R if the sensors are dirty or there is poor
visibility, e.g. due to snow, rain or fog.
Distance control may be impaired.
Always pay attention to traffic conditions
even when Distronic is activated. Other-
wise, you may fail to recognise danger in
time, could cause an accident and injure
yourself and others.
If there is no vehicle in front, Distronic oper-
ates in the same way as cruise control. Dis-
tronic functions in the 30 km/h to
180 km/h range. G
Risk of accident
Distronic brakes your vehicle at a maximum
of 2 m/s 2
, depending on its speed. This
corresponds to approximately 20% of your
vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
If Distronic detects a risk of collision with a
vehicle in front, an intermittent warning
tone sounds. In addition, the ldistance
warning lamp in the instrument cluster
lights up. Brake to avoid a collision. Cruise control lever You can operate Distronic and variable
Speedtronic with the cruise control lever.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:

While the adjustment is taking place, a mes-

e.g. : If you press the
æorç button on the
multi-function steering wheel, the messages
will disappear.
Once highway level has been reached, all indi-

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-

Risk of accident
Parktronic is only an aid and may not detect
all obstacles. It is not a substitute for atten-
tive driving.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. You could otherwise endan-
ger 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. It indi-
cates 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. 1
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

!
When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. Parktronic
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 Parktronic
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 trim at the rear. Controls

Care
248 H
Environmental note
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally responsible manner.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces, otherwise you could
damage the paintwork. Vehicle care
! 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.
Automatic car wash You can wash the vehicle in an automatic car
wash from the very start. !
Vehicles with an exterior spare wheel
bracket* must not be washed in an auto-
matic car wash.
! Do not use a touch-free automatic car
wash that uses chemical agents to wash
the vehicle.
Preferably use one without brushes.
If the vehicle is very dirty, prewash 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.
! Make sure that the automatic transmis-
sion is not in position Pwhen washing your
vehicle in an automatic car wash.
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 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 the side windows are com-
pletely closed, the ventilation/heater
blower is fully turned off and the wind-
screen wiper switch is set to 0. The rain
sensor may otherwise be activated, for
instance, leading to inadvertent wiper
sweeps being triggered. This could cause
damage to the vehicle.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen.

(e.g. increased formation of wrinkles) to
certain environmental influences (such as
high humidity, intense heat).
Note that regular care is essential to ensure
that the quality (both appearance and com-
fort) of the covers is retained over time.
Cleaning real wood* and trim strips X
Moisten a clean lint-free cloth with water.
X Clean the wooden trim.
X If particularly dirty, use a mild detergent.
! Do not use cleaning agents containing
solvents because these can damage the
wooden trim.
Cleaning the exhaust tail pipes Impurities combined with the effects of road
grit and corrosive environmental factors may
cause flash rust to form on the surface.
Regular care of the exhaust tail pipes will
ensure that their original shine is restored.
! Do not clean exhaust tail pipes with alka-
line-based cleaning agents such as wheel
cleaner.
Use the chrome-cleaning agent recommen-
ded by Mercedes-Benz for cleaning. Infor- mation about chrome-cleaning agents can
be obtained from any Mercedes-Benz
Service Centre.
Cleaning Distronic* 1
Distronic* cover
X Turn the key to position 0(Y page 75) in

X Clean cover 1in the radiator grille with
water, car shampoo and a soft cloth.
! Do not use dry, coarse or hard cloths and
do not scrub. Doing so will scratch or dam-
age the surfaces. Cleaning Parktronic* The sensors are located in the front and rear
bumpers.
