move the front-passenger seat to the rear-
most position.
R have the automatic child seat recognition
checked at aqualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. acushion, under the child
restraint system. The entire base of the child
restraint system must alwaysr est on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could leadtoi njuries.
i If the front-passenger airbag is disabled
by the automatic child seat recognition, the
following remai nenable dont he front-
passenge rside:
R the sidebag
R the pelvisbag
R Cabriolet :the headbag
R Coupé:t he windowbag
R the belt tensioner G
WARNING
Do not place electronic devices 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 rec-
ognition sensor system. This can lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF indicator
lamp to light up without there being achild
seat with transponders for automatic child
seat recognition fitted. The front-passenger
airbag will not then deploy during an accident.
It is also possible that the 6SRS warning
lamp lights up and/or the 4PASSENGER
AIRBAG OFF indicator lamp does not light up briefly when you turn the key in the ignition
lock to position 2.
ISOFIXc hild seat securing system for
the rear seats ISOFIXisas
tandardised securing system for
specially designed child restraint systems on
the rear seats. Securing rings for two ISOFIX
child restraint systems are fitted on the left
and right of the rear seats.
Mercedes-Ben zrecommends the use of ISO-
FIX child restraint systems listed on
(Y page 59) together with the insertion
guides included. Using insertion guides
makes it easier to fit ISOFIXc hild restraint
systems. G
WARNING
Ac hild restraint system secured by the ISOFIX
child seat securing system does not provide
sufficient protection for children weighing
more than 22 kg. For this reason, do not
secure children weighing more than 22 kg in
ac hild restraint system secured by the ISOFIX
child seat securing system. If the child weighs
more than 22 kg, secure the child restraint
system using athree-point seat belt. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to as uitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudden changes of direction. The
child could be seriously or even fatally injured.
For this reason, when fittingac hild restraint
system, observe the manufacturer's installa-
tion instructions and the correct use of the
child restraint system.
For reasons of safety, only use child restraint
systems with the ISOFIX child seat securing
system on the rear seats.
We recommendt hat you use the ISOFIX child
restraint systems that have been recommen-
ded for Mercedes-Benz. 54

AIRBAGO FF indicator
lamp on the centre con-
sole is lit. As
pecial Mercedes-Benz child seat with atransponder for auto-
matic child seat recognition has been fitted to the front-passenger
seat. The front-passenger airbag has therefore been disabled as
desired. G
Risk of injury
There is no child seat fitted to the front-passenger seat. Automatic
child seat recognition is malfunctioning.
It is also possible that the 6SRS warning lamp lights up and/
or the 4PASSENGER AIRBAG OFF indicator lamp does not light
up briefly when you switc hthe ignition on.

WARNING
The risk of an acciden tissignificantly
increased by driving too fast. This is particu-
larly the case when cornering as well as on
wet or slippery roads or when driving too close
to the vehicle in front.
The driving safety systems described in this
section can neither reduce this risk nor over-
ride the laws of physics.
For this reason, always adapty our driving
style to the prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and object sonthe road.
i Please notet hat the driving safety sys-
tems described only work as effectively as
possible when there is adequate contact
between the tyres and the road surface.
Pay particular attention to the information
regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and
tyres" section (Y page 318). Driving safety systems

or BAS PLUS, the brake lamps flash rapidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from aspeed of more
than 70 km/htoa standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automaticallyify ou travel
faster than 10 km/h .You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 117).ESP
®
(Electronic Stability Program)
Important safety notes i
See the "Important safety notes" section
(Y page 61).
If ESP ®
detect sthat the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
If ESP ®
intervenes, the ÷ESP®
warning
lamp flashes in the instrument cluster. G
WARNING
If the ÷ warning lamp in the instrument
cluster flashes, proceed as follows:
R do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt your driving style to suit the prevail-
ing road and weather conditions.
Otherwise, the vehicle could go into askid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics. !
Switch the ignition off when:
R the parking brake is being tested using a
dynamometer
R the vehicle is being towed with the front/
rear axle raised
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS (Electronic Traction Support) Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
viduall yifthey spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side.
Traction control remains active if you deacti-
vate ESP ®
. G
WARNING
Traction control cannot reduce the risk of an
accident if you drive too fast. Traction control
cannot override the laws of physics.
Deactivating/activating ESP ® i
Observe the "Important safety notes" sec-
tion (Y page 61).
ESP ®
is activated automatically when the
engine is started.
i Vehicles with ECO start/stop function:
the ECO start/stop function switches the
engine off automatically when the vehicle
comes to astop. The engine startsa uto-
matically when the driver wants to pull
away again. ESP ®
remains in its previously
selected status. Example: if ESP ®
was
deactivated before the engine was
switched off, ESP ®
remains deactivated
when the engine is switched on again. 64
Driving safety systemsSafety

It may be best to deactivate ESP
®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel G
WARNING
Activate ESP ®
as soon as the situations
describe dabove no longer apply. ESP ®
will
otherwis enot be abletos tabilise the vehicle
if the vehicle starts to skid or awhee lstarts
to spin.
When you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in acutting action, which
provide sbetter grip.
R traction control is still activated.
R ESP ®
still provide ssupport when you
brake.
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ESP®
warning lamp in
the instrument cluster flashes. In such situa-
tions, ESP ®
willn ot stabilise the vehicle.
X To deactivate: (Ypage 223).
The å ESP®
OFF warning lamp in the
instrument cluster lights up. G
WARNING
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ouslyw hen the engine is running.
If the ÷ warning lamp and åwarning
lamp are lit continuously, ESP ®
is not availa-
ble due to amalfunction.
There is an increased risk of yourv ehicle skid-
ding in certain situations.
You should alway sadapt your driving style to

ESP ®
trailer stabilisation If your vehicle with trailer (vehicle/trailer
combination) begins to lurch, you can only
stabilise the vehicle/trailer combination by
depressing the brake firmly.
In this situation ,ESP ®
assists you and can
detec tifthe vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has stabi-
lised.
Trailer stabilisation is active above speeds of
about 65 km/h. G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent
the trailer from swerving and will thus be
unable to reduce the risk of an accident. Trail-
ers with ahigh centre of gravity can tip over
before ESP ®
can detect this.
Trailer stabilisation does not work if ESP ®
is
deactivated or disabled because of amal-
function. EBD (electronic brake force distribu-
tion)
i Observe the "Important safety notes" sec-
tion (Y page 61).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
WARNING
If EBD has malfunctioned, the braking system
remains available with full brake boosting
effect.H owever, the rear wheels can still lock,
e.g. under full braking. This could cause you
to lose control of your vehicle and cause an
accident .You should therefor eadapt your Driving safety systems

Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessary warnings or the unnecessary
intervention of PRE-SAFE ®
Brake. To end this,
you can either depress the accelerator pedal
further, activate kickdown or release the
brake pedal.
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you drive slower than approximately
15 km/h.
R you manoeuvre to avoid the obstacle.
R there is no longer any danger of arear-end
collision.
R there is no longer an obstacle detected in
front of your vehicle.
With the help of the radar sensor system,
PRE-SAFE ®
Brake can detect obstacles that
are in front of your vehicle for an extended
period of time.
At speeds up to approximately 70 km/h,
PRE-SAFE ®
Brake may also detect stationary
obstacles, for example stopped or parked
vehicles.
If you approach an obstacle and PRE-SAFE ®
Brake detect sarisk of acollision, the system
will initially alert you both visually and acous-
tically. If you do not brake or take evasive
action, the system will warn you by automat-
