Switching the auxiliary heating/venti-

Your vehicle comes with one remote control.
You may use two additional remote controls
for your vehicle. For more information, please
contact a qualified specialist workshop.
The remote control has a maximum range of
approximately 300 metres. This range is
reduced by:
R sources of radio interference
R solid objects between the remote control
and the vehicle R
the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
i The optimum range can be achieved if you
hold the remote control vertically, pointing
upwards when you press one of the but-
tons.
i Abattery symbol appears in the display
when the battery in the remote control is
low. Replace the remote control battery
(Y page 151).

Important safety notes G
WARNING
ATTENTION ASSIST is only an aid and may
detect your tiredness or lapses in concentra-
tion too late or not at all. It is not asubstitute
for a well rested and attentive driver.
Fatigue may cause you to recognise hazard-
ous situations too late, misjudge a situation
or react slower. For this reason, make sure
you feel rested before you begin driving and
during your journey. Always take breaks in
good time and regularly, especially during
long journeys. Otherwise, you may fail to rec-
ognise dangers in time, cause an acciden tand
injure yoursel fand others.
General notes ATTENTIO
NASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 80 km/h
to 180 km/h range. If ATTENTION ASSIST detects typical indica-
tors of fatigue or increasing lapses in con-
centration on the part of the driver, it sug-
gests taking a break.
ATTENTIO
NASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R journey-related parameters, e.g. time of
day, length of journey
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or
not occur at all:
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong sid ewind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently using COMAND APS or
making a telephone call with COMAND APS
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed
Warning and display messages in the
multifunction display Example: vehicles with automatic transmission
If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after your
journey has begun. You the
nhear an inter-
mittent warning tone twice and the Atten‐ tion Assist: Drowsiness detected mes-
sage appears in the multifunction display. 208
Driving systemsDriving and parking

You will find the values approved by the man-
ufacturer on the vehicle identification plates
and those for the towin
gvehicle in the "Tech-
nical data" section (Y page 381).
When towing a trailer, your vehicle's handling
characteristics will be differen tincomparison
to when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning circle
This could impair the handling characteris-
tics. Adapt your style of driving accordingly.
Maintain a safe distance. Drive carefully.
When towing a trailer, always adjust your
speed to the current road and weather con-
ditions. Do not exceed the maximum permis-
sible speed for your vehicle/trailer combina-
tion. Notes on towing
atrailer
General notes !
Use a drawbar noseweigh tas close as
possible to the maximum permissible nose-
weight. Do not use a noseweight of less
than 50kg, otherwise the trailer may come
loose.
Note that the payload and the rear axle load
are reduced by the actual payload.
i When towing a trailer, set the tyre pres-
sure on the rear axle of the towing vehicle
for a maximum load; see the tyre pressure
table in the fuel filler flap (Y page 343).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 380).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 75 kg. Missing values for the
E500 BlueEFFICIENCY
model were not available at the time of going
to print. However, the actual noseweight
must not exceed the value give nonthe trailer
tow hitch and trailer identification plates. The
lowest weight applies.
Please note that when towing a trailer, PARK-
TRONIC (Y page 200) and Parking Guidance
(Y page 203) are only available with limita-
tions, or not at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use a trailer with a height-adjustable draw-
bar.
Driving tips i
Observe the notes on ESP ®
trailer stabi-
lisation (Y page 68).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the max-
imum permitted speed is. Observe the legally
prescribed maximum speed in the relevant
country.
For certain Mercedes-Ben zvehicles, the max-
imum permissible rear axle load is increased
when towing a trailer. Refer to the "Technical
data" section to find out whether this applies
to your vehicle. If you utilise any of the added
maximum rear axle load when towing a trailer,
the vehicle/trailer combination may not
exceed a maximum speed of 100 km/h for
reasons concerning the operating permit.
This also applies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be differen tincomparison
to when driving without a trailer and it will
consume more fuel.
Change into a lower gear in good time on long
and steep downhill gradients. Towing

Important safety notes G
WARNING
Observe the legal requirements of the country
in which you are currently driving regarding
operating mobile communications equipment
in a vehicle.
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.
Two-way radios and fax equipment used with-
out low-reflectio nexterior aerials can inter-
fere with the vehicle's electronics and thereby
jeopardise the operating safety of the vehicle
and your safety .Therefore, you must only use
this equipment if it is correctly connected to
a separate reflection-free exterior aerial. G
WARNING
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior aerial takes
into account current scientific discussions
relating to the possible health risk posed by
electromagnetic fields.
Mercedes-Ben zrecommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in
the vehicle
R mutual influences between the vehicle
electronics and mobile phones are mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by a wireless device to the exterior.
R the field strength in the vehicle interior is
lower than in a vehicle that does not have
an exterior aerial. i
There are various mobile phone brackets
that may be fitted in your vehicle; in some
cases, these are country-specific.
i You can connect a Bluetooth ®
-capable
mobile phone with Audio 20, Audio 50 or
COMAND Online via the Bluetooth ®
inter-
face. This also applies if your vehicle is
equipped with convenience telephony.
More information on suitable mobile phones,
mobile phone brackets and on connecting
Bluetooth ®
-capable mobile phones with
Audio 20, Audio 50 or COMAND Online can
be obtained:

you use the phone depend on your mobile
phone model and service provider.

phone bracket, you can speak to the person
you are calling using the hands-free system.
