● Set the air di
s
tribution regulator 3 to the

onfigur
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
evel of comfort.
● 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.

Climatronic automatically maintains a com-

and the blower and air distribution levels.
The system also allows for the effect of sun-

ment.
Automatic operation guarantees maximum

The engine is started when the key is in this

at the same time.
Each time that the vehicle is restarted, the ig-
nition key must be turned to position 1 . The

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

Starting petrol engines

– Let go of the ignition key as soon as the en-
gine s t

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

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

Braking and parking Brakin
g capacity and braking distance The efficiency of the brakes depends directly
on the br
ak
e p
ad wear. This wear depends to a great extent on the conditions under which
the vehic
le is operated and the way the vehi-
cle is driven. If you often drive in town, drive
short distances or have a sporty driving style,
we recommend that you have the thickness
of your brake pads checked by technical serv-
ices more frequently than recommended in
the Maintenance Programme.
If you drive with wet brakes, for example, af-
ter crossing areas of water, on days of heavy
rainfall or even after washing the car, the ef-
fect of the brakes is reduced as the brake
discs are wet or even frozen (in winter): in
this case, the brakes should be “dried” by
pressing the brake pedal several times. WARNING
Longer braking distances and faults in the
brak e sy
stem increase the risk of accidents.
● New brake pads must be run in and do not
have the c
orrect friction during the first
200 km (124 miles). This reduced braking ca-
pacity may be compensated for by pressing
on the brake pedal a little harder, which also
applies when the brake pads have to be
changed further on.
● If brakes are wet or frozen, or if you are
driving on r
oads which have been salted,
braking power may be lower than normal.
● On steep slopes, if brakes are excessively
used, they w
ill overheat. Before driving down
a long steep slope, it is advisable to reduce
speed and change down into a lower gear or range (depending on the type of transmis-
sion).
Thu
s, make use of engine braking and
relieve the brakes.
● Never let the brakes “drag” by applying
light pre
ssure. Continuous braking will cause
the brakes to overheat and the braking dis-
tance will increase. Apply and then release
the brakes alternately.
● Never let the vehicle run with the engine
switc
hed off. The braking distance is in-
creased considerably when the brake servo is
not active.
● If the brake fluid loses its viscosity and is
subj
ected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes.
● Non-standard or damaged front spoilers
coul
d restrict the airflow to the brakes and
cause them to overheat. Before purchasing
accessories please observe the relevant in-
structions ››› page 259, Technical modifica-
tions.
● If a brake system circuit fails, the braking
dist
ance will be increased considerably. Con-
tact a specialised workshop immediately and
avoid unnecessary journeys. Control lamp
