As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving.
In particular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rvisibility is poor, e.g. due to fog, heavy rain or
snow
Rthere is a narrow vehicle traveling in front, e.g.
a motorcycle or bicycle
Rthe road has very wide lanes
Rthe road has narrow lanes
Ryou are not driving in the middle of the lane
Rthere are barriers or other road boundaries
iUSA only:
This device has been approved by the FCC as
a "Vehicular Radar System". The radar sensor
is intended for use in an automotive radar
system only. Removing, tampering with, or
altering the device will void any warranties,
and is not permitted by the FCC. Do not tam-
per with, alter, or use in any non-approved
way.
Any unauthorized modification to this device
could void the user’s authority to operate the
equipment.
General notes
Blind Spot Assist uses a radar sensor system to
monitor both the left and right sides of your
vehicle. It supports you from a speed of approx-
imately 20 mph (30 km/h). A warning display in
the exterior mirrors draws your attention to
vehicles detected in the monitored area. If you
then switch on the corresponding turn signal to change lanes, you will also receive a visual and
audible collision warning. For this purpose, Blind
Spot Assist uses sensors in the rear bumper.
Monitoring range of the sensors
Blind Spot Assist monitors the area up to 10 ft
(3 m) behind your vehicle and directly next to
your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side
of their lane.
Due to the nature of the system:
Rwarnings may be issued in error when driving
close to crash barriers or similar solid lane
borders.
Rthe warning is canceled when driving for an
extended period next to long vehicles, such as
trucks.
The two sensors for Blind Spot Assist are inte-
grated into the sides of the rear bumper. Make
sure that the bumper is free of dirt, ice or slush
in the vicinity of the sensors. The radar sensors
must not be covered, for example by rear bicycle
racks or overhanging loads. Following a severe
impact or in the event of damage to the bump-
ers, have the function of the radar sensors
checked at a qualified specialist workshop.
Blind Spot Assist may otherwise not work prop-
erly.

!A function or performance test should only
be carried out on a two-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
The all-wheel drive system ensures that all four
wheels are permanently driven. The all-wheel
drive system improves vehicle traction together
with ESP
®and 4ETS if a drive wheel spins due to
insufficient grip.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far as
necessary when pulling away.
RTake your foot off the accelerator, slowly,
while the vehicle is in motion.
The permanent all-wheel drive system can nei-
ther reduce the risk of accident nor override the
laws of physics if you fail to adapt your driving
style or if you are inattentive. The all-wheel drive
system cannot take into account road, weather
or traffic conditions. The all-wheel drive system
is only an aid. You are responsible for maintain-
ing a safe distance to the vehicle in front, for
vehicle speed, for braking in good time and for
staying in lane.
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains
(
Ypage 264). Only in this way can the maximum
effect of all-wheel drive be achieved.
For information on driving off-road, see
(
Ypage 137).
PARKTRONIC
Important safety notes
!When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. PARKTRONIC
does not detect such objects when they are in the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes on a truck
or a pneumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain. PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and audi-
bly the distance between your vehicle and an
object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting a parking
space. Ensure that the areas in front, behind and
to the side of the vehicle are safe before maneu-
vering, parking or pulling away. There must not
be any persons, animals or objects in the area in
which you are maneuvering.
PARKTRONIC does not take into account any
persons or objects located below or above the
detection range. As a result, PARKTRONIC can-
not warn you about objects in this area.
PARKTRONIC is activated automatically when
you:
Rswitch on the ignition
Rshift the transmission to position D,Ror N
Rrelease the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.

The sensors must be free from dirt, ice or slush.
Otherwise, they may not function correctly.
Clean the sensors regularly, taking care not to
scratch or damage them (

If there is an obstacle within this range, the rel-
evant warning displays light up and a warning
tone sounds. If the distance falls below the min-
imum, the distance may no longer be shown.
Warning displays

The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is located on
the dashboard above the center air vents. The
warning display for the rear area is located on
the headliner in the rear compartment.
The warning display for each side of the vehicle
is divided into five yellow and two red segments.
PARKTRONIC is operational if yellow segments
showing operational readiness =light up.
The selected transmission position and the
direction in which the vehicle is rolling deter-
mine which warning display is active when the
engine is running.

One or more segments light up as the vehicle
approaches an obstacle, depending on the vehi-
cle's distance from the obstacle.
From the:
Rsixth segment onwards, you will hear an inter-
mittent warning tone for approximately two
seconds.
Rseventh segment onwards, you will hear a
warning tone for approximately two seconds.

Rear view camera
Important safety notes
The rear view camera is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering and parking. When maneu-
vering or parking, make sure that there are no
persons, animals or objects in the area in which
you are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function in
a limited manner:
Rthe rear door is open
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent light or LED
lighting (the display may flicker)
Rif there is a sudden change in temperature,
e.g. when driving into a heated garage in win- ter
Rif the camera lens is dirty or obstructed
Rif the rear of your vehicle is damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose
