Instruments and warning/control lamps
Low consumption driving status (ECO)*
Depending on the equipment, when driving,
the “ ECO” display appears on the instrument
p anel
when the vehicle is in low consump-
tion status due to active cylinder manage-
ment (ACT ®
)* ››› page 142.
Identify

ing letters on engine (MKB)
Hold the button ››› Fig. 82
4 down for more
than 15 seconds to display the identifying
letters of the vehicle engine (MKB). To do
this, the ignition must be switched on and
the engine switched off. WARNING
Observe the safety warnings ››› in Control
and warning lamps on page 71. WARNING
Even though outside temperatures are above
freezing, some roads and bridges may be icy.
● At outside temperatures above +4°C
(+39°F), even when the “ice crystal symbol”
is not visible, there may still be patches of ice
on the road.
● Never rely on the outside temperature indi-
cator! Note
● Different 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 several 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. Trip recorder

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

The essentials

Operation
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
temperature is excessive ››› page 203. CAUTION
● To ensure 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 77 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-
duce the cooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel level - Gas

2 and

››› Fig. 82 only work when
the ignition i s
switched on. When the display
reaches the reserve mark, the lower diode
lights up in red and the control lamp  ap-
pears ››› page 66. 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 
switches 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.

range
a)
Approximate distance in km that can
still be travelled with the fuel remain-
ing in the tank, assuming the same
style of driving is maintained. This is
calculated using the current fuel con-
sumption.
Journey dura-
tionThis indicates the hours (h) and mi-
nutes (min) since the ignition was
switched on.
Distance cov-
eredDistance covered in km (m) after
switching on the ignition.
CNG quality
Whenever you refuel the quality of the
natural gas is automatically verified
and is displayed when the ignition is
switched on. The display is made in a
percentage of between 70% and
100%. The greater the percentage dis-
played the lower the consumption may
be.
Average speed
The average speed will be shown after
a distance of about 100 metres has
been travelled. Otherwise horizontal
lines are displayed. The value shown is
updated approximately every 5 sec-
onds.

tion steering wheel to store the current speed
and activate the warning.
● If necessary, adjust the desired speed with-
in 5 seconds using the rocker switch  on
the windscreen wiper lever or by turning the
thumbwheel on the multifunction steering
wheel. Next, press the button  or
 again or wait several seconds. The speed is
stored and the warning activated.
● To deactivate it press the button 

wheel
– To view the temperature, press the rocker
button ››› Fig. 87 2 until the main menu
comes up. Enter into Journey data. With the
button 2 move to the oil temperature
gauge.
Vehicles with multifunction steering wheel
– To display the engine oil temperature, enter
the submenu Journey data and turn the
thumbwheel until the oil temperature dis-
play appears.
The engine reaches its operating temperature
when in normal driving conditions, the oil
temperature is between 80°C (180°F)
and
120°C (250°F) . If the engine is required to
work hard and the outside temperature is
high, the engine oil temperature can in-
crease. This does not present any problems
as long as the warning lamps  ›››

Air conditioning
● The air conditioner compressor has been
temporarily switched off because the engine
coolant temperature is too high.
● Another fault in the vehicle. Have the air
conditioner checked by a specialised work-
shop. Special Characteristics
If the humidity and temperature outside the
vehicle are high,
condensation
can drip off
the ev
aporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak! Note
After starting the engine, any residual humid-
ity in the air conditioner could mist over the
windscreen. Switch on the defrost function as
soon as possible to clear the windscreen of
condensation. Air vents
Fig. 140
On the dash panel: air vents Air vents
To ensure proper heating, cooling and venti-
lation in the vehicle interior, air vents
››› Fig. 140 1 should remain open.
● Turn the corresponding thumbwheel (de-
tail) in the required direction to open and
close the air vents. When the thumbwheel is in the

position, the corresponding air vent
i

s closed.
● Change the air direction using the ventila-
tion grille lever.
There are other additional, non-adjustable air
vents in the dash panel 2 , in the footwell
and in the rear area of the interior. Note
Food, medicine and other heat or cold sensi-
tive objects should never be placed in front of
the air outlets as they may be damaged or
made unsuitable for use by the air coming
from the air vents. 127
