Implied warranty
! Follow the instructions in this manual
about the proper operation of your vehicle
as well as about possible vehicle damage.
Damage to your vehicle that arises from
culpable contraventions against these
instructions are not covered either by
Mercedes-Benz implied warranty or by the
New or Used-Vehicle Warranty. Data stored in the vehicle
A wide range of electronic components in
your vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
R the vehicle's operating state
R events
R faults
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
R operating conditions of system compo-
nents, e.g. fluid levels
R the vehicle's status messages and those of
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelera-
tor pedal position
R malfunctions and defects in important sys-
tem components, e.g. lights, brakes
R vehicle reactions and operating conditions
in special driving situations, e.g. airbag
deployment, intervention of stability con-
trol systems
R ambient conditions, e.g. outside tempera-
ture This data is of an exclusively technical nature
and can be used to:
R assist in recognising and rectifying faults
and defects
R analyse vehicle functions, e.g. after an acci-
dent
R optimise vehicle functions
The data cannot be used to trace the vehicle's movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data mem- ory and fault data memory.
Services include, for example:
R repair services
R service processes
R warranty events
R quality assurance
It is read by employees of the service network (including manufacturers) using special diag-
nostic testers. More detailed information is
obtained from it, if required.
After a fault has been rectified, the informa-
tion is deleted from the fault memory or is
continually overwritten.
When operating the vehicle, situations are
conceivable in which this technical data, in
connection with other information (if neces-
sary, under consultation with an authorised
expert), could be traced to a person.
Examples include:
R accident reports
R damage to the vehicle
R witness statements
Further additional functions that have been
contractually agreed upon with the customer
allow certain vehicle data to be conveyed by
the vehicle as well. The additional functions
include, for example, vehicle location in case of an emergency. Introduction
35 Z

The hazard warning lamps switch on auto-
matically if:
R an airbag is deployed or
R the vehicle decelerates rapidly from a
speed of above 70 km/h and comes to a
standstill
The hazard warning lamps switch off auto-
matically if the vehicle reaches a speed of
above 10 km/ha gain after a full brake appli-
cation.
i The hazard warning lamps continue to
operate even if the ignition is switched off. Headlamp cleaning system
The headlamps are cleaned automatically if
the "Wipe with washer fluid" function is oper-
ated five times (Y page 135) while the lights
are on and the engine is running. When you
switch off the ignition, the automatic head-
lamp cleaning system is reset and counting is
resumed from 0. Intelligent Light System
General notes The Intelligent Light System is a system that
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions. It offers advanced functions for improved illu-
mination of the road surface, e.g. depending
on the vehicle speed or weather conditions.
The system includes the active light function, cornering light function, motorway mode and
extended range foglamps. The system is only
active when it is dark.
You can activate or deactivate the "Intelligent Light System" using the on-board computer
(Y page 240). Active light function
The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Active: when the lights are switched on
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 vis-
ibility in tight bends, for example. The corner- ing light function can only be activated when
the dipped-beam headlamps are switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the
steering wheel
R if you are driving at speeds between
40 km/ha nd 70 km/h and turn the steer-
ing wheel Exterior lighting

In the ÄorÅ position, the appropriate
wiping frequency is set automatically accord- ing to the intensity of the rain. In the Å
position, the rain sensor is more sensitive
than in the Äposition, causing the wind-
screen wipers to wipe more frequently.
If the wiper blades are worn, the windscreen
will no longer be wiped properly. This could
prevent you from observing the traffic condi-
tions, thereby causing an accident.
i The vehicle is equipped with the MAGIC
VISION CONTROL wipe/wash system. The
washer fluid is fed through the wiper blades
and when the screen is wiped with washer
fluid î, the water is emitted directly
from the blades. Replacing the wiper blades
Important safety notes G
WARNING
If the windscreen wipers begin to move while
you are changing the wiper blades, you can be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windscreen wipers and
ignition before changing the wiper blades.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.
! Never open the bonnet if a windscreen
wiper arm has been folded away from the
windscreen. Never fold a windscreen wiper arm without
a wiper blade back onto the windscreen.
Hold the windscreen wiper arm firmly when you change the wiper blade. If you release
the windscreen wiper arm without a wiper
blade and it falls onto the windscreen, the
windscreen may be damaged by the force
of the impact.
Mercedes-Benz recommends that you have the wiper blades changed at a qualified
specialist workshop.
! Always position the windscreen wiper
arms vertically before folding them away
from the windscreen. By doing so, you will
avoid damage to the bonnet.

Cleaning the paintwork
!
Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop.
X Remove impurities immediately, where
possible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover
and rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse
off the treated areas afterwards.
X Remove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighter fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
Care and treatment of matt paintwork !
Never polish the vehicle or the light alloy
wheels. Polishing makes the paintwork
shiny.
! The following may cause the paint to
become shiny and thus reduce the matt
effect:
R Vigorous rubbing with unsuitable mate-
rials.
R Frequent use of car washes.
R Washing the vehicle in direct sunlight.
! Never use paint cleaner, buffing or pol-
ishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matt finish leads to considerable sur-
face damage (shiny, spotted areas). Always have paintwork repairs carried out
at a qualified specialist workshop.
! Do not use wash programs with a hot wax
treatment under any circumstances.
Observe these notes if your vehicle has a
clear matt finish. This will help you to avoid
damage to the paintwork due to incorrect
treatment.
These notes also apply to light-alloy wheels
with a clear matt finish.
i The vehicle should preferably be washed
by hand using a soft sponge, car shampoo
and plenty of water.
i Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products. Cleaning vehicle parts
Cleaning the wheels !
Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up.
Cleaning the windows G
WARNING
If the windscreen wipers are set in motion
when cleaning the windscreen or wiper
blades, you could become trapped. There is a danger of injury.
Always switch off the windscreen wipers and
the ignition before cleaning the windscreen orwiper blades. 570
