Active Parking Assist

General notes

Active Parking Assist is an electronic parking aid

with ultrasound. It measures the road on both

sides of the vehicle. A parking symbol indicates

a suitable parking space. Active steering inter-

vention and brake application can assist you

during parking and when exiting a parking

space. You may also use PARKTRONIC

(

Y

page 214).

Important safety notes

Active Parking Assist is merely an aid. It is not a

replacement for your attention to your immedi-

ate surroundings. You are always responsible

for safe maneuvering, parking and exiting a

parking space. Make sure that no persons, ani-

mals or objects are in the maneuvering range.

When PARKTRONIC is switched off, Active Park-

ing Assist is also unavailable.

G

WARNING

While parking or pulling out of a parking

space, the vehicle swings out and can drive

onto areas of the oncoming lane. This could

result in a collision with another road user.

There is a risk of an accident.
Pay attention to other road users. Stop the

vehicle if necessary or cancel the Active Park-

ing Assist parking procedure.

!

If unavoidable, you should drive over obsta-

cles such as curbs slowly and not at a sharp

angle. Otherwise, you may damage the

wheels or tires.

Active Parking Assist may possibly indicate

parking spaces which are not suitable for park-

ing, for example:

R

where parking or stopping is prohibited

R

in front of driveways or entrances and exits

R

on unsuitable surfaces

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.

and

parking

R

Snowfall or heavy rain may lead to a parking

space being measured inaccurately.

R

Pay attention to the PARKTRONIC

(

Y

page 215) warning messages during the

parking procedure.

R

You can intervene in the steering procedure

to correct it at any time. Active Parking Assist

will then be canceled.

R

When transporting a load 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 always

correct. This has a direct influence on the

parking characteristics of the vehicle.

Use Active Parking Assist for parking spaces:

R

parallel or at right angles to the direction of

travel

R

that are on straight roads, not bends

R

that are on the same level as the road, e.g. not

on the pavement

Detecting parking spaces

Objects located above the height range of Active

Parking Assist will not be detected when the

parking space is measured. These are not taken

into account when the parking procedure is cal-

culated, e.g. overhanging loads, tail sections or

loading ramps of goods vehicles.

G

WARNING

If there are objects above the detection range:

R

Active Park Assist may steer too early

R

the vehicle may not stop in front of these

objects

You may cause a collision as a result. There is

a risk of an accident.
If objects are located above the detection

range, stop and deactivate Active Parking

Assist.

For further information on the detection range

(

Y

page 214).

Active Parking Assist does not assist you park-

ing in spaces at right angles to the direction of

travel if:

R

two parking spaces are located directly next

to one another

R

the parking space is directly next to a low

obstacle such as a low curb

R

you park forwards

Active Parking Assist does not assist you park-

ing in spaces that are parallel or at right angles

to the direction of travel if:

R

the parking space is on a curb

R

the system reads the parking space as being

blocked, for example by foliage or grass pav-

ing blocks

R

the area is too small for the vehicle to maneu-

ver into

R

the parking space is bordered by an obstacle,

e.g. a tree, a post or a trailer

Active Parking Assist is switched on automati-

cally when driving forwards. The system is

operational at speeds of up to approximately

22 mph (35 km/h). While in operation, the sys-

tem independently locates and measures park-

ing spaces on both sides of the vehicle.

Active Parking Assist will only detect parking

spaces:

R

parallel or at right angles to the direction of

travel

R

that are parallel to the direction of travel and

at least 59 in (1.5 m) wide

cle

R

that are at right angles to the direction of

travel and at least 39.5 in (1.0 m) wider than

your vehicle

i

Note that Active Parking Assist cannot

measure the size of a parking space if it is at

right angles to the direction of travel. You will

need to judge whether your vehicle will fit into

the parking space.

When driving at speeds below 19 mph

(30 km/h), you will see the parking symbol as a

status indicator in the instrument cluster. When

a parking space has been detected, an arrow

towards the right or the left also appears. By

default, Active Parking Assist only displays park-

ing 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 acknowl-

edge the use of Active Parking Assist by press-

ing the a button on the multifunction steer-

ing wheel. The system automatically determines

whether the parking space is parallel or at right

angles to the direction of travel.

A parking space is displayed while you are driv-

ing past it, and until you are approximately 50 ft

(15 m) away from it.

there is a malfunction in the system or in

the voltage supply.

R

the electrical system in the engine com-

partment, the battery or the fuses have

been tampered with.

