Tips for driving with DISTRONIC PLUS General notes
Pay particular attention in the following traffic
situations:
R Cornering, going into and coming out of a
bend
R Vehicles traveling on adifferent line R
Other vehicles changin glanes
R Narrow vehicles
R Obstructions and stationary vehicles
R Crossing vehicles
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 detec
tvehicles
traveling on adifferent line. The distance to
the vehicle in fron twill be too short. Driving systems
185Driving and parking Z
Other vehicles changing lanes
DISTRONIC PLUS has not detected the
vehicle cutting in yet. The distanc etothis
vehicle will be too short.
Narrow vehicles DISTRONIC PLUS has not yet detected the
vehicle in fron tonthe 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 example, the detected vehicle turns
acorner
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.
HOLD function
General notes The HOLD function can assist the driver in the
following situations:
R
when pulling away,e speciallyonsteep
slopes
R when maneuvering on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away. 186

General notes Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. Aparking symbol
indicates asuitable parking space. Active
steering interventio ncan assis tyou during
parking. You may also use PARKTRONIC
(Y page 193).
Important safety notes Active Parking Assist is merely an aid. It is not
ar
eplacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exitin gaparking space. Make sure that
no persons, animals or object sare in the
maneuvering range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. G
WARNING
The vehicle swings out when parking and in
doing so could cross into the opposite lane.
This could result in acollision with another
road user. There is arisk of an accident.
Pay attention to other road users when
parking. Stop the vehicle if necessary or
cancel the Active Parking Assist parking
procedure.
! If unavoidable, you should drive over
obstacles such as curbs slowly and not at
as harp angle. Otherwise, you may damage
the wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example:
R where parking or stopping is prohibited
R in front of driveways or entrances and exits
R on unsuitable surfaces 196
Driving systemsDriving and parking
Parking tips:
R
On narrow roads, drive as close to the
parking space as possible.
R Parking spaces that are littered or
overgrown might be identified or measured
incorrectly.
R Parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
R Snowfall or heavy rain may lead to aparking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 195) warning messages during the
parking procedure.
R You can intervene in the steerin gprocedure
to correc titatany time. Active Parking
Assist will then be canceled.
R When transportin gaload which protrudes
from your vehicle, you should not use
Active Parking Assist.
R Never use Active Parking Assist when snow
chains are installed.
R Make sure that the tire pressures are
alway scorrect. This has adirec tinfluence
on the parking characteristics of the
vehicle.
Use Active Parking Assist for parking spaces:
R tha tare paralleltot he direction of travel
R that are on straight roads, not bends
R that are on the same leve lasthe road ,e.g.
not on the pavement
Detectin gparking spaces Objects located above the height range of
Active Parking Assist willn ot be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated ,e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. G
WARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely. You may caus
eacollision as aresult. There is
ar isk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
For further information on the detection
range (Y page194).
Active Parking Assist does not support you

Active Parking Assist is switched on
automaticallyw hen driving 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.
Active Parking Assist will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 59 in (1.5 m) wide
R that are at least 51 in (1.3 m) longer than
your vehicle
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol as a Driving systems
197Driving and parking Z
status indicator in the instrument cluster.
When
aparking space has been detected, an
arrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the
driver's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing the 000C
button on the multifunction steering wheel.
i Take note that Active Parking Assist
cannot measure the size of parking spaces
that are at right angles to the direction of
travel. You must decide for yourself
whether the vehicle will fit in the parking
space.
