Voice Control System introduction
Safety notes
GWarning!
Only use the Voice Control System when road
and traffic conditions permit you to do so.
Otherwise you could be involved in an
accident in which you or others could be
injured.
GWarning!
Please devote your attention first and
foremost to the traffic situation you are in.
While the system permits hands-free phone
operation, attention to traffic may be diverted
not only by physical operation of a phone, but
also by the distraction of a phone
conversation while driving. As such, for safety
reasons, we encourage the driver to stop the
vehicle in a safe place before answering or
placing a phone call.
For safety reasons, you should only select a
destination when the vehicle is stationary.
While the navigation system provides
directional assistance, the driver must remain
focused on safe driving behavior, especially
attention to traffic and street signs, and
should utilize the system’s audio cues while
driving.
The navigation system does not supply any
information on stop signs, yield signs, traffic
regulations or traffic safety rules. Their
observance always remains in the driver’s
personal responsibility. Maps do not cover all
areas nor all routes within an area.
Traffic regulations always have priority over
any route recommendations given.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
GWarning!
Navigation announcements are intended to
direct you while driving without diverting your
attention from the road and driving.
Please always use navigation announcements
instead of consulting the map display for
directions. Consulting the symbols or map
display for directions may cause you to divert
your attention from driving and increase your
risk of an accident.

GWarning!
Only drive with the doors closed. Otherwise,
one or more of the doors could open while the
vehicle is in motion, putting you and/or
others at risk.
GWarning!
Make sure the trunk is closed when the engine
is running and while driving. Among other
dangers, deadly carbon monoxide (CO) gases
may enter vehicle interior resulting in
unconsciousness and death.

Safety notes
GWarning!
In order to avoid possible loss of vehicle
control the following must be done before the
vehicle is put into motion:
R seat adjustment
R head restraint adjustment
R steering wheel adjustment
R rear view mirror adjustment
R fastening of seat belts
GWarning!
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. That could cause serious
or fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a position that is as upright as
possible and seat belts are properly
positioned on the body.
GWarning!
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:
R Adjust the seat backrest until your arms are
slightly angled when holding the steering
wheel.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as possible
with the driver still able to operate the
controls properly.
R Adjust the head restraint so that it is as
close to the head as possible. The center of
the head restraint must support the back of
the head at eye level.
R Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury.GWarning!
The power seats can be operated at any time.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. A child’s unsupervised access to a
vehicle could result in an accident and/or
serious personal injury.
GWarning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For additional
information, see “Children in the vehicle”.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
