9 Warning
Pull switch m for approx.
one second, the electric parking
brake operates automatically with
adequate force. For maximum
force, e.g. parking with trailer or on
inclines, pull switch m twice.
The electric parking brake is
applied when control indicator m
illuminates 3 88.
The electric parking brake can always
be activated, even if the ignition is off.
Do not operate electric parking brake
system too often without engine
running, as this will discharge the
vehicle battery.

dashes will be displayed: -.- s.
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 3 169.
The feature uses various inputs (e.g.
radar sensor, brake pressure, vehicle speed) to calculate the probability of
a frontal collision.
Active emergency braking operates automatically above walking speed,
provided that Auto collision
preparation setting is not deactivated
in the vehicle personalisation menu
3 105.
The system includes: ● brake preparation system
● emergency automatic braking
● forward looking brake assist9Warning
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
results immediately in a strong
braking. This function helps the driver
brake quicker and stronger before the imminent collision.

182Driving and operatingNote
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
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.
Note
After use the advanced parking
assist requires a calibration. For
optimal parking guidance, a driving
distance of at least 35 km, 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, whendetecting 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.
When the system detects a vehicle in the 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.
Note
If the overtaking vehicle is at least
10 km/h faster than the vehicle being
overtaken, the warning symbol B in
the relevant exterior mirror may not
illuminate.
Side blind spot alert is active from
speeds of 10 km/h up to 140 km/h.
Driving faster than 140 km/h
deactivates the system, indicated by
low lighting warning symbols B in
both exterior mirrors. Reducing the speed again will extinguish the

Speed limit signs are displayed in the
Driver Information Centre until the
next speed limit sign or end of speed
limit is detected or up to a defined sign timeout.
Indication of multiple signs on the
display is possible.
An exclamation mark in a frame
indicates that there is an add-on sign detected which cannot be recognised
by the system.
The system is active up to a speed of 200 km/h depending on the lighting
conditions. At night the system is
active up to a speed of 160 km/h.
As soon as vehicle speed becomes
slower than 55 km/h the display will
be reset and the content of the traffic
sign page will be cleared. The next
recognized speed indication will be
displayed.
Display indication
Traffic signs are displayed on the Traffic sign detection page in the
Driver Information Centre.

Driving and operating187The driver assistance systems donot relieve the driver from full
responsibility for vehicle
operation.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
● No operation of turn signals.
● No brake pedal operation.
● No active accelerator operation or speeding-up.
● No active steering.
If the driver is active, no warning will
be issued.
Activation
The lane departure warning system is activated by pressing ). The
illuminated LED in the button
indicates that the system is switched
on. When control indicator ) in the
instrument cluster illuminates green, the system is ready to operate.
The system is only operable at
vehicle speeds above 56 km/h and if lane markings are available.
When the system recognises an
unintended lane change, the control
indicator ) changes to yellow and
flashes. Simultaneously a chime
sound is activated.
Deactivation
The system is deactivated by
pressing ), the LED in the button
extinguishes.
At speeds below 56 km/h the system
is inoperable.
Fault The lane departure warning system
may not operate properly when:
● The windscreen is not clean.
● There are adverse environmental

Tyre pressure sensor matching
process
Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new wheel position after rotating the wheels or exchanging the
complete wheel set and if one or more
tyre pressure sensors were replaced.
The tyre pressure sensor matching
process should also be performed
after replacing a spare wheel with a
road wheel containing the tyre
pressure sensor.
The malfunction light w and the
warning message or code should
extinguish at the next ignition cycle.
The sensors are matched to the
wheel positions using a relearn tool,
in the following order: left side front
wheel, right side front wheel, right
side rear wheel and left side rear
wheel. The turn signal light at the
current active position is illuminated
until the sensor is matched.
Consult a workshop for service. There
are two minutes to match the first
wheel position, and five minutes
overall to match all four wheel
positions. If it takes longer, the
matching process stops and must be
restarted.
The tyre pressure sensor matching
process is:
1. Apply the parking brake.
2. Turn the ignition on.3. On vehicles with automatic transmission: set the selector
lever to P.
On vehicles with manual
transmission: select neutral.
4. Use MENU on the turn signal
lever to select the Vehicle
Information Menu in the Driver
Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.
6. Press SET/CLR to begin the
sensor matching process. A
message requesting acceptance
of the process should be
displayed.
Press SET/CLR again to confirm
the selection. The horn sounds
twice to indicate the receiver is in
relearn mode.
7. Start with the left side front wheel.
8. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
the tyre pressure sensor. A horn
chirp confirms that the sensor
identification code has been
matched to this wheel position.
