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 286. CAUTION
● To en
sure 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 34 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 cooling air when the vehicle is moving. If the spoiler is damaged this can re-
duc
e the c
ooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel level

the ignition is switched on. When the display
reaches the reserve mark, the lower diode
lights up in red and the control lamp ap-
pears ››› page 102. When the fuel level is very
low, the lower diode flashes in red.

The capacity of the fuel tank of your vehicle is
given in the Technical data section
››› page 48. CAUTION
Never run the fuel tank completely dry. An ir-
r e
gular 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
W arnin
g and control lamps Read the additional information carefully

The control and warning lamps are indicators
of warnings, ››› , faults
››
› or certain func-
tion s.
Some control 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 102, 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.
