cles that are in the path of your vehicle for an
extended period of time.
Up to a speed of around 44 mph (70 km/h),
the distance warning function can also react
to stationary obstacles, such as stopped or
parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision, the system will initially alert you both visually
and acoustically.
Autonomous braking function
If the driver does not react to the distance
warning signal in a critical situation, COLLI-
SION PREVENTION ASSIST PLUS can assist
with the autonomous braking function.
The autonomous braking function:
R gives the driver more time to react to criti-
cal driving situations
R can help the driver to avoid an accident or
R reduces the effects of an accident
The autonomous braking function is available in the following speed ranges:
R from 5 mph (7 km/h) to approx. 65 mph
(105 km/h) for moving objects
R from 5 mph (7 km/h) to approx. 31 mph
(50 km/h) for stationary objects
If the autonomous braking function requires a particularly high braking force, preventative
passenger protection measures (PRE-SAFE ®
)
are activated simultaneously.
Adaptive Brake Assist
iObserve the "Important safety notes" sec-
tion ( Ypage 65).
Adaptive Brake Assist provides braking assis-
tance in hazardous situations at speeds
above 4 mph (7 km/h). It uses radar sensor
technology to assess the traffic situation.
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
R intervene unnecessarily
R not intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
GWARNING
Adaptive Brake Assist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R when cornering
As a result, the Adaptive Brake Assist may not intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
Due to the nature of the system, particularly
complicated but non-critical driving condi-
tions may also cause Brake Assist to inter-
vene.
If adaptive Brake Assist is not available due to a malfunction in the radar sensor system, thebrake system remains available with full
brake boosting effect and BAS.
With the help of adaptive Brake Assist, the
distance warning signal can detect obstacles
that are in the path of your vehicle for an
extended period of time.
If adaptive Brake Assist detects a risk of col-
lision with the vehicle in front, it calculates
the braking force necessary to avoid a colli-
sion. If you apply the brakes forcefully, adap-
tive Brake Assist will automatically increase
the braking force to a level suitable for the
traffic conditions.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
70Driving safety systems
Safety

a collision cannot always be avoided, partic-
ularly when approaching at too high a speed.
There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action, provided it is safe to doso.
GWARNING
PRE-SAFE®
Brake cannot always clearly iden-
tify 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 col- lision, 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 approx-
imately 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 vehi-
cle, e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
GWARNING
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 sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
In the event of snowfall or heavy rain, the rec-
ognition can be impaired.
Recognition by the radar sensor system is
also impaired in the event of:
R there is dirt on the sensors or anything else
covering the sensors
R there is interference by other radar sources
R there are 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 cov-ered
R there is 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 dis-
tinguishable from the background
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensors checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.

exhaust system if you use HANDS-FREE
ACCESS. There is a risk of injury. Always
ensure that you only make the kicking move-
ment within the detection range of sensors.
!If the SmartKey is within the rear detec-
tion 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 SmartKey is at least
10 ft (3 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.

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 clear-
ance to the rear of the vehicle. You could
otherwise lose your balance e.g. on ice.
R Always ensure that you only make the kick-
ing movement within the detection range of sensors :.
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. Oth-
erwise, the sensors may not function cor-
rectly.

Exterior lighting
General notes
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switchedon even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations.
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 sym-
metrical 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 asym- metrical low-beam headlamps at a qualified
specialist workshop as soon as possible after
crossing the border again.

Adaptive Highbeam Assist Plus
General notes
With Adaptive Highbeam Assist Plus, you can automatically switch between low-beam, par-
tial high-beam and high-beam headlamps.
Partial high-beam is a form of illumination
whereby the high-beam is directed past other
road users. Other road users are kept out of
the high-beam. This prevents glare. When
there is a vehicle in front, for example, the
high-beam headlamps illuminate the areas to
its right and left, and the vehicle in front is
illuminated by the low-beam headlamps.
The system automatically adapts the low-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the high-beam headlamps.
If the high-beam or partial high-beam are
causing too much reflection from traffic
signs, the lights are automatically dimmed
and glare for the driver caused by the reflec-
tions is thus avoided.
The system's optical sensor is located behind the windshield near the overhead control
panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist Plus does not rec-
ognize road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
Plus may not recognize road users who do
have lights, or may recognize them too late. In
this or similar situations, the automatic high-
beam headlamps will not be deactivated or
will be activated regardless. There is a risk of
an accident.
Always carefully observe the traffic conditions and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist Plus cannot take
into account road, weather or traffic condi-
tions. Adaptive Highbeam Assist Plus is only
an aid. You are responsible for adjusting the
vehicle's lighting to the prevailing light, visi-
bility and traffic conditions.
In particular, the detection of obstacles can
be restricted if there is: R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or the sensors are
obscured

Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and driv-
ing safety systems adjusts automatically
while a certain distance is being driven after
the vehicle has been delivered or after
repairs. Full system effectiveness is not
reached until the end of this teach-in proce-dure.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate for this by applying greater force to the
brake pedal.
The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R You should therefore drive at varying vehi-
cle and engine speeds for the first
1000 miles (1500 km).
R Avoid heavy loads, e.g. driving at full throt-
tle, during this period.
R When shifting gears manually, upshift in
good time, before the tachometer needlereaches Ôof the way to the red area of the
tachometer. R
Do not manually shift to a lower gear to
brake the vehicle.
R Try to avoid depressing the accelerator
pedal beyond the point of resistance (kick-
down).
R All vehicles (except AMG vehicles): ide-
ally, for the first 1,000 miles (1,500 km),
drive in program E.
Additional breaking-in notes for AMG vehi-cles: R Do not drive faster than 85 mph
(140 km/ h)for the first 1,000 miles
(1,500 km).
R Only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R Change gear in good time.
R Ideally, for the first 1,000 miles (1,500 km),
drive in program C.
After 1000 mile s(1500 km), you can increase
the engine speed gradually and accelerate
the vehicle to full speed.
You should also observe these notes on
breaking in if the engine or parts of the drive
train on your vehicle have been replaced.
Always observe the respective speed limits.
Driving
Important safety notes
