Active Emergency Braking Active emergency braking can help to reduce the damage from crashes with vehicles and obstacles directly
ahead, when a collision can no longer be avoided either by manual braking
or by steering. Before the active
emergency braking applies, the driver
is warned by the forward collision
alert 3 189.
The feature uses various inputs (e.g.
radar sensor, brake pressure, vehicle speed) to calculate the probability ofa frontal collision.
Active emergency braking operates automatically above walking speed,
provided that Auto collision
preparation setting is not deactivated
in the vehicle personalisation menu 3 131.
The system includes: ■ brake preparation system
■ emergency automatic braking
■ forward looking brake assist9 Warning
This system is not intended to
replace the driver responsibility of driving the vehicle and looking
ahead. Its function is limited to
supplemental use only. The driver
shall continue to apply the brake
pedal as the driving situation
dictates.
Brake preparation system
When approaching a vehicle ahead
so quickly that a collision is likely, the brake preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or automatic braking is requested.
The brake system is prepared so that braking can occur more rapidly.
Emergency automatic braking After the brake preparation and just
before the imminent collision, this
function automatically applies limited
braking to reduce the impact speed of
the collision.
Forward looking brake assist
In addition to brake preparation
system and emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. In this way,
depressing the brake pedal slightly

194Driving and operating
results immediately in a strong
braking. This function helps the driver brake quicker and stronger before theimminent collision.9 Warning
Active emergency braking is not
designed to apply strong
autonomous braking or to avoid automatically a collision. It is
designed to reduce the vehicle
speed before collision. It may not
react on stopped vehicles,
pedestrians or animals. After a
sudden lane change, the system
needs a certain time to detect the
next preceding vehicle.
The complete attention of the
driver is always required while
driving. The driver shall always be ready to take action and apply the brakes and steer to avoid
collisions. The system is designed
to work with all occupants wearing their seat belts.
System limitations
The active emergency braking has
limited or no function during rain,
snow or heavy dirt, as the radar
sensor can be covered by a water
film, dust, ice or snow. In case of
sensor blockage, clean the sensor
cover.
In some seldom cases the active
emergency braking system may
provide a short automatic braking in
situations that seem to be
unnecessary, for instance due to
traffic signs in a curve or due to
vehicles in another lane. This is
acceptable operation, the vehicle
does not need service. Firmly apply
the accelerator pedal to override the
automatic braking.
Settings Settings can be changed in the Auto
collision preparation menu in the
vehicle personalisation, 3 131.Fault

Front-rear parking assist9 Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area when driving backwards or
forwards while using parking
assist system.
The front-rear parking assist
measures the distance between the vehicle and obstacles in front and
behind the vehicle. The system gives acoustic signals and display
messages.
The system has four ultrasonic
parking sensors each in the rear and
front bumper.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency. The signal
for front obstacles sounds via the
front speakers, for rear obstacles it
sounds from the rear of the vehicle.Parking assist button and operation
logic
Front-rear parking assist is equipped
with button r. If the vehicle is
additionally equipped with advanced parking assist (see the following
separate description) the system is
equipped with button D. In this
case, both systems will be operated
by D .
Short press of r or D deactivates
or activates the front parking assist.
Long press of D (approx.
one second) activates or deactivates the advanced parking assist.

Advanced parking assist9 Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using
advanced parking assist.
The advanced parking assist system manoeuvres the driver into a parkingslot by giving instructions in the DIC
and acoustic signals. The driver must
control acceleration, braking, steering and gear shifting.
The system uses the sensors of the
front-rear parking assist in
combination with two additional
sensors on both sides of the front and rear bumper.

200Driving and operating
The parking slot suggestion of the
system is accepted when the vehicle is stopped by the driver within
10 metres after the "Stop" message is given. The system calculates the
optimal route into the parking slot. Then it manoeuvres the driver into the
slot by giving detailed instructions.The instructions in the display show:
■ A hint when driving faster than 18 mph.
■ The demand to stop the vehicle, when a parking slot is detected.
■ The direction of driving during the parking manoeuvre.
■ The steering wheel position during parking.
■ For some of the instructions a progress bar is shown.A successful parking manoeuvre is
indicated by the 'End position'
symbol.
Always pay attention to the sound of
the front-rear parking assist.
Continuous sound means that the
distance to an obstacle is less than
approx. 30 cm.
Changing the parking side
The system is configured to detect parking slots by default on the
passenger side. To detect parking
slots on the driver side, switch on turn
indicator to the driver side for the
duration of searching.

