WARNING
If you leave children unattended in the vehi-
cle, they may be abletos et the vehiclein

R release the parking brake
R shift the automatic transmission out of park
position Por shift manua ltransmission into
neutral
R start the engine
In addition, they may operate vehicl eequip-
ment and become trapped. There is arisk of
an accident and injury.
When leaving the vehicle, alwayst ake the key
with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If persons (particularly children) are exposed
to heatorc old foraprolonged period, there is
ar isk of serious or even fatal injuries. Never
leave persons (particularly children) unatten-
ded in the vehicle. G
WARNING
If the child restraint system is placed in direct sunlight, the parts coul dbecome very hot.
Childre ncouldbes uffer burns by touching
these parts, in particular on the metallic parts
of the child restraint system. There is arisk of
injury.
If you and yourc hild leave the vehicle, always
make sure that the child restraint system is
not in direct sunlight. Cove ritwithablanket,
for example. If the child restraint system has
been expose dtodirect sunlight, leave it to
cool downb efore securing the child in it.
Never leave children unattended in the vehi-
cle.
Always ensure that all vehicl eoccupants have
their seat belts fastened correctly and are sitting
properly.P articular attention must be paidto
children.
Observe the safety notes on the seat belt
(Y page4 1) and the notes on how to use the seat
beltp roperly (Y page42). Chil

Observe the instructions for correct use of the
child restraint system (Y page60).
For safety reasons, Mercedes-Benz recom-
mends that you only use achild restraint system
recommende dbyMercedes-Benz
(Y page6 4). G
WARNING
If the child restraint system is incorrectly fit-
ted on the seat position suitable for this pur-
pose, it cannot perform its intended protec-
tive function. In the event of an accident,
sharp braking or asudden change in direction,
the child may not be held securely.T here is an
increased risk of serious or even fatal injuries.
Observe the manufacturer's installation
instructions and the correct use for the child
restraint system. Make sure that the entire
surface of the child restraint system is resting
on the seat surface. Never place objects
under or behind the child restraint system,
e.g. cushions. Only use child restraint sys-
tems with the original cover designed for
them. Only replace damaged covers with gen- uine covers. G
WARNING
If the child restraint system is fitted incor-
rectly or is not secured, it can come loos ein
the event of an accident, heav ybraking or a
sudden change in direction. The child
restraint system coul dbethrown about, strik-
ing vehicl eoccupants. 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.

If the rear seat backrests are not locked, they
could fold forward sinthe event of an acci-
dent, heavy braking or sudden changes of

the following driving safety systems:

R STEERC ONTROL (Y page 77) Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front,f or vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and
weather condition sand maintain asafe distance
from the vehicle in front.D rive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tyres and the road
surface. Pay particular attention to the informa- tion regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and tyres" section (Y page 353).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. ABS (Anti-loc
kBraking System)
General notes ABS regulates brake pressure in such
away that
the wheels do not lock when you brake. This
allowsy ou to continue steering the vehicle when
braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from aspeed of about 8km/h,
regardless of road-surface conditions. ABS
works on slippery surfaces, even when you only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristic smay be severely impaired. Addition-

tions.
In such cases, Adaptiv eBrakeA ssist can:
R interven eunnecessarily
R not intervene
There is arisk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the

WARNING
Adaptiv eBrakeA ssist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As aresult, the Adaptiv eBrak eAssist may not

risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
Due to the natur eofthe system, particularly
complicated but non-critical driving conditions
may also cause Brak eAssist to intervene.
If Adaptiv eBrak eAssist is not available due to a
malfunction in the radar sensor system, the
brake system remains available with full brake

Crosswind Assist General notes
Strong crosswind gusts can impair the road-

WARNING
If EBD is malfunctioning, the rear wheelsc an
lock, e.g. under full braking. This increases the risk of skidding and an accident.
You shouldt herefore adapt yourd riving style
to the different handling characteristics. Have the brake system checked at
