Driving after a collision
If the car is involved in a collision, the textSafety mode See manual may appear on the
information display. This means that the car
has reduced functionality. Safety mode is a
protective state that is enforced when the col-
lision may have damaged any of the car's vital
functions, such as the fuel lines, sensors for
one of the safety systems, or the brake system.
Attempting to start the carFirst, check that no fuel is leaking from the car.
There must be no smell of fuel either.
If everything seems normal and you have
checked for indications of fuel leakage, you
may attempt to start the car.
Remove the remote control key and open the
driver's door. If a message is now shown to theeffect that the ignition is on, press the start
button. Then close the door and reinsert the
remote control key. The car's electronics will
now try to reset themselves to normal mode.
Then try to start the car.
If the message
Safety mode See manual is
still shown on the display then the car must not
be driven or towed, but a vehicle recovery serv-
ice used instead. Even if the car appears to be
driveable, hidden damage may make the car
impossible to control once moving.
Moving the car
If Normal mode is shown after Safety mode
See manual has been reset, the car can be
moved carefully out of a dangerous position.
Do not move the car further than necessary.
WARNING
Never attempt to repair your car or reset the
electronics yourself if the car has been in
safety mode. This could result in personal
injury or the car not functioning as normal.
Volvo recommends that you engage an
authorised Volvo workshop to check and
restore the car to normal status after
Safety
mode See manual has been displayed.
WARNING
Never, under any circumstances, attempt to
restart the car if it smells of fuel when the
Safety mode message is displayed. Leave
the car at once.
WARNING
If the car is in safety mode it must not be
towed. It must be transported from its loca-
tion. Volvo recommends that it is transpor-
ted to an authorised Volvo workshop.

Adaptive cruise control*
04
172* Option/accessory, for more information, see Introduction.
WARNING
Adaptive cruise control is not a collision
avoidance system. The driver must inter-
vene if the system does not detect a vehicle
in front.
The adaptive cruise control does not brake
for humans or animals, and not for small
vehicles such as bicycles and motorcycles.
Nor for oncoming, slow or stationary vehi-
cles and objects.
Do not use the adaptive cruise control, for
example, in city traffic, in dense 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.
The distance to the vehicle ahead is mainly
measured by a radar sensor. 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 by cruise con-
trol.
WARNING
The brake pedal moves when the cruise
control brakes. Do not rest your foot under
the brake pedal as it could become trapped.
The adaptive cruise control aims to follow the
vehicle ahead in the same lane at a time interval
set by the driver. If the radar sensor cannot see
any vehicle in front then the car will instead
maintain the cruise control's set speed. This
also happens if the speed of the vehicle in front
exceeds the cruise control's set speed.
The cruise control aims to control the speed in
a smooth way. In situations that demand sud-
den braking the driver must brake himself/her-
self. This applies with large differences in
speed, or if the vehicle in front brakes heavily.
Due to limitations in the radar sensor, braking
may come unexpectedly or not at all, see
page 177.
The adaptive cruise control can be activated to
follow another vehicle at speeds from
30 km/h
1 up to 200 km/h. If the speed falls
below 30 km/h or if the engine speed becomes
too low, the cruise control is set in standby
mode at which automatic braking ceases - the
driver must then take over himself/herself to
maintain a safe distance to the vehicle ahead.
Warning lamp - braking by driver
required
Adaptive cruise control has a braking capacity
that is equivalent to more than 40% of the car's
braking capacity.If the car needs to be braked more heavily than
cruise control capacity and the driver does not
brake, then the cruise control uses the collision
warning system's warning lamp and warning
sound (see page 189) to alert the driver that
immediate intervention is required.
NOTE
The warning lamp may be difficult to notice
in strong sunlight or when sunglasses are
being worn.
WARNING
Cruise control only warns of vehicles
detected by the radar sensor. Consequently
there may be no warning or it may be sub-
ject to a delay. Do not wait for a warning but
brake when it is necessary.
Steep roads and/or heavy loadBear in mind that the adaptive cruise control is
primarily intended for use when driving on level
road surfaces. The cruise control may have dif-
ficultly in keeping the correct distance from the
vehicle ahead when driving on steep roads,
with a heavy load or with a trailer - in which
case, be extra attentive and ready to slow
down.
1Cars with automatic gearbox ("Queue Assist") can operate in the range of 0-200 km/h, see page 175.

