Switching the windshield wiper
on/off
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
! If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windshield becoming dirty in dry weather conditions,
the windshield wipers may be activated
inadvertently. This could then damage the
windshield wiper blades or scratch the wind-
shield.
For this reason, you should always switch
off the windshield wipers in dry weather. 1

X Turn the í wiper switch to the corre-

In the Ä or Å
positions, 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 to
precipitation than in the Ä position, caus-
ing the windshield wipers to wipe more fre-
quently.
The windshield will no longer be wiped prop-
erly if the wiper blades are worn. This may pre-
vent you from observing the traffic conditions.
Information on replacing the wiper blades can
be found under "Replacing wiper blades"

it will go to 1 or press and hold 4.
When you release the è switch, the rear
window wiper continues to wipe for about
another five seconds. The rear window
wiper then wipes according to the original
position 2 or 3.
The rear window wiper switches on automati-
cally if you engage reverse gear and the wind-
shield wipers are on.
If the vehicle is stationary and you open the
tailgate or rear-end door, the rear window
wiper will stop automatically. The rear window
wiper will only resume wiping again when the
tailgate and rear-end door are closed and you
pull away again.
The rear window will no longer be wiped prop-
erly if the wiper blade is worn. This may pre-
vent you from observing the traffic conditions.
Information on replacing the wiper blade can be found under "Replacing wiper blades"

Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you
could be trapped by the wiper arm. There is
a risk of injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! Never open the hood/tailgate or rear
doors if a windshield wiper arm has been
folded away from the windshield/rear win-
dow.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield/rear
window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield/rear
window, the windshield/rear window may
be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
! Only hold the wiper blade by the wiper
arm. You could otherwise damage the wiper
rubber.
Wiper blades are wear parts. The windshield
will no longer be wiped properly if the wiper
blades are worn. This may prevent you from
observing the traffic conditions.
Please observe the service indicator after
changing the wiper blades of the windshield
wiper.
Service indicator Replacement wiper blades for the windshield
wiper have a service indicator on the tip of the
wiper blade.
Depending on the amount of use, the service
indicator will change color from black to yel-
low.110

Introduction
Important safety notes G
WARNING
If the instrument cluster has failed or malfunctioned, you may not recognize function restric-
tions in systems relevant to safety. The operating safety of your vehicle may be impaired.
There is a risk of an accident.
Drive on carefully. Have the vehicle checked at a qualified specialist workshop immediately.
The on-board computer only shows messages or warnings from certain systems in the instru-
ment cluster display. You should therefore make sure your vehicle is operating safely at all
times. If the operating safety of your vehicle is impaired, stop the vehicle as soon as possible,
paying attention to road and traffic conditions. Then consult a qualified specialist workshop.
Display messages with graphic symbols are simplified in the Operator's Manual and may differ
from the symbols in the display. The display shows high-priority display messages in red. A warn-
ing tone sounds with certain display messages.
Please respond in accordance with the display messages and follow the additional notes in this
Operator's Manual.
You can hide low-priority display messages using the a or % steering wheel button. The
display messages are then stored in the message memory. Rectify the cause of a display mes-
sage as soon as possible.
High-priority display messages cannot be hidden. These messages will continue to be shown in
the display until their cause has been eliminated.
Message memory The on-board computer stores certain display messages in the
message memory. You can call

General notes
When switching on the ignition, some systems carry out a self-test. Some indicator and warning
lamps may temporarily turn on or start to flash. This is not an indication of any problem. Only
when these indicator and warning lights turn on or start flashing after the engine has started or
during the journey has a malfunction occurred. Indicator and warning lamps in the instrument cluster

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.

Hood
Important safety notes G
WARNING
If the hood is unlatched, it may open up
when the vehicle is in motion and block your
view. There is a risk of an accident.
Never unlatch the hood while driving. Before
every trip, ensure that the hood is locked. G
WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department. G
WARNING
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off.
There is a risk of injury. If you need to do any work inside the engine
compartment:
R switch off the ignition
R never reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
R remove jewelry and watches
R keep items of clothing and hair, for exam-
ple, away from moving parts G
WARNING
The ignition system operates with a high
voltage. If you touch the live components,
you could receive an electric shock. There is
an increased risk of injury.
Never touch components of the ignition sys-
tem if:
R the engine is running or being started
R the key is in radio position or drive posi-
tion in the ignition lock
The live components of the ignition system
are, for example:
R ignition coils
R spark plug connectors
R diagnostic sockets G
WARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very
hot. Working in the engine compartment
poses a risk of injury.
Where possible, let the engine cool down
and touch only the components described in
the following.
If you have to carry out work in the engine
compartment, only touch the following compo-
nents:
R hood
R oil dipstick
R engine oil filler neck cap
R washer fluid reservoir cap
R coolant expansion tank cap250
