Otherwise, you may fail to recognise dangers
in time, cause an accident and injure yourself
and others. G
WARNING
DISTRONIC PLUS brakes your vehicle up to a
maximum of 4 m/s 2
depending on its speed.
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must also apply the brakes yourselfift his
braking power is not sufficient.
If DISTRONIC PLUS detects a risk of collision
with avehicle in front, an intermittent warning
tone sounds. In addition, the ·distance
warning lamp in the instrument cluster lights
up. Brake to avoid a collision.
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tance to the vehicle detected in front. DIS-
TRONIC PLUS brakes automatically so that
the set speed is not exceeded.
On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer
(CLS Shooting Brake only), you must select
shift range
1,2or 3in good time. By doing
so, you will make use of the braking effec tof
the engine .This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
If DISTRONIC PLUS detects a slower-moving
vehicle in front, your vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
(Y page 243) and operational.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities (Y page 398).
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between
30 km/h and 200 km/h. If avehicle is driving in front of you, DISTRONIC operates in the
speed range between 0km/h and
200 km/h.
Do not use DISTRONIC PLUS on roads with
steep gradients.

Activating DISTRONIC PLUS
Important safety notes
G
WARNING
The vehicle can be braked when DISTRONIC
PLU Sis activated. For this reason, deactivate
DISTRONIC PLUS if the vehicle is to be set in
motion by other means (e.g. in a car wash or
by towing).
Activation conditions
To activate DISTRONIC PLUS, the following
conditions must be fulfilled:
R the engine must be running. It may take up
to two minutes of driving before DIS-
TRONIC PLUS is ready for use.
R the parking brake must be released.
R ESP ®
must be switched on, but not inter-
vening.
R the transmission must be in position D.
R the bonnet must be closed.
R the driver's door must be closed when you
shift from Pto Dor your seat belt must be
fastened.
R the front-passenger door and the rear
doors must be closed.
R the vehicle must not be skidding.
Activating while driving X
Briefly pull the cruise control lever towards
you ;, or press it up :or down =.
DISTRONIC PLUS is selected.
X Keep the cruise control lever pressed
up : or down =until the desired speed
is set.
X Remove your foot from the accelerator
pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
When driving at speeds below 30 km/h, you
can only activate DISTRONIC PLUS if the vehi-
cle in front has been detected and is shown
in the multifunction display. If the vehicle in
front is no longer detected and displayed,
DISTRONIC PLUS switches off and you will
hear a tone.
i If you do not fully release the accelerator
pedal, the DISTRONIC PLUS suspended message appears in the multifunction dis-
play.T he set distance to a slower moving
vehicle in front will then not be maintained.
You will be driving at the speed you deter-
mine by the position of the accelerator
pedal.
Activating when driving towards asta-
tionary vehicle
X Briefly pull the cruise control lever towards
you ;, or press it up :or down =.
DISTRONIC PLU Sis selected.
X Press the cruise control lever repeatedly
up : or down =until the desired speed
is set.
If the vehicle in front of you is stationary, you
can only activate DISTRONIC PLUS once your
vehicle is stationary as well.
i DISTRONIC PLUS can only be activated at
under 30 km/h if a vehicle in front has been
detected. Therefore, the DISTRONIC PLUS
distance display in the instrument cluster
should be activated (Y page 237). Driving systems

Detecting parking spaces
Example: detected parking space
:
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Active Parking Assis tisswitched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of th evehicle. When
driving at speeds below 30 km/h, you will see
the parking symbol as a status indicator in the
instrumen tcluster .Active Parking Assist only
displays parking spaces on the front-
passenger side as standard .Parking spaces
on the driver's side are displayed as soon as
the tur nsignal on the driver's side is activa-
ted. To park on the driver's side, you must
leave the driver's side tur nsignal switched
on. This must remain switched on until you
acknowledge the use of Active Parking Assist
by pressing the abutton on the multi-
function 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 1.5 m wide
R that are at least 1.3 m longer than your
vehicle
Ap arking space is displayed while you are
driving past it, and until you are approx-
imately 15 m away from it. Parking G
WARNING
PARKTRONIC and Active Parking Assist are
merely parking aids and may no tdetec tall
obstacles. They do not relieve you of the
responsibility of paying attention.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could, otherwise, endanger
yourself and others. G

must steer again yourself.
Towing atrailer For vehicles with a trailer tow hitch, the min-
imum length for parking spaces is slightly
increased.
If you have attached a trailer to your vehicle,
you should not use Active Parking Assist.

WARNING
Only use the on-board computer when road
and traffic conditions permit .You would oth-
erwise be distracted and unable to concen-
trate properly on driving, and could cause an
accident. G
WARNING
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such as
speed, outside temperature, warning and indi-
cator lamps, display messages or system fail-
ures. Driving characteristics may be impaired.
Adjust your driving style and vehicle speed
accordingly.
Contact a qualified specialist workshop
immediately. G
WARNING
The on-board computer only records and dis-
plays malfunctions and warnings from certain
systems. For this reason, you should always
make sure that your vehicle is safe to use. You
could otherwise cause an accident by driving
an unsafe vehicle. G
WARNING
The operating safety of your vehicle could be
impaired if maintenance work is carried out
incorrectly. This could cause you to lose con-
trol of your vehicle and cause an accident.
Moreover, the safety systems may no longer
be able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop.
