belt, a windowbag may be deployed in other
accident situations (Y page 51).Automatic front-passenger front air-
bag deactivation
Introduction In order to recognise a child restraint system on
the front-passenger seat, the automatic front-
passenger front airbag deactivation system cat- egorises the person in the front-passenger seat.Depending on that result, the front-passenger
front airbag is either enabled or disabled. If a
rearward-facing child restraint system is fitted
to the front-passenger seat, the PASSENGER
AIR BAG OFF indicator lamp must light up after
the system self-test and remain lit. The front-
passenger front airbag is disabled.
The system does not disable:
R the sidebag
R the windowbag
R the seat belt tensioner
Make sure that your vehicle is equipped with the automatic front-passenger front airbag deacti-
vation system (Y page 57). If this is not the
case, always install a child restraint system on a
suitable rear seat (Y page 59).
If it is absolutely necessary to install a child
restraint system on the front-passenger seat, be sure to observe the correct positioning of the
child restraint system. Never place objects
under or behind the child restraint system, e.g. a
cushion. 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 a forward-
facing child restraint system must, as far as
possible, rest flat against the backrest of the
front-passenger seat. The child restraint system must not touch the roof or be put under strain bythe head restraint. Adjust the angle of the seat
backrest and the head restraint position accord-
ingly. Only then is the correct function of the
automatic front-passenger front airbag deacti-
vation system guaranteed. Always observe the
information on suitable positioning of the child
restraint system (Y page 59) in addition to the
child restraint system manufacturer's installa-
tion instructions. Operation of automatic front-passenger
front airbag deactivation :
PASSENGER AIR BAG ON indicator lamp
; PASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether the
front-passenger front airbag is disabled or ena-
bled.
X Press the Start/Stop button once or twice, or
turn the key to position 1or 2in the ignition
lock.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul- taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front airbag:
R PASSENGER AIR BAG ON lights up for 60 sec-
onds, then both indicator lamps are off
(PASSENGER AIR BAG ON and OFF): the front-
passenger front airbag is able to deploy in the
event of an accident.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger
front airbag. The PASSENGER AIR BAG OFF indi-
cator lamp may be lit continuously or be off.
If the status of the front-passenger front airbag
changes while the vehicle is in motion, an airbag display message appears on the instrument
cluster (Y page 226). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger front
airbag both before and during the journey. Occupant safety
47Safety Z

If a person sits in the passenger seat, he/she
must be:
R seated with the seat belt fastened correctly
R in an almost upright position with his/her
back against the seat backrest
R with his/her feet resting on the floor, if pos-
sible
If the front passenger does not observe these
conditions, the automatic front-passenger front
airbag deactivation system may be influenced,
e.g. because the front passenger:
R transfers his/her weight by supporting him-
self/herself on a vehicle armrest
R sits in such a way that his/her weight is raised
from the seat cushion
The front-passenger front airbag may be disa-
bled by mistake as a result of these or similar
actions. In this case, the PASSENGER AIR BAG
OFF indicator lamp lights up permanently. The
front-passenger front airbag then does not
deploy during an accident. G
WARNING
If the PASSENGER AIRBAG OFF indicator lamp is lit, the front-passenger front airbag is disa-
bled. It will not be deployed in the event of an
accident and cannot perform its intended pro-
tective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always make sure that:
R the classification of the person in the front-
passenger seat is correct and that the front-
passenger front airbag is enabled or disa-
bled in accordance with the person in the
front-passenger seat.
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front airbag is correct. G
WARNING
If you secure a child in a rearward-facing child
restraint system on the co-driver's seat and
the PASSENGER AIR BAG OFF indicator lamp
is off, the co-driver's front airbag can deploy in the event of an accident. The child could be
struck by the airbag. There is an increased risk
of injury, possibly even fatal.
In this case, always make sure that the co-
driver's front airbag has been disabled. The
PASSENGER AIR BAG OFF indicator lamp
must be lit.
If the PASSENGER AIR BAG OFF indicator lamp
stays off, do not install a rearward-facing child
restraint system on the front-passenger seat.
Further information can be found under "Prob-
lems with the automatic front-passenger front
airbag deactivation system" (Y page 50). G
WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the airbag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Always move the front-passenger seat as far
back as possible and fully retract the seat
cushion length. 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 shoul-
der 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 about suitable posi-
tioning of the child restraint system in this
Owner's Manual as well as the child restraint 48

