Climate control105Air 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.
Service For optimal cooling performance, it is
recommended that the climate control system be checked annually, 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 operating109
The engine will be switched off while
the ignition stays on if the required conditions are met.
An Autostop is indicated when Ï
illuminates green in the instrument
cluster.
During an Autostop, the brake
performance will be maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited.
■ The stop-start system is not manually deactivated
■ the bonnet is fully closed
■ the driver's door is closed or the driver's seat belt is fastened
■ the vehicle battery is sufficiently charged and in good condition
■ the engine is warmed up
■ the engine coolant temperature is not too high
■ the ambient temperature is not too low
■ the defrosting function is not activated
■ the climate control system does not
inhibit an Autostop
■ the brake vacuum is sufficient
■ the vehicle has moved since the last Autostop
■ the diesel particle filter self- cleaning function is in progress
An Autostop may be less available as
the ambient temperature approaches
freezing point.Certain settings of the climate control system may inhibit an Autostop. See
Climate control chapter for further
information 3 94.
Immediately after motorway driving
an Autostop may be inhibited.
Autostop may also be inhibited
temporarily if the vehicle battery has
been recharged by an external
source.
New vehicle running-in 3 106.
Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the
driver
Depress the clutch pedal to restart the
engine. If the selector lever has been
shifted out of N or other conditions are
not met, start using the ignition key.
Control indicator Ï will extinguish in
the instrument cluster when the
engine is restarted.
152Vehicle care
In accordance with country-specific
regulations, a notice indicating the
maximum permissible speed for the
tyres must be affixed within the
driver's field of vision.
Tyre designationsE.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 100 mphS=up to 112 mphT=up to 118 mphH=up to 130 mphV=up to 150 mphW=up to 168 mphTyre pressure
Check the pressure of cold tyres at least every 14 days and before any
long journey. Do not forget the spare
wheel.
Tyre pressures 3 189.
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.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
Rear-wheel drive, with twin rear
wheels When inflating the outer tyre, the
inflation tube should be passed
between the two wheels.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than
2 mm.
Vehicle care165
Windows and windscreen wiperblades
Use a soft lint-free cloth or chamois
leather together with window cleaner
and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
Wheels and tyres
Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.Paintwork damage
Rectify minor paintwork damage with
a touch-up pen before rust forms.
Have more extensive damage or rust areas repaired by a workshop.
Underbody Some areas of the vehicle underbody
have a PVC undercoating while other
critical areas have a durable
protective wax coating.
After the underbody is washed, check the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Towing equipment Do not clean the coupling ball bar with
a steam-jet or high-pressure jet
cleaner.Interior care
Interior and upholsteryOnly 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.
166Vehicle careCaution
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.
