The essentials
Starting Star
t
the engine of the vehicle with the
boosting battery and let it run at idling
speed.
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 Before you remove the jump leads,
switch off the dipped beam headlights if
they are switched on.
Turn on the heater blower and heated
rear window in the vehicle with the flat
battery. This helps minimise voltage
peaks which are generated when the
leads are disconnected.
When the engine is running, disconnect
the leads 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 after about 10 sec-
onds, switch off the starter and try again after
about 1 minute. WARNING

The batt er
y providing assistance must have
the same voltage as the flat battery (12V) and
approximately the same capacity (see imprint
on battery). Failure to comply could result in
an explosion.
● Never use jump leads when one of the bat-
teries
is 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
awa
y from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufact
urer of the jump leads.
● Do not connect the negative cable from the
other vehic
le directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion.
● Never attach the negative cable to fuel sys-
tem component
s or the brake lines in the oth-
er vehicle.
● The non-insulated parts of the battery
clamp
s 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 c
ome into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult
in chemical burns. Note
The vehicles must not touch each other, oth-
erw i
se electricity could flow as soon as the
positive terminals are connected. Changing the windscreen wiper

Periodic maintenance
P eriodic
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. ●
It i s
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 vehicle on a hill with the
clutc
h, use the foot brake or hand brake, us-
ing 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 emis-

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! » 167

– Chec k
th
at the fuel flap is correctly closed.
Vehicles with a keyless fuel cap (the side
flap will unlock using the central locking sys-
tem)
– Once the vehicle has been unlocked using
the central
locking button, press the fuel
flap in the direction of the arrow 1›››
Fig. 202.
– Open the cover in the direction indicated
by
the arr
ow 2 .
– Unscrew the tank cap anti-clockwise and
pl
ac
e it on top of the tank flap ››› Fig. 202
.
– Insert the pump nozzle into the fuel feed
tube as
far as it will go.
The fuel tank is full as soon as the automatic
filler nozzle cuts out ››› .
– Remove the pump nozzle from the fuel feed
tube and p
l
ace it back on the pump.
– Screw the tank cap clockwise until it clicks
into pl
ace.
– Close the tank flap. Make sure you hear it
click
into place.
– Check that the fuel flap is properly closed. WARNING
Observe all relevant statutory regulations on
tran s
porting spare fuel canisters. For safety reasons, we do not recommend carrying a
sp
ar
e canister in the vehicle. The canister
could be damaged in an accident and fuel
may leak. Risk of fire! CAUTION
● Sw itc
h off the auxiliary heater (heater and
independent heater) before filling the tank.
● The fuel tank is full as soon as the automat-
ic fil
ler nozzle cuts out. Do not continue fill-
ing, as this will fill the expansion chamber.
● Never completely empty the tank! An irreg-
ular f
uel supply can cause ignition faults,
which can result in damage to a substantial
amount of engine parts and the exhaust sys-
tem.
● If any fuel is spilt onto the paintwork of the
vehicl
e, it should be removed immediately.
Risk of damage to paintwork! Note
There is no emergency mechanism for the
manua l
release of the fuel tank flap. If neces-
sary, request assistance from specialised per-
sonnel. Note
The fuel tank capacity is around 55 litres, of
which 7 litr e
s are the reserve. Types of petrol
The correct grade of petrol is listed inside the
fuel
t
ank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded pet-
rol. The petrol must comply with European
Standard EN 228 or German standard DIN
51626-1 and must be unleaded. You can re-
fuel with a maximum ethanol proportion of
10 % (E10). The types of petrol are differenti-
ated by their octane rating (RON).
The following titles appear on the corre-
sponding adhesive on the fuel tank flap:
Super unleaded 95 octane or normal 91 oc-
tane unleaded petrol
We recommend you use super 95 octane pet-
rol. If this is not available: normal 91 octane
petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95
octanes
You should use super petrol with a minimum
of 95 octanes.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
