Fuses and bulbs
CAUTION
● Remo v
e the ignition key before working on
the electric system. Otherwise, a short circuit
could occur.
● Switch off the lights or parking lights be-
fore
you change a bulb. For the sake of the environment
Please ask your specialist retailer how to dis-
pose of u

sed bulbs in the proper manner. Note
● Dependin g on w

eather conditions (cold or
wet), the front lights, the fog lights, the tail
lights and the turn signals may be temporari-
ly misted. This has no influence on the useful
life of the lighting system. By switching on
the lights, the area through which the beam
of light is projected will quickly be demisted.
However, the edges may continue to be mis-
ted.
● Please check at regular intervals that all
lighting (es
pecially the exterior lighting) on
your vehicle is functioning properly. This is
not only in the interest of your own safety,
but also that of all other road users.
● Before changing a bulb, make sure you
have the c
orrect new bulb.
● Do not touch the glass part of the bulb with
your bar
e hands, use a cloth or paper towel
instead. The residue left by the fingerprints
would vaporise as a result of the heat gener- ated by the bulb, they will be deposited on
the refl
ect

or and will impair its surface.
● Depending on the level of equipment fitted
in the vehic
le, LEDs may be used for part or
all of the interior and/or exterior lighting.
LEDs have an estimated life that exceeds that
of the vehicle. If an LED light fails, go to an
authorised workshop for its replacement. Change the front bulbs

Instruments and warning/control lamps
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 278. 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 42 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 level
Fig. 128
Fuel gauge. The display

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 117. When the fuel level is very low,
the lower diode flashes in red.
The fuel range is displayed on the instrument
panel ››› Fig. 125 3 .

lamp will light up or flash and will be accom-
panied by three audible warnings. This is a
danger warning. Stop the vehicle and switch
off the engine. Check the fault and correct it.
Obtain professional assistance if necessary.
If several priority 1 faults are detected at the
same time, the symbols will be displayed one
after the other for about 2 seconds at a time
and will continue until the fault is corrected.
No menus will be shown in the display for the

Pollution filter
The pollution filter (a combined particulate
filter and active carbon filter) serves as a bar-
rier against impurities in the outside air, in-
cluding dust and pollen.
For the climate control system to work with
maximum efficiency, the pollution filter must
be replaced at the specified intervals in the
Maintenance Programme.
If the filter loses efficiency prematurely due
to use in areas reaching very high pollution
levels, the pollen filter must be changed
more frequently than stated in the Service
Schedule. WARNING
Reduced visibility through the windows in-
cr e

ases the risk of serious accidents.
● Always ensure that all windows are free of
ice and sno
w, and that they are not fogged, so as to maintain good visibility of everything
outs
ide.
● The m

aximum heat output required to de-
fros
t windows as quickly as possible is only
available when the engine has reached its
normal running temperature. Only drive when
you have good visibility.
● Always ensure that you use the heating
syst
em, fresh air system, air conditioner and
the heated rear window to maintain good visi-
bility to the outside.
● Never leave the air recirculation on for a
long period of time. If
the cooling system is
switched off and air recirculation mode
switched on, the windows can mist over very
quickly, considerably limiting visibility.
● Switch air recirculation mode off when it is
not requir
ed. WARNING
Stuffy or used air will increase fatigue and re-
duce driv er c

oncentration possibly resulting
in a serious accident.
● Never leave the fresh air fan turned off or
use the air rec
irculation for long periods of
time; the air in the vehicle interior will not be
refreshed. CAUTION
● If y

ou suspect that the air conditioner is
damaged, switch it off with the A/C button to prevent further damage and have it checked
by
a s

pecialised workshop.
● Repairs to the air conditioner require spe-
cia
list knowledge and special tools. There-
fore, we recommend you to take the vehicle
to a specialised workshop. Note
● If the humidity and t

