When the airbag inflates, smoke is released. This is not a sign of a fire in the
vehicle.
Triggering conditions
It is not possible to generally determine which deployment conditions apply to
the airbag system in every situation. The important factors here are the hard-
ness of the object with which the vehicle collides, the angle of impact, vehicle
speed etc.
Deceleration during impact plays an important role in the deployment of the
airbags. If the vehicle deceleration which occurs and is measured remains be-
low the prescribed reference values specified in the control unit, the airbags
are not deployed although the vehicle may well suffer severe damage to the
bodywork as a consequence of the accident.
The following airbags will be deployed in the event of a severe frontal
collision.

NotevThe air inlet in front of the windscreen must be free of e.g. ice, snow or
leaves to ensure that the heating and cooling system operates properly.v
After switching on the cooling Condensation from the evaporator of the air
conditioning may drip down and form a puddle below the vehicle. This is not a
leak!
v
If the coolant temperature is too high, the cooling system is switched off to
ensure that the engine cools down.

CAUTIONWe recommend not smoking in the vehicle when the recirculating air opera-
tion is switched on. The smoke sucked from the interior is deposited on the
evaporator of the air conditioner. This produces a permanent odour when the
air conditioning system is operating which can only be eliminated through con-
siderable effort and expense (replacement of compressor).
Note
If recirculated air mode is switched on for around 15 minutes, the symbol 3
will begin to flash in the Climatronic display as a sign that the recirculated air
mode is switched on long-term. If the recirculated air mode is not switched
off, the symbol 3 flashes for around 5 minutes.
