Operation
For vehicles with no coolant temperature
g aug
e, a c
ontrol lamp  appears for high
coolant temperatures ››› page 274. Please
note ››› .
The c oo
l

ant temperature gauge only works
when the ignition is switched on ››› Fig. 124.
In order to avoid engine damage, please read
the following notes for the different tempera-
ture 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.
Normal temperature
If in normal 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
temperat

ure is excessive ››› page 274. 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 43 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 cooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel level - Petrol/Diesel

Instrument panel: petrol/diesel
g aug
e The display
››
› Fig. 125
only works when the
ignition is switched on. When the display rea-
ches the reserve mark, the lower diode lights
up in red and the control lamp  appears
››› page 114. When the fuel level is very low,
the lower diode flashes in red.
The fuel range is displayed on the instrument
panel ››› Fig. 122 3 .
The c ap
ac

ity of the fuel tank of your vehicle is
given in the Technical data section
›››  page 58. 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. 118

Instruments and warning/control lamps
Fuel - Natural Gas level 3 Valid in vehicles equipped with natural gas engine
(GNC)
Fig. 126
Instrument panel: Natural gas gauge The gauges
››
› Fig. 126 and ››› Fig. 125 only
work when the ignition is on. When the dis-
play reaches the reserve mark, the lower LED
lights up in red and the control lamp  ap-
pears. When the fuel level is very low, the
lower diode flashes in red.
● The green warning lamp  ›››
Fig. 126 1 lights up when the vehicle is running in natu-
r
al
g
as operating mode.
● The green warning lamp  1 turns off
when the n at
ur

al gas is exhausted. The en-
gine changes to operate with petrol.
● The yellow control lamp  lights up when
the re
serve level has been reached. Things to note
If the v

ehicle is left parked for a long time im-
mediately after refuelling, the natural gas lev-
el 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 pres-
sure in the gas tank for technical reasons af-
ter a cooling phase just after refuelling.
Control lamps
Warning and c
ontrol lamps Read the additional information carefully
› ›
›

 page 47.
The control and warning lamps are indicators
of warnings, ››› , faults
››
› 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 may be advising of the need for
action ›››
page 114, 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 p

anel.
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 270. CAUTION
Failure to heed the control lamps and text
mes s

ages when they appear may result in
faults in the vehicle. 119
