Notes on using climate control
Automatic climate control
The following contains notes and
recommendations on optimum use of the
automatic climate control.
RSwitch on the air-conditioning system by
turning control knobclockwise to the
desired position (except position0).
RSet the temperature to 72 ‡ (22 †).
RRecommendation for preventing
fogged up windows with low outside
temperatures or rain:switchon for
the air distribution and switchand
off if possible (Ypage 128).
In air-recirculation mode, switchoff
(Ypage 131).
Set airflow controlto a setting between
3and6(Ypage 128).
RRecommendation for rapid cooling or
heating of the vehicle interior:briefly set
airflow controlto a setting between3
and6(Ypage 128).
RRecommendation for a constant
vehicle interior temperature:set airflow
controlto a setting between1and3
(Ypage 128).
RRecommendation for air distribution in
the winter:setand
(Ypage 128).
Recommendation for air distribution in
the summer:setorand
(Ypage 128).
ROnly use the "Windshield defrosting"
function briefly until the windshield is clear
again.
ROnly use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could
otherwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
RVehicles with COMAND:if you change the
settings of the climate control system, the
climate status display appears for three
seconds at the bottom of the screen in the
COMAND display. See also the separate
COMAND operating instructions. You will
see the currentsettings of the various
climate control functions.
ECO start/stop function
During automatic engine switch-off, the ECO
start/stop function only operates at a
reduced capacity. If you require the full
climate control output, you can switch off the
ECO start/stop function by pressing the ECO
button (Ypage 140).

GAWR (Gross Axle Weight Rating)
The GAWR is the maximumgross axle weight
rating. The actual load on an axle must never
exceed the gross axle weight rating. The
gross axle weight rating can be found on the
vehicle identification plate on the B-pillar on
the driver's side.
Speed rating
The speed rating is part of the tire
identification. It specifies the speed range for
which the tire is approved.
GVW (Gross Vehicle Weight)
The gross vehicle weight includes the weight
of the vehicle including fuel, tools, the spare
wheel, accessories installed, occupants,
luggage and the drawbar noseweight, if
applicable.The gross vehicle weight must not
exceed the gross vehicle weight rating GVWR
as specified on the vehicle identification plate
on the B-pillar on the driver's side.
GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible gross
weight of a fully loaded vehicle (the weight of
the vehicle including all accessories,
occupants, fuel, luggage and the drawbar
noseweight, if applicable). The gross vehicle
weight rating is specified on the vehicle
identification plate on the B-pillar on the
driver's side.
Maximum loaded vehicle weight
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa
corresponds to 1 psi. Another unit for tire
pressure is bar. 100 kilopascal (kPa) is the
equivalent of1bar.
Load index
In addition to the load-bearing index, the load
index may also be imprinted on the sidewall
of the tire. This specifiesthe load-bearing
capacity more precisely.
Curb weight
The weight of a vehicle with standard
equipment including the maximum capacity
of fuel, oil and coolant. It also includes the air-
conditioning system and optional equipment
if these are installed in the vehicle, but does
not include passengers or luggage.
Maximum load rating
The maximum load rating in kilograms or
pounds is the maximum weight for which a
tire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one
tire.
Maximum load on one tire
Maximum load on one tire. This is calculated
by dividing the maximum axle load of one axle
by two.
PSI (pounds per square inch)
Astandard unitofmeasure for tire pressure.
