cluster displayPractical hints Car care Index Automatic climate control
The system is always at operational readiness, except
when manually switched off.
The automatic climate control only operates with the
engine running.
The temperature selector should be left at the desired
temperature setting. The temperature selected is
reached as quickly as possible.
The system will not heat or cool any quicker by setting a
higher or lower temperature.
The desired interior temperature and air distribution
can be selected separately for the left and right side of
the passenger compartment. Adjust the temperature
settings in small increments.
The automatic climate control removes considerable
moisture from the air during operation in the cooling
mode. It is normal for water to drip on the ground
through ducts in the underbody.
The air conditioning will not engage (no cooling) if the
economy mode AC
OFF
is selected, see page 176. Notes:
The current settings (Temperature, Air volume, AC
OFF,
Activated charcoal filter, ON / OFF) are stored for each
electronic key before the electronic key is removed from
the starter switch or when the vehicle is locked using
the KEYLESS-GO-card (vehicles with keyless-go), see
key dependent memory settings on page 111.
Do not obstruct the air flow by placing objects on the air
flow-through exhaust slots below the rear window.
Also keep the air intake grill in front of the windshield
free of snow and debris.
The storage compartment between the front seats can be
ventilated. See page 178 for notes on ventilating the
storage space under the armrest in the center console.
The air conditioner switches itself off for its own
protection if refrigerant is lost. No cooling will then take
place. Economy mode AC
OFF
cannot be switched off.
Have the air conditioner checked by a Mercedes-Benz
Center should this happen.
If the vehicle interior has been heated by direct sunlight
and is very hot, ventilate the interior (open door or
windows for a short period) before driving off.

Dust filter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.Automatic maximum cooling (MAXCOOL)
With the automatic climate control set to automatic, the
system will automatically switch to maximum cooling
output when necessary to achieve the set temperature
quickly, see page 171. The display shows
“AUTO MAXCOOL”.
The temperature setting cannot be changed during
maximum cooling operation.
Note:
By pressing one of the temperature control buttons, the
system will display briefly (approx. 5 seconds) the set
temperature in the display.

We recommend that automatic mode be selected and
that the temperatures on the left and right set to
72
°F(22
°C). Please make changes from this setting to
suit your personal requirements.
Press A on the air volume switch. The display shows
“AUTO”. Air volume is set automatically.

Controlling the rear air conditioner from the front
automatic climate control panel
The rear air conditioner can be switched off and the
blower and temperature settings can be changed from
the automatic climate control panel in the center
console.
Press A on the air volume switch and hold until the
display illustrated above is shown.The rear automatic climate control can be switched on
and off by pressing the Mbutton. The blower setting
for the rear automatic climate control can be controlled
with the air volume switch and the temperature setting
for the rear air conditioner can be set with the
temperature control switches.
Notes:
The message in the display disappears approximately
4 seconds after the button is pressed for the last time
and the automatic air conditioner switches to normal
operation.
During maximum cooling the display in the rear
passenger compartment shows “MAXCOOL”.

COOLANT (coolant level)
* C = Category, see page 309When this message appears while driving, the coolant
level has dropped below the required level. If no leaks
are noticeable and the engine temperature does not
increase, continue to drive to the nearest service station
and have coolant added to the coolant system.The low engine coolant level warning should not be
ignored. Extended driving with the symbol displayed
may cause serious engine damage not covered by the
Mercedes-Benz Limited Warranty.
In cases of major or frequent minor coolant loss, have
the cooling system checked at your authorized
Mercedes-Benz Center as soon as possible.
Notes:
Do not drive without coolant in the cooling system. The
engine will overheat causing major engine damage.
Monitor the coolant temperature gauge while driving,
see page 115.
See page 344 for instructions on topping up the coolant.Line 1 Line 2 C*
COOLANT CHECK LEVEL! 2
Wa r n i n g !
Do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which may
burn if it comes into contact with hot engine parts.
You can be seriously burned.

1 This may indicate that the poly-V-belt has broken. Should this
condition occur, the poly-V-belt must be replaced before continuing
to operate the vehicle. Otherwise, the engine will overheat due to
an inoperative water pump which may result in damage to the
engine. Do not continue to drive the vehicle with this message
displayed. Doing so could result in serious engine damage that is
not covered by the Mercedes-Benz Limited Warranty.
2 The cooling fan for the coolant is faulty. Observe the coolant
temperature gauge. See page 115
During severe operating conditions and stop-and-go city
traffic, the coolant temperature may rise close to the red
marking.
The engine should not be operated with the coolant
temperature in the red zone. Doing so may cause
serious engine damage which is not covered by the
Mercedes-Benz Limited Warranty.

Wa r n i n g !
Driving when your engine is badly overheated can
cause some fluids which may have leaked into the
engine compartment to catch fire. You could be
seriously 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 it cools down.
