R you are driving at less than 20 mph
(30 km/h)
R Blind Spot Assist is deactivated
R Blind Spot Assist is malfunctioning
R there is no clear warning, depending on the
situation
Blind Spot Assist is active from a speed of
20 mph (30 km/h). If a vehicle is detected in
the blind spot monitoring range, red warning
lamp 0043on the corresponding side lights up.
This warning occurs when a vehicle enters the blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 14 mph (22 km/h).
Yellow indicator lamp 0043goes out if reverse
gear is engaged. Blind Spot Assist is then
deactivated.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Collision warning
If a vehicle is detected in the monitoring range of Blind Spot Assist and you switch on the
corresponding turn signal, a double warning
tone sounds once. Red warning lamp 0043

A Lane Keeping Assist warning is suppressed if:
R a driving safety system intervenes, such as
ABS, BAS or ESP ®
.
R you have set the turn signal and a lane

ings are suppressed for a certain period of
time.
R you accelerate hard, e.g. kickdown on vehi-
cles with an automatic transmission.
R you brake hard.
R you steer actively, e.g. swerve to avoid an
obstacle or change lane quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when nec-

R the system recognizes solid lane markings. Warnings are given later if:
R the road has narrow lanes.
R you cut the corner on a bend. PARKTRONIC
General notes PARKTRONIC is an electronic parking aid. The
system is equipped with ultrasonic sensors inthe front and rear bumpers to monitor the
area around your vehicle. PARKTRONIC indi-
cates visually and audibly the distance
between your vehicle and an object.
Your vehicle features two separate sound
emitters with different frequencies for the
warning tones. The warning ranges in front of
and behind the vehicle are indicated by dif-
ferent warning tones.
PARKTRONIC is activated automatically when you:
R turn the key to position 2in the ignition lock
R release the parking brake and
R move the selector lever to D,Nor R
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h) . PARKTRONIC is reactiva-
ted at speeds below 10 mph (16 km/h).
Important safety notes PARKTRONIC is only an aid. It cannot replace
your own awareness of the immediate sur-
roundings. You are responsible for safe
maneuvering, parking and pulling away. Whenmaneuvering, parking and pulling away, make
sure that there are no persons, animals or
objects in the maneuvering area.
! Pay particular attention to obstacles
above or below the sensors when parking,
such as flower pots or trailer towbars.
PARKTRONIC does not recognize such
objects when they are in the immediate
vicinity of the vehicle. You could damage
the vehicle or objects. Driving systems

Important safety notes !
Objects that are not at ground level
appear further away than they actually are, for example:
R the bumper of the vehicle parked behind
R the drawbar of a trailer
R the ball coupling of a trailer tow hitch
R the tail-end of a truck
R slanted posts Only use the image from the rear view cam-
era as a guide. You may otherwise damageyour vehicle and/or the object.
The rear view camera is only an aid. It cannot

Avoid driving at high engine speeds. This
unnecessarily increases the fuel consumption of your vehicle and harms the environment asa result of increased emissions.
The red band in the tachometer indicates the engine's overrevving range.
To protect the engine, the fuel supply is inter-
rupted when the red band is reached. Outside temperature
You should pay special attention to road con-
ditions when temperatures are around the
