208 Controls in detail4-zone automatic climate control*
The climate control is a 4-zone intelligent
climate control system. Your vehicle interi-
or is divided into 4 zones.With the help of a sun sensor, the climate
control determines the relation of the sun
to the vehicle and automatically adjusts
the inside temperature for every individual
zone.
You can set the temperature for each of
the 4 zones separately. These settings can
be assigned to a SmartKey and stored in
memory (
page 168).
The climate control is operational whenev-
er the engine is running. It cools the vehi-
cle’s interior according to the angle and
intensity of the sun’s rays, the outside tem-
perature and the selected temperature.
You can operate the climate control sys-
tem in either the automatic or manual
mode.
Warning!
G
When operating the climate control, the air
that enters the passenger compartment
through the air vents in the footwell can be
very hot or very cold (depending on the set
temperature). This may cause burn or frost-
bite to unprotected skin in the immediate
area of the air vents. Always keep sufficient
distance between unprotected parts of the
body and the footwell air vents. If necessary
change the air flow using the air distribution
controls (
page 206) to direct the air away
from the footwell air vents.

210 Controls in detail4-zone automatic climate control*Setting the temperature
Use temperature control rocker
switches3 and5 (
page 206) or
(
page 207) to separately adjust the air
temperature on each side of the passenger
compartment. You should raise or lower
the temperature setting in small incre-
ments, preferably starting at 72°F (22°C).Increasing

Push top of temperature control rocker
switch3 and/or5 (
page 206) or
(
page 207).
The climate control system will corre-
spondingly adjust the interior air tem-
perature.
Decreasing

Push bottom of temperature control
rocker switch3and/or 5
(page 206) or (

The climate control system will corre-
spondingly adjust the interior air tem-
perature.
Adjusting air distribution
Use the air distribution controls1 and7
(page 206) or (
page 207) or to sepa-
rately adjust the air distribution on each
side of the passenger compartment. The
following symbols are found on the con-
trols:
iWhen operating the climate control
system in automatic mode, you will
only rarely need to adjust the tempera-
ture, air volume and air distribution.

Heater booster system (Diesel engine)
Your vehicle is equipped with a heater
booster system. A PTC heating element
(page 475) ensures that the vehicle inte-
rior is warmed up as quickly as possible
when the engine has not reached its nor-
mal operating temperature yet.
The heater booster system switches on au-
tomatically if required.iThe normal display will appear when
the™ button or the button5 is
pressed again.iIf the cooling function for the air condi-
tioning is switched off with the
±button (
page 206), the heater
booster system is deactivated too.

298 OperationDriving instructionsCoolant temperature
During severe operating conditions and
stop-and-go city traffic, the coolant tem-
perature may rise close to approximately
248°F (120°C).
The engine should not be operated with
the coolant temperature over 248°F
(120°C). Doing so may cause serious en-
gine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G


Driving when your engine is badly over-
heated can cause some fluids, which
may have leaked into the engine com-
partment, to catch fire. You could be se-
riously burned.


Steam from an overheated engine can
cause serious burns and can occur just
by opening the engine hood. Stay away
from the engine if you see or hear steam
coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.

306 OperationEngine compartment
If engine is at normal operating
temperature, wait five minutes before
repeating check procedure.

If engine is not at operating tempera-
ture yet, wait 30 minutes before
repeating check procedure.
If you see the message:
Engine oil level
Not when engine on
Turn off the engine.

If the engine is at normal operating
temperature, wait five minutes before
checking oil.

If the engine is not yet at normal
operating temperature, you must wait
30 minutes before checking oil.If there is excess engine oil with the engine
at normal operating temperature, the
following message will appear:
Engine oil level
Reduce oil level
Have excess oil siphoned or drained
off. Contact an authorized
Mercedes-Benz Center.
For more information on messages in the
display concerning engine oil, see the
“Practical hints” section (
page 387). Adding engine oil
!Excess oil must be siphoned or drained
off. It could cause damage to the
engine and catalytic converter not
covered by the Mercedes-Benz Limited
Warranty.
!Only use approved engine oils and oil
filters required for vehicles with Main-
tenance System (U.S. vehicles) or
FSS PLUS (Canada vehicles). For a list-
ing of approved engine oils and oil fil-
ters, refer to the Factory Approved
Service Products pamphlet in your ve-
hicle literature portfolio, or contact an
authorized Mercedes-Benz Center.
Using engine oils and oil filters of spec-
ification other than those expressly re-
quired for the Maintenance System
(U.S. vehicles) or FSS PLUS (Canada
vehicles), or changing of oil and oil filter
at change intervals longer than those
called for by the Maintenance System
(U.S. vehicles) or FSS PLUS (Canada
vehicles) will result in engine damage
not covered by the Mercedes-Benz
Limited Warranty.

message appears while the engine is run-
ning and at operating temperature, the en-
gine oil level has dropped to approximately
the minimum level.
When this occurs, the warning will first
come on intermittently and then stay on if
the oil level drops further.If no oil leaks are noted, continue to drive
to the nearest service station where the
engine oil should be topped to the required
level with an approved oil specified in the
Factory Approved Service Products pam-
phlet.
