4MATIC (permanent four-wheel drive)
4MATI Censures that all four wheels are perma-
nently driven. Together with ESP®,iti mproves
the traction of your vehicle whenever adrive
wheel spins due to insufficien tgrip.
If you fail to adapt your driving style, 4MATI Ccan
neither reduce the risk of accident nor override the laws of physics. 4MATI Ccannot take
account of road, weather and traffic conditions.
4MATI Ciso nly an aid. You are responsible for
the distanc etothe vehicle in front, for vehicle speed, for braking in good time and for staying in
your lane.
If
ad rive wheel spins due to insufficien tgrip:
ROnly depress the accelerator pedal as far as
necessary when pulling away.
RAccelerate less when driving.
!Never tow the vehicle with one axle raised.
This may damage the transfer case. Damage
of this sort is not covered by the Mercedes-
Benz Limited Warranty. All wheels must
remain either on the ground or be fully raised.
Observe the instruction sfor towing the vehi-
cle with all wheels in full contact with the
ground.
iIn wintry driving conditions, the maximum
effect of 4MATI Ccan only be achieved if you
use winter tires (M+S tires), with snow chains
if necessary.
PARKTRONIC
Important safety notes
PARKTRONIC is an electronic parking aid with
ultrasonic sensors.Itm onitors the area around
your vehicle using six sensors in the front
bumper and six sensors in the rear bumper.
PARKTRONIC indicates visually and audibly the
distanc ebetween your vehicle and an object.
PARKTRONIC is only an aid. It is not areplace-
ment for your attention to your immediate sur-
roundings. You are alwaysr esponsible for safe
maneuvering, parking and exitin gaparking
space. When maneuvering, parking or pulling
out of aparking space, make sure that there are
no persons, animals or object sinthe area in
which you are maneuvering.
!When parking, pay particular attention to
object sabove or below the sensors,s uch as
flower pots or trailer drawbars. PARKTRONIC
does not detect such object swhen they are in
the immediate vicinityoft he vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
object sthat absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes on atruck
or ap neumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.

sound waves.
XSee if PARKTRONIC functions in adifferent location.
Active Parking Assist
General notes
Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. Aparking symbol indicates
as uitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting aparking
space. You may also use PARKTRONIC
(
Ypage 174).
Important safety notes
Active Parking Assist is merely 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 no persons, ani-
mals or object sare in the maneuvering range.
When PARKTRONIC is switched off, Active Park-
ing Assist is also unavailable.
GWARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
result inacollision with another road user.
There is arisk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
!If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist 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
Parking tips:
ROn narrow roads, drive as close to the parking
space as possible.
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.

parking space completely. This is useful, for
example when you recognize that it is already
possible to pull out of the parking space.

Lane Keeping Assist
General notes
Lane Keeping Assist monitor sthe area in front of
your vehicle by means of multifunction cam-
era :which is attached behind the top of the
windshield. Active Lane Keeping Assist detects
lane markings on the road and can warn you
before you leave your lane unintentionally. This function is available in the range between
40 mph and 120 mph (60 km/h and 200 km/h).
Aw
arning may be given if afront wheel passes
over alane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 seconds.
Important safety notes
GWARNING
Lane Keeping Assist may not always clearly
recognizel ane markings.
In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot give awarning
There is arisk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
ar isk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account the
road, traffic and weather conditions. Lane Keep- ing Assist is merely an aid. You are responsible
for the distance to the vehicle in front,f or vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
The Lane Keeping Assist does not keep the vehi-
cle in the lane.
The system may be impaired or may not function
if:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncomingt raffic, the
sun or reflection s(e.g. when the road surface
is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instancebyas ticker, in the vicin-
ity of the camera

The detection of obstacles can be impaired in
the case of:
Rthere is dirt on the sensors or anything else
coveringthe sensors
Rpoor visibility, e.g. due to rain, snow or spray
Vehicles in the monitoring range are then not
indicated.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
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 there are vehicles at the inner edge of
your 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.
Rwarnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for aprolonged time.
Warning display
:Warning display
Active Blind Spot Assist is not operational at
speeds below approximately 20 mph (30 km/h).
Vehicles in the monitoring range are then not
indicated.

monitoring range at speeds above 20 mph
(3 0k m/ h),w arnin glamp :on the correspond-
ing side lights up red. This warnin gisalways
emitted when avehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake avehicle, the warnin gonly
occurs if the differenc einspeed is less than
7m ph (12 km/h). If you select the reverse gear, Active Blind Spot
Assis
tisnot operational.
The brightness of the warnin glamps is auto-
matically adapted to the brightness of the sur-
