Lighting107Adaptive forward lighting
The Adaptive forward lighting
functions are only available with Bi-
Xenon headlights. Light range, light
distribution and intensity of light are
variably triggered depending on the
light conditions, weather and road
type.
Playstreet lighting
Activated automatically at low speed
up to approx. 20 mph. The light beam is turned at an angle of -5°/3° to the
roadside.
Town lighting
Activated automatically at a speed up to approx. 30 mph and when streetlights are detected by the light sensor.
The light range is reduced by an
extended light distribution.
Country lighting
Activated automatically at a speed
range between approx. 30 and
72 mph. The beam of light and the
brightness is different between the
left and the right side.Motorway lighting
Activated automatically at a speed
above approx. 72 mph and minimal steering movements. It switches on
after a delay or directly when the vehicle is powerfully accelerated. The
light beam is longer and brighter.
Adverse weather lighting
Activated automatically up to a speed
of approx. 43 mph, when the rain
sensor recognises condensation or the wiper operates continuously. The
range, distribution and light intensity
is regulated variably depending on visibility.Dynamic curve lighting
The light beam pivots based on
steering wheel angle and speed,
improving lighting in curves.
Control indicator f 3 87.
Corner lighting On tight bends or when turning off,
depending on the steering angle or
the turn signal light, an additional left
or right reflector is switched on which
illuminates the road at an right angle
to the direction of travel. It is activated up to a speed of 25 mph.
Control indicator f 3 87.
122Driving and operating
Before restarting or to switch off the
engine, turn the key back to position
0 .
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Key lock release
Some vehicles with an automatic
transmission are equipped with an electronic key lock release system.
The key lock release is designed to
prevent ignition key removal unless
the selector lever is in P.
Starting the vehicle at low
temperatures
Starting the engine without additional
heaters is possible down to -25 °С for diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct fuel, performed services and a
sufficiently charged battery. With
temperatures below -30 °C the
automatic transmission requires a
warming phase of approx. 5 minutes.
The selector lever must be in position P .Automatic Starter Control
This function controls the engine
starting procedure. The driver does
not have to hold the key in position 3.
Once applied, the system will go on starting automatically until the engine
is running. Because of the checking
procedure, the engine starts running
after a short delay.
Possible reasons for a non-starting
engine:
■ Clutch pedal not operated (manual transmission)
■ Brake pedal not operated or selector lever not in P or N
(automatic transmission)
■ Timeout occurred
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but accelerator is released.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It starts the engine
automatically as soon as the clutch is depressed. A battery sensor ensures
that an Autostop is only performed if
the battery is sufficiently charged for
a restart.
Activation The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are fulfilled.
Driving and operating139
Alerting the driver
When approaching another vehicle
too rapidly, the collision alert warning page will be indicated in the Driver
Information Centre. Simultaneously a
warning chime sounds. Depress the
brake pedal, if it is required by the situation.
Deactivation
The system can be deactivated.
Press button V repeatedly until the
following message appears in the
Driver Information Centre.
General information
9 Warning
Forward collision alert is just a
warning system and does not
apply the brakes. When
approaching a vehicle ahead too
rapidly, it may not provide you
enough time to avoid a collision.
The driver accepts full
responsibility for the appropriate
following distance based on traffic,
weather and visibility conditions.
The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.
System limitations
The system is designed to warn only for vehicles, but may react also to
other metallic objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
■ on winding roads,
■ when weather limits visibility, e.g. fog, rain, or snow,
■ when the sensor is blocked by snow, ice, slush, mud, dirt, or
windscreen damage.
140Driving and operatingParking assist
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles,
and giving acoustic signals. It is the
driver, however, who bears full
responsibility for the parking
manoeuvre.
The system consists of four ultrasonic parking sensors in the rear bumper. If
the vehicle is equipped with a front
parking assist the system consists of
four additional ultrasonic parking
sensors in the front bumper.
Control indicator r 3 85.
Activation
When reverse gear is engaged, the
system is activated automatically.
The front parking assist can also be activated at a low speed by pressing
the r button.
An illuminated LED in the parking assist button indicates that the
system is ready to operate.
An obstacle is indicated by a buzzing
sound. The interval between the sounds becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm, the buzzing is continuous.
If the r button is pressed once
within an ignition cycle, the front
parking assist is always reactivated
when the vehicle speed goes below a certain value.
Deactivation
Deactivate the system by pressing
the r button.
The LED in the button will go out and
Park Assist Off will be displayed in the
Driver Information Centre.
The system is deactivated
automatically at a certain speed.
Fault
In the event of a fault in the system,
r illuminates or a vehicle message
is displayed in the Driver Information
Centre.
Additionally, r illuminates or a
vehicle message is displayed in the
Driver Information Centre if a
Driving and operating141
malfunction of the system due to
temporary conditions like snow
covered sensors is detected.

Important hints for using the
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 has to be paid to
low obstacles which can damage
the lower part of the bumper. If
such obstacles leave the detection area of the sensors during
approach of the vehicle, a
continuous warning tone will
sound.
Caution
Performance of the sensor can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
systems can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles involved (e.g.
off-road vehicles, mini vans,
vans). Object identification in the upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross section, like objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist will not avoid a
collision with objects which are out
of the detection range of the
sensors.
Notice
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
The sensor may detect a non-
existent object (echo disturbance)
caused by external acoustic or
mechanical disturbances.
Notice
The parking assist is deactivated
when the rear carrier system is
extended.
Rear view camera
The rear view camera assists the
driver when reversing by displaying a view of the area behind the vehicle.
The view of the camera is displayed
in the Colour-Info-Display.9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view and the
142Driving and operatingadvanced parking assist sensors,
e.g. below the bumper or
underneath the vehicle, are not
displayed.
Do not reverse the vehicle by only looking at the Info-Display and
check the surrounding behind and
around the vehicle before
reversing.
Activation
Rear view camera is automatically
activated when reverse gear is
engaged.
Functionality
The camera is mounted in the tailgate handle and has a viewing angle of
130°.
Due to the high position of the camera
the rear bumper can be seen on the
display as a guide to position.
The area displayed by the camera is
limited. The distance of the image that appears on the display differs from
the actual distance.
Guiding lines
Dynamic guiding lines are horizontal
lines in 1 metre intervals projected on
the picture to define the distance to
shown objects.
Trajectory lane of the vehicle is
shown in accordance with the
steering angle.
The function can be deactivated in the
menu Settings in the Info-Display.
