143 Controls in detail
Instrument cluster
Coolant temperature indicator
During severe operating conditions, e.g.
stop-and-go traffic, the coolant tempera-
ture may rise close to 248°F (120°C).
The engine should not be operated with
the coolant temperature above 248°F
(120°C). Doing so may cause serious en-
gine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Trip odometer
Make sure you are viewing the trip odome-
ter display (
page 145).

If it is not displayed, press the è or
ÿ repeatedly until the trip odome-
ter appears.

Press and hold the reset button on the
instrument cluster (
page 24) until
the trip odometer is reset.
Warning!
G


Driving when your engine is 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 hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.
iExcessive coolant temperature trigger
a warning in the multifunction display
(page 361).

196 Controls in detailDual-zone automatic climate controlThe climate control is operational whenev-
er the engine is running. You can operate
the climate control system in either the au-
tomatic or manual mode. The system cools
or heats the interior depending on the se-
lected interior temperature and the cur-
rent 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 AC
OFF
mode is activated or
AC mode is deactivated (
page 201).
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 burns 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 194) to direct the air away
from the footwell air vents.
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 pollu-
tion) may require replacement of the fil-
ter 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.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.

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.

Standing water
Passenger compartmentDriving abroad
Abroad, there is an extensive
Mercedes-Benz service network at your
disposal. If you plan to drive into areas
which are not listed in the index of your
Mercedes-Benz Center directory, you
should request pertinent information from
your authorized Mercedes-Benz Center.Control and operation of radio trans-
mitter
COMAND, radio and telephone*
!Do not drive through flooded areas or
water of unknown depth. Before driving
through water, determine its depth.
Never accelerate before driving into
water. The bow wave could force water
into the engine and auxiliary equip-
ment, thus damaging them.
If you must drive through standing wa-
ter, drive slowly to prevent water from
entering the passenger compartment
or the engine compartment. Water in
these areas could cause damage to
electrical components or wiring of the
engine or transmission, or could result
in water being ingested by the engine
through the air intake causing severe
internal engine damage. Any such dam-
age is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Always fasten items being carried as secure-
ly as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and cause injury
to vehicle occupants unless the items are
securely fastened in the vehicle.
The trunk is the preferred place to carry ob-
jects.
Warning!
G
Please do not forget that your primary re-
sponsibility is to drive the vehicle safely.
Only operate the COMAND (Cockpit Man-
agement and Data System), radio or tele-
phone
1 if road, weather and traffic
conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
