Solar-powered blower/solar roof*
If the vehicle is parked in su fficiently strong sunlight, the
blower will operate in solar-powered mode when the ignition
is switched off.After the ignition is switched off, the blower is supplied with electrical power
from the solar roof. Please ensure that outlets 3 and 4 are open ⇒page 159,
fig. 135 to ensure the best possible ventilation.
The blower only works when the sun roof is closed or tilted open at the rear.
If the air recirculation mode is on when you switch off the engine, the climate
control will automatically switch to fresh air ventilation.Supplementary heating*Diesel vehicles are fitted with supplementary heating
2) to raise the tempera-
ture of the interior as quickly as possible. At outdoor temperatures below
+5°C and with the engine running, the supplementary heating will switch on
and off automatically depending on the temperature of the coolant.
In order to save fuel, the supplementary heating can be can be switched off
by briefly pressing the button on the climate control.
Seat heating*
The surface and backrest of the front seats can be electrically
heated.Turn thumbwheel or ⇒fig. 136 to switch on and adjust the
heating on the left or right front seats.The heating is switched off when the thumbwheel is set to 0. The temperature
settings range from 1 to 6.

Cruise Control System (CCS)Introduction
The cruise control system allows you to maintain a constant
speed.Using this equipment, any speed over 30 km /h can be kept constant up to the
power output of the engine. This is subject to power output and braking
ability of the engine. This helps to re duce fatigue, especially on long jour-
neys. The indicator light
in the instrument panel li
ghts up when the cruise
control system is operating.
WARNING
For safety reasons, the cruise control system should not be used in dense
traffic or poor road conditions (such as slippery surfaces, heavy rain, loose
grit or gravel), as this could cause an accident.
Caution
On vehicles with a manual gearbox: do not go into neutral if the device is
enabled without previously releasing the clutch, as the engine will increase
its revs and, under certain conditions, could break down.
Note
The cruise control cannot maintain a constant speed when travelling down
steep hills. The vehicle tends to accelerate under its own weight. Change
down to a lower gear in good time or use the foot brake to slow the vehicle.

Checking and refilling levels
218tion. The damage caused by the use of these anti-freezes may lead to a loss
of liquid coolant, causing serious damage to the engine.•
The anti-freeze G12++ can be mixed on ly with anti-freeze additives G11,
G12 and G12+.
Checking the liquid coolant level
The liquid coolant level can be checked at a glance.– Switch the ignition off.
– Check the coolant level on liquid coolant expansion tank ⇒fig. 167. When the engine is cold, it should be between the
“min” and “max” marks. When the engine is hot, it may be
slightly above the “max” mark.Its location is shown in the correspon ding general overview of the engine
compartment. The liquid coolant level should be checked with the engine switched off.
The liquid coolant level is monitored
by a warning lamp in the instrument
panel ⇒ page 77. However, we recommend that it should be checked occa-
sionally.
Liquid coolant losses
Any loss of liquid coolant normally indicates a leak in the cooling system. In
this case the cooling system should be inspected by a specialist garage
without delay. It is not sufficient merely to top up the liquid coolant.
If there are no leaks in the system, a loss of liquid coolant can only occur if
the coolant boils and is forced out of the system as a result of overheating.
Caution
Radiator sealants must not be added to the liquid coolant. Such additives
could seriously impair the function of the cooling system.Topping up the liquid coolant
Be careful when topping up with liquid coolant.– Switch the engine off.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒fig. 167 with a cloth, an d
carefully unscrew the cap anti-clockwise ⇒ .
– Add liquid coolant.
– Screw on the cap tightly.

