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. The system oper-
ates on the basis of voice commands that 
you will learn easily after using them a few 
times. In many cases, the voice command 
system supports you with announcements 
or questions while you are making your 
entries.
The voice command system transforms 
your oral commands and dialog answers 
into control signals for the selected sys-
tems.
Please take the time to acquaint your-
self with how a particular system 
operates before proceeding to control it 
using the voice command system.<

Voice commands
Voice command system activation
Briefly press the button on the steer-
ing wheel.
A signal tone and "SVS active" in the Info 
Display, refer to page27, indicate that the 
system is ready for use. You are automati-
cally in the main menu.
From here, you can call up all the equip-
ment that can be operated.
Canceling voice command
Briefly press the button on the steer-
ing wheel
or 
In dialogs in which any text can be spoken, 
e.g. names, notes, canceling is only possi-
ble using the button.
The system automatically switches 
over to its telephone mode if you 
receive a call during voice command. 
"SVS off" appears in the Info Display, refer 
to page27.<
Voice commands
The voice command system operates on 
the basis of specific, predefined com-
mands; these commands should be spo-
ken precisely as indicated. You can have 
the possible commands read back at any 
stage. To do so, say the command 
{Options}. 
In addition to the commands described, 
there are often other commands that run 
the same function. Instead of {Options}, 
you can, for example, also say {What now}.

More detailed commands such as 
{Change scale} instead of {Scale} are also 
often possible.
Short commands
With the {Main menu} level, you can run 
certain functions directly with brief com-
mands, refer to page29, without having to 
open an equipment level.
For example, if you want to dial a phone 
number, you do not have to say 
rather you can say directly 
Special commands 
Special commands are available for spe-
cific systems. In this Owner's Manual you will find these commands in the sections 
describing the individual systems.
Displays in Info Display
The Info Display shows you what the voice 
command system has understood in line 2, 
while also indicating which voice command 
or question is currently active in line1.
In addition, any error messages are also 
displayed.
Selecting navigation scale – an example
Start the dialog:
Briefly press in the steering wheel.
Volume adjustment 
You can adjust the volume for the instruc-
tions from the voice command system:Turn the button during an instruction/
announcement to select the desired vol-
ume.
Instructions/announcements from the 
voice command system will continue at this 
volume level, even if the other audio 
sources are set to minimum volume.
The system automatically selects your 
individual volume setting each time 
you unlock the vehicle using your personal 
remote control.<  {Telephone}

Sitting safely 
The ideal sitting position can make a vital 
contribution to relaxed driving that is as 
fatigue-free as possible. The sitting posi-
tion plays an important role together with 
the safety belts and airbags in an accident. 
To ensure that the safety systems operate 
with optimized efficiency, we strongly urge 
you to observe the instructions contained 
in the following section.
For additional information on transporting 
children safely, refer to page58. 
Sitting safely with airbags 
Always maintain an adequate dis-
tance between yourself and the air-
bags. Always hold the steering wheel by its 
rim with hands at the 9 o'clock and 
3 o'clock positions, to minimize the risk of 
injuries to your hands and arms in the event 
of airbag deployment. 
No one and nothing is to come between the 
airbags and the seat occupant. 
Do not use the cover of the front airbag on 
the front passenger side as a storage area. 
Make sure that the front passenger is cor-
rectly seated and does not rest feet or legs 
on the instrument panel, otherwise leg inju-
ries can occur if the knee and front airbag 
are triggered. 
Never let an occupant's head rest near or 
on a side airbag because the inflating air-
bag could cause a serious or fatal injury.<
Even if you adhere to all the instructions, 
injuries resulting from contact with airbags 
cannot be fully excluded, depending on the 
circumstances. The ignition and inflation 
noise may provoke a mild – usually tempo-
rary – hearing loss in extremely sensitive 
individuals.
For airbag locations and additional infor-
mation on airbags, refer to page98.
Sitting safely with safety belts 
Even though there is an airbag, wear a 
safety belt every time you get in the vehicle. 
Although airbags enhance safety by pro-
viding added protection, they are not a 
substitute for safety belts.
Your vehicle has five seats that are all 
equipped with a safety belt.
At all times, occupants should sit 
upright and be properly restrained, 
infants and small children in appropriate 
child-restraint systems; larger children and 
adults using the safety belts.
Expectant mothers should always wear 
their safety belts, taking care to position the 
lap belt against the lower hips, where it will 
not exert pressure against the abdominal 
area.
Never allow more than one person to wear 
a single safety belt. Never allow infants or 
small children to ride in a passenger's lap. 
Do not route the belt across your neck, or 
run it across sharp edges. Be sure that the 
belt does not become caught or jammed. 
Avoid twisting the belt while routing it firmly 
across the hips and shoulder. Do not allow 
the belt to rest against hard or fragile 
objects. Otherwise, in the event of a frontal 
impact, a loose lap belt could slide over 
your hips, leading to abdominal injury. 
Avoid wearing clothing that prevents the 
belt from fitting properly and pull the lap 
belt periodically to readjust the tension 
across your shoulder in order to avoid a 
reduction in the retention effect of the 
safety belt.<
For instructions on operating safety belts, 
refer to page51.

The operating concept is the same as for 
the front seat ventilation. 
Active seat for driver* 
Active adjustment of the seat cushion's 
contours reduces muscular tension and 
fatigue to help prevent lower back pain. 
To activate: press the button, the indicator 
lamp comes on. 
Mirrors 
Adjusting exterior mirrors 
14-way adjustment 
2Selecting mirror for adjustment To prevent the exterior mirrors on this 
vehicle from being damaged, always 
fold them in by hand before entering an 
automatic car wash.< 
You can also adjust the mirrors manually by 
pressing against the outer edges of their 
lenses. 
Storing the mirror positions, refer to Seat, 
mirror and steering wheel memory on 
page55. 
The mirror on the passenger's side 
features a lens with a more convex 
surface than the mirror installed on the 
driver's side. When estimating the distance 
between yourself and other traffic, bear in 
mind that the objects reflected in the mirror 
are closer than they appear. This means 
that estimations of the distance to following 
traffic should not be regarded as precise.< 
Self-defrosting mirrors 
The mirrors are automatically heated when-
ever the ignition is switched on. 
Interior and exterior mirrors, 
automatic dimming feature* 
These mirrors dim steplessly during for-
ward driving when struck by light. There are 
two photocells located in the interior rear-
view mirror for this purpose. One is inte-
grated within the mirror's lens, refer to 
arrow, while the other is located at an offset 
position on the rear of the mirror housing. 
For trouble-free operation, keep the photo-
cells clean and do not cover the area 
between the interior rearview mirror and 
the windshield. Do not attach any kind of 
stickers on the windshield in front of the 
mirror, either.
