Always make sure that the seat-belt extenderis retracted during a journey.
The seat-belt extender for the driver and front
passenger helps you fasten your seat belt. Seat-
belt extender =is extended when the respec-
tive door is closed and the SmartKey is turned to
position 1or 2in the ignition lock.
You can also extend seat-belt extender =with
seat-belt extender button ?.
XPress seat-belt extender button ?.
Seat-belt extender =extends.
Seat-belt extender =is retracted again if:
Rthe belt tongue is engaged in the seat belt
buckle.
Rthe belt tongue is not engaged in the seat belt
buckle within 60 seconds.
Rthe respective door is opened.
Rthe SmartKey is turned to position 0in the
ignition lock.
Ryou release the seat backrest and fold it for-
wards.
Rthe front-passenger seat is unoccupied after
approximately five seconds.
If you press seat-belt extender button ?after
this, seat-belt extender =will not extend.
Basic illustration
XAdjust the seat (Ypage 91).
The seat backrest must be in an almost ver-
tical position.
XPull the seat belt smoothly out of seat-belt
extender =and engage belt tongue ;into
belt buckle :.
The seat belt on the driver’s seat and the
front-passenger seat may be tightened auto-
matically, see "Belt adjustment"
(
Ypage 45).
XIf necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
In order to attach the child restraint system
securely in the vehicle, the seat belts in the rear
are equipped with a special seat belt retractor.
Further information can be found under "Special
seat belt retractor" (
Ypage 57).
Automatic comfort-install feature
The front seat belts have an automatic comfort-
install feature. The automatic comfort-fit feature
reduces the retraction force of the seat belts.
The seat belts are thus routed more comfortably
for the driver and front passenger.
Releasing seat belts
!Make sure that the seat belt is fully rolled up.
Otherwise, the seat belt or belt tongue will be
trapped in the door or in the seat mechanism.
This could damage the door, the door trim
panel and the seat belt. Damaged seat belts

Safety

RAdjust the seats properly before beginning
your journey. Always make sure that the seat
is in an almost upright position. The center of
the head restraint must support the head at
about eye level.
RMove the driver's and front-passenger seats
as far back as possible. The driver's seat posi-
tion must allow the vehicle to be driven safely.
ROnly hold the steering wheel on the outside.
This allows the air bag to be fully deployed.
RAlways lean against the backrest while driv-
ing. Do not lean forwards or lean against the
door or side window. You may otherwise be in
the deployment area of the air bags.
RAlways keep your feet in the footwell in front
of the seat. Do not put your feet on the dash-
board, for example. Your feet may otherwise
be in the deployment area of the air bag.
RFor this reason, always secure persons less
than 5 ft (1.50 m)tall in suitable restraint sys-
tems. Up to this height, the seat belt cannot
be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
RAlways secure children under twelve years of age and less than 5 ft (1.50m)tall in suitable
child restraint systems.
RChild restraint systems should be installed on
the rear seats.
ROnly secure a child in a rearward-facing child
restraint system on the front-passenger seat
when the front-passenger front air bag is
deactivated. If the PASSENGER AIR BAG OFF
indicator lamp is permanently lit, the front-
passenger front air bag is deactivated
(
Ypage 41).
RAlways observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" (
Ypage 48) and on "Children in the
vehicle" (Ypage 56) in addition to the child
restraint system manufacturer's installation
and operating instructions.
Objects in the vehicle interior may prevent
an air bag from functioning correctly. Before
starting your journey and to avoid risks resulting from the speed of the air bag as it deploys, make
sure that:
Rthere are no people, animals or objects
between the vehicle occupants and an air
bag.
Rthere are no objects between the seat, door
and B-pillar.
Rno hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks.
Rno accessories, such as cup holders, are
attache d to the vehicle within the deployment
area of an air bag, e.g. to doors, side windows,
rear side trim or side walls.
Rno heavy, sharp-edged or fragile objects are in
the pockets of your clothing. Store such
objects in a suitable place.
GWARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.
GWARNING
Sensors to control the air bags are located in
the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensors being impaired. The air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door pan-
eling carried out at a qualified specialist work-
shop.

Radar sensors
The Active BlindSpo t Assist radar sensors are
integrated into the front and rear bumpers and
behind a cover inthe radiator trim. Make sure
that the bumpers and the cover inthe radiator
grill are free of dirt, ice or slush. The rear sensors
must not becovered, for example bycyc leracks
or overhanging cargo. Fol lowing a severe impact
or inthe event of damage to the bumpers, have
the function of the radar sensors checked at a
qualif ied specialist workshop.ActiveBlindSpo t
Assist may otherwise no longer work properly.
Monitoring area
GWARNING
Active Blind Spot Assist does not detect all
traff icsituations and road users. There isa
risk of an acc ident.
Alwa ys make sure that there issuff icientdis-
tance on the side for other traff icor obstacles.
The detection of obstacles can beimpaired in
the case of:
Rthere is dirt on the sensors or anything else
covering the sensors
Rpoor vis ibility, e.g. due to rain, snow or spray
Vehicles inthe monitoring range are then not
indicated or indicated with a delay.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv- ing inthe midd le of their lane. This may be the
case ifthere are vehicles at the edge of their
lane.
Due to the nature of the system:
Rwarnings may be issued inerror when driving
close to crash barriers or similar solid lane
borders.
Rthe warning is canceled when driving for an
extended period next to long vehicles, such as
trucks.

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunction
camera :at the top of the windshield. Various
different areas to the front, rear and side of your
vehicle are also monitored with the aid of the
radar sensor system. Active Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin-
tentionally. If you do not react to the warning, a
lane-correcting application of the brakes can
bring the vehicle back into the original lane.
This function is available in the range between
40 mph and 120 mph (60 km/h and 200 km/h).
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must be
operational
Important safety notes
If you fail to adapt your driving style, Active Lane
Keeping Assist can neither reduce the risk of
accident nor override the laws of physics. Active
Lane Keeping Assist cannot take account of
road and weather conditions. It may not recog- nize traffic situations. Active Lane Keeping
Assist is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
you
r lane.
Active Lane Keeping Assist cannot continuously
keep your vehicle in its lane.
GWARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
Rgive an unnecessary warning and then
make a course-correcting brake application
to the vehicle
Rnot give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
The system may be impaired or may not function
if:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncoming traffic, the
sun or reflections (e.g. when the road surface
is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
Rthe radar sensors in the front or rear bumpers
or the radiator trim are dirty, e.g. obscured by
snow
Rthere are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
