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,
use the foot
brake or hand brake, using the
latter to start. The fuel consumption will be » 201

●
Never c o
ver the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pans
ion tank when the engine is hot. If the
coolant is hot, the cooling system will be
pressurised!
● Protect face, hands and arms by covering
the cap with a l
arge, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, s
uch as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you mus
t use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
● If any work has to be performed when the
engine is
started or with the engine running,
there is an additional, potentially fatal, safety
risk from the rotating parts, such as the drive
belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
engine parts. Danger of death. Before
starting any work remove jewellery, tie
back and cover hair, and wear tight-fit-
ting clothes. –
Never ac c
elerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if the
handbrake is applied. Danger of death.
● If work has to be carried out on the fuel
syst
em or on electrical components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. The vehicle must be
unlocked when this is done, otherwise
the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand. WARNING
If the bonnet is not correctly closed, it could
sud den
ly open while driving leaving the driv-
er without visibility. This could result in a se-
rious accident.
● After closing the bonnet, always check that
it is
properly secured by the locking mecha-
nism in the lock carrier piece. The bonnet
must be flush with the surrounding body pan-
els.
● While driving, if you notice that the bonnet
is not
correctly closed then stop immediately
and close it correctly.
● Only open and close the bonnet when there
is no
body within its range. CAUTION
When topping up service fluids, make sure
not t o mi
stake them. Using the wrong fluids
could cause serious malfunctions and engine
damage! For the sake of the environment
Service fluids leaks are harmful to the envi-
ronment . F
or this reason you should make
regular checks on the ground underneath
your vehicle. If you find spots of oil or other
fluids, have your vehicle inspected in a speci-
alised workshop. Opening the bonnet

The bonnet is released from inside the vehi-
cle.
Before opening the bonnet ensure that the
windscreen wipers are in rest position. WARNING
Hot coolant can scald!
● Never open the bonnet if you see steam,
smoke or c oo
lant escaping from the engine
compartment. 264
Checking and refilling levels
seek medical care immediately. Neutralise
any
ac
id splashes on the skin or clothing
with a soapy solution, and rinse off with plen-
ty of water. If acid is swallowed by mistake,
consult a doctor immediately.
● Fires, sparks, open flames and smoking are
prohibit
ed. When handling cables and electri-
cal equipment, avoid causing sparks and
electrostatic charge. Never short the battery
terminals. High-energy sparks can cause in-
jury.
● A highly explosive mixture of gases is re-
lea
sed when the battery is under charge. The
batteries should be charged in a well-ventila-
ted room only.
● Keep children away from acid and batteries.
● Before working on the electrical system,
you mus
t switch off the engine, the ignition
and all electrical devices. The negative cable
on the battery must be disconnected. When a
light bulb is changed, you need only switch
off the light.
● Deactivate the anti-theft alarm by unlock-
ing the v
ehicle before you disconnect the bat-
tery! The alarm will otherwise be triggered.
● When disconnecting the battery from the
vehicl
e on-board network, disconnect first
the negative cable and then the positive ca-
ble.
● Switch off all electrical devices before re-
connecting the b
attery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire. ●
Never c h
arge a frozen battery, or one which
has thawed. This could result in explosions
and chemical burns. Always replace a battery
which has frozen. A flat battery can also
freeze at temperatures close to 0°C (+32°F).
● Ensure that the vent hose is always connec-
ted to the b
attery.
● Never use a defective battery. This could
cause an e
xplosion. Replace a damaged bat-
tery immediately. CAUTION
● Nev er di s
connect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components.
● Do not expose the battery to direct sunlight
over a lon
g period of time, as the intense ul-
traviolet radiation can damage the battery
housing.
● If the vehicle is left standing in cold condi-
tions f
or a long period, protect the battery
from “freezing”. If it freezes it will be dam-
aged. Warning lamp
It lights up
Alternator fault. The control lamp
lights up when the igni-
tion i s
switched on. It should go out when the
engine has started running.
If the control lamp lights up while driving,
the alternator is no longer charging the bat-
tery. You should immediately drive to the
nearest specialised workshop.
You should avoid using electrical equipment
that is not absolutely necessary because this
will drain the battery.
Checking the battery electrolyte level The electrolyte level should be checked regu-
l
arly
in high-mi
leage vehicles, in hot coun-
tries and in older batteries.
