the draught for the driver and passengers in
both the fronta nd the rear compartment in a
vehicle with the soft top down. You can open
or close AIRCAP either when the vehicle is
stationary or when driving up to aspeed of
160 km/h. AIRCAP has the following components:

Loading guidelines (Coupé)
G
Risk of injury
Secure and position the load as described in
the loading guidelines.
Otherwise, vehicle occupant scould
be injured by the load being thrown around in
the event of sharp braking, asudden change
in direction or an accident.
You will find further information in the "Secur-
ing aload" section.
Even if you follow all the loading guidelines,
the load will increase the risk of injury in the
event of an accident. G
Risk of poisoning

The handling characteristics of
aladen vehi-
cle are dependent on the distribution of the
load within the vehicle. For this reason, you
should observe the following notes when
transportin gaload:
R never exceed the maximum permissible
gross vehicle weight or the permissible axle
loads for the vehicle (including occupants).
R position heavy loads as far forwards and as
low in the boot as possible.
R the load must not protrude above the upper
edge of the seat backrests.
R alway splace the load against the rear or
fronts eat backrests. Make sure that the
seat backrest sare securely locked into
place.
R alway splace the load behind unoccupied
seats if possible.
R secure the load with sufficiently stron gand
wear-resistan tload restraints. Pad sharp
edges for protection.
i Load restraints are available at any quali-
fied specialist workshop, e.g. aMercedes-
Benz Servic eCentre. Stowage compartments
G
Risk of injury
The stowage compartmentsm ust be closed
when items are stored in them. Luggage nets
are not designed to secure heavy items of
luggage.
You or other vehicle occupant scould be
injured by object sbeing thrown around if you:
R brake sharply
R change direction suddenly
R are involved in an accident
Sharp-edged and fragile object smust not be
placed in the luggage net. Do not place hard object
sinthe map pockets.
Object smust not protrude from the map
pockets.

Dependin gonthe vehicle's equipment,
there is an AUX-IN connection installed in
the glove compartment,oraM edia Inter-

portable audio equipment, e.g. for an iPod
or USB device; see the separate Audio or

in which you are currently driving regarding
operating mobile communications equipment
in av ehicle.
If it is permitted by law to operate communi-
cations equipment while the vehicle is in
motion, you must only do so if the traffic sit-
uation permits. Otherwise, you could be dis-
tracted from the traffic conditions, cause an
accident and injure yourself and others.

The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign object.
In the event of asudden loss of pressure, bring
the vehicle to ahalt by braking carefully. Do
not make any sudden steerin gmovements
when doing so.
The function of the tyre pressure loss warning
system is limited or delaye dif:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towing avery heavy or large trailer.
R you are driving with aheavy load (in the
vehicle or on the roof).

ing system Restart the tyre pressure loss warning system
if you have:
R
changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler flap
to ensure that the tyre pressure in all four
tyres is set correctly for the respective
operating conditions.
X Observe the notes in the section on tyre
pressures (Y page 186). G
Risk of accident
The tyre pressure loss warning system can
only give reliable warnings if you have set the
correc ttyre pressure.
If an incorrect tyre pressure is set, these
incorrect values will be monitored.
At yre with insufficien tpressure results in
vehicle instability when driving, thus increas-
ing the risk of an accident.
