and auxiliary heating. It allows the temperature of
the interior to be adjusted before the journey
starts. The interior is ventilated or heated de‐

Air conditioning
pending on the set temperature and ambient
temperature. When doing so, the system uses
any available residual heat from the engine or the
vehicle's fuel for generating heat.
General
The system can be switched on and off directly
or for a preselected departure time.
The switch-on time is calculated based on the
outside temperature. The system will switch on
in good time before the preselected departure
time.
If ambient temperatures are below 0 ℃/32 ℉,
water vapour condenses and wets the ground
underneath the vehicle.
Safety notes
A blocked exhaust pipe or inadequate ventila‐
tion can allow harmful exhaust fumes to enter
the vehicle. The exhaust fumes contain pollu‐
tants which are colourless and odourless. In en‐
closed spaces, exhaust fumes can also build up
outside the vehicle. There is a danger of fatal
injury. Keep the exhaust pipe clear and ensure
sufficient ventilation. Do not switch on the auxil‐
iary heating in enclosed spaces, for example
closed garages.
When the auxiliary heating is operating, high
temperatures can be generated under the
body, for example because of the exhaust sys‐
tem. If flammable materials come into contact
with hot parts of the exhaust system, these ma‐
terials can catch fire. There is a risk of fire.
Make sure that no flammable materials, for ex‐
ample leaves, grass, gas, petrol, oil or other
flammable objects, can come into contact with
vehicle parts when the auxiliary heating is oper‐
