Forward-facing child restraint system
If it is absolutely necessary to fit a forward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible. Fully
retract the seat cushion length. The entire base of the child restraint system must always rest on
the seat cushion of the front-passenger seat.
The backrest of the child restraint system must, as far as possible, lie flat against the backrest of
the front-passenger seat. The child restraint sys- tem must not touch the roof or be put under
strain by the head restraint. Adjust the angle of
the seat backrest and the head restraint posi-
tion accordingly. Always make sure that the
shoulder belt strap is correctly routed from the
vehicle belt outlet to the shoulder belt guide on the child restraint system. The shoulder belt
strap must be routed forwards and downwards
from the vehicle belt outlet. If necessary, adjust
the vehicle belt outlet and the front-passenger
seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
(Y page 59) in addition to the child restraint
system manufacturer's installation and operat-
ing instructions. Suitable positioning of the child
restraint system
Introduction Only child restraint systems approved in accord-
ance with ECE standards ECE R44 or ECE R129 (i-Size child restraint systems) are permitted for
use in the vehicle.
For certain child restraint systems in weight cat- egories II or III, this can mean that the area of
use is restricted. The maximum size setting of
the child restraint system may not be possible
due to possible contact with the roof.
"Universal" category child restraint systems can
be recognised by their orange approval label and the text "Universal" or an "i-Size" label. Example: approval label on the child restraint
system
ISOFIX or i-Size child restraint systems of the
“Universal“ category can be used on seats label- led U, UF, IUF or i-U in accordance with the fol-
lowing tables:
R Suitability of the seats for attaching belt-
secured child restraint systems
R Suitability of the seats for attaching ISOFIX

Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front, for vehicle speed, for braking in
good time and for staying in lane. Always adapt your driving style to suit the prevailing road and
weather conditions and maintain a safe distance from the vehicle in front. Drive carefully.
The driving safety systems described work as
effectively as possible only when there is ade-
quate contact between the tyres and the road
surface. Please pay special attention to the
notes on tyres, recommended minimum tyre
tread depths etc. (Y page 310).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. ABS (Anti-lock Braking System)
General notes ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 8 km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only
brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac- tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems, includ-
ing driving safety systems, will also become
inoperative. Observe the information on the ABS warning lamp (Y page 250) and display mes-
sages which may be shown in the instrument
cluster (Y page 217).
Braking X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions; this serves as a
reminder to take extra care while driving. BAS (Brake Assist)
General notes BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes i
Read the "Important safety notes" section
(Y page 66). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking. 66

X
Keep the brake pedal depressed firmly until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. Active Brake Assist
General information i
Read the "Important safety notes" section
(Y page 66).
Active Brake Assist consists of a distance warn-
ing function with an autonomous braking func-
tion and braking assistance appropriate to the
situation.
Active Brake Assist can help you to minimise the risk of a collision with the vehicle travelling in
front or reduce the effects of such a collision.
If Active Brake Assist detects that there is a risk
of collision, you will be warned visually and
acoustically. If you do not react to the visual and audible collision warning, autonomous braking
can be initiated in critical situations. If you apply
the brake yourself in a critical situation, Adap-
tive Brake Assist supports you with braking
assistance appropriate to the situation.
Important safety notes Detection of hazardous situations can be par-
ticularly impaired by:
R
dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
R new vehicles or after servicing is carried out
on the Active Brake Assist system
Read the important safety notes in the "Run-
ning-in notes" section (Y page 132).
Following damage to the front end of the vehicle, have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at low speeds where no visible damage to the front of
the vehicle is apparent.
Activating/deactivating Active Brake Assist is active after every ignition
cycle.
You can activate or deactivate Active Brake
Assist (Y page 209) in the on-board computer.
When the system is deactivated, the distance
warning function and the autonomous braking
function are also deactivated.
If Active Brake Assist is deactivated, the æ
symbol appears in the assistance graphic dis-
play.
Distance warning function General information
The distance warning function can help you to
minimise the risk of collision with the vehicle in
front or reduce the effects of such a collision. If the distance warning function detects a risk of
collision with the vehicle in front, you will be
warned visually and audibly.
Important safety notes
i Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 66). G
WARNING
The distance warning function does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations. Driving safety systems
67Safety
Z

