Arming and disarming
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.
You can open the luggage compartment lid
even when the alarm system is armed, by
pressing the button on the remote control,
refer to page28. The lid is locked and moni-
tored again as soon as you close it.
Panic mode*
You can trigger the alarm system if you find
yourself in a dangerous situation:
Press the button for at least three seconds.
To switch off the alarm: press any button.
Switching off an alarm
>Unlock the car with the remote control, refer
to page27.
>Insert the remote control all the way into the
ignition lock.
Indicator lamp displays
>The indicator lamp under the inside rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking:
doors, hood or luggage compartment lid are
not properly closed. Even if you do not close
the alerted area, the system begins to mon-
itor the remaining areas, and the indicator
lamp flashes continuously after approx.
10 seconds. The interior m o t i o n s e n s o r a n d
the tilt alarm sensor are not activated.>The indicator lamp goes out after unlocking:
your vehicle has not been disturbed while
you were away.
>If the indicator lamp flashes after unlocking
until the remote control is inserted in the
ignition, but for no longer than approx.
5 minutes: your vehicle has been disturbed
while you were away.
Tilt alarm sensor
The tilt of the vehicle is monitored. The alarm
system reacts, e.g. to attempts to steal a wheel
or tow the vehicle.
Interior motion sensor
Coupe
In order for the interior motion sensor to func-
tion properly, the windows and glass roof must
be completely closed
*.
Convertible
The interior of the car is monitored up to the
height of the seat cushions. Thus the alarm sys-
tem is activated together with the interior
motion sensor even if the hardtop is open. The
alarm can be triggered unintentionally by falling
objects such as leaves, refer to Avoiding unin-
tentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following
situations:
>In duplex garages
>During transport on car-carrying trains,
boats/ships or on a trailer
>When animals are to remain in the vehicle
Switching off tilt alarm sensor and
interior motion sensor
Press the button on the remote control
again as soon as the vehicle is locked.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
Driving
64 personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; heavy traffic such as during rush
hour; on curvy, winding roads, slippery roads or
roads with sharp curves such as highway off-
ramps; during inclement weather such as snow,
strong rain or fog; or when entering inter-
changes, service/parking areas or toll booths.
It is also important to regulate your vehicle's
speed and distance setting within applicable
legal limits. Always be ready to take action or
apply the brakes if necessary, especially when
the system is actively following a vehicle in front
of you. Otherwise driving situations could result
that pose the risk of accidents.<

Storing current speed
Briefly press the lever, arrow 1, or briefly pull it,
arrow 2, at a driving speed of more than approx.
20 mph or 30 km/h.The car's current speed is stored. It is displayed
on the speedometer and briefly in the instru-
ment cluster.
Increasing desired speed
Press or tap the lever to the resistance point or
beyond, arrow1, until the desired speed is dis-
played.
>Each time the lever is tapped to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
>Each time the lever is tapped beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h until
the maximum speed of 110 mph or
180 km/h is achieved.
The speed then displayed is stored and
achieved on a clear road.
Decreasing desired speed
Pull the lever, arrow 2, until the desired speed is
displayed.
The other functions work analogously to those
described under Increasing desired speed.

Malfunction
The warning lamp comes on when
the system has failed. A message appears on the Control Display. You can find
more information starting on page77.
System limitations
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, as for example, at a traffic light or a
parked vehicle. Also, the system does not react
to oncoming traffic, pedestrians or other types
of potential traffic such as a rider on horseback.
It is also possible that the system may not
detect smaller moving objects such as motor-
cycles or bicycles. Be especially alert when
encountering any of these situations as the sys-
tem will neither automatically brake, nor provide
a warning to you. Also, be aware that every
decrease in the distance setting allows your
vehicle to come closer to a vehicle in front of
you and requires a heightened amount of alert-
ness.<
Active cruise control is not and must not
be used as a collision avoidance/warning
system.<
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds
up or the lane ahead becomes clear, then your
vehicle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
While active cruise control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, e.g.
when you reduce your desired speed sharply.
The system cannot stop your vehicle. It uses
only a portion of braking system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: when you approach a vehicle
traveling at a much lower speed than your own
speed such as approaching a toll booth or when
a much slower vehicle cuts in front of you at
close range.<
Active cruise control can only decelerate the
vehicle to approx. 20 mph or 30 km/h.

Check Control
The concept
The Check Control monitors vehicle functions
and alerts you to any malfunctions in the sys-
tems monitored. A Check Control message
involves the indicator and warning lamps in the
instrument cluster, an acoustic signal if applica-
ble, and text messages on the Control Display.
Indicator and warning lamps
Indicator and warning lamps can light up in a
variety of combinations and colors.
