ignition MERCEDES-BENZ S CLASS 2016 Manual PDF

Either no braking application, or a course-cor-
recting brake application adapted to the driving
situation occurs if: R
there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your vehicle. R
a vehicle approaches you too closely at the
side. R
you have adopted a sporty driving style with
high cornering speeds. R
you clearly brake or accelerate. R
a driving safety system intervenes, e.g. ESP ®
or PRE-SAFE ®
Brake.R
ESP ®
is switched off.R
a loss of tire pressure or a defective tire is
detected.
Switching on Active Blind Spot Assist X
Make sure that Active Blind Spot Assist is
activated in the on-board computer
( Y
page 271). X
Turn the SmartKey to position 2 in the ignition
lock.
Warning lamps C in the exterior mirrors light
up red for approximately 1.5 second s. Gray
radar waves propagating backwards appear
next to the vehicle in the assistance display in
the multifunction display.
Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunction
camera C at the top of the windshield. Various
different areas to the front, rear and side of your
vehicle are also monitored with the aid of the
radar sensor system. Active Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin- tentionally. If you do not react to the warning, a
lane-correcting application of the brakes can
bring the vehicle back into the original lane.
This function is available in a speed range
between 40 mph and 120 mph (60 km/h and
200 km/h).
Important safety notes If you fail to adapt your driving style, Active Lane
Keeping Assist can neither reduce the risk of
accident nor override the laws of physics. Active
Lane Keeping Assist cannot take account of
road and weather conditions. It may not recog-
nize traffic situations. Active Lane Keeping
Assist is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
your lane.
Active Lane Keeping Assist cannot continuously
keep your vehicle in its lane.
G WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can: R
give an unnecessary warning and then
make a course-correcting brake application
to the vehicle R
not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
The system may be impaired or may not function
if: R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray R
there is glare, e.g. from oncoming traffic, the
sun or reflections (e.g. when the road surface
is wet) R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the cameraDriving systems 237

road categories R
spee d limitation sR
dat a on downhill gradients The use of electric energ y is automatically opti-
mally distributed from th e beginnin g to th e en d

route. The distribution is pre-emptive and takes
int o consideration : R
th e sections of th e journey aheadR
th e energ y consumption on th e whole rout e
The condition of charge of th e high-voltage bat -
tery is thus systematically controlled. In addi-
tion, th e control function takes int o accoun t
that: R
th e fuel saving s throug h th e use of electrical
energ y can vary, depending on th e rout e (e.g.
urban , interurban or highway) R
th e use of electrical energ y is held available in
particular for electric operation (e.g. urban

The vehicl e thus automatically select s th e opti-

Off Before Exiting PLUG-IN HYBRID vehicles:
You are leaving the vehicle when it is in a ready-to-drive state. The
READY indicator in the multifunction display is on. A warning tone also
sounds.
If you leave the vehicle: X
Secure the vehicle against rolling away ( Y

Switch off the ignition and remove the SmartKey.
If you do not leave the vehicle: X
Switch off the electrical consumers, e.g. automatic climate control,
seat heating.
Please note the following: the electrical consumers are supplied by the
12 V battery. If the vehicle is left in a ready-to-drive state for an exten-
ded period, it will switch off once the 12 V battery is almost empty. It
will then only be possible to start the vehicle using a second battery
(jump-starting).
