Before lowering the convertible
top, refer to page 41 or 46, always
check to ensure that the luggage com-
partment panel is folded down. Other-
wise damage could occur.<
Alarm system*The conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>To movements inside the vehicle –
interior motion sensor
>To variations in the vehicle's tilt angle
such as those occurring during
attempts to steal the wheels or tow
the vehicle – tilt alarm sensor
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>The acoustic alarm sounds for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
rhythm with the hazard warning flash-
ers.To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
via the driver's door lock or with the
remote control, the alarm system is also
simultaneously armed or disarmed.You can have different acknowl-
edgment signals set to confirm
arming and disarming.<
You can open the luggage compart-
ment lid when the system is armed by
pressing the remote control button,
refer to page 32. The lid is once again
secured when it is closed.
Extended pressure on the button sets
off the alarm – Panic mode, refer to
page 32.

Opening and closing1To close
2To open
To avoid placing unnecessary
loads on the battery, you should
avoid operating the top when the
engine is switched off.
Before closing the top, always ensure
that the windshield frame is clear of any
obstructions that could prevent the top
from closing correctly.<
With the ignition key in position 1 or
higher, and with the vehicle stationary
1. Read and comply with the preceding
safety precautions
2. Ensure that the convertible top com-
partment panel in the luggage com-
partment is folded down, see
page 37; otherwise, it will not be
possible to open the convertible top
3. Ensure that the luggage compart-
ment lid is closed
4. Maintain pressure on the corre-
sponding button for the convertible
top operation.
The luggage compartment lid can-
not be opened while the convert-
ible top is in motion.<
While the convertible top is in
motion, the rear window will move
toward the passenger compartment. To
avoid possible pinching, the area
around the closing convertible top
should be clear.<
After having been stored for an
extended period of time in the
convertible top compartment, e.g. dur-
ing the winter months because the
hardtop was being used, you may have
to support the convertible top by hand
when closing it for the first time.
If the convertible top should halt just
before the closing phase is completed,
press against the front section of the
convertible top frame from the outside
to help the closing process along. Con-
tinue pressing the switch while doing
so until the top starts up again on its
own.<
Indicator lamps>The red indicator lamp is lit whenever
the convertible top mechanism is in
motion. It goes out as soon as the
opening or closing operation has
been completed
>If the red indicator lamp flashes after
the control button is released, the
convertible top has not yet been
opened or closed completely. You
can resume operation in the desired
direction by pressing the button
again
>If the yellow indicator lamp lights up
continuously with the button pressed,

Rollover protection systemIn the event of an accident or some
other critical driving situation – extreme
tilting in the longitudinal or transverse
axis, loss of contact with the ground –
the rollover protection system will be
automatically activated. The protective
bars located in the rear head restraints
extend within fractions of a second.
In addition to the integrated rollover bar
in the windshield frame, the rollover
protection system affords all the vehicle
occupants necessary headroom.
Always keep the travel path for the
rollover protection system free
and clear. Under no circumstances
should you cover the head restraints.
In the event of less serious accidents,
the safety belt will protect you and,
depending on the severity of the acci-
dent, so will the safety belt tensioner
and the multi-stage airbag restraint sys-
tem as well.<
If, after being automatically triggered,
its protective function is not needed,
then the rollover protection system can
be lowered back into place. No special
tool is needed for this.
1. Using a screwdriver from the
onboard tool kit, remove the cover
panel; to do this, position the screw-
driver under the notch
2. Push the lever toward the front of the
vehicle and keep it in this position

sequential mode is activated as soon as
you move the selector lever into the for-
ward driving position while the brake is
depressed.
The gears are shifted via the shift pad-
dles or the selector lever.
It is also possible to drive off in second
gear, e.g. on snow-covered roads.DDrive modeIn the drive mode all forward gears are
shifted automatically.
To switch from sequential to drive
mode: tap the selector lever to the right
toward D.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely: kickdown.To switch back to sequential mode: tap
the selector lever again to the right
toward D or change the current gear via
the shift paddles or the selector lever.
KickdownYou can achieve maximum acceleration
using kickdown.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
Shifting gearsWith the selector lever:
>To upshift, tap the selector lever
toward +
>To downshift, tap the lever toward —.
With the shift paddles on the steering
wheel:
>To upshift, pull one of the shift pad-
dles
>To downshift, push the paddle.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations, the SMG in
the sequential mode assists you:
>Upshifts and downshifts are only exe-
cuted at appopriate combinations of
engine rpm and vehicle speed. For

instance, downshifts that would
result in excessive engine speed can-
not be executed.
>When you brake the car to a stop, the
transmission automatically shifts
down to first gear
>As speed diminishes the transmission
will shift down automatically, without
any action on your part, just before
the vehicle slows to below each
gear's minimum speed.

Automatic transmission with Steptronic*You can drive as with a normal auto-
matic transmission. In addition, you can
also shift manually.
When you move the selector lever from
the D position to the left into the M/S
range, the performance-oriented shift
programs of the automatic transmission
are engaged. Steptronic enters the
manual selection mode and executes
the desired shift whenever you tap the
selector lever in the direction indicated
by + or –. Whenever you want to use
automatic again, just move the selector
lever toward the right to position D.
Under normal operating conditions, fuel
consumption is lowest when driving in
position D.Selector lever positionsP R N D M/S + –Starting the engineThe engine can only be started in selec-
tor lever positions P – for Park – or N –
for Neutral.
Range selectionA catch prevents inadvertent movement
of the selector lever to positions R and
P. To deactivate the catch, press the
button on the front of the selector lever
knob, see arrow.
While the vehicle is stationary and
before shifting out of Park or Neu-
tral, depress the footbrake in order to
disengage the selector lever's lock
mechanism – Shiftlock.<
Hold the footbrake down until
starting off. Otherwise the vehicle
will 'creep' when a drive position is
engaged. To prevent the vehicle from
starting off on its own, always move the
selector lever to position P and engage
the parking brake before leaving your
vehicle with the engine running.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a safety hazard.<

KickdownIn the kickdown mode, you achieve
maximum acceleration and top speed
in position D.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
M/S manual operation and Sport
programMove the selector lever from D to M/S
to activate the Sport program; SD
appears in the display panel. The M/S
mode is recommended for perfor-
mance-oriented driving.
Once in the M/S mode, you can tap the
selector lever to switch the automatic
transmission from the Sport program to
its manual selection mode.
This mode allows you to execute
upshifts manually by tapping the lever
toward +, while downshifts are selected
by tapping in the – direction. The dis-
plays M1 through M5 appear in the dis-
play panel to indicate your current gear
selection.
The transmission will only execute
upshifts and downshifts that will result
in an appropriate combination of vehi-
cle speed and engine rpm. For
instance, downshifts that would result
in excessive engine speed are not exe-
cuted. The desired, then the actual
gear, briefly appear in the instrument
cluster.
To accelerate quickly in the man-
ual mode for maneuvers such as
passing another vehicle, shift down
manually or employ the kickdown
mode.<
Shifting from M/S to the selector lever
positions P, R and N is possible only by
going through D.
