Road Sign Information (RSI)* -
operation
The Road Sign Information function (RSI
30
) reg-
isters and shows road signs in different ways
depending on the sign and the situation.
Example
31
of detected speed information.
When RSI has recorded a road sign with an
imposed speed, the combined instrument panel
displays the sign as a symbol.
An additional
31
sign, such as
"no overtaking", may be shown
together with the speed limit
symbol.
End of speed limit or motorway
When RSI detects an "indirect speed sign" that
means end of current speed limit - e.g. at end of
motorway - a symbol with the corresponding road
sign is shown in the combined instrument panel.
Examples of indirect speed sign
31
are:
End of all restrictions.
End of motorway.
The symbol in the combined instrument panel
extinguishes after 10-30 seconds and remains
extinguished until the next speed-related sign is
passed.
Changed speed limit
On passing a direct speed sign when the speed
limit changes, a symbol with the corresponding
road sign is shown in the combined instrument
panel.
Example of a direct speed
sign
31
.
The symbol in the combined instrument panel
extinguishes after approx. 5 minutes and remains
extinguished 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.

245
Additional signs
Examples of additional signs
31
.
Sometimes different speed limits are signposted
for the same road - an additional sign then indi-
cates the circumstances under which the differ-
ent speeds apply. The road section may be par-
ticularly 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.
The speed applicable on an exit
is indicated in certain markets
by means of an additional sign
containing an arrow.
Speed signs linked to this type
of additional sign are displayed
only if the driver is using the direction indicator.
Some speeds are applicable
only after e.g. a specific dis-
tance or at a certain time of
day. The driver's attention is
drawn to the situation by
means of a symbol for an addi-
tional sign under the symbol
showing speed.
A symbol for additional sign in
the form of an empty frame
under the combined instrument
panel's speed symbol
31
means
that RSI has detected an addi-
tional sign with supplementary
information for the current
speed limit.
Speed Alert On/Off
The
Speed Limit Warning
subfunction for RSI
is selectable - the driver can select On or Off.
The speed warning is given in
the form of the combined
instrument panel's symbol
31
for
maximum permitted speed
temporarily flashing when the
speed is exceeded by 5 km/h
(5 mph) or more.
Activate
Speed alert
as follows:
1. Search and locate the function in the menu
system MY CAR, see MY CAR (p. 113).
2. Highlight
Speed alert
by pressing the OK/
MENU button once and go back out with
EXIT.

Road Sign Information* (RSI) -
limitations
The Road Sign Information (RSI
32
) function may
have limitations in certain situations.
The camera sensor for RSI has limitations just
like the human eye. Find out more about this in
the section on the camera sensor limitations
(p. 235).
Signs which indirectly provide information on a
prevailing speed limit, e.g. name signs for towns/
districts, are not recorded by RSI.
Examples of factors that can reduce RSI are as
follows:
•
Faded signs
•
Signs positioned on bends
•
Rotated or damaged signs
•
Signs positioned high above the roadway
•
Fully/partially obscured or poorly positioned
signs
•
signs completely or partly covered with frost,
snow and/or dirt
•
digital road maps
33
are out-of-date, inaccu-
rate or have no speed information
34

Driver Alert System*
The Driver Alert System is intended to assist dri-
vers whose driving ability is deteriorating or who
are inadvertently leaving the lane they are driving
on.
The Driver Alert System consists of different
functions which can either be switched on at the
same time or individually:
•
Driver Alert Control - DAC (p. 248).
•
A switched-on function is set in standby mode
and is not activated automatically until speed
exceeds 65 km/h (40 mph).
The function is deactivated again when speed
decreases to below 60 km/h (37 mph).
The functions use a camera which is dependent
on the lane having side markings painted on
each side.
WARNING
Driver Alert System does not work in all situa-
tions but is designed merely as a supplemen-
tary aid.
The driver always bears ultimate responsibility
for ensuring that the vehicle is driven safely.

