approx.

6.4 US qt (6.0 l) in vehicles with head-
lamp cleaning system*


3.2 US qt (3.0 l) in vehicles without
headlamp cleaning system

Refill the reservoir with MB Windshield
Washer Concentrate and water (or con-
centrate and commercially available
premixed windshield washer sol-
vent/antifreeze, depending on ambient
temperatures).Windshield and headlamp washer fluid
mixing ratio
For temperatures above freezing use
MB Windshield Washer Concentrate “S”
and water:


1 part “S” to 100 parts water
[40 ml “S” to 1 gallon (4 liters) water]
For temperatures below freezing use
MB Windshield Washer Concentrate “S”
and commercially available premixed
windshield washer solvent/antifreeze:


1 part “S” to 100 parts solvent
[40 ml “S” to 1 gallon (4 liters) solvent].
Warning!

Consumer information
The following text is published as required
of all manufacturers of passenger cars un-
der Title 49, Code of U.S. Federal Regula-
tions, Part 575 pursuant to the “National
Traffic and Motor Vehicle Safety Act of
1966”.Uniform tire quality grading
Quality grades can be found, where appli-
cable, on the tire sidewall between tread
shoulder and maximum section width. For
example:
All passenger car tires must conform to
federal safety requirements in addition to
these grades.Tread wear
The tread wear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
a nd one-ha lf (1½ ) tim es as wel l on the gov-
ernment course as a tire graded 100. The
relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly
from the norm due to variations in driving
habits, service practices and differences in
road characteristics and climate.Traction
The traction grades, from highest to lowest
are AA, A, B, and C. Those grades repre-
sent the tire’s ability to stop on wet pave-
ment as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.Tread wear

Warning!
G
The traction grade assigned to this tire is
based on straightahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.

326 Technical dataConsumer informationTemperature
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and ex-
cessive temperature can lead to sudden
tire failure. Grade C corresponds to a level
of performance which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B
and A represent higher levels of perfor-
mance on the laboratory test wheel than
the minimum required by law.
Warning!
G
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underin-
flation, or excessive loading, either sepa-
rately or in combination, can cause
excessive heat build-up and possible tire
failure.

327 Technical terms
ABS
(A
ntilock B
rake S
ystem)
Prevents the wheels from locking up
during braking so that the vehicle can
continue to be steered.
Alignment bolt
Metal pin with thread. The centering
pin is an aid used when changing a tire
to align the wheel with the wheel hub.
BabySmart
TM
airbag deactivation
system
This system detects if a special system
compatible child restraint seat is in-
stalled on the front passenger seat. The
system will automatically deactivate
the passenger front airbag when such a
seat is properly installed (indicator

in the center console lights
up). See your authorized
Mercedes-Benz Center for availability.BabySmart
TM
compatible child seats
Special restraint system for children.
The sensor system for the passenger
seat prevents deployment of the pas-
senger side airbag if a BabySmart
TM
compatible child seat is installed.
BAS
(B
rake A
ssist S
ystem)
System for potentially reducing braking
distances in emergency braking situa-
tions. The system is activated when it
senses an emergency based on how
fast the brake is applied.
Bi-Xenon headlamps*
Headlamps which use an electric arc as
the light source and produce a more in-
tense light than filament headlamps.
Bi-Xenon headlamps produce low
beam and high beam.CAC
(C
ustomer A

ter, which can help you with any ques-
tions about your vehicle and provide
assistance in the event of a break-
down.

hicle functions such as door locking or
windshield wiping.

GPS*
(G
lobal P
ositioning S
ystem)

geographic location information to and
from vehicles equipped with special re-
ceivers. Employs CD digital maps for
navigation.
Instrument cluster
The displays and indicator/warning
lamps in the driver’s field of vision, in-
cluding the tachometer, speedometer
and fuel gauge.
Kickdown
Depressing the accelerator past the
point of resistance shifts the transmis-
sion down to the lowest possible gear.
This very quickly accelerates the vehi-
cle and should not be used for normal
acceleration needs.
Lock button
Button on the door which indicates
whether the door is locked or un-
locked. Pushing the lock button down
on an individual door from inside will
lock that door.Memory function*
Used to store three individual seat,
steering wheel and mirror positions for
each key.
Menu
The control system displays are ar-
ranged in menus. Each menu contains
a number of commands for particular
systems. In the Audio menu, for exam-
ple, you will find the commands
Select
radio station
or Operate CD player
.
Using commands you can directly
change the settings for your vehicle.
MON
(M
otor O
ctane N
umber)
The Motor Octane Number for gasoline
as determined by a standardized meth-
od. It is an indication of a gasoline's
ability to resist undesired detonation
(knocking). The average of both the
MON (Motor Octane Number) and
->RON (Research Octane Number) is
posted at the pump, also known as AN-
TI-KNOCK INDEX.Multifunction display
Display field in the instrument cluster
used to present information provided
by the control system.
Multifunction steering wheel
Steering wheel with buttons for operat-
ing the control system.
