automatically. ●
Remov

● Turn the air compressor on with the ON/OFF

● Keep the air compressor running until it
r e
ac
hes 2.0 to 2.5 bar
(29-36 psi/200-250 kPa). A maximum of 8
minutes.
● Disconnect the air compressor.
● If it does not reach the pressure indicated,
uns
crew the tyre inflator tube from the valve.
● Move the vehicle 10m so that the sealant is
dis trib
uted throughout the tyre. ●
Scr ew the c
ompressor tyre inflator into the
valve.
● Repeat the inflation process.
● If the indicated pressure still cannot be
reac
hed, the tyre is too badly damaged. Stop
and request assistance from an authorised
technician.
● Disconnect the air compressor. Unscrew
the tyre infl
ator tube from the tyre valve.
● When the tyre pressure is between 2.5 and
2.0 bars, c
ontinue driving without exceeding
80 km/h (50 mph).
● Check the pressure again after 10 minutes

Driving
engine at high rpm in the lower gears uses
an u nnec
e
ssary amount of fuel.
Manual gearbox: shift up from first to second
gear as soon as possible. We recommend
that, whenever possible, you change to a
higher gear upon reaching 2000 rpm. Follow
the “recommended gear” indication that ap-
pears on the instrument panel
››› page 25.
Avoid 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 in-
crease 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 m
aintenance 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 reduce 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 tyre
s 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 convenience, 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
fan at high speeds, the rear window heating
and the seat heaters*. Note
● If y
ou vehicle has Start-Stop, it is not rec-
ommended to switch this function off. » 163

Useful life of tyres Fig. 213

dic at
or
s. Fig. 214
Location of the tyre pressure sticker. Tread wear indicator
The b
ase of
the side of the original tyres on
your vehicle show 1.6 mm high tread wear in-
dicators ››› Fig. 213. The position of these in-
dicators is given on the tyre sidewalls by the
letters “TWI”, triangular symbols or other
symbols.
The useful life of the tyres depends primarily
on the following factors:
Tyre pressure values
Under-inflation or over-inflation will consider-
ably reduce the useful life of the tyres and
impair the vehicle's handling. Therefore,
check the tyre pressure, including the spare
wheel, at least once a month and before any
long journey.
Inflation pressures for summer tyres are lis-
ted on a sticker inside the fuel tank flap
››› Fig. 214. The pressures for winter tyres are
0.2 bar (2.9 psi/20 kPa) above the summer
values.
Always check the pressure when the tyre is
cold. Do not reduce over-pressure in warm
tyres. The tyre pressures must be altered to
suit notable changes in the load being car-
ried.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (“comfort” tyre pressure). When driving with comfort tyre pressure fuel con-
sumption ma
y increase slightly.
Driving style
Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
Wheel balancing
The wheels on new vehicles are balanced.
Various factors encountered when driving
can cause them to become unbalanced,
which results in vibration of the steering
wheel.
The wheel must be rebalanced if a new tyre is
fitted or if a tyre is repaired.
Incorrect wheel alignment
Incorrect front or rear wheel alignment cau-
ses excessive tyre wear, frequently on one
side, and also impairs vehicle safety. If tyre
wear is very irregular, contact an Official
Service.
Tyre damage
To avoid damage to tyres and wheels, only
drive over kerbs or similar obstacles slowly
and at a right angle if possible.
Check tyres and wheels regularly for damage
(punctures, cracks, blisters, deformities,
etc.). Remove any foreign objects embedded
in outside of the treads.