emperature outside the
vehicle are high, condensation can drip off
the evaporator in the cooling system and
form a pool underneath the vehicle. This is
normal and does not indicate a leak.
● Keep the air intake slots in front of the
winds
creen free of snow, ice and leaves to en-
sure heating and cooling are not impaired,
and to prevent the windows from misting
over.
● The air from the vents flows through the ve-
hicle int
erior and is extracted by slots in the
luggage compartment designed for this pur-
pose. Therefore, you should avoid obstruct-
ing these slots with any kind of object.
● The air conditioner operates most effective-
ly with the w
indows closed. However, if the
temperature inside the vehicle is excessive
because of the sun, the air inside can be
cooled faster by opening the windows for a
short time.
● Do not smoke while air recirculation mode
is on, a
s smoke drawn into the air condition-
ing system leaves residue on the evaporator,
producing a permanent unpleasant odour. 164

Air conditioning
●
At lo w out
side temperatures, the compres-
sor switches off automatically and cannot be
switched on even with the AUTO button.
● It is advisable to turn on the air condition-
ing at l

east once a month, to lubricate the
system gaskets and prevent leaks. If a de-
crease in the cooling capacity is detected, a
Technical Service should be consulted to
check the system.
● To ensure correct operation, the grilles on
both sides
of the screen must not be obstruc-
ted. ●
When the engine i s

under extreme strain,
switch off the compressor for a moment. Economic use of the air conditioning
When the air conditioning is switched on, the
compr
e

ssor consumes engine power and has
influence on fuel consumption. Consider the
following points in order to have the system
operating in the minimum possible time. ●
If the v

ehicle interior has overheated due to
an excessive solar radiation, it is best to
open the windows or doors to allow the hot
air to escape.
● While in motion, the air conditioning
should not
be switched on if the windows are
open.

Operation
If the engine does not start immediately,
sw it
c
h the starter off after 10 seconds and try
again after half a minute. If the engine still
does not start, the fuel pump fuse should be
checked ››› page 104, Fuses. WARNING
● Never s t

art or run the engine in unventila-
ted or closed rooms. The exhaust gases con-
tain carbon monoxide, an odourless and col-
ourless poisonous gas. Risk of fatal acci-
dents. Carbon monoxide can cause loss of
consciousness and result in death.
● Never leave the vehicle unattended if the
engine is
running.
● Never use “cold start sprays”, they could
explode or c
ause the engine to run at high
revs. Risk of injury. CAUTION
● When the engine i s

cold, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed
more than 50 metr
es to start the engine. Un-
burnt fuel could enter the catalytic converter
and damage it.
● Before attempting to push-start or tow a ve-
hicle in or
der to start it, you should first try to
start it using the battery of another vehicle.
Please observe and follow the notes on the
›››  page 71, How to jump start. For the sake of the environment
Do not warm-up the engine by running the
engine w ith the

vehicle stationary. Start off
immediately, driving gently. This helps the
engine reach operating temperature faster
and reduces emissions. Starting diesel engines
The engine can only be started using a genu-
ine S
EA

T key with its correct code.
– Move the gearbox lever to the neutral posi-
tion and depre s

s the clutch pedal thor-
oughly and hold it in this position for the
starter to turn the engine on.
– Turn the ignition key to position ›››

Glow plug system for diesel engines
To avoid unnecessary discharging of the bat-
tery, do not use any other major electrical
equipment while the glow plugs are pre-heat-
ing.
Start the engine as soon as the glow plug
warning lamp goes out.
Starting a diesel engine after the fuel tank
has run dry
If the fuel tank has been completely run dry,
it may take longer than normal (up to one mi-
nute) to start a diesel engine after refuelling.
This is because the fuel system must elimi-
nate air first. WARNING
Observe the safety warnings ›››
in Starting

engines on page 174. CAUTION
● When the engine i s

cold, you should avoid
high engine speeds, driving at full throttle
and over-loading the engine. Risk of engine
damage.
● The vehicle should not be pushed or towed
