Changing the tolerance for the

automatic speed limiter

The Automatic Speed Limiter function
(ASL

29

) 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).

 (RSI

31

) – 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 sets
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.

WARNING

•

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.

•

•

Driver support functions are not a sub-
stitute for the driver's attention and
judgement. The driver is always
responsible for ensuring the car is
driven in a safe manner, at the appro-
priate speed, with an appropriate dis-
tance to other vehicles, and in accord-
ance with current traffic rules and reg-
ulations.

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.

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

The cruise control is deactivated and set in
standby mode if any of the following occurs:

•

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

Automatic standby mode may occur if:

•

wheels lose traction

•

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

*

37

The adaptive cruise control (ACC

38

) helps the

driver to maintain an even speed combined
with a pre-selected time interval to the vehi-
cle 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 camera and radar unit measures the distance to

the vehicle ahead.

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.

When the road is clear again the car returns to
the selected speed.

If the cornering support

*

 function is activated,

this may also affect the speed of the car.

WARNING

•

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.

•

•

Driver support functions are not a sub-
stitute for the driver's attention and
judgement. The driver is always
responsible for ensuring the car is
driven in a safe manner, at the appro-
priate speed, with an appropriate dis-
tance to other vehicles, and in accord-
ance with current traffic rules and reg-
ulations.

Adaptive Cruise Control regulates the speed
with acceleration and braking. It is normal for
the brakes to emit a low sound when they are
being used to adjust the speed.

The adaptive cruise control aims to control the
speed in a smooth way. 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.

The adaptive cruise control aims to follow the
vehicle ahead in the same lane at a time inter-
val 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.

IMPORTANT

Maintenance of driver support components
must only be performed at a workshop –
an authorised Volvo workshop is recom-
mended.

This function can be either standard or optional, depending on market.

take place due to driver intervention or auto-
matically.

Standby mode means that the function is
selected in the driver display but not activated.
Adaptive cruise control does not then regulate
the speed or distance to the vehicle in front.

Standby mode on driver intervention

The adaptive cruise control is deactivated and
set in standby mode if any of the following
occurs:

•

The foot brake is used.

•

The gear selector is moved to 

N

 position.

•

The driver maintains a speed higher than
the stored speed for longer than 1 minute.

•

The clutch pedal is depressed for approx. 1
minute - applies to cars with manual gear-
box.

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.

WARNING

•

With the adaptive cruise control is in
standby mode, the driver must inter-
vene and regulate both speed and dis-
tance to the vehicle ahead.

•

When the adaptive cruise control is in
standby mode and the car comes too
close to a vehicle ahead, the driver may
be warned of the short distance by the
Distance Warning

*

 function instead.

Automatic standby mode

Adaptive cruise control is dependent on other
systems, e.g. stability control/anti-skid ESC

47

.

If any of these other systems stops working,
adaptive cruise control is deactivated auto-
matically.

WARNING

With automatic standby mode, the driver is

warned via an acoustic signal and a mes-

sage on the driver display.

•

The driver must then regulate the car's
speed, apply the brakes as needed and
maintain a safe distance to other vehi-
cles.

Automatic standby mode may occur if:

•

the speed is below 5 km/h ((3 mph)) and
ACC is uncertain whether the vehicle
ahead is a stationary vehicle or an object,
such as a speed bump.

•

the speed is below 5 km/h ((3 mph)) and
the vehicle ahead turns off so that ACC no
longer has a vehicle to follow.

•

speed is reduced to below 30 km/h
(20 mph) - only applies to cars with man-
ual gearbox.

•

the driver opens the door.

•

the driver takes off the seatbelt.

•

Steep roads and/or heavy load

Bear in mind that the adaptive cruise control is
primarily intended for use when driving on
level road surfaces. The function may have dif-
ficulty in keeping the correct distance from the
vehicle ahead when driving on steep downhill
slopes - in which case, be extra attentive and
ready to brake.

Do not use adaptive cruise control if the car
has a heavy load or a trailer is connected to
the car.

Miscellaneous

Off Road

 cannot be selected

when the adaptive cruise control is activated.

WARNING

•

This is not a collision avoidance sys-
tem. The driver is always responsible
and must intervene if the system does
not detect a vehicle ahead.

•

The function does not brake for
humans or animals, and not for small
vehicles such as bicycles and motorcy-
cles. Nor for low trailers, oncoming,
slow or stationary vehicles and objects.

•

Do not use the function in demanding
situations, such as in city traffic, at
junctions, on slippery surfaces, with a
lot of water or slush on the road, in
heavy rain/snow, in poor visibility, on
winding roads or on slip roads.

NOTE

This function uses the car's camera and

Pilot Assist

*

56

Pilot Assist can help the driver to drive the
car between the lane's side markings using
steering assistance as well as to maintain an
even speed, combined with a preselected
time interval to the vehicle ahead.

How Pilot Assist works

The Pilot Assist function is primarily intended
for use on motorways and similar major roads
where it can contribute to more comfortable
driving and a more relaxed driving experience.

The camera and radar unit measures the distance to

the vehicle ahead and detects side markings.

Camera and radar unit

Distance readers

Readers, side markings

The driver selects the desired speed and a
time interval to the vehicle ahead. Pilot Assist
scans the distance to the vehicle ahead and
the lane's side markings on the road surface
using the camera and radar unit. The preset
time interval is maintained with automatic
speed adjustment whilst the steering assis-
tance helps to position the car in the lane.

If the cornering support

*

 function is activated,

this may also affect the speed of the car.

Pilot Assist steering assistance takes into
account the speed of the preceding car and
the lane markings. The driver can at any time
ignore the Pilot Assist steering recommenda-
tion and steer in another direction, e.g. to
change lane or avoid an obstruction on the
road.

If Pilot Assist cannot interpret the lane unam-
biguously, e.g. if the camera and radar unit
