Resetting the maintenance service
indicator
In the event that the maintenance service on
your vehicle is not carried out at an authorized
Mercedes-Benz Center, you can have the
maintenance service indicator reset.
The automotive maintenance facility carrying
out the maintenance service will find the
information for resetting the maintenance
service indicator in the maintenance-relevant
literature for your vehicle.
Such literature is available at any authorized
Mercedes-Benz Center or directly from
Mercedes-Benz.
! If the maintenance service indicator was
reset inadvertently, have an authorized
Mercedes-Benz Center correct it.
Only reset the maintenance service
indicator if the proper maintenance service
has been performed. Not following the
proper maintenance service as described
in the Maintenance Booklet will result in
engine damage and/or other vehicle
damage not covered by the Mercedes-Benz
Limited Warranty.
Vehicle care
Cleaning and care of the vehicle
Notes
Regular and proper care will help to maintain
the value of your vehicle.
GWarning!
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the
particular container. Always open your
vehicle’s doors or windows when cleaning the
inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and keep
them out of reach of children.
! When cleaning the vehicle, do not use
scouring agents. Never apply strong force
and only use a soft, wet cloth or sponge.
Otherwise you may scratch or damage the
surface to be cleaned.
While in operation, even while parked, your
vehicle is subjected to varying external
influences which, if gone unchecked, can
attack the paintwork as well as the vehicle
underbody and cause lasting damage.
Such damage is caused not only by extreme
and varying climatic conditions, but also by:
R Air pollution
R Road salt
R Tar
R Gravel and stone chipping
To avoid paint damage, you should
immediately remove:
R Grease and oil
R Fuel
R Coolant
R Brake fluid
R Bird droppings
R Insects
R Tree resins etc.
Frequent washing reduces and/or eliminates
the aggressiveness and potency of the above
adverse influences.
More frequent washings are necessary to
deal with unfavorable conditions:
R near the ocean
R in industrial areas (smoke, exhaust
emissions)
R during winter operation
You should check your vehicle from time to
time for stone chipping or other damage. Any
damage should be repaired as soon as
possible to prevent corrosion.
In doing so, do not neglect the underbody of
the vehicle. A prerequisite for a thorough
check is a washing of the underbody followed
by a thorough inspection. Damaged areas
need to be re-undercoated.354Vehicle careOperation

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 transmission remains in
neutral position N. Observe instructions,
see “Shifting into neutral position N”
( Y page 263).
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 moldings
XFor 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.
Lamp 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.
Cleaning the Parktronic system sensors
Parktronic system sensors are located in the
front and rear bumper.
XOnly clean Parktronic system sensors :
by hand.XUse a mild vehicle wash detergent, such as
Mercedes-Benz approved Car Shampoo,
with plenty of water and a soft, non-
scratching cloth to clean Parktronic system
sensors : on the bumpers.

R with a dry cloth and strong pressure
R with aggressive cleaning agents
You could otherwise damage the camera.
Cleaning the windows and the wiper
blades
! The windshield wipers must be in a
vertical position before folding them away
from the windshield. They could otherwise
damage the hood.
Never open the hood when the wiper arms
are folded forward.
XMake sure the hood is fully closed.XSwitch on the ignition.XTurn combination switch to wiper setting
° (Y page 253).XWith wiper arms in vertical position, switch
off the ignition.GWarning!
For safety reasons, switch off wipers and
remove SmartKey from starter switch before
cleaning the windshield and/or the wiper
blades. KEYLESS-GO: Make sure the vehicle’s
on-board electronics have status 0.
Otherwise, the wiper motor could suddenly
turn on and cause injury.
! Do not pull on the wiper blade inserts.
They could tear.
XFold the wiper arms forward until they snap
into place.XClean the windshield and the wiper blade
inserts with a clean cloth and mild
detergent solution.XUse a soft, clean cloth and a mild window
cleaning solution on all outside and inside
glass surfaces.
An automotive glass cleaner is
recommended.
! Fold the windshield wiper arms back onto
the windshield before pressing the
KEYLESS-GO start/stop button or turning
the SmartKey in the starter switch.
Hold on to the wiper when folding the wiper
arm back. If released, the force of the
impact from the tensioning spring could
crack the windshield.
! To clean the window interior, do not use
a dry cloth, abrasives, solvents or cleaners
containing solvents. Do not touch the
inside of the windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.
Light alloy wheels
If possible, clean wheels once a week.
XUse Mercedes-Benz approved Wheel Care,
a soft bristle brush and a strong spray of
water for cleaning the light alloy wheels.
! Only use acid-free cleaning materials.
Acid may cause corrosion or damage the
clear coat.
! The vehicle should not be parked for an
extended period of time immediately after
it has been cleaned. This applies especially
after the wheel rims have been cleaned
with wheel rim cleaner. Wheel rim cleaners
can lead to increased corrosion of the
brake disks and brake pads. Non-approved
wheel cleaners may also damage the wheel
paint if the vehicle is not driven after
cleaning.
