Important safety notes 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 185). G
WARNING
Parking Guidance is merely an aid and may
recommendp arking 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
WARNING
Objectsl ocated 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 Driving systems
189Driving and parking

might therefore issu
esteering instructions
too soon. This may leadtoac ollision. For this
reason, you should avoi dusing Parking Guid-
ance in such situations. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
When PARKTRONIC is deactivated, Parking
Guidance is alsou navailable.
Use Parking Guidance for parking spaces:
R that are paralleltot he directionoftravel
R that are on straight roads, not bends
R that are on the same leve lasthe road ,i.e.
not on the pavement, for example. Parking
Guidance may not detect flat kerbs
Parking tips:
R on narrow roads, drive pastt he 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 aparking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 187) warning messages during the
parking procedure.
R when transporting aload which protrudes
from your vehicle, you must not use Parking
Guidance.
R never use Parking Guidance with snow
chains or an emergency spare wheel fitted.
R make sure that the tyre pressures are
always correct.T his hasadirec teffect on
the steering instructions.
R the wayy ourv ehicle is positioned in the
parkin gspace after parkin gisdependent
on various factors. These include the posi-
tion 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
ap arking space. In some cases, it may also lead you across or onto the kerb. If neces-
sary, cancel the parking procedure with
Parking Guidance.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at
as harp angle. Otherwise, you may damage
the wheels or tyres.
Detecting parking spaces Example: vehicles with automatic transmission
:
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Parking Guidance is automaticallya ctivated
when you drive forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of the vehicle. When
driving at speeds below 30 km/h ,you will see
parking symbol ;asastatus indicator in the
instrument cluster.
When aparking space has been detected, an
arrow towards the right =or the left :also
appears. Parking Guidance only displays
parking spaces on the front-passenger side
as standard. Parking spaces on the driver's
side are displayed as soon as the turn signal
on the driver's side is activated. To park on
the driver's side, you must leave the driver's
side turn signal switched on until you have
engaged reverse gear. 190

Genera lnotes The Lane Tracking package consists of Blind
Spot Assist (Y page 196)and Lane Keeping
Assist (Y page 198). Blind Spot Assist Important safet
ynotes
Blind Spot Assist uses aradar senso rsystem
to monitor th eareas on bot hside sofy our
vehicle. Blind Spot Assis tprovide sassistance
at speeds higher than 30 km/h. Awarning
display in the exterior mirrors draw syour
attention to detected vehicles in the moni-
tored area .Ifyou then switch on the corre-
sponding turn signa ltochange lane, you will
alsor eceive avisual and acoustic collision
warning. The Blind Spot Assist monitoring
system usess ensors in the rear bumper. G
WARNING
Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some vehi-
cles and is no substitute for attentive driving.
Blind Spot Assist cannot detect road and traf-
fic conditions. It may fail to detect narrow
vehicles, such as motorcycle sorbicycles, or
only detect them too late.
Monitoring may be affected by dirty sensors,
strong spray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
yours urroundings. Otherwise, you may fail to
recognise danger sintime, caus eanaccident
and injure yourself and others.
The radar sensor system is automatically
deactivate dnearradio telescope facilities
(Y page 345).
For Blin dSpotA ssist to assist you when driv-
ing, the radar sensor system must be activa-
ted (Y page 229) and operational.
Monitoring range of the sensors
Blind Spot Assist monitors the area up to
three metres behind your vehicle and directly
next to your vehicle, as shown in the diagram. 196
Driving systemsDriving and parking

Example: Coupé
G
WARNING
Blind Spo tAssist monitors certain areas in the
immediate vicinity of your vehicle. Vehicles
that approach and drive past at high speeds
are not detected. There is no displaya nd no
warning.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in astaggered formation in
different lanes. This may be the case if vehi-
cles are driving at the edge of their lane that
is furthest awayf rom your vehicle.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourselfa nd others.
If the lanes ar enarrow ,the system may be
unable to distinguish the neighbouring lane
from the one beyond it. For this reason, vehi-
cles in the farther lane may be indicated,
especiallyift he vehicles are driving in astag-
gered formation in different lanes. In particu-
lar, this may be the case if the vehicles are
driving at the edge of their lane nearest your
vehicle. Due to the nature of the system:
R
warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R warnings may be interrupted when driving
alongside particularly long vehicles, for
example lorries, for aprolonged time.
The two sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free of dirt, ice
or slush around the sensors. For example, the
radar sensors must not be covered by cycle
racks or overhanging loads. Following a
severe impact or in the event of damage to
the bumpers, have the function of the radar
sensors checked at aqualified specialist
workshop, e.g. aMercedes-Ben zService
Centre. Blind Spot Assist may otherwise not
work properly.
Indicator and warning display :
Yellow indicator lamp/red warning lamp
If Blind Spot Assist is switched on, indicator
lamp :in the exterior mirror slights up yel-
low up to aspeed of 30 km/h. At speeds
above 30 km/h, the indicator lamp goes out
and Blind Spot Assist is operational.
If av ehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
spondin gside lights up in red. This warning is
alway semitted when avehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake avehicle, Driving systems
