be particularly attentive. In such situations,
brake if necessary. DISTRONIC PLUS is then
deactivated.
Cornering, going into and coming out of a
bend The ability of DISTRONIC PLUS to detect
vehicles when cornering is limited. Your
vehicle may brake unexpectedly or late.
Vehicles traveling on adifferent line DISTRONIC PLUS may not detect vehicles
traveling on a different line. The distance to
the vehicle in fron twill be too short. Other vehicles changing lanes DISTRONIC PLUS has not detected the
vehicle cutting in yet. The distance to this
vehicle will be too short.
Narrow vehicles
DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the road,
because of its narrow width
.The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles DISTRONIC PLUS does not brake for
obstacles or stationary vehicles. If, for Driving systems
175Driving and parking Z

example, the detected vehicle turns a corner
and reveals an obstacle or stationary vehicle,
DISTRONIC PLUS will not brake for these.
Crossing vehicles
DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane.
Activating DISTRONIC PLUS at traffic lights
with crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
Dynamic handling package
General notes The adjustable damping system adapts to the
current driving conditions. The adjustment
depends on whether you have selected sport
or comfort mode. Your selection remains
stored even if you remove the SmartKey from
the ignition lock. Sports tuning The firmer setting of the suspension tuning in
sports mode ensures even better contact
with the road. Select this mode if you want
more direct contact with the road when
employing a sporty driving style, e.g. on
winding country roads.

Important safety notes G
WARNING
The PARKTRONIC is a supplemental system.
It is not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always remains with the driver. G
WARNING
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R move the selector lever to position D,Ror
N on vehicles with automatic transmission
R release the electric parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18km/h). It is reactivated at lower
speeds. 178

PARKTRONIC monitors the area around your
vehicle using six sensors in the frontb umper
and four sensors in the rear bumper.

Important safety notes G
WARNING
Parking Guidance is merely an aid and may
display parking spaces that are not suitable
for parking, for example:
R no-parking areas
R parking spaces with unsuitable surfaces
(road surface)
R driveways
R entrances and exits
Parking Guidance detects and measures
potential parking spaces while driving past.
Changes to the parking space after this point
are not taken into account, for example if the
vehicle in front of or behind the parking space
changes position or objects in the parking
space are moved. Even when using Parking Guidance, you are
still responsible for driving carefully. If you
rely on Parking Guidance alone, you could
cause an accident and injure yourself and
others.
Safety always remains your responsibility and
you must continue paying careful attention to
your immediate surroundings when parking
and maneuvering.
G
WARNING
Objects located above the height range of
Parking Guidance will not be detected when
the parking space is measured. These objects
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. Under some circumstances, Parking
Guidance might therefore issue steering
instructions too soon. This may lead to a Driving systems
181Driving and parking
Z

collision. For this reason, you should avoid
using Parking Guidance in such situations.
G
WARNING
Make sure that no persons or animals are in
the maneuvering range. Otherwise, they
could be injured.
! Pay particula rattention to low objects or
objects with flat surfaces ,such as trailer
drawbars, posts, cross beams and curbs.
These types of objects canno tbe detected
by Parking Guidance and may damage the
vehicle.
! If unavoidable, you should drive over
obstacles such as curbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tires.
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
As uitable parking space is indicated by the
parking symbol. You receive steering
instructions when parking .You may also use
PARKTRONIC (Y page 178).
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Use Parking Guidance for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, i.e.
not on the pavement, for example. Parking
Guidance may not detect flat curbs
Parking tips:
R on narrow roads, drive past the parking
space as close as possible.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 179) warning messages during the
parking procedure. R
when transporting a load which protrudes
from your vehicle, you must not use Parking
Guidance.
R never use Parking Guidance with snow
chains or an emergency spare wheel
mounted.
R make sure that the tire pressures are
always correct. This has adirec teffect on
the steering instructions.
R the way you rvehicle is positioned in the
parking space after parkin gis dependent
on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. In some cases, Parking
Guidance may guide you too far or not far
enough into a parking space. In some
cases, it may also lead you across or onto
the curb. If necessary, cancel the parking
procedure with Parking Guidance.

Parking Guidance is automatically activated
whe nyou drive forwards. The system is
operational at speeds of up to approximately
22 mph (35 km/h). While in operation, the
system independently locates and measures
parking spaces on both sides of the vehicle.
When driving at speeds below 19 mph
(30km/h), you will see parking symbol 0004as
a status indicator in the instrument cluster. 182
