Parking Guidance
Important safety notes
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to measure
the road on both sides of the vehicle. Asuitable
parking space is indicated by the parking sym-
bol. You receive steering instructions when
parking. You can also still use Active Parking
Assist PARKTRONIC (
Ypage 149).
Parking Guidance is only 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 there are no per-
sons, animals or object sinthe maneuvering
area when you are maneuvering or parking.
GWARNING
If object sare located above or below the
detection range, Active Parking Assist may
steer too early. This could cause acollision.
There is arisk of an accident.
Do not use Active Parking Assist in these
types of situation.
!If they cannot be avoided, drive over obsta-
cles such as curbs slowly and at an obtuse
angle. Otherwise, you may damage the
wheels or tires.
If Active Parking Assist PARKTRONIC is deacti-
vated, Parking Guidance is also unavailable.
Parking Guidance may also display spaces not
suitable for parking, e.g.:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Use Parking Guidance for parking spaces:
Rparalleltot he direction of travel
Ron straight roads, not bends
Rthat are on the same level as the road, i.e. not
on the pavement, for example. Parking Guid-
ance may not detect flat curbs
152Driving systems
Driving and parking

Parking tips:
Ron narrow roads, drive as closely as possible
past the parking space
Rparking spaces that are littered or overgrown
might be identified or measured incorrectly
Rparking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly
Rsnowfall or heavy rain may lead to aparking
space being measured inaccurately
Rpay attention to the Active Parking Assist
PARKTRONIC warning messages during the
parking procedure (
Ypage 151)
Rwhen transportin gaload which protrudes
from your vehicle, you should not use Parking
Guidance
Rnever use Parking Guidance with snow chains
or an emergencys pare wheel fitted
Rmake sure that the tire pressures are always
correct. This hasadirect effect on the steer-
ing instructions
Rthe 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 fronta nd
behind it and the conditions of the location. In
some cases, Parking Guidance may guide you
too far or not far enough into aparking space.
In some cases, it may also lead you across or
ont othe curb. If necessary, cancel the park-
ing procedure with Parking Guidance.
Detecting parking spaces

Important safety notes
ATTENTION ASSIST helps yo uduring long,
monotonous journeys, such as on highways .Itis
active in the rang ebetween 50 mph (80 km/h)
and 112 mph (180 km/h).
If ATTENTION ASSIST detects typica lindicators
of fatigueori ncreasing lapsesinc oncentration
on the part of the driver, it suggests yo utake a
break.
ATTENTION ASSIST assesses your level of fati-
gueorl apsesinc oncentration by taking the fol-
lowing criteria into account:

acteristics
Rjourney details, e.g. time of daya nd length of
