Driving and operating167FunctionalityIf equipped only with front camera the
active emergency braking operates in
forward gear above walking speed up to 85 km/h. With radar sensor and
front camera active emergency
braking operates in forward gear in
the range between walking speed
and 140 km/h.
A precondition is that forward collision
alert with front camera system is not
deactivated in the vehicle
personalisation menu and the seat
belts of the front passengers are
fastened 3 104.
The system includes: ● brake preparation system
● emergency automatic braking ● forward looking brake assist
● intelligent brake assist (only with radar sensor)
● forward collision alert
● front pedestrian protectionBrake preparation system
When approaching a vehicle ahead
or a pedestrian 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.
Emergency automatic braking
After activation of brake preparation
system and just before the imminent
collision, this function automatically
applies limited braking to reduce the
impact speed of the collision or
prohibit a crash. If active emergency
braking is applied, m flashes in the
instrument cluster. Depending on the
situation, the vehicle may
automatically brake moderately or
hard. Front automatic braking can
only occur if a vehicle ahead is
detected. On vehicles with front
pedestrian protection, front automatic braking can also occur when a
pedestrian ahead is detected.
Forward collision alert 3 164
Front pedestrian protection 3 169Emergency automatic braking may
slow the vehicle to a complete stop to
try to avoid a potential crash. If this
happens, emergency automatic
braking may engage the electric
parking brake to hold the vehicle at a stop. To release press the electric
parking brake button or firmly press
the accelerator pedal.9 Warning
Emergency automatic braking is
an emergency crash preparation
feature and is not designed to
avoid crashes. Do not rely on the
system to brake the vehicle.
Emergency automatic braking will
not brake outside of its operating speed range and only responds to
detected vehicles and
pedestrians.
Forward looking brake assist
In addition to the brake preparation
system and emergency automatic
braking, the forward looking brake
assist function makes the brake assist more sensitive. Therefore, pressing
Driving and operating181vehicle with mirrors unfolded. The
direction of the lines changes with the
position of the steering wheel.
The first horizontal line represents a
distance of about 30 cm beyond the edge of vehicle's rear bumper. The
upper horizontal lines represent
distances of about 1 m and 2 m.
This view is available in auto mode or in the view selection menu.Front view
The area in front the vehicle is
displayed in the screen. The vertical lines represent the width of the
vehicle with mirrors unfolded. The
direction of the lines changes with the
position of the steering wheel.
The first horizontal line represents a
distance of about 30 cm beyond the
edge of vehicle's front bumper. The
upper horizontal lines represent
distances of about 1 m and 2 m.
This view is available in auto mode or in the view selection menu.
Auto mode
This mode is activated by default.
Using sensors in the rear or in the
front bumper, the automatic view
changes from rear view or front view
to a view from above, as an obstacle
is approached during a manoeuvre.
Zoom view
The camera records the vehicle's
surroundings during the manoeuvre in order to reconstruct a view fromabove the rear or the front of the
vehicle in its near surroundings.Thus,
the vehicle can be manoeuvred
around obstacles nearby. This view is available with auto mode or in the
view selection menu.
180° view
The 180° view facilitates reversing
out of a parking bay, making it
possible to see the approach of
vehicles, pedestrians and cyclists.
This view is not recommended for
carrying out a complete manoeuvre.
It is made up of three areas: left 1,
centre 2 and right 3. This view is
available from the view selection menu only.
Vehicle care205● See the Owner's Manual forfurther information.
● Explosive gas may be present in the vicinity of the vehicle battery.
Power saving mode
This mode deactivates electrical
consumers to avoid excessive
discharging of the vehicle battery.
These consumers, such as the
Infotainment system, windscreen
wipers, low beam headlights,
courtesy light, etc. can be used for a
total maximum time of about
40 minutes after ignition is switched
off.
Changing into power saving mode
When power saving mode is
activated, a message appears in the
Driver Information Centre.
An active telephone call using the
hands-free option will be maintained
for around 10 minutes longer.Deactivating power saving mode
Power saving mode is deactivated automatically when the engine isrestarted. Run the engine for a
sufficient charge:
● for less than 10 minutes to use the consumers for approx.
5 minutes
● for more than 10 minutes to use the consumers for up to approx.
30 minutes
Heating functionalities Note
Individual heating functionalities,
such as heated seats or heated
steering wheel, may be temporarily
unavailable in the event of electrical
loading constraints. Functions will be resumed after some minutes.Diesel fuel system bleeding
If the tank has been run dry, the diesel fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of 40 seconds. Repeat this process after
no less than 5 seconds. If the engine
fails to start, seek the assistance of a
workshop.
