temperatures above approximately 40°F (5°C),
•after approximately 5 minutes, if button S is
pressed.
At high outside temperatures, the system automatically
engages the recirculated air mode for approximately
30 minutes, thereby increasing the cooling capacity
performance. Press O button again to extend the
recirculated air mode.Residual engine heat utilization (REST)
With the engine switched off, it is possible to continue
heating the interior for a short while.

Dust Filter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.
Note:
Keep the air intake grille in front of windshield free of
snow and debris.Important!
This vehicle is equipped with an air conditioner system
that uses R-134a (HFC: hydrofluorocarbon) as a
refrigerant. Repairs should always be performed by a
qualified technician, and refrigerant should be collected
in a recovery system for recycling.
247 Cleaning and care of the vehicle
Te ch n i c a l

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.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.).
Tar st ai ns
Quickly remove tar stains before they dry and become
more difficult to remove. A tar remover is
recommended.

Consumer information
This has been prepared as required of all manufactures
of passenger cars under Title 49, Code of U.S. Federal
Regulations, Part 575 pursuant to the “National Traffic
and Motor Vehicle Safety Act of 1966”.
Uniform tire quality grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
All passenger vehicle tires must conform to federal
safety requirements in addition to these grades.Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
(1
1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