Automatic standby modeAdaptive cruise control is dependent on other
systems e.g. stability and traction control
(DSTC). If any of these systems stop working
then cruise control is automatically deacti-
vated.
In the event of automatic deactivation a signal
will sound and the message
Cruise control
Cancelled is shown in the display. The driver
must then intervene and adapt the speed and
distance to the vehicle ahead.
An automatic deactivation can be due to:
•engine speed is too low/high
•speed falls below 30 km/h5
•wheels lose traction
•brake temperature is high
•the radar sensor is covered e.g. by wet
snow or heavy rain (radar waves blocked).
Resume set speedCruise control in standby mode is re-activated
with one press on the steering wheel button
- the speed is then set to the last stored
speed.
NOTE
A significant increase in speed may arise
after the speed has been resumed with .
DeactivateThe cruise control is switched off with the
steering wheel button
. The set speed is
cleared and cannot be resumed with the
button.
Keypad without Speed limiterThe cruise control is switched off with the
steering wheel button
in standby mode or
with one long press in active mode. The set
speed is cleared and cannot be resumed with
the
button.
Queue Assist ACC and automatic
gearbox*
In cars with automatic gearbox the adaptive
cruise control has more functions than in cars
with manual gearbox.
Note that the lowest programmable speed for
the cruise control is 30 km/h - even though the
cruise control is capable of following another
vehicle down to a standstill, a lower speed
cannot be selected.The following functions are available:
Extended speed range
NOTE
In order to activate the cruise control the
driver's door must be closed and the driver
must be wearing the seatbelt.
•With the automatic gearbox the cruise con-
trol can follow another vehicle within the
range of 0-200 km/h - right down to sta-
tionary and up to 200 km/h.
NOTE
Activation of the cruise control below
30 km/h requires a vehicle in front within a
reasonable distance.
For shorter stops in connection with inching in
slow traffic or at traffic lights driving is auto-
matically resumed if the stops do not exceed
about 3 seconds - if it takes longer before the
car in front starts moving again then the cruise
control is set in standby mode. The driver must
then re-activate the cruise control in one of the
following ways:
•Press the steering wheel button .
5Does not apply to cars with automatic gearbox ("Queue Assist") - they manage right down to stationary.

* Option/accessory, for more information, see Introduction.177 The radar sensor and its limitations
Apart from the adaptive cruise control, the
radar sensor is also used by the Collision
Warning with Auto Brake function (see
page 188) and the Distance Alert function (see
page 181). The function of the radar sensor is
to detect cars or larger vehicles in the same
direction, in the same lane.
Modification of the radar sensor could result in
it being illegal to use.
WARNING
The driver must always be observant with
regard to the traffic conditions and intervene
when the adaptive cruise control is not
maintaining a suitable speed or suitable dis-
tance.
The adaptive cruise control cannot handle
all traffic, weather and road conditions.
The Function section and onwards informs
about limitations of which the driver should
be aware before using the adaptive cruise
control.
The driver always bears responsibility for
maintaining the correct distance and speed,
even when the adaptive cruise control is
being used.
WARNING
Accessories or other objects such as auxil-
iary lamps must not be installed in front of
the grille.
WARNING
Adaptive cruise control is not a collision
avoidance system. The driver must inter-
vene if the system does not detect a vehicle
in front.
The adaptive cruise control does not brake
for humans or animals, and not for small
vehicles such as bicycles and motorcycles.
Nor for oncoming, slow or stationary vehi-
cles and objects.
Do not use the adaptive cruise control, for
example, in city traffic, in dense 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.
The capacity of the radar sensor to detect vehi-
cles in front is reduced significantly:
•if the radar sensor becomes blocked and
cannot detect other vehicles e.g. in heavy
rain or slush, or if other objects have col-
lected in front of the radar sensor.
NOTE
Keep the surface in front of the radar sensor
clean.
•if the speed of vehicles in front is signifi-
cantly different from your own speed.
Examples where the cruise control does
not work optimally
The radar sensor has a limited field of vision. In
some situations another vehicle is not
detected, or the detection is made later than
expected.

The ACC cannot see small vehicles (Dark triangle:
ACC field of vision).
Sometimes the radar sensor is late at
detecting vehicles at close distances, e.g.
a vehicle that drives in between the car and
vehicles in front.
Small vehicles, such as motorcycles, or
vehicles not driving in the centre of the lane
can remain undetected.
In bends the radar sensor may detect the
wrong vehicle or lose a detected vehicle
from view.
Fault tracing and action
If the display shows the message Radar
blocked See manual this means that the
radar signals from the radar sensor are blocked
and that vehicles in front of the car could not
be detected.
In turn this means that the Adaptive Cruise
Control, Distance Alert and Collision Warning
with Auto Brake functions are not operating
either.The following table presents possible causes
for a message being shown along with the
appropriate action.
CauseAction
The radar surface in the grille is dirty or covered with ice or snow.Clean the radar surface in the grille from dirt, ice and snow.
Heavy rain or snow blocking the radar signals.No action. Sometimes the radar does not work during heavy rain or
snowfall.
