switched on.
If the cooling system is switched on, the temperature and air humidity drops in the vehicle. The wellbeing of the occupants of the
car is enhanced as a result of this partic-
ularly at high outside temperatures and a
high air humidity. The system prevents the
windows misting up during the cold season of the year. The heating effect is dependent upon the c
oolant temperature, thus
full heat output
only occurs when the engine has reached its operating temperature. It is possible to briefly activate recirculat
ed air mode in order to enhance the cooling
effect
⇒page 104.
The air inlet in front of the windscreen must
be free of ice, snow or leaves in order to
ensure that the heating and cooling systems operate properly. The AC compressor is switched off at a hi
gh coolant temperature in order to provide
cooling at a high load of the engine. After switching on the cooling
Condensation
from the evaporator of the air condi-
tioning may drip down and form a puddle be
low the vehicle. This is quite normal and
not an indication of a leak! Recommended setting for all periods of the year:•
Set the desired temperature, we recommend 22 °C.

•
Move the air outlet vents
3 and
4, so that the air flow is
directed slightly upwards.
WARNING
•
For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin
g. Please familiarize yourself about
how to correctly operate th
e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.•
You should not leave recirculated air mode on over a longer period of time,
as “stale” air may result in fatigue in the driver and occupants, divert your attention and also cause the windows to mist up. The risk of having an accident increases. Switch recirculated air mode off as soon as the windows begin misting up.
Note
•
If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of
deposits. Switch the cooling system on at
least once a month for approximately 5 minut
es at the highest blower stage - also
during the cold season of the year - in order to remove such odours. Also open a window for a short time.•
We recommend that you do not smoke in
the vehicle when the recirculating air
mode is operating since the smoke which is
drawn at the evaporator from the interior
of the vehicle forms deposits in the evapor
ator of the air conditioning system. This
produces a permanent odour when the air conditioning system is operating which can only be eliminated through considerable
effort and expense (replacement of
compressor).•
The used air streams out through the air
removal openings in the luggage compart-
ment.•
On vehicles equipped with a factory-fitted
radio* or navigation*, the information
of the Climatronic is also shown on the display. This function can be switched off, see operating instructions of the ra
dio* or the navigation system*.

Auxiliary heating (auxiliary heating and ventilation)*Description and important information The auxiliary heating (auxiliary he
ating and ventilation) heats or
supplies the interior of the vehicl
e with fresh air independent of the
engine.Auxiliary heating (auxiliary heating) The auxiliary heating (auxiliary heating) functions in connection with the Climatic or Climatronic. It can be used when stationary, when engi
ne is switched off for preheating of the
vehicle as well as while driving (only during the heating phase of the engine). The auxiliary heating (auxiliary heating) wa
rms up the coolant during the combustion
of fuel from the vehicle tank. The coolant warms up the air, which (if the blower speed is not set to zero) flows into the occupant compartment. Auxiliary ventilation The auxiliary ventilation enables fresh air to flow into the vehicle interior by switching off the engine, whereby the interior temperature is effectively decreased (e.g. with the vehicle parked in the sun).

WARNING
•
The auxiliary heating must never be op
erated in closed rooms - risk of
poisoning!•
The auxiliary heating must not be runn
ing during refueling - risk of fire.
•
The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore do not place the vehicl
e, if you wish to operate the auxiliary
heating, in such a way that the exhaust
gases of the auxiliary heating can come
easily into contact with inflammable materi
als (e.g. dry grass) or easily inflam-
mable substances (e.g. fuel run out).
Note
If the auxiliary heating runs, the fuel co
nsumption comes from the vehicle tank. The
auxiliary heating automatically controls the filling level in the fuel tank. If only a low quantity of fuel is present in the fuel tank, the function of the auxiliary heating is blocked.•
The exhaust pipe of the auxiliary heating, which is located on the underside of the
vehicle, must not be clogged and the exhaust flow must not be blocked.•
If the auxiliary heating and ventilation is
running, the vehicle ba
ttery discharges. If
the auxiliary heating and ventilation has be
en operated several times over a longer
period, the vehicle must be driven a few ki
lometers in order to recharge the vehicle
battery.•
The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.•
At low outside temperatures, this can result
in a formation of water vapour in the
area of the engine compartment. This is quite normal and is not an operating problem.•
After switching off the auxiliary heating,
the coolant pump runs for a short period.
•
The auxiliary heating and ventilation does no
t switch on or comes on, if the vehicle
battery indicates a low loading state.•
The auxiliary heating (auxilia
ry heating) does not switch on, if the following was
shown in the information display or before switching off the ignition:
Please refuel!.
.
•
The air inlet in front of the windscreen must
be free of ice, snow or leaves in order
to ensure that the auxiliary heating operates properly.
•
So that warm air can flow in
to the vehicle after switching on the auxiliary heating,
you must maintain the temperature normally selected by you (we recommend 22°C for Climatic, Climatronic and for the heat
ing turn the regulator A to the right
⇒ page 96, fig. 108
). It is recommended to put the air flow in the position
.
•
On vehicles with DPF (diesel particle filt
er) the warm coolant heats up the engine.
Direct switching on/offThe auxiliary heating (auxiliary heating and vent
ilation) can be switched on or off at any
time
directly
using the button on the operating part of the Climatic, Climatronic or
heating
⇒fig. 111
.
If the auxiliary heating and ventilation is not
switched off earlier, it switches off auto-
matically after the expiration of the set operating period, in the menu
Running time
.
Note
A radio remote control for the auxiliary heating can be obtained from Škoda original accessories.

