Diagnostics connection
The diagnostics connection is used for connect- ing diagnostic equipment at a qualified special-
ist workshop. G
WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it may affect the
operation of vehicle systems. As a result, the operating safety of the vehicle could be affec-
ted. There is a risk of an accident.
Only connect equipment to a diagnostics con-
nection in the vehicle, which is approved for
your vehicle by Mercedes-Benz. G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor- mats on top of one another.
! If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor-
mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of
the next emissions test during the main inspec- tion. Qualified specialist workshop
A qualified specialist workshop has the neces-
sary special skills, tools and qualifications to
correctly carry out any necessary work on your
vehicle. This particularly applies to work rele-
vant to safety.

M
MSolutions The PASSENGER AIR
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 42).
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
BAG OFF indicator lamp
does not light up and/or
does not stay on.
The front-passenger seatis:
R empty
R occupied with a rear-
ward-facing child
restraint system The automatic front-passenger front airbag deactivation system is
malfunctioning.
X Make sure there is nothing between the seat and the child restraint
system.
X Make sure that the entire base of the child restraint system rests on
the seat cushion of the front-passenger seat.
X When installing the child restraint system, make sure that the seat
belt is tight. Do not pull the seat belt tight with the front-passenger
seat adjustment. This could result in the seat belt and the child
restraint system being pulled too tightly.
X Check that the child restraint system is installed correctly.
X Make sure that no objects are applying additional weight to the
seat.
X If the PASSENGER AIR BAG OFF indicator lamp remains off and/or
the PASSENGER AIR BAG ON indicator lamp lights up, do not install
a rearward-facing child restraint system on the front-passenger
seat.
X Have the automatic front-passenger front airbag deactivation sys-
tem checked immediately at a qualified specialist workshop. Deployment of belt tensioners and air-
bags
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 transported to a qualified specialist
workshop after an accident. Take this into
account, particularly if a seat belt tensioner was
triggered or an airbag was deployed. Observe
the notes on towing the vehicle away
(Y page 256).
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
amount of powder may also be released. The
6 restraint system warning lamp lights up. 46

G
WARNING
If the child restraint system is fitted incor-
rectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, strik- ing vehicle occupants. There is an increased
risk of injury, possibly even fatal.
Always fit child restraint systems properly,
even if they are not being used. Make sure
that you observe the child restraint system
manufacturer's installation instructions.
Further information on stowing objects, luggage and loads securely can be found under "Loading
guidelines" (Y page 217). G
WARNING
Child restraint systems or their securing sys-
tems that have been damaged or subjected to a load in an accident cannot perform their
intended protective function. In the event of
an accident, sharp braking or a sudden
change in direction, the child may not be held securely. There is an increased risk of serious
or even fatal injuries.
Immediately replace child restraint systems
that have been damaged or subjected to a
load in an accident. Have the child restraint
securing systems checked in a qualified spe-
cialist workshop before fitting a child restraint
system again.
The seat belt system serves as the securing sys- tem for child restraint systems.
If you fit a child restraint system to the front-
passenger seat, be sure to observe the informa-
tion on "Child restraint systems on the front-
passenger seat" (Y page 50). Information on
disabling the front-passenger front airbag can
also be found there.
Observe the warning labels in the vehicle inte-
rior and on the child restraint system.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems rec-
ommended by Mercedes-Benz. Information
can be obtained at a qualified specialist work-
shop. Child restraint system on the front-
passenger seat
General notes Vehicles with the automatic front-
passenger front airbag deactivation system:
if you fit a child restraint system to the front-
passenger seat, always observe the information
on the "Automatic front-passenger front airbag
deactivation system" (Y page 41).
You can thus avoid the risks that could arise as a result of:
R a child restraint system that is not detected
by the automatic front-passenger front airbag
deactivation system
R unintentional disabling of the front-passenger
front airbag
R unsuitable positioning of the child restraint
system, e.g. too close to the dashboard Please observe the warning notice on the
front-passenger sun visor; see illustration. 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.
NEVER use a rearward-facing child restraint on a
seat protected by an ACTIVE AIRBAG in front of it; DEATH or SERIOUS INJURY to the child can
occur. 50

Important safety notes
G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open. G
WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, especially when braking or abruptly changing directions.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
! The tailgate swings upwards and out when
opening. Therefore, make sure that there is
sufficient space above the tailgate.
The opening dimensions of the tailgate can be
found in the "Vehicle data" section
(Y page 281).
If the rear spoiler has been extended manually,
the height when opened is higher by this
amount. If in doubt, retract the rear spoiler again manually before opening the tailgate
(Y page 224).
You can switch the luggage compartment light-
ing on and off manually on the overhead control
panel (Y page 91).
Do not leave the key in the luggage compart-
ment. You could otherwise lock yourself out.
