382 Technical dataFuels, coolants, lubricants, etc.Windshield and headlamp washer system
Both the windshield and headlamp washer
systems are supplied from the windshield
washer fluid reservoir.
The windshield and headlamp washer fluid
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
“S” and water:


1 part “S” to 100 parts water
(1.34 floz [40 ml] “S” to 1 gallon [4.0 l] wa-
ter).
For temperatures below “freezing point”
use MB Windshield Washer Concentrate
“S” and commercially available premixed
windshield washer solvent/antifreeze:


1 part “S” to 100 parts solvent
(1.34 floz [40 ml “S” to 1 gallon [4.0 l] sol-
vent).
Warning!
G
Washer solvent/antifreeze is highly flamma-
ble. Do not spill washer solvent/antifreeze
on hot engine parts because it may ignite

vehicle information and to change
component settings. Information and
messages appear in the multifunction

Engine number
The number set by the manufacturer
and placed on the cylinder block to
uniquely identify each engine pro-
duced.

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

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 gear.
This very quickly accelerates the vehi-
cle and should not be used for normal
acceleration needs.