R

the battery is disconnected.

R

the accelerator pedal has been depressed,

e.g. by a vehicle occupant.

There is a risk of an accident.

As soon as the parking procedure is complete,

the

Park Assist Switched Off

message

appears and a warning tone sounds. The vehicle

is now parked. The vehicle is kept stationary

without the driver having to depress the brake

pedal. The braking effect is canceled when you

depress the accelerator pedal.

Active Parking Assist no longer supports you

with steering interventions and brake applica-

tions. When Active Parking Assist is finished,

you must steer and brake again yourself.

PARKTRONIC is still available.

Parking tips:

R

The way your vehicle is positioned in the park-

ing space after parking is dependent on vari-

ous factors. These include the position and

shape of the vehicles parked in front and

behind it and the conditions of the location. It

may be the case that Active Parking Assist

guides you too far into a parking space, or not

far enough into it. In some cases, it may also

lead you across or onto the curb. If necessary,

you should cancel the parking procedure with

Active Parking Assist.

R

You can also select preselect transmission

position D. The vehicle redirects and does not

drive as far into the parking space. Should the

transmission change take place too early, the

parking procedure will be canceled. A sensi-

ble parking position can no longer be ach-

ieved from this position.

Exiting a parking space

In order that Active Parking Assist can support

you when you exit the parking space:

R

the border of the parking space must be high

enough at the front and the rear. A curb is too

small, for example.

R

the border of the parking space must not be

too wide, as the position of the vehicle must

not exceed an angle of 45° to the starting

position as it is maneuvering into the parking

space.

R

a maneuvering distance of at least 3.3 ft

(1.0 m) must be available.

Active Parking Assist can only assist you with

exiting a parking space if you have parked the

vehicle parallel to the direction of travel using

Active Parking Assist.

i

If PARKTRONIC detects obstacles, Active

Parking Assist brakes automatically whilst the

vehicle exits the parking space. You are

responsible for braking in good time.

X

Object detection

The rear view camera can detect moving and

stationary objects. If, for example, a pedestrian

or another vehicle is detected, these objects are

marked with bars. The system is only able to

detect and mark stationary objects when your

vehicle is moving. When the vehicle is station-

ary, moving objects can be detected and

marked.

To ensure that you can use the function, it must

be switched on in the multimedia system (see

the separate operating instructions).

360° camera (surround view)

General notes

The 360° camera is a system consisting of four

cameras.

The system processes images from the follow-

ing cameras:

R

Rear view camera

R

Front camera

R

Two side cameras in the exterior mirrors

The cameras capture the immediate surround-

ings of the vehicle. The 360° camera assists

you, for instance when parking or at exits with

reduced visibility.

You can show images from the 360° camera in

full-screen mode or in six different split-screen

views on the multimedia system. A split-screen

view also includes a top view of the vehicle. This

view is calculated from the data supplied by the

installed cameras (virtual camera).

The six split-screen views are:

R

top view and picture from the rear view cam-

era (130° viewing angle)

R

top view and image from the front camera

(130° viewing angle without displaying the

maximum steering wheel angle)

R

top view and enlarged rear view

R

top view and enlarged front view

R

top view and images from the rear-facing side

cameras (rear wheel view)

R

top view and images from the forward-facing

side cameras (front wheel view)

When the function is active and you shift the

transmission from D or R to N, the guide lines

are hidden in the multimedia system.

When you change between transmission posi-

tions D and R, you see the previously selected

front or rear view.

Distances measured by PARKTRONIC will also

be optically displayed:

R

in split screen view as red or yellow brackets

around the vehicle icon in the top view, or

R

at the bottom right as red or yellow brackets

around the vehicle symbol in full-screen mode

The line thickness and color of the brackets

show how far the vehicle is from an object.

R

yellow brackets with thin lines: PARKTRONIC

is active

R

yellow brackets with normal lines: an object is

present in close range of the vehicle

R

red line: an object is present in the immediate

close range of the vehicle

Important safety notes

The 360°camera is only an aid and may show a

distorted view of obstacles, show them incor-

rectly or not at all. The 360°camera is not a

substitute for attentive driving.

You are always responsible for safe maneuver-

ing and parking. When maneuvering or parking,

make sure that there are no persons, animals or

objects in the area in which you are maneuver-

ing.

You are always responsible for safety, and must

always pay attention to your surroundings when

parking and maneuvering. This applies to the

areas behind, in front of and beside the vehicle.

