Roll bar (Cabriolet)
G
DANGER
If the roll bar is malfunctioning, the A
Malfunction Service Required message
appears in the multifunction display. The roll
bars
will then possibly not be extended in the
event of an accident. This could result in
severe or even fatal injuries to you and other
occupants. In this case, visit a qualified
specialist workshop immediately and have
the roll bar checked. G
WARNING
Ensure that the area around the roll bars/rear
head restraints is kept clear. Otherwise,
someone could be injured by the roll bars
when they are triggered.
The roll bars are under the rear head
restraints. They are extended if systems
detect that the vehicle is in danger of
overturning.
When the roll bars are extended, the rear
head restraints also extend automatically.
Once the roll bars are extended, you can no
longer
lower the rear head restraints. The soft
top can no longer be closed. In this case, visit
the nearest qualified specialist workshop. NECK-PRO head restraints
Important safety notes G
WARNING
Do not secure any objects (e.g. coat hangers)
on
the NECK-PRO head restraints. Otherwise,
the NECK-PRO head restraints may not
function properly, or in the event of a rear-end
collision may not be able offer the level of
protection they are designed to provide. G
WARNING
Seat or head restraint covers can cause a
malfunction when the NECK-PRO head
restraints are activated or when the side
impact air bags or pelvis air bags are deployed, or they can prevent this completely.
The
NECK-PRO head restraints or side impact
air bags/pelvis air bags can therefore not
provide the intended protection. Do not use
any seat or head restraint covers. G
WARNING
For your protection, drive only with properly
positioned head restraints.
Adjust
the head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation. G
WARNING
For safety reasons, have the NECK-PRO head
restraints checked at a qualified specialist
workshop after a rear-end collision.
The NECK-PRO head restraints reduce the
likelihood of head and chest injuries. The
NECK-PRO
head restraints on the driver's and
front-passenger seats are moved forwards
and upwards in the event of a rear-end
collision of a certain severity. This provides
better head support.
If the NECK-PRO head restraints have been
triggered in an accident, reset the NECK-PRO
head restraints on the driver’s and front-
passenger seat ( Y page 51). Otherwise, the
additional protection will not be available in
the event of another rear-end collision. You
can recognize when NECK-PRO head
restraints have been triggered by the fact that
they have moved forwards and can no longer
be adjusted.

Brake (Y page 67) Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good
time. 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.
i The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Please pay special
attention to the notes on tires,
recommended minimum tire tread depths,
etc. (Y page 322).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible. ABS (Anti-lock Braking System)
Important safety notes i
Observe the "Important safety notes"
section ( Y page 64).G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are
deactivated. There is an increased danger
of skidding and accidents. Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become
inoperative. Observe the information
on the ABS warning lamp ( Y page 258) and
display messages which may be shown in the
instrument cluster (Y page 229).
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.
ABS works from a speed of about 5 mph
(8 km/h) upwards, regardless of road-surface
conditions. ABS works on slippery surfaces,
even if you only brake gently.
The yellow ! ABS warning lamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is
running.
Braking X
If ABS intervenes:
continue to depress the
brake pedal vigorously until the braking
situation 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, and
functions as a reminder to take extra care
while driving. BAS (Brake Assist System)
i Observe the "Important safety notes"

Observe the "Important safety notes"
section ( Y page 64).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 without 4MATIC: when towing your
vehicle with the rear axle raised, it is
important that you observe the notes on
ESP
®
(Y page 316).
ESP ®
is deactivated if the å warning lamp
in the instrument cluster lights up
continuously when the engine is running.
If the ÷ warning lamp and the å
warning lamp are lit continuously, ESP ®
is not
available due to a malfunction.
Observe the information on warning lamps
(Y page 259) and display messages which
may be shown in the instrument cluster
(Y page 229).
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.
If ESP ®
intervenes, the ÷ ESP®
warning
lamp flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any
circumstances.
X Only depress the accelerator pedal as far
as necessary when pulling away.
X Adapt your driving style to suit the
prevailing road and weather conditions.
i Only use wheels with the recommended
tire sizes. Only then will ESP ®
function
properly.
ETS/4ETS (Electronic Traction System) Traction control is part of ESP

Deactivating/activating ESP ®G
WARNING
If you deactivate ESP ®
, ESP ®
no longer
stabilizes the vehicle. There is an increased
risk of skidding and an accident.
Only deactivate ESP ®
in the situations
described in the following.
! Avoid spinning the driven wheels for an
extended period with ESP ®
deactivated.
You
could otherwise damage the drivetrain.

ESP ®
is activated automatically when the
engine is started.
The ECO start/stop function switches the
engine off automatically if the vehicle stops
moving.
The engine starts automatically 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.
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ ESP®
warning lamp in
the instrument cluster flashes. In such
situations, ESP ®
will not stabilize the vehicle.
It may be best to deactivate ESP ®
in the
following situations:
R when using snow chains
R in deep snow
R on sand or gravel If you deactivate ESP

R engine torque is not limited and the drive
wheels are able to spin. The spinning
wheels produce a cutting effect for better
traction. EBD (electronic brake force
distribution)
i Observe the "Important safety notes"
section ( Y page 64). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases
the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps ( Y page 258) as well as
display messages ( Y page 230).
EBD monitors and controls the brake
pressure on the rear wheels to improve
