recirculation mode
Points to observe before use You can deactivate the flow of fresh air if
unpleasant odors are enteringt he vehicle
from outside. The air already inside the
vehicle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in
particular at low temperatures. Only use air-
recirculation mode briefly to prevent the
windows from fogging up.
The operation of air-recirculation mode is the
same for all control panels.

i If the maximum engine speed for the shift
range is reached and you continue to
accelerate, the automatic transmission
shifts up, even if the shift range is restricted. This prevents the engine from

installed only on the CLS 63 AMG.
The AMG brake systems are designed for
heavy loads. This may lead to noise when

R Environmental conditions, such as
temperature and humidity
The wear of individualc omponentsofthe
brake system, such as the brake pads/linings
or brake discs, depends on the individual
driving style and operating conditions.
For this reason, it is impossibletos tate a

circumstances. An aggressive driving style
will lead to high wear. You can obtain further
