i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please not ethat your vehicle may
not be equipped with all features
described. This also applies to safety-
related system sand functions.

following pages. The windows could
otherwise fog up.
To preven tthe windows from fogging up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air
dehumidification function
R switch on the defrost windshield function
briefly, if required
The automatic climate control regulates the
temperature and the humidity of the vehicle
interior and filters out undesirable
substances from the air.
Automatic climate control/dual-zone
automatic climate control is only operational
when the engine is running. Optimum
operation is only achieved with the side
windows and panorama roof with power tilt/
sliding panel closed.
The residual heat function can only be
activated or deactivated with the ignition
switched off (Y page 132).
i Ventilate the vehicle for abrief period
during warm weather, e.g. using the
convenience opening feature (Y page 84).This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
i The integrated filter filters out most
particles of dust and soot and completely
filters out pollen. With dual-zonea utomatic
climate control, gaseous pollutantsa nd
odors will also be reduced. Aclogged filter
reduces the amoun tofair supplied to the
vehicle interior .For this reason, you should
always observe the interval for replacing
the filter, which is specified in the
Maintenance Booklet .Asitdepends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
stated in the Maintenance Booklet.
i It is possible that the dehumidification
function of the climate control system may
be activated automaticallyanh our after the
SmartKey has been removed. The vehicle
is then ventilated for 30 minutes. 122

If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automaticallyinc ertain situations. To
prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similars ituations:
R when towin gthe vehicle
R in the car wash
If you fail to adapt your drivin gstyle,
DISTRONIC PLUS can neither reduc ethe risk
of accident nor override the laws of physics.
DISTRONIC PLUS cannot tak einto account
the road, traffic and weather conditions.
DISTRONI CPLUSiso nlyana id.Y ou are
responsibl efor the distance to the vehicl ein
front, for vehicl espeed ,for braking in good
time and for staying in your lane.
Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain aconstant speed e.g.
in heavy traffic or on winding roads
R on slippery road surfaces. Brakin gor
accelerating could cause the drive wheels
to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow
vehicles driving in front,e .g. motorcycles, or
vehicles driving on adifferent line.
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else
coverin gthe sensors
R snow or heavy rain
R interferenc ebyother radar sources
R strongr adar reflections, for example, in
parking garages
If DISTRONIC PLUS no longer detect sa
vehicle in front,D ISTRONIC PLUS may
unexpectedly accelerate the vehicle to the
stored speed. This speed may:
R
be too high if you are driving in afilter lane
or an exit lane
R be so high when driving in the right-hand
lane that you overtak evehicles in the left-
hand lane
R be so high when driving in the left-hand lane
that you overtak evehicles in the right-hand

Activating DISTRONIC PLUS Activation conditions
To activate DISTRONIC PLUS, all of the
following activation conditions must be
fulfilled:
R
the engine must be started. It may take up
to two minutes after pullinga way before
DISTRONIC PLUS is operational.
R the electric parking brake must be
released.
R ESP ®
must be active, but not intervening. 164

If the ASSYST PLUS service interval
displayh as been inadvertently reset, this
settingc an be corrected at aqualified
specialist workshop.
Have service work carried out as described
in the MaintenanceB ooklet. This may
otherwise lead to increased wear and
damage to the major assemblies or the
vehicle.
Aq ualified specialist workshop, e.g. an
authorize dMercedes-Ben zCenter, will reset
the ASSYST PLUS servic einterval display
after the servic ework has been carried out.
You can also obtain further information on
maintenanc ework, for example.
Special service requirements
The specified maintenanc einterval takes only
the normal operation of the vehicle into
account. Under arduous operatin gconditions
or increased load on the vehicle,
maintenanc ework must be carried out more
frequently, for example:
R regular city driving with frequent
intermediate 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 engin eisoften left idling for long
periods
Under these or similar conditions ,have, for
example, the air filter, engin eoil and oil filter
replaced or changed more frequently. Under
arduous operatin gconditions ,the tires must
be checked more often .Further information
can be obtained at aqualified specialist
workshop, e.g. an authorized Mercedes-Benz
Center.

When handling engine oil, observe the
important safety notes on service products
(Y page 347).
The engine oils are matched to the
performance of Mercedes-Benz engines and
service intervals. You should therefore only
use engine oils and oil filters that are
approved for vehicles with maintenance
systems.
For alist of approved engine oils and oil filters,
consult an authorized Mercedes-Benz
Center .Orvisit the website
http://bevo.mercedes-benz.com.
The table shows which engine oils have been
approved for your vehicle. Model Engine

Do no tuse any additives in the engine oil.
This could damage the engine. Engineo
il viscosity Viscosity describes the flow characteristics
of
afluid. If an engine oil has ahigh viscosity,
this means that it is thick; alow viscosity
means that it is thin.
Select an engine oil with an SAE classification
(viscosity) suitablef or the prevailing outside
temperatures. The table shows you which
SAE classifications are to be used. The low-
temperature characteristics of engine oils
can deteriorate significantly, e.g. as aresult
of aging, soot and fuel deposits. It is therefore
strongly recommended that you carry out
regularo il changes using an approved engine
oil with the appropriate SA Eclassification. Brake fluid
G
WARNING
The brak efluid constantly absorb smoisture
fro mt he air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
fluid is too low, vapor pockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is arisk of an accident.
You should have the brake fluid renewed at
the specified intervals.
When handling brake fluid, observe the
important safety notes on service products
(Y page 347).
The brake fluid change intervals can be found
in the MaintenanceB ooklet.350
