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:
Ryou drive at low speeds.
Rthe tires have adequate tread depth.
For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
Rlower your speed.
Ravoid ruts.
Ravoid sudden steering movements.
Rbrake 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 compo-
nents in the engine or the automatic trans-
mission. Water can also be drawn in by the
engine's air suction nozzles and this can
cause engine damage.
Winter driving
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the 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
facing into the wind.
Have your vehicle winter-proofed at a quali-
fied specialist workshop at the onset of win-
ter.
Drive particularly carefully on slippery road
surfaces. Avoid sudden acceleration, steeringand braking maneuvers. Do not use cruise
control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift 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 a short 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. The
vehicle could skid if you fail to adapt your
driving style. Always adapt your driving style

Correct use
Observe the following information when using
COMAND:
Rthe safety notes in this manual
Rtraffic rules and regulations
Rlaws and safety standards pertaining to
motor vehicles
iWork improperly carried out on electronic
components or systems (e.g. radio, DVD
changer) and associated software could
cause them to cease functioning. Even sys-
tems that have not been modified could be
affected because the electronic systems
are connected. Electronic malfunctions
can seriously jeopardize the operational
safety of your vehicle.
iRoof antenna functionality (telephone,
satellite radio, GPS) can be affected by the
use of roof carrier systems.
Attaching metalized retrofit film to the
windshield may affect radio reception and
have a negative impact on all other anten-
nas (e.g. emergency antenna) in the vehicle
interior.
iTherefore, have all work on or modifica-
tions to electronic components carried out at a qualified specialist workshop. This
workshop should have the necessary spe-
cialist knowledge and tools to carry out the
work required. Mercedes-Benz recom-
mends that you use an authorized
Mercedes-Benz Center for this purpose. In
particular, work relevant to sa
fety or on
safety-related systems must be carried out
at a qualified specialist workshop.
iProtection against theft: this device is
equipped with technical provisions to pro-
tect it against theft. Further information on
protection against theft can be obtained
from an authorized Mercedes-Benz Center.
Operating safety285
COMAND
Z
COMAND can give incorrect navigation com-
mands if the actual street/traff icsituation
does not correspond with the digital map's
data. Dig ital maps donot cover all areas nor
all routes inan area. For example, a route may
have been diverted or the direction of a one-
way street may have changed.
For th isreason, you must always observe
road and traff icrules and regulations during
your journey. Road and traffic rules and reg-
ulations always have priority over the sys-
tem's driving recommendations.
Navigation announcements are intended to
dire ct you whiledriving without diverting your
attention from the road and driving.
Please always use this feature instead of con-
sulting the map display for directions. Look-
ing at the icons or map display can distract
you from traffic cond itions and driving, and
increase the risk of an accident.
General notes
Operational readiness of the navigation
system
The navigation system must determine the
position of the vehicle before first use or
whenever operational status isrestored.
Therefore, you may have to drive for a while
before precise route guidance ispossible.
GPS reception
Among other things, correct functioning of
the navigation system depends on GPS recep-
tion. Incertain situations, GPS reception may
be impaired, there may beinterference or
there may beno reception at all,e.g. in tun-
ne lsor parking garages.
iUsing roof carriers may impair the correct
functioning of a roof antenna (phone, sat-
ellit e radio, GPS).
Entry restriction
On veh icles for certain countries, there isa
restriction on entering data.
The restriction isactive from a vehicle speed
of above approximately 3 mph (5 km/h).As soon as the speed falls below approximately
2 mph (3 km/h), the restriction becomes
inactive.
When the restriction is active, certain entries
cannot be made. This will be indicated by the
fact that certain menu items are grayed out
and cannot be selected.
The following entries are not possible, for
example:
Rentering the destination city and street
Rentering a destination via the map
Rentering POIs in the vicinity of a city or via a
name search
Rediting entries
Rusing the number keypad for direct entry
Other entries are possible, such as entering
points of interest in the vicinity of the desti-
nation or current position.

should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked.
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
Washing the vehicle and cleaning the
paintwork
Automatic car wash
GWARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored.
!If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations.
To prevent damage to the vehicle, deacti-
vate DISTRONIC PLUS and the HOLD func-
tion in the following or other similar situa-
tions:
Rwhen towing the vehicle
Rin the car wash
!It is preferable to use car washes with
adjustable high-pressure pre-cleaning that
corresponds to the specification for the
Cabriolet program. In car washes that use
high water pressures, there is a risk that a
small amount of water may leak into the
vehicle.
!Vehicles with HANDS-FREE ACCESS: if a
SmartKey with KEYLESS-GO is within the
detection range of the KEYLESS-GO
antenna, the following situations could lead
to the unintentional opening of the trunk
lid:
Rusing a car wash
Rusing a power washer
Make sure that the SmartKey is at least
6.5 ft (2 m) away from the vehicle.
!Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
If you have your vehicle cleaned in a high-
pressure automatic car wash, small
amounts of water may enter the vehicle.
!Make sure that the automatic transmis-
sion is in position Nwhen washing your
vehicle in a tow-through car wash. The vehi-
cle could be damaged if the transmission is
in another position.
!Make sure that:
Rthe side windows and the roof are com-
pletely closed
Rthe climate control blower is switched off
Rthe windshield wiper switch is at position
0
The vehicle could otherwise be damaged.
You can wash the vehicle in an automatic car wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
shield.
Washing by hand
In some countries, washing by hand is only
allowed at specially equipped washing bays.
