til it engages.
Check the rear seat backrest to be
locked in its upright position
(page 267).
Once the top tether anchorage hook is
attached, the child restraint itself can be
secured. Secure the child restraint and
tighten the top tether strap according to
the child restraint manufacturer’s instruc-
tions. Child seat anchors – LATCH type
This vehicle is equipped with two LATCH
(L
ower A
nchors and T
ethers for CH
ildren)
type anchors (at each of the rear seats) for
the installation of a LATCH-type child seat
with matching mounting fittings.
Depending on vehicle production date,
your vehicle is equipped with either
LATCH-type design A or B.
iFor safety, make sure the hook2 has
attached to the anchorage ring1 be-
yond the safety catch, as illustrated.Warning!
G
Always lock backrest in its upright position
when rear seat bench is occupied by pas-
sengers, or the extended cargo area is not in
use. Check for secure locking by pushing
and pulling on the backrest.
Warning!
G
Children too big for a toddler restraint must
ride in seats using regular seat belts.
Position shoulder belt across chest and
shoulder, not face or neck.
A booster seat may be necessary to achieve
proper belt positioning for children over
41 lbs until they reach a height where a
lap/shoulder belt fits properly without a
booster.
Install child seat according to manufactur-
er’s instructions.
The child seat must be firmly attached in the
right and left side anchor1.
An incorrectly mounted child seat may come
loose during an accident which could result
in serious injury or death to the child.
Damaged or impact damaged child seats or
child seat anchor fittings must be replaced.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system.iNon-LATCH type child seats may also
be used and can be installed using the
vehicle’s seat belt system (
page 74).
Install child seat according to the
manufacturer’s instructions.

Problem
Possible cause/consequence
Suggested solution
56
The front passenger front air bag
off indicator lamp does not illu-
minate and/or does not remain
illuminated with the weight of a
typical 12-month-old child in a
standard child restraint or less
on the front passenger seat.
The system is malfunctioning.
Make sure that there is nothing be-
tween seat cushion and child seat and
check installation of the child seat.
Make sure that no objects applying
supplemental weight onto the seat
are present.
If the front passenger front air bag off
indicator lamp remains out, have the
system checked as soon as possible
by an authorized Mercedes-Benz
Center. Do not transport a child on
the front passenger seat until the sys-
tem has been repaired.
Read and observe messages in the
multifunction display and follow cor-
rective steps (
page 376).
Warning!
G
If the 56 indicator lamp does not
illuminate or remains out with the
weight of a typical 12-month-old child in a
standard child restraint or less on the front
passenger seat, do not transport a child on
the front passenger seat until the system
has been repaired.

Possible cause/consequence
Possible solution
Front passenger
air bag
activated
see Oper.’s Man.
Front passenger front air bag is
activated while driving even though
a child, small individual, or object
below the system’s weight
threshold is on the front passenger
seat, or the front passenger seat is
empty. Objects on the seat or
forces acting on the seat may
make the system sense supple-
mental weight.
Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Switch off the ignition (
page 34).
Remove child and child restraint from front passenger seat and proper-
ly secure the child in rear seat employing the child restraint if neces-
sary.
Make sure that no objects applying supplemental weight onto the seat
are present. The system may recognize such supplemental weight and
sense that an occupant on the front passenger seat is of a greater
weight than actually present.
Keep the seat unoccupied, close the front passenger door and switch
on the ignition (
page 34).

REST*
(Residual engine heat utilization)
Feature that uses the engine heat
stored in the coolant to heat the vehi-
cle interior for a short time after the en-
gine has been turned off.
Restraint systems
Seat belts, child restraints, lower an-
chors and tethers for children (LATCH).
As independent systems, their protec-
tive functions complement one anoth-
er.
Rim

(R
esearch O
ctane N
umber)
The Research Octane Number for gaso-
line as determined by a standardized
method. It is an indication of a gaso-
line's ability to resist undesired detona-
tion (knocking). The average of both
the ->MON (Motor Octane Number)
and RON (Research Octane Number) is
posted at the pump, also known as
ANTI-KNOCK INDEX.
Run Flat Indicator*
The Run Flat Indicator monitors the set
tire inflation pressures by evaluating
each wheel’s rotational speed. If a
wheel’s rotational speed changes due
to falling tire inflation pressure, a corre-
sponding warning message appears in
the multifunction display.Shift lock
When the vehicle is parked, this lock
prevents the gear selector lever from
being inadvertently moved out of
positionP without SmartKey turned
and brake pedal depressed.

Air bags, air bag control unit (with
crash sensor), emergency tensioning
device. Though independent systems,
they are closely interfaced to provide
effective occupant protection.