Driver Alert Control (DAC)*
DAC 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.
A camera detects the side markings painted on
the carriageway and compares the section of the
road with the driver's steering wheel movements.
The driver is alerted if the vehicle does not follow
the carriageway evenly.
In some cases driving ability is not affected
despite driver fatigue. In which case there may
not be any warning issued for the driver. For this
reason it is always important to stop and take a
break in the event of any signs of driver fatigue,
irrespective of whether or not DAC issues a
warning.
The function must not be used to extend a
period of driving. Always plan breaks at regu-
lar intervals, and make sure you are well
rested.
Limitation
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.
DAC is not intended for city traffic.
The camera sensor has certain limitations,

Driver Alert Control (DAC)* -
operation
Settings are made from the centre console dis-
play screen and its menu system.
On/Off
The Driver Alert function can be set in standby
mode via the menu system MY CAR (p. 113):
•
Checked box - function activated.
•
Unchecked box - the function is deactivated.
Function
Driver Alert is activated when speed exceeds
65 km/h (40 mph) and remains active as long as
the speed is above 60 km/h (37 mph).
If the vehicle is being driven erratically,
the driver is notified by an acoustic sig-
nal plus the text message (p. 249)
Driver Alert Time for a break
- the
linked symbol is illuminated in the combined
instrument panel at the same time. The warning
is repeated after a time if driving ability does not
improve.
The warning symbol can go off:
•
Press the left stalk switch OK button.
WARNING
An alarm should be taken very seriously, as a
sleepy driver is often not aware of his/her
own condition.
In the event of an alarm or a feeling of tired-
ness; stop the car in a safe manner as soon
as possible and rest.
Studies have shown that it is equally as dan-
gerous to drive while tired as it is under the
influence of alcohol.

Lane assistance*
Lane Keeping Aid is one of the functions in the
Driver Alert System - sometimes also referred to
as LKA (Lane Keeping Aid).
The function is intended for use on motorways
and similar major roads in order to reduce the
risk of the vehicle accidentally leaving its own
lane in certain situations.
A camera reads the painted side lines of the
road/lane. If the car is about to cross a side line
then Lane Keeping Aid will actively steer the car
back into the lane with a slight steering torque in
the steering wheel.
If the car reaches or crosses a side line then
Lane Keeping Aid will also alert the driver with
vibration in the steering wheel.
WARNING
LKA is merely a driver's aid and does not
engage in all driving situations or traffic,
weather or road conditions.
The driver always bears ultimate responsibility
for ensuring that the vehicle is driven safely
and that applicable laws and road traffic regu-
lations are followed.

Certain settings can be made for the Lane Keep-
ing Aid (Lane Keeping Aid) function.
Off & On
Lane Keeping Aid is active within the speed
range 65-200 km/h (40-125 mph) on roads with
clearly visible side lines. The function is temporar-
ily deactivated on narrow roads with less than 2.6
metres between the lane side lines.
Press the centre console's button to activate or
deactivate the function. The button's lamp illumi-
nates when the function is switched on.
Some combinations of the selected equipment
leave no vacant space for an On/Off button in
the centre console - in which case, the function
is instead operated in the car's menu system MY
CAR (p. 113). Here, proceed as follows:

Active steering
Lane Keeping Aid strives to keep the car within
the side lines for the lane.
LKA intervenes and steers away.
If the car approaches the left or right side line of
the lane and the direction indicator is not acti-
vated, the car is steered back into the lane.
Warning with vibration in the steering
wheel
LKA steers and alerts with steering wheel vibration
35
.
If the car crosses a side line then Lane Keeping
Aid will alert the driver with vibration in the steer-
ing wheel
36
. This occurs regardless of whether
the car is actively steered back by applying a
slight steering torque.
Dynamic cornering
LKA does not engage in sharp inside curves.
In certain cases Lane assistance will allow the
car to cross lane lines without engaging active
steering or activating a warning. Using an adja-
cent lane for cutting a corner when there is a
clear line of vision is an example of this.

Lane Keeping Aid - operation
Lane Keeping Aid is complemented in the com-
bined instrument panel with intuitive graphics in
different situations. Here are some examples:
LKA is temporarily deactivated for as long as
the direction indicator is switched on.
LKA "sees" the following side lines.
If Lane Keeping Aid is active and detects/"sees"
the side lines, the LKA symbol indicates this with
WHITE lines.
•
GREY side line - Lane Keeping Aid does not
see a line on that side of the car.
LKA engages on the right side.
Lane Keeping Aid intervenes and steers away
from the side line - this is indicated with:
•
RED line for the side in question.

