The optional equipment supplied with your
vehicle includes two KEYLESS GO keys. KEY-
LESS GO allows you to lock/unlock and start
the vehicle simply by carrying the KEYLESS
GO key with you. When you touch the surface
of the sensors on the vehicle's door handles,
KEYLESS GO establishes a radio connection
between the vehicle and the key.

handle or press the button on the tailgate
handle (Estate), your vehicle unlocks cen-
trally if the factory settings have not been
changed:
R the doors
R the boot lid/tailgate
R the fuel filler flap
When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid
KEYLESS GO key is in the vehicle by periodi-
cally establishing radio contact. G
Risk of accident
If children are left unsupervised in the vehi-
cle, they could open a door from the inside,
even if it has been locked. Or they could
start the vehicle if a valid KEYLESS GO key is in the vehicle and they press the KEY-
LESS GO button on the gear selector lever.
They could endanger themselves and oth-
ers. Never leave children unsupervised in
the vehicle. Switch off the engine and take
the KEYLESS GO key with you, even if you
are only leaving the vehicle for a short time. 1

Rear-seat heating
i The system automatically switches down
from level 3to level 2after approximately
five minutes.
The system automatically switches down
from level 2to level 1after approximately
ten minutes.
The system automatically switches off
approximately 20 minutes after it is set to
level 1.
X Make sure that the key is in position 1or
2 in the ignition lock.
X To switch on: press button1repeatedly
until the desired heating level is set.
X To switch off: press button1repeatedly
until all indicator lamps go out. i
If the battery voltage is too low, the seat
heating may switch off. Folding bench seat in the luggage
compartment* (Estate)
i The folding bench seat in the luggage
compartment* is only suitable for persons
no more than 1.40 m tall and weighing a
maximum of 50 kg.
Secure children as recommended
(Y page 47).
The combined luggage cover and net must
be fitted if you are using the folding bench
seat. G
Risk of injury
If you are using the folding bench seat in
the luggage compartment, the backrests
on the rear bench seat must be upright and
locked.
Only start the journey once the head
restraints for the folding bench seat are
correctly positioned. Adjust the head
restraint so that the back of the seat occu-
pant's head is supported at about eye level.
This reduces the risk of injury to the child
in an accident. Make sure that the seat belt is correctly
routed across the body and that the seat
belt tongue is engaged in the buckle. G
Risk of injury
Only replace damaged covers with genuine
Mercedes-Benz covers.
Never leave children unsupervised in the
vehicle. This applies even if they are
secured by a child restraint system.
Make sure that luggage and other items are
adequately secured.
People could otherwise be injured as a
result of the load being thrown around in
the event of sharp braking, a sudden
change in direction or an accident. Controls

Light switch
For reasons of safety, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, daytime operation of headlamps varies
due to legal requirements and self-imposed
obligations. In these countries, the dipped-
beam headlamps are automatically switched
on when the engine is started.
i If you drive in countries in which traffic
drives on the opposite side of the road to
the country where the vehicle is registered,
oncoming traffic may be dazzled by the
asymmetrical dipped-beam headlamps.
Have the headlamps changed to symmet-
rical dipped beam when driving in these
countries. You can obtain information
about this from any Mercedes-Benz Service
Centre. $

Make sure that the key is in position 2of
the ignition lock or that the engine is run-
ning.
X To switch on: turn the light switch to

The dipped-beam headlamps, parking
lamps and licence plate lamps are switched
on. The green dipped-beam indicator lamp
in the instrument cluster light up.
Constant headlamp mode In countries in which constant headlamp
mode is not a legal requirement, you can
make this setting using the on-board com-
puter.
You can activate or deactivate "constant
headlamp mode" using the on-board com-
puter (Y page 135). Controls

tion* on/off

Risk of poisoning
Exhaust fumes are produced when the aux-
iliary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You
should therefore switch off the auxiliary
heating in confined spaces without an
extraction system, e.g. a garage. G
Risk of fire
When operating the auxiliary heating, parts
of the vehicle may become very hot, and
highly inflammable material such as fuels
could be ignited. Operating the auxiliary
heating is thus prohibited at filling stations
or when your vehicle is being refuelled. You must therefore switch off the auxiliary heat-
ing at filling stations.
The auxiliary heating heats the air in the vehi-
cle interior to a temperature between 20 †
and 24 †, without depending on heat emitted
by the running engine. The auxiliary heating
is operated using fuel directly from the vehi-
cle's fuel tank. For this reason, the tank con-
tent must be at least at reserve fuel level to
ensure that the auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before activating X
Make sure that the key is in position 2in
the ignition lock.
X Set the temperature to a value between
20 † and 24 †.
The auxiliary heating/ventilation can be acti-
vated even when the air conditioning is being controlled manually. Optimum comfort can
be attained when the system is set to auto-
matic mode. Set the desired temperature
within this range. If a higher temperature is
set, the vehicle is heated to 24 †. If a lower
temperature is set, the vehicle is heated to
20 †.
Activating/deactivating the auxiliary
heating/ventilation
The auxiliary heating/ventilation can be acti-
vated or deactivated using the remote control
or the button on the centre console.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y

To engage the mobile phone
2 Connector contact
3 Mobile phone bracket
X Slide the lower end of the mobile phone
into connector contact 2in mobile phone
bracket 3.
X Push the top part of the mobile phone in
the direction of arrow 1until it engages in
mobile phone bracket 3.
The mobile phone is connected to the
hands-free system and to the multi-func-
tion steering wheel.
The battery is charged depending on the
charge status and the position of the key in
the ignition lock. The charging process is
shown in the mobile phone display. i
The system reads the phone book stored
on the SIM card and in the mobile phone
memory. If the same entry is stored in both
of the phone books, both of these entries
will be shown in the multi-function display.
You can make a call using the sand
t buttons on the multi-function steering
wheel. You can control other mobile phone
functions via the on-board computer
(Y page 141).
i When you remove the key from the igni-
tion lock, the mobile phone remains
switched on for approximately ten minutes
(run-on time). If you make a call during this
time, the mobile phone will be switched off
approximately ten minutes after you have
ended the call.
Run-on time:
You can change the run-on time by making
an additional phone book entry on the SIM
card. For the name, enter "Idletime" and for
the number, enter a figure between "1" and
"30" (minutes). If you have not entered a
number or have entered a different num-
ber, the run-on time of ten minutes will still
apply. For information on how to create a phone
book entry, refer to the mobile phone oper-
ating instructions.
Own number sending:
The hands-free system does not recognise
whether own number sending is enabled or
disabled in the mobile phone. The phone
number is therefore always sent by default.
By creating an additional phone book entry
on the SIM card, you can switch the own
number sending function on and off. For
the name, enter "CALLID" and for the num-
ber, enter a "0" or a "1". Entering "0" will
prevent the telephone number from being
sent; entering "1" will allow it to be sent.
For information on how to create a phone
book entry, refer to the mobile phone oper-
ating instructions.Controls