BAG OFF indicator lamp
lights up and remains lit,
even though the front-
passenger seat is occu-
pied by an adult or a per-
son with a build corre-
sponding to that of an
adult. The classification of the person on the front-passenger seat is false.
X Make sure the conditions for a correct classification of the person
on the front-passenger seat are met (Y page 47).
X If the PASSENGER AIR BAG OFF indicator lamp remains lit, the front-
passenger seat may not be used.
X Have the automatic front-passenger front airbag deactivation sys-
tem checked immediately at a qualified specialist workshop. The PASSENGER AIR

Important safety notes G
WARNING
After the airbag deploys, the airbag parts are
hot. There is a risk of injury.
Do not touch the airbag parts. Have a
deployed airbag replaced at a qualified spe-
cialist workshop as soon as possible. G
WARNING
Pyrotechnical belt tensioners which have
been triggered are no longer operational and therefore cannot protect as intended. There is
an increased risk of injury, possibly even fatal.
Have pyrotechnic belt tensioners which have
been triggered replaced at a qualified special-
ist workshop immediately.
Mercedes-Benz recommends that you have the
vehicle towed to a qualified specialist workshop
after an accident. Take this into account, par-
ticularly if a seat belt tensioner was triggered or
an airbag was deployed.
An electric motor is used by PRE-SAFE ®
to trig-
ger the tightening of the seat belt in hazardous
situations. This procedure is reversible.
If the belt tensioners are triggered or an airbag is
deployed, you will hear a bang, and a small Occupant safety

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
child restraint systems
R Suitability of the seats for attaching an i-Size

X Move the front-passenger seat as far back as
possible and fully retract the seat cushion
length.
If you secure a child in a forward-facing child
restraint system on the front-passenger seat,
you must also move the front-passenger seat to the highest position.
X Move the backrest to an almost vertical posi-
tion.
The entire base of the child restraint system
must always rest on the seat cushion of the front-passenger seat. The backrest of the
forward-facing child restraint system must, as far as possible, be resting on the backrest of
the front-passenger seat. The child restraint
system 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 position accordingly. Also observe
the child restraint system manufacturer's
installation instructions.
X If possible, move the seat cushion angle to the
highest, most vertical position (Y page 98).
Suitability of the seats for attaching a belt-secured child restraint system If you use a baby car seat of category 0 or 0+ or a rearward-facing child restraint system of category
I on a rear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch the child restraint system.
If you use a category I, forward-facing child restraint system, you should remove the head restraintfrom the respective seat, if possible (Y page 100). The backrest of the child restraint system must,
as far as possible, lie flat against the backrest of the seat.
Make sure that the child's feet do not touch the front seat. If necessary, move the front seat forward
slightly.
For certain child restraint systems in weight categories 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.
Always observe the notes in the "Child restraint system" section (Y page 54) and the child restraint
system manufacturer's installation instructions.
When you remove the child restraint system, you must replace the head restraints again immedi-
ately (Y page 99). All vehicle occupants must adjust their head restraints correctly before begin-
ning the journey.

ParkingDriving and pa
rking

Parking tips:
R on narrow roads, drive as closely as possible
past the parking space
R parking spaces that are littered or overgrown
might be identified or measured incorrectly
R parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly
R snowfall or heavy rain may lead to a parking
space being measured inaccurately
R pay attention to the Parking Assist
PARKTRONIC warning messages
(Y page 178) during the parking procedure
R you can intervene in the steering procedure to
correct it at any time. Parking Pilot will then be cancelled
R when transporting a load that protrudes from
your vehicle, you should not use Parking Pilot
R never use Parking Pilot when snow chains are
fitted
R make sure that the tyre pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle
Use Parking Pilot for parking spaces that are:
R parallel or at right angles to the direction of
travel
R on straight roads, not bends
R on the same level as the road, e.g. not on the
pavement
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached a trailer to your vehicle, you
should not use Parking Pilot. Once the electrical
connection is established between your vehicle
and the trailer, Parking Pilot is no longer availa- ble. Parking Assist PARKTRONIC is deactivated
for the rear area.
Detecting parking spaces Objects located above the detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking procedure is calcula- ted, e.g. overhanging loads, tail sections or load-
ing ramps of goods vehicles. G
WARNING
If there are objects above the detection range:
R Parking Pilot may steer in too early
R the vehicle may not stop in front of these
objects
This could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop and deactivate Parking Pilot.
Further information on the detection range
(Y page 177).
Parking Pilot does not assist you parking in
spaces at right angles to the direction of travel if:
R two parking spaces are located directly next
to one another
R the parking space is directly next to a low
obstacle such as a low kerb
R you forward-park
Parking Pilot does not assist you parking in
spaces parallel or at right angles to the direction of travel if:
R the parking space is on a kerb
R the system reads the parking space as being
blocked, such as by foliage or grass paving
blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obstacle,

General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect them at all. The system is not a substitute for a well-rested and
attentive driver.
