Occupant safety
51move the front-passenger seat to its rear-
most position.
R have the automatic child seat recognition
checked at a qualified specialist work-
shop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions correctly, never place objects (such
as a cushion) under the child restraint sys-
tem. The entire base of the child restraint
system must always rest on the seat cush-
ion. An incorrectly fitted child restraint sys-
tem cannot perform its intended protective
function in the event of an accident, and
could lead to injuries. i
The windowbag, the sidebag and the belt
tensioner on the front-passenger side are
still active even when the front-passenger
front airbag is disabled. G
Risk of injury
Do not place items of electronic equipment
on the front-passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes
or access cards
Signals from electronic equipment can
cause interference in the automatic child
seat recognition sensor system. This could lead to a system malfunction. This may
cause the
5PASSENGER AIRBAG OFF
warning lamp to light up without there
being a child seat with automatic child seat
recognition fitted. This means that the
front-passenger airbag does not deploy
during an accident. It is also possible that
the 5 PASSENGER AIRBAG OFF warning
lamp will not light up briefly if you turn the
key in the ignition lock to position 2.

If the interior motion sensor is primed, a vis-
ual and audible alarm is deployed if move-
ment is detected in the vehicle interior while
the vehicle is locked. This occurs, for exam-
ple, if someone breaks the side windows of
your vehicle or reaches into the vehicle's inte-
rior.
Priming the interior motion sensor X
Make sure that: R
the side windows are closed
R the sliding/tilting sunroof* is closed
R there are no objects, e.g. mascots, hang-
ing on the rear-view mirror or on the
grasp handles on the roof trim.
This will prevent false alarms.
X Make sure that all the doors and the tail-
gate are closed.
X Lock the vehicle with the key or, on vehicles
with KEYLESS GO*, with the locking button
on the door handle.
The interior motion sensor is primed after
approximately 40 seconds.
Deactivating the interior motion sensor To prevent a false alarm, deactivate the inte-
rior motion sensor if you lock your vehicle and

It is possible to deactivate the interior motion
sensor using the on-board computer for the
next time the vehicle is locked
(Y page 134). The interior motion sensor
remains deactivated until you unlock and lock
the vehicle again. If you select
Interior motion sensor in

tion contained in the Vehiclesubmenu,

approximately six seconds until the battery
check lamp flashes twice.

X To unlock the driver's door: press the
k button once.
X To unlock centrally: press thekbut-
ton twice.
X To lock centrally: press thejbutton.
Restoring the factory settings X
Press the kandj buttons simulta-
neously for approximately six seconds until
the battery check lamp flashes twice. KEYLESS GO*
The optional equipment supplied with your
vehicle includes two KEYLESS GO keys. You
can start, lock or unlock the vehicle using the
KEYLESS GO key. To do this, you need only
carry the KEYLESS GO key on your person.
When you touch the surface of the sensors on
the vehicle's door handles, KEYLESS GO
establishes a radio connection between the
vehicle and the key. The distance between
the KEYLESS GO key and the vehicle's door
handle from which you wish to lock or unlock
the vehicle, must not be greater than 1 m.
When you pull the door handle, the following
unlock centrally if the factory settings have
not been changed:
R the doors
R the tailgate
R the fuel filler flap
If you pull on the handle of the tailgate, only
the tailgate of your vehicle is unlocked.
When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid
KEYLESS GO key is in the vehicle by periodi-
cally establishing radio contact. G
Risk of accident
If children are left unsupervised in the vehi-
cle, they could open a door from the inside,
even if it has been locked. Or they could
start the vehicle if a valid KEYLESS GO key
is in the vehicle and they press the KEY-
LESS GO button on the ignition lock. They
could endanger themselves and others.
Never leave children unsupervised in the
vehicle. Switch off the engine and take the
KEYLESS GO key with you, even if you are
only leaving the vehicle for a short time. 1

Folding the exterior mirrors in or out
electrically* 1
To fold the exterior mirrors in or out
X Make sure that the key is in position 1or
2 in the ignition lock.
X Briefly press button 1.
Both exterior mirrors fold in or out.
i Make sure that the exterior mirrors are
always folded out fully while the vehicle is
in motion; otherwise, they may vibrate. Resetting the exterior mirrors If the battery has been disconnected or has
become discharged, the exterior mirrors
must be reset. If this is not done, the exterior
mirrors will not fold in when you select the
"Fold in mirrors when locking" function in the
on-board computer (Y
page 133).
X Make sure that the key is in position 1in
the ignition lock.
X Briefly press button 1.
Folding the exterior mirrors in or out
automatically* If the "Fold in mirrors when locking" function
is activated in the on-board computer
(Y
page 133),
R the exterior mirrors fold in automatically as
soon as you lock the vehicle from the out-
side
R The exterior mirrors fold out again auto-
matically as soon as you unlock the vehicle
and then open the driver's or front-
passenger door.
i If you have activated this function and fold
in the exterior mirrors using button 1, they
will not be folded out automatically. You can then only fold out the exterior mirrors
using button
1. Automatic anti-dazzle mirrors*
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
dazzle mode if the ignition is switched on and
incident light from headlamps strikes the sen-
sor in the rear-view mirror.
The mirrors do not go into anti-dazzle mode if
reverse gear is engaged or the interior lighting
is switched on. G
Risk of accident
If incident light from headlamps cannot
strike the sensor in the rear-view mirror, for
instance if the safety net is fitted, the mir-
ror's automatic anti-dazzle function will not
work.
Incident light could then dazzle you. This
may distract you from the traffic conditions,
and you may thereby cause an accident. In
this case, adjust the rear-view mirror man-
ually. Controls

Selecting the switch-on time for the

has an auxiliary heating system.
The
Auxiliary heating function allows you
to select three switch-on times. You can set
the exact switch-on time using the other func-
tions in the Heatersubmenu.
You can switch off the auxiliary heating by
using the remote control or the auxiliary heat-
ing button on the centre console.
The auxiliary heating is switched off automat-
ically after 50 minutes. This time can be
changed. To do this, visit a qualified specialist
workshop, e.g. a Mercedes-Benz Service
Centre. G
Risk of poisoning
Exhaust fumes are produced when the aux-
iliary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You
should therefore switch off the auxiliary heating in confined spaces without an
extraction system, e.g. a garage.
G
Risk of fire
When operating the auxiliary heating, parts
of the vehicle may become very hot, and
highly inflammable material such as fuels
could be ignited. Operating the auxiliary
heating is thus prohibited at filling stations
or when your vehicle is being refuelled. You
must therefore switch off the auxiliary heat-
ing at filling stations.
You can call up the Auxiliary heating.
