Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
If the vehicle in front has been detected and
is shown in the multifunction display, you can
also activate DISTRONIC PLUS when driving
at speeds below 20 mph (30km/h). If the
vehicle in front is no longer detected and
displayed, for example because it has
changed lanes, DISTRONIC PLUS is
deactivated. You will hear awarning tone if
this is the case.
i If you do no tfully release the accelerator
pedal, the DISTRONIC PLUS Passive message appears in the multifunction
display. The set distance to a slower-
moving vehicle in front will then not be
maintained. You will be driving at the speed
you determine by the position of the
accelerato rpedal.

If the vehicle in fron tofyou is stationary, you
can only activate DISTRONIC PLUS once your
vehicle is stationary as well.
i DISTRONIC PLUS can only be activated at
under 20 mph (30km/h) if a vehicle in front
has been detected. Therefore, the
DISTRONIC PLUS distance display in the
instrumen tcluster should be activated
(Y page 276).
i You can use the cruise control lever to set
the stored speed and the control on the
cruise control lever to set the specified
minimum distance (Y page 204).
Activating at the current speed/last
stored speed G
WARNING
If you call up the stored speed and it differs
from the current speed, the vehicle
accelerates or decelerates. If you do not know
the stored speed, the vehicle could accelerate
or brake unexpectedly. There is a risk of an
accident.
Pay attention to the road and traffic
conditions before calling up the stored speed.
If you do not know the stored speed, store the
desired speed again. Driving systems

DISTRONIC PLUS is activated. The first
time it is activated, the current speed is
stored. Otherwise, it sets the vehicle cruise
speed to the previously store dvalue.

If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you 0003or press it up 0002or down 0021.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control. If DISTRONIC PLUS detects that the vehicle
in fron
thas slowed down, it brakes your
vehicle .Inthis way, the distance you have
selected is maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up
to the speed you have stored.
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
R you are driving faster than 40mph
(60 km/h)
R DISTRONIC PLUS is maintaining the
distance to a vehicle in front
R you switch on the appropriate turn signal
R DISTRONIC PLUS does not detect a danger
of collision
If these conditions are fulfilled, your vehicle
is accelerated. Acceleration will be
interrupted if changing lanes takes too long
or if the distance between your vehicle and
the vehicle in front becomes too small.
i When changing lanes, DISTRONIC PLUS
monitors the left lane on left-hand drive
vehicles and the right lane on right-hand
drive vehicles.

HOLD function
Important safety notes G
WARNING
When leaving the vehicle, it can still roll away
despite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply.
R the HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
R the electrical system in the engine
compartment, the battery or the fuses have
been tampered with.
R the battery is disconnected
There is a risk of an accident. If you wish to exit the vehicle, always turn off
the HOLD function and secure the vehicle
against rolling away.
! If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automatically in certain situations. To
prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similar situations:
R when towing the vehicle
R in the car wash
Deactivate the HOLD function (Y page 212).
General notes The HOLD function can assist the driver in the
following situations:
R
when pulling away, especially on steep
slopes
R when maneuvering on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
i Do not use the HOLD function when
driving off-road, on steep uphill or downhill
gradients or on slippery or loose surfaces.
The HOLD function cannot hold the vehicle
on such surfaces.
Activation conditions You can activate the HOLD function if:
R
the vehicle is stationary
R the engine is running
R the driver's door is closed or your seat belt
is fastened
R the electric parking brake is released
R the transmission is in position D,Ror N

Driving systemsDriving and parking

Parking tips:
R
On narrow roads, drive as close to the
parking space as possible.
R Parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 219) warning messages during the
parking procedure.
R When transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R Never use Active Parking Assist when snow
chains are installed.
R Make sure that the tire pressures are
always correct. This has adirec tinfluence
on the parking characteristics of the
vehicle.
General notes Active Parking Assist is an electronic parking
aid with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
As
uitable parking space is indicated by the
parking symbol. Active steering intervention
can assis tyou during parking.
You may also use PARKTRONIC
(Y page 217). When PARKTRONIC is switched
off, Active Parking Assist is also unavailable.
Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Detecting parking spaces G
WARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident. If there are objects above the detection range,
stop and deactivate Active Parking Assist.
Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some circumstances, Active
Parking Assist may therefore guide you into
the parking space too early. 0002
Detected parking space on the left

0021 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 000Bbutton on the
multifunction steering wheel.
When a parking space has been detected, an
arrow towards the right or the left also
appears. 222

Important safety notes The rear view camera is only an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering and
parking. When maneuvering or parking, make sure that there are no persons, animals or
objects in the area in which you are
maneuvering.
Under the following circumstances, the rear

R if the area is lit by fluorescent light or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged.In
this event, have the camera positio nand
setting checked at a qualified specialist
workshop.
