1Cross bar
2Knurled-head screws
3Clamping plates
4Protective strips
The cross bars (1) should only be used as guard rails to
prevent luggage from sliding. They must only be
installed above the protective strips (4).Installation:
1. Loosen knurled-head screws (2) and turn clamping
plates (3) to side.
2. Mount cross bar (1) on roof railings.
3. Turn clamping plates (3) back under roof railings
and tighten the knurled-head screws (2).
Important!
Do not use the pop-up feature of the sliding / pop-up roof
when positioning and / or placing luggage above it, to
prevent damage to the sliding / pop-up roof panel.
Never place luggage on cross bars only, but load it on
the protective strips, distribute it evenly over the entire
area and fasten it securely.

Long cargo items should not extend beyond the vehicle
length and should be securely fastened at the front and
rear.
Prior to and during an extended trip check the roof load,
and retighten the knurled-head screws if necessary.
The heaviest portion of the cargo should always be kept
as low as possible since it influences the handling
characteristics of the vehicle.
When driving without roof luggage, the cross bars may
be removed to reduce wind noise.
For load capacity see page 321.Note:
Use only roof racks approved by Mercedes-Benz. They
mount to the roof railings and do not require additional
supports (e.g. suction cups or legs). Such supports may
lead to marring of the paint or denting of the roof. For
further information inquire at your Mercedes-Benz
Center.

Cleaning and care of the vehicle
In operation, your vehicle is subjected to varying
external influences which, if gone unchecked, can
attack the paintwork as well as the underbody and
cause lasting damage.
Such damage is caused not only by extreme and varying
climatic conditions, but also by air polution, road salt,
tar, gravel and stone chipping. Grease and oil, fuel,
coolant, brake fluid, bird droppings, insects, tree resins
etc. should be removed immediately to avoid paint
damage. 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; for example, near the ocean, in
industrial areas (smoke, exhaust emissions), or 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 the start of
corrosion.
In doing so, do not neglect the underside 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 reundercoated.
Your vehicle has been treated at the factory with a wax-
base ru stproof ing in th e body cavities w hich will la st for
the lifetime of the vehicle. Post-production treatment is
neither necessary nor recommended by Mercedes-Benz
because of the possibility of incompatibility between
materials used in the production process and others
applied later.
We have selected car-care products and compiled
recommendations which are specially matched to our
vehicles and which always reflect the latest technology.
You can obtain Mercedes-Benz approved car-care
products at your authorized Mercedes-Benz Center.
Wa r n i n g !
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.

Te ch n ica l
data Instruments

cluster displayPractical hintsCar careIndex Scratches, corrosive deposits, corrosion or damage due
to negligent or incorrect care cannot always be removed
or repaired with the car-care products recommended
here. In such cases it is best to seek aid at your
authorized Mercedes-Benz Center.
The following topics deal with the cleaning and care of
your vehicle and give important “how-to” information as
well as references to Mercedes-Benz approved car-care
products.
Additional information can be found in the booklet titled
“Vehicle Car Guide”.
Power washer
When using a power washer for cleaning the vehicle
always observe manufacturers’ operating instructions.
Caution!
Never use a round nozzle to power wash tires. The
intense jet of water can result in damage to the tire.
Always replace a damaged tire.
Always keep the jet of water moving across the surface.
Do not aim directly at electrical parts, electrical
connectors, seals, or other rubber parts.Ta r st a in s
Quickly remove tar stains before they dry and become
more difficult to remove. A tar remover is
recommended.
Paintwork, painted body components
Mercedes-Benz approved Paint Care should be applied
when water drops on the paint surface do not “bead up”,
normally in 3 to 5 months, depending on climate and
washing detergent used.
Mercedes-Benz approved Paint Cleaner should be
applied if paint surface shows signs of dirt embedding
(i.e. loss of gloss).
Do not apply any of these products or wax if your
vehicle is parked in the sun or if the hood is still hot.
Use the appropriate MB-Touch-Up Stick for quick and
provisional repairs of minor paint damage (i.e. chips
from stones, vehicle doors etc.).
