The remote key is used to lock and unlock doors
and the tailgate. The remote key must be in the
vehicle in order to start the engine. Remote control key, on left, and button-less key ((Key
Tag)*), on right.
The remote key is not physically used to start the
ignition because the vehicle is standard-equipped
with keyless start (Passive Start). To start the
vehicle, the key must be in the front section of
the passenger compartment, e.g. in the driver's
pocket or in a cup holder in the tunnel console.

3 - Auto-brake
The automatic braking function is activated at the
last moment.
If the driver has not taken evasive action by this
stage and a collision is imminent, the automatic
braking function will be triggered. This occurs
whether or not the driver is pressing the brake
pedal. Full braking force will be applied to reduce
the speed at impact or reduced braking effect will
be applied if this is sufficient to avoid the colli-
sion.
The seat belt tensioners may be activated along
with the automatic braking function. See "Seat
belt tensioners" for more information.
In certain situations, auto-braking may begin with
a limited braking force before applying full brak-
ing force.
If City Safety has prevented a collision, the vehi-
cle will be kept at a standstill until the driver
takes action. If the vehicle has slowed to avoid
colliding with a slower-moving vehicle ahead, your
speed will be reduced to that vehicle's speed.
Auto-braking can always be cancelled if the
driver presses hard on the accelerator pedal.
NOTE
When City Safety activates the brakes, the
brake lights come on. When City Safety applies the brakes, a text mes-
sage will appear in the instrument panel to notify
the driver that the function is/was activated.
WARNING
City Safety may not be used to change how
the driver operates the vehicle. The driver
must not only rely on City Safety to brake the
vehicle.

City Safety™ (p. 335) Setting a warning distance for City
Safety
City Safety is always active, but the function's
warning distance can be adjusted.
NOTE The City Safety function cannot be deacti-
vated. It is activated automatically each time
the engine/electric motor is started.
The alert distance determines the sensitivity of
the system and regulates the distance at which
the light, sound and brake pulsations will be acti-
vated.
To select warning distance:
1.

Select Settings My Car IntelliSafe
in
the center display's Top view.
2. Under City Safety Warning, tap Late,
Normal or Early to set the desired warning distance.
If the driver feels that the Early setting is giving
too many warnings or finds them irritating, the
Normal or Late warning distance settings can
be selected instead.
If the driver feels that the warnings are too fre-
quent and distracting, the warning distance can
be reduced. This will reduce the total number of
warnings, but it will also result in City Safety pro-
viding warnings at a later stage.

DRIVER SUPPORT

339
The
Late warning distance setting should there-
fore only be used in exceptional cases, such as
when a more dynamic driving style is preferred.
WARNING •
No automatic system can guarantee
100% correct function in all situations.
You should therefore never test use of
City Safety in the direction of people, ani-
mals or vehicles – this could lead to
severe damage, serious personal injury or
even death.
• City Safety warns the driver if there is a
risk of collision, but the function cannot
reduce the driver's reaction time.
• Even if the warning distance has been set
to Early, warnings may be perceived as
late in certain situations – e.g. when there
are large speed differences or if the vehi-
cle ahead suddenly brakes heavily.
• With the warning distance set to
Early,
warnings come further in advance. This
may cause the warnings to come more
frequently than with warning distance
Normal, but is recommended since it can
make City Safety more effective.
NOTE The warning with direction indicators for Rear
Collision Warning is deactivated if the colli-
sion warning distance in the City Safety func-
tion is set to the lowest level "
Late".
The seat belt tensioning and braking func-
tions remain active.

• City Safety™ (p. 335) Detecting obstacles with City Safety
City Safety can detect vehicles, cyclists, large
animals and pedestrians.
VehiclesCity Safety detects most types of vehicles that
are either stationary, moving in the same direc-
tion as your vehicle or those described in "City
Safety in crossing traffic".
For City Safety to be able to detect a vehicle in
the dark, its headlights and taillights must be on
and clearly visible.
Cyclists Optimal examples of what City Safety would interpret to
be a cyclist: clear body and bicycle shapes.
For optimal performance, the system's function
for cyclist detection needs the clearest possible
information about the contours of the bicycle and
of the cyclist's head, arm, shoulders, legs, torso

and lower body in combination with normal
human movements.
If large portions of the cyclist's body or the bicy-
cle itself are not visible to the function's camera,
it will not be able to detect a cyclist.
The system can only detect adult cyclists riding
on bicycles intended for adults.
WARNING
City Safety is supplementary driver support,
but it cannot detect all cyclists in all situations
and, for example, cannot see:
• partially obscured cyclists.
• cyclists if the background contrast of the
cyclist is poor - warning and brake inter-
ventions may then be late or not occur at
all.
• cyclists in clothing that hides their body
contour.
• bikes loaded with large objects.
The driver is always responsible for ensuring
that the vehicle is driven correctly and with a
safety distance suitable for the speed.
Pedestrians Optimal examples of what the system considers to be a
pedestrian: clear body contours.
For optimal performance, the system's function
for pedestrian detection needs the clearest pos-
sible information about body and bicycle con-
tours. This entails being able to detect the con-
tours of the pedestrian's head, arm, shoulders,
legs, torso and lower body in combination with
normal human movements.
In order to detect a pedestrian, there must be a
contrast to the background, which could depend
on clothing, weather conditions, etc. If there is lit-
tle contrast, the person may be detected late or
not at all, which may result in a delayed reaction
from the system or no reaction at all.
City Safety can detect pedestrians even in dark
conditions if they are illuminated by the vehicle's
headlights.WARNING City Safety is supplementary driver support,
but it cannot detect all pedestrians in all sit-
uations and, for example, cannot see:
• partially obscured pedestrians, people in
clothing that hides their body contour or
pedestrians shorter than 80 cm (32 in.).
• pedestrians if the background contrast of
the pedestrians is poor - warning and
brake interventions may then be late or
not occur at all.
• pedestrians who are carrying large
objects.
The driver is always responsible for ensuring
that the vehicle is driven correctly and with a
safety distance suitable for the speed.

