XThoroughly spray the vehicle with a
diffused jet of water.XDo not spray directly towards the
ventilation intake.XUse plenty of water and rinse the sponge
and chamois frequently.XRinse with clean water and dry with a
chamois thoroughly.
Do not allow cleaning agents to dry on the
finish.
Automatic car wash
You can have your vehicle washed in an
automatic car wash from the start. Brushless
car washes are preferable.
XTo protect the filter system, activate the air
recirculation mode using button d on
the climate control panel.
! Do not clean your vehicle in an automatic
touchless car wash which uses caustic
spray. Caustic spray will damage the paint
or ornamental moldings.
If the vehicle is very dirty, prewash it before
running it through the automatic car wash.
! Make sure the combination switch is set
to wiper setting $. Otherwise, the rain
sensor could activate and cause the wipers
to move unintentionally. This may lead to
vehicle damage.
Due to the width of the vehicle, fold in
exterior rear view mirrors prior to running
the vehicle through an automatic car wash
to prevent damage to the mirrors.
XWhen taking the vehicle through an
automatic conveyor-type car wash:
Make sure the automatic transmission
remains in neutral position N. Observe
instructions, see “Remaining in neutral
position N” ( Y page 115).
When leaving the automatic car wash, make
sure the mirrors are folded out.
After running the vehicle through an
automatic car wash, wipe any wax off of the
windshield and the wiper blade inserts. This
will prevent smears and reduce wiping noise
which can be caused by residual wax on the
windshield.
Ornamental moldingsXFor regular cleaning and care of ornamental
moldings, use a damp cloth.
! Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings
may have chrome appearance, they could
be made of anodized aluminum that will be
damaged when cleaned with chrome
cleaner. Instead, use a damp cloth to clean
those ornamental moldings.
For very dirty ornamental moldings of
which you are sure are chrome-plated, use
a chrome cleaner. If in doubt whether an
ornamental molding is chrome-plated,
contact an authorized Mercedes-Benz
Center.
Headlamps, brake lamps, tail lamps,
side markers, turn signal lenses
XUse a mild vehicle wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water.
! Only use window cleaning solutions that
are suitable for plastic lamp lenses.
Window cleaning solutions which are not
suitable may damage the plastic lamp
lenses of the headlamps. Therefore, do not
use abrasives, solvents or cleaners that
contain solvents.

KEYLESS-GO button is in position 1.
Otherwise the alternator and other
electronic components could be severely
damaged.
Have the battery checked regularly at an
authorized Mercedes-Benz Center.
Refer to Maintenance Booklet for
maintenance intervals or contact an
authorized Mercedes-Benz Center for
further information.

the vehicle unless the accessory battery
charge unit approved by Mercedes-Benz is
being used. Gases may escape during
charging and could cause an explosion that
may result in personal injury, paint damage or
corrosion.
An accessory battery charge unit specially
adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available. It permits the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Center for
information and availability.
Charge battery in accordance with the
separate instructions for the accessory
