2010 MERCEDES-BENZ E-CLASS CABRIOLET brake

Heav
yand light loads G
Risk of accident
Never depr esst he brake pedal continuously
while the vehicle is in motion ,e.g. never cause
the brakes to rub by applying cons tant slight
pedal pressure. Thi scauses the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
If the brakes have been subjected to aheavy
load, do not stop the vehicle immediately ,but
drive on for ashort while. This allow sthe air-
flo wtoc ool the brakes mor equickly.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet roads If driving in heavy rain for
aprolonged period
of time without braking, there may be a
delayed reaction from th ebrake swhen brak-
ing for the first time. This ma yalso occur after
the vehicle has been washed.
You have to depress the brake pedal more
firmly. Maintain agreater distance from the
vehicl einfront.
After driving on awet road or havin gthe vehi-
cle washed, brake firml ywhile paying atten-
tion to the traffic conditions. This will warm
up the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking perfo rmance on salt
treated roads G
Risk of accident
The layer of salt on the brake discs and the
brake pads/linings may cause adelay in the
braking effect ,resultin ginas ignifican tlyl on-
ger brakin gdistance, which could lead to an
accident.
To avoid this danger, you should: R
occasionally brake carefully, without put-
ting other road users at risk, when you are
drivin gons alted roads. This helps to
remove any salt that may have started to
build up on the brake discs and the brake
pads/linings.
R maintain agreater distance to th evehicle
ahead and driv ewith particular care.
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake discs.
New brake pads/linin gs G
Risk of accident
New brake pads/lining sonly reach thei ropti-
mum braking effect after severa lhundred kil-
ometres of driving. Before this optimum brak-
ing effect is reached, you should compensate
for the reduced braking effect by applying
greater pressure when braking. This also
applies after the brake discs or the brake
pads/lining shave been replaced.
For safety reasons, Mercedes-Benz recom-
mends that you only have brake pads/linings
fitted to your vehicle which have been
approved for Mercedes-Benz vehicles or
which correspond to an equivalent quality
standard. Brake pads/lining swhich hav enot
been approved for Mercedes-Benz vehicles or
which ar enot of an equivalent quality could
affect your vehicle' soperating safety. Ty
re traction G
Risk of accident
Whil ethe vehicle can be fully con trolled at a
cer tain speed on dry roads, you must reduce
your speed on wet or icy roads to achieve the
same road safety. Otherwise, you could cause
an accident.
Pay particular attention to the road conditions
at temperatures around freezin gpoint. Driving tips

Aquapla ning If water has accumulated to

on th eroad surface, there is adanger of aqua-
planing occurring, even if:
R you driv eatlow speeds
R thet yres have adequat etread depth
For this reason ,donot drive in tyre ruts ,and

Driving on flooded roads If you have to driv

R the maximu mpermitted dept hins till water

R you should driv enofaster than at walking

Failure to observe these notes may result

Important safety notes Have your vehicle winterproofed at

Servic eCentre, at the onset of winter.

thes etyres have been designed specifically
for driving on snow.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
Winter tyres with atrea ddepth of less than
4mmm ust be replace dimmediately. They are
no longe rsuitable for winter use and can no
longer provid esufficient grip. This could
cause you to lose control of you rvehicle and
cause an accident.
Alway sobserv ethe maximum permissible
speed specifie dfor the winter tyres you have
fit ted. If you fit winter tyres which have a
lower maximum permissible speed than that
of the vehicle, affix an appropriate warning
sign in the driver' sfield of vision. This can be
obtained at aqualified specialist workshop,
e.g. from aMercedes-Benz Ser vice Centre.
Under these circumstances, you shoul dalso
restrict the maximum speed of the vehicle
using permanen tSPEED-

(Y page 17 1)so that it does not
exceed the maximum permissible speed for
the winter tyres.

Cruise control
Import ants afety notes Cruise control maintain
saconstant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhil lgradients ,especially if the
vehicle is laden or towing atrailer, yo umust
shift to alower gear in good tim eorselect
shift range 1,2or 3on vehicles with auto-
matic transmission. By doing so, you will
mak euse of the brakin geffect of th eengine,
which relieves the load on the brake system and prevents the brakes from overheating
and wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. Yo ucan
store any road spee dabove 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay atten tion to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for brakin gingood time. G
Risk of accident
Do not use cruise control:
R in road and traffic condition swhich do not
allow you to maintain aconstant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R on slippery roads. Brakin goraccelerating
coul dcause the drive wheels to lose trac-
tion and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
