When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid
KEYLESS GO key is in the vehicle by periodi-
cally establishing radio contact. G

LESS GO button on the gear selector lever.
They could endanger themselves and oth-
ers. Never leave children unsupervised in
the vehicle. Switch off the engine and take

Risk of accident
Do not keep any objects in the driver's foot-
well. If you use a floormat or carpet in the
driver's footwell, make sure that they are
correctly secured and that there is suffi-
cient clearance for the pedals.
Objects could otherwise get between the
pedals in the event of sudden braking or
acceleration. You may then no longer be
able to brake, change gear or accelerate as
intended. This may result in an accident and
injury. G
Risk of poisoning
Never leave the engine running in enclosed
spaces. The exhaust gases contain carbon
monoxide. Inhaling exhaust fumes consti-
tutes a health hazard and could lead to loss
of consciousness or even death.
! Do not depress the accelerator pedal
when starting the engine.
i If you depress the brake when starting the
engine, pedal travel will be unusually long
and there will be less pedal resistance. Cont

Air conditioning
163General notes
2-zone Thermatic controls the temperature of
the vehicle interior and filters out undesirable
substances from the air.
4-zone Thermotronic* controls the tempera-
ture and the humidity of the vehicle interior
and filters out undesirable substances from
the air.
2-zone Thermatic/4-zone Thermotronic* is
only operational when the engine is running.
Optimum operation is only achieved when
you drive with the side windows and sliding/ tilting sunroof*/panorama sliding sunroof*
closed.
i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the sum-
mer opening feature (Y page 109). This will
speed up the cooling process and the
desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and completely filters out
pollen. A clogged filter reduces the amount of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. G
Risk of accident
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. This may obstruct your view
of the traffic situation, thereby causing an
accident. Cont
