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/

i For safety reasons, the driver’s seat will
not return to its last set position if the
system recognizes the last set position as
an extreme forward position. Instead, the
driver’s seat will remain at or move to a
factory-set maximum forward position. To
again fully return the driver’s seat to your
last set position or to memory position,
adjust the seat to the desired position or
press and hold the respective memory
position button ( Y page 297).
i The last set driver’s seat and steering
wheel positions are stored when the
ignition is switched off and the position is
stored in memory.
i If the current position for the steering
wheel is in the uppermost tilt position, the
steering wheel will not move.
If the current seat position is within a
factory-set position range and the system
recognizes the current seat position to be
rearward enough for easy entry and exit,
the driver’s seat will not move to the rear.
The adjustment procedure is interrupted
briefly when the engine is started.GWarning!
Let the system complete the adjustment
procedure before setting the vehicle in
motion. All driver’s seat and steering wheel
adjustments must be completed before
setting the vehicle in motion. Driving off with
the driver’s seat/steering wheel still
adjusting could cause the driver to lose
control of the vehicle.
Crash-responsive exit aid
When you open the driver’s door after an
accident has occurred, the steering column
moves up. The position of the SmartKey in the
starter switch is insignificant. This function
facilitates exiting as well as rescue of vehicle
occupants.
The crash-responsive exit aid can only be
triggered when the easy-entry/exit feature is
activated via the control system.
Rear seat head restraints
GWarning!
For safety reasons, always drive with the rear
head restraints in the upright position when
the rear seats are occupied.
Keep the area around head restraints clear of
articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.
GWarning!
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way that it
is as close to the head as possible and the
center of the head restraint supports the back
of the head at eye level. This will reduce the
potential for injury to the head and neck in the
event of an accident or similar situation.
With a rear seat occupied, make sure to move
the respective head restraint up from the
lowest non-use position and have the
occupant adjust the head restraint properly.
Do not drive the vehicle without the seat head
restraints installed when the rear seats are
occupied. Head restraints are intended to
help reduce injuries during an accident.

GWarning!
When the DISTRONIC PLUS is braking, the
brake pedal is retracted (i.e. depressed
automatically). The pedals’ range of motion
must not be impeded by any obstacles:
R Do not place any objects in the footwell.
R Make sure that the floormats and carpets
are securely in place.
R Do not rest your foot underneath the brake
pedal, as it could otherwise be trapped.
You could otherwise cause an accident and
injure yourself and/or others.
GWarning!
The DISTRONIC PLUS is a convenience
system. Its speed adjustment reduction
capability is intended to make cruise control
more effective and usable when traffic speeds
vary. It is not however, intended to, nor does
it, replace the need for extreme care.
The responsibility for the vehicle’s speed,
distance to the preceding vehicle and, most
importantly, brake operation to ensure a safe
stopping distance, always remains with the
driver.
The DISTRONIC PLUS cannot take street and
traffic conditions into account.
Complex driving situations are not always
fully recognized by the DISTRONIC PLUS. This
could result in wrong or missing distance
warnings.
GWarning!
The DISTRONIC PLUS adaptive cruise control
is not a substitute for active driving
involvement. It does not react to pedestrians
or on stationary objects, nor does it recognize
or predict the curvature and lane layout or the
movement of preceding vehicles. The
DISTRONIC PLUS can only apply a maximum
of 40% of the vehicle’s braking power.
The DISTRONIC PLUS may not detect narrow
vehicles possibly driving in front of you, such
as motorcycles and vehicles driving in an
offset formation.
It is the driver’s responsibility at all times to
be attentive to the road, weather and traffic
conditions. Additionally, the driver must
provide the steering, braking and other driving
inputs necessary to remain in control of the
vehicle.
High-frequency sources such as toll stations,
speed measuring systems etc. can cause the
DISTRONIC PLUS system to temporarily
cease functioning.GWarning!
The DISTRONIC PLUS cannot take road and
traffic conditions into account. Only use the
DISTRONIC PLUS if the road, weather and
traffic conditions make it advisable to travel
at a constant speed.
GWarning!
Use of the DISTRONIC PLUS can be
dangerous on slippery roads. Rapid changes
in tire traction can result in wheel spin and
loss of control.
The DISTRONIC PLUS does not function in
adverse sight and distance conditions. Do not
use the DISTRONIC PLUS during conditions of
fog, heavy rain, snow or sleet.
GWarning!
The DISTRONIC PLUS cannot take weather
conditions into account. Switch off the
DISTRONIC PLUS or do not switch it on if:
R roads are slippery or covered with snow or
ice. The wheels could lose traction while
braking or accelerating, and the vehicle
could skid.
R the DISTRONIC PLUS system sensor covers
are dirty or visibility is diminished due to
snow, rain or fog, for example. The distance
control system functionality could be
impaired.
Always pay attention to surrounding traffic
conditions even while the DISTRONIC PLUS is