Significant tyre pressure lossThe tyre symbol
is displayed and indicates that the tyre pressure for a least
one tyre is insufficient.
- Stop the vehicle.
- Switch the engine off.
- Check the tyre(s).
- Change the wheel if necessary.
Tyre pressure monitoring (RKA+)*
The type pressure monitor display on the instrument panel
indicates that the pressure is too low.The tyre pressure monitoring system makes use of the ABS sensors to
compare the rolling circumference and the frequency characteristics of the wheels. If the rolling cir
cumference or frequency characteristic changes on
one or more wheels, the tyre pressure warning lamp
will light up. The fault
will also be indicated by a warning buzzer. The position of the affected tyre
will also be shown (if only one tyre is affected) on the centre display of the
instrument panel.
The rolling circumference and frequency characteristics can change if:
•
the tyre pressure is too low.
•
the tyre has suffered structural damage.
•
the wheels or the inflation pressures have been changed without initial-
ising the system (see Adjusting the tyre pressure settings).
•
there is a greater load on the wheels of one axle (e.g. if you are carrying
more passengers or luggage).
•
the road surface under the left wheels is different to the road surface
under the right wheels for a long period.
•
when driving with snow chains.
Adjusting the tyre pressure settings (initialising the tyre pressure
monitoring system)
After any incident regarding the wheels of your vehicle, e.g. after modify the
tyre pressure ⇒page 230 or after changing of swapping around wheels ⇒
page 180 - with the vehicle at a standstill and the engine running - press
⇒ fig. 172 . The yellow warning lamp
will light up. Hold the button down
for 2 seconds until the warning lamp goes out and an acoustic warning is
given. You can now release the button.
If the wheels are subjected to extremely stress (e.g. heavy load), the tyre pres-
sure must be increased to the recommended value for the maximum load
(see the adhesive label on the inside of the fuel tank flap) and then initialise
the system.
Tyre pressure warning lamp on
When you switch on the ignition, the tyre pressure warning lamp
will light
up. If the warning lamp flashes and then remains lit after you switch on the
ignition, there is a fault in the system. The instrument panel also display

232Anti-puncture tyres*
Anti-puncture tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.Vehicles equipped with anti-puncture
4) tyres from the factory indi-
cate the loss of tyre pressure on the instrument panel.
Driving with anti-puncture tyres (emergency gear)
– Leave the ESP/TCS (electronic stabilisation programme) switched on, or switch on ⇒page 68.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Look out for the ESP/TCS intervening often, smoke coming from the tyres or the smell of rubber, the vehicle vibrating or a clat-
tering noise. If any of these occur, stop the vehicle.
The anti-puncture tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km and if the circumstances are favourable (for
example, low load), even more.
The damaged tyre should be changed as soon as possible. The rim should be
checked in a specialist workshop to detect possible damage and replace it if necessary. We recommend you contact Technical Service. If more than one
tyre is being used under emergency conditions, this reduces the distance
which can be travelled.
Starting driving in emergency conditions
At the moment the loss of tyre pressure is indicated on the instrument panel,
at least one of the tyres is running in an emergency state
⇒.
End of emergency operation
Do not drive on if:
•
smoke is coming from one of the tyres,
•
there is a smell of rubber,
•
the vehicle vibrates,
•
there is a rattling noise.
When is it no longer possible to co ntinue driving even using anti-puncture
tyres?
•
If the Electronic Stabilisation Program (ESP) is out of operation.
•
If the tyre pressure monitoring system is out of operation.
•
If one of the tyres has been severely damaged in an accident, etc. If a tyre
has been badly damaged there is a risk that parts of the tread can be thrown
off and cause damage to the fuel lines, brake pipes or fuel filler.
•
It is also advisable to stop driving if severe vibrations occur, or if the wheel
starts overheating and gives off smoke.
WARNING
When driving in emergency conditions, the driving quality of the vehicle is
considerably impaired.•
The maximum permitted speed of 80 km/h is subject to road and
weather conditions. Please observe legal requirements when doing so.
•
Avoid sharp turns and rapid manoeuvres, and brake earlier than usual.

FusesChanging fuses
If a fuse has blown, it must be replaced.
– Switch off the ignition and its failed electrical component.
– Remove the fuse cover using a screwdriver ⇒fig. 185 .
– Identify the fuse for the failed component ⇒page 248, “Fuse
assignment”.
– Take the plastic clip from inside the fuse cover, fit it onto the
blown fuse, and pull the fuse out.
– Replace the blown fuse (which will have a melted metal strip) with a new fuse of the same amp rating.
–Fit the fuse cover back on.The individual electrical circuits are pr otected by fuses. The fuses are located
behind a cover at the left-hand end of the instrument panel.
Two spare fuses and a sticker identifying the fuses are provided on the inside
of the fuse cover. There is also a crank handle for operating the sun roof* by
hand (if the electrical system fails).
Caution
Never “repair” damaged fuses and never replace them with fuses with a
higher rating. Failure to comply could result in fire. It could also cause
damage to other parts of the electrical system.
Note
If a newly replaced fuse blows again after a short time, the electrical system
must be checked by a qualified workshop as soon as possible.
