Driving
Maintain the correct tyre pressures
B e
ar in mind th
at 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 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
device
s 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
lower and you will prevent the clutch plate
from being damaged.
● On descents, use the engine brake, chang-
ing to the g
ear that is more suitable for the
slope. Fuel consumption will be “zero” and
the brakes will not suffer. Engine management and ex-

Introduction WARNING
● Bec au
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 ar
ea of the exhaust system: Fire
hazard! Note
While the control lamps , , or re-
m ain lit, ther
e may be engine problems, fuel
consumption may increase and the engine
may lose power. Catalytic converter
To maintain the useful life of the catalytic
c
on
v
erter
– Use only unleaded petrol with petrol en-
gines, as
lead damages the catalytic con-
verter.
– Do not let the fuel get too low in the tank. »

Advice
●
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. 268
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.
– Open the bonnet and open the battery cov-
er at the front

in the en gine c
omp
artment on page 267
››› in Symbols and warnings on handling
the b att
er
y on page 276. For vehicles with
the battery under the spare wheel, open
the rear lid and lift the floor covering. The
battery is located next to the spare wheel.
– Check the colour display in the "magic eye"
on the top of the b
attery.
– If there are air bubbles in the window, tap
the window g
ently until they disperse. »
