Protecting the environment
General notes
HEnvironmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected by these factors:
Roperating conditions of your vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
Ravoid short trips as these increase fuel con-
sumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer need
them.
Ra regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
Ralways have service work carried out at a
qualified specialist workshop.
Personal driving style:
Rdo not depress the accelerator pedal when
starting the engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintain a safe distance
from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each gear
only up to Ôof its maximum engine speed.
Rswitch off the engine in stationary traffic.
Rkeep an eye on the vehicle's fuel consump-
tion.
Environmental concerns and recom-
mendations
Wherever the operating instructions require you
to dispose of materials, first try to regenerate or
re-use them. Observe the relevant environmen-
tal rules and regulations when disposing of
materials. In this way you will help to protect the
environment.
Genuine Mercedes-Benz parts
HEnvironmental note
Daimler AG also supplies reconditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the
same Limited Warranty entitlements as new
parts.
!Air bags and Emergency Tensioning Devi-
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
Rdoors
Rdoor pillars
Rdoor sills
Rseats
Rcockpit
Rinstrument cluster
Rcenter console
Do not install accessories such as audio sys-
tems in these areas. Do not carry out repairs or welding. You could impair the operating
efficiency of the restraint systems.
Have aftermarket accessories installed at a
qualified specialist workshop.
You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels as
well as accessories relevant to safety which
have not been approved by Mercedes-Benz. This
could lead to malfunctions in safety-relevant

Introduction

Locking/unlocking centrally
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry the
SmartKey with you. You can combine the func-
tions of KEYLESS-GO with those of a conven-
tional SmartKey. Unlock the vehicle by using
KEYLESS-GO, for instance, and lock it using the
&button on the SmartKey.
The driver's door and the door at which the han-
dle is used, must both be closed. The SmartKey
must be outside the vehicle. When locking or
unlocking with KEYLESS-GO, the distance
between the key and the corresponding door
handle must not be greater than 3 ft (1 m).
A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example:
Rwhen starting the engine
Rwhile driving
Rwhen using HANDS-FREE ACCESS
Rwhen the external door handles are touched
XTo unlock the vehicle: touch the inner sur-
face of the door handle.
XTo lock the vehicle: touch sensor surface :
or ;.
Make sure that you do not touch the inner
surface of the door handle.
XConvenience closing feature: touch
recessed sensor surface ;for an extended
period.
Further information on the convenience clos-
ing feature (
Ypage 87).
Deactivating and activating
If you do not intend to use a SmartKey for an
extended period of time, you can deactivate the
KEYLESS-GO function of the key. The SmartKey will then use very little power, thereby conserv-
ing battery power. For the purposes of activa-
tion/deactivation, the vehicle must not be
nearby.
XTo deactivate: press the&button on the
SmartKey twice in rapid succession.
The battery check lamp (
Ypage 76) of the
SmartKey flashes twice briefly and lights up
once, then KEYLESS-GO is deactivated.
XTo activate: press any button on the Smart-
Key.
or
XInsert the SmartKey into the ignition lock.
KEYLESS-GO and all of its associated features
are available again.
Changing the settings of the locking
system
You can change the settings of the locking sys-
tem. This means only the driver's door, the lock-
able stowage compartments in the vehicle inte-
rior and the fuel filler flap are unlocked when the
vehicle is unlocked. This is useful if you fre-
quently travel alone.
XTo change the setting: press and hold down
the % and& buttons simultaneously
for about six seconds until the battery indica-
tor lamp (
Ypage 76) flashes twice.
If the setting of the locking system is changed
within the signal range of the vehicle, pressing
the & or% button:
Rlocks or
Runlocks the vehicle
The SmartKey now functions as follows:
XTo unlock: press the%button once.
XTo unlock centrally: press the%button
twice.
XTo lock centrally: press the&button.
The KEYLESS-GO function is changed as fol-
lows:
XTo unlock the driver's door: touch the inner
surface of the door handle on the driver's
door.
XTo unlock centrally: touch the inner surface
of the driver or front-passenger door handle.
XTo lock centrally: touch the outer sensor
surface on one of the door handles.

