* Option/accessory, for more information, see Introduction.185 General
Distance Warning (Distance Alert) is a function
that informs the driver about the time interval
to vehicles in front.
Distance Warning is active at speeds above
30 km/h and only reacts to vehicles driving in
front of the car, in the same direction. No dis-
tance information is provided for oncoming,
slow or stationary vehicles.
Orange warning lamp1.
An orange warning lamp in the windscreen illu-
minates with a constant glow if the distance to
the vehicle in front is shorter than the set time
interval.
NOTE
Distance warning is deactivated during the
time the adaptive cruise control is active.
WARNING
Distance warning only reacts if the distance
to the vehicle ahead is shorter than the pre-
set value - the speed of the driver's vehicle
is not affected.
Operation
Press the button in the centre console to switch
the function on or off. The function is switched
on if one lamp is illuminated in the button.Some combinations of the selected equipment
leave no vacant space for a button in the centre
console - in which case the function is handled

186* Option/accessory, for more information, see Introduction.
Different time intervals to the
vehicle in front can be
selected and shown in the
display as 1-5 horizontal lines
- the more lines the longer the
time interval. One line corre-
sponds to approximately
1 second to the vehicle in front, 5 lines approx-
imately 2.5 seconds.
The number of lines for the
selected time interval is
shown during the setting itself
and for several seconds after-
wards. Then a smaller scale
version of the symbol is
shown to the right of the dis-
play. The same symbol is also shown when
adaptive cruise control is activated.
NOTE
The higher the speed, the longer the calcu-
lated distance in metres for a specific time
interval.
The set time interval is also used by the
adaptive cruise control function, see
page 177.
Only use the time interval that is allowed in
accordance with local traffic regulations.
Limitations
The function uses the same radar sensor as
adaptive cruise control and the collision warn-ing system. For more information on the radar
sensor and its limitations, see page 181.
NOTE
Strong sunlight, reflections or strong varia-
tions in light intensity, as well as wearing
sunglasses, could mean that the warning
light in the windscreen cannot be seen.
Poor weather or winding roads could affect
the radar sensor's capacity to detect vehi-
cles in front.
The size of other vehicles could also affect
detection capacity, e.g. motorcycles. This
could mean that the warning lamp illumi-
nates at a shorter distance than the setting
or that the warning is temporarily absent.
Extremely high speeds can also cause the
lamp to illuminate at a shorter distance than
that set due to limitations in sensor range.

City Safety™
04
189
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 80 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 display
screen with its menu system, search and locate
Settings
Car settingsDriving support
systems
City Safety. Select the Off option.
For more information on the menu system MY
CAR, see page 144).
However, the function will be enabled the next
time the engine is started, regardless of
whether the system was enabled or disabled
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 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 infrared 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 the car is reversing City Safety™ cannot
be activated.
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, braking or
accelerating in a clear manner, even if a colli-
sion is unavoidable.

WARNING
Never look into the laser sensor (which
emits spreading invisible laser radiation) at
a distance of 100 mm or closer with magni-
fying optics such as a magnifying glass,
microscope, lens or similar optical instru-
ments - this would involve a risk of eye injury
(the illustration on page 188 shows sensor
location).
For more information on the laser sensor, see
page 9.
Symbols and messages in the display
In conjunction with automatic braking by the
City Safety™ system, one or more symbols

Function overview1.
Audio-visual warning signal in the event of
a collision risk.
Radar sensor
Camera sensor
Collision warningTogether with a camera sensor, the radar sen-
sor detects pedestrians, stationary vehicles as
well as vehicles driving in the same direction in
front of the car.
In the event of there being a risk of collision with
a pedestrian or such a vehicle your attention is
drawn with a red flashing warning signal and a
warning sound.
Brake supportIf the risk of collision still increases after the
collision warning then the brake support is acti-
vated. The brake support prepares the brake
system for rapid braking and the brakes are
applied gently, which may be noticed as a
slight jerk.
If the brake pedal is depressed sufficiently
quickly then full brake function is implemented.
Brake support also reinforces the driver's brak-
ing if the system considers that the braking is
not sufficient to avoid a collision.
Auto BrakeIf in this situation the driver has not yet started
to take evasive action and the risk of collision
is imminent then the automatic braking func-
tion is deployed, irrespective of whether or not
the driver brakes. Braking then takes place with
full brake force in order to reduce collision
speed, or with limited brake force if it is suffi-
cient to avoid collision.
Operation
Settings are made from MY CAR via the centre
console display screen and menu system. For
information on how the menu system is used,
see page 144.
NOTE
The Brake Support and Auto Brake func-
tions are always enabled - they cannot be
deactivated.

should be switched on or off: Search with the
menu system MY CAR via the centre console

Driving support systems
Collision Warning. For information on the
menu system, see page 144.
An activated function is tested at each engine
start by briefly illuminating the warning lamp's
separate points of light.
When starting the engine, the setting that was
selected when the engine was switched off is
obtained automatically.

