If you wish to leave the vehicle or park it,
deactivate DISTRONIC PLUS and secure the
vehicle against rolling away.
If DISTRONIC PLUS detects that the vehicle
in
front is stopping, it brakes your vehicle until
it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
i Depending on the specified minimum
distance, your vehicle will come to a
standstill at a sufficient distance behind the
vehicle in front. The specified minimum
distance is set using the control on the
cruise control lever.
When DISTRONIC PLUS is activated, the
transmission is shifted automatically to
position P if:
R the driver's door is open and the driver's
seat belt is unfastened.
R the engine is switched off, unless it is
automatically switched off by the ECO
start/stop function.
R the hood is opened.

Deactivating DISTRONIC PLUS G
WARNING
DISTRONIC PLUS is deactivated and releases
the brakes if the vehicle is slowed down to a
speed
below 20 mph (30km/h) by the system,
provided that DISTRONIC PLUS does not
detect a vehicle directly in front. At this point,
the driver must apply the brakes in order to
slow down further and bring the vehicle to a
standstill. There are several ways to deactivate
DISTRONIC PLUS:
X
Briefly press the cruise control lever

X Brake, unless the vehicle is stationary.
When you deactivate DISTRONIC PLUS, you
will
see the DISTRONIC PLUS Off message
in the multifunction display for approximately
five seconds.
i The last speed stored remains stored until
you switch off the engine. DISTRONIC PLUS is automatically
deactivated if:
R
you engage the parking brake.
R you are driving slower than
15 mph

or if the vehicle in front is no longer
detected.
R ESP ®

Tips for driving with DISTRONIC PLUS Important safety notes
G
WARNING
The DISTRONIC PLUS works to maintain the
speed
selected by the driver unless a moving
obstacle proceeding directly ahead of it in the
same travel direction is detected (e.g.
following another vehicle ahead of you at your
set distance).
This means that:
R Your vehicle can pass another vehicle after
you have changed lanes.
R While in a sharp turn or if the preceding
vehicle is in a sharp turn, the DISTRONIC
PLUS could lose sight of the preceding
vehicle. Your vehicle could then accelerate
to the previously selected speed.176

Important safety notes G
WARNING
RACE START is only available when SPORT
handling mode is activated. SPORT handling
mode only stabilizes the vehicle to a limited
extent in the event of swerving or wheelspin.
RACE
START should only be used on specially
designated roads. Always adapt your speed
and driving style to the prevailing road and
weather conditions.
i RACE START is only available in AMG
vehicles.
RACE START enables optimal acceleration
from a standing start. The precondition for
this is a suitable high-grip road surface.
Conditions for activation You can activate RACE START if:

WARNING
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured.
PARKTRONIC
is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R shift the transmission to position D, R or N
R release the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18km/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.
Range of the sensors General 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. :
Example: sensors in the front bumper,
left-hand side
The sensors must be free of dirt, ice and
slush. Otherwise, they may not function
correctly.
Clean the sensors regularly, taking
care not to scratch or damage them
(Y page 307). Example: side view
Example: top view184

= Detected parking space on the right
Active Parking Assist is switched on
automatically when driving forwards. The
system is operational at speeds of up to
approximately
22 mph (35 km/h). While in
operation, the system independently locates
and measures parking spaces on both sides
of the vehicle. When driving at speeds below
19 mph (30 km/h), you will see the parking
symbol as a status indicator in the instrument
cluster. By default, Active Parking Assist only
displays parking spaces on the front-
passenger side. Parking spaces on the
driver's side are displayed as soon as the turn
signal on the driver's side is activated. To park
on the driver's side, you must leave the
driver's side turn signal switched on. This
must remain switched on until you
acknowledge the use of Active Parking Assist
by pressing the a button on the
multifunction steering wheel.
When a parking space has been detected, an
arrow towards the right or the left also
appears.
Active Parking Assist will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 59 in (1.5 m) wide
R that are at least 51 in (1.3 m) longer than
your vehicle
A parking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it. Parking G
WARNING
PARKTRONIC and Active Parking Assist are
merely parking aids and may not detect all
obstacles. They do not relieve you of the
responsibility of paying attention.