Braking assistance appropriate to the situation
can also detect stationary objects, up to vehicle
speeds of around 70 km/h.
If braking assistance appropriate to the situa-
tion demands particularly high brake pressure,
preventative passenger protection measures
(PRE-SAFE ®
) are triggered simultaneously
(Y page 53).
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again if: R you release the brake pedal
R a danger of collision with the vehicle in front
no longer exists
R no obstacle is detected in front of your vehicle
Braking assistance appropriate to the situation
is then deactivated.
Important safety notes i Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 66).G
WARNING
Adaptive Brake Assist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, Adaptive Brake Assist may not
intervene in all critical conditions. The risk of
an accident remains.
Always pay careful attention to the traffic sit- uation and be ready to brake. G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist might:
R intervene unnecessarily
R not intervene
The risk of an accident remains.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation. Due to the nature of the system, complex but
non-critical driving conditions may also cause
Active Brake Assist to intervene.
Even if Active Brake Assist is not available due to a malfunction in the radar sensor system, the
brake system is still available with full brake
boosting effect and BAS. Adaptive brake lights
The adaptive brake lights warn following traffic
in an emergency braking situation by: R flashing brake lamps
R the hazard warning lamps are activated
If you brake sharply from a speed of more than
50 km/h or if braking is assisted by BAS or BAS
PLUS, the brake lamps flash rapidly. In this way,
traffic travelling behind you is warned in an even more noticeable manner.
If you brake sharply from a speed of more than
70 km/h to a standstill, the hazard warning
lamps are activated automatically. If the brakes
are applied again, the brake lamps light up con-
tinuously. The hazard warning lamps switch off
automatically if you travel faster than 10 km/h. You can also switch off the hazard warning
lamps using the hazard warning button
(Y page 109). ESP
®
(Electronic Stability Program)
General notes i
Observe the "Important safety notes" sec-
tion (Y page 66).
ESP ®
monitors driving stability and traction, i.e.
power transmission between the tyres and the
road surface.
If ESP ®
detects that the vehicle is deviating from
the direction desired by the driver, one or more
wheels are braked to stabilise the vehicle. The
engine output is also modified to keep the vehi- cle on the desired course within physical limits.
ESP ®
assists the driver when pulling away on
wet or slippery roads. ESP ®
can also stabilise
the vehicle during braking. Driving safety systems

Important safety notes Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC shows you
the distance between your vehicle and an obsta- cle visually and audibly.
Parking Assist PARKTRONIC is only an aid. It is
not a substitute for your attention to the imme-
diate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals or
objects in range while manoeuvring and parking.
! When parking, pay particular attention to
objects above or below the sensors, such as flower pots or trailer drawbars. Parking Assist
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of the
vehicle. You could damage the vehicle or the
objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of a lorry or a pneumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
! Fold in the ball coupling if the trailer tow
hitch is not required. Parking Assist
PARKTRONIC measures the minimum detec-
tion range to an obstacle from the bumper,
not the ball coupling.
Parking Assist PARKTRONIC is activated auto-
matically when you: R switch on the ignition
R shift the transmission to position D,Ror Non
vehicles with automatic transmission
R release the electric parking brake
Parking Assist PARKTRONIC is deactivated at
speeds above 18 km/h. It is reactivated at lower
speeds.
Vehicles with a trailer tow hitch: Parking
Assist PARKTRONIC is deactivated for the rear
area when you establish the electrical connec-
tion between your vehicle and a trailer.
Range of the sensors General notes
Parking Assist PARKTRONIC does not take into
account obstacles located:
R below the detection range, e.g. persons, ani-
mals or objects
R above the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods

WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is a risk of an accident.
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you.
If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account road,
weather or traffic conditions. 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
lane.
Lane Keeping Assist does not keep your vehicle
in its lane.
The system may be impaired or may not function in the following situations:
R Poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or
spray
R Glare, e.g. from oncoming traffic, the sun or
reflection from other vehicles (e.g. if the road surface is wet)
R The windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R No or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R The lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R The distance to the vehicle in front is so small
that the lane markings cannot be detected
R The lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R The road is narrow and winding
R There are highly variable shade conditions on
the roadway
Activating Lane Keeping Assist
X Activate Lane Keeping Assist using the on-
board computer; to do so, select Standard
Standard or
Adaptive
Adaptive (Ypage 209).
If you drive at speeds above 60 km/h and lane markings are detected, the lane markings in
the assistance graphics display (Y page 208)
are shown in green. If
Standard
Standard is selected, no warning vibration
occurs if:
R You have switched on the turn signal. In this
event, the warnings are suppressed for a cer-
tain period of time.
R A driving safety system such as ABS, BAS or
ESP ®
engages.
When Adaptive
Adaptive is selected, no warning vibra-
tion occurs if:
R You have switched on the turn signal. In this
case, the warnings are suppressed for a cer-
tain period of time
R A driving safety system such as ABS, BAS or
ESP ®
engages
R You accelerate hard, e.g. kickdown
R You brake hard
R You steer actively, e.g. swerve to avoid an
obstacle or change lane quickly
R You cut the corner on a sharp bend
To ensure that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system detects certain conditions
and warns you accordingly.
The warning vibration occurs earlier in the fol-
lowing situations:
R You approach the outer lane marking on a
bend
R The road has very wide lanes, e.g. a motorway
R The system detects solid lane markings
The warning vibration occurs later in the follow- ing situations:
R The road has narrow lanes
R You cut the corner on a bend Towing a trailer
