Overview of climat ec ontrol systems
General notes Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To preven tt he windows from fogging up:R
switch off climate control only briefly R
switch on air-recirculation mode only briefly R
switch on the cooling with air dehumidifica-
tion function R
switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
Climate control can only be operated when the
engin eisr unning. Optimum operation is only
achieved with the side windows and roof closed. i When the weather is warm, ventilate the
vehicle for ab rief period. This will speed up
the cooling process and the desired vehicle
interior temperature will be reached more
quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants
and odors. Ac logged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should alway so bserve
the interval for replacing the filter, which is
specified in the Maintenance Booklet. As it
depends on environmental conditions ,e .g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance Book-
let.

Drive sensibly –s ave fuelObserve the following tips to save fuel: R
The tires should always be inflated to the rec-
ommended tire pressure. R
Remove unnecessary loads. R
Warm up the engin eatl ow engin es peeds.R
Avoid frequen ta cceleration or braking.R
Observe the servic ei ntervals in the Mainte-
nanc eB ooklet or in the servic ei nterval dis- play. Have all the maintenanc ew ork carried in
accordance with Daimler AG regulations.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
G WARNING
Drinkin ga nd driving and/or takin gd rugs and
driving are very dangerous combinations.
Even as mall amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of as erious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Therefor en ever leave
the engin er unning in enclosed spaces with-
out sufficien tv entilation.
Certain engin es ystems are designed to keep
the level of poisonous component sine xhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications .A lways have
work on the engin ec arried out at aq ualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Ben zC enter for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at aq ualified specialist
workshop.
The engin es ettings must not be changed under
any circumstances. Furthermore, all specific
servic ew ork must be carried out at regular
intervals and in accordance with the Mercedes-
Ben zs ervic er equirements. Details can be found
in the Maintenance Booklet.134
