Indicator and warning
lamps
Technology that monitors itself
The indicator and warning lamps identified
by the
+ symbol are subjected to an oper-
ation check each time you switch on the
ignition or start the engine. They each light
up once for different periods of time.
When a malfunction occurs in a monitored
system, the corresponding lamp will either
fail to go out when the engine is started, or
it will come on again during normal driving,
usually accompanied by a Check Control
message. You will find more details on the
specified pages.
Fixed indicator and warning lampsColors The indicator and warning lamps can light
up in different colors and combinations.
>Red:
Stop immediately
or
important reminder
>Red and yellow:
Continue to drive; drive cautiously
>Yellow:
Have the system checked at the earliest
opportunity
or
for your information
>Green or blue:
For your information.
Variable indicator and warning lamps
On the display 5 of the instrument cluster,
other indicator and warning lamps appear
as necessary. Pay attention to the instruc-
tions of the accompanying Check Control
messages, also refer to page 66. Turn signals60

Opening and closing
32 If special circumstances should make it
absolutely necessary to operate the vehicle
with the lid open:
1.Coupe: close both windows as well as
the glass roof
Convertible: with closed top, close all
windows
2.Adjust the automatic climate control to
supply a high air volume, refer to
page 89.
Luggage compartment
There are four lashing eyes on the inner
corners of the luggage compartment for
securing luggage nets or securing straps to
fix luggage in position.
Also refer to Cargo loading, page 104.
Convertible: increasing luggage
compartment capacity
With the convertible top closed, you can
enlarge the luggage compartment capac-
ity:
To do so, unfold the handle and press it
downwards in the direction of travel, refer
to arrow. This folds the convertible top
compartment floor upwards.
Before opening the convertible top, run this
procedure in reverse order.
The convertible top cannot be
opened if the convertible top com-
partment floor is folded up.<
Alarm system
The concept
The vehicle alarm system responds:
>When a door, the hood, or the luggage
compartment lid is opened
>To movement in the vehicle interior:
interior motion sensor
>To changing of the vehicle's tilt if some-
one attempts to steal the wheels or tow
the vehicle
>To interruption of battery voltage.
The system responds to unauthorized vehi-
cle entry and attempted theft by simulta-
neously activating:
>An acoustic alarm, which lasts for a
period of approx. 30 seconds
>The hazard warning flashers for approx.
5 minutes
>The high beams, which flash on and off
in the same rhythm.
Arming and disarming alarm system
When you lock or unlock the vehicle, either
with the remote control or at the door lock,
the alarm system is armed or disarmed at
the same time.
The system indicates that it has been cor-
rectly armed by switching on the hazard
warning flashers for a single cycle and by
emitting an acoustic signal.
You can also open the luggage compart-
ment lid with the system armed using but-
ton on the remote control, refer to
page 28. When you close the lid, it is
secured again.
Switching off alarm
>Unlock the vehicle using the remote
control, refer to page 27
>or turn the ignition key to position 1.
