170* Option/accessory, for more information, see Introduction.
Active chassis - Four-C*
Active chassis, Four-C (Continously Controlled
Chassis Concept), regulates the characteris-
tics of the shock absorbers so that the car's
driving characteristics can be adjusted. There
are three settings: Comfort, Sport and
Advanced.
ComfortThis setting means that the car is perceived as
being more comfortable on rough and uneven
road surfaces. Shock absorption is soft and the
movement of the body is smooth and gentle.
SportThis setting means that the car is perceived as
being more sporty and is recommended for
more active driving. Steering response is faster
than in the Comfort mode. Shock absorption is
harder and the body follows the road in order
to reduce rolling during cornering.
AdvancedThis setting is only recommended on very even
and smooth road surfaces.
The shock absorbers are optimised for maxi-
mum roadholding and rolling in bends is further
minimised.
Operation
Chassis settings.
Use the buttons in the centre console to
change setting. The setting in use when the
engine is switched off is activated next time the
engine is started.
Speed related power steering*
Steering force increases with the speed of the
car to give the driver enhanced sensitivity. The
steering is firmer and more immediate on
motorways. Steering is light and requires no
extra effort when parking and at low speed.
The driver can choose between three different
levels of steering force for road responsiveness
or steering sensitivity. Go to the menu system
MY CAR and locate Settings
Car settings
Steering wheel force and select Low,
Medium or High.
For a description of the menu system, see
page 144. This menu cannot be accessed
while the car is in motion.

stored maximum speed - the display's
brackets disappear and the car's maxi-
mum speed is again limited.
Alarm for speed exceededOn steep roads the engine braking effect may
be inadequate and the selected maximum
speed exceeded. The driver is alerted about
this with an acoustic signal.
The signal is active until the driver has slowed
to below the selected maximum speed.
NOTE

Adaptive cruise control*
04
176* 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 181.
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 193) 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.
2Queue Assistant (in cars with automatic gearbox) can operate in the range of 0-200 km/h, see page 179.

Changing the speedIn active mode the speed is adjusted 5 km/h
with each press on
or . In active mode
the button
has the same function as but
results in a lower increase in speed. The last
press is stored in the memory.
NOTE
If any cruise control button is held
depressed for more than approx. 1 minute
then cruise control is disengaged. The
engine must be switched off in order to reset
cruise control.
In certain situations, cruise control cannot
be activated. Then the display shows
Cruise control Unavailable, see
page 183.
Set time intervalDifferent 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 distance. One line corre-
sponds to approximately
1 second, 5 lines approximately 2.5 seconds.
The time interval is increased or decreased
with the steering wheel keypad's thumbwheel
(or the buttons
/ for cars without Speed
limiter).
At low speed, when the distances are short, the
adaptive cruise control increases the time
interval slightly.
The adaptive cruise control allows the time
interval to vary noticeably in certain situations
in order to allow the car to follow the vehicle in
front smoothly and comfortably.
Note that a short time interval only allows the
driver a short time to react and take action if
any unforeseen traffic problem should arise.
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
Distance Warning is activated, see page 185.
NOTE
Only use the time interval that is allowed in
accordance with local traffic regulations.
If cruise control does not seem to react to
activation the reason may be that the time
interval to the closest vehicle prevents an
increase in speed.
The higher the speed, the longer the calcu-
lated distance in metres for a specific time
interval.
Temporary deactivation - standby mode
Press the steering wheel button to tempo-
rarily disengage the cruise control and set it in
standby mode - set speed is shown in brackets
in the display, e.g.
(100).
Keypad without Speed limiter*
Press the steering wheel button to tempo-
rarily disengage cruise control and set it in

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 minute7

•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 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/h8
•wheels lose traction
•brake temperature is high
•the radar sensor is covered e.g. by wet
snow or heavy rain (radar waves blocked).

with one press on the steering wheel button
- the speed is then set to the last stored
speed.

Keypad without Speed limiterThe cruise control is switched off with a short
press on 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 Assistant
In cars with automatic gearbox the adaptive
cruise control has the Queue Assistant function
(sometimes also referred to as "Queue
Assist").
Queue Assistant has the following functions:
•Extended speed range
•Change of target
•Automatic braking ceases when stationary
•Automatic activation parking brake.
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.
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.
8Does not apply to a car with Queue Assistant - it manages right down to stationary.

Automatic activation parking brakeIn some situations the cruise control applies
the parking brake in order to keep a stationary
car remaining stationary.
This takes place if:
•the driver opens the door or takes off his/
her seatbelt
•DSTC is changed from Normal to Sport
mode
•cruise control has held the car stationary
for more than 2 minutes
•the engine is switched off
•the brakes have overheated.
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 192) and the Distance Warning function
(see page 185). The function of the radar sen-
sor 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.
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.

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.
