2012 MERCEDES-BENZ CLS COUPE instrument cluster

To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R
the seat and head restraint are adjusted
properly (Y page 96).
R the seat belt has been fastened properly
(Y page 48).
R the airbags can inflate unrestricted if
deployed (Y page 42).
R the steerin gwheel is adjusted properly
(Y page 102).
R the restraint systems have not been modi-
fied.
An airbag increases the protection of vehicle
occupant swearing aseat belt. However, air-
bags are only an additional restraint system
which complements, but does not replace,
the seat belt. All vehicle occupant smust wear
their seat belt correctly at all times, even if
the vehicle is equipped with airbags. The air-
bags are not deployed in all types of acci-
dents .For example, if the protective capacity
of correctly fastened seat belts is not
increased by deploying the airbags, the air-
bags will not deploy.
Airbag deployment only provides increased
protection if the seat belt is worn correctly.
First,t he seat belt helps to keep the vehicle
occupant in the best position in relation to the
airbag. Second, in ahead-on collision, for
example, the seat belt prevent sthe vehicle
occupant from being propelled towards the
point of impact. SRS (Supplemental Restraint System)
Introduction SRS consist
sof:
R the 6 SRS warning lamp
R airbags
R the airbag control unit with crash sensors
R belt tensioners
R belt force limiters SRS reduces the risk of occupant
scoming
into contact with the vehicle's interior in the
event of an accident .Itcan also reduce the
forces to which occupant sare subjected dur-
ing an accident.

WARNING
If SRS is malfunctioning, individuals ystems
may be triggere dunintentionally or might not
be triggere dinthe event of an accident with
ah igh rate of vehicl edeceleration.
Am alfunction has occurred if:
R the 6 SRS warning lamp does not light
up when the ignitio nisswitched on.
R the engine is running and the 6SRS
warning lamp does not go out after afew
seconds.
R the engine is running and the 6SRS
warning lamp lights up again.
In this case, have SRS checked immediately
at aq ualified specialist workshop.
SRS functionsa re checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than afew seconds
after the engine is started.
Triggering of belt tensioners, belt force
limiters and airbags During the first stage of
acollision, the airbag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage. Occupant safety

Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is areminder for all occupants
to fasten their seat belts. It may light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tonec eases when the driver and
the frontp assenger have fastened their seat
belt.
For certain countries only: regardless of
whether th edriver and th efront passenger
have fastened their seat belts, the 7seat
beltw arning lamp light supfor six seconds
after th eengineiss tarted. It then goes out if
th ed river and th efront pa ssenger have fas-
tene dtheir seat belts.

You can also cancel the rear seat belt status
indicator immediately (Y page 231).

ment seat belts is only available for certain
countries.
Belt tensioners, belt force limiters G
WARNING
If the seat belt tensioners have been trig-

Observe the "Important safety notes" sec-
tion (Y page 62). 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 with 4MATIC: switch off the igni-
tion when the parking brake is being tested
using adynamometer.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
Vehicles without 4MATIC: observe the notes
on ESP ®
if the vehicle is being towed with the
rear axle raised (Y page 322).
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP ®
is not
available due to amalfunction.
Observe the information on warning lamps
(Y page 263) and display messages which
may be shown in the instrument cluster
(Y page 232).
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. 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 slippery roads. ESP ®
can also stabilise the vehicle during braking.
If ESP ®
intervenes, the ÷ESP®
warning
lamp flashes in the instrument cluster. Driving safety systems

intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X When pulling away, only depres sthe accel-

X Adapt yourd riving style to suitt he prevail-
ing road and weather conditions.
i Only use wheels with the recommended

ETS/4ETS (Electronic Traction System) Traction control 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, for
example if the road surface is slippery on one
side. On vehicles with 4MATIC, more drive
torque is also transferred to the wheel or
wheels with traction.
Traction control remains active if you deacti-
vate ESP ®
