Limitations of Road Sign
Information
*
The Road Sign Information (RSI
32
) 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
•
Fully/partially obscured or poorly posi-
tioned signs
•
Signs completely or partly covered with
frost, snow and/or dirt
•
Digital road maps
33
are out-of-date, inac-
curate or have no speed information
34
In certain markets, the Road Sign Informa-
tion function
*
is only available in combina-
tion with Sensus Navigation
*
.
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.
This function uses the car's camera and
radar units, which have certain general lim-
itations.

Speed limiter
A speed limiter (SL
35
) 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.

Temporary deactivation of speed
limiter
The speed limiter (SL
38
) can be temporarily
deactivated and set in standby mode.
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.
> 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.

Limitations for speed limiter
Speed limiter (SL
39
) has certain general limi-
tations.
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.
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).

Automatic speed limiter
The Automatic Speed Limiter (ASL
40
) func-
tion helps the driver to adapt the car's maxi-
mum speed to the speed shown on the road
signs.
The Speed Limiter function (SL
41
) can be
changed to Automatic Speed Limiter (ASL).
The automatic speed limiter uses speed infor-
mation from the Road Sign Information
*
(RSI
42
) function to automatically adapt the
car's maximum speed.
WARNING
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.

Changing the tolerance for the
automatic speed limiter
The Automatic Speed Limiter function
(ASL
46
) 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).
Buttons and symbols for the function
–
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).
> 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).
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.
The maximum selectable tolerance is
+/- 10 km/h (5 mph).

Limitations for automatic speed
limiter
Automatic speed limitation (ASL
47
) takes
place using speed information from the Road
Sign Information function
*
(RSI
48
) – not from
the speed limit road signs that the car
passes.
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.

Using engine braking instead of the
foot brake
With Cruise Control, speed is regulated with
less frequent application of the foot brake. On
a downhill gradient it may sometimes be
desirable to start moving a little faster and
limit the acceleration by engine braking. In this
case the driver can temporarily disable foot
brake application by Cruise Control.
To do so, proceed as follows:
–
Depress the accelerator pedal about half-
way down and release.
> Cruise Control will disengage its auto-
matic foot braking and then uses
engine braking only.

Standby mode for cruise control
Cruise control (CC
53
) can be deactivated and
set in standby mode. This can take place due
to driver intervention or automatically.
Standby mode means that the function is
selected in the driver display but not activated.
In this case, cruise control does not regulate
speed.
Standby mode on driver intervention
Cruise control is deactivated and set to
standby mode if any of the following occur:
•
The foot brake is used.
•
The gear selector is moved to
N
position.
•
The clutch pedal is held depressed for
longer than 1 minute.
•
The driver maintains a speed higher than
the stored speed for longer than 1 minute.
The driver must then control the speed him-
self/herself.
A temporary increase in speed with the accel-
erator pedal, e.g. during overtaking, does not
affect the setting - the car returns to the last
stored speed when the accelerator pedal is
released.
Automatic standby mode
Activation of automatic standby mode can be
due to one of the following:
•
The wheels are losing traction.
•
The engine speed is too low/high.
•
Brake temperature is too high.
•
Speed falls below 30 km/h (20 mph).
The driver must then control the speed him-
self/herself.

Adaptive cruise control
*
54
The adaptive cruise control (ACC
55
) can help
the driver to maintain a constant speed, com-
bined with a preset time interval to the vehi-
cle ahead.
The camera and radar unit measures the distance to
the vehicle ahead.
An adaptive cruise control can provide a more
relaxing driving experience on long journeys on
motorways and long straight main roads in
smooth traffic flows.
The driver selects the desired speed and a
time interval to the vehicle ahead. If the cam-
era and radar unit detects a slower vehicle in
front of the car, the speed is adapted automat-
ically via the preset time interval to the vehicle.

306
When the road is clear again the car returns to
the selected speed.
The adaptive cruise control aims to:
•
regulate the speed smoothly. In situations
that demand sudden braking the driver
must brake himself/herself. This applies in
cases of large speed differences or if the
vehicle in front brakes suddenly. Due to
the limitations of the radar unit, braking
may come unexpectedly or not at all.
•
follow the vehicle ahead in the same lane
at a time interval set by the driver. If the
radar unit cannot see any vehicle in front
then the car will instead maintain the
speed set and stored by the driver. This
also takes place if the speed of the vehicle
ahead increases and exceeds the stored
speed.

must only be performed at a workshop –
an authorised Volvo workshop is recom-
mended.
