53 Getting started
Driving
Switching on windshield wipers
Turn the combination switch to the
desired position depending on the
intensity of the rain.
0Windshield wipers off
IIntermittent wiping
IINormal wiper speed (goes to
settingI when the car is standing
still)
IIIFast wiper speed (goes to settingI
when the car is standing still)Intermittent wiping

Set the wiper switch to positionI.
Single wipe

Press combination switch briefly in
direction of arrow1.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid

Push combination switch in direction of
arrow1 past the resistance point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system”
(
page 251).
iIntermittent wiping interval is
dependent on wetness of windshield.
After the initial wipe, pauses between
wipes are automatically controlled by
the rain sensor.
!Do not leave windshield wipers in
intermittent setting when the vehicle is
taken to an automatic car wash or
during windshield cleaning. Wipers will
operate in the presence of water
sprayed on the windshield, and wipers
may be damaged as a result.
The switch should not be left in
intermittent setting as the wipers will
wipe the windshield once every time
the engine is started. Dust that
accumulates on the windshield might
scratch the glass and/or damage the
wiper blades when wiping occurs on a
dry windshield.

116 Controls in detailInstrument clusterThe temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. There-
fore, the accuracy of the displayed temper-
ature can only be verified by comparison to
a thermometer placed next the sensor, not
by comparison to external displays, e.g.
bank signs, etc.
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.

179 Controls in detail
Good visibility
Rear view mirrors
For more information on setting the rear
view mirrors, see “Mirrors” (
page 43).
Auto-dimming mirror
The reflection brightness of the interior
rear view mirror will respond automatically
to glare when


the ignition is switched on
and


incoming light from headlamps falls on
the sensor in the interior rear view
mirror.
The rear view mirror will not react if


reverse gearR is engaged


the interior lighting is turned on
Warning!
G
The auto-dimming function does not react if
incoming light is not aimed directly at sen-
sors in the interior rear view mirror.
Glare can endanger you and others.Warning!
G
In the case of an accident liquid electrolyte
may escape from the mirror housing if the
mirror glass breaks.
Electrolyte has an irritating effect. Do not
allow the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state and by applying plenty of
water.Warning!
G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your
interior rear view mirror or glance over your
shoulder before changing lanes.

237 Operation
Driving instructions
Control and operation of radio transmitters
Radio and telephoneTelephones and two-way radios
Radio transmitters, such as a portable
telephone or a citizens band unit should
only be used inside the vehicle if they are
connected to an antenna that is installed
on the outside of the vehicle.
Refer to the radio transmitter operation
instructions regarding use of an external
antenna.
Catalytic converter
Your Mercedes-Benz is equipped with
monolithic-type catalytic converters, an
important element in conjunction with the
oxygen sensors to achieve substantial
control of the pollutants in the exhaust
emissions. Keep your vehicle in proper
operating condition by following our
recommended maintenance instructions
as outlined in your Maintenance Booklet.
Warning!
G
Please do not forget that your primary
responsibility is to drive the vehicle safely.
Only operate the radio or telephone
1 if road,
weather and traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
1Observe all legal requirements.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system,
possibly resulting in an accident and
personal injury.
!To prevent damage to the catalytic
converters, only use premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise excessive unburned fuel
may reach the catalytic converter,
causing it to overheat and potentially
start a fire.

265 Operation
Tires and wheels
Checking tire inflation pressure
electronically
The tire inflation pressure monitor only
functions on wheels that are equipped with
the proper electronic sensors. It monitors
the tire inflation pressure, as selected by
the driver, in all four tires. A warning is is-
sued to alert you to a decrease in pressure
in one or more of the tires.
Tire inflation pressure inquiries are made
using the multifunction display
(page 117). The present inflation pres-
sures are displayed only after a few min-
utes travel time.

Switch on the ignition (
page 40).

Make sure you are viewing the stan-
dard display menu (
page 117).

Press k button until the current in-
flation pressures for each tire appear in
the tachometer display field.
iPossible differences between the read-
ings of a tire inflation pressure gauge of
an air hose, e.g. gas station equipment,
and the vehicle’s control system can
occur. The readings issued by the con-
trol system are more precise.
iYou can select the unit of measure
(bar/psi) used for the tire inflation
pressure by changing the setting in the
control system (
page 136).
Warning!
G
When the tire inflation pressure monitoring
system warning light is lit, one or more of
your tires is significantly under-inflated. You
should stop and check your tires as soon as
possible, and inflate them to the proper tire
inflation pressure as indicated on the vehi-
cle’s tire information placard. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Each tire,
including the spare, should be checked
monthly when cold and set to the recom-
mended tire inflation pressure as specified
in the vehicle placard and owner’s manual.


267 Operation
Tires and wheels

Press the reset button (
page 29).
The following message will appear in
the speedometer display field:
Monitor current tire pressure?


Press æ button.
The following message will appear in
the speedometer display field:Tire pressure displayed
after
driving a few mins.
Reactivate w/
R-button
If you wish to cancel activation:
Press ç button.
If the following message appears in the
speedometer display field:
Reactivate tire press. monit.


Re-start the activation of the tire infla-
tion pressure monitor.
If the following message appears in the
speedometer display field:
Tire pressure

Check tires!


Re-start the activation of the tire infla-
tion pressure monitor.Potential problems associated with
underinflated and overinflated tires
Underinflated tire inflation pressure
Underinflated tires can:


cause excessive and uneven tire wear


adversely affect fuel economy


lead to tire failure from being
overheated


adversely affect handling
characteristics
iIf transporting a deflated road wheel or
additional wheel sensors in the vehicle,
the tire inflation pressure monitor
should not be reactivated until the de-
flated wheel or additional wheel sen-
sors have been removed from the
vehicle. Otherwise the deflated wheel
or additional sensors could confuse the
tire inflation pressure monitor system
and cause it to malfunction.
Warning!
G
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being
overheated.
