ESP inoperative MERCEDES-BENZ CLS-Class 2014 W218 Owner's Manual

R
No modifications of any kind may be made
to any components or wiring of the SRS.
R Do not change or remove any component
or part of the SRS.
R Do not install additional trim material ,seat
covers, badges, etc. to the:
- padded steering wheel boss
- knee bag covers
- front-passenger air bag cover
- outer side of front seat bolsters
- side trim next to the rear seat backrest
- roof lining trim
R Do not install additional electrical/
electronic equipment on or near SRS
components and wiring.
R Keep area between air bags and occupants
free of objects (e.g. packages, purses,
umbrellas, etc.).
R Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may be thrown around in
the vehicle and cause head and other
injuries when the window curtain air bag is
deployed.
R Air bag system components willbeh ot after
an air bag has inflated. Do not touch them.
R Never place yourf eet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R Improper repairw ork on the SRS creates a
risk of rendering the SRS inoperative or
causing unintended air bag deployment.
Work on the SRS must therefor eonly be
performed by qualified technicians.
Contact an authorized Mercedes-Benz
Center.
R For your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These instructions are available from any authorized Mercedes-Benz
Center.
R Given the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, Mercedes-Benz
strongly recommends that you inform the
subsequent owner that the vehicle is
equipped with SRS. Also, refer them to the
applicabl esection in the Operator's Manual. Air bags
Important safety notes G
WARNING
If you modify the air bag covers or affix objects
such as stickers to them, the air bags may not
function correctly. There is an increased risk
of injury.
Never modify the air bag covers or affix
object stothem. G
WARNING
Using unsuitable seat covers could restric tor
even preven tdeployment of the air bags
integrated into the seats. Consequently, the
air bags cannot protec tvehicle occupant sas
they are designed to do. In addition, the
function of the air bag deactivation system
could be restricted. This poses an increased
risk of injury or even fatal injury.
You should only use seat cover sthat have
been approved for the respective seat by
Mercedes-Benz. G
WARNING
The air bag parts are hot after the airbag has
been deployed. There is arisk of injury.
Do not touch the air bag parts. Have the
deployed air bags replaced at aqualified
specialist workshop as soon as possible. 42

Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
(Y page 66)
R BAS ( Brake Assist System) (Y page 67)
R BAS PLUS ( BrakeAssist System Plus)
(Y page 67)
R ESP ®
(Electronic StabilityProgram)
(Y page 68)
R EBD ( Electronic Brake force Distribution)
(Y page 71)
R ADAPTIVE BRAKE (Y page 72)
R PRE-SAFE ®
Brake (Y page 72) Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are responsible for the distance to the vehicle in
front,f
or vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road, weather and traffic
conditionsa nd maintain asafe distanc efrom
th ev ehicle in front. Drive carefully.
i The driving safety systems describe donly
work as effectivel yaspossible when there
is adequat econtac tbetween th etires and
th er oad surface. Pleas epay special
attentio ntothenote sont ires,
recommende dminimu mtire tread depths,
etc .(Ypage 334).
In wintry drivin gconditions, always use
winter tires (M+S tires) and if necessary,
sno wchains. Only in this way will the
drivin gsafet ysystems described in this
section work as effectively as possible. ABS (Anti-lock Brakin
gSystem)
Important safety notes i
Observe the "Importan tsafet ynotes"
sectio n(Ypage 66). G
WARNING
If ABSisf aulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
Drive on carefully.H ave ABS checked
immediately at aqualified specialist
workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 267) and
displaym essages which may be shown in the
instrument cluster (Y page 238).
ABS regulates brake pressure in such away
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking. 66

Warning and display messages in the
multifunction display X
Activate ATTENTION ASSIST using the on-
board computer (Y page228).
If ATTENTION ASSIST is active, you wil lbe
warned no sooner than 20 minutes after
you rjourney has begun. You then hear an
intermittent warning tonet wice and the
Attention Assist :Drowsiness detected message appears in the
multifunction display.
X If necessary, tak eabreak.
X Pres sthe 000C button to confir mthe

On lon gjou rneys, tak eregular break singood
tim etoa llow yourself to rest properly. If you
do not tak eabreak,you will be warned again
after 15 minutes at th eearliest. The
preconditio nfor this is that
ATTENTION ASSIST still detect stypical
indicators of fatigue or increasing lapses in
concentration.
When ATTENTION ASSIST is deactivated, the
0001 symbol and OFF appear in the
multifunction display in the assistance
graphics display when the engine is running.
ATTENTION ASSIST is reset when you
continue your journey and startsa ssessing
your tiredness again if:
R you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for achange of drivers or
to take abreak. Night View Assist Plus
Important safety notes Night View Assist Plus is only an aid and is not
as ubstitute for attentive driving. Do not rely
on the Night View Assist Plus display .You are
responsible for the distance to the vehicle in
front,f or vehicle speed and for braking in
good time. Drive carefully and always adapt your driving style to suit the prevailing road
and traffic conditions.
The system may be impaired or may not
function if:
R
there is poor visibility, e.g. due to snow,
rain, fog or spray
R the windshield is dirty, fogged up or
covered, for instance by asticker, in the
vicinit yofthe camera
R on bends, on uphill gradients or downhill
gradients
Pedestrian recognition may be impaired or
inoperative if:
R pedestrians are partially or entirely
obscured by objects, e.g. parked vehicles
R the silhouette of the pedestrian in the Night
View Assist Plus display is incomplet eor
interrupted, e.g. by powerful light
reflections
R pedestrians do not contrast adequately
from the background
R pedestrians are not in an upright position,
e.g. sitting, squatting or lying In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road.
Night View Assist Plus camera
001Apicks up
the infrared light and display samonochrome
image in COMAND. The image displayed in
COMAND corresponds to aroad lit up by high-
beam headlamps. This enables you to see the
road's course and any obstacles in good time.
If pedestrian recognition is activated,
pedestrians recognized by the system are 204
