If the
symbol lights up, take the vehicle to a qualified workshop and have
the oil level sensor checked. Until then it is advisable to check the oil level
every time you fill up with fuel ⇒page 232.
Diesel particulate filter obstructed
If the symbol
lights up, you can contribute towards automatic filter
cleaning by driving in the right manner. To do this, drive about 15 minutes in
4th or 5th gear (automatic gearbox: S gear range) at a speed of 60 km/h, with
the engine running at approximately 2000 rpm. The increase in temperature
will burn off any soot in the filter. When cleaning is successful, the symbol
switches off.
If the symbol does not turn off, or the three lamps turn on (particulate

to a qualified workshop to repair the fault.
For further information on the diesel particulate filter, see ⇒page 199.
WARNING
It is essential that you adjust your speed to suit the weather, road, terrain
and traffic conditions. The recommended driving speed must never lead to
the driver disregarding the traffic regulations.

Unlocking and locking
108If the turn signals do not flash, check the doors, the bonnet and the tailgate
to make sure they are properly closed. The turn signals will also flash briefly
if one of the doors or the tailgate or engine bonnet is closed after the alarm
system has been enabled.
LED
When the vehicle is locked, the LED on the top of the driver door trim will flash
rapidly for about 30 seconds and then continue flashing slowly. This is to
indicate that the anti-theft alarm system (including the interior monitoring
and tow-away protection ) is operative. If the LED lights up continuously for
about 30 seconds when the vehicle is locked instead of flashing, this means
the alarm system is not working properly.
Note
•To make sure that the alarm is fully operative when leaving the vehicle,
briefly check that all the doors and windows and the sunroof* are closed.•The alarm is triggered immediately if one of the battery cables is discon-
nected while the alarm system is enabled.
Interior monitoring*
The interior monitoring triggers an alarm if it detects move-
ment inside the vehicle.You should disable the interior monitoring if there is a possibility
that the alarm could be triggered, e.g. by a pet or by an object
moving inside the vehicle ⇒. The tow-away protection feature,
which is integrated into the alarm system, should be disabled if the
vehicle is being towed or transported (e.g. by rail or ship).
Deactivating the interior monitoring
– Open the door and pull out the switch (with the symbol

Air conditioning
162Air conditioning2C-ClimatronicDescription
The air conditioner is designed to automatically keep the
passenger compartment at the temperature you find most
comfortable at all times of the year.Recommended settings:
– Set the temperature to 22 °C (71 °F).
–Press the button ⇒page 164, fig. 141 .The following setting quickly provides a comfortable temperature inside the
vehicle. We therefore recommend you do not modify the setting unless you
find this temperature uncomfortable or where circumstances require as such.
The air conditioner provides heating and ventilation and also cools and dehu-
midifies the air inside the vehicle.
The air conditioner is fully automatic and will constantly maintain the temper-
ature which has been set. To achieve this, the temperature of the air supplied
to the interior, the blower speed (volume of air delivery) and the air distribu-
tion are regulated automatically. The system also takes solar radiation into
account and, therefore, no subsequent manual readjustments are required.
Therefore, automatic mode ⇒ page 165 should be used for the comfort of all
the passengers in virtually all conditions throughout the year.
Please note the following points:
The humidity of the air is automatically reduced when the system cools the
interior of the vehicle. This helps to prevent condensation on the windows. If the humidity and temperature outside the vehicle are high,
condensation
can drip off the evaporator in the air cooling system and form a pool under-
neath the vehicle. This is normal and does not indicate a leak.
If the outside temperature is low, the blower normally only switches to a
higher speed once the coolant has warmed up sufficiently (this does not
apply to the defrost setting).
In order to achieve maximum engine power, the air conditioner compressor is
temporarily switched off when pulling away from standstill with full throttle.
The compressor also switches off if the coolant temperature is excessively
high to ensure adequate engine cooling under extreme loads.
Pollution filter
The pollution filter (a combined particulate filter and activated charcoal filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
element must be replaced at the intervals specified in the Service Plan.
If the vehicle is driven in areas with a high level of air pollution and the filter
is no longer fully effective, it may be necessary to change the filter element
more frequently.
Caution
•If you suspect that the air conditioner system is damaged, switch over to
ECON mode to prevent further damage and have the system checked by a
qualified workshop.•Repairs to the air conditioner require specialist knowledge and special
tools. For this reason, please contact a qualified workshop if the system is not
working properly.

Intelligent technology
196Power steeringPower steering makes it easier to turn the steering wheel
when the engine is running.Power steering assists the driver by reducing the force needed to turn the
steering wheel.
Power steering does not work if the engine is off. In this case the steering
wheel requires much more force to turn.
If the steering is held at its turning limit when the vehicle is stationary, this
will place an excessive load on the power steering system. Turning the
steering wheel to its limit places a load on the system, which causes noise. It
will also reduce the idling speed of the engine.
Caution
When the engine is running, do not turn the steering wheel to its limit for
more than 15 seconds. Otherwise, there is a risk of damaging the power
steering.
Note
•If the power steering should fail at any time or the engine is switched off
(for instance when being towed), the vehicle can still be steered. However,
more effort will be required to turn the steering wheel.•If the system is leaking or malfunctioning, please take the vehicle to a
qualified workshop as soon as possible.•The power steering system requires a special hydraulic fluid. The fluid
reservoir is located at the front of the engine compartment on the left
⇒ page 301. The correct fluid level in the reservoir is important for the power
steering to function properly. The hydraulic fluid level is checked at the
Inspection Service.
Servotronic*The servotronic system electronically adjusts the power
assisted steering.In vehicles equipped with servotronic power steering the degree of power
assistance ⇒page 196 is adjusted electronically according to road speed.
If a fault should occur in the servotronic system, the power steering will still
operate. The degree of power assistance will, however, no longer adapt to
different speeds. If the electronic regulating system is not working properly,
this is most noticeable when turning the steering wheel at low speeds (for
instance when parking), as more effort will be required than usual. The fault
should be corrected by a qualified workshop as soon as possible.