Opening and closing

Roof
Important safety notes
GWARNING
If you do not fully open/close the soft top, the
soft-top hydraulics depressurize after a short
time. This causes the soft top to lower unex-
pectedly and may cause you or others to be
trapped. There is a risk of injury.
Always open or close the soft top completely.
GWARNING
Closing the roof manually is a complicated
and technically demanding procedure, which
requires a lot of strength. You or others can
become trapped. There is a risk of injury.
Only have the soft top closed manually at a
qualified specialist workshop.
!Never sit on the rear compartment trim or
stow heavy objects there. You will otherwise
damage the roof and rear compartment trim
of the vehicle.
!Do not forget that the weather can change
abruptly. Make certain that the roof is closed
when you leave the vehicle. The vehicle elec-
tronics can be damaged if water enters the
vehicle interior.
!When opening and closing the roof, make
sure that:
Rthere is sufficient clearance, as the roof
swings upwards.
Rthere is sufficient clearance behind the
vehicle, as the trunk lid swings backwards
beyond the bumper.
Rthe trunk is only loaded to below the trunk
partition.
Rthe trunk partition is not pushed up by the
load.
Rthe trunk partition is closed.
Rthe trunk lid is closed.
Rthe outside temperature is above 5 ‡
( Ò15 †).
You could otherwise damage the roof, trunk
and other parts of the vehicle.
The vehicle dimensions for opening/closing the
roof can be found in the "Vehicle data" section
(
Ypage 317). Make sure that the roof and rear window are
clean and d
ry before opening the roof. Other-
wise, water or dirt could enter the vehicle inte-
rior or trunk.
Opening and closing using the roof
switch
Important safety notes
GWARNING
When opening or closing the roof, body parts
could be trapped by, for example, the roof
mechanism, trunk lid or side windows. There
is a risk of injury.
When raising or lowering the roof, make sure
that no body parts are in the vicinity of moving
components. If someone becomes trapped,
release the button.
For safety reasons, you can only open or close
the roof when the vehicle is stationary.
!Operating the roof while pulling away:
RObserve the following traffic carefully.
RDo not drive faster than 25 mph (40 km/h).
RAvoid abrupt braking and swerving maneu-
vers.
Do not operate the roof when cornering, driv-
ing on uneven surfaces or during strong
winds. The vehicle may otherwise be dam-
aged.
iIf the traffic conditions mean that you have
to drive off while opening/closing the roof,
the procedure which was started while sta-
tionary can be continued at speeds of up to
approximately 25 mph (40 km/h).

MAGIC SKY CONTROL
General notes
MAGIC SKY CONTROL is a panorama roof, the
transparency of which can be changed by apply-
ing electrical voltage.
MAGIC SKY CONTROL can be switched between
darkened and transparent states.
MAGIC SKY CONTROL darkens automatically
after a short period when you turn the SmartKey
to position uin the ignition lock or remove the
SmartKey.
Risk of electric shock
GDANGER
MAGIC SKY CONTROL operates using high
voltage. If the trim behind the overhead con-
trol panel is damaged or removed, electrical
components will be exposed. If you touch
these components, you could get an electric
shock. There is a risk of fatal injury.
RNever remove the trim behind the overhead
control panel.
RIf the trim is damaged, never touch the
electrical components behind it.
RAlways have work on the MAGIC SKY CON-
TROL carried out at a qualified specialist
workshop.
The electrical components of MAGIC SKY CON-
TROL are protected by a paneling behind the
overhead control panel.
The MAGIC SKY CONTROL control unit is
marked with a yellow warning sticker that warns
you of high voltage. The electric cables of the
high-voltage section are color orange.
Operating MAGIC SKY CONTROL
XTurn the SmartKey to position 1or2 in the
ignition lock.
MAGIC SKY CONTROL switches to the status
it was set to before the engine was switched
off.
XTo change the degree of transparency:

The hazard warning lamps automatically switch
on if:
Ran air bag is deployed or
Rthe vehicle decelerates rapidly from a speed
of above 45 mph (70 km/h) and comes to a
standstill
The hazard warning lamps switch off automati-
cally if the vehicle reaches a speed of above
6 mph (10 km/h) again after a full brake appli-
cation.
iThe hazard warning lamps still operate if the
ignition is switched off.
Cornering light function
The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. The cornering light function can only be activated when the
low-beam headlamps are switched on.
Active:
Rif you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
Rif you are driving at speeds between 25 mph
(40 km/h) and 45 mph (70 km/h) and turn
the steering wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after no
more than three minutes.
Cornering light function with traffic circle
function:
The cornering light function is activated on both
sides before entering a traffic circle through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the traffic circle. In this way, pedestrians
crossing the road, for example, are illuminated
by your vehicle in good time.
Active light function
The active light function is a system that moves
the headlamps according to the steering move-
ments of the front wheels. In this way, relevant
areas remain illuminated while driving. This
allows you to recognize pedestrians, cyclists
and animals sooner.
Active: when the lights are switched on.
Vehicles with Lane Keeping Assist: the active
light function evaluates the course of the lane in
which you are driving and pre-emptively con-
trols the active light function.
Adaptive Highbeam Assist
General notes
You can use this function to set the headlamps
to change between low beam and high beam
automatically. The system recognizes vehicles
with their lights on, either approaching from the
opposite direction or traveling in front of your
vehicle, and consequently switches the head-
lamps from high beam to low beam.
The system automatically adapts the low-beam
headlamp range depending on the distance to
the other vehicle. Once the system no longer
