MERCEDES-BENZ C-Class COUPE 2017 CL205 Owner's Manual

For safety reasons, Mercedes-Benz recom-
mends only installing the following brake disks
and brake pads/linings:
Rbrake disks that havebeena pproved by
Mercedes-Benz
Rbrake pads/lining sthat hav ebeena pproved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake disks or brake pads/lining scan
compromise the safety of your vehicle.
Alway sreplace al lbrake disks and brake pads/
linings on an axl eatthe sam etime. Always
install new brake pads/lining swhenr eplacing
brake disks.
The vehicle is equipped with lightweight brake
disks to which the wheel assembly with rim and
threaded connectio nismatched.
The use of brake disks other than those
approved by Mercedes-Benz can chang ethe
track width and is subject to approval ,ifappli-
cable.
Shock-typ eloads whe nhandling the brake
discs, such as whe nchanging wheels ,can lead
to areduction in comfortw hend riving with light-
weigh tbrake discs. Avoid shock-type loads on
the lightweight brake disks, particularly on the
brake plate.
Mercedes-Benz recommends that yo uonly use
brake fluid that has bee nspeciall yapproved for
your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard .Brake
fluid which has not bee napproved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
High-performance and ceramic brakes
(Mercedes AMG vehicles)
The AMG brake systems are designe dfor heavy
loads. Thism ay leadtonoisew henb raking. This
will depend on:
RSpeed
RBraking force
REnvironmental conditions, such as tempera-
ture and humidity
The wear of individua lcomponents of the brake
system, such as the brake pads/lining sorbrake
discs, depends on the individua ldriving style
and operating conditions.
For this reason, it is impossible to state amile-
ag ethat will be valid under al lcircumstances. An aggressive driving styl
ewilll ea dtoh ighw ear.
You can obtain more information on this from a
qualified specialist workshop.
New and replaced brake pads and discs only
reach thei roptimum braking effect afte rseveral
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
Kee pthis in mind ,and adap tyou rd riving and
braking accordingly during this break-in period.
Excessive heavy braking results in correspond-
ingl yhighb rake wear. Observe the brake wear
warning lamp in the instrument cluster and note
any brake statu smessages in the multifunction
display. Especiall yfor hig hperformance driving,
it is important to maintain and hav ethe brake
system checked regularly.

Hydroplaning
If water has accumulated to acertain depth on
the roads urface,there is adanger of hydro-
planing occurring, even if:
Ryo ud rive at low speeds.
Rthe tires hav eadequate treadd epth.
For this reason, in the event of heavy rai norin
conditions in which hydroplaning may occur,
yo um ustd rive in the following manner:
Rlower your speed.
Ravoid ruts.
Ravoid sudden steering movements.
Rbrake carefully.

Winter driving
GWARNING
If you shift downonaslipperyr oad surface in
an attempt to increas ethe engine' sbraking
effect, the drive wheels coul dlose their grip.
There is an increased dange rofskidding and
accidents.
Do not shift downf or additionalengine brak-
ing on aslipperyr oad surface.
GDANGER
If the exhaust pip eisblocked or adequate
ventilation is not possible ,poisonousg ases
such as carbo nmonoxide (CO )may enter the
vehicle. This is the case, e.g. if the vehicle
becomest rappedinsnow. There is arisk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pip eand area
around the vehicl eare clearofs now. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicl ethat is not
facing into the wind.
Have you rvehicl ewinter-proofed at aqualified
specialist worksho patthe onset of winter.
Drive particularly carefully on slipperyr oad sur-
faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use the cruis econ-
trol or DISTRONIC PLUS.
If the vehicl ethreatens to skid or cannot be
stoppedw hen moving at low speed:
XShift the transmission to position N.
The outside temperature indicator is not
designed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after ashort delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded area soronbridges. The vehicl ecould
skid if you fail to adapt you rdriving style .Always
adapt you rdriving style and drive at aspeedt o
sui tthe prevailing weather conditions.
You should pay special attention to road condi-
tions when temperatures are around freezing
point. For more information on driving with snow
chains, see (
Ypag
e319).
For more information on driving with summer
tires, see (

Cruise control
General notes
Cruise control maintains aconstant road speed
for you .Itbrakes automatically in order to avoid
exceeding the set speed. Change into alower
gearing ood time on long and steep downhill
gradients. This is especially important if the
vehicl eisladen. By doing so, you wil lmake use
of the braking effect of the engine. This relieves
the loa donthe brake syste mand prevents the
brakes from overheating and wearing too
quickly.
Use cruis econtrol only if road and traffic con-
ditions make it appropriate to maintain asteady
speedf orap rolonged period. You can store any
road speeda bove 20 mph (30 km/h).
Important safety notes
If you fail to adapt you rdriving style ,cruis econ-
trol can neither reduce the risk of an accident
nor override the law sofphysics. Cruise control
cannot take into account the road ,traffic and
weather conditions. Cruise control is only an
aid .You are responsiblef or the distance to the

Do not use cruise control:
Rin road and traffic conditions which do not
allow you to maintai naconstant speed, e.g. in
heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could caus ethe drive wheels to lose
traction and the vehicl ecould then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is achange of drivers ,advise the new
driver of the speeds tored.

164Driving systems
Driving and parking

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 yourvehicle.I n
this way ,the distance you have selected is main-
tained.
If DISTRONIC PLUS detects afaster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up to
the speed you have stored.
Selecting the drive program
DISTRONIC PLUS supports asporty driving style
when you have selected the Sor S+ driving pro-
gram (
Ypage 144). Acceleration behind the
vehicle in front or to the set speed is then notice-
abl ym ore dynamic. If you have selected the Cor
E driving 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:
Ryou are driving faster than 45 mph (70 km/h)
Ryou switch on the appropriate turn signal
RDISTRONIC PLUS does not detect adanger of
collision
If these conditions are fulfilled,y ourv ehicle is
accelerated. Acceleration wil lbeinterrupted if
changing lanes takes too long or if the distance
betwee nyourv ehicle and the vehicle in front
becomes too small.
iWhen you change lanes, DISTRONIC PLUS
monitors the left lane on left-hand-drive vehi-
cles or the right lane on right-hand-drive vehi-
cles.
Stopping
GWARNING
When leaving the vehicle,e ven if it is braked
only by DISTRONIC PLUS, it could roll awa yif:
Rthere is amalfunction in the system or in
the voltage supply.
RDISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by avehi-
cle occupant or from outsid ethe vehicle.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected.
Rthe accelerator pedalh as been depressed,
e.g. by avehicle occupant.
There is arisk of an accident.
If you wish to exit the vehicle,a lways turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
For further information on deactivating
DISTRONIC PLUS (
Ypage 167).
If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes you rvehicle until it is
stationary.
Once you rvehicle is stationary,itr emains sta-
tionary and you do not need to depresst he
brake.
iAfter atime, the electric parking brake
secures the vehicle and relieves the service
brake.
iDepending on the specifiedm inimum dis-
tance, you rvehicle wil lcome to astandstill at
as ufficient distance behind the vehicle in
front. The specifiedm inimum distance is set
using the control on the cruise control lever.
When DISTRONIC PLUS is activated, the trans-
missioniss hifted automatically to position Pif:
Rthe driver's seat belt is not fastened and the
driver's door is open.
Rthe engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function.
The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and:
Ras ystem malfunction occurs.
