Cooling n
Press n to switch on cooling. The
LED in the button illuminates to
indicate activation. 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
the freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
may inhibit autostops.
Stop-start system 3 154.
Air recirculation system 4
Press 4 to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press 4 again to deactivate air
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 may mist
up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate l.
Maximum cooling
Briefly open the windows so that hot
air can disperse quickly.
● Switch on cooling n.
● Air recirculation system 4 on.
● Press air distribution switch M.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Open all vents.

156Driving and operating● The vehicle is driven at least atwalking speed.
● The climate control system requests an engine start.
● The air conditioning is manually switched on.
If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during engine restart may 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 parking brake. Activate the manual
parking brake without pressing
the release button. Apply as
firmly as possible on a downhill slope or uphill slope. Depress
brake pedal at the same time to
reduce operating force.
For vehicles with electric
parking brake, pull switch m for
a minimum of one second until
control indicator m illuminates
constantly and electric parking
brake is applied 3 112.
● Switch off the engine. ● If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector
lever to position 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
set the selector lever to position
P before removing the ignition
key. Turn the front wheels
towards the kerb.● Close the windows.
● Remove the ignition key from the ignition switch. Turn the
steering wheel until the
steering wheel lock is felt to
engage.
For vehicles with automatic
transmission, the key can only
be removed when the selector
lever is in position P.
● Lock the vehicle.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 216.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