You could otherwise endanger yourself and oth-

ers.

The 360° camera will not function or will func-

tion in a limited manner:

R

if the doors are open

R

if the exterior mirrors are folded in

R

if the trunk lid is open

R

in heavy rain, snow or fog

R

can otherwise injure others or cause damage to

objects or the vehicle.

The guide lines on the multimedia system show

the distances to your vehicle. The distances only

apply to road level.

The cameras in the front and in the rear area are

each protected by a flap. These flaps are opened

when the 360° camera is activated. Observe the

notes on cleaning (

Y

page 363). For technical

reasons, the flaps may remain open briefly after

the 360° camera has been deactivated.

The field of vision and other functions of the

camera system may be restricted due to addi-

tional accessories on the rear of the vehicle (e.g.

license plate holder, bicycle rack).

ATTENTION ASSIST

General notes

ATTENTION ASSIST helps you during long,

monotonous journeys, such as on highways. It is

active in the 37 mph (60 km/h) to 125 mph

(200 km/h) range. If ATTENTION ASSIST

detects typical indicators of fatigue or increas-

ing lapses in concentration on the part of the

driver, it suggests taking a break.

Important safety notes

ATTENTION ASSIST is only an aid to the driver. It

might not always recognize fatigue or increasing

inattentiveness in time or fail to recognize them

at all. The system is not a substitute for a well-

rested and attentive driver.

The functionality of ATTENTION ASSIST is

restricted and warnings may be delayed or not

occur at all:

R

if the length of the journey is less than approx-

imately 30 minutes

R

if the road condition is poor, e.g. if the surface

is uneven or if there are potholes

R

if there is a strong side wind

R

if you have adopted a sporty driving style with

high cornering speeds or high rates of accel-

eration

R

if you are predominantly driving slower than

37 mph (60 km/h) or faster than 125 mph

(200 km/h)

R

if you are driving with the active Steer Assist

of DISTRONIC PLUS

R

if the time has been set incorrectly

R

in active driving situations, such as when you

change lanes or change your speed

The ATTENTION ASSIST tiredness assessment

is deleted and restarted when continuing the

journey, if:

R

you switch off the engine

R

you take off your seat belt and open the driv-

er's door, e.g. for a change of drivers or to

take a break

Displaying the attention level

You can have current status information dis-

played in the assistance menu (

Y

page 269) of

the on-board computer.

X

Select the Assistance display for ATTENTION

ASSIST using the on-board computer

(

Y

page 268).

The following information is displayed:

R

length of the journey since the last break.

R

the attention level determined by ATTENTION

ASSIST (

Attention Level

), displayed in a

bar display in five levels from high to low

R

if ATTENTION ASSIST is unable to calculate

the attention level and cannot issue a warn-

ing, the

message

appears. The bar display then changes the

display, e.g. if you are driving at a speed below

37 mph (60 km/h) or above 124 mph

(200 km/h).

Activating ATTENTION ASSIST

X

Activate ATTENTION ASSIST using the on-

board computer (

The system determines the attention level of

the driver depending on the setting selected:

If

Standard

is selected: the sensitivity with

which the system determines the attention level

is set to normal.

If

Sensitive

is selected: the sensitivity is set

higher. The attention level detected by Attention

228

Assist is adapted accordingly and the driver is

warned earlier.

When ATTENTION ASSIST is deactivated, the

é symbol appears in the multifunction dis-

play in the assistance graphic display.

When ATTENTION ASSIST has been deactivated,

it is automatically reactivated after the engine

has been stopped. The sensitivity selected cor-

responds to the last selection activated (stand-

ard/sensitive).

Warning in the multifunction display

If fatigue or increasing lapses in concentration

are detected, a warning appears in the multi-

function display:

ATTENTION ASSIST Take a

Break!

.

In addition to the message shown in the multi-

function display, you will then hear a warning

tone.

X

If necessary, take a break.

X

Confirm the message by pressing the a

button on the steering wheel.

On long journeys, take regular breaks in good

time to allow yourself to rest properly. If you do

not take a break and ATTENTION ASSIST con-

tinues to detect increasing lapses in concentra-

tion, you will be warned again after 15 minutes

at the earliest. This will only happen if ATTEN-

TION ASSIST still detects typical indicators of

fatigue or increasing lapses in concentration.

If a warning is given in the multifunction display,

the multimedia system offers a service station

search. You can select a service station and

navigation to this service station will then begin.

