City Safety™ 04
}}
167driver is always responsible for main-
taining a safe distance to the vehicle
ahead.
Function
Location of the laser sensor in the windshield
City Safety™ monitors traffic ahead of you
using a laser sensor mounted in the upper sec-
tion of the windshield. If a collision is imminent,
City Safety™ will automatically apply the
brakes at approximately 50% of the vehicle’s
full braking effect if you are traveling at speeds
between 2-18 mph (4-30 km/h).
\b
If the difference in speed between your
vehicle and the vehicle ahead is less than
approximately 9 mph (15 km/h), City Safety™ can help prevent a collision from
taking place.
\b If the difference in speed is between
approximately 10-18 mph (16-30 km/h),
City Safety™ alone cannot avoid a colli-
sion. The driver must apply the brakes for
full braking effect.
When the function activates and applies the
brakes, a message will appear in the informa-
tion display to indicate that the system is/has
been active.
NOTE \b
When City Safety™ applies the brakes,
the brake lights will illuminate.
\b In cases where City Safety™ has stop-
ped the vehicle, the system will then
release the brakes. The driver must
apply the brakes to keep the vehicle at
a standstill. Using City Safety™
NOTE
The City Safety™ function is activated auto-
matically each time the engine has been
switched off and restarted.

the next time the engine is started, even if it was
off when the engine was switched off.
Limitations
The sensor used by City Safety™ is designed
to detect cars and other larger motor vehicles
ahead of your vehicle in both daylight and dark-
ness.
However, there are certain limitations and the
laser sensor’s function may be reduced by, for
example, heavy rain or snowfall, or by dense
fog or thick, blowing dust or snow. Condensa-
tion, dirt, ice or snow on the windshield may
also interfere with the sensor’s function.
Objects such as warning flags hanging from
long objects on the roof or accessories such as
auxiliary lights or protective arches on the front
of the vehicle that are higher than the hood may
also impede the sensor’s function.
Braking distance to the vehicle ahead increa-
ses on slippery road surfaces, which may
reduce City Safety’s capacity to avoid a colli-
sion. In situations like this, the DSTC system
(see page 155) will help provide the best pos-
sible braking capacity and stability.
City Safety™ emits infrared light and measures
the way in which the light is reflected. There-
fore, vehicles or objects with low-reflective sur-faces may not be detected. Normally, the
license plate and taillight reflectors give the
rear section of a vehicle ahead sufficient reflec-
tive surfaces to be detected.
NOTE
\b
Keep the windshield in front of the laser
sensor free of ice, snow, dirt, etc. See
the illustration on page

167
\b Snow or ice on the hood deeper than
2 inches (5 cm) may obstruct the sen-
sor. Keep the hood free of ice and snow.
\b Do not mount or in any way attach any-
thing on the windshield that could
obstruct the laser sensor. Troubleshooting
If Windshield sensors blocked appears in
the information display, this indicates that the
City Safety™ laser sensor is obstructed in
some way and cannot detect vehicles ahead of
you, which means that the system is not func-
tioning.
However, this message will not be displayed in
all situations in which the sensor is obstructed.
For this reason, the driver must ensure that the
area of the windshield in front of the sensor is
always kept clean.

WARNING
The laser sensor emits light when the igni-
tion is in mode II or higher, even if City
Safety™ has been switched off.
WARNING Eye injury may occur if any of the following
points are not followed:
\b
It is essential that all pertinent instruc-
tions be followed when handling laser
instruments. Testing, repairing, remov-
ing, adjusting and/or replacing any
components in the laser sensor may
only be done by a trained and qualified
Volvo service technician.
\b Do not remove the laser sensor (includ-
ing removal of the lenses). A laser sen-
sor that has been removed belongs to
laser class 3B according to standard
IEC 60825-1. Devices in laser class 3B
present a risk of injury to the eyes.
\b The laser sensor’s connector must be
disconnected before the sensor is
removed from the windshield.
\b The laser sensor must be mounted in
place on the windshield before con-
necting the sensor’s connector.
\b Do not view the laser sensor (which
emits spreading, invisible laser beams)
with optical instruments from a distance
of less than 4 inches (100 mm). Symbols and messages in the display
When City Safety™ automatically applies the
brakes, one or more of the symbols in the main
instrument panel may illuminate and its asso-
ciated message will be displayed.

