Mercedes-Benz recommends that you use only
driving aids that have been approved specifi-
cally for your vehicle by Mercedes-Benz. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp on the
instrument cluster lights up when the ignition is
switched on. It goes out no later than a few sec- onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
system warning lamp:
R does not light up after the ignition is switched
on
R does not go out after a few seconds with the
engine running
R lights up again while the engine is running G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This may affect
the seat belt tensioner or airbag, for example. This poses an increased risk of injury or even
fatal injury.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp
:and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the automatic deactivation system of the front-passenger front airbag.
The indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON lights up for 60 sec-
onds, then both indicator lamps are off
(PASSENGER AIR BAG ON and OFF): the front-
passenger front airbag is able to deploy in the event of an accident.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the PASSENGER AIR BAG ON indicator lamp is off, only the PASSENGER AIR BAG OFF indicator
lamp shows the status of the front-passenger
front airbag. The PASSENGER AIR BAG OFF indi-
cator lamp may be lit continuously or be off.
Depending on the person in the front-passenger seat, the front-passenger front airbag must be
either disabled or enabled; see the following
points. You must make sure of this both before
and during a journey.
R Children in a rearward-facing child
restraint system: the PASSENGER AIR BAG
OFF indicator lamp must be lit. The front-
passenger front airbag is disabled. It is imper-
ative to observe the notes on the "Automatic front-passenger front airbag deactivation sys-
tem" (Y page 47) and on "Children in the
vehicle" (Y page 54).
R Children in a forward-facing child
restraint system: depending on the installed
child restraint system and the age and size of the child, the front-passenger front airbag is
either disabled or enabled. Therefore, it is
imperative to observe the notes on the "Auto-
matic front-passenger front airbag deactiva- 40
Occupant safetySafety

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, for vehicle speed, for braking in
good time and for staying in lane. Always adapt your driving style to suit the prevailing road and
weather conditions and maintain a safe distance from the vehicle in front. Drive carefully.
The driving safety systems described work as
effectively as possible only when there is ade-
quate contact between the tyres and the road
surface. Please pay special attention to the
notes on tyres, recommended minimum tyre
tread depths etc. (Y page 310).
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-lock Braking System)
General notes ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you 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 a speed of about 8 km/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-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac- tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems, includ-
ing driving safety systems, will also become
inoperative. Observe the information on the ABS warning lamp (Y page 250) and display mes-
sages which may be shown in the instrument
cluster (Y page 217).
Braking X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions; this serves as a
reminder to take extra care while driving. BAS (Brake Assist)
General notes BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes i
Read the "Important safety notes" section
(Y page 66). G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking. 66
Driving safety systemsSafety

ETS/4ETS (Electronic Traction System)
i
Observe the "Important safety notes" sec-
tion (Y page 66).
ETS traction control is part of ESP ®
. On vehicles
with 4MATIC, 4ETS is part of ESP ®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, e.g. if
the road surface is slippery on one side. In addi-
tion, more drive torque is transferred to the
wheel or wheels with traction.
Traction control remains active if you deactivate
ESP ®
.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
Vehicles without 4MATIC: when towing your
vehicle with the front axle raised, it is important
that you observe the notes on ESP ®
(Y page 306).
If the å ESP®
OFF warning lamp lights up
continuously, ESP ®
is deactivated.
If the ÷ ESP®
warning lamp and the å
warning lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Read the information on warning lamps
(Y page 252) and display messages that may be
shown in the instrument cluster (Y page 217).
Use only wheels with the recommended tyre
sizes. Only then will ESP ®
function properly.
Characteristics of ESP ®General information
If the ÷ ESP warning lamp goes out before
you begin the journey, ESP ®
is automatically
active. If ESP
®
intervenes, the ÷ESP®
warning lamp
flashes on the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X When pulling away, depress the accelerator
pedal only as far as is necessary.
X Adapt your driving style to suit the prevailing
road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically if the vehicle stops
moving. When pulling away again, the engine
starts automatically. ESP ®
remains in its previ-
ously selected status. Example:if ESP®
was
deactivated before the engine was switched off,
ESP ®
remains deactivated when the engine is
switched on again.
Activating/deactivating ESP ®
(except
Mercedes ‑AMG vehicles) Important safety notes
i Read the "Important safety notes" section
(Y page 66).
You can select between the following ESP ®
sta-
tuses:
R ESP ®
is activated
R ESP ®
is deactivated G
WARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilises the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations descri-
bed in the following.
The spinning of the wheels results in a cut for
better traction on loose surfaces.
It may be best to deactivate ESP ®
in the follow-
ing situations:
R when snow chains are used
R in deep snow
R on sand or gravel
i Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehicle 70
