188 Controls in detailClimate control (CLK 350)The climate control is operational when-
ever the engine is running. You can oper-
ate the climate control system in either the
automatic or manual mode. The system
cools or heats the interior depending on
the selected interior temperature and the
current outside temperature.Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
The air conditioning will not engage (no
cooling) if the A/C mode is deactivated
(
page 194).
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature).
This may cause burns or frostbite on unpro-
tected skin in the immediate area of the air
vents. Always keep sufficient distance be-
tween unprotected parts of the body and the
air vents. If necessary, use the air distribu-
tion control (
page 187) to direct the air to
air vents in the vehicle interior that are not
in the immediate area of unprotected skin.
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
iSevere conditions (e.g. strong air
pollution) may require replacement of
the filter before its scheduled interval.
A clogged filter will reduce the air
volume to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off, see
“Summer opening feature”
(page 249). The climate control will
then adjust the interior temperature to
the set value much faster.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing
objects on the air flow-through exhaust
slots below the rear window.

Press button, (
page 197).
The indicator lamp on the button goes
out.
Charcoal filter
An activated charcoal filter markedly
reduces bad odors and removes pollutants
from air entering the passenger compart-
ment. The charcoal filter can be activated
or deactivated.
The system switches automatically to the
air recirculation mode, if the

charcoal filter is switched on


carbon monoxide (CO) or nitrogen
oxide (NO
X) concentration of the out-
side air increases beyond a predeter-
mined level
iThe air recirculation mode is deactivat-
ed automatically:

after 5 minutes if the outside
temperature is below
approximately 41°F (5 °C)


after 5 minutes if the air condition-
ing is turned off


after 30 minutes if the outside
temperature is above
approximately 41°F (5 °C)
iIf you press and hold button,, the
side windows and tilt/sliding sunroof*
will return to their previous position.
A side window or tilt/sliding sunroof*
will only return to its previous position
if it has not been moved to another po-
sition using the respective side window
switch or tilt/sliding sunroof* switch
after it was closed with button,.
A side window or tilt/sliding sunroof*
that was moved will remain in its cur-
rent position if button, is used to
re-open the remaining side windows or
tilt/sliding sunroof*.
iThe automatic air recirculation mode
does not function if theA/C (indicator
lamp on button2 or 9 not lit)
mode is deactivated, or if the outside
temperature has fallen below 41°F
(5°C).

454 Technical dataFuels, coolants, lubricants, etc.Engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters re-
quired for vehicles with Maintenance
System (U.S. vehicles) or FSS (Canada
vehicles). For a listing of approved engine
oils and oil filters, refer to the Factory Ap-
proved Service Products Pamphlet, or
contact an authorized Mercedes-Benz
Center.
Engine oil additives
Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from
blending oil additives are not covered by
the Mercedes-Benz Limited Warranty.Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air
conditioning system.
Never use R-12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the
system will occur.
Brake fluid
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere.
Only brake fluid approved by
Mercedes-Benz is recommended. An
authorized Mercedes-Benz Center will
provide you with additional information.
!Using engine oils and oil filters of spec-
ification other than those expressly re-
quired for the Maintenance System
(U.S. vehicles) or FSS (Canada vehi-
cles), or changing of oil and oil filter at
change intervals longer than those
called for by the Maintenance System
(U.S. vehicles) or FSS (Canada vehi-
cles) will result in engine damage not
covered by the Mercedes-Benz Limited
Warranty.
Please follow Maintenance System
(U.S. vehicles) or FSS (Canada vehi-
cles) recommendations for scheduled
oil changes. Failure to do so will result
in engine damage not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Under extremely strenuous operating condi-
tions, this moisture content can lead to the
formation of bubbles in the system, thus re-
ducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle's Mainte-
nance Booklet for replacement interval.
