Parktronic is automatically activated
when you turn the key to position 2in the
ignition lock.
Trailer towing* Parktronic is deactivated for the rear area
when you establish an electrical connection
between your vehicle and a trailer.
! Remove the detachable trailer coupling if
it is no longer required. Parktronic meas-
ures the minimum detection range to an
obstacle from the bumper, not the ball cou-
pling. Active parking assist*
Active parking assist is an electronic parking
aid with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
A suitable parking space is indicated by the
parking symbol. Active steering intervention
can assist you during parking. You may also
use Parktronic (Y page 119). When Parktronic
is deactivated, active parking assist is also
unavailable. G
Risk of accident
Active parking assist is merely an aid and
may sometimes recommend parking
spaces that are not suitable for parking.
These might be, for example, spaces where
parking is prohibited, driveways, unsuitable
surfaces, etc.
Active parking assist measures the parking
space as you drive past it. Any later
changes to the parking space are not taken
into account. This may be the case, for
instance, when the vehicle parked in front
of or behind the space changes its position
or when an obstacle is moved into the park-
ing space.
Active parking assist does not relieve you
of the responsibility of paying attention. If
you rely solely on Active parking assist, you
could cause an accident and injure yourself
and others.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. G
Risk of accident
Objects located above the height range of
Active parking assist will not be detected when the parking space is measured. These
are not taken into account when the park-
ing procedure is calculated, e. g. overhang-
ing loads, tail sections or loading ramps of
goods vehicles. In some circumstances,
Active parking assist may therefore guide
you into the parking space too early. This
may lead to a collision. For this reason, you
should avoid using Active parking assist in
such situations.
G
Risk of accident
The front of the vehicle will veer out in the
direction of the oncoming traffic during the
parking operation. In some cases the vehi-
cle will also take you onto sections of the
oncoming lane during the parking proce-
dure.
You are responsible for safety at all times
and must pay attention to any road users
approaching or passing. Stop the vehicle if
necessary or cancel the Active parking
assist parking procedure. G
Risk of injury
Make sure that no persons or animals are
in the manoeuvring range. Otherwise, they
could be injured. Controls

A warning tone sounds. the multi-function
display shows the message: Park Assist
cancelled .
When active parking assist is cancelled, you
must steer again yourself.
Trailer towing* For vehicles with a trailer coupling, the mini-
mum length for parking spaces is slightly
increased.
If you have attached a trailer to your vehicle,
you should not use active parking assist.
Once the electrical connection is established
between your vehicle and the trailer, active
parking assist is no longer available. Park-
tronic is deactivated for the rear area. ECO start/stop function*
The ECO start/stop function automatically
switches off the engine as soon as you stop
the vehicle and restarts the engine as soon as
you prepare to pull away again. Each time the
engine is started using the key, the ECO
start/stop function is activated.

pants could be injured by objects being
thrown around if you:
R brake sharply
R change direction suddenly
R are involved in an accident
Only use the cup holders for containers of
a suitable size and which have lids. Other-
wise, the drinks could spill.
Cup holders should not be used for hot
drinks. Otherwise, you may scald yourself. Cup holder in the centre console 1

! Do not fold the armrest up unless the cup
holder is closed. Otherwise, the cup holder
could be damaged. Roof rack system* and ski rack*
G
Risk of accident
An incorrectly secured roof rack, ski rack
or load could work loose from the vehicle
and thereby cause an accident. Follow the
roof rack/ski rack manufacturers' installa-
tion instructions and special instructions
for use.
The roof load raises the vehicle's centre of
gravity, thereby affecting vehicle handling.
You must observe the maximum roof load
of 75 kg. Always adapt your driving style to
the prevailing road, traffic and weather con-
ditions and drive with particular care if the
roof is laden.
! Mercedes-Benz recommends that you
only use roof rack systems which have
been tested and approved for Mercedes- Controls

