– For
vehicles with Start-Stop system: con-
nect one end of the b
lack jump lead X to a
s uit
abl
e ground terminal, to a solid piece of
metal in the engine block, or to the engine
block itself ››› Fig. 71.
5. Connect the other end of the black jump
l
ead X to a solid metal component bolted
t o the en
gine bloc
k or to the engine block
itself of the vehicle with the flat battery.
Do not connect it to a point near the bat-
tery A .
6. Position the leads in such a way that they cannot
come int
o contact with any moving
parts in the engine compartment.
Starting
7. Start the engine of the vehicle with the boosting b
attery and let it run at idling
speed. 8. Start the engine of the vehicle with the flat
battery
and wait for 2 or 3 minutes until
the engine is running.
Removing the jump leads
9. Before you remove the jump leads, switch off the dipped beam he
adlights if they are
switched on.
10.Turn on the heater blower and heated rear window in the v
ehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
11.When the engine is running, disconnect the lead
s in reverse order to the details
given above.
Make sure the battery clamps have sufficient
metal-to-metal contact with the battery termi-
nals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about a minute. WARNING
● Plea se not
e the safety warnings referring to
working in the engine compartment
››› page 201, Working in the engine
compartment.
● The battery providing assistance must have
the same vo
ltage as the flat battery (12 V)
and approximately the same capacity (see imprint on battery). Failure to comply could
res
u
lt in an explosion.
● Never use jump leads when one of the bat-
teries i
s frozen. Danger of explosion! Even af-
ter the battery has thawed, battery acid could
leak and cause chemical burns. If a battery
freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes
away
from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufactur
er of the jump leads.
● Do not connect the negative cable from the
other vehicl
e directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion.
● Do not attach the negative cable from the
other vehicl
e to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamps
must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot come int
o contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult in c
hemical burns. » 53

Driving
Avoid short journeys
T o r
educ e the c
onsumption 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 conv
enience, 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-
do
ws when driving at more than 60 km/h
(37 mph)
● Do not drive with your foot resting on the
clutch pe
dal, 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,
use the foot br
ake or hand brake, using the
latter to start. The fuel consumption will be lower and you will prevent the clutch plate
from being d
am
aged.
● On descents, use the engine brake, chang-
ing to the ge
ar that is more suitable for the
slope. Fuel consumption will be “zero” and
the brakes will not suffer. Engine management and ex-

gas purification system
Introduction WARNING
● Becau se of
the high temperatures which
can occur in the exhaust purification system
(catalytic converter or diesel particulate fil-
ter), do not park the vehicle where the ex-
haust can come into contact with flammable
materials under the car (e.g. on grass or at
the forest edge). Fire hazard!
● Do not apply wax underneath the vehicle
around the are
a of the exhaust system: Fire
hazard! Note
While the control lamps , , or re-
main lit, ther e m
ay be engine problems, fuel
consumption may increase and the engine
may lose power. 169
