°F (5
°C),
•after approx. 5 minutes, if button S is pressed.
If the windows should fog up from the inside, switch
from recirculated air back to fresh air.
At high outside temperatures, the system automatically
engages the recirculated air mode thereby increasing
the cooling capacity performance, switching to partially
fresh air within 30 minutes.Residual engine heat utilization
With the engine switched off, it is possible to continue
heating the interior for a short while.
Air volume and distribution are controlled
automatically.
To s e l e c t :

Dust filter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.
Notes:
Do not obstruct the air f low by placing objects on the air
flow–through exhaust slots below the rear window.
Also 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.

cluster displayPractical hints Car care Index Important!
If the electronic key is left in the steering lock position 0
for an extended period of time, it can no longer be
turned in the lock. In this case, remove electronic key
from steering lock and reinsert.
Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the electronic key from the
steering lock. Do not leave the electronic key in steering
lock position 0.Notes:
A warning sounds when the driver’s door is opened
while the electronic key is in steering lock position 1
or 0.
If the electronic key cannot be turned in the steering
lock, the vehic le b attery may no t b e suf f i cien tly charged .
See battery on page 268 or jump starting on page 270.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traf fic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example: Heated seats, rear window
defroster. In addition, the automatic climate air volume
control should be set to the lowest position.
The steering lock can only be unlocked with the vehicle
battery properly charged and connected.

293 Cleaning and care of the vehicle
Technical
data Instruments
and controlsOperation DrivingInstrument
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.
Ad d ition al in fo rm atio n can be foun d in t he boo klet titled
“Vehicle Care Guide”.
Power washer
When using a power washer for cleaning the vehicle
always observe manufacturer’s 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.Tar stains
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.).

311 Consumer information
Technical

cluster displayPractical hints Car care Index 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.
