The side windows will move down slightly
when you press the button for operating
the convertible top.
After the opening or closing operation, the win-
dows will move back up if you press the button
for more than 2 seconds after the LED has gone
out.<
When the convertible top has been stored
in the convertible top compartment for an
extended period of time, e.g. in 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 con-
vertible top stops right before the closing phase
is completed, press against the front part of the
convertible top frame from the outside to help
the closing process along. Keep pressing the
button while doing so until the top starts mov-
ing on its own again.<
Indicator lamps
>The red LED in the button is lit while the
convertible top is in motion. It goes out as
soon as the opening or closing operation
has been completed.
>If the red LED in the button flashes after the
button has been released, then the opening
or closing operation has not yet been com-
pleted.
The movement can be continued in the
desired direction by pressing this button.>If the yellow LED in the button comes on
when the button is pressed, the convertible
top compartment panel in the cargo bay has
been folded up. The convertible top cannot
be moved.

immediately if you release the button that oper-
ates the top. The sequence can be continued in

Special starting conditions
In the following situations, press the accelerator
pedal halfway down when starting the engine:
>If the engine does not start on the first
attempt, for instance when it is extremely
hot or cold.
>If the engine is started at very low tempera-
tures, below approx. +57/–156, at high
altitudes above approx. 3,300 ft/1,000 m.
Avoid frequent starting attempts in quick
succession or repeated starting attempts
during which the engine does not start. Other-
wise, the fuel is not burned or inadequately
burned; there is a danger of overheating and
damaging the catalytic converter.<
Switching off the engine
Do not remove the key while the vehicle is
still moving. Otherwise, the steering lock
would engage when the steering wheel is
turned.
When you leave the vehicle, always remove the
key and engage the steering lock.
Apply the parking brake when parking on steep
gradients, otherwise the vehicle could start to
roll.<
You can have an acoustic signal set as a
reminder that the key is still in the ignition
switch after the driver's door has been
opened.<
Manual transmission
1.Turn the key to position 1 or 0.
2.Engage first gear or reverse gear.

Parking brake
The parking brake is designed primarily to pre-
vent the vehicle from rolling when parked. It
operates against the rear wheels.
Indicator lamp
The indicator lamp is lit, and when you
drive off a signal sounds in addition.

Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If, in exceptional circumstances, it should
be necessary to engage the parking brake
while the vehicle is in motion, do not pull it with
excessive pressure. In doing so, continuously
press the button of the handbrake lever. Other-
wise, too violent an application of the hand-
brake can overbrake the rear axle and cause the
rear of the car to swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<
