The Emergency Tensionin gD evice tighten st he
seat belt in an accident ,p ulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest.
The Emergency Tensionin gD evice does not cor-
rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, as eat belt force limiter helps to
reduce the force exerted by the seat belt on the
vehicle occupant.
The seat belt force limiters are synchronized
with the front air bags which absorb part of the
deceleration force. This can reduce the force
exerted on the vehicle occupant sd uring an acci-
dent.
! If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of
the front-passenger seat. This may otherwise
lead to the triggerin goft he Emergency Ten-
sioning Device in the event of an accident,
which will then need to be replaced.
Important safety notes The use of seat belts and child restraint systems
is required by law in: R
all 50 states R
the U.S. territories R
the District of Columbia R
all Canadian provinces
Even where this is not required by law, all vehicle
occupant ss hould correctly fasten their seat
belts before starting the journey.
G WARNING
If the seat belt is not worn correctly, it cannot
perform its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of injury
or even fatal injury.
Always ensure that all vehicle occupant sh ave
their seat belts fastened correctly and are sit-
ting properly.
G WARNING
The seat belt does not offer the intended level
of protection if you have not moved the back- rest to an almost vertical position. When brak-
ing or in the event of an accident ,y ou could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
G WARNING
Persons less than 5ft( 1.50 m) tall cannot
wear the seat belt correctly without an addi-
tional and suitable restraint system. If the
seat belt is not worn correctly, it cannot per-
form its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of injury
or even fatal injury.
For this reason, alway ss ecure persons under
5ft( 1.50 m) tall in suitable additional restraint
systems.
If ac hild younger than twelve years old and
under 5ft( 1.50 m) in height is traveling in the
vehicle: R
alway ss ecure the child in ac hild restraint
system suitable for this Mercedes-Benz vehi-
cle. The child restraint system must be appro-
priate to the age, weight and size of the child R
alway so bserve the instructions and safety
notes on "Children in the vehicle"
( Y
page 51) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions R
be sure to observe the instructions and safety
notes on the "Occupant classification system
(OCS)" ( Y
page 44)Occupant safety 39
Safety Z

instructions and safet yn otes on the "Occupant
Classification System (OCS)" ( Y
page 44).
You can thus avoid the risk st hat could arise as
ar esult of: R
an incorrectly categorized perso nint he front-
passenger seat R
the unintentional deactivatio noft he front-
passenger front air bag R
the unsuitable positionin goft he child
restraint system, e.g. too clos etot he dash-
board
Rearward-facing child restraint system If it is absolutely necessary to install ar earward-
facin gc hild restraint system on the front-
passenger seat, always make sure that the
front-passenge rf ront air bag is deactivated.
Only if the PASSENGER AI RB AG OFF indicator
lamp is permanently lit ( Y
page 38) is the front-
passenger front air bag deactivated.
Always observe the child restraint system man-
ufacturer' si nstallation and operating instruc-
tions.
Forward-facing child restraint system If you secur eac hild in af orward-facin gc hild
restraint system on the front-passenge rs eat,
always move the front-passenge rs eat as far
back as possible .T he entire base of the child
restraint system must always rest on the seat
cushio noft he front-passenge rs eat. The back-
rest of the child restraint system must lie as flat
as possible against the backrest of the front-
passenger seat. The child restraint system must
not touc ht he roof or be subjected to al oad by
the head restraint .A djust the angle of the seat
backrest and the head restraint position accord-
ingly. Always make sure that the shoulder belt
strap is correctly routed fro mt he front-
passenger seat belt loop to the shoulder belt
guide on the child restraint system. The shoul-
der belt strap must be routed forwards and
downwards fro mt he front-passenge rs eat belt
loop.
Always observe the child restraint system man-
ufacturer' si nstallation and operating instruc-
tions. Pets in th ev ehicle

good time, and for staying in lane. Always adapt
your driving style to suit the prevailing road and
weather conditions and maintain as afe distance
from the vehicle in front .D rive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and tires"
section ( Y
page 255).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
General information ABS regulates brake pressure in such aw ay 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 as peed of about 5m ph
(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 54).
G WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally ,f urther 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 aq ualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp ( Y
page 204) and dis- play messages which may be shown in the
instrument cluster ( Y
page 179).
Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over. X
To make af ull 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, and functions as a
reminder to take extr ac are while driving.
BAS (Brake Assist System)
General information BAS operates in emergenc yb raking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
i Observe the "Important safety notes" sec-
tion ( Y
page 54).
G WARNING
If BAS is malfunctioning, the braking distance
in an emergenc yb raking situation is
increased. There is ar isk of an accident.
In an emergenc yb raking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking X
Keep the brake pedal firmly depressed until
the emergenc yb raking situation is over.
ABS prevent st he wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.Driving safety systems 55
Safety Z

! When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. 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 on at ruck
or ap neumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automaticall yw hen

mals or objects. R
above the detection range, e.g. overhanging
loads, truck overhangs or loading ramps.
C
Sensors in the front bumper, left-hand side