Driving and operating201
As soon as turn indicator is switched
off, the system searches for parking
slots on the passenger side again.
Display priorities
After activating the advanced parking assist, a message appears in the DIC.
Advanced parking assist indication in
the DIC can be inhibited by vehicle
messages with a higher priority. After approving the message by pressing
the SET/CLR button on the turn signal
lever, advanced parking assist
instructions appear again and the
parking manoeuvre can be continued.
Deactivation
The system is deactivated by:
■ short press of D if advanced
parking assist and front-rear
parking assist are activated
■ long press of D if advanced
parking assist is activated
■ parking manoeuvre successfully ended
■ driving faster than 18 mph
■ switching off the ignitionDeactivation by the driver or by the system during manoeuvring will beindicated by Parking Deactivated in
the DIC.
Fault A message appears in the DIC when:
■ There is a fault in the system.
■ The driver did not successfully complete the parking manoeuvre.
■ The system is not operational.
If an object is detected during parking instructions, Stop is indicated in the
DIC. Removing the object will resume the parking manoeuvre. If the object
is not removed, the system will be
deactivated. Press D for approx.
one second to activate the system
and search for a new parking slot.Basic notes on parking assist
systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and

202Driving and operatingcorrect distance indication in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
Notice
The parking assist system can be
activated and deactivated by
changing the settings in the
Info-Display. If a trailer coupling is
attached, it must be selected in the

It is possible that the sensor detects
a non-existing object (echo
disturbance) caused by external acoustical or mechanic
disturbances.
Advanced parking assist system
may not respond to changes in the
parking space after initiating a
parallel parking manoeuvre.
Notice
If engaging a forward gear and
exceeding a certain speed, the rear
parking assist will be deactivated
when the rear carrier system is
extended.
If engaging reverse at first, the
parking assist will detect the rear
carrier system and provide a buzzing
sound. Press r or D briefly to
deactivate the parking assist.
Notice
After use the advanced parking
assist requires a calibration. For
optimal parking guidance, a driving distance of at least 22 miles,
including a number of bends, is
required.Side blind spot alert
The Side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
"blind spot" zone. The system alerts
visually in each exterior mirror, when
detecting objects that may not be
visible in the interior and exterior
mirrors.
The system's sensors are located in
the bumper on the left and right side
of the vehicle.9 Warning
Side blind spot alert does not
replace driver vision.
The system does not detect: ■ vehicles outside the side blind zones which may be rapidly
approaching
■ pedestrians, cyclists or animals
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.

Driving and operating203
When the system detects a vehicle inthe side blind zone while driving
forward, either while passing a
vehicle or being passed, an amber
warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol B starts flashing
amber as a warning not to change
lanes.
Notice
If the passing vehicle is at least
6 mph faster than the passed
vehicle, the warning symbol B in the
relevant exterior mirror will not
illuminate.Side blind spot alert is active from
speeds of 6 mph up to 87 mph.
Driving faster than 87 mph
deactivates the system, indicated by
low lighting warning symbols B in
both exterior mirrors. Reducing the speed again will extinguish the
warning symbols. If a vehicle is then
detected in the blind zone, the
warning symbols B will illuminate as
normal on the relevant side.
When the vehicle is started, both exterior mirror displays will briefly
come on to indicate that the system is operating.
The system can be activated or
deactivated in the menu Settings in
the Info-Display, vehicle
personalisation 3 131.
Deactivation is indicated by a
message in the Driver Information
Centre (DIC).
Detection zones
The system sensor covers a zone of
approx. 3 metres on both sides of the
vehicle. This zone starts at each
exterior mirror and extends rearwardsby approx. 3 metres. The height of the zone is approx. between 0.5 metres
and 2 metres off the ground.
The system is deactivated if the
vehicle is towing a trailer.
Side blind spot alert is designed to
ignore stationary objects such as
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming
vehicles are not detected.
Fault
Occasional missed alerts can occur
under normal circumstances.
Side blind spot alert does not operate when the left or right corners of the
rear bumper are covered with mud,
dirt, snow, ice or slush. Cleaning
