recirculation mode
General notes You can also temporarily deactivate the flow
of fresh air manually if unpleasant odors are
entering the vehicle from outside. The air
already inside the vehicle will then be
recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in
particular at low temperatures. Only use air-
recirculation mode briefly to prevent the
windows from fogging up.

heat function
General notes Vehicles with rear-compartment climate
control:
once the engine is switched off, it is
possible to make use of the residual heat of
the engine to continue heating or ventilating
the rear and front compartment of the vehicle
for approximately 15 minutes. If the "Residual
heat" function is set for only the front or only
the rear compartment, it is possible to
continue heating or ventilating for
approximately 30 minutes.
Vehicles without rear-compartment
climate control: once the engine is switched
off, it is possible to make use of the residual
heat of the engine to continue heating or
ventilating the front compartment of the
vehicle for approximately 30 minutes. Operating the climate control systems

WARNING
If children open the perfume vial, they could
drink the perfume or it could come into
contact with their eyes. There is a risk of
injury. Do not leave children unsupervised in
the vehicle.
If the perfume liquid has been drunk, consult
a doctor. If perfume comes into contact with
your eyes or skin, rinse the eyes with clean
water. If you continue to experience
difficulties, consult a doctor. 0043

The perfume atomizer helps to improve
driving comfort.
Using COMAND, you can:
R switch the perfume atomizer on and off
R regulate the perfume intensity
See the separate operating instructions. 164

i
The following conditions can affect your
perception of the perfume intensity:
R operating mode of the automatic climate
control
R interior temperature
R time of year/day
R air humidity
R physiological condition of occupants,
e.g. fatigue or hunger
The perfume atomizer can only be operated
when the automatic climate control is
switched on.
The perfume atomizer is provided with a pre-
filled perfume vial. You can also choose from
a variety of filled perfume vials and an empty
vial which you can fill yourself.
! If you do not use genuine Mercedes-Benz
interior perfumes, observe the
manufacturers' safety notices on the
perfume packaging.
i Do not refill the pre-filled perfume vial
when it is empty. Dispose of the used vial
after use.
X To insert the perfume vial: open the glove
box (Y page 317).
X Slide the perfume vial into the holder as far
as it will go.
X To remove the perfume vial: pull out the
perfume vial.
X To refill the perfume vial: unscrew the lid
of the empty perfume vial to refill it
yourself.
X Refill the vial with a maximum of 15 ml of
the desired liquid perfume.
X Screw the lid back on to the vial.
! Only refill the vial when you are outside
the vehicle. Otherwise, liquid perfume
could drip into the interior and contaminate
it.
i Always refill the empty refillable vial with
the same perfume. Otherwise, you might not achieve optimum results from the
perfume atomizer. Operating the climate control systems

You can use the "Ionization" function to purify
the air in the vehicle interior and attain an
improved interior climate.
The ionization of the interior air is odorless
and cannot be perceived directly in the
vehicle interior.
You can switch ionization on and off using
COMAND (see the separate operating
instructions).
Ionization can only be switched on if the front
automatic climate control is activated. The
side air vent on the driver's side must be
open. Setting the air vents

WARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air outlets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windshield
and the hood free of blockages, such as ice,
snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior. Setting the center air vents

Useful information
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 note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: (Y page 27).Notes on breaking-in a new vehicle
Important safety notes
The sensors of certain drive and driving safety
systems automatically reset during driving for
a certain distance after the vehicle has been
delivered or after repairs have been carried
out. Complete system effectiveness is
reached only after completion of this teach-
in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after
several hundred kilometers of driving.
Compensate for this by applying greater force
to the brake pedal. The first 1000 miles(1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
R You should therefore drive at varying
vehicle and engine speeds for the first
1000 miles (1500 km).
R Avoid heavy loads, e.g. driving at full
throttle, during this period.
R When shifting gears manually, upshift in
good time, before the tachometer needle
reaches 00C3of the way to the red area of the
tachometer. R
Do not manually shift to a lower gear to
brake the vehicle.
R Try to avoid depressing the accelerator
pedal beyond the point of resistance
(kickdown).
R All vehicles (except AMG vehicles):
ideally, for the first 1,000 miles (1,500 km),
drive in program E.
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate
the vehicle to full speed.
Additional breaking-in notes for AMG
vehicles:
R Do not drive faster than 85 mph
(140 km/h) for the first 1,000 miles
(1,500 km).
R Only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R Change gear in good time.
R Ideally, for the first 1,000 miles (1,500 km),
drive in program C.
You should also observe these notes on
breaking in if the engine or parts of the drive
train on your vehicle have been replaced.
Always observe the respective speed limits. Driving
Important safety notes

WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle
is jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another. 170
