ignition key removed, as long as a door has
not been opened.For information on using the convenience oper-
ation mode at the door lock or with the remote
control, refer to page30 or31.
Anti-trapping mechanism
If the glass sunroof encounters resistance when
closing, the closing action is interrupted and the
glass sunroof opens.
If the sliding panel encounters resistance when
closing within the last approx. 8 in/20 cm, the
closing action is interrupted and the sliding
panel opens again slightly.
Despite the anti-trapping mechanism,
you should inspect the sunroof's travel
range prior to closing it, as the safety feature
might fail to detect certain kinds of obstruc-
tions, such as very thin objects, and the sunroof
would continue closing.
Pressing the switch beyond the resistance
point and holding it deactivates the anti-trap-
ping mechanism.<
Following interruptions in electrical
power supply
After an interruption in the power supply the
glass sunroof may not move. The system has to

Opening and closing
40 dren away from the travel path of the convert-
ible top.
For safety reasons, only operate the convertible
top when the vehicle is at a standstill.<
If you have initiated top operation with the
vehicle at a stop and then start to drive,
e.g. at a traffic light, you can continue the ini-
tiated operation up to a speed of 20 mph/
30 km/h:
To do so, press and hold the corresponding
button.<
Partial vacuums that occur at higher
speeds in the passenger compartment
can make the convertible top flap. Use the auto-
matic climate control to increase the air supply
so that a partial vacuum in the vehicle does not
occur.<
Prior to opening and closing
>Read carefully and comply with the safety
precautions that appear above.
>Ensure that the convertible top compart-
ment floor in the luggage compartment is
folded down, refer to page34, as otherwise
the convertible top cannot be opened.
>Ensure that the luggage compartment lid is
closed.
Opening and closing
With the ignition key in position 1 or greater,
refer to page54, and the vehicle stationary:
So as not to place an excessive load on
the battery, only operate the convertible
top with the engine running, if possible.

When the button for top operation is
pressed, the side windows move down-
ward slightly; the rear window is lowered com-
pletely.
If you hold down the button after the LED2
goes out, the windows are raised again.
If the opening or closing action is not com-
pleted, the luggage compartment lid cannot be

Display and an acoustic signal may sound:
>During convertible top operation, the LED
lights up green. It goes out as soon as the
opening or closing action is ended.
> If the LED flashes red when you release the
button, the opening or closing action has
not yet finished.
>If the LED lights up red when the button is
pressed, either the floor of the convertible
top storage compartment in the luggage
compartment is in the raised position or a
malfunction has occurred. The convertible
top cannot be moved.
Interruption
The automatic sequence of movements is
interrupted immediately if the button for top
operation is released. The sequence can be
continued in the desired direction using the
button.
If the opening or closing action is interrupted for
a longer period, the convertible top remains in
that position for approx. 15 minutes before it
slowly moves to a stable position.
A convertible top which is not completely
opened or closed presents a danger.
Do not interrupt and continue the closing action
several times in succession, as otherwise the
top mechanism can be damaged.<

Adjustments
Sitting safely
The ideal sitting position can make a vital con-
tribution to relaxed, fatigue-free driving. The sit-
ting position also plays an important role
together with the safety belts and airbags in
providing occupants with maximum levels of
passive safety in an accident. To ensure that
the safety systems operate with optimal effi-
ciency, we strongly urge you to observe the
instructions contained in the following section.
For additional information on transporting chil-
dren safely, refer to page52.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
hold the steering wheel by its rim with hands at
the 9 o'clock and 3 o'clock positions, to mini-
mize the risk of injuries to your hands and arms
in the event of airbag deployment.
No one and nothing is to come between the air-
bags and the seat occupant.
Do not use the cover of the front airbag on the
front passenger side as a storage area. Make
sure that the front passenger is sitting correctly
and does not rest feet or legs on the instrument
panel, otherwise leg injuries can occur if the
knee and front airbags are triggered.
Never let an occupant's head rest near or on a
side airbag because the inflating airbag could
cause a serious or fatal injury.<
Even if you adhere to all the instructions, inju-
ries resulting from contact with airbags cannot
be fully excluded, depending on the circum-
stances. The ignition and inflation noise may
provoke a mild hearing loss in extremely sensi-
tive individuals. This effect is usually only tem-
porary.
For airbag locations and additional information
on airbags, refer to page86.
Safety belt
Fasten your safety belt before starting any trip.
Airbags complement the safety belt as an addi-
tional safety device, but they do not represent a
substitute.
Your vehicle has four seats that are all equipped
with a safety belt.
At all times, occupants should sit upright
and be properly restrained: infants and
small children in appropriate child-restraint sys-
tems; larger children and adults using the safety
belts.
Never allow more than one person to wear a sin-
gle safety belt. Never allow infants or small chil-
dren to ride in a passenger's lap.
Expectant mothers should always wear their
safety belts, taking care to position the lap belt
against the lower hips, where it will not exert
pressure against the abdominal area.
Do not route the belt across your neck, or run it
across sharp edges. Be sure that the belt does
not become caught or jammed. Avoid twisting
the belt while routing it firmly across the hips
and shoulder. Do not allow the belt to rest
against hard or fragile objects. Otherwise, in the
event of a frontal impact, a loose lap belt could
slide over your hips, leading to abdominal injury.
Avoid wearing clothing that prevents the belt
from fitting properly and pull the shoulder belt
periodically to readjust the tension across your
lap in order to avoid a reduction in the retention
effect of the safety belt.<
For instructions on operating safety belts, refer
to page48.
Seats
Note before adjusting
Never attempt to adjust your seat while
operating the vehicle. The seat could
respond with unexpected movement, and the
ensuing loss of vehicle control could lead to an
accident.

Starting engine
Do not run the engine in closed rooms, as
otherwise the inhaling of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the engine running, as such a vehicle represents a
potential safety hazard.
To prevent the vehicle from rolling, always
select neutral position or position N and apply
the handbrake before leaving the vehicle with
the engine running.<
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive immediately at a moder-
ate engine speed.

starting if
>the engine fails to start on the first attempt,
for instance, if it is very hot or cold
>the engine is started at very low tempera-
tures, below approx. + 57/– 156, at high
altitudes, above 3,300 ft/1,000 m
Avoid frequent starting in quick succes-
sion or repeated start attempts in which
the engine does not start. Otherwise, the fuel is
not burned or inadequately burned and there is
a danger of overheating and damaging the cat-
alytic converter.<
