driving off and the front passenger or a rear
passenger door is open
The marker for the set speed on the
speedometer dial go out, an acoustic signal
sounds, and the message DISTRONIC PLUS
Off appears in the multifunction display for
approximately 5 seconds. G
Warning!
The DISTRONIC PLUS switches off and
releases the brakes when the vehicle
decelerates below the minimum speed of
20 mph (30 km/h) by operation of the system
unless the DISTRONIC PLUS detects a vehicle
directly ahead of you. At that time the driver
must apply the brakes in order to reduce
vehicle speed further or bring it to a stop.
Depressing the accelerator pedal does not
deactivate the DISTRONIC PLUS. After a brief
acceleration (e.g. for passing), the
DISTRONIC PLUS will resume the last set
speed.
Setting the following distance in
DISTRONIC PLUS You can set the specified following distance
for the DISTRONIC PLUS by varying the time
setting between 1.0 and 2.0 seconds. Using
this time setting and the current speed of
your vehicle, the DISTRONIC PLUS calculates
and sets the required following distance to
the preceding vehicle.
The set distance will be shown in the
multifunction display.
G
Warning!
It is up to the driver to exercise discretion to
select the appropriate setting given road
conditions, traffic, driver’s preferred driving
style and applicable laws and driving
recommendations for safe following distance. X
Increasing distance: Turn distance
setting switch : in direction of arrow ;.
Increasing the distance setting tells the
DISTRONIC PLUS to maintain a greater
following distance to the preceding vehicle.
X Decreasing distance: Turn distance
setting switch : in direction of arrow =.
Decreasing the distance setting tells the
DISTRONIC PLUS to maintain a shorter
following distance to the preceding vehicle.
Driving with DISTRONIC PLUS This section describes a number of driving
situations where special precaution is
required on the part of the driver. Be prepared
to brake in such situations. Braking will
deactivate the DISTRONIC PLUS system.
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. Driving systems

Parking instructions:
R
On narrow streets, drive by the parking
space as close as possible.
R Parking spaces that are dirty, overgrown or
located in front of trailers may not be
detected correctly.
R Snowfall or heavy rain may cause imprecise
measurement of the parking space.
R Also observe the Park Assist warning
indicator ( Y page 326) while the Advanced
Parking Guidance is active.
R How well your vehicle will be parked after
completion of the Advanced Parking
Guidance depends on the position and
shape of the vehicles parked in front of and
behind the parking space as well as the
conditions of the immediate surroundings.
In certain cases, the Advanced Parking
Guidance may guide you too far into the
parking space or not far enough. If this is
the case, cancel the parking procedure
with the Advanced Parking Guidance and
correct the vehicle position yourself.
Detecting a parking space The Advanced Parking Guidance is active
when driving forward. The system operates at
a vehicle speed of up to 25 mph (40 km/h).
It scans automatically for and measures
potential parking spaces on both sides of the
vehicle. :
Detected parking space on the left
; Parking space symbol
= Detected parking space on the right
At a vehicle speed of below 10 mph
(16 km/h), you see white parking space
symbol ; as a system display in the
multifunction display. As soon as the
Advanced Parking Guidance has detected a
suitable parking space, parking space
symbol ; changes to blue.
When a parking space has been detected, an
additional arrow to the right = or to the
left : appears.
In order to be detected by the Advanced
Parking Guidance, a parking space must be
R closed-in at the rear
R parallel to the direction of travel
R at least 5 ft (1.5 m) wide
R at least 3.5 ft (1.0 m) longer than your
vehicle is
A parking space is shown in the multifunction
display when driving by until you have
reached a distance of 50 ft (15 m) from the
space. The Advanced Parking Guidance only
shows parking spaces on the passenger side
of the vehicle unless you activate the driver’s
side (left) turn signal. If you would like to park
on the driver’s side, the left turn signal must
remain on until the reverse gear is engaged. Driving systems

and the safety of others, stop before trying to
remove window fogging or cleaning the
windshield in front of the Night View Assist
camera.
Bear in mind that at a speed of just 30 mph

necessary ( Y page 338).
X Swing the camera cover downward

X Cleaning inside of windshield: Use a soft,

The Blind Spot Assist uses radar sensors to
monitor the area on both sides of your
vehicle. It will assist you when you change
lanes driving at speeds of above 20 mph
(30 km/h). A red warning lamp will come on
in the exterior rear view mirror as soon as
another vehicle is detected. If you then
activate the corresponding turn signals to
change lanes, the red warning lamp flashes
and warning sounds (collision warning). The
Blind Spot Assist operates using two sensors
in the front bumper and four sensors in the
rear bumper. Driving systems

monitored area at these speeds.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic
conditions and to provide the steering,
braking and other driving inputs necessary to
retain control of the vehicle. Failure to do so
could result in recognizing dangers too late,
possibly resulting in an accident and serious
injury to yourself and others. Collision warning If a vehicle is detected in the Blind Spot Assist

Make sure the automatic transmission
remains in neutral position N. Observe
instructions, see “Remaining in neutral
position N” (Y page 292).
When leaving the automatic car wash, make

Ornamental moldings X
For regular cleaning and care of ornamental
moldings, use a damp cloth.
! Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings
may have chrome appearance, they could
be made of anodized aluminum that will be
damaged when cleaned with chrome
cleaner. Instead, use a damp cloth to clean
those ornamental moldings.
For very dirty ornamental moldings of
which you are sure are chrome-plated, use
a chrome cleaner. If in doubt whether an
ornamental molding is chrome-plated,
