The key centrally locks/unlocks:
R the doors
R the tailgate
R the fuel filler flap G
Risk of accident
If children are left unsupervised in the vehicle,
they could:
R open a door from the inside at any time,
even if it has been locked
R start the vehicle using a key which has been
left in the vehicle
R release the parking brake
They could thereby endanger themselves and
others. Never leave children unsupervised in
the vehicle. Always take the key with you
when leaving the vehicle, even if you are only
leaving it for a short time. :

; F To open/close the tailgate*
= Emergency key element
? % To unlock the vehicle
A Battery check lamp
When unlocking, the turn signals flash once.
When locking, they flash three times.
When it is dark, the surround lighting also
comes on if it is activated in the on-board
computer. The vehicle relocks automatically if you do not
open a door or the tailgate within 40 seconds
of unlocking the vehicle.
KEYLESS GO* You can start, lock or unlock the vehicle using
the KEYLESS GO key. To do this, you only
need carry the 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.
The distance to the door handle from which
you wish to lock or unlock the vehicle must
not be greater than 1 m.
When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid key
is in the vehicle by periodically establishing
radio contact. X
To unlock the vehicle: touch the inner
surface of the door handle.
X To lock the vehicle: press locking but-
ton :.
If you pull on the handle of the tailgate, only
the luggage compartment of the vehicle is
unlocked.
i If the vehicle has been parked for a long
time, you must pull the door handle to acti-
vate KEYLESS GO. 58

laden or towing a trailer, you must select shift
range 1,2or 3in good time. By doing so, you
will make use of the braking effect of the
engine, which relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. G
Risk of accident
The brake pedal is retracted when Distronic
brakes. Do not restrict the movement of the
pedal in any way.
R Do not put any objects in the footwell.
R Ensure that floor mats and carpets are fixed
securely.
R Do not place your foot under the brake
pedal as it could become trapped.
You could otherwise cause an accident and
injure yourself and others. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Distronic is only an aid designed to assist
driving. The driver is fully responsible for the
vehicle's distance from other vehicles, the
vehicle's speed and for braking in good time.
Distronic does not react to:
R pedestrians
R stationary obstacles on the road, e.g. sta-
tionary or parked vehicles
R oncoming and crossing traffic
Distronic may not detect narrow vehicles driv-
ing in front, e.g. motorcycles, or vehicles driv-
ing on a different line. Therefore, always pay
attention to traffic conditions even when Dis-
tronic is activated. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
If a slower-moving vehicle is detected in front,
Distronic causes your vehicle to brake and maintain the preset distance to the vehicle in
front that you have set. G
Risk of accident
Distronic cannot take account of road and
traffic conditions. Deactivate, or do not acti-
vate, Distronic if it does not detect the vehicle
in front, or if it no longer detects it. This is
especially the case:
R before corners
R in filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where the
lanes are diverted, e.g. at motorway/road-
way construction sites
Otherwise, Distronic maintains the current
speed or accelerates to the set speed.
Distronic cannot take account of weather
conditions. Deactivate, or do not activate,
Distronic:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when Distronic is activated. Otherwise,
you may fail to recognise dangers in time,
cause an accident and injure yourself and oth-
ers.
If no car is driving in front of you, Distronic
works like cruise control in the speed range
between 30 km/h and 200 km/h. If a vehicle
is driving in front of you, Distronic Plus works
in the speed range between 0 km/h and
200 km/h.
Do not use Distronic while driving on roads
with steep gradients. 120

If one or more indicator lamps
=are on:
X Turn the selector wheel anti-clockwise ;
until all indicator lamps =that are lit start
to flash.
The vehicle is lowered to highway level. As
soon as the next lowest level is reached,
the indicator lamp stops flashing and goes
out.
While the adjustment is taking place, a mes-
sage appears in the multi-function display,
e.g.: If you press the
WorX button on the
multi-function steering wheel, the messages
will disappear.
Once highway level has been reached, all indi-
cator lamps =go out. You will see a message
in the multi-function display, for example: If you have not previously selected the off-
road menu (Y
page 102) in the on-board com-
puter, the message disappears after about
five seconds.
The vehicle automatically selects highway
level if you are driving at a speed above
115 km/h or if you drive at between
100 km/h and 115 km/h for around 20 sec-
onds. Depending on the ADS basic setting
(Y page 129), the vehicle is lowered to high-
speed level at high speeds. PARKTRONIC*
G
Risk of accident
PARKTRONIC is only an aid and may not
detect all obstacles. It is not a substitute for
attentive driving.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid
using ultrasound. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R release the parking brake
R shift the automatic transmission to D,Ror
N
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper. :
Example: sensors in the front bumper,

Range of the sensors
The sensors must be free of dirt, ice and
slush; otherwise, they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them
(Y page 203). Side view

!
When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. PARK-
TRONIC does not detect such objects when
they are in the immediate vicinity of the vehicle. You could damage the vehicle or
the objects.
Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill could cause PARK-
TRONIC to malfunction.
Minimum distance Centre Approximately 20 cm
Corners Approximately 15 cm
If there is an obstacle within this range, all
warning displays light up and a tone sounds.
If the distance falls below the minimum clear-
ance, it may no longer be shown.
Warning displays The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is located
on the dashboard above the centre air vents.
The warning display for the rear area is in the
roof lamp in the rear compartment. Warning display for front area
:
Left-hand side of the vehicle
; Right-hand side of the vehicle
= Indicator segments
The warning display for each side of the vehi-
cle is divided into five yellow and two red seg-
ments. PARKTRONIC is operational if yellow

Care
Care and cleaning products
Regular care of your vehicle is a condition for
retaining the quality in the long term.
Use only care products and cleaning agents
recommended and approved by Mercedes-
Benz.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
and do not scrub.
Do not touch the surfaces and protective
films with hard objects, e.g. rings or ice
scrapers. You could otherwise scratch or
damage the surfaces and protective film. H
Environmental note
Dispose of empty packaging, cleaning cloths
and polishing wads in an environmentally
responsible manner.
! Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature. Exterior care
Automatic car wash G
Risk of accident
The efficiency of the brakes is reduced after
using an automatic car wash. This could cause
an accident. For this reason, following a car
wash, drive with particular care until the
brakes are dry. You can wash the vehicle in an automatic car
wash from the beginning.
!
Do not wash vehicles with an exterior
spare wheel bracket* in an automatic car
wash.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise a risk of dam-
age to the exterior mirrors.
! When washing your vehicle in a tow-
through car wash, make sure that the auto-
matic transmission is in position N, other-
wise the vehicle could be damaged.
R Vehicles with a key:
Do not remove the key from the ignition
lock. Do not open the driver's or front-
passenger door when the engine is
switched off, as this automatically shifts
the automatic transmission to park posi-
tion Pand locks the wheels, unless you
have previously shifted the automatic
transmission to N.
R Vehicles with KEYLESS GO*:
Do not open the driver's or front-
passenger door when the engine is
switched off, as this shifts the automatic
transmission to park position Pand locks
the wheels.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is fully turned off and that the wind-
screen wiper switch is set to 0. Otherwise,
the rain/light sensor may be activated, trig-
gering unintended wiper movements. This
could cause damage to the vehicle.
After using an automatic car wash, wipe off
wax and drying agents from the windscreen
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windscreen. Care
