With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not regularise until having
driven some
four kilometres. This is the reason why we recommend avoiding
short trips wherever possible.
Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressures are just 1 bar too low, this can put the fuel consumption up 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 through the year: they will increase fuel consump-
tion 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.
Save electrical energy
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 equipment when you do not need them. Examples of equip-
ment that use a lot of electricity are: the fan at high speeds, the rear window
heating or the seat heaters*.
Logbook
A good way of keeping a check on fuel consumption is to take regular notes.
You will be able to note the variations (both positive and negative) and react
accordingly.

Wheels and tyresWheelsGeneral notesAvoiding damage
– If you have to drive over a kerb or similar obstacle, drive very
slowly and as near as possible at a right angle to the kerb.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage (cuts, cracks or blisters, etc.). Remove any foreign objects embedded in the treads.
Storing tyres
– Mark tyres when you remove them to indicate the direction of rotation. This ensures you will be able to install them correctly
when you replace them.
– When removed, the wheels and/or tyres should be stored in a cool, dry and preferably dark location.
– Store tyres in a vertical position if they are not fitted on wheel rims.New tyres
New tyres have to be run in ⇒page 189.
The tread depth of new tyres may vary, according to the type and make of tyre
and the tread pattern. Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibrations or the car pulling to one side, this may indicate that one of the tyres
is damaged. The tyres should be checked immediately by an Authorised
Service Centre.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on tyres with
directional tread. Always observe the direction of rotation indicated when
fitting the wheel. This guarantees optimum grip and helps to avoid aqua-
planing, excessive noise and wear.
WARNING
•
New tyres do not have maximum grip in the first 500 km. Drive particu-
larly carefully to avoid risk of accident.
•
Never drive with damaged tyres. This may cause an accident.
•
If you notice unusual vibration or if the vehicle pulls to one side when
driving, stop the vehicle immediately and check the tyres for damage.
Checking tyre pressure
The correct tyre pressure can be seen on the sticker on the
inside of the tank flap.1. Read the required ty re inflation pressure from the sticker. The
values refer to Summer tyres. For Winter tyres, you must add 0.2
bar to the values given on the sticker.
