2016 MERCEDES-BENZ CLA service

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
front has slowed down, it brakes your vehicle.
In this way, the distance you have selected is
maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
The vehicle is only accelerated up to the
speed you have stored.
Selecting the drive program
DISTRONIC Plus supports a sporty driving
style when you select the S+ (Mercedes-AMG
vehicles only) or S ( Y
page 162) drive program
or the manual gearshift ( Y
page 164). Accel-
eration behind the vehicle in front or to the set
speed is then noticeably more dynamic. If you
have selected the E (Mercedes-AMG vehicles:
C ) drive program, the vehicle accelerates
more gently. This setting is recommended in
stop-and-start traffic.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when: R
you are driving faster than 43 mph
(70 km/h) R
DISTRONIC PLUS is maintaining the dis-
tance 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 dis-
tance between your vehicle and the vehicle in
front becomes too small. Stopping
G WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if: R
there is a malfunction in the system or in
the voltage supply. R
DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle. R
the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with. R
the battery is disconnected. R
the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
For further information on deactivating
DISTRONIC PLUS ( Y
page 185).
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 After a time, the electric parking brake
secures the vehicle and relieves the service
brake.
i Depending on the specified minimum dis-
tance, 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. Driving systems 183

If necessary, take a break. X
Confirm the message by pressing the v
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break and ATTENTION ASSIST
still detects increasing lapses in concentra-
tion, you will be warned again after
15 minutes at the earliest. This will only hap-
pen if ATTENTION ASSIST still detects typical
indicators of fatigue or increasing lapses in
concentration.
If a warning is output in the multifunction dis-
play, a service station search is performed in
COMAND. You can select a service station
and navigation to this service station will then
begin. This function can be activated and
deactivated in COMAND.
Lane Tracking package
General notes
The Lane Tracking package consists of Blind
Spot Assist ( Y
page 205) and Lane Keeping
Assist ( Y
page 207).
Blind Spot Assist
General notes
Blind Spot Assist monitors the areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facing radar sen-
sors. A warning display in the 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 warn-
ing.
Blind Spot Assist supports you from a speed
of approximately 20 mph (30 km/h). Important safety notes
G WARNING
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 a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.

Emergency call Important safety notes
G WARNING
It can be dangerous to remain in the vehicle,
even if you have pressed the SOS button in an
emergency if: R
you see smoke inside or outside of the vehi-
cle, e.g. if there is a fire after an accident R
the vehicle is on a dangerous section of
road R

cle occupants. In such situations, secure the
vehicle in accordance with national regula-
tions, e. g. with a warning triangle.
General notes
Observe the notes on system activation
( Y
page 282).
An emergency call is dialed automatically if an
air bag or Emergency Tensioning Device is
triggered. You cannot end an automatically
triggered emergency call yourself.
An emergency call can also be initiated man-
ually.
As soon as the emergency call has been ini-
tiated, the indicator lamp in the SOS button
flashes. The Connecting Call
message
appears in the multifunction display.

tiated, a voice connection is automatically
established between the Customer Assis-
tance Center and the vehicle occupants. R
If the vehicle occupants respond, the
Mercedes-Benz Customer Assistance Cen-
ter attempts to get more information on the
emergency. R
If there is no response from the vehicle
occupants, an ambulance is immediately
sent to the vehicle.
If no voice connection can be established to
the Mercedes-Benz Customer Assistance
Center, the system has been unable to initiate
an emergency call.

mobile phone network is not available. The
indicator lamp in the SOS button flashes con-
tinuously.
The Call Failed message appears in the
multifunction display and must be confirmed.
In this case, summon assistance by other
means.
