Observe the safety warnings ›››
in Warning
and contr o
l lamps on page 109. WARNING
Even though outside temperatures are above
freez in

g, some roads and bridges may be icy.
● At outside temperatures above +4°C
(+39°F), even when the “ice c
rystal symbol”
is not visible, there may still be patches of ice
on the road.
● Do not rely on the outside temperature in-
dicator! Note
● Differ ent

versions of the instrument panel
are available and therefore the versions and
instructions on the display may vary. In the
case of displays without warning or informa-
tion texts, faults are indicated exclusively by
the warning lamps.
● Depending on the equipment, some set-
tings
and instructions can also be carried out
in the Easy Connect system. ●
When sever a

l warnings are active at the
same time, the symbols are shown succes-
sively for a few seconds and will stay on until
the fault is rectified. Odometer

les “m”. It is possible to change
the measurement units (kilometres
“km”/miles “m”) in the radio/Easy Connect*.
Please refer to the Easy Connect* Instructions
Manual for more details.
Odometer/trip recorder
The odometer shows the total distance cov-
ered by the vehicle.
The trip recorder shows the distance that has
been travelled since it was last reset. It is used to measure short trips. The last digit of
the trip recor

der indicates distances of 100
metres or tenths of a mile.
The trip recorder can be set to zero by press-
ing 0.0/SET

different temperature ranges.
Engine cold
If only the diodes in the lower part of the
scale light up, this indicates that the engine
has not yet reached operating temperature.
Avoid high revs and heavy acceleration and
do not make the engine work hard. »

Operation
Normal temperature
If in norm
al
operations, the diodes light up
until the central zone, it means that the en-
gine has reached operating temperature. At
high outside temperatures and when making
the engine work hard, the diodes may contin-
ue lighting up and reach the upper zone. This
is no cause for concern, provided the control
lamp  does not light up on the instrument
panel digital display.
Heat range
When the diodes light up in the upper area of
the display and the control lamp appears 
on the instrument panel display, the coolant
temperature is excessive ››› page 266. CAUTION
● To en s

ure a long useful life for the engine,
avoid high revs, driving at high speed and
making the engine work hard for approxi-
mately the first 15 minutes when the engine
is cold. The phase until the engine is warm al-
so depends on the outside temperature. If
necessary, use the engine oil temperature*
›››  page 35 as a guide.
● Additional lights and other accessories in
front of
the air inlet reduce the cooling effect
of the coolant. At high outside temperatures
and high engine loads, there is a risk of the
engine overheating.
● The front spoiler also ensures proper distri-
bution of the c
ooling air when the vehicle is moving. If the spoiler is damaged this can re-
duce the c
oo

ling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel - Gas level

when the ignition is switched on. When the
display reaches the reserve mark, the lower
diode lights up in red and the control lamp 
appears ››› page 104. When the fuel level is
very low, the lower diode flashes in red.
The yellow control lamp  lights up when the
reserve level has been reached.
The green warning lamp  lights up when the
vehicle is running in natural gas operating
mode. The green warning lamp  switc

hes off when
the natural gas is exhausted. The engine
changes to operate with petrol.
Problem: If the vehicle is left parked for a
long time immediately after refuelling, the
natural gas level indicator may not accurately
indicate the same level shown after refuelling
when the vehicle is started up again. This is
not due to a leak in the system, but to a drop
in pressure in the gas tank for technical rea-
sons after a cooling phase just after refuel-
ling.

The c

given in the Technical data section
›››  page 50. CAUTION
Never run the fuel tank completely dry. An ir-
re gu

lar fuel supply could cause misfiring. In
this way the unburned fuel can reach the ex-
haust system, which could cause the catalytic
converter to overheat resulting in damage. Control lamps

 page 40.
The control and warning lamps are indicators

or certain func-
tion s.
Some c
ontrol and warning lamps come
on when the ignition is switched on, and
switch off when the engine starts running, or
while driving.
Depending on the model, additional text
messages may be viewed on the instrument panel display. These may be purely informa-
tive or they m

ay be advising of the need for
action ››› page 104, Instruments.
Depending upon the equipment fitted in the
vehicle, instead of a warning lamp, some-
times a symbol may be displayed on the in-
strument panel.
When certain control and warning lamps are
lit, an audible warning is also heard. WARNING
If the warning lamps and messages are ignor-
ed, the v ehic

le may stall in traffic, or may
cause accidents and severe injuries.
● Never ignore the warning lamps or text
mess
ages.
● Stop the vehicle safely as soon as possible.
● Park the vehicle away from traffic and en-
sure th
at there are no highly flammable ma-
terials under the vehicle that could come into
contact with the exhaust system (e.g. dry
grass, fuel).
● A faulty vehicle represents a risk of acci-
dent for the driv
er and for other road users. If
necessary, switch on the hazard warning
lamps and put out the warning triangle to ad-
vise other drivers.
● Before opening the bonnet, switch off the
engine and al
low it to cool.
● In any vehicle, the engine compartment is a
hazar
dous area and could cause severe inju-
ries ››› page 262. CAUTION
Failure to heed the control lamps and text
mes s

ages when they appear may result in
faults in the vehicle. 109
