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

The ECO display consistsofthree sections, with
an inner and outer area. The section scorre-
spond to the following three categories:
:Acceleration (evaluation of all accel-
eration processes):
Rthe outer area fills up and the inner area lights up green: moderate
acceleration ,especially at higher
speeds
Rthe outer area empties and the
inner area is gray: sporty acceler-
ation
;Coasting (evaluation of all decelera-
tion processes):
Rthe outer area fills up and the inner area lights up green: anticipatory
driving, keeping your distance and
early release of the accelerator.
The vehicle can coast without use
of the brakes.
Rthe outer area empties and the
inner area is gray: frequent heavy
braking
=Constant (continuous evaluation
over the entir ejourney):
Rthe outer area fills up and the inner
area lights up green: constant
speed and avoidance of unneces-
sary acceleration and deceleration
Rthe outer area empties and the
inner area is gray: fluctuations in
speed
The three inner areas display the current driving
style and light up green as aresult of aparticu-
larly economical driving style. Dependin gonthe
driving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as aresult of eco-
nomical driving. Ahigher level indicates amore
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved range
displayed under Bonus fr. Start
does not
indicate afixed consumption reduction. In addition to driving style, the actual consump-
tion is affected by other factors, such as:
Rload
Rtire pressure
Rcold start
Rchoice of route
Relectrical consumer
sswitched on
These factor sare not included in the ECO dis-
play.
An economical driving style specially requires
driving at moderate engine speeds.
Achievingah igher value in the categories
"Acceleration" and "Constant":
Robserve the gearshift recommendations.
Rdrive in drive program E.
On long journeys at aconstant speed, e.g. on the
highway, only the outer area for "constant" will
change.
The ECO display summarizes the driving style
from the start of the journey to its completion.
Therefore, there are more marked changes in
the outer areas at the start of ajourney. On lon-
ger journeys, there are fewer changes. For more
marked changes, perform amanual rest
(
Ypage 206).

Braking
Important safety notes
GWARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect,t he drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on aslippery road surface.
Downhill gradients
!On long and steep gradients, you must
reduce the load on the brakes by shiftin gtoa
lower gear in good time. This allows you to
take advantage of the engine's braking effect.
This helps you to avoid overheating the
brakes and wearing them out excessively.

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 (
Ypag e318).
Observe the notes i
n the "Winter operation" sec-
tion (Ypag e318).

Mercedes-Benz Intelligent Drive stands for inno-
vative drive rassistance and safety systems
which enhance comfort and support the drive rin
critical situations. With these intelligent co-ordi-
nated systems Mercedes-Benz has set amile-
stone on the path towards autonomous driving.
Mercedes-Benz Intelligent Drive embraces all
elements of active and passive safety in one well
though tout syste m–for the safety of the vehi-
cle occupants and that of other road users.

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

Coolant
Importan tsafety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is arisk of fire and injury.
Let the engine cool dow nbefore yo uadd anti-
freeze .Make sur ethat antifreeze is not spilled
next to the filler neck. Thoroughly clea nthe
antifreeze from components before starting
the engine.
!Only ad dcoolant that has bee npremixed
with the desire dantifreeze protection. You
coul dotherwise damag ethe engine.
Furthe rinformatio noncoolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact aqualifie dspecialist workshop.
!Always use asuitabl ecoolant mixture, even
in countries where hig htemperatures prevail.
Otherwise ,the engine cooling system is not
sufficiently protected from corrosion and
overheating.
iHave the coolant regularly replaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety notes for ser-
vice products whe nhandling coolant
(
Ypage 344).
The coolant is amixture of water and anti-
freeze/corrosion inhibitor. It performs the fol-
lowing tasks:
RAnti-corrosion protection
RAntifreeze protection
RRaising the boiling point
If the coolant has antifreeze protection dow nto
-35 ‡(-37† ), the boiling point of the coolant
during operation is approximatel y266 ‡
(130 †).
