Driving
exhaust emissions and noise levels all in-
c r
e
ase 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 cross-
ings 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 re-
start the engine.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high dur-
ing 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 con-
sume more than the required amount of fuel.
A well-serviced engine gives you the benefit
of improved fuel efficiency as well as maxi-
mum reliability and an enhanced resale val-
ue.
A badly serviced engine can consume up to
10% more fuel than necessary. Avoid short journeys
To reduc
e the consumption and emission of
polluting exhaust gases, the engine and the
exhaust gas filtration systems should reach
the optimum operating temperature.
With the engine cold, fuel consumption is
proportionally higher. The engine does not
warm up and fuel consumption does not nor-
malise until having driven approximately four
kilometres (2.5 miles). This is why we recom-
mend avoiding short trips whenever possi-
ble.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an ad-
equate pressure saves fuel. If the tyre pres-
sure is just one bar (14.5 psi/100 kPa) too
low, fuel consumption can increase by as
much as 5%. Due to the greater rolling resist-
ance, under-inflation also increases tyre wear
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
Given that every kilo of extra weight will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported. A roof rack is often left in place for the sake
of con
venience, even when it is no longer
needed. At a speed of 100 km/h (62 mph)
and 120 km/h (75 mph) 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 elec-
tricity, fuel consumption also increases. Be-
cause of this, always turn off electrical devi-
ces when you do not need them. Examples of
devices that use a lot of electricity are: the
blower at high speeds, the rear window heat-
ing or the seat heaters*. Note
● If y

our vehicle has Start-Stop, it is not rec-
ommended that you switch this function off.
● It is recommended that you close
the win-
dows when driving at more than 60 km/h
(37 mph).
● Do not drive with your foot resting on the
clutc
h 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.
● Do not hold the car on a hill with the clutch,

Trailer towing Wh at
do
you need to bear in mind
when towing a trailer? Your vehicle may be used to tow a trailer
when fitted w
ith the c

orrect equipment.
If you wish to retrofit a towing bracket, con-
sult ››› page 257.
Connectors
Your vehicle is fitted with a 13-pin connector
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. It is available at any
Technical Service.
Trailer weight/drawbar load
Never exceed the authorised trailer weight. If
you do not load the trailer up to the maxi-
mum permitted trailer weight, you can then
climb correspondingly steeper slopes.
The maximum trailer weights listed are only
applicable for altitudes up to 1000 m above
sea level. With increasing altitude the engine
power and therefore the vehicle 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 re- duced by 10% for every further 1000 m (or
par
t

thereof). The gross combination weight
is the actual weight of the laden vehicle plus
the actual weight of the laden trailer. When
possible, operate the trailer with the maxi-
mum permitted drawbar load on the ball joint
of the towing bracket, but do not exceed the
specified limit.
The figures for trailer weights and drawbar
loads that are given on the data plate of the
towing bracket are for certification purposes
only. The correct towing bracket figures for
your specific model, which may be lower than
these figures, are given in the vehicle docu-
mentation or on ››› page 291, Technical
specifications.
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
The maximum permissible tyre pressure val-
ues are shown on the sticker on the rear part
of the left front door frame. Set the tyre pres-
sure 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 rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear.
Tow rope
Always use a cable between the vehicle and
the trailer ››› page 255.
Trailer rear lights
The trailer's rear lights should comply with
the statutory safety regulations ››› page 255. WARNING
Never transport people in a trailer. This could
re s

ult in fatal accidents. Note
● To w

ing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to to
wing a trailer in your country. 254
