Warning chimes When starting the engine or whilst
driving
Only one warning chime will sound at
a time.The warning chime regarding
unfastened seat belts has priority
over any other warning chime.
● If the door or bonnet is open.
● If seat belt is not fastened.
● If a certain speed is exceeded with parking brake applied.
● If a warning message or a warning code appears in the
Driver Information Centre.
● If the parking assist detects an object.
● If the fuel level is low.
When the vehicle is parked and/or the driver's door is opened
● With exterior lights on.
During an Autostop ● If the driver's door is opened.
Battery voltage When the battery voltage is running
low, a warning message or warning
code 174 will appear in the Driver
Information Centre.1. Switch off immediately any electrical consumers which are
not required for a safe ride, e.g.
seat heating, heated rear window
or other main consumers.
2. Charge the battery by driving continuously for a while or by
using a charging device.
The warning message or warning
code will disappear after the engine
has been started twice consecutively
without a voltage drop.
If the battery cannot be recharged,
have the cause of the fault remedied
by a workshop.

● Set temperature control to warmest level.
● Switch on heated rear window Ü.
● Open side air vents as required and direct them towards the doorwindows.
122Climate controlMaintenanceAir intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake.
Remove any leaves, dirt or snow.
Pollen filter
The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when the
outside temperature is too low.
Service For optimal cooling performance, it is recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check
Driving and operating129Turn the steering wheel untilthe steering wheel lock is felt to engage.
● Lock the vehicle.
● Activate the anti-theft alarm system.
Notice
In the event of an accident with airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain time.
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.
Diesel particle filter
The diesel particle filter system filters
harmful 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 7 and 12 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.
Under certain driving conditions, e.g.
short 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 control indicator %.
% illuminates when diesel particle
filter is full. Start cleaning process as
soon as possible.