This function can be activated and deactivated

in the multimedia system.

Traffic Sign Assist

General notes

Traffic Sign Assist displays the maximum speed

permitted to the driver in the instrument cluster.

The data and general traffic regulations stored in

the navigation system are used to determine the

current speed limit.

Traffic Sign Assist is a map-based system, and

for this reason, traffic signs put up temporarily

(e.g. near roadworks) are not detected.

If a traffic sign that is relevant to your vehicle is

passed, the display of the speed limits is upda-

ted.

Traffic signs with a restriction indicated by an

additional sign (e.g. in wet conditions) are also

shown.

The traffic signs are only displayed with the

restrictions if:

R

the regulation must be observed with the

restriction, or

R

Traffic Sign Assist is unable to determine

whether the restriction applies

If Traffic Sign Assist is unable to determine a

maximum permitted speed from any of the avail-

able sources, no speed limit is displayed in the

instrument cluster either.

Traffic Sign Assist is not available in all coun-

tries. In this case, symbol : is shown in the

assistance graphic display (

Y

page 268).

Important safety notes

Traffic Sign Assist is only an aid and is not always

able to correctly display speed limits. Traffic

signs always have priority over the Traffic Sign

Assist display.

The system may be either functionally impaired

or temporarily unavailable if the information in

the digital street map of the navigation system is

incorrect or out of date.

Activating Traffic Sign Assist

X

Activate the Traffic Sign Assist display using

the on-board computer (

Y

page 270).

If you have activated the Traffic Sign Assist dis-

play in the on-board computer, the traffic regu-

lations (speed limits and overtaking restrictions)

are displayed in the instrument cluster for five

seconds respectively. The wrong-way warning

i

The unit for the speed limit (km/h or mph)

depends on the country in which you are driv-

ing. It is generally neither shown on the traffic

sign nor on the instrument cluster but must be

taken into account when observing the max-

imum permitted speed.

Night View Assist Plus

General notes

In addition to the illumination provided by the

normal headlamps, Night View Assist Plus uses

infrared light to illuminate the road. Night View

Assist Plus camera ; picks up the infrared light

and displays a monochrome image in the multi-

function display. The image shown in the display

corresponds to a road lit up by high-beam head-

lamps. This enables you to see the road's course

and any obstacles in good time. When pedes-

trian recognition is active, pedestrians recog-

230

ing

nized by the system are visually highlighted in

color in the Night View Assist Plus display with

small frame corners.

In addition, an infrared camera is integrated into

the radiator trim :. The camera helps detect

pedestrians and animals. Observe the notes on

cleaning the infrared camera (

Y

page 364).

i

Infrared light is not visible to the human eye

and therefore does not glare. Night View

Assist Plus can therefore remain switched on

even if there is oncoming traffic.

Important safety notes

Night View Assist Plus is only an aid and is not a

substitute for attentive driving. Do not rely on

the Night View Assist Plus display. You are

responsible for the distance to the vehicle in

front, for vehicle speed and for braking in good

time. Drive carefully and always adapt your driv-

ing style to suit the prevailing road and traffic

conditions.

The system may be impaired or may not function

if:

R

there is poor visibility, e.g. due to snow, rain,

fog or spray

R

the windshield is dirty, fogged up or covered,

for instance by a sticker, in the vicinity of the

camera

R

the infrared camera in the radiator trim is

dirty, fogged up or obscured

R

on bends, hilltops or downhill gradients

R

at high outside temperatures

Night View Assist Plus cannot display objects

directly in front of or beside the vehicle.

It is possible that, in addition to people and ani-

mals, other objects are also marked or highligh-

ted .

Pedestrian and animal recognition

General notes

Pedestrian or animal recognition may be

impaired or inoperative if:

R

pedestrians or animals are partially or entirely

obscured by other objects, e.g. parked vehi-

cles

R

the silhouette of the pedestrian or of the ani-

mal in the Night View Assist Plus display is

incomplete or interrupted, e.g. by powerful

light reflections

R

pedestrians or animals do not contrast with

the surroundings

R

the camera system no longer recognizes

pedestrians as persons due to special cloth-

ing or other objects

R

pedestrians are not in an upright position, e.g.

sitting, squatting or lying

R

animals are not recognized by the system,

e.g. because of their size or shape

Pedestrian and animal recognition is deactiva-

ted at temperatures above 90 ‡ (32 †). The

spotlight function and automatic delayed

switch-off are then no longer active.
