2015 MERCEDES-BENZ C-CLASS COUPE brake

If yourv
ehicle/trailer combination begins to
lurch, you can only stabilise the vehicle/trailer
combination by depressing the brake firmly.
ESP ®
trailer stabilisatio nisactive above speeds
of approximately 65 km/h.
ESP ®
trailer stabilisatio ndoes not work if ESP ®
is deactivated or disabled because of amalfunc-
tion.
Crosswind Assist General notes
Strong crosswind gusts can impair the road-
holding of yourv ehicle when driving straight
ahead. The crosswind driving assistance func-
tion integrated in ESP ®
noticeably reduces
these impairments.
Depending on the direction and intensity of the
side wind, ESP ®
is activated automatically.
ESP ®
intervenes with stabilising braking to
assisty ou in keeping the vehicle in the lane.
Crosswind Assist is active at vehicle speeds
above 80 km/h when driving straight aheador
cornering gently.
Important safety notes Crosswind Assist does not work if ESP ®
is deac-
tivated or disabled because of amalfunction. EBD (electroni
cbrake force distribu-
tion)
General notes EBD monitors and controls the brake pressure
on the rear wheelstoi
mprove driving stability
whileb raking.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If EBD is malfunctioning, the rear wheelsc an
lock, e.g. under full braking. This increases the risk of skidding and an accident.
You shouldt herefore adapt yourd riving style
to the different handling characteristics. Have the brake system checked at
aqualifieds pe-
cialist workshop.
Observe information regarding indicator and
warning lamps( Ypage 287) as well as display
messages (Y page 256). ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety and
offers increased braking comfort. In addition to
the braking function, ADAPTIVE BRAKE also has
the HOLD function (Y page 192) and hill start
assist (Y page 149). PRE-SAFE

Brake
General notes PRE-SAFE
®
Brake can help you to minimise the
risk of acollision with avehicle aheadora
pedestrian, and reduce the effects of such a
collision. If PRE-SAFE ®
Brake has detected arisk
of ac ollision, you willbew arned visually and
acoustically as well as by automatic braking.
i Pay attention to the important safety notes
in the "Driving safety systems" section
(Y page 66).
PRE‑SAFE ®
Brake is only available in vehicles
with the Driving Assistance Plusp ackage.
For PRE-SAFE ®
Brake to assist you when driving,
the radars ensor system and the camera system
must be switched on and operational.
With the help of the radars ensor system and the
camera system, PRE-SAFE ®
Brake can detect
obstacle sthat are in front of yourv ehicle for an
extended period of time.
In addition, pedestrians in the path of yourv ehi-
cle can be detected.
PRE-SAFE ®
Brake detects pedestrians using
typica lcharacteristics such as the body con-
tours and posture of aperson standing upright.

tLight System
General notes The Intelligent Light System is
asystem that
adjusts the headlamps automatically to suit the
prevailing driving and weather conditions. It
offers advanced functions for improved illumi-
nation of the road surface, e.g. depending on the vehicle speed or weather conditions. The sys-
tem includes the active light function, cornering light function, motorway mode, extended range
foglamps and off-road lights. The system is only
active when it is dark.
You can activate or deactivate the "Intelligent
Light System" function using the on-board com- puter (Y page 247).
Active light function The active light function is
asystem that moves
the headlamps according to the steerin gmove-
mentsoft he front wheels. In this way, relevant
areas remain illuminated while you are driving.
This allows you to recognise pedestrians,
cyclists and animals.
Active: when the lights are switched on.
Cornering light function The cornering light function improves the illu-
mination of the road over
awide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. It can only be
activated when the dipped-beam headlamps are
switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the steer- ing wheel
R if you are driving at speeds between 40 km/h
and 70 km/ha nd turnthe steering wheel
The cornering light function may remain lit for a
shor ttime, but is automatically switched off
after no mor ethant hree minutes. Motorwa

if you are driving at aspee dabove
11 0k m/ hand do no tmakea ny large steering

Not active: if you are driving at speeds below
80 km/h followin gactivation.
Extended range foglamps The extended range foglamps reduc
ethe glare
experienced by th edriver and improve th eillu-
minatio noftheedge of th ecarriageway.
Active: if you are driving at speeds below
70 km/h and you switch on th erear foglamp.
Not active: if, followingactivation ,you are driv-
ing at speeds abov e100 km/h or if you switch
off th erear foglamp. Adaptive Highbeam Assist Plus
General notes Wit
hA daptiv eHighbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam headlamps.
Partial main-beam illuminatio nisaformofi llu-
minatio nwhereby th emain beam is directed
past other road users. Other road user sare kept
out of th emain-beam. This prevent sglare .If
there is avehicle in front, for example, th emain-
