Auxiliary heating (auxiliary heating and ventilation)*Description and important information The auxiliary heating (auxiliary heating 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) f
unctions in connection with the Climatic or
Climatronic. It can be used when stationa
ry, when engine 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)
warms up the coolant during the combus-
tion 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 operated in closed rooms - risk of
poisoning!•
The auxiliary heating must not be running 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
vehicle, if you wish to operate the
auxiliary heating, in su
ch a way that the exhaust gases of the auxiliary
heating can come easily into contact
with inflammable materials (e.g. dry
grass) or easily inflammable su
bstances (e.g. fuel run out).
Note
•
If the auxiliary heating runs, the fuel
consumption comes from the vehicle tank.
Therefore the auxiliary heating should not be operated, if there is very little fuel in the tank.•
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 runni
ng, the vehicle battery discharges.
If the auxiliary heating and ventilation
has been operated several times over a
longer period, the vehicle must be driven a few kilometers in order to recharge the vehicle battery.•
The auxiliary heating only switches the bl
ower 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.

Starting-off and Driving
124
Starting the engineGeneral You can only start the engine only using an original ignition key.•
Place the gearshift lever into neutral (or place the selector lever to the position
P or N in the case of an automatic gearbox)
and put on the handbrake firmly before
starting the engine.•
The clutch pedal should be fully depressed when starting the engine which
means that the starter only has to crank the engine.•
Let go of the key as soon as the engine starts otherwise there may be damage
to the starter. The engine running noises ma
y louder at first be louder for a short time after
starting the cold engine until oil pressure
can be built up in the hydraulic valve
clearance compensation. This is quite no
rmal and is not an operating problem.
If the engine does not start ... You can use the battery of anothe
r vehicle as a jump-start aid
⇒page 252.
It is only possible to tow-start vehicles
fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres
⇒page 256.
WARNING
•
Never run the engine in non ventilat
ed or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon monoxide a poisonous gas - hazard!
Carbon monoxide can cause uncon-
sciousness and death.•
Never leave your vehicle unattended with the engine running.Caution
•
The starter may only be operated (ignition key position ), if the engine is not
running. If the starter is i
mmediately operated
after switching 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 exhaus
t gas catalytic conver
ter 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 vehi
cle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the pollutant emissions 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 befo
re 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 electrical fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary
⇒page 258.
•
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 temper-ature. The preglow indicator light
 comes on after the igniti
on has been switched on.

Technical Data
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 th
e outside temperature is above +5°C. This
means that you can start the engine
right away
.
•
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 diesel
preglow system is defect if the engine
still does not start. Check the fuse and replace it if necessary
⇒page 258.
•
Contact the nearest specialist garage to obtain professional assistance.
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 turning the ignition key from posi-
tion into
⇒
page 123, fig. 146
.
WARNING
•
Never switch off the engine before the
vehicle is stationary - risk of acci-
dent!•
The brake booster only operates when the engine is running. Greater
physical effort for braking is required
when engine 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 yo
ur journey
after the
engine has been operated for a lengthy peri
od 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 conti
nue running for 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
coolant temperature rises because of an
accumulation 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 225, “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 moment be
fore engaging reverse gear in order to
avoid any shift noises.

should be attached to folding arms. Adjust
the mirrors so that they provide you with
an adequate field of view to the rear. Headlights Before starting off with a hitched trailer, also check the setting of the headlights. Alter the setting as necessary with th
e aid of the headlight beam adjuster
⇒ page 63. Detachable ball head The ball rod is detachable on vehicles which feature a factory-fitted towing device. It is stowed together with separate fitting instructions in the spare wheel well in the luggage compartment of the vehicle. Further information on the towing device
⇒page 210.
Note
•
We recommend that you also have yo
ur vehicle inspected between service
intervals if you tow a trailer frequently.•
The handbrake on the towing vehicle
must be put on when coupling and
decoupling 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 temper
ature gauge if the outside temper-
ature 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 combination. Driving speed Do not drive faster than 80 km/hour for safety reasons. This also applies for coun- tries 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
conditions, particul
arly near accident
black spots. You must always reduce your speed immedi
ately 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 down-
hill 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 engine speed when the outside temperature is very high
⇒page 18, “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 yo
ur speed immediately. Stop and switch off
the engine if the warning light
 in the instrument cluste
r begins flashing. Wait a
few minutes and check the level of coolant in the coolant expansion bottle ⇒ page 229, “Inspecting the coolant level”. Please refer to the following guidelines
⇒page 36, “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

Radiator fan The radiator fan may switch on suddenly.The radiator fan is driven by an electr
ic motor and controlled according to the
coolant temperature. The radiator fan may continue running fo
r up to 10 minutes after the engine has
been switched off - even if
the ignition is also off. It
may also switch on suddenly
after a certain time, if•
the coolant temperature has risen beca
use of an accumulation of heat or
•
the warm engine compartment is heated
up additionally by
strong sunlight.
WARNING
You must therefore be aware when work
ing in the engine compartment that
the fan may switch on suddenly - risk of injury!Brake fluidInspecting the brake fluid level
The brake fluid reservoir is located on the left of the engine compartment. The brake fluid reservoir on right-hand steering models is positioned on the other side of the engine compartment. – Switch the engine off. – Open the bonnet
⇒
page 224.
– Inspect the brake fluid level in the reservoir
⇒
fig. 213
. The level must
be between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear and automatic adjustment of the br
ake pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid level drops significantly within a short time or if it drops below the “MIN” marking. If the brake fluid level is too low, this is indicated by the warning light
⇒page 40, “Brake
system
” lighting up in the instru
ment cluster. In this case
stop immediately and
do not drive any further! Obtain professional assistance.
WARNING
•
Read and observe the warning notes
⇒page 225, “Working in the engine
compartment” before working in the engine compartment.•
If the fluid level has dropped below
the MIN marking, do not drive any
further - risk of accident! Obtain professional assistance.Replacing brake fluidBrake fluid absorbs moisture. This causes the fluid to absorb moisture from the surrounding air over a period of time. Excessive water in the brake fluid may be the cause of corrosion in the brake system. Th
e water content also lowers the boiling
point of the brake fluid.
This is why brake fluid must be replaced every two
years. One may only use new genuine brake fluid
from Škoda Auto. The specification for
the brake fluid is “FMVSS 116 DOT 4”.
