Always apply the brakes yourself and try to
take evasive action, provided it is safe to do
so. G
WARNING
PRE-SAFE ®
Brake cannot always clearly
identify objects and complex traffic
conditions.
In these cases, PRE-SAFE ®
Brake may:
R give an unnecessary warning and then
brake the vehicle
R not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE ®
Brake warns you. Terminate the
intervention in a non-critical driving situation.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a
collision, you must apply the brakes yourself.
PRE-SAFE ®
Brake can also brake the vehicle
automatically under the following conditions:
R the driver and front-passenger have their
seat belts fastened
and
R the vehicle speed is between
approximately 4 mph (7 km/h) and
124 mph (200 km/h)
At a speed of up to approximately 44 mph
(70 km/h), PRE-SAFE ®
Brake can also detect:
R stationary objects in the path of your
vehicle, e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle G
WARNING
PRE-SAFE ®
Brake does not react:
R to small people, e.g. children
R to animals
R to oncoming vehicles
R to crossing traffic
R when cornering As a result, PRE-SAFE
®
Brake may neither
give warnings nor intervene in all critical
situations. There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In the event of snowfall or heavy rain, the
recognition can be impaired.
Recognition by the radar sensor system is
also impaired in the event of:
R dirt on the sensors or anything else
covering the sensors
R interference by other radar sources
R strong radar reflections, for example in
parking garages
R a narrow vehicle traveling in front, e.g. a
motorbike
R a vehicle traveling in front on a different line
relative to the center of your vehicle
Recognition by the camera system is also
impaired in the event of:
R dirt on the camera or if the camera is
covered
R glare on the camera system, e.g. from the
sun being low in the sky
R darkness
R if:
-pedestrians move quickly, e.g. into the
path of the vehicle
- the camera system no longer recognizes
a pedestrian as a person due to special
clothing or other objects
- a pedestrian is concealed by other
objects
- the typical outline of a person is not
distinguishable from the background
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
Following damage to the windshield, have the
configuration and operation of the camera Driving safety systems

Important safety notes G
WARNING
The vehicle's exhaust system may be very hot.

ACCESS. There is a risk of injury. Always
ensure that you only make the kicking
movement within the detection range of
sensors. Trunk

!
If the key is within the rear detection
range of KEYLESS-GO, the following
situations, for example, could lead to the
unintentional opening of the trunk:
R using a car wash
R using a power washer
Make sure that the key is at least 6.5 ft
(2 m) away from the vehicle.
General notes With KEYLESS-GO and HANDS-FREE
ACCESS, you can open or close the trunk lid
or stop the procedure without using your
hands. This is useful if you have your hands
full. To do this, make a kicking movement
under the bumper with your foot.
Observe the following points:
R Carry your KEYLESS-GO key about your
person. The KEYLESS-GO key must be in
the rear detection range of the vehicle.
R When making the kicking movement, make
sure that you are standing firmly on the
ground and that there is sufficient
clearance to the rear of the vehicle. You
could otherwise lose your balance e.g. on
ice. R
Always ensure that you only make the
kicking movement within the detection
range of sensors 0043.
R Stand at least 12 in (30 cm) away from the
rear area while doing so.
R Do not come into contact with the bumper
while making the kicking movement. Otherwise, the sensors may not function
correctly.
R HANDS-FREE ACCESS does not function
when the engine is started.
R If a KEYLESS-GO key is within the rear
detection range of KEYLESS-GO, HAND-
FREE ACCESS could be triggered. The trunk
lid could thus be opened or closed
unintentionally, for example, if you:
- set something down or lift something up
behind the vehicle.
- polish the rear of the vehicle.
Do not carry the KEYLESS-GO key about
your person in these situations or in
situations similar to these. This will prevent
the unintentional opening/closing of the
trunk.
R Dirt caused by road salt around
sensors 0043may restrict functionality.
R Using the HANDS-FREE ACCESS with a
prosthetic leg may restrict functionality.

General notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched on even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations. Driving abroad
Symmetrical low-beam headlamps Switch the headlamps to symmetrical low
beam in countries in which traffic drives on
the opposite side of the road from the country
where the vehicle is registered. This prevents
glare to oncoming traffic. When using
symmetrical lights, the edge of the road is not
lit as widely and as far ahead as normal.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
Asymmetrical low beam Have the headlamps converted back to
asymmetrical low-beam headlamps at a
qualified specialist workshop as soon as
possible after crossing the border again. Setting the exterior lighting
