Intermittent wiping
The intermittent wiping interval is depen-
dent on the wetness of the windshield. 
Turn the combination switch in direc-
tion of arrow 2 to positionI.
After the initial wipe, pauses between
wipes are controlled by the rain sensor.Single wipe

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

Press 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 257).
!
Do not leave windshield wipers on an
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.
!
If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical effects
may cause the windshield wipers to wipe in an
undesired fashion. This could then damage the
windshield wiper blades or scratch the windows.
You should therefore switch off the windshield
wipers when weather conditions are dry.
i
Intermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or out
of the vehicle from being sprayed.
Intermittent wiping will be continued when


all doors are closed and the gear selector
lever is in drive positionD or reverse gearR
or


the wiper setting is changed using the com-
bination switch
i
To prevent smears on the windshield or
noisy/chattering wiper blades, wipe with wind-
shield washer fluid every now and then even
when it is raining.

Although independent systems, their
protective functions work in conjunction
with each other.The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of malfunctions. The
1indicator lamp in the instrument
cluster comes on when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the 1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the 1indicator lamp:


fails to go out after approximately
4 seconds after the engine was started


does not come on at all


comes on after the engine was started
or while driving

hints” section (

66 Safety and SecurityOccupant safetyThe air bags will not deploy in impacts
which do not exceed the system’s
deployment thresholds. You will then be
protected by the fastened seat belts.The passenger air bag will only be de-
ployed if:


the system, based on the OCS weight
sensor readings, senses that the pas-
senger seat is occupied


the PASSENGER AIR BAG OFF indicator
lamp in the lower part of the center
console is not lit (
page 70)


the impact exceeds a preset
deployment thresholdKnee air bags
1Knee air bag, driver’s side
2Knee air bag, passenger side
The knee air bags are located on the lower
instrument panel. They are designed to op-
erate together with the front air bags in
certain frontal impacts exceeding a preset
threshold. The knee air bags operate best
in conjunction with a properly positioned
and fastened seat belts and when the foot-
well is kept clear of objects.
i
The front air bags in this vehicle have been
designed to inflate in two stages. This allows
the air bag to have different rates of inflation that
are based on the rate of relevant vehicle deceler-
ation as assessed by the air bag control unit.
On the passenger side, the front air bag
deployment is additionally influenced by the
passenger’s weight category as identified by the
Occupant Classification System (OCS)
(
page 67).
The lighter the passenger side occupant, the
higher the vehicle deceleration rate required for
the second stage inflation of the air bag.

67 Safety and Security
Occupant safety
Head-thorax air bags
1Head-thorax air bag
The head-thorax air bags are deployed:

in side impacts exceeding a preset de-
ployment threshold


on the impacted side of the vehicle


independently of the front air bags
The head-thorax air bags are not deployed
in side impacts which do not exceed the
system’s deployment threshold.
Occupant Classification System
The O
ccupant C
lassification S
ystem (OCS)
automatically turns the passenger front air
bag and passenger-side knee air bag on or
off based on the classified occupant
weight category determined by weight
sensor readings from the passenger seat.
Occupants must sit properly belted in a
position that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by
leaning on armrests), the OCS may not be
able to properly approximate the
occupant’s weight category. Both driver and the passenger should
always use the PASSENGER AIR BAG OFF
indicator lamp (
page 70) as an indica-
tion of whether or not the passenger is
properly positioned.
i
The system does not deactivate the
head-thorax air bag and the emergency tension-
ing device.
i
If the seat needs to be serviced in any way,
take the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.

68 Safety and SecurityOccupant safetyWarning!
G
If the PASSENGER AIR BAG OFF indicator
lamp illuminates when an adult or someone
larger than a small individual is in the pas-
senger seat, have the passenger re-position
himself or herself in the seat until the
PASSENGER AIR BAG OFF indicator lamp
goes out.
For information on air bag display
messages, see (
page 324).
In the event of a collision, the air bag control
unit will not allow passenger front air bag or
passenger knee air bag deployment when
the OCS classified the passenger seat occu-
pant as being up to or less than the weight
of a typical 12-month-old child in a standard
child restraint or if the passenger seat is
sensed as being empty.
When the OCS senses that the passenger
seat occupant is classified as being up to or
less than the weight of a typical
12-month-old child in a standard child
restraint, the PASSENGER AIR BAG OFF indi-
cator lamp will illuminate when the engine is
started and remain illuminated, indicating
that the passenger front air bag and passen-
ger knee air bag are deactivated.
When the OCS senses that the passenger
seat is classified as being empty, the
PASSENGER AIR BAG OFF indicator lamp
will illuminate when the engine is started
and remain illuminated, indicating that the
passenger front air bag and the passenger
knee air bag are deactivated.
When the OCS senses that the passenger
seat occupant is classified as being heavier
than the weight of a typical 12-month-old
child seated in a standard child restraint or
as being a small individual (such as a young
teenager or a small adult), the PASSENGER
AIR BAG OFF indicator lamp will illuminate
for approximately 6 seconds when the
engine is started and then, depending on
occupant weight sensor readings from the
seat, remain illuminated or go out. With the
PASSENGER AIR BAG OFF indicator lamp
illuminated, the passenger front air bag and
the passenger knee air bag are deactivated.
With the PASSENGER AIR BAG OFF indicator
lamp out, the passenger front air bag and
the passenger knee air bag are activated.
When the OCS senses that the passenger
seat occupant is classified as an adult or
someone larger than a small individual, the
PASSENGER AIR BAG OFF indicator lamp
will illuminate for approximately 6 seconds
when the engine is started and then go out,
indicating that the passenger front air bag

116 Controls in detailInstrument clusterTachometer
The red marking on the tachometer
(page 29) denotes excessive engine
speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
The outside temperature is displayed in
the left or right multifunction display
(page 117), depending on the setting for
the standard display (
page 132). The 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.
!
Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
