Foot brake
03
131 General
The car is equipped with two brake circuits. If
one brake circuit is damaged then this will
mean that the brakes engage at a deeper level
and harder pressure on the pedal is needed to
produce the normal braking effect.
The driver's brake pedal pressure is assisted
by a brake servo.
WARNING
The brake servo only works when the engine
is running.
If the brake is used when the engine is switched
off then the pedal will feel stiff and more force
must be used to brake the car.
In very hilly terrain or when driving with a heavy
load the brakes can be relieved by using engine
braking. Engine braking is most efficiently used
if the same gear is used downhill as up.
For more general information on heavy loads
on the car, see page 359.
Anti-lock braking systemThe car is equipped with ABS (Anti-lock
Braking System) which prevents the wheels
from locking during braking. This means the
ability to steer is maintained and it is easier to
swerve to avoid a hazard for example. Vibrationmay be felt in the brake pedal when this is
engaged and this is normal.
A short test of the ABS system is made auto-
matically after the engine has been started
when the driver releases the brake pedal. A
further automatic test of the ABS system may
be made when the car reaches 10 km/h. The
test may be experienced as pulses in the brake
pedal.
Emergency brake lights and automatic
hazard warning flashers
Emergency brake lights are activated to alert
vehicles behind about sudden braking. The
function means that the brake light flashes
instead of - as in normal braking - shining with
a constant glow.
Emergency brake lights are activated at
speeds above 50 km/h if the ABS system is
working and/or in the event of sudden braking.
After the car's speed has been slowed below
10 km/h the brake light returns from flashing to
the normal constant glow - while at the same
time the hazard warning flashers are activated,
and they flash until the driver changes engine
speed with the accelerator pedal or they are
deactivated with their button, see page 91.
Cleaning the brake discsCoatings of dirt and water on the brake discs
may result in delayed brake function. This delay
is minimised by cleaning the brake linings.
Manual cleaning is advisable with wet road sur-
faces, prior to long-stay parking and after the
car has been washed. Carry this out by braking
gently during a short period while en route.
Emergency Brake AssistanceEmergency Brake Assistance EBA (Emergency
Brake Assist) helps to increase brake force and
so reduce braking distance. EBA detects the
driver's braking style and increases brake force
as necessary. The brake force can be rein-
forced up to the level when the ABS system is
engaged. The EBA function is interrupted when
the pressure on the brake pedal is reduced.
NOTE
When EBA is activated the brake pedal low-
ers slightly more than usual, depress (hold)
the brake pedal as long as necessary. If the
brake pedal is released then all braking
ceases.

133 General
FunctionA faint electric motor noise can be heard when
the electrical parking brake is being applied.
The noise can also be heard during the auto-
matic function checking of the parking brake.
If the car is stationary when the parking brake
is applied then it only acts on the rear wheels.
If it is applied when the car is moving then the
normal foot brake is used, i.e. the brake acts
on all four wheels. Brake function changes over
to the rear wheels when the car is almost sta-
tionary.
Low battery voltageIf the battery voltage is too low then the parking
brake can neither be released nor applied.
Connect a donor battery if the battery voltage
is too low, see page 116.
Applying the parking brake
Parking brake control - apply.
1. Press the foot brake pedal down firmly.
2. Press the control.
> The combined instrument panel symbol
starts flashing - once there is a
constant glow it is applied.
3. Release the foot brake pedal and make
sure that the car is at a standstill position.
•When parking the vehicle, always engage
1st gear (for manual gearbox) or put the
gear selector in position P (for automatic
gearbox).
In an emergency the parking brake can be
applied when the vehicle is moving by depress-
ing the control. When the control is released orthe accelerator pedal is depressed the braking
is interrupted.
NOTE
In the event of emergency braking at speeds
above 10 km/h a signal sounds during the
braking procedure.
Parking on a hillIf the car is parked facing uphill:
•Turn the wheels away from the kerb.
If the car is parked facing downhill:
•Turn the wheels towards the kerb.
WARNING
Get into the habit of always applying the
parking brake when parking on a slope -
leaving the car in gear, or in P if it has auto-
matic transmission, is not sufficient to hold
the car in all situation.

ning and the driver is wearing a seatbelt. The
parking brake is released immediately on
cars with automatic gearbox when the
accelerator pedal is depressed and the gear
selector is in position D or R.
Heavy load uphillA heavy load, such as a trailer, can cause the
car to roll backward when the parking brake is
released automatically on a steep incline.
Avoid this by depressing the control while driv-
ing off. Release the control when the engine
achieves traction.

•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).
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 .
DeactivateThe cruise control is switched off with the
steering wheel button
. The set speed is
cleared and cannot be resumed with the
button.
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.

180* Option/accessory, for more information, see Introduction.
NOTE
Activation of the cruise control below
30 km/h requires a vehicle in front within a
reasonable distance.
For shorter stops in connection with inching in
slow traffic or at traffic lights driving is auto-
matically resumed if the stops do not exceed
about 3 seconds - if it takes longer before the
car in front starts moving again then the cruise
control is set in standby mode. The driver must
then re-activate the cruise control in one of the
following ways:
•Press the steering wheel button .
or
•Press the accelerator pedal and accelerate
up to at least about 4 km/h (normal walking
pace).
The cruise control will then resume following
the vehicle in front.
NOTE
The cruise control can hold the car station-
ary for a maximum of 2 minutes - then the
parking brake is applied and the cruise con-
trol is disengaged.
•The driver has to release the parking
brake before the cruise control can be
reactivated.
Change of target
If the target vehicle in front suddenly turns then
there may be stationary traffic in front.
When the cruise control is following another
vehicle at speeds below 30 km/h and changes
target from a moving to a stationary vehicle, the
cruise control will slow down for the stationary
vehicle.
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 15 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 15 km/h and the
vehicle in front turns off so the cruise con-
trol no longer has a vehicle to follow.
Automatic braking ceases when
stationary
In certain situations the cruise control inter-
rupts braking when stationary. This means that
the foot brake is released and the driver must
brake himself/herself.
Cruise control releases the foot brake and is
set in standby mode when:
•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.

* Option/accessory, for more information, see Introduction.181
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.
