Curve and cornering lights
On tight bends or when turning off,
depending on the steering angle or
the indicator light signal, an additional left or right reflector is switched on
which illuminates the road in the
direction of travel. It is activated up to
a speed of 70 km/h.
Town light
Activated automatically at a speed up to approx. 55 km/h. In situations with
exterior ambient light both cornering lights are switched on with reduced
intensity. The light is wide and
symmetrical.
Country light
Activated automatically at a speed
range between approx. 55 and
180 km/h. The beam of light and the
brightness is different between the left and the right side.
High beam assist This feature allows high beam to
function as the main driving light at
night and when vehicle speed
exceeds 40 km/h.
It switches automatically to low beam
when:
● The camera or a sensor in the windscreen detects the lights of
oncoming or preceding vehicles.
● The vehicle speed drops below 20 km/h.
● It is foggy or snowy.
● Driving in urban areas.
If there are no restrictions detected,
the system switches back to high
beam.
Activation
122LightingThe high beam assist is activated by
pushing the indicator lever twice. The high beam is switched on
automatically at a speed above
40 km/h.
The green control indicator f
illuminates continuously when the
assist is activated, the blue one 7
illuminates when high beam is on.
Control indicator f 3 97.
Deactivation
Push indicator lever once. It is also deactivated when front fog lights are switched on.
If a headlight flash is activated when
the high beam is on, the high beam
assist will be deactivated.
If a headlight flash is activated when
the high beam is off, the high beam
assist will remain activated.
The latest setting of the high beam
assist will remain after the ignition is
switched on again.Reverse parking function
To assist driver's orientation when
parking, both corner lights and
reversing light illuminate when
headlights are on and reverse gear is
engaged. They remain illuminated for a short time after disengaging reverse
gear or until driving faster than
7 km/h in a forward gear.
Eco mode If the vehicle stops, e. g. due to traffic lights, an energy saving mode forheadlights is activated.
Dynamic automatic headlight
levelling
To prevent oncoming traffic frombeing dazzled, headlight levelling is
automatically adjusted based on
vehicle inclination information.

Driving and operating135Driving hints
Control of the vehicle
Never coast with engine not
running (except during Autostop)
Many systems will not function in this
situation (e.g. brake servo unit, power steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 139.
Pedals To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
Use only floor mats, which fit properly
and are fixed by the retainers on the
driver side.Steering
If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.
A vehicle message will be displayed
in the Info-Display.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 10 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
Starting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period fuel and engine oil consumption may be
higher and the cleaning process of the diesel particle filter may take
place more often. Autostop may be
inhibited to allow for charging the
battery.
Diesel particle filter 3 143.
Driving and operating149Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek the assistance of a workshop before
continuing the journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 94.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting-off the system performs
a self-test which may be audible.
Control indicator u 3 94.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
150Driving and operating9Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
brake pedal at the same time.
Control indicator R 3 94.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Hill start assist
The system helps prevent unintended movement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, the brakes
remain on for a further two seconds.
The brakes release automatically as
soon as the vehicle begins to
accelerate.
The hill start assist is not active during
an Autostop.
Stop-start system 3 139.Ride control systems
Traction Control system The Traction Control system (TC) is a component of the Electronic Stability
Control (ESC) 3 151.
TC improves driving stability when necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational after each engine
start as soon as the control indicator
b extinguishes.
When TC operates b flashes.
Driving and operating159When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre 3 98 . Press
MENU on the turn signal lever to
select Vehicle Information
Menu ? and turn the adjuster
wheel to choose following distance
indication page.
The minimum indicated distance is
0.5 s.
If there is no vehicle ahead or the vehicle ahead is out of range, two
dashes will be displayed: -.- s.
Parking 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.
Activation
After ignition is switched on, the rear
parking assist is activated.
The front parking assist can also be activated at a low speed by pressing
r .
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.
160Driving and operatingIf r is pressed once within an
ignition cycle, the front parking assist
is reactivated if the vehicle speed
goes below a certain value and if the
vehicle speed has not exceeded 25 km/h beforehand.
Deactivation
Deactivate the system by pressing r .
The LED in the button will go out and
Park Assist Off will be displayed in the
Driver Information Centre.
If the parking assist is deactivated
manually, it will be reactivated
automatically the next time the
ignition is switched on.
The system is deactivated
automatically at a certain speed.
Fault
In the event of a fault in the system, a
vehicle message is displayed in the Driver Information Centre.
Additionally, a vehicle message is
displayed in the Driver Information
Centre if a malfunction of the system
due to temporary conditions, e.g.
snow covered sensors is detected.Vehicle messages 3 104.
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 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 correct 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.
