tions. Exterior mirrors
G
Risk of accident
The exterior mirrors reduce the size of the
image. Objects are actually closer than
they appear. You could misjudge the dis-
tance from vehicles driving behind and
cause an accident, e.g. when changing
lane. For this reason, make sure of the
actual distance from the vehicle driving
behind by glancing over your shoulder.
The convex exterior mirrors provide a larger
field of vision.
At low outside temperatures the exterior mir-
rors are heated automatically.

ror is set to a position which provides you
with a good overview of traffic conditions.
You will find further information in the "Stor-
ing settings" section (Y page 70). Automatic anti-dazzle rear view mir-
ror*
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
dazzle mode if the ignition is switched on and
incident light from headlamps strikes the sen-
sor in the mirror.
The mirrors do not go into anti-dazzle mode if
reverse gear is engaged or the interior lighting
is switched on. G
Risk of accident
If the incident light from headlamps cannot
strike the sensor in the rear-view mirror, for
instance by objects in the vehicle, the mir-
rors' automatic anti-dazzle function will not
operate.
Incident light could then dazzle you. This
may prevent you from observing the traffic
conditions, thereby causing an accident. In
this case, adjust the rear-view mirror man-
ually. Controls

Driving sys
tems 118 Ultrasonic reversing aid* (Station
wagon) G
Risk of accident
The ultrasonic reversing aid 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
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.
The ultrasonic reversing aid is an electronic
parking aid. It indicates visually and audibly
the distance between the rear area of your
vehicle and an object.
The ultrasonic reversing aid is activated auto-
matically when you switch on the ignition and
engage the reverse gear.
The ultrasonic reversing aid monitors the rear
bumper and rear area of your vehicle using
four sensors. 1
Sensors
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. Side view, example: short-wheelbase station
wagon

!
When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. The ultra-
sonic reversing aid 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 the ultra-
sonic reversing aid to malfunction.
Minimum distance Centre Approximately 30 cm
Corners Approximately 30 cm
If there is an obstacle within this range, all
warning displays flash and a warning tone
sounds. If the distance falls below the mini-
mum clearance, it may no longer be shown.
Warning displays
The warning display shows the distance
between the sensors and the obstacle.
Station wagon: the warning display is in the
rear next to the tailgate.
Cabriolet: the warning display is on the front-
passenger side at the top on the roll bar. Example: station wagon
The warning display is divided into four yellow
and two red segments. If you hear a warning
tone and all segments light up briefly, the
ultrasonic reversing aid is operational.
One or more segments light up as the vehicle
approaches an obstacle, depending on the
vehicle's distance to the obstacle.
From the:
R
fourth segment you will hear an intermit-
tent warning tone
R fifth segment you will hear a faster inter-
mittent warning tone
R sixth segment you will hear a very fast inter-
mittent warning tone. You have reached
the minimum distance. Trailer towing The ultrasonic reversing aid is deactivated
when you connect the trailer to your vehicle
electrically.
!
The ultrasonic reversing aid measures
the minimum detection range to an obsta-
cle from the bumper, not the ball coupling
or the spare wheel. Reversing camera* (Station wagon)
The reversing camera is an optical aid. It
shows the area behind your vehicle in the
COMAND APS display. G
Risk of injury
Make sure that no persons or animals are
in the manoeuvring range. Otherwise, they
could be injured.
The reversing camera is in the tailgate above
the rear window wiper. Controls

Care
183H
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 beginning. !
Do not use a touch-free automatic car
wash that uses chemical agents to wash
the vehicle.
Preferably use automatic car washes without
brushes.
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.
! 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. The rain
sensor may otherwise be activated, trig-
gering unintended wiper movements. This
could cause damage to the vehicle.
After using an automatic car wash, wipe any
wax and drying agents off the windscreen and
the wiper blades. This will prevent smears and
reduce wiping noises caused by residue on
the windscreen. High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with cir-
cular-jet nozzles (dirt grinders) to clean
your vehicle or ― especially ― the tyres.
Otherwise, you could damage the tyres and
cause an accident.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door joint
R electrical components
R battery
R connectors
R lights
R seals
Damaged seals or electrical components
can lead to failures or leaks. Operation

Troubleshooting
223Problem Possible cause/consequence Suggested solutions
You hear a warning signal when
reversing. The ultrasonic reversing aid sen-
sors are dirty or there is interfer-
ence. X
Clean the ultrasonic reversing aid sensors (Y page 186).
X Switch the ignition back on. The problem ma
y be caused by an
external source of radio or ultra-
sound waves. The ultrasonic
reversing aid is switched off. X
See if ultrasonic reversing aid functions in a different location. You hear a warning tone when
reversing or you do not hear a
warning tone and none of the seg-
ments light up. The ultrasonic reversing aid has
malfunctioned and has switched
itself off. X
Have the ultrasonic reversing aid checked at a qualified specialist
workshop as soon as possible. Headlamps and turn signals
Problem Possible cause/consequence Suggested solutions

Vehicle electronics
260 Vehicle electronics
Tampering
with the engine electron-
ics G
Risk of accident
Only have work on the engine electronics
and related components carried out at a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The vehicle's roadworthiness could other-
wise be affected.
! Only have work done on the engine elec-
tronics and its associated parts, such as
control units, sensors and connector leads,
carried out at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service
Centre. Otherwise, vehicle components
may wear more quickly and your vehicle's
warranty and operating permit may be inva-
lidated. Retrofitting electrical and electronic
equipment
Electrical and electronic equipment can jeop-
ardise the operating safety of your vehicle. If
equipment of this kind is retrofitted, it must
be type-approved and bear the emark. The
e mark may be obtained from the equipment
manufacturer or an authorised testing centre.
! Damage or consequential damage arising
from fitting equipment not approved by
Mercedes-Benz is not covered by the
Mercedes-Benz warranty.
If you wish to install two-way radios in the
vehicle, you must obtain formal approval.
Mercedes-Benz approves the installation of
two-way radios if such equipment is installed
professionally and a low-reflection exterior
aerial is used.
The transmission output of the two-way radio
must not exceed the maximum transmission
outputs listed. G
Risk of accident
Two-way radios may interfere with the vehi-
cle electronics and thereby jeopardise the
operational safety of the vehicle and your
own safety if: R
they do not have an exterior aerial
R the exterior aerial is not a low-reflection
aerial
R the exterior aerial has been fitted incor-
rectly G
Risk of injury
Excessive electromagnetic radiation may
also cause damage to your health and the
health of others. Using an exterior aerial
takes into account current scientific dis-
cussions relating to the possible health haz-
ards that may result from electromagnetic
fields.
For this reason, only have the exterior aerial
fitted at a qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work
required. Mercedes-Benz recommends
that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
i Mercedes-Benz recommends the use of
an approved exterior aerial. This ensures
optimal reception quality for mobile tele- Technical data
