

ous to drive while tired as it is to drive under

the influence of alcohol or other stimulants.

Limitations of Driver Alert Control

The Driver Alert Control (DAC) function may
have limitations in certain situations.

In some cases the system may issue a warning
despite driving ability not deteriorating, for exam-
ple:

in strong side winds

on rutted road surfaces.

WARNING

In some cases, driving behaviour is not affec-

ted despite driver fatigue – e.g. when using

the Pilot Assist function – resulting in the

driver not getting a warning from DAC.
It is therefore important to always stop and

take a break at the slightest feeling of fatigue,

whether the DAC function ha given a warning

or not.

NOTE

The function uses the car's camera unit,
which has some general limitations, see the
"Limitations for camera unit" section.

Lane Keeping Aid

The function of the Lane Keeping Aid (LKA

82

) is

to help the driver to reduce the risk of the car
accidentally leaving its own lane on motorways
and similar major routes.

Lane Keeping Aid steers the car back into its
lane and/or alerts the driver with vibrations in the
steering wheel.

Lane Keeping Aid is active within the speed
range 65-200 km/h (40-125 mph) on roads with
clearly visible side lines.

On narrow roads the function may be unavailable,
in which case it goes into standby mode. The
function becomes available again when the road
is wide enough.

A camera reads the side lines of the road/lane.

Lane assistance steers the car back into its lane.

Lane assistance warns with steering wheel vibrations

83

.

Depending on settings, lane assistance acts in
accordance with the following:

Assist

84

 activated: When the car is

approaching a lane line, LKA will actively
steer the car back into its lane by applying a
slight torque to the steering wheel.

Warning

84

 activated: If the car is about to

cross a lane line, the driver is warned by
means of vibrations in the steering wheel.

NOTE

When a direction indicator is switched on,
there are no steering corrections or alerts
from Lane assistance.

WARNING

The Lane Keeping Aid function is supple-
mentary driver support intended to
improve driving safety – it cannot handle
all situations in all traffic, weather and
road conditions.

The function is not a substitute for the
driver's attention and judgement. The
driver is always responsible for ensuring
the car is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

Steering assistance

In order for LKA to function, the driver’s hands
must be on the steering wheel. The system moni-
tors this continuously.

If the driver does not keep
his/her hands on the steering
wheel, the driver display shows
this symbol and the following
message, to prompt the driver
to actively steer the car:

Lane Keeping Aid

 

Apply steering

82

Lane Keeping Aid

83

The steering wheel vibration varies - the longer the car remains outside the lane lines, the longer the vibration.

84

See the heading "Assistance alternatives for LKA" in the section "Activating/Deactivating Lane Keeping Aid".

DRIVER SUPPORT

* Option/accessory.

372

If the driver does not then start to steer, the sym-
bol is shown again, combined with a warning
sound and this message:

Lane Keeping Aid

 

Standby until steering

applied

If the driver then still does not follow the prompt
to start steering, LKA is set in standby mode -
the function will then be unavailable until the
driver starts to steer the car again.

Lane assistance does not intervene

Lane assistance does not engage on sharp inside

curves.

In some situations, lane assistance allows lane
lines to be crossed without intervening with either
steering assistance or a warning - e.g. when
using the direction indicators or cutting bends.

Limitations

In certain demanding conditions Lane assistance
may have difficulty helping the driver correctly. In
such cases it is recommended to switch off this
function.

Examples of such conditions are:

road works

winter road conditions

poor road surface

a very “sporty” driving style

poor weather with reduced visibility

sharp edges or lines other than the lane lines

roads with unclear or non-existent line mark-
ings.

NOTE

The function uses the car's camera unit,
which has some general limitations, see the
"Limitations for camera unit" section.

Steering assistance upon risk of

lane departure

The subfunction's task is to help the driver
reduce the risk of the car accidentally leaving the
road by actively steering the car back onto the
road.

The function is active within the speed range
65-140 km/h (40-87 mph) on roads with clearly
visible lane markings/lines.

A camera scans the edges of the road and the
painted side markings. If the car is about to leave
the side of the road, the car is steered back onto
the road and if the steering intervention is not
enough to avoid run-off, the brakes are also acti-
vated.

The function does not intervene however with
steering assistance or braking if the direction
indicators are used and if the function detects
that the driver is actively driving the car, activation
of the function will be delayed.

After automatic engagement, the driver indicates
that this has occurred via a text message:

Collision avoidance
assistance

Automatic intervention

Level of steering assistance

The function has two activation levels:

Steering assistance only

Steering assistance with brake intervention

Steering assistance only

Intervention with steering assistance.

Steering assistance with brake intervention

Intervention with steering assistance and braking.

Brake intervention helps in situations where
steering assistance alone is not sufficient. The
brake force is adapted automatically depending
on the situation at the time of road run-off.
