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 See manual message is dis-
played. 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
* Option/accessory, for more information, see Introduction.155
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 the Adap-
tive cruise control.
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 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 with large differ-
ences 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 160.
The adaptive cruise control can be activated to
follow another vehicle at speeds from
30 km/h
2 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 173) 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. It may have difficultly 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 atten-
tive and ready to slow down.
2Queue Assistant (in cars with automatic gearbox) can operate in the range of 0-200 km/h, see page 159.

Keypad without Speed limiter*To temporarily disengage Cruise control and
set it in standby mode:
•Press the steering wheel button .
Standby mode due to driver interventionCruise control is temporarily disengaged and
set in standby mode if:
•the foot brake is used
•the clutch pedal is depressed for longer
than 1 minute6
•the gear selector is moved to N position
(automatic gearbox)
•the driver maintains a speed higher than
the set speed for longer than 1 minute.
The driver must then regulate the speed.
A temporary increase in speed with the accel-
erator pedal, e.g. during overtaking, does not
affect the cruise control setting - the car returns
to the last stored speed when the accelerator
pedal is released.
Automatic standby modeThe Adaptive cruise control is dependent on
other systems, e.g.. DSTC (see page 146). Ifany of these systems stop working then cruise
control is automatically deactivated.
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/h7
•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 .
Overtaking another vehicleWhen the car is following another vehicle and
the driver indicates an imminent overtake with
the direction indicator
8, the Cruise control
helps to briefly accelerate the car towards the
vehicle in front.
The function is active at speeds
above 70 km/h.
WARNING
Be aware that this function can be activated
in more situations other than during over-
taking, e.g. when a direction indicator is
used to indicate a change of lane or exit to
another road - the car will then accelerate
briefly.
Deactivate
Keypad with Speed limiter
Adaptive cruise control is deactivated with the

160* Option/accessory, for more information, see Introduction.
WARNING
When the cruise control is following another
vehicle at speeds in excess of 30 km/h and
the target is changed from a moving vehicle
to a stationary vehicle, the cruise control will
ignore the stationary vehicle and instead
select the stored speed.
•The driver must intervene him/herself
and brake.
Automatic standby mode with change of
target
Cruise control is disengaged and set in
standby mode:
•when the speed is below 5 km/h and cruise
control is not sure whether the target
object is a stationary vehicle or some other
object, e.g. a speed bump.
•when the speed is below 5 km/h and the
vehicle in front turns off so the cruise con-
trol no longer has a vehicle to follow.
Termination of automatic braking at a
standstill
In certain situations Queue Assist automati-
cally interrupts braking when stationary. This
means that the brakes are released and the car
may start to roll - the driver must therefore
intervene and brake the car himself/herself in
order to maintain its position.Queue Assist releases the foot brake and sets
cruise control in standby mode in the following
situations:
•the driver puts his/her foot on the brake
pedal
•the parking brake is applied
•the gear selector is moved to P, N or R
position
•the driver sets the cruise control in standby
mode.
Automatic activation parking brakeIn some situations Queue Assist applies the
parking brake in order to keep the car station-
ary.
This takes place if:
•the driver opens the door or takes off his/
her seatbelt
•DSTC is changed from Normal to Sport
mode
•Queue Assist has held the car stationary
for more than 4 minutes
•the engine is switched off
•the brakes have overheated.
The radar sensor and its limitations
The radar sensor is used - apart from by Adap-
tive cruise control - by the following functions
as well:
•Collision Warning with Auto Brake, see
page 173
•Distance Warning, see page 165.
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.
Read the whole of this section for informa-
tion on the limitations of the adaptive cruise
control. The driver must be familiar with this
information 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.

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 area in front of the radar sensor
clean - see "Maintenance" on page 176.
•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.

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.
This means that in addition to the Adaptive
Cruise Control, Distance Warning and CollisionWarning 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.
Water or snow from the road surface swirls up and blocks the radar sig-
nals.No action. Sometimes the radar does not work on a very wet or snowy
road surface.
The radar surface has been cleaned but the message remains.Wait. It could take several minutes for the radar to sense that it is no
longer blocked.

