12, Fig. 3 only works when the igÂ
nition is switched on. In order to avoid possible
damage to the engine, please read the following
notes for the different temperature ranges.
Engine cold
If the LEDs are still in the lower range of the disÂ
play, this indicates that the engine has not yet
reached operating temperature. Avoid high enÂ
gine speeds, full acceleration and heavy engine
loads.
Normal temperature
The LEDs will settle somewhere in the centre of
the display once the engine has reached operatÂ
ing temperature. If the warning lamp || lights
up in the instrument cluster display, the coolant
temperature is too high

- Additional lights and other accessories in
front of the air inlet reduce the cooling efÂ
fect of the radiator. At high outside temperÂ
atures and high engine loads, there is a risk
of the engine overheating.
- The front spoiler also ensures proper distriÂ
bution of the cooling air when the vehicle is
moving.
If the spoiler is damaged this can
reduce the cooling effect, which could cause
the engine to overheat. Obtain professional
assistance.
® Note
Applies to: vehicles with diesel engine
These engines are so efficient that they may
not reach their full operating temperature in
very cold weather. This is quite normal and no
cause for concern.
Rev counter
The
rev counter indicates the number of engine
revolutions per minute.
The start of the red zone on the dial indicates the
maximum engine speed which may be used briefÂ
ly in all gears when the engine is warm and after
it has been run in properly. However, it is advisaÂ
ble to change up a gear or move the selector levÂ
er to D/S (or
lift your
foot
off
the accelerator) beÂ
fore the needle reaches the red zone. •

Note
After the engine is stopped, the radiator fan
may remain on or turn itself back on for up to
10 minutes, even if the ignition is switched
off. This may occur for the following reasons:
- Residual heat has raised the coolant
temÂ
perature.
- Direct sunlight has additionally heated up
the engine compartment while the engine is
warm.
- Applies to vehicles with diesel particulate
filter: The emission control system is hot
because of the regeneration process, even
though the engine has
not
yet reached operÂ
ating temperature.

® For the sake of the environment
Do not warm up the engine by running it with
the car stationary. You should drive off immeÂ
diately whenever possible. This will help avoid
unnecessary exhaust emissions.
© Note
- Any noises which may be heard when the
engine is started are quite normal and no
cause for concern.
- If
you
leave your vehicle with the ignition
switched on, it will be switched off autoÂ
matically after
a
while. Please note that
electrical equipment such as the exterior
lighting will also be switched off.

speeds of 7 km/h and above. To switch off the
engine, press the ISTART ENGINE STOP| button
twice in quick succession or hold it in for longer
than two seconds.
A WARNING
- Never switch off the engine until the vehicle
is stationary. Otherwise you may not have
the full benefit of the brake servo and powÂ
er steering. You may need more strength to
steer and brake the vehicle than you norÂ
mally would. This would mean a greater risk
of accidents and serious injury, because you
cannot steer and brake in the normal
manÂ
ner.
- Always take the key with you when you Leave
the vehicle. Otherwise the engine can be
started or power-operated equipment such
as the electric windows can be used. This
could result in serious injury.
- When parking, always move the selector
lever to position
P
to prevent the vehicle
from rolling back accidentally.
If the engine has been working hard for
a
long
time,
there is a risk of heat building up in the
engine compartment after the engine has
been switched off; this could cause engine
damage. For this reason, you should leave the
engine idling for about 2 minutes before
switching it off.

Rear carrier systems
When using rear carrier systems (e.g. bicycle
racks) on the towing bracket,
it
is important not
to exceed the maximum load.
The total weight
of
the rear carrier system and
its
load must not exceed
75
kg for this vehicle. HowÂ
ever,
it
is also important to observe the maxiÂ
mum permissible load for the rear carrier sysÂ
tem.
The greater the distance from the towing brackÂ
et, the smaller the maximum permissible Load
on
the rear carrier system. For this reason, you
should secure heavy objects as near as possible
to the towing bracket.
Note the instructions provided by the manufacÂ
turer of the rear carrier system.
Please make sure that the rear carrier system
is
approved for use on your vehicle.
l
Note
A WARNING
The use of an unsuitable rear carrier system
could cause severe damage
to
the towing
bracket. The towing bracket could then break
and cause an accident.
Degrease and clean the ball joint before using
a rear carrier system.

Emission controL
systems
Catalytic converter
Applies to: vehicles with petrol engine
The vehicle must only be used with unleaded petÂ
rol,
otherwise the catalytic converter will be irÂ
reparably damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfirÂ
ing.
This allows unburnt fuel to enter the exhaust
system,
which can cause overheating and damÂ
age to the catalytic converter.
Diesel particulate filter
Applies to: vehicles with diesel engine
The diesel particulate filter can filter out almost
all soot particles contained in the exhaust gas. In
normal driving conditions the filter is self-cleanÂ
ing.
Should the self-cleaning function of the filter
not be able to operate, e.g. when the vehicle is
continuously used only for short trips, the filter
becomes obstructed with soot and the indicator

A WARNING
The exhaust system is very hot when the
vehiÂ
cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission controL system, do not
park the vehicle where the exhaust can
come into contact with flammable materials
under the car (e.g. on grass or at the forest
edge) - risk of fire!
- Do not apply any underseal agents in the
area around the exhaust system - risk of
fire!

- Never pour engine oil down drains or into
the ground.
-Always observe statutory requirements
when disposing of empty oil canisters.
© Note
Depending on
how
you drive and the condiÂ
tions in which the car is used, oil consumption
can be up to 0.5
Itr./lOOO
km. Oil consumpÂ
tion is likely to be higher for the first 5,000

Cooling system
Coolant
The engine cooling system is filled at the factory
with a mixture of conditioned water and coolant
additive. This coolant must not be changed.
The coolant level is monitored by a warning lamp
|
<^page
30. However, we recommend that it
should be checked occasionally.
If you do need to top up the coolant, use a mixÂ
ture of water and coolant additive. We recomÂ
mend mixing coolant additive with distilled waÂ
ter.

© CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling
system - risk of engine damage! In this case,
do NOT drive on. Obtain professional assisÂ
tance.
- Have your qualified workshop check the
cooling system before the winter season to
make sure that the anti-freeze concentraÂ
tion is adequate for the conditions to be exÂ
pected.
This applies particularly if
you
drive
into a colder climate zone.
-To prevent damage to the engine, do not
use a different type of anti-freeze additive if
the approved type of additive is not availaÂ
ble.
In this case use only water and bring
the coolant concentration back up to the
correct level as soon as possible by putting
in the specified additive.
- Always top up with fresh, unused coolant.
- Radiator sealants must not be added to the
coolant.

-If the brake fluid Level is under the MIN
mark, the effectiveness of the brakes and
therefore the safety of the vehicle may be
impaired - risk of accident! Do not drive on.
Obtain professional assistance.
- Heavy use of the brakes may cause a vapour
lock if old brake fluid is left in the system.
This would seriously impair the effectiveÂ
ness of the brakes and the safety of the car
- risk of accident!
