Indicator and warning lamps
The concept
Indicator and warning lamps can light up in a 
variety of combinations and colors.
Some lamps are checked for proper functioning 
and thus come on briefly when the engine is 
started or the ignition is switched on.
Explanatory text messages
Text messages at the lower edge of the Control 
Display explain the meaning of the displayed 
indicator and warning lamps.
You can call up more information, e.g. on the 
cause of a malfunction and on how to respond, 
via Check Control, refer to page83.
In urgent cases, this information will be shown 
as soon as the corresponding lamp comes on.

Central locking system
The concept
The central locking system is ready for opera-
tion whenever the driver's door is closed.
The system simultaneously engages and 
releases the locks on the following:
>Doors
>Luggage compartment lid
>Fuel filler door
> Convertible: center armrest and glove com-
partment
Operating from outside
>Via the remote control
>Via the door lock
>In cars with convenient access
*, via the 
handles on the driver's and front passen-
ger's doors
The anti-theft system is also operated at the 
same time. It prevents the doors from being 
unlocked using the lock buttons or door han-
dles. In addition, if the remote control is used, 
the welcome lamps, interior lamps and the 
door's courtesy lamps
* are switched on or off. 
The alarm system
* is also armed or disarmed.
For further details of the alarm system,
 refer to 
page35.
Operating from inside
By means of the button for central locking, refer 
to page32.
In the event of a sufficiently severe accident, the 
central locking system unlocks automatically. In 
addition, the hazard warning flashers and inte-
rior lamps come on.
Opening and closing:
Using the remote control
Persons or animals in a parked vehicle 
could lock the doors from the inside. You 
should therefore take the remote control with 
you when you leave the vehicle so that the latter 
can be opened from outside.<
Convertible: to operate the retractable 
hardtop with the remote control, the 
doors and luggage compartment lid must be 
closed and the cargo bay partition must be 
folded down and engaged on both sides. Refer 
also to page41.<
Unlocking
Press the   button.
The interior lamps, the courtesy lamps
* and the 
welcome lamps come on.

senger's door completely, arrow 1. This corre-
sponds to pressing the  button.
Locking
Touch the surface, arrow 2, with your finger for 
approx. 1 second. This corresponds to pressing 
the button.
To preserve the battery, please make 
sure that the ignition and all electrical 
consumers are switched off before locking the 
vehicle.<
Coupe: convenient closure
For convenient closure, keep your finger on the 
surface, arrow 2.
Unlocking the luggage compartment 
lid separately
Press the button on the outside of the luggage 
compartment lid. This corresponds to pressing 
the button.
If the vehicle detects that a remote con-
trol has been accidentally left inside the 
locked vehicle's cargo bay after the luggage 
compartment lid is closed, the lid will reopen. 
The hazard warning flashers flash and an 
acoustic signal
* sounds.<
Switching on radio readiness
Radio readiness is switched on by pressing the 
start/stop button, refer to page59.Do not depress the brake or the clutch, 
otherwise the engine will start.<
Starting the engine
You can start the engine or switch on the igni-
tion when a remote control is inside the vehicle. 
It is not necessary to insert a remote control into 
the ignition switch, refer to page59.
Switching off the engine in cars with 
automatic transmission
The engine can only be switched off when the 
selector lever is in position P, refer to page60.
T o  s w i t c h  t h e  e n g i n e  o f f  w h e n  t h e  s e l e c t o r  l e v e r  
is in position N, the remote control must be in 
the ignition switch.
Before driving a vehicle with automatic 
transmission into a car wash
1.Insert remote control into ignition switch.
2.Depress the brake.
3.Move the selector lever to position N.
4.Switch off the engine.
The vehicle can roll.
Malfunction
Convenient access may malfunction due to 
local radio waves. If this happens, open or close 
the vehicle via the buttons on the remote con-
trol or using the integrated key. To start the 
engine afterward, insert the remote control into 
the ignition switch.
Warning lamps
The warning lamp in the instrument 
cluster lights up when you attempt to 
start the engine: the engine cannot 
be started. The remote control is not inside the 
vehicle or is malfunctioning. Take the remote 
control with you inside the vehicle or have it 
checked. If necessary, insert another remote 
control into the ignition switch.
The warning lamp in the instrument 
cluster lights up while the engine is 
running: the remote control is no 
longer inside the vehicle. After the engine is

are currently not met. Calling up Check Control 
messages, refer to page84.<
Warning lamps
The indicator2 flashes in red; a 
signal sounds. 
The system indicates that you 
must brake and/or maneuver the 
vehicle yourself. Active cruise con-
trol cannot automatically restore the distance to 
the vehicle ahead. 
This indicator does not release you from your 
responsibility to adapt your desired speed and 
driving style to prevailing driving conditions.
The indicator 2 flashes in yellow. 
The prerequisites for operating 
active cruise control are not met, 
e.g. as a result of ABS or DSC 
interventions. Active cruise control 
is deactivated. You can reactivate the system, if 
desired, by tapping or pulling the lever when 
road and traffic conditions permit. It is not pos-
sible to resume a stored speed.
Radar sensor
The sensor's ability to detect vehicles ahead 
may be restricted as a result of heavy rain, dirt, 
snow or ice. If necessary, clean the radar sensor 
located in the front bumper, see arrow. Be sure 
to use particular care when removing any layers 
of snow or ice from the sensor.
When the radar sensor is not properly posi-
tioned, active cruise control cannot be activated 
at all.
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 page83. 
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.<

Check Control
The concept

and alerts you to any malfunctions in the sys-
tems monitored. Such a Check Control mes-
sage includes indicator and warning lamps in 
the instrument cluster and, in some circum-
stances, an acoustic signal as well as text mes-
sages at the bottom of the Control Display.