age to the vehicle.
Position the load on the roof rack in such a
way that the vehicle will not sustain dam-
age even when it is in motion.
Depending on the vehicle's equipment,
make sure that you can:
R open the panorama louvred sliding sun-
roof* fully
R open the tailgate fully 1
Covers
X Fold covers 1upwards.
X Only secure the roof rack to the anchorage
points under covers 1. Observe the manufacturer's installation
instructions. Luggage net
G
Risk of injury
Only place lightweight items in the luggage
net. Do not use it to transport heavy, bulky,
sharp-edged or fragile objects. In the event
of an accident, the luggage net will not
secure the transported goods. Loading guidelines
G
Risk of injury
Secure and position the load as described
in the loading guidelines.
Otherwise, vehicle occupants could
be injured by the load being thrown around
in the event of sharp braking, a sudden
change in direction or an accident. This also
applies to seats which have been removed.
You will find further information in the
"Securing a load" 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
Keep the tailgate closed when the engine is
running. Otherwise, you could be poisoned
by exhaust fumes entering the vehicle.
The handling characteristics of a laden vehi-
cle depend on the distribution of the load
within the vehicle. You should therefore load
your vehicle as shown in the illustrations. Observe the following notes when transport-
ing a load:
R
When transporting a load, 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 down in the luggage compartment as
possible.
R The load must not protrude above the
upper edge of the backrests. Controls

R
Always place the load against the rear seat
backrests or the seat cushions if these
have been folded forwards.
R The maximum load capacity of the stowage
well under the luggage compartment floor
is 25 kg.
R Always place the load behind unoccupied
seats if possible.
R Secure the load with sufficiently strong and
wear-resistant load restraints. Pad sharp
edges for protection.
i Load restraints are available at any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre. R
If the rear seats are not occupied, insert the
belt tongue on the outer seat belts into the
buckle of the opposite seat belt. This
increases the restraining effect of the rear
seat backrests.
! Do not position the load on one part of the
folding luggage compartment floor only.
The maximum load capacity of the folding
luggage compartment floor is 100 kg.
Spread the weight evenly to avoid damag-
ing the luggage compartment floor. If nec-
essary, place a solid board under the load.
Please note that the load on the luggage compartment floor will be increased when
the load is lashed down.

Loading sill protector
! Do not sit down or stand on the loading
sill when loading. Never place any heavy
loads on the loading sill. This can cause
serious and permanent damage to the
bumper.
The loading sill protector serves only to
protect the painted surface. Controls

Lashing eyelets G
Risk of injury
Distribute the load on the lashing eyelets
evenly.
Otherwise, vehicle occupants could be
injured by objects being thrown around if
you:
R brake sharply
R change direction suddenly
R are involved in an accident
Please observe the loading guidelines.
Observe the following points or guidelines
when securing loads:
R Secure the load using the lashing eyelets.
R Do not use elastic straps or nets to secure
a load, as these are only intended as an
anti-slip protection for light loads.
R Do not route lashing materials across sharp
edges or corners.
R Pad sharp edges for protection. Securing loads in the luggage compart-
ment

Lashing eyelets
X Secure the load using lashing eyelets 1or
the mounting cups for the seats, if the seats
have been removed.
Securing a load when the seats have been
removed X
Guide the load restraints in a cross pattern
over the load, as shown in the illustration.
X Secure the load using the lashing eyelets
or the mounting cups on the seats. G
Risk of injury
Always stow the load so that it does not
interfere with driving the vehicle.
Avoid obstructing the driver's line-of-sight.
The load must not protrude above the upper
edge of the door trim if the front-passenger
seat has been removed.
Pad sharp edges for protection. This will
reduce the risk of lacerations and prevent
the load restraints from wearing.
Observe the following notes:
R The load must not protrude above the
upper edge of the door trim.
R Long loads must only be placed low down
and towards the front of the front-
passenger footwell.
! Load restraints must not be fastened to
the front right-hand mounting cup. Other-
wise, the contact switch for the front-
passenger seat could be damaged. Controls
