WARNING
Lane Keeping Assis tdoes not keep your vehi-
cle in its lane. It is only an aid and may detect
the lane markings on the road incorrectly or
not at all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray.
R there is glare, e.g. from oncoming traffic,
the sun, or reflection from other vehicles.
R the windscreen is dirty, misted up or cov-
ered, for instance by asticker, in the vicinity
of the camera
R several or no lane markings for asingle lane
are present.
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow.
R the distanc etothe vehicle in fron tistoo
smal land the lane markings thus cannot be
detected.
R the lane markings on the road are unclear,
e.g. near roadworks.
R the lane markings change quickly ,e.g.
lanes branch off, cross one another or
merge.
R the road is narrow and winding.
Lane Keeping Assist cannot detect road and
traffic conditions. It is not asubstitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt your driving
style to suit the prevailing road and weather
conditions. Always pay attention to traffic

Active Blind Spot Assist Important safety notes
Active Blin dSpot Assist uses aradar sensor
system to monitor the side areas of your vehi-
cle which are in back of the driver. Awarning
display in the exter iormirror sdraws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lane, you will
also receive an optical and audible collision
warning. If arisk of lateral collision is detec-
ted, corrective brakin gmay help you avoid a
collision. To support the course-correcting
brake application, Active Blind Spot Assist
also uses the forward-facin gradar senso rsys-
tem. Active Blind Spot Assist supports you
from aspeed of approximately 30 km/h. G
WARNING
Active Blin dSpot Assist is only an aid and may
detect vehicles/obstacles incor rectly or not
at all. Th
es ystem may be impaired or may not func-
tion if:
R there is poo rvisibility, e.g. due to snow,
rain, fog or spray.
R the rear and/or fron tsensors are dirty.
Active Blin dSpot Assist may not detect nar-
row vehicles, such as motor cycles or bicycles,
or only detect the mtoo late. It can notd etect
vehicles which are overtaken at asmall dis-
tance and then enter th eblind spot area.
Active Blind Spot Assist cannot detect road
and traffic conditions. It is not asubstitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt your driving
style to suit the prevailing road and weather
conditions. Always pay attention to traffic
conditions and your surroundings. Otherwise,
you may fail to recognise dangers in time,
cause an accident and injure yourself and oth-
ers.
The radar sensor syste misautomatically
deactivated near radio telescope facilities

For Active Blind Spot Assis ttoassist you
when driving, the radar sensor syste mmust
be activated (Y page 249)and operational.
Monitoring range
Active Blind Spot Assist monitors the area up
to three metres behind your vehicl eand
directl ynext to your vehicle as shown in the
diagram. For this purpose, Active Blin dSpot
Assist uses rada rsensors in the rear bumper. 212

Lane-correcting brak eapplication
If you leave your lane unde rcertain cir cum-
stances, the vehicle will brake briefl yonone

vehicle bac kinto the original lane.
Thi sfunction is available in the range between
60 km/ hand 200 km/h.
Al ane-correctin gbrake applicatio ncan only
be made after driving over asolid, recognis-
able lane marking. Befor ethis, awarning must be emitted by means of intermittent
vibration in the steering wheel. In addition, a
lane with lane markings on both sides must
be recognised. The brake application also
slightly reduces driving speed.
If al ane-correcting brake application occurs,
the following appears in the multifunction dis-
play: i
Afurther lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane. G
WARNING
Active Lane Keeping Assis tdoes not keep
your vehicle in its lane. It is only an aid
designed to assist driving. It is not asubstitute
for attentive driving. Corrective braking may
not always be sufficient to return your vehicle
to its original lane. In such cases, you must
steer the vehicle yourself to ensure that it
does not leave the lane.
Active Lane Keeping Assis tcannot detect the
current traffic situation or other road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles .Inrare cases, broken lines
or certain structures on the road surface may
be detected by the system as solid lane mark-
ings. You can, for example, countersteer gen-
tly at any time to cancel inappropriate braking
action, e.g. if you intentionally drive across a
solid lane marking.
Active Lane Keeping Assis tcannot take
weather conditions into account.
You are responsible for the vehicle's speed,
correct steering and for braking in good time.
Always adapt your driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and 216

The auxiliar yheatin gtimer func tion calcu-
lates the switch-on tim eaccording to the out-
sid etemperature so that the vehicle is pre-
heated by the departure time. When the
departure tim eisreached, the auxiliar yheat-
ing continues to heat for afurther five
minutes and then switches off. The auxiliary
heating adopts the THERMATI Cor
THERMOTRONI Ctemperature setting.
You can switc hoff th eauxiliary heating by
using the remote control or the auxiliary heat-
ing button on the centre console. G
WARNING
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in confined spaces without an extraction sys-
tem, e.g.
agarage. G
WARNING
When operating the auxiliary heating parts of
the vehicle can get very hot. Make sure that
the exhaust system does not under any cir-
cumstances come into contact with easily
ignitable material such as dry grass or fuels.
The material could otherwise ignite and set
the vehicle alight. Choos eyour parkin gspot
accordingly.
Operating the auxiliary heating is thus pro-
hibited at fillin gstations or when your vehicle
is being refuelled .You must therefore switch
off the auxiliar yheatin gatf illing stations.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for alonger
