note ››› .
The c oo

orks when the ignition is
switched on. In order to avoid engine dam-
age, please read the following notes for the
different temperature ranges. Engine cold
If on
ly

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 250. 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*

Operation
●
Addition a
l 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 - Gas level

only work
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
re
serve 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.

Never run the fuel tank completely dry. An ir-

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

Instruments and warning/control lamps
Depending on the model, additional text
me s
s
ages 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 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
hazardous area and could cause severe inju-
ries ››› page 246. CAUTION
Failure to heed the control lamps and text
me ss

ages when they appear may result in
faults in the vehicle. Engine management*
 This warning lamp monitors the engine man-
ag
ement
sy

stem for petrol engines.
The warning lamp  (Electronic Power Con-
trol) lights up when the ignition is switched
on while system operation is being verified. It
should go out once the engine is started.
If there is a fault in the electronic engine
management system while you are driving,
this warning lamp will light up. Stop the vehi-
cle and seek technical assistance.
Engine pre-heating/fault system* The warning lamp lights up to show that the
glo
w p
lug

s are preheating the diesel engine.
The control lamp  lights up
If the control lamp  lights up when the en-
gine is started it means that the glow plugs are preheating. When the warning lamp goes
off, the engine shou

ld be started straight
away.
Control lamp  flashes
If a fault develops in the engine management
system while you are driving, the glow plug
system lamp will flash . Take the vehicle to
a specialised workshop as soon as possible
and have the engine checked. 109

Please note the following when using the
central locking switch to lock your vehicle:
● It is not possible to open the doors or the
rear lid fr
om the outside (for safety reasons,
e.g. when stopped at traffic lights).
● The LED in the central locking switch lights
up when all the door
s are closed and locked.
● You can open the doors individually from
the inside b
y pulling the inside door handle. ●
In the event of
an accident in which the air-
bags inflate, doors locked from the inside will
be automatically unlocked to facilitate access
and assistance. WARNING
● The centr a

l locking switch also operates
when the ignition is switched off and auto-
matically locks all the vehicle doors when the
button  is pressed.
● The central locking switch does not operate
if the v

ehicle is locked from the outside and
the anti-theft security system is switched on.
● Locked doors could delay assistance in an
emergency
, potentially putting lives at risk.
Do not leave anyone, especially children, in
the vehicle. Note
The doors and the tailgate are locked auto-

Childproof lock 3
App lies to vehicles with 5 doors: Fig. 135
Childproof lock on the left hand side
door . The childproof lock prevents the rear doors
fr
om bein
g opened fr

om the inside. This sys-
tem prevents minors from opening a door ac-
cidentally while the vehicle is running.
This function is independent of the vehicle
electronic opening and locking systems. It
only affects rear doors. It can only be activa-
ted and deactivated manually, as described
below:
Activating the childproof lock
– Unlock the vehicle and open the door in
which y

ou wish to activate the childproof
lock.
– With the door open, rotate the groove in
the door usin

g the ignition key, clockwise
for the left hand side doors ››› Fig. 135 and
anti-clockwise for the right hand side
doors.
Deactivating the childproof lock – Unlock the vehicle and open the door
whose chi

ldproof lock you want to deacti-
vate.
– With the door open, rotate the groove in
the door usin

g the ignition key, anti-clock-
wise for the left hand side doors ››› Fig. 135
and clockwise for the right hand side
doors.
Once the childproof lock is activated, the
door can only be opened from the outside. The childproof lock can be activated or deac-
tivated b

y inserting the key in the groove
when the door is open, as described above.
Anti-theft alarm system* Des
cription The anti-theft alarm makes it more difficult to

When does the system trigger an alarm?
The anti-theft alarm siren will be triggered for
about 30 seconds accompanied by sound
and optical (flashing) warning signals and
will be repeated about ten times when the
vehicle is locked and the following unauthor-
ised actions are attempted:
