ation desired: (towards
the windscreen), (towards the chest),
(towards the footwell) and (towards the
windscreen and footwell areas).
Interior cooling
When the air conditioning is switched on, the
temperature and the air humidity go down.
This way, if the outside humidity is extreme,
the air conditioning prevents the misting of
the windows and therefore, comfort is im-
proved.
● Turn on the cooling system using the
butt
on (the button light turns on).
● Turn the temperature control switch until
the desir
ed interior temperature is reached. ●
Turn the blo
wer switch to any of the set-
tings 1-4.
● Set the air distribution control to the air
flow configur
ation desired: (towards the
windscreen), (towards the chest), (to-
wards the footwell) and (towards the wind-
screen and footwell areas).
Demisting the windscreen
● Turn air distribution to .
● Turn the fan control to one of the two levels
depending on the speed r
equired.
● Rotate the temperature control to the de-
sired l

● Close the central outlets. ●
Open and turn the side outl
ets towards the
windows.
If the air conditioning does not work, this
may be due to the following reasons:
● The engine is stationary.
● The fan blower is switched off.
● The outside temperature is lower than +3°C
(+37°F).
● The air conditioning system compressor
has
been temporarily switched off because of
an increased engine coolant temperature.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air
conditioning c
hecked by a specialised work-
shop.

cally regulates the supplied air temperature
and the blower and air distribution levels.
The system also allows for the effect of sun-
light, so there is no need for manual adjust-
ment.
Automatic operation guarantees maximum
comfort any time of year ››› page 172. Climatronic description

● When you switch on the ignition, control 1›››
Fig. 174 can be u sed t
o set the required in-
terior temperature. It is possible to select interior temperatures
from +16°C
(+64°F) t
o +29°C (+84°F). In this
range the temperature is regulated automati-
cally. If a temperature below +16°C (+64°F) is
selected, “LO” is displayed on the screen. If a
temperature above +29°C (+84°F) is selected,
“HI” is displayed on the screen. At both ex-
tremes, Climatronic works at maximum cool-
ing or heating power, respectively. The tem-
perature is not regulated.
In the event of prolonged, irregular distribu-
tion of the air flow from the outlets (particu-
larly the footwells) and significant differen-
ces in temperature, e.g. on leaving the vehi-
cle, sensitive people may catch cold.
Fan regulation
Climatronic automatically regulates blower
speed according to the interior temperature.
It is possible, however, to set the blower
speed to suit requirements.
● Press the 2 buttons to increase or reduce

be locked.
For the Steering lock to operate without the
ignition key, turn the steering wheel until it
locks with an audible sound. You should al-
ways lock the steering wheel when you leave
your vehicle. This will help prevent vehicle
theft ››› . Switching the ignition or the glow plug sys-

T urn the ignition k
ey to this position and re-
lease it 2 . If the key cannot be turned or it is
diffic u
lt
to turn from position 1 to position
2 , move the steering wheel from one side to
the other; thi s
w
ill release it.
Starting
The engine is started when the key is in this
position 3 . Electrical devices with high pow-
er c on
s
umption are switched off temporarily
at the same time.
Each time that the vehicle is restarted, the ig-
nition key must be turned to position 1 . The
r epetitiv
e s
tart prevention lock of the igni-
tion prevents possible damage to the starter
motor if the engine is already running. WARNING
● The ignition key mu
st NOT be removed from
the lock until the vehicle comes to a stand-
still. Otherwise, the steering could be imme-
diately blocked- Risk of accident!
● Always remove the key from the ignition
when leav
ing the vehicle, even if only for a
short period. This is especially important if
children or disabled people are left alone in
the vehicle. They could accidentally start the
engine or work electrical equipment such as
the electric windows, resulting in an acci-
dent. ●
Uns uper
vised use of the key could start the
engine or any electrical system, such as the
electric windows. This could result in serious
injury. CAUTION
The starter motor will only work when the en-
gine i s s
topped (ignition key position 3 ).
Starting petrol 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 depres
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 the starting posi-
tion ›››
Fig. 175 3 .
– Let go of the ignition key as soon as the en-
gine s t
ar
ts; the starter motor must not run
on with the engine.
After starting a very hot engine, you may
need to slightly press down the accelerator.
When starting a cold engine, it may be a little
noisy for the first few seconds until oil pres-
sure has built up in the hydraulic valve com-
pensators. This is quite normal, and no cause
for concern. »

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 ›››

– Release the ignition key as soon as the en-
gine star
ts. The starter motor should not
turn at the same time.
When starting a cold engine, it may be a little
noisy for the first few seconds until oil pres-
sure has built up in the hydraulic valve com-

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
petro l
engines on page 174. CAUTION
● When the engine i s
cold, you should avoid
high engine speeds, driving at full throttle
