Belt warning for driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts. It may light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and the front passenger have fastened their seat
belt.
For certain countries only: regardless of
whether the driver and the front passenger
have fastened their seat belts, the
7seat
belt warning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the front passenger have fas-
tened their seat belts.
i For more information on the 7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrumentc luster, seat
belt" (Y page 231).
Rear seat belt status indicator The rear-compartmen
tseat belt status indi-
cator tells you if the rear passengers have
their seat belts fastened.
The rear-compartment seat belt status indi-
cator indicates the rear seat on which the belt
is fastened. The üsymbol in the display
indicates a fastened seat belt. If a seat belt is
not fastened or if a seat is not occupied, the
ý symbol is displayed.
The rear-compartment seat belt status indi-
cator appears in the multifunction display for
around 30 seconds if:
R you drive off and reach a speed of approx-
imately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion.
R someone gets in or out of the vehicle and
the vehicle drives off again. Example: the occupant on the left rear seat is
secured46
Occupant safetySafety

In such cases, the distance warning signal
may:
R
give an unnecessary warning
R not give a warning
There is a risk of an accident. Always pay par-
ticula rattention to the traffi csituation and be
ready to brake, especially if the distance
warning signal alerts you. G
WARNING
The distance warning signal does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
Thus, the distance warning signal cannot pro-
vide a warning in all critical situations .There
is a risk of an accident. Always pay careful
attention to the traffic situation and be ready
to brake.
X To activate/deactivate: activate or deac-
tivate the distance warning signal in the on-
board computer (Y page 199).
When the distance warning signal is activa-
ted, the multifunction display shows the
Ä symbol as long as the HOLD function is
not activated (Y page 162). On vehicles with
Active Parking Assist, the Äsymbol is dis-
played when position Pis engaged or you are
driving faster than 35 km/h.
The distance warning signal can help you to
minimise the risk of a front-end collision with
a vehicle ahead or reduce the effects of such
a collision. If the distance warning signal
detects that there is a risk of a collision, you
will be warned visually and acoustically .The
distance warning signal cannot prevent a col-
lision without your intervention.
The distance warning signal will issue a warn-
ing at speeds of around 30 km/h or more if:
R the distance to the vehicle in front is too
short for the speed you are driving at for
several seconds. The ·distance warn- ing lamp then lights up in the instrument
cluster.
R you are rapidly approaching the vehicle in
front. An intermittent warning tone will
then sound and the ·distance warning
lamp will light up in the instrumentc luster.
X Brake immediately in order to increase the
distance from the vehicle in front.
or
X Take evasive action provided it is safe to do
so.
For the distance warnin gsignal to assist you
when driving, the function must be activated
in the on-board computer (Y page 199) and
be operational.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning.
With the help of the radar sensor system, the
distance warning signal can detect obstacles
that are in the path of your vehicle for an
extended period of time.
At speeds up to approximately 70 km/h, the
distance warning signal may also detect sta-
tionary obstacles, for example, stopped or
parked vehicles.
If you approach an obstacle and the distance
warning signal detects a risk of a collision, the
system will initially alert you both visually and
acoustically.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else cover-
ing the sensors
R snow or heavy rain
R interference by other radar sources
R the possibility of strong radar reflections,
for example, in multi-storey car parks
R a narrow vehicle travelling in front, e.g. a
motorbike
R a vehicle travelling in front on a different
line
Following damage to the front end of the vehi-
cle, have the configuration and operation of 64

G
WARNING
Adaptive Highbeam Assist is only an aid
designed to assist driving. The driver is
responsible for adjusting the vehicle's lighting
to the prevailing light, visio nand traffic con-
ditions.
The system may be impaired or deactivated:
R if there is poor visibility, e.g .due to snow,
rain, fog or spray
R if the area of the windscree naround the
optical sensor is dirty, misted up or covered
up, e.g. by a sticker
The system may not recognise the following
road users:
R road users that have no lighting, e.g. pedes-
trians
R road users that have poor lighting, e.g.
cyclists
R road users whose lighting is not clearly visi-
ble, e.g. road users behind a crash barrier
R on rare occasions: road users that have
lights that may be recognised too late or not
at all
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of or
approaching the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually.
You can use this function to set the head-
lamps to change between dipped beama ndmain beam automatically. The system recog-
nises vehicles with thei
rlights on, either
approaching fro mthe opposite direction or
travelling in front of your vehicle, and conse-
quently switches the headlamps from main
beam to dipped beam.
The system automatically adapts the dipped-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the main-beam headlamps.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. X
To activate: activate the Adaptive High-
beam Assist function using the on-board
computer (Y page 202).
X Turn the light switch to Ã.

Hill starta ssist G
WARNING
Never leave the vehicle when it is held by hill
start assist. After approximately one second,
hill start assist will no longer brake your vehi-
cle and it could roll away.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and depress it before the vehicle begins to
roll.
X Take your foot off the brake pedal.
The vehicle is then held for about a second.
X Pull away.
Hill start assist will not function if:
