Tensioning Device could be triggered in the
event of an accident.
i Vehicles with PRE-SAFE ®
: Emergency
Tensioning Devices that are triggered by an
electric motor can be deployed as often as
desired and do not need to be replaced.
The fronts eat belts and the outer seat belts
in the rear are equipped with Emergency
Tensioning Devices and seat belt force
limiters.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
The ETDs can only be activated when:
R the ignition is switched on
R the restraint systems are operational; see
"SRS warning lamp 001D" (Ypage 43)
R the belt tongue is engaged in the buckle on
each of the front seat belts
The ETDs on the outside seats in the rear
compartment are triggered independently of
the lock status of the seat belts.
The ETDs are triggered depending on the type
and severity of an accident:
R in the event of a head-on or rear-end
collision if the vehicle decelerates or
accelerates rapidly in a longitudinal
direction during the initial stages of the
impact.
R in the event of a side impact if the vehicle
decelerates or accelerates rapidly in a
lateral direction on the side opposite to the
impact.
R Cabriolet: in certain situations if the vehicle
rolls over and the system determines that
it can provide additional protection
If the ETDs are deployed, you will hear a bang,
and a small amount of powder may also be
released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a health hazard and does not indicate that there
is a fire in the vehicle. The dust might cause
some temporary breathing difficulty for
people with asthma or other breathing
trouble. To avoid this, you may wish to get out
of the vehicle as soon as it is safe to do so.
You can also open the window to allow fresh
air to enter the vehicle interior. The
001DSRS
warning lamp lights up.
If the seat belt is also equipped with a seat
belt force limiter and this is triggered, the
force exerted by the seat belt on the vehicle
occupan tis reduced.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which absorb part of the deceleration force.
This results in the force exerted on the
occupant being distributed over a greater
area.
Automatic comfort-fit feature The front seat belts have an automatic
comfort-fit feature. The automatic comfort-fit
feature reduces the retraction force of the
seat belts. This results in increased seat belt
comfort. Children in the vehicle

Important safety notes G
WARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible.R egardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child. 62

ESP
®
(Electronic Stability Program)
General notes i
Observe the "Important safety notes"
sectio n(Ypage 68).
ESP ®
monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize 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 stabilize the vehicle during braking.
ETS/4ETS (Electronic Traction System) ETS/4ETS traction control is part of ESP
®
.
Traction control brakes the drive wheels
individually 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. In addition, more drive torque is
transferred to the wheel or wheels with
traction.
Traction control remains active, even if you
deactivate ESP ®
.
Important safety notes i
Observe the "Important safety notes"
section (Y page 68). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
! Vehicles with 4MATIC: switch off the
ignition when the parking brake is being
tested on a brake dynamometer. Application of the brakes by ESP
®
may
otherwise destroy the brake system.
! Vehicles with 4MATIC: function or
performance tests may only be carried out
on a 2-axle dynamometer. Before you
operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage
the drive train or the brake system.
Vehicles without 4MATIC: observe the notes
on ESP ®
(Y page 337) when towing the
vehicle with a raised rear axle.
ESP ®
is deactivated if the 0015warning lamp
in the instrument cluster lights up
continuously when the engin eis running.
If the 000C warning lamp and the 0015
warning lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
(Y page 279) and displaym essages which
may be shown in the instrument cluster
(Y page 249).
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
Characteristics of ESP ® General information
If the
000C ESP warning lamp goes out before
beginning the journey, ESP ®
is automatically
active.

If ESP ®
intervenes:
X Do not deactivate ESP ®
under any
circumstances.
X Only depress the accelerator pedal as far
as necessary when pulling away.

G
WARNING
If you do not fully open/close the soft top, the
soft-top hydraulics depressurize after a short
time. This causes the soft top to lower
unexpectedly and may cause you or others to
be trapped. There is a risk of injury.
Always open or close the soft top completely.
! Never sit on the soft-top compartment
cover or stow heavy objects there. You will
otherwise damage the soft top and soft-top
compartment cover of the vehicle. !
When opening and closing the soft top,
make sure that:
R there is sufficien tclearance above it, as
the soft top swings upwards.
R the trunk partition is closed.
R the trunk is only loaded to below the
trunk partition.
R the trunk partition is not pushed up by
the load.
R the trunk lid is closed.
R there are no objects on the soft-top
compartment cover
R the fabric is not dirty, wet or frozen.

You can open or close the soft top:
R when the vehicle is stationary or
R when you do not exceed aspeed of
25 mph (40 km/h).
If there is a strong head wind, it may not be
possible to close the soft top fully. In this
case, reduce speed or stop in order to close
the soft top fully.
For safety reasons, Mercedes-Benz
recommends that you only open or close the
soft top when the vehicle is stationary.
If the soft top does not open or close fully, the
soft-top hydraulics are depressurized and the

Compensate for this by applying greater force
to the brake pedal. The first 1000 miles(1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R You should therefore drive at varying
vehicle and engine speeds for the first
