Driving and the environmentRunning-inRunning in a new engine
The engine needs to be run-in over the first 1,500 km.Up to 1,000 kilometres
– Do not drive faster than three quarters of top speed.
– Do not accelerate hard.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1000 to 1500 km
–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 fric tion 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, the life of the engine will be increased and its oil
consumption reduced.
Running in tyres and brake pads
New tyres should be run-in carefully for the first 500 km. New
brake pads should be run-in carefully for the first 200 km.During the first 200 km, you can compensate for the reduced braking effect
by applying more pressure to the brake pedal. If you need to make an emer-
gency stop, the braking distance will be longer with new brake pads than with
brake pads which have been run-in.
WARNING
•
New tyres do not give maximum grip to start with, and require running-
in. This may be an accident risk. Drive particularly carefully in the first 500
km.
•
New brake pads must be “run in” and do not have the correct friction
properties during the first 200 km. However, the reduced braking capacity
may be compensated by pressing on the brake pedal a little harder.
Braking effect and braking distance
The braking effect 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

Trailer towingWhat do you need to bear in mind when towing a trailer?Your vehicle may be used to tow a trailer when fitted with the correct equip-
ment.
If the car is supplied with a
factory-fitted towing bracket it will already have
the necessary technical modifications and meet the statutory requirements
for towing a trailer. For the after-market fitting of a trailer towing bracket see
⇒ page 188.
Connectors
Your vehicle is fitted with a 12-pin co nnector for the electrical connection
between the trailer and the vehicle.
If the trailer has a 7-pin plug you will need to use an adapter cable. This is
available from any Technical Service.
Trailer weight / draw bar loading
Never exceed the authorised towing limit. 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
1,000 m above sea level. With increasing altitude the engine power and
therefore 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 combination must be reduced by 10% for
every further 1,000 m (or part thereof).
The gross combination weight is the
actual weight of the laden vehicle plus the actual weight of the laden trailer.
Where possible, operate the trailer with the maximum permitted draw bar
weight on the ball joint of the towing bracket, but do not exceed the specified
limit.
The figures for trailer weights and draw bar weights that are given on the
data 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 ⇒Section
“Technical data”.
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.
Tyre pressure
Set tyre pressure to the maximum permissible pressure shown on the sticker
on the inside of the fuel tank flap. Set the tyre pressure of the trailer tyres in
accordance with the trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. Both exterior mirrors should be mounted on hinged extension
brackets. Adjust the mirrors to give sufficient vision to the rear.
WARNING
Never transport people in a trailer. This could result in fatal accidents.

Note•
Towing a trailer places additional demands on the vehicle. We recom-
mend additional services between the normal inspection intervals if the
vehicle is used frequently for towing a trailer.
•
Find out whether special regulations apply to towing a trailer in your
country.
Ball coupling of towing bracket*Depending on the model version, the spherical head on the trailer hook may
be found in the tool box.
The ball coupling is provided with in structions on fitting and removing the
ball coupling of the towing bracket.
WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and causing
injury.
Note
•
By law, the ball coupling must be removed if a trailer is not being towed
and it obscures the number plate.
Driving tips
Driving with a trailer always requires extra care.Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason it is advisable not to drive at the maximum permissible speed in
unfavourable road, weather or wind conditions. This applies especially when
driving downhill.
You should always reduce speed immediately if the trailer shows the slightest
sign of snaking . Never try to stop the “snaking” by increasing speed.
Always brake in good time. If the trailer has an overrun brake, apply the
brakes gently at first and then firmly. This will prevent the jerking that can be
caused by the trailer wheels locking. Sele ct a low gear in good time before
going down a steep descent. This enables you to use the engine braking to
slow down the vehicle.
Heating
When climbing long hills in hot weather with the engine running fast in a low
gear, you should monitor the coolant temperature gauge ⇒page 55.
Electronic Stabilisation Program*
Do not switch off the ESP* when towing a trailer. The ESP* makes it easier to
stabilise if the trailer starts to snake.

If a towing bracket is to be fitted after the vehicle is purchased, this must be
completed according to the instructions of the towing bracket manufacturer.
The attachment points for the towing bracket are underneath the vehicle.
The distance between the centre of th
e ball coupling and the ground should
never be lower than the measurement indicated when the vehicle is fully
loaded including the maximum resting weight.

