In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary. PARKTRONIC*
G
Risk of accident
PARKTRONIC is only an aid and may not
detect all obstacles. This system does not
relieve you of the need to pay attention.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid with
ultrasound. It indicates visually and audibly
the distance between your vehicle and an
object.
PARKTRONIC is automatically activated when
you switch on the ignition and release the
handbrake.
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper. :
Example: sensors in the front bumper,
left-hand side
Range of the sensors The sensors must be free of dirt, ice and
slush; otherwise, they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them.

One or more segments light up as the vehicle
approaches an obstacle, depending on the
vehicle's distance to the obstacle.
From the:
R
sixth segment onwards, you will hear an
intermittent warning tone for approx-
imately two seconds.
R seventh segment onwards, you will hear a
warning tone for approximately two sec-
onds. You have reached the minimum dis-
tance.
Deactivating/activating PARKTRONIC :
Indicator lamp
; To deactivate/activate PARKTRONIC
If indicator lamp :lights up, PARKTRONIC is
deactivated. Parking Guidance is also deacti-
vated.
i PARKTRONIC is automatically activated
when you turn the key to position 2in the
ignition lock.
Trailer towing* PARKTRONIC is deactivated for the rear area
when you establish an electrical connection
between your vehicle and a trailer.
!
Fold in the ball coupling if the trailer tow
hitch is not required. PARKTRONIC meas-
ures the minimum detection range to an
obstacle from the bumper, not the ball cou-
pling. Parking Guidance*
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to meas-
ure the road on both sides of the vehicle. A
suitable parking space is indicated by the
parking symbol. You receive steering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 157). G
Risk of accident
Parking Guidance is merely an aid and may
recommend parking spaces that are not suit-
able for parking. For example, these might be
spaces where parking is prohibited, drive-
ways, unsuitable surfaces, etc.
Parking Guidance measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Parking Guidance does not relieve you of the
responsibility for paying attention. If you rely
solely on Parking Guidance, you could cause
an accident and injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. G
Risk of accident
Objects located above the height range of
Parking Guidance will not be detected when
the parking space is measured. These are not
taken into account when the parking proce-
dure is calculated, e.g. overhanging loads, tail
sections or loading ramps of goods vehicles.
In some circumstances, Parking Guidance
might therefore issue steering instructions
too soon. This may lead to a collision. For this
reason, you should avoid using Parking Guid-
ance in such situations. Driving systems

ATTENTION ASSIST helps you on long, monot-
onous journeys such as on motorways and
trunk roads. It is active at speeds between 80
and 180 km/h. If ATTENTION ASSIST detects tiredness or increasing lapses in concentra-
tion on the part of the driver, it suggests a
break. G
Risk of accident
ATTENTION ASSIST is only an aid and may
detect your tiredness or lapses in concentra-
tion too late or not at all. It is not a substitute
for a well rested and attentive driver.
Fatigue may cause you to recognise hazard-
ous situations too late, misjudge a situation
or react slower. For this reason, make sure
you feel rested before you begin driving and
during your journey. Always take breaks in
good time and regularly, especially during
long journeys. Otherwise, you may fail to rec-
ognise dangers in time, cause an accident and
injure yourself and others.
ATTENTION ASSIST assesses your level of
fatigue or increasing inattentiveness taking
into consideration the following criteria:
R personal driving style, e.g. steering charac-
teristics
R driving conditions, e. g. time, driving time
ATTENTION ASSIST's functionality is restric-
ted and warnings are delayed or do not
appear at all:
R if the road condition is poor, e.g. large
bumps or potholes
R there is a strong side wind
R you have adopted a very sporty driving style
with high cornering speeds or driving with
a high rate of acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently operating or making a
call using COMAND APS*
R in active driving situations, for example, if
you are changing lanes or changing the
vehicle speed Driving systems

sponding side lights up red. This warning is
always issued when a vehicle enters the blind
spot monitoring range from behind or from
the side. When you overtake a vehicle, the
warning only occurs if the difference in speed
is less than 12 km/h.
The yellow indicator lamp goes out after
reverse gear is engaged. In this event, Blind
Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. G
Risk of accident
Blind Spot Assist is not active at speeds below
30 km/h, and the indicator lamps in the exte-
rior mirrors are yellow. Vehicles in the moni-
toring range are then not indicated.
