2011 MERCEDES-BENZ E-CLASS COUPE warning lights

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

Problems with child seat recognition
Problem Possible causes/consequences and
M Solutions
The
4 PASSENGER
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.

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

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 ®

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.

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.

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)

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-
ically braking the vehicle gently. If there is an

Important safety notes
Xenon bulbs If your vehicle is equipped with xenon bulbs,
you can recognise this by the following: the
cone of light from the xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before startingt he engine. G
DANGER
Xenon bulbs carry ahigh voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric con- tacts on xenon bulbs. Therefore, never
remove the cover from xenon bulbs.
Do not change xenon bulbs yourself, but have
them replaced at
aqualified specialist work-
shop which has the necessary specialist
knowledge and tools to carry out the work
required.
Mercedes-Ben zrecommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs There are bulbs other than the xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y
page 122). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centr efor this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
If you require assistanc echangin gbulbs, con-
sult aqualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the servic elife of the bulbs. Always use alint-
free cloth or only touch the base of the bulb
when fitting.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult
aq ualified specialist workshop.
