Cooling n
Press n
to switch on cooling.
Activation is indicated by illumination
of the LED in the button. Cooling is
only functional when the engine is
running and climate control fan is switched on.
Press 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 may inhibit
autostops. Stop-start system 3 126.
Air recirculation system 4
Press 4 to activate air recirculation
mode. Activation is indicated by
illumination of the LED in the button.
Press 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

128Driving and operatingIf the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates.
Control indicator - 3 90.
Restart of the engine by the stop- start system
The selector lever must be in neutral to enable an automatic restart.
If one of the following conditions occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system.
● The stop-start system is manually deactivated
● the bonnet is opened
● the driver's seat belt is unfastened and the driver's door
is opened
● the engine temperature is too low
● the charging level of the vehicle battery is below a defined level
● the brake vacuum is not sufficient
● the vehicle is driven at least at walking speed
● the defrosting function is activated● the climate control systemrequests an engine start
● the air conditioning is manually switched on
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the electrical parking brake.
Pull switch m.
The electric parking brake is
applied when control indicator
m illuminates 3 85.
For maximum force, e.g.
parking with a trailer or on
inclines, pull switch m twice.
● Switch off the engine.

first gear or move the selector
lever to P before removing the
ignition key. On an uphill slope, turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
move the selector lever to P
before removing the ignition