Fitting a towing bracket
•
Driving with a trailer implies additional work for the vehicle. For this
reason, before fitting a trailer system, refe r to the Technical Service to find out
if the vehicle cooling system should be adjusted.
•
Observe the legal requirements in yo ur country (e.g. the fitting of a sepa-
rate warning lamp).
•
Certain vehicle componen ts, e.g. the rear bumper must be removed and
reinstalled. The towing bracket securi ng bolts must be tightened using a
torque wrench, and an electrical sock et must be used to connect to the
vehicle's electrical system. This requires specialist knowledge and tools.
•
The figures in the illustration show the dimensions and attachment points
which must be observed if you are retrofitting a towing bracket.
WARNING
Towing brackets should be fitted by specialists.
•
If the towing bracket is incorrectly installed, there is serious danger of
an accident.
•
For your own safety, please observe the instructions provided by the
manufacturer of the towing bracket.Caution
•
If the electrical socket is incorrectly installed, this could cause damage to
the vehicle's electrical system.

– Pull the dipstick out again and check the oil level ⇒ page 198,
fig. 136.
– Replace the dipstick, pushing it in as far as it will go.The position of the dipstick is shown in the corresponding engine compart-
ment diagram ⇒page 252.
If the oil level is in area ⇒page 198, fig. 136 , do not top up with oil.
If the oil level is in area , you may top up with oil (approx. 0.5 l).
If the oil level is in area , you mu st top up with oil (approx. 1.0 l).
It is normal for the engine to consume a certain amount of oil. Consumption
can be up to 1.0 litres per 1,000 km. For this reason the engine oil level must
be checked at regular intervals, prefer ably when filling the tank and before a
journey.
When the engine is working hard, for instance during sustained high-speed
motorway cruising in summer, when towi ng a trailer or climbing on mountain
passes, the oil level should preferably be kept within area and not above
this.
WARNING
Any work carried out in the engine compartment or on the engine must be
carried out cautiously.•
When working in the engine compartment, always observe the safety
warnings ⇒ page 193.Caution
If the oil level is above the area do not start the engine. This could result
in damage to the engine and catalytic converter. Contact an Authorised
Service Centre.
Topping up engine oil

Top up gradually with small quantities of oil.Before opening the bonnet, read and observe the warnings ⇒ in
“Safety instructions on working in the engine compartment” on
page 193 .
– Unscrew cap from oil filler opening ⇒fig. 137.
– Top-up oil in small amounts, using the correct oil.
– To avoid over-filling with engine oil, you should top-up using small quantities, wait a while and check the oil level before
adding any more oil.
– As soon as the oil level is in area , carefully close the cap.The position of the oil filler openi ng is shown in the corresponding engine
compartment diagram ⇒page 252.

General notes on the technical data
250WeightsKerb weight refers to the basic model with a fuel tank filled to 90% capacity
and without optional extras. The figure quoted includes 75 kg to allow for the
weight of the driver.
For special versions and optional equipment fittings or for the addition of
accessories, the weight of the vehicle will increase ⇒.
WARNING
•
Please note that the centre of gravity may shift when transporting
heavy objects; this may affect the vehi cle's handling and lead to an acci-
dent. Always adjust your speed and dr iving style to suit road conditions
and requirements.
•
Never exceed the gross axle weight rating or the gross vehicle weight
rating. If the allowed axle load or the allowed total weight is exceeded, the
driving characteristics of the vehicle may change, leading to accidents,
injuries and damage to the vehicle.
To w i n g a t r a i l e rTrailer weightsTrailer weights
The trailer weights and drawbar loads approved are selected in intensive
trials according to precisely defined criteria. The approved trailer weights are
valid for vehicles in EU for maximum speeds of 80 km/h (in certain circum-
stances up to 100 km/h). The figures may be different in other countries. All
data in the official vehicle documents take precedence over these data ⇒. Drawbar load
The
maximum permitted weight exerted by the trailer drawbar on the ball joint
of the towing bracket must not exceed 75 kg.
In the interest of road safety, we recommend that you always tow
approaching the maximum drawbar load. The response of the trailer on the
road will be poor if th e drawbar load is too small.
If the maximum permissible drawbar load cannot be met (e.g. with small,
empty and light-weight single axle trailers or tandem axle trailers with an axle
base of less than 1 metre), at least 4% of the actual trailer weight is a legal
stipulation for a drawbar load.
WARNING
•
For safety reasons, you should not drive at speeds above 80 km/h when
towing a trailer. This also applies to countries where higher speeds are
permitted.
•
Never exceed the maximum trailer weights or the draw bar loading. If
the permissible axle load or the perm issible total weight is exceeded, the
driving characteristics of the vehicle may change, leading to accidents,
injuries and damage to the vehicle.

The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given there are for cold tyres. The slightly
raised pressures of warm tyres must not be reduced ⇒.