•
Lane Keeping Aid - limitations
Lane Keeping Aid's camera sensor has limita-
tions in a similar way to the human eye.
For more information, see Collision warning sys-
tem
* - camera sensor limitations (p. 235) and
In certain demanding situations Lane assis-
tance may have difficulty assisting the driver
in the right way - in which case it is recom-
mended to deactivate the function.
Examples of such situations may be:
•
roadworks
•
winter road conditions
•
poor road surface
•
very sporty driving style
•
poor weather with reduced visibility.
Hands on the steering wheel
In order for Lane Keeping Aid to operate, the
driver must have his/her hands on the steering
wheel. LKA continually monitors this. If hands are
not detected on the steering wheel then a text
message is shown, prompting the driver to
actively steer the car.
If the driver does not follow the request to begin
steering then Lane Keeping Aid goes into

Park Assist*
Parking assistance is used as an aid to parking.
An acoustic signal as well as symbols on the
centre console's display screen indicate the dis-
tance to the detected obstacle.
Parking assistance sound level can be adjusted
during the ongoing acoustic signal using the cen-
tre console's VOL knob or in the car's menu sys-
tem MY CAR, see MY CAR (p. 113).
Parking assistance is available in two variants:
•
Rear only
•
Both front and rear.
Since a towbar is configured with the car's
electrical system, towbar protrusion is
included when the function measures the dis-
tance to an object behind the car.
WARNING
•
Parking assistance does not relinquish
the driver's own responsibility during
parking.
•
The sensors have blind spots where
obstacles cannot be detected.
•
Be aware of e.g. people and animals near
the car.

Display screen view - showing an obstacle left front and
right rear.
Marked sectors show which of the four sensor(s)
detected an obstacle. The closer to the car sym-
bol a selected sector box is, the shorter the dis-
tance between the car and a detected obstacle.
The frequency of the signal increases the shorter
the distance to an obstacle, in front of or behind
the car. Other sound from the audio system is
muted automatically.
When the distance is within 30 cm the tone is
constant and the active sensor's field nearest the
car is filled in. If the detected obstacle is within
the distance for the constant tone both behind
and in front of the car, then the tone sounds
alternately from the loudspeakers.
Objects e.g. chains, thin glossy poles or low
barriers may be in the "signal shadow" and
are then temporarily not detected by the sen-
sors - the pulsating tone may then unexpect-
edly stop instead of changing over to the
expected constant tone.
The sensors cannot detect high objects, such
as projecting loading docks.
•
In such situations, pay extra attention and
manoeuvre/reposition the car particularly
slowly or stop the current parking
manoeuvre - there may be a high risk of
damage to vehicles or other objects since
information from the sensors is not
always reliable in such situations.

Park assist syst* - backward
Parking assistance is used as an aid to parking.
An acoustic signal as well as symbols on the
centre console's display screen indicate the dis-
tance to the detected obstacle.
The distance covered to the rear of the car is
about 1.5 metres. The acoustic signal for obsta-
cles behind comes from one of the rear loud-
speakers.
Rear parking assistance is activated when
reverse gear is engaged.
When reversing with e.g. a trailer on the towbar,
rear parking assistance is switched off automati-
cally - otherwise the sensors would react to the
trailer.
DRIVER SUPPORT
* Option/accessory.
257
When reversing with e.g. a trailer or bike car-
rier on the towbar - without Volvo genuine
trailer wiring - parking assistance may need to
be switched off manually in order that the
sensors do not react to them.

Park assist syst* - forward
Parking assistance is used as an aid to parking.
An acoustic signal as well as symbols on the
centre console's screen indicate distance to
detected obstacles.
The parking assistance system is automatically
activated when the engine is started - the
switch's On/Off lamp is illuminated. If parking
assistance is switched off with the button, the
lamp goes out.
The distance covered in front of the car is about
0.8 metres. The acoustic signal for obstacles in
front comes from one of the front loudspeakers.
Forward parking assistance is active up to
10 km/h (6 mph). If the Parking Assistance Sys-
tem is deactivated because the car is moving too
quickly - 11 km/h (7 mph) or above - the func-
tion is reactivated when the speed falls below 10
km/h (6 mph).
When auxiliary lamps are fitted: Remember
that these must not obscure the sensors - the
auxiliary lamps may then be perceived as an
obstacle.

Park assist syst* - fault indication
Parking assistance is used as an aid to parking.
An acoustic signal as well as symbols on the
centre console's display screen indicate the dis-
tance to the detected obstacle.
If the combined instrument panel's
information symbol illuminates with
constant glow and the text message
Park Assist System Service required
is
shown then parking assistance is disengaged.
Under some circumstances, the parking sen-
sors can give false warning signals due to
external sound sources which emit the same
ultrasound frequencies as those with which
the system works.
Examples of such sources include horns, wet
tyres on asphalt, pneumatic brakes and
exhaust noises from motorcycles etc.