Warning distance.
The warning distance determines the system's
sensitivity. Warning distance
Long provides an
earlier warning. First test with Long and if this
setting produces too many warnings, which
could be perceived as irritating in certain sit-
uations, then change to warning distance
Normal.
Only use warning distance
Short in excep-
tional cases, e.g. for dynamic driving.
NOTE
When the adaptive cruise control is in use
the warning lamp and warning sound will be
used by the cruise control even if the colli-
sion warning system is switched off.
The collision warning system warns the
driver in the event of a risk of a collision, but
the function cannot shorten driver reaction
time.
In order for the collision warning system to
be effective, always drive with the Distance
Alert set at time interval 4 – 5. see
page 185.
NOTE
Even if the warning distance has been set toLong warnings could be perceived as being
late in certain situations, e.g. when there are
large differences in speed or if vehicles in
front brake heavily.
Checking settingsThe settings required can be controlled on the
centre console display screen. Search with the
menu system MY CAR under Settings
Car
settings
Driving support systems
Collision Warning, see page 144.
Limitations
The collision warning system is active from and
including approx. 4 km/h.
The visual warning signal may be difficult to
notice in the event of strong sunlight, reflec-
tions, when sunglasses are being worn or if the
driver is not looking straight ahead. The warn-
ing sound should therefore always be acti-
vated.
On slippery road surfaces the braking distance
is extended, which may reduce the capacity to
avoid a collision. In such situations the ABS
and DSTC systems will provide best possible
braking force with maintained stability.
NOTE
The visual warning signal can be temporarily
disengaged in the event of high passenger
compartment temperature caused by
strong sunlight for example. If this occurs
then the warning sound is activated even if
it is deactivated in the menu system.
•Warnings may not appear if the dis-
tance to the vehicle in front is small or if
steering wheel and pedal movements
are large, e.g. a very active driving style.

196* Option/accessory, for more information, see Introduction.
Detection of pedestrians
Optimal examples of what the system regards as
pedestrians with clear body contours.
Optimal performance of the system requires
that the system function that detects pedes-
trians receives as unambiguous information as
possible about the contours of the body - this
implies the opportunity to identify the head,
arms, shoulders, legs, upper and lower body
combined with a normal human pattern of
movement.
If large parts of the body are not visible to the
camera then the system cannot detect a
pedestrian.
•In order for a pedestrian to be detected he/
she must appear full-length and have a
height of at least 80 cm.
•The system cannot detect a pedestrian
carrying larger items.
•The camera sensor's ability to see pedes-
trians at dusk and dawn is limited - just like
the human eye.
•The camera sensor's capacity to detect
pedestrians is deactivated when driving in
darkness and tunnels - even when street-
lights are lit.
WARNING
Collision Warning with Auto Brake & Pedes-
trian Detection is a means of assistance.
It cannot detect all pedestrians in all situa-
tions and it cannot see e.g. partially
obscured pedestrians, people in clothing
that hides the contours of the body or
pedestrians shorter than 80 cm.
•The driver is always responsible that the
vehicle is driven properly and with a
safety distance adapted to the speed.
Fault tracing and action
If the display shows the message Windscreen
Sensors blocked then this means that the
camera sensor is blocked and cannot detect
pedestrians, vehicles or road markings in front
of the car.In turn this means that the Collision Warning
with Auto Brake, Lane Departure Warning and
Driver Alert Control functions are not operating
with full functionality.
The following table presents possible causes
for a message being shown along with the
appropriate action.
CauseAction
The windscreen sur-
face in front of the
camera is dirty or
covered with ice or
snow.Clean the wind-
screen surface in
front of the camera
from dirt, ice and
snow.
Thick fog, heavy rain
or snow means that
the camera does not
work sufficiently
well.No action. At times
the camera does not
work during heavy
rain or snowfall.

If the vehicle is driven inconsistently then the
driver is alerted by an acoustic signal as well as
the text message
Driver Alert Time for a

driving ability does not improve.
WARNING
An alarm should be taken very seriously, as
a sleepy driver is often not aware of his/her
own condition.
In the event of an alarm or a feeling of tired-
ness; stop the car in a safe manner as soon
as possible and rest.
Studies have shown that it is equally as dan-
gerous to drive while tired as it is under the
influence of alcohol.
