becomes trapped in snow. There is
arisk of
fatal injury.
If you leave the engin eorthe auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not
facin gintot he wind.
At the onset of winter ,have your vehicle win-
terized at aqualified specialist workshop, e.g.
at an authorized Mercedes-Benz Center.
Driv eparticularly carefully on slippery road
surfaces. Avoid sudden acceleration, steering
and brakin gmaneuvers. Do not use cruise
control.
If the vehicle threatens to skid or cannot be
stopped when movin gatlow speed:
X Shift 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 freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges. You
should pay special attention to road condi-
tion swhen temperatures are around the
freezing point.
For more information on driving with snow
chains, see (Y page 253).
For more information on driving with summer tires, see (Y page 252).
Observe the notes in the "Winter operation"
section (Y page 252). Driving systems
Cruise control
Important safet ynotes Cruise contro
lmaintains aconstan troad
speed for you. It brakes automatically in order
to avoid exceeding the set speed.
On long and steep downhill gradients, espe-
cially if the vehicle is laden, you must select
shift range 1,2or 3in good time
(Y page 127). By doing so, you will make use
of the brakin geffec toft he engine. This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
If you fail to adapt your driving style, cruise
contro lcan neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
contro lcannot take int oaccoun tthe road,
traffic and weather conditions. Cruise control
is only an aid. You are responsible for the dis-
tanc etot he vehicle in front, for vehicle speed,
for brakin gingood time and for staying in
your lane.
Use cruise contro lonly if road and traffic con-
dition smake it appropriate to maintain a
steady speed for aprolonge dperiod. You can
set any road speed above 20 mph (30 km/h).
Do not use cruise control:
R in road and traffic condition swhich do not
allow you to maintain aconstan tspeed e.g.
in heavy traffic or on winding roads
R on slippery road surfaces. Braking or accel-
eratin gcould cause the drive wheels to lose
traction and the vehicle could then skid
R when ther eispoor visibility, e.g. due to fog,
heavy rain or snow
If ther eisac hangeofd rivers, advise the new
driver of the speed stored. 138

sary service work has been carried out. You
can also obtain further information on main-
tenancew ork, for example.
! If the service interval displayh
as been
reset unintentionally,h ave the setting cor-
rected at aMercedes-Benz Center.
Have service work carried out as described in the Maintenance Booklet. This may oth-
erwise lead to increased wear and damage
to the major assemblies or the vehicle.
Special service requirements
The specified maintenance interval takes only the normal operation of the vehicle into
account. Under arduouso perating conditions
or increased load on the vehicle, mainte-
nance work must be carried out more fre-
quently, for example:
R regularc ity driving with frequent intermedi-
ate stops
R if the vehicle is primarily used to travel
short distances
R use in mountainous terrain or on poor road
surfaces
R if the engine is often left idling for long peri-
ods
Under these or similarc onditions, have, for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduouso perating conditions, the tires must
be checked more often. Further information
can be obtained at aqualified specialist work-
shop, e.g. an authorized Mercedes-Benz
Center.
Driving abroad
An extensive Mercedes-Benz Service network is also available in other countries. You can
obtain further information from any author-
ized Mercedes-Benz Center. Care
General notes
Regular care of your vehicle is acondition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. aring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film. H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
! Do not park the vehicle for an extended
period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for afew minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked. Exterior care
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. There is arisk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored. Care
223Maintenance and care Z

You can wash the vehicle in an automatic car
wash fro mthe very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Never clean your vehicle in
aTouchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agent scan
damage the paintwork or plastic parts.
! When washing your vehicle in
atow-
through car wash, use the SmartKey
instead of the Start/Stop button.
Start the engin eusing the SmartKey.. Move
the transmission to Nwith the E-SELECT
lever .Use the SmartKey to switc hthe
engin eoff again and the nturn the Smart-
Key to position 2.Make sure that you then
leave the SmartKey in position 2.You may
otherwise damage the vehicle, the trans-
missio northe car wash.
Check the transmission position in the
instrumen tcluster.
! Use the E‑SELECT lever to shift the trans-
missio ntoNbefore switching the engine
off .Ify ou open the driver's or front-
passenger door, the transmission remains
in this position for up to 30 minutes if the
SmartKey is in the ignition, even if the
engin eisswitched off .Ifyou do not shift the
transmission to Nusing the E‑SELECT lever
beforehand, it shift sautomatically to park-
ing position Pand lock sthe wheels if the
driver's or front-passenge rdoor is opened
and the engin eisswitched off .This may
damage the vehicle, the transmission or
the car wash.
Observe the information on maneuvering
(Y page 131). !
Before drivin
gintoana utomatic car wash,
make sure that it is suitable for the dimen- sion soft he vehicle. In particular, make
sure that:
R there is enough groun dclearance
betwee nthe vehicle underbody and the
guide rails of the automatic car wash.
R the clearance width of the automatic car
wash is sufficient ,particularly the width
of the guide rails.
R you enter the automatic car wash
straight and in the center of the guide
rails in order to avoid damagin gthe tires
or wheel rims.
Fold in the exterior mirrors befor ethe vehi-
cle is washed. The exterior mirrors could
otherwise be damaged.
! Make sure that:
R the side windows and the roof are com-
pletely closed
R the climat econtrol blower is switched off
R the windshield wiper switc hisatposition
0
The vehicle could otherwise be damaged.
! In portal car washes, the windshield wip-
ers may be move dupthe windshield by the
cleaning brushes when the ignition is
switched off.
Set the Start/Stop button to key position 2
to reset the windshield wipers to their orig-
inal position.
! Preferably use automatic car washes with
adjustable high-pressure pre-cleaning. This corresponds with the specification for the
Cabriolet program. In car washes that use
high water pressures, there is arisk that a
small amount of water may leak int othe
vehicle.
! Cabriolet:
do not treat the vehicle with
hot wax under any circumstances.
After using an automatic car wash, wipe off
wax and drying agent sfromt he windshield
and the wiper blades. This will prevent smears 224