Adaptive Cruise Control (ACC)*04
}}
* Option/accessory, for more information, see Introduction. 173
WARNING\b
Adaptive cruise control is not a collision
avoidance system. The driver is always
responsible for applying the brakes if
the system does not detect another
vehicle.
\b Adaptive cruise control does not react
to slow moving or stationary vehicles. The distance to the vehicle ahead (in the same
lane) is measured by a radar sensor. Your vehi-
cle\fs speed is regulated by acceleration and
braking. The brakes may emit a sound when
they are being modulated by the adaptive
cruise control system. This is normal.
WARNING
The brake pedal moves when the adaptive
cruise control system modulates the
brakes. Do not rest your foot under the
brake pedal.
The adaptive cruise control system is designed
to follow the vehicle ahead of you in the same
lane, at a set time interval.
If the radar sensor has not detected a vehicle
ahead, the system will then attempt to maintain
the set speed. This is also the case if the speed of the vehicle ahead exceeds the speed that
you have set.
The adaptive cruise control system is designed
to smoothly regulate speed. However, the
driver must apply the brakes in situations that
require immediate braking. This applies when
there are great differences in speed between
vehicles, or if the vehicle ahead brakes sud-
denly.
WARNING
Due to limitations in the radar sensor, brak-
ing may occur unexpectedly or not at all,
see page 175.
Adaptive cruise control can only be activated
at speeds above 20mph (30 km/h). If speed
falls below 20 mph (30 km/h) or if engine speed
(rpm) becomes too low, adaptive cruise control
disengages and will no longer modulate the
brakes. In situations when adaptive cruise con-
trol cannot be activated Cruise Control
Unavailable is shown in the display.
WARNING
When adaptive cruise control disengages,
the brakes will not be modulated automati-
cally. The driver must assume full control
over the vehicle.
Warning light-driver braking requiredAdaptive cruise control has a braking capacity
that is equivalent to approximately 30% of the
vehicle\fs total braking capacity. In situations
requiring more brake force than ACC can pro-
vide, if the driver does not apply the brakes, an
audible signal will sound and a red warning
light will illuminate in the windshield to alert the
driver to react.
NOTE Strong sunlight, reflections, extreme light
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may
make the visual warning signal in the wind-
shield difficult to see.
WARNING
Cruise control only warns of vehicles
detected by the radar sensor, see
page 172. In some cases there may be no
warning or the warning may be delayed. The
driver should always apply the brakes when
necessary.

Setting a speed
Use the or buttons to store (set) the
vehicle\fs current speed. The set speed, for
example 55 mph, is shown in the display.
NOTE Adaptive cruise control cannot be engaged
at speeds below 20 mph (30 km/h).
The “car” symbol illuminates
on the left side of the display
when the radar sensor
detects another vehicle
ahead. The distance to a vehi-
cle ahead is only regulated
when this symbol is illumi-
nated.
Adjusting the set speedAfter a speed has been set, it can be increased
or decreased by using the or buttons.
When the system is in active mode, the but-
ton has the same function as , but results in
a smaller increase in speed.
NOTE \b
If one of the adaptive cruise control but-
tons is pressed for more than approxi-
mately one minute, ACC will be deacti-
vated. The engine must then be
switched off and restarted to reset ACC.
\b In some situations cruise control cannot
be activated. Cruise Control
Unavailable is shown in the display,
see page 177.
Setting a time intervalThe set time interval to vehicles ahead is
increased with and decreased with .
The current time interval is shown briefly in the
display following adjustment.
Five different time intervals
can be selected and are
shown in the display as 1–5
horizontal bars. The greater
the number of bars, the longer
the time interval. At low
speeds, when the distance to
the vehicle ahead is short, ACC increases the
time interval slightly. In order to follow the vehi-
cle ahead as smoothly as possible, ACC allows
the time interval to vary considerably in certain
situations. G027123

* Option/accessory, for more information, see Introduction. 175
WARNING\b
Only use a time interval that is suitable
in current traffic conditions.
\b A short time interval gives the driver lim-
ited reaction time if an unexpected sit-
uation occurs in traffic. The number of bars indicating the selected
time interval are shown while the setting is
being made and for several seconds afterward.
A smaller version of the symbol is then shown
to the right in the display. The same symbol is
also displayed when Distance Alert is acti-
vated, see page 179 .
Deactivating and resuming settingsCruise control is deactivated, either with a
short press on
, or by action taken by the
driver, such as braking, etc. The set speed, for
example 55 mph, is then shown in parenthe-
ses. Speed and time interval are resumed by
pressing .
WARNING
There may be a significant increase in speed
after the
button has been pressed.
A short press on in standby mode or a long
press in active mode deactivates cruise con- trol. The set speed is then cleared and cannot
be resumed.
When ACC is activated, the vehicle’s speed
increases by approximately 1 mph (1 km/h)
each additional time is pressed.
Deactivation due to action by the driverACC is deactivated:
\b
when the brakes are applied
\b if the gear selector is moved to
N
\b if the accelerator pedal is depressed for an
extended period.
NOTE If the accelerator pedal is only depressed for
a short time, such as when passing another
vehicle, ACC is deactivated temporarily and
is reactivated when the pedal is released.
Automatic deactivationAdaptive cruise control is linked to other sys-
tems such as ABS, the stability and traction
control system (DSTC), and the Distance Alert
System. If any of these systems are not func-
tioning properly, adaptive cruise control is
automatically deactivated.
In the event of automatic deactivation a signal
will sound and the message
Cruise Control
Canceled is shown in the display. The driver must then intervene and adapt the vehicle\fs
speed to the surrounding traffic.
Automatic deactivation may be caused if:
\b
the vehicle\fs speed falls below 20 mph
(30 km/h)
\b the wheels lose traction or if the anti-lock
brake system (ABS) is activated
\b brake temperature is high
\b engine speed (rpm) is too low
\b the radar sensor is obstructed by, for
example, wet snow or rain.
The radar sensor and its limitations
The radar sensor is used by both Adaptive
Cruise Control and the Collision Warning Sys-
tem with Auto-brake. It is designed to detect
cars or larger vehicles driving in the same
direction as your vehicle.WARNING Accessories or other objects, such as extra
headlights, must not be installed in front of
the grille.
Modification of the radar sensor could make
its use illegal.
The radar sensor\fs capacity to detect vehicles
ahead is impeded:
