ESTART
Important safety notes i
Observe the safety notes for the SPORT
handling mod e(Ypage 70).
RAC ESTART is intended solely for activation
on dedicated race circuits.
RACE START enables optimal acceleration
from astandin gstart .The precondition for
this is asuitable high-grip road surface.
i RACE START is only available in AMG
vehicles.
Conditions for activation You can activat
eRACE START if:
R the doors are closed.
R the engine is runnin gand it has reached an
operating temperature of approximately
176 ‡(80 †). This is the case when the
engine oil temperature in the multifunction
display stops flashing.
R SPORT handling mode is activated.
(Y page 70)
R the steerin gwheel is in the straight-ahead
position
R the vehicle is stationary and the brake
pedal is depressed (left foot).
R the transmission is in position D.

Load compensation
The vehicle can compensat
edifferences in
th ev ehicle level by raisin gorlowering the
rear axle. This is the case, for example, if
people get out or if luggage is being loaded.
Load compensation takes place if:
R ad oor or the trunk lid/tailgate is opened
R the parked vehicle is unlocked
For larger level changes, the engine must be
running. 4MATIC (permanent four-wheel drive)
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic
conditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front,f or vehicle speed, for braking in good
time and for staying in your lane.
If ad rive wheel spins due to insufficien tgrip:
R Only depress the accelerator peda lasfar
as necessary when pulling away.
R Accelerate less when driving.
! Never tow the vehicl ewith one axle
raised. This may damage the transfer case.
Damag eofthis sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remai neithe ront he ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
4MATIC ensures that allf our wheels are
permanently driven. Together with ESP ®
,it
improves the traction of you rvehicle
whenever adrive wheel spins due to
insufficient grip. PARKTRONIC
Important safet ynotes PARKTRONIC is an electronic parkin
gaid with
ultrasonic sensors. It indicates visually and
audibly the distanc ebetween your vehicle
and an object.
PARKTRONIC is only an aid. It is not a
replacemen tfor your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting aparkin gspace. When
maneuvering, parkin gorpulling out of a
parkin gspace, make sure that ther eare no
persons, animals or objects in the area in
which you are maneuvering.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detec tsuch objects
when they are in th eimmediat evicinity of
th ev ehicle. You could damag ethe vehicle
or the objects.
The sensors may not detect snow and other
objectst hat absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or apneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release 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. Driving systems

signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing the 000C

R
give an unnecessary warning
R not 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. G
WARNING
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
Keeping Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. Lane
Keeping Assist is merely an aid. You are
responsible for the distance to the vehicle in
front,f or vehicle speed, for braking in good
time and for staying in your lane.
The Lane Keeping Assist does not keep the
vehicle in the lane.
The system may be impaired or may not
function if:
R there is poor visibility, e.g. due to
insufficient illumination of the road, or due
to snow, rain, fog or spray
R there is glare, e.g. from oncomingt raffic,
the sun or reflections (e.g. when the road
surface is wet)
R the windshield is dirty, fogged up, damaged
or covered, for instancebyas ticker, in the
vicinity of the camera
R there are no, several or unclear lane
markings for alane, e.g. in areas with road
construction work
R the lane markings are worn away,d ark or
covered up, e.g. by dirt or snow Driving systems

R there are strong shadows cast on the lane
General notes Lane Keeping Assist monitors the area in
front of yourv ehicle with camera 001A,which is
mounted at the top of the windshield. Lane
Keeping Assist detects lane markings on the
road and warns you before you leave your
lane unintentionally.
If you have chosen the function DisplayUnit Speed-/Odometer: (Y

Active Blind Spot Assist Genera
lnotes
Active Blind Spot Assis tuses aradar sensor
system, pointed toward the rear of the
vehicle, to monitor the area to the sides of the
vehicle which the driver is unable to see. A
warning displayint he exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lane, you
will also receive an optical and audible
warning. If arisk of lateral collision is
detected, corrective braking may help you
avoid acollision. Before acourse-correcting
brake application, Active Blind Spot Assist
evaluates the space in the direction of travel
and at the sides of the vehicle. For this, Active
Blind Spot Assist uses radar sensors which
are pointed in the direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be:
R activated(Y page 232)
R operational
Important safety notes
Active Blind Spot Assist is only an aid and is
not asubstitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with alarge speed
differential and overtak eyour vehicle As
aresult, Active Blind Spot Assist may
neither give warnings nor intervene in such
situations. There is arisk of an accident.
Always observe the traffic conditions
carefully, and maintain asafe lateral distance.

WARNING
Ac ourse-correctingb rake application cannot

an accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes acourse-correcting brake
application. Always maintain asafe distance
at the sides. If Active Blind Spot Assist detect
sarisk of a
lateral collision in the monitoring range, a course-correcting brake application is carried
out. This is meant to assist you in avoiding a
collision.
If
ac ourse-correcting brake application
occurs, red warning lamp 001Aflashes in the

In very rare cases, the system may make an
inappropriate brake application. An
inappropriate course-correcting brake
application may be interrupted at any time if
you steer slightly in the opposite direction or
accelerate, for example.
The course-correcting brake application is
available in the speed range between
20 mph (30 km/h) and 120 mph (200 km/h).
Either no braking application, or acourse-
correcting brake application adapted to the
driving situation occurs if:
R there are vehicles or obstacles, e.g. crash
