Cooling n
Press button
n to switch on cooling.
Activation is indicated by the LED in
the button. Cooling is only functional
when the engine is running and
climate control fan is switched on.
Press button n again to switch off
cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel. Activated cooling might inhibit
autostops.
Air recirculation system 4
Press button 4 to activate air
recirculation mode. Activation is
indicated by the LED in the button.
Press button 4 again to deactivate
recirculation mode.9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen might mist
up from outside, when cold air is

FaultThe yellow control indicator u flashes
to indicate that the system is not ready for conditions to operate, due to the high temperature (approx.
350 - 400 °C) of friction material,
through severe or repeated braking. It
will extinguish when the temperature
drops below 350 °C.
The yellow control indicator u
illuminates when there is a
malfunction in the system, due to the
extremely high temperature
(over 400 °C) of friction material,
through severe or repeated braking. It will extinguish when the temperaturedrops below 350 °C. These
temperatures may differ according to
vehicle conditions or outside
conditions.
Flashing or illumination of the yellow
control indicator u reminds the driver
that the friction material needs to cool
down: drive the vehicle without
braking as much as possible. If the
control indicator does not extinguish,
have the cause of the fault remedied
by a workshop.DSC control indicators u 3 87.
Automatic level control The rear level of the vehicle is
automatically adjusted to the load
conditions while driving. Suspension
and ground clearance are increased,
which improves driving conditions.
The automatic level control is
activated after the vehicle has been
driven for some distance, depending
on the vehicle load and the road
conditions.
Do not use full payload in the event of
a fault. Have the cause of the fault
remedied by a workshop.
