belt, if available.
Alway scomply with the manufacturer'si nstal-
lation and operating instructions for the child
restraint system used.
Beforee very trip,make sure that the LATCH-
typ e(ISOFIX) chil drestraint system is engaged
correctly in both LATCH-typ e(ISOFIX) securing
rings
!Wheni nstalling the chil drestraint system,
make sure that the seatb eltf or the middle
seatd oesn ot get trapped .The seatb eltc ould
otherwise be damaged.
XInstal lthe LATCH-typ e(ISOFIX) chil drestraint
system on both LATCH-typ e(ISOFIX) securing
rings :.
ISOFIX is astandardized securing system for
speciall ydesigne dchildr estraint systems on
the rears eats. LATCH-typ e(ISOFIX) securing
ring sfor two LATCH-typ e(ISOFIX) chil drestraint
systems are installed on the left and right of the
rears eats.
Non-LATCH-typ e(ISOFIX) chil dseats may also
be used and can be installed using the vehicle's
seatb elts ystem. Instal lthe chil dseata ccording
to the manufacturer'si nstructions.
Top Tether
Introduction
Top Tether provides an additiona lconnection
between the chil drestraint system secured with
aL ATCH-typ e(ISOFIX) system and the vehicle.
Thish elps reduce the ris kofinjury evenf urther.
If the chil drestraint system is equipped with a
Top Tether belt, this shoul dalway sbeu sed.
Important safety notes
GWARNING
If the rears eatbackrests are not locked, they
could foldf orwardsinthe event of an acci-
dent, heavy braking or sudde nchanges of
direction. As aresult, chil drestraint systems
cannot perform theiri ntended protective
function. Rear seatb ackrests that are not
locke dcan also cause additiona linjuries, e.g.
in the event of an accident. Thisp oses an
increase driskofi njury or evenf atalinjury.
Alway slock rears eatbackrests afte rinstal-
ling aTop Tether belt. Adjus tthe rears eat
backrests so that they are in an upright posi-
tion.
Make sure that the backrest in the rearc om-
partment engages fully .Todoso, pull firmly on
the seatb ackrest.

Safety

GWARNING
If you secure achild in aforward-facing child
restraint system on the front-passenge rseat
and you position the front-passenge rseat too
close to the dashboard, in the event of an
accident, the child could:
Rcome into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
Rbe struck by the air bag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Move the front-passenge rseat as far back as
possible.A lways make sure that the shoulder
belts trap is correctly routed from the vehicle
belts ash guide to the shoulderb eltguide on
the child restraint system. The shoulderb elt
strap must be routed forwards and down-
wards from the belts ash guide. If necessary,
adjust the belts ash guide and the front-
passenger seat accordingly.A lways observe
the information about suitable positioning of
the child restraint system in this Operator's
Manual as wellast he child restraint system
manufacturer's installation instructions.
PASSENGER AIR BAG OFF indicator lamp :
showsy ou whethert he front-passenge rfront air
bag is deactivated.
XTurn the SmartKey to position 1or 2in the
ignitio nlock.
The system carrie sout self-diagnostics.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds. If, after the system self-test, the
PASSENGER AI
RBAG OFF indicator lamp:
Ris lit:t he front-passenge rfront air bag is
deactivated. It wil lthen not be deploye dinthe
event of an accident.
Ris not lit :the sensor system did not detect a
child restraint system with transponde rfor
the BabySmart™ air bag deactivation system.
If, in the event of an accident, all deployment criteria are met, the front-passenge rfront air
bag is deployed.
Childr estraint system on the front-
passenger seat
General notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenge rseat. For this reason,
Mercedes-Benz strongly advises that you install
the child restraint system on arear seat.
If it is absolutel ynecessary to install achild
restraint system on the front-passenge rseat,
alway sobserve the information on the "Baby-
Smart™ air bag deactivation system"
(
Ypage5 3).
You can thus avoi dthe risks that coul darisea s
ar esult of:
Rac hild restraint system that is not detected
by the BabySmart™ air bag deactivation sys-
tem sensor system
Rthe unintentional deactivation of the front-
passenger front air bag
Rthe unsuitabl epositioning of the child
restraint system, e.g. too close to the dash-
board
Rearward-facin gchildr estraint system
If it is absolutel ynecessary to install arearward-
facing child restraint system on the front-
passenger seat, alway smake sure that the
front-passenge rfront air bag is deactivated.
Only if the PASSENGER AIR BAG OFF indicator
lamp is permanently lit (
Ypag e39) is the front-
passenger front air bag deactivated.
Always observe the child restraint system man-
ufacturer's installation and operating instruc-
tions.

Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
There is arisk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
If you attach heavy or large object stothe
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large object stothe
SmartKey. Remove any bulky key rings before
insertingt he SmartKey into the ignition lock.
!Keep the SmartKey away from stron gmag-
netic fields. Otherwise, the remote control
function could be affected.
Strong magnetic fields can occur in the vicin-
ity of powerful electrical installations.
Do not keep the SmartKey:
Rwith electronic devices, e.g. amobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. ametal case.
This can affect the functionality of the Smart- Key. Ac
heck which periodically establishes aradio
connection between the vehicle and the Smart-
Key determines whether avalid SmartKey is in
the vehicle. This occurs, for example:
Rwhen startin gthe engine
Rwhile driving

XTo unlock centrally: press the%button.
If you do not open the vehicle within approx-
imately 40 seconds of unlocking:
Rthe vehicle is locked again.
Rprotection against theft is reactivated.
XTo lock centrally: press the&button.
The turn signals flash once when unlocking and
three times when locking.
You can also set an audible signal to confirm
that the vehicle has been locked. The audible
signal can be activated and deactivated using
the on-board computer (
Ypage 166).
You will receive visual and acoustic locking con-
firmation if all components were able to be
locked.
When the surround lighting is activated via the
on-board computer, it lights up when it is dark
after the vehicle is unlocked with the SmartKey (