City Safety™
04
168* Option/accessory, for more information, see Introduction.
General
City Safety™ is a function for helping the driver
to avoid a collision when driving in queues,
amongst other things, when changes in the
traffic ahead, combined with a lapse in atten-
tion, could lead to an incident.
The function is active at speeds
under50 km/h and it helps the driver by auto-
matically braking the car in the event of immi-
nent risk of collision with vehicles in front,
should the driver not react in time by braking
and/or steering away.
City Safety™ is activated in situations where
the driver should have started braking earlier,
which is why it cannot help the driver in every
situation.
City Safety™ is designed to be activated as
late as possible in order to avoid unnecessary
intervention.
City Safety™ must not be used as an excuse
for the driver to change his/her driving style. If
the driver solely relies on City Safety™ to do
the braking, there will be a collision sooner or
later.
The driver or passengers normally only notice
City Safety™ if a situation arises where the car
is extremely close to being in a collision.If the car is also equipped with a Collision
Warning function with Auto Brake*, these two
systems complement each other. For more
information on Collision Warning function with
Auto Brake, see page 173.
IMPORTANT
Maintenance and replacement of City
Safety™ components must only be per-
formed by a workshop - an authorised Volvo
workshop is recommended.
WARNING
City Safety™ does not engage in all driving
situations or traffic, weather or road condi-
tions.
City Safety™ does not react to vehicles
driving in a different direction from the car,
to small vehicles, motorcycles and bicycles
or to humans and animals.
City Safety™ can prevent collision at a
speed difference of less than 15 km/h - at a
higher speed difference, it is only possible
to reduce collision speed. In order to obtain
full brake function, the driver must depress
the brake pedal.
Never wait for City Safety™ to engage. The
driver always bears responsibility for main-
taining the proper distance and speed.
Function
Laser sensor transmitter and receiver window1.
City Safety™ detects the traffic in front of the
car with a laser sensor fitted in the top edge of
the windscreen. If there is an imminent risk of
collision, City Safety™ will automatically brake
the car, which may be experienced as sudden
braking.
If the speed difference is 4-15 km/h in relation
to the vehicle in front then City Safety™ can
completely prevent a collision.
City Safety™ activates a short, sharp braking
and stops the car in normal circumstances, just
behind the vehicle in front. For most drivers this
is well outside normal driving style and may be
experienced as being uncomfortable.
1NOTE: The illustration is schematic - details may vary depending on car model.

City Safety™

169
If the difference in speed between the vehicles
is greater than 15 km/h then City Safety™ may
not prevent the collision on its own. To obtain
full brake force, the driver must depress the
brake pedal. This could then make it possible
to prevent a collision, even at speed differen-
ces above 15 km/h.
When the function is activated and brakes, the
instrument panel display shows a message to
the effect that the function is/has been active.
NOTE
The brake lights come on when City
Safety™ brakes the car.
Operation
NOTE
The City Safety™ function is always ena-
bled after the engine has been started via
key position I and II (see page 78 on key
positions).
On and OffIn certain situations, it may advisable to disable
City Safety™, e.g. where leafy branches could
sweep over the bonnet and/or windscreen.
After starting the engine City Safety™ can be
deactivated as follows:
•Using MY CAR on the centre console dis-
play screen with its menu system, search
and locate Settings
Car settings
Driver support systemsCity Safety.
Select the
Off option. For more information
on the menu system MY CAR, see
page 202.
However, the function will be enabled the
next time the engine is started, regardless
of whether the system was enabled or dis-
abled when the engine was switched off.
WARNING
The laser sensor also transmits laser light
when City Safety™ is disabled manually.
To enable City Safety™ again:
•Follow the same procedure as for disa-
bling, but select the On option.
Limitations
The sensor in City Safety™ is designed to
detect cars and other large vehicles in front of
the car irrespective of whether it is day or night.
However, the sensor has limitations and has
poorer functionality - or none at all - in e.g.
heavy snowfall or rain, dense fog, dust storms
or snow flurries. Mist, dirt, ice or snow on the
windscreen may disrupt the function.Low-hanging objects, e.g. a flag/pennant for
projecting load, or accessories such as auxili-
ary lamps and bull bars that are higher than the
bonnet limit the function.
The laser light from the sensor in City
Safety™ measures how the light is reflected.
The sensor cannot detect objects with low
reflection capacity. The rear sections of the
vehicle generally reflect the light sufficiently
thanks to the number plate and rear light reflec-
tors.
On slippery road surfaces the braking distance
is extended, which may reduce the capacity of
City Safety™ to avoid a collision. In such sit-
uations the ABS and DSTC systems will pro-
vide best possible braking force with main-
tained stability.
When your own car is reversing, City Safety™
is temporarily deactivated.
City Safety™ is not activated at low speeds -
under 4 km/h, which is why the system does
not intervene in situations where a vehicle in
front is being approached very slowly, e.g.
when parking.
Driver commands are always prioritised, which
is why City Safety™ does not intervene in sit-
uations where the driver is steering or acceler-
ating in a clear manner, even if a collision is
unavoidable.