Large animals Optimal examples of what City Safety would interpret as
a large animal: stationary or moving slowly and with clear
body contours.
For optimal performance, the system's function
for detecting large animals (e.g. moose, horses,
etc.) needs the clearest possible information
about body contours. This entails being able to
detect the animal straight from the side in combi-
nation with normal movements for that animal.
If parts of the animal's body are not visible to the
function's camera, the system will not be able to
detect the animal.
City Safety can detect large animals even in dark
conditions if they are illuminated by the vehicle's
headlights.WARNING City Safety is supplementary driver support,
but it cannot detect all large animals in all sit-
uations and, for example, cannot see:
• partially obscured larger animals.
• larger animals seen from the front or from
behind.
• running or fast moving larger animals.
• larger animals if the contrast of the ani-
mal's background is poor - warning and
brake interventions may then occur late
or not at all.
• smaller animals such as cats and dogs.
The driver is always responsible for ensuring
that the vehicle is driven correctly and with a
safety distance suitable for the speed.

City Safety
can assist the driver when turning in
the path of an oncoming vehicle in an intersec-
tion. : Sector in which City Safety can detect an oncoming
vehicle in crossing traffic.
In order for City Safety to detect an oncoming
vehicle in situations where there is a risk of a col-
lision, that vehicle must be within the sector in
which City Safety can analyze the situation.
The following criteria must also be met:
• your vehicle's speed must be at least 4 km/h
(3 mph)
• your vehicle must be making a left turn
• the oncoming vehicle's headlights must be
on

WARNING
•
The "City Safety in crossing traffic" func-
tion is supplementary driver support
intended to improve driving safety – it
cannot handle all situations in all traffic,
weather and road conditions.
• Warnings and brake interventions due to
a collision risk with an oncoming vehicle
often come very late.
• Never wait for a collision warning or for
City Safety to intervene.
• City Safety is not a substitute for the driv-
er's attention and judgment. The driver is
always responsible for ensuring the vehi-
cle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

City Safety™ (p. 335) Limitations of City Safety in
crossing traffic
In certain situations, it may be difficult for City
Safety to help the driver avoid a collision with
crossing traffic. For example:
• on slippery roads when Electronic Stability
Control (ESC) is actively operating
• if an approaching vehicle is detected at a late
stage
• if the oncoming vehicle is partially obstructed
by another vehicle or object
• if the oncoming vehicle's headlights are off
• if the oncoming vehicle is moving erratically
and e.g. suddenly changes lanes at a late
stage.
NOTE The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit,
which has some general limitations – see the
section "Radar unit limitations".

DRIVER SUPPORT
344City Safety limitations
City Safety functionality may be reduced in cer-
tain situations.
Surroundings
Low objects
Hanging objects, such as flags for overhanging
loads or accessories such as auxiliary lights or
front protective grids that extend beyond the
height of the hood, may limit City Safety function-
ality.
Slippery road conditions
The extended braking distance on slippery roads
may reduce City Safety's capacity to help avoid a
collision. In these types of situations, the Anti-
lock Braking System and Electronic Stability Con-
trol (ESC 77
) will help provide optimal braking
power with maintained stability.
Backlighting
The visual warning signal in the windshield may
be difficult to detect in bright sunlight, if there are
reflections, or if the driver is wearing sunglasses
or not looking straight ahead.
Heat
If the temperature in the passenger compartment
is high due to e.g. bright sunlight, the visual warn-
ing signal in the windshield may be temporarily
disabled.
Camera and radar sensor's field of vision
The camera's field of vision is limited and in cer-
tain situations, it may be unable to detect pedes-
trians, large animals, cyclists or vehicles, or it may
detect them later than expected.
Vehicles that are dirty may be detected later than
clean vehicles, and in dark conditions, motorcy-
cles may be detected late or not at all.
If a text message displayed in the instrument
panel indicates that the camera/radar sensor is
obstructed, it may be difficult for City Safety to
detect pedestrians, large animals, cyclists, vehi-
cles or lane markings in front of the vehicle. City
Safety functionality may therefore be reduced.
Text messages may not be displayed for all situa-
tions in which the windshield sensors are
blocked. The driver must therefore always keep
the windshield in front of the camera/radar sen-
sor clean.
CAUTION Maintenance and replacement of City Safety
components may only be performed by a
workshop – an authorized Volvo workshop is
recommended.
Driver intervention
Backing up
City Safety is temporarily deactivated when the
vehicle is backing up.
Low speed
City Safety is not activated at very low speeds
under 4 km/h (3 mph). The system will therefore
not intervene in situations in which your vehicle is
approaching another vehicle very slowly, such as
when parking.
Active driver
Action by the driver always has priority. City
Safety will therefore not react or will react at a
later stage with a warning or intervention in situa-
tions in which the driver is clearly steering and
operating the accelerator pedal, even if a collision
is unavoidable.
An active and aware driving style may therefore
delay collision warnings and intervention in order
to minimize unnecessary warnings.
