Windshield washer system and head-lamp cleaning system
Both the windshield washer system and
headlamp cleaning system are supplied
from the windshield washer reservoir.
The windshield washer reservoir has a
capacity of approximately 7.4 US qt (7 l).
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 point, use
MB Windshield Washer Concentrate
“MB SummerFit” and water:


1 part “MB SummerFit” to 100 parts
water
(1.34 fl oz [40 ml] “MB SummerFit” to
1gal [4.0l] water)
For temperatures below freezing point, use
MB Windshield Washer Concentrate
“MB SummerFit” and commercially avail-
able premixed windshield washer
solvent/antifreeze:


1 part “MB SummerFit” to 100 parts
solvent
(1.34 fl oz [40 ml] “MB SummerFit” to
1 gal [4.0 l] solvent)
Warning!
G
Washer solvent/antifreeze is highly flamma-
ble. Do not spill washer solvent/antifreeze
on hot engine parts because it may ignite
and burn. You could be seriously burned.

Control system
The control system is used to call up
vehicle information and to change
component settings. Information and
messages appear in the multifunction
display. The driver uses the buttons on
the multifunction steering wheel to
navigate through the system and to
adjust settings.

Driving convenience system for auto-
matically maintaining the vehicle speed
set by the driver.

Engine number
The number set by the manufacturer
and placed on the cylinder block to
uniquely identify each engine
produced.
Engine oil viscosity
Measure of the internal oil friction (vis-
cosity) at different temperatures. The
higher the temperature the oil can tol-
erate without thinning too much, or the
lower the temperature it can tolerate
without thickening too much, the bet-
ter the viscosity characteristics of the
oil.ESP

can be adapted to specific operating
conditions using the gear selector lever
or the steering wheel gearshift control
buttons.GPS

Head-thorax air bag
Installed in the doors, these air bags
protect occupants during side impact
collisions exceeding a preset thresh-
old. Unlike normal side air bags,
head-thorax air bags are also designed
to provide protection for the head area.

Instrument cluster
The displays and indicator/warning
lamps in the driver’s field of vision, in-
cluding the tachometer, speedometer,
engine temperature and fuel gauge.
Kickdown
Depressing the accelerator past the
point of resistance shifts the transmis-
sion down to the lowest possible. This
very quickly accelerates the vehicle
and should not be used for normal
acceleration needs.

method. It is an indication of a gaso-
line's ability to resist undesired detona-
tion (knocking). The average of both
the MON (Motor Octane Number) and