Driving and the environment197
Safety First
Operating Instructions
Practical Tips
Technical Specifications
Driving and the environmentRunning-inRunning in a new engine
The engine needs to be run in over the first 1500 km.Up to 1000 kilometres
– Do not drive at speeds of more than 2/3 the maximum speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 to 1500 kilometres
– Speeds can be gradually increased to the maximum road speed
or maximum permissible engine speed (rpm).During its first few hours of running, the internal friction in the engine is
greater than later on, when all the moving parts have bedded in.
For the sake of the environment
If the engine is run in gently, its life will be increased and its oil consumption
reduced.
Braking capacity and braking distance
The braking capacity and braking distance are influenced by
driving situations and road conditions.The efficiency of the brakes depends directly on the brake pad wear. The rate
of wear of the brake pads depends to a great extent on the conditions under
which the vehicle is operated and the way the vehicle is driven. If you often
drive in town traffic, drive short distances or have a sporty driving style, we
recommend that you have the thickness of your brake pads checked by an
Authorised Service Centre more frequently than recommended in the Ser vice
Plan.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the vehicle, the effect of the brakes is
lessened as the brake discs are wet or even frozen (in winter). In this case the
brakes should be dried by pressing the brake pedal several times.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.•New brake pads must be run in and do not have the correct friction
during the first 200 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also
applies when the brake pads have to be changed further on.•If brakes are wet or frozen, or if you are driving on roads which have
been salted, braking power may be lower than normal.•On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed and

Driving and the environment
200Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly at
higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at level
crossings or at traffic lights with a long red phase. The fuel saved after only
30 - 40 seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a very long time to warm up when it is running at idling
speed. Mechanical wear and pollutant emissions are also especially high
during this initial warm-up phase. It is therefore best to drive off immediately
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maximum
reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressure is just 1 bar too low, fuel consumption can increase by as much as 5%. Due to the greater rolling resistance, under-inflation also increases
tyre wear
and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120 km/h your vehicle will use about
12% more fuel as a result of the extra wind resistance caused by the roof rack
even when it is not in use.
Save electricity
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical components when you do not need them. Examples of
components that use a lot of electricity are: the fan at high speeds, the rear
window heating or the seat heaters*.
Note
•If you vehicle has Start-Stop, it is not recommended to disconnect this
function.•It is recommended to close the windows when driving at more than 60
km/h•Do not drive with your foot resting on the clutch pedal, as the pressure can
make the plate spin, more fuel will be used and it can burn the clutch plate
lining, causing a serious fault.

Technical Specifications
Trailer towingTrailer towingTe c h n i c a l r e q u i r e m e n t s
The towing bracket must meet certain technical requirements.Your vehicle is intended mainly for transporting passengers and luggage.
However, if suitably equipped, it can also be used to tow a trailer or caravan.
If your vehicle has been factory-supplied with a towing bracket, all of the
necessary technical and legal aspects for trailing towing have been taking
into account during manufacturing.
Your vehicle is fitted with a 13-pole socket for the electrical connection
between the trailer and the vehicle. If the trailer has a 7-pole connector you
can use an adapter cable. This can be purchased at an Authorised Service.
If a towing bracket is to be fitted after the vehicle is purchased, this must be
done according to the instructions of the towing bracket manufacturer
⇒ page 212.
WARNING
If a towing bracket is retrofitted, the installation should be carried out by a
qualified workshop.•Particularly in high outdoor temperatures, it is not possible to drive up
long steep gradients without a suitable cooling system. The engine would
heat up.•Incorrect installation can result in a safety risk!
Notes on towing
There are a number of points which need to be checked before
towing a trailer or caravan.– Observe the maximum permitted trailer weights ⇒page 301.Trailer weight
Never exceed the maximum permitted trailer weight.
If you do not load the trailer up to the maximum permitted trailer weight, you
can then climb correspondingly steeper gradients.
The maximum trailer weights listed are only applicable for altitudes up to
1000 m above sea level. With increasing altitude the engine power and there-
fore the vehicle's climbing ability are impaired because of the reduced air
density. The maximum trailer weight has to be reduced accordingly. The
weight of the vehicle and trailer must be reduced by about 10% for every
subsequent 1000 m (or part thereof). This figure refers to the combined
weight of the (loaded) vehicle and (loaded) trailer.
The figures for the drawbar load that appear on the identification plate of the
towing bracket are for certification purposes only. The correct figures for your
specific model, which may be lower than these figures for the towing bracket,
are given in the registration documents and on ⇒page 294. Also refer to
⇒ page 301.
Distributing the load
Distribute loads in the trailer so that heavy objects are as near to the axle as
possible. Loads carried in the trailer must be secured to prevent them
moving.
