134Climate controlBus
Adjustable air vents may be located inthe roof frame above the seats. Turn
adjuster to increase / decrease
airflow to the appropriate seat.
Fixed air vents
Additional air vents are located
beneath the windscreen and door
windows and in the foot wells.
Glovebox cooler The air conditioning system can alsokeep the contents of the glovebox
cool.
Maintenance
Air 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.
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 outside
temperature is too low.
ServiceFor optimal cooling performance, it is
recommended to annually check the
climate control system, starting
3 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
206Vehicle careWinter tyresWinter tyres improve driving safety at
temperatures below 7 °C and should
therefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the maximum speed sticker in the driver's field of view.
Tyre designations
E.g. 215/65 R 16 C 109 R215:tyre width, mm65:cross-section ratio (tyre height
to tyre width), %R:belt type: RadialRF:type: RunFlat16:wheel diameter, inchesC:cargo or commercial use88:load index e.g. 109 is
equivalent to approx. 1030 kgR:speed code letter
Speed code letter:
Q:up to 160 km/hS:up to 180 km/hT:up to 190 km/hH:up to 210 km/hV:up to 240 km/hW:up to 270 km/hChoose a tyre appropriate for the
maximum speed of your vehicle.
The maximum speed is achievable at kerb weight with driver (75 kg) plus
125 kg payload. Optional equipment
could reduce the maximum speed of
the vehicle.
Directional tyres
Fit directional tyres such that they roll in the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
The tyre pressure information label
on the driver's door frame indicates the original equipment tyres and the
correspondent tyre pressures.
Always inflate tyres to the pressures
shown on the label.
Tyre pressures 3 252.The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 233.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 252.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct adjustment of tyre pressure.
Vehicle care225Interior care
Interior and upholstery
Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean leather upholstery with clear
water and a soft cloth. In case of
heavy soiling, use leather care.
The instrument cluster and the
displays should only be cleaned using a soft damp cloth. If necessary use a
weak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
belts or studded jeans.
Plastic and rubber parts
Plastic and rubber parts can be
cleaned with the same cleaner as
used to clean the body. Use interior cleaner if necessary. Do not use any
other agent. Avoid solvents and petrol in particular. Do not use high-
pressure jet cleaners.
Customer information259This data includes, for example:● Vehicle status information (e.g. wheel rotation rate, speed,
movement delay, lateral
acceleration, "seatbelts
fastened" display),
● Ambient conditions (e.g. temperature, rain sensor,
distance sensor).
Most of this data is volatile and is processed only in the vehicle itself,and not beyond the operating time.
Moreover, many control units include
data storage device (amongst others the vehicle key). This is used to allow
information to be documented
temporarily or permanently on vehicle
condition, component stress,
maintenance requirements and
technical events and errors.
The following information, for
example, is stored:
● System component operating states (e.g. fill level, tyre
pressure, battery status),
● State of charge of the high voltage battery, estimated range
(in the case of electric vehicles),● Faults and defects in important system components (e.g. lights,
brakes),
● System reactions in special driving situations (e.g. triggeringof an airbag, actuation of the
stability control systems),
● Information on events damaging the vehicle.
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services, the operating data saved can be read together withthe vehicle identification number andused if necessary. Staff working for
the service net-work (e.g. garages,
manufacturers) or third parties (e.g.
breakdown services) can read the
data from the vehicle. Services
include repair services, maintenance
processes, warranty cases and
quality assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data which has been read
out documents the technical conditionof the vehicle or individual
components and assists with fault
diagnosis, compliance with warranty
obligations and quality improvement.
This data, in particular information on
component stress, technical events,
operator errors and other faults, is
transmitted to the manufacturer
where appropriate, together with the vehicle identification number. The
manufacturer is also subject to
product liability. The manufacturer
potentially also needs operating data
from vehicles for product recalls.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs.
Comfort and infotainment
functions
Comfort settings and custom settings can be stored in the vehicle and
changed at any time.
