Press A/C again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) when outside
temperature is above a specific level. 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.
When the cooling system is switched
off, no engine restart will be
requested by the climate control
system during an Autostop.
Exception: defrost system is activated and outside temperature above 0 °C
requests a restart.

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 may mist
up from outside, when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate l.
Automatic air recirculation
An air humidity sensor switches
automatically to external air if internal air humidity is too high.

Adjustable air vents At least one air vent must be open
while cooling is on.
To open the vent, turn the adjuster
wheel towards the bigger W symbol.
Adjust the air amount at the vent
outlet by turning the adjuster wheel.
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, turn the adjuster

Retained power off The following electronic systems can
work until the driver's door is opened
or for ten minutes after the ignition is
switched off:
● power windows
● sunroof
● power outletsStarting the engine
Vehicles with ignition switch
Turn key to position 1 to release the
steering wheel lock.
Manual transmission: operate clutch
and brake pedal.
Automatic transmission: operate
brake pedal and move selector lever
to P or N.
Manual transmission automated:
operate brake pedal.
Do not operate accelerator pedal.
Diesel engines: turn the key to
position 2 for preheating and wait until
control indicator ! extinguishes.
Turn key briefly to position 3 and
release: an automatic procedure operates the starter with a short delay
until the engine is running, see
Automatic Starter Control.
Manual transmission: during an
Autostop, the engine can be started
by depressing the clutch pedal
3 162.
Automatic transmission or manual
transmission automated: during an
Autostop, the engine can be started
by releasing the brake pedal 3 162.
164Driving and operating● The self-cleaning function of theexhaust filter is not active.
● The vehicle was driven at least at
walking speed since the last
Autostop.
Otherwise an Autostop will be
inhibited.
The stop-start system will be
deactivated on inclines of 12% or
more.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details 3 147.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 157.
Vehicle battery discharge protection To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating aredisabled or switched to a power
saving mode. The fan speed of the
climate control system is reduced to
save power.
Restart of the engine by the driverVehicles with manual transmission
Depending on the engine, two
versions of a restart are available.
See engine data to identify the engine
identifier code for your vehicle
3 287.
Conventional restart
Depress the clutch pedal to restart the
engine. For engines with late restart,
this is only possible without
depressing the brake pedal.
Late restart
All petrol engines and the diesel
engines B16DTU and B16DTR have
late restart in addition to conventional
restart. Late restart is only active on
inclines up to 5%.
● Depress the brake pedal.
● Depress the clutch pedal.● Select first gear.
● Release the brake pedal to restart the engine.Vehicles with automatic transmission
or manual transmission automated:
Release the brake pedal or move
selector lever out of D into N or P to
restart the engine.
Restart of the engine by the stop-
start system
On vehicles with manual transmission
which are in a conventional Autostop,
the selector lever must be in neutral
to enable an automatic restart.
On vehicles with manual transmission
which are in an early Autostop, an
automatic restart is possible, when
not in neutral if the brake pedal and
the clutch pedal are depressed.
On vehicles with automatic
transmission or manual transmission
automated, the selector lever must be
in D to enable an automatic restart.
The engine will be restarted
automatically by the stop-start
system, if one of the following
conditions occurs during an Autostop:
Driving and operating165● The stop-start system ismanually deactivated.
● The bonnet is opened.
● The driver's seat belt is unfastened and / or 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 climate control system requests an engine start.
● The desired compartment temperature does not match the
actual temperature.
● 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 the restart might be noticeable.
Note
If a trailer or a bike carrier is
attached, early Autostop and late
restart is deactivated.
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 3 110.
● 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 or
switching off ignition on
vehicles with power button. 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 or switching off ignition on
vehicles with power button.
Turn the front wheels towards
the kerb.
● Close the windows and the sunroof.
● Remove the ignition key from the ignition switch or switch off
ignition on vehicles with power
Driving and operating1671. Apply electric parking brake andswitch off ignition.
2. Press brake pedal and release electric parking brake.
3. Remove key from ignition switch.Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Exhaust filter
The exhaust filter is a particle filter for diesel and gasoline engines.
Automatic cleaning process
The exhaust filter system filters soot particles out of the exhaust gases.
The system includes a self-cleaning
function that runs automatically
during driving without any notification. The filter is cleaned by periodically
burning off the soot particles at high
temperature. This process takes
place automatically under set driving
conditions and may take up to
25 minutes. Typically it needs
between seven and twelve minutes.
Autostop is not available and fuel
consumption may be higher during
this period. The emission of smells
and smoke during this process is
normal.
System requires cleaning Under certain conditions, e.g. drivingshort distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and
if previous driving conditions did not
enable automatic cleaning, it will be
indicated by a warning message in
the Driver Information Centre.
