Voice command system
The concept
The voice command system allows you to 
control operation of various vehicle sys-
tems without ever removing your hands 
from the steering wheel.
Individual menu items on the Control Dis-
play can be spoken as commands. Opera-
tion via the controller is not required.
The voice command system transforms 
your oral commands into control signals for 
the selected systems and provides support 
in the form of instructions or questions.
The voice command system includes a 
special microphone.
The microphone is located:
>On the Coupe near the interior rearview 
mirror, refer to page 14
>On the Convertible near the interior 
rearview mirror, refer to page 14, or on 
the steering column.
Precondition
The set language of the Control Center and 
of the voice command system should 
match so that the commands to be spoken 
can be identified more easily. Setting the 
language of the Control Center, refer to 
page 73.

The central locking system can be oper-
ated from the outside
>via the remote control
>via the door lock
and from inside via the button for the cen-
tral locking system.
If operated from the inside, the fuel filler 
door and the compartment in the front 
center console are not locked, refer to 
page 29.
The anti-theft system is automatically acti-
vated whenever you activate the central 
locking system from outside the vehicle. 
It prevents the doors from being unlocked 
using the safety lock buttons or door han-
dles. The alarm system is armed/disarmed 
at the same time.
In the event of an accident, the central 
locking system unlocks automatically. The 
hazard warning flashers and interior lamps 
also switch on.

Using the remote control 
When you lock/unlock the vehicle, you 
simultaneously activate/deactivate the 
anti-theft system, arm/disarm the alarm 
system, and switch the interior lamps on/
off.
Protect the remote control against 
unauthorized use by handing over 
only the spare key, for example when using 
hotel valet parking.<
You can find more detailed information on 
the alarm system on page 32.
Because any persons or animals left 
unattended in a parked vehicle could 
lock the doors from the inside, you should 
always keep the remote control with you; 
this precaution ensures that you will remain 
able to unlock the vehicle from the outside 
at all times.<

tem and then pull the door handle 
above the armrest or
>pull the door handle for each door 
twice: the first pull unlocks the door,

lock the doors from the inside, always take 
the master key with remote control with 
you to ensure that you will remain able to 
unlock the vehicle from the outside when-
ever the need arises.<
Hotel function 
The hotel function locks the compartment 
in the front center console and the luggage 
compartment lid individually and discon-
nects them from the central locking sys-
tem. The spare key, refer to page 26, does not fit the lock for the hotel function. If you 
then only hand over the spare key, e.g. in a 
hotel, no access is possible to the luggage 
compartment lid or to the compartment in 
the front center console.
Turn the key to the right, refer to illustration, 
and remove.
The hotel function is only activated after 
subsequent locking or unlocking of the 
vehicle. This locks the luggage compart-
ment lid and the compartment in the front 
center console and disconnects them from 
the central locking system.
In the event of an electrical 
malfunction 
For manual unlocking, turn the master key 
all the way to the right:
The compartment in the front center con-
sole is unlocked.
If unlocking was manual, the lock has 
to be returned to the home position, 
i.e. all the way back to the left, before set-
ting the hotel function again.<
Luggage compartment lid 
Coupe: the luggage compartment lid 
swings to the rear and upwards when 
opened. Make sure there is sufficient free 
space.< 

Driving
56 do not pull it too strongly. In doing so, con-
tinuously press the button of the handbrake 
lever.
Strong application of the handbrake can 
lead to overbraking of the rear axle and 
associated 'fishtailing' of the vehicle rear 
end.
The brake lamps do not light up when the 
handbrake is engaged.
Vehicles with manual or SMG transmission: 
When parking on inclines, engage the 
handbrake, as even engaging the first or 
reverse gear might not under certain cir-
cumstances secure the vehicle against 
moving.
Vehicles with automatic transmission:
Engage selector-lever position P.<
To prevent corrosion and one-sided 
braking action, occasionally engage 
the handbrake lightly when the vehicle is 
slowly coming to a standstill if the traffic 
conditions are suitable.<
Manual transmission 
While shifting gear in the 5th/6th  gear 
level, press the gearshift lever to the 
right, as otherwise engine damage could 
occur from inadvertently engaging a gear in 
the 3rd/4th gear level.
On inclines, do not hold the vehicle with the 
clutch; use the handbrake. Otherwise there 
is high clutch wear.<
Reverse gear 
Select only when the vehicle is completely 
stationary. When pressing the gearshift 
lever to the left, overcome some resis-
tance.The backup lamps automatically switch on 
in ignition key position 2.
SMG Sequential manual 
transmission* 
The concept
The SMG Sequential manual transmission 
is an automated manual transmission in 
which an electro-hydraulic system handles 
the clutching and gear changes.
You operate the SMG using the selector 
lever in the center console and two shift 
paddles on the steering wheel.
It offers the following functions:
>Choice of manual or automatic mode: 
Sequential mode or Drive mode
>Options of two drive programs: 
Normal or Sport, refer to page 59
>Protection against incorrect gearshifts 
and automatic shift down at minimum 
engine speed, also in the Sequential 
mode
>Kickdown function in the Drive mode
>Acceleration assistant, refer to 
page 60.
The SMG is operational in ignition key posi-
tion 2.
Selector-lever positions 
The current selector-lever position is dis-
played on the center console.
>R: Reverse gear
>N: Neutral, idle
