119 Controls in detail
Windshield wipers
Turn the combination switch to posi-
tion U or V.
Intermittent wiping starts with selected
wiping interval.
Vehicles with rain sensor*:
After the initial wipe, pauses between
wipes are automatically controlled by
the rain sensor.
Intermittent wiping interval is depen-
dent on wetness of windshield.Wiping with windshield washer fluid
Press the combination switch in the di-
rection of arrow2 (
page 117) past
the resistance point.
The windshield wiper operates with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system*”
(
page 330).
iIntermittent 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 clutch pedal is depressed (vehicles with
manual transmission
or

the gear selector lever is positionD orR (ve-
hicles with automatic transmission*)
or

the wiper setting is changed using the com-
bination switch
iTo 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.
iVehicles with headlamp cleaning system*:
The headlamp cleaning system* will clean the
headlamps automatically after the first and every
tenth time windshield washer fluid is used while
the engine is running (
page 112).

ters, refer to the Factory Approved Service Prod-
ucts pamphlet (USA only) in your vehicle
literature portfolio, or contact an authorized
Mercedes-Benz Center.
Using engine oils and oil filters of specification

tenance System, or changing of oil and oil filter

451 Practical hints
Jump starting
Jump starting
If the battery is discharged, the engine can
be started with jumper cables and the
battery of another vehicle. Observe the
following:

Jump starting should only be performed
when the engine and catalytic
converter are cold.

Do not start the engine if the battery is
frozen. Let the battery thaw out first.

Only use a12-volt battery to jump start
your vehicle. Jump starting with a high-
er voltage battery could damage the ve-
hicle’s electrical system, which will not
be covered by the Mercedes-Benz
Limited Warranty.

Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.

Always make sure the jumper cables
are not on or near pulleys, fans or other
parts that move when an engine is
started or running.
Warning!G
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting to jump start a frozen battery
can result in it exploding, causing personal
injury.
Read all instructions before proceeding.
!Vehicles with automatic transmission*
and/or 4MATIC:
Do not tow-start the vehicle.
!Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a bat-
tery quick charge unit.
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel generated by repeated
failed starting attempts may damage the catalyt-
ic converter and may present a fire risk.
Make sure the jumper cables do not have loose
or missing insulation.
Make sure the cable clamps do not touch any
other metal part while the other end is still at-
tached to a battery.
Warning!G
Keep flames or sparks away from battery.
Do not smoke.
Observe all safety instructions and precau-
tions when handling automotive batteries
(
page 446).