Never leave your vehicle unattended with the engine running.Caution
•
The starter may only be operated (ignitio
n key position ), if the engine is not
running. If the starter is immedi
ately operated after switchin
g off the engine, the starter
or the engine can be damaged.•
Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper
ating temperature - risk of damaging the
engine!•
Vehicles which are fitted with an exhaust gas catalytic converter should not be tow-
started over a distance of more than 50 metres.
For the sake of the environment
Never warm up the engine when the vehicle
is standing. Drive off right away. Through
this the engine reaches its operating temperature more rapidly and the pollutant emis- sions are lower.Petrol enginesThese engines are fitted with a starter system which selects the correct fuel-air mixture for every external air temperature.•
Do not operate accelerator before and when starting engine.
•
Interrupt the attempt at starting after 10
seconds if the engine does not start right
awayand wait for about 30 seconds before repeating the attempt.•
It is possible that the fuse on the electric
al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary
⇒page 233.
•
Contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is
very hot
, to slightly depress the accelerator after
the engine has started.
Diesel enginesGlow plug system Diesel engines are equipped with a glow plug system, the preglow period being controlled automatically in
line with the coolant temperature and outside tempera-
ture. The preglow indicator light
 comes on after the ignition has been switched on.
You should not switch on any major electrical components during the heating period otherwise the vehicle battery
will be drained unnecessarily.
•
You should start the engine immediately after the glow plug warning light
 has
gone out.•
The glow plug warning light will come on for about one second if the engine is at a
normal operating temperature or if the outside temperature is above +5°C. This means that you can start the engine
right away
.

Starting the engine after
the fuel tank has run dry
It may take longer than normal to start the
engine after refuelling if the fuel tank has
run completely dry - up to one minute. This is
because the fuel system must first of all
be filled while the attempting to start the engine.Switching off the engine– The engine can be switched off by turnin

•
The brake booster only operates when
the engine is running. Greater phys-
ical effort for braking is required when en
gine is switched off. Because if you do
not stop as normal, this can cause an accident and severe injuries.
Caution
you should not switch the engine off right
away at the end of your journey after the
engine has been operated for a lengthy period
at high loads but should be allowed it
to run at idling speed for
about 2 minutes. This prevents any accumulation of heat
when the engine is switched off.
Note
•
The radiator fan may continue running fo
r a further 10 minutes or so after the
engine and the ignition have been switched
off. The coolant fan may, however, also
switch on again after some time if the co
olant temperature rises because of an accu-
mulation of heat in the engine or if the engine is warm and the engine compartment is additionally heated
by strong sunlight.
•
This is why particular care is required
when carrying out any work in the engine
compartment
⇒page 204, “Working in the engine compartment”.
Shifting (manual gearbox)
Shift into reverse only when the vehicle is
stationary. Depress the clutch pedal and hold
it fully depressed. Wait a mo
ment before engaging reverse gear in order to avoid any
shift noises. The reversing lights will come on once reverse gear is engaged, provided the ignition is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
•
One should not lay the hand on the shift lever while driving the vehicle. The pres-
sure of the hand will be transferred to the gearshift forks in the gearbox. This can, over a period of time, lead to earl
y wear of the gearshift forks.

Depress the clutch pedal fully when changi
ng gears, in order to avoid unnecessary
wear and damage.HandbrakeApplying the handbrake– Pull the handbrake lever up fully.

⇒page 192.
Note
•
We recommend that you also have your
vehicle inspected between service inter-
vals if you tow a trailer frequently.•
The handbrake on the towing vehicle must be put on when coupling and decou-
pling the trailer.Driving Tips Particular caution is required when towing a trailer.– Do not, as far as possible, drive with
your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to
downhill sections.
– Apply the brakes in good time. – Keep a check on the coolant temperature gauge if the outside temperature is high. Distribution of weight The distribution of the weight
is very poor if your vehicle
is unladen and the trailer is
laden. Maintain a particularly low speed if you cannot avoid driving with this combina-tion. Driving speed Do not drive faster than 80 km/hour for safety reasons. This also applies for countries in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination reduces with increasing speed means that the legally allowed speed should not be used when there are unfavourable road, weather or wind cond
itions, particularly near accident black
spots. You must always reduce your speed immediat
ely as soon as you detect even just the
slightest swaying
of the trailer. On no account attempt to stop the trailer from
“swaying” by accelerating. Apply the brakes in good time! If
the trailer is fitted with a
trailer brake
, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting from the trailer wheels locking. Shift down gears in good time before negotiating a downhill section to allow the engine to also act as a brake. Engine overheating Please keep a check on the coolant temperature gauge if you have to negotiate a lengthy slope in a low gear at a high engi
ne speed when the outside temperature is
very high
⇒page 17, “Coolant temperature gauge”.
If the needle of the coolant temperature gauge moves into the right-hand area or even the red area of the scale, reduce your speed immediately. Stop and switch off the engine if the warning light
 in the instrument cluster begins flashing. Wait a few
minutes and check the level of coolant in the coolant expansion bottle
⇒page 207,
“Inspecting the coolant level”. Please refer to the following guidelines
⇒page 34, “Coolant temperature/ Coolant
quantity
”.
The coolant temperature can be reduced by switching on the heating.Any increase in the cooling effect of the coolant fan through shifting down a gear and increasing the engine speed is not possible
since the fan speed is independent of the
engine speed. One should also not drop a gear
for this reason when towing a trailer as
long as the engine can manage th
e slope without any drop in speed.
