Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.
Overview of climate control systems
Important safety notes
GWarning
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.
GWarning
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise, the windows could fog up,
impairing visibility and endangering you and
others.
Dual-zone automatic climate control controls
the temperature and the humidity of the
vehicle interior and filters out undesirable
substances from the air.
Dual-zone automatic climate control is only
operational when the engine is running.
Optimum operation is only achieved when
you drive with the side windows and tilt/
sliding sunroof/panorama roof with power
tilt/sliding panel closed.
i Ventilate the vehicle for a brief 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 can filter out most
particles of dust and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.120Overview of climate control systemsClimate control

General driving tips
Important safety notes
GWarning
Please do not forget that your primary
responsibility is to drive the vehicle. A driver's
attention to the road must always be his/her
primary focus when driving. For your safety
and the safety of others, we recommend that
you pull over to a safe location and stop
before placing or taking a telephone call.
If you use the telephone18 while driving,
please use the hands-free device and only use
the telephone when road, weather and traffic
conditions permit. Some jurisdictions prohibit
the driver from using a mobile telephone while
driving a vehicle.
Only operate the audio system or
COMAND18 (Cockpit Management and Data
System) if road, weather and traffic
conditions permit. Otherwise, you may not be
able to observe traffic conditions and could
endanger yourself and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
Drive sensibly – save fuel
To save fuel, observe the following notes:
XKeep tires at the recommended inflation
pressures.
XRemove unnecessary cargo.XRemove the roof rack when not in use.XMaintain a low engine speed until the
engine is warm.
XAvoid frequent acceleration and
deceleration.
XHave all maintenance work performed at
the service intervals specified in the18Observe all legal requirements.150Driving tipsDriving and parking

Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth
on the road surface, there is a danger of
hydroplaning occurring, even if:
R you drive at low speeds
R the tires have adequate tread depth
For this reason, in the event of heavy rain or
in conditions in which hydroplaning can occur
you must drive in the following manner:
R Lower your speed
R Avoid ruts
R Brake carefully
Driving on flooded roads
! Do not drive through flooded areas.
Check the depth of any water before driving
through it. Drive slowly through standing
water. Otherwise, water may enter the
vehicle interior or the engine compartment.
This can damage the electronic
components in the engine or the automatic
transmission. Water can also be drawn in
by the engine's air suction nozzles and this
can cause engine damage.
Winter driving
General information
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at an authorized
Mercedes-Benz Center, at the onset of
winter.
Observe the notes in the "Winter operation"
section ( Y page 155).
Winter tires
At temperatures below 45 ‡(+7 †), use
winter tires or all-season tires. Both types of
tire are identified by the M+S marking.
Only winter tires also bearing the i
snowflake symbol next to the M+S marking
provide the best possible grip in wintry road
conditions. Only these tires will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter, as these tires
have been designed specifically for driving on
snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling
characteristics.GWarning
M+S tires with a tread depth of less than 1
/ 6
inch (4 mm) must be replaced. They are no
longer suitable for winter operation.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
Once you have installed the winter tires:
XCheck the tire pressures ( Y page 275).XRestart the tire pressure monitor
( Y page 277).GWarning
If you use your spare wheel when M+S tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may very
well impair turning stability and that overall
driving stability may be reduced. Adapt your
driving style accordingly.
Have the spare wheel replaced by a regular
road wheel with an M+S tire at the nearest
authorized Mercedes-Benz Center.
Snow chains
For safety reasons, Mercedes-Benz
recommends that you only use snow chains
which have been specially approved for your
vehicle by Mercedes-Benz, or are of a
corresponding standard of quality.
! There is not enough space for snow
chains on some wheel sizes. Observe the
information under "Tires and wheels" in the
"Technical Data" section to avoid damage
to the vehicle or the wheels.

Roof carrier
Important safety notes
GWarning!
Only use roof racks approved by Mercedes-
Benz for your vehicle model to avoid damage
to the vehicle.
Follow the manufacturer's installation
instructions. Otherwise, an improperly
attached roof rack system or its load could
become detached from the vehicle.
Do not exceed the maximum roof load of
220 lb (100 kg).
Take into consideration that when the roof
rack is loaded, the handling characteristics
are different from those when operating the
vehicle without the roof rack loaded.
! Mercedes-Benz recommends that you
only use roof carriers that have been tested
and approved for Mercedes-Benz vehicles.
This helps to prevent damage to the
vehicle.
Position the cargo on the roof rack in such
a way that the vehicle will not sustain
damage even when it is in motion.
Depending on the vehicle equipment,
ensure that when the roof carrier is
installed you can:
Rraise the tilt/sliding sunroof fully
Ropen the panorama roof with power tilt/
sliding panel fully
Ropen the trunk lid fully
! To avoid damaging or scratching the
covers, do not use metallic or hard objects
to open them.
Fastening the roof carrier
XOpen covers : carefully in the direction of
the arrow.
XFold covers : upwards.XOnly secure the roof carrier to the
anchorage points under covers :.
XObserve the manufacturer's installation
instructions.
