GENERAL MAINTENANCE
Care of carRegular, professional care is a way of re-
taining the value of your car.
In addition, it may also be one of the re-
quirements for a warranty claim in the event
of possible corrosion damage and paint
defects on the body.
The care products required are available
as Original Accessories from Škoda. Al-
ways follow the instructions for use stated
on the packaging.Warning

If misused, car care products can
be harmful to health.

Car care products should always
be stored in a safe place where they
are out of the reach of children.
When buying car care products, al-
ways select products which have
been designed to minimize pollution of the environment. Do not dispose of carcare products in domestic refuse.
Fuel filter preheater
The car is equipped with a fuel filter pre-
heater. This ensures proper operation of the
fuel system down to about -25 °C when
using winter-grade diesel fuel which is re-
sistant to temperatures down to -15 °C.
Should the engine no longer start at tempe-
ratures below -25 °C, it is sufficient to park
the car for a certain time in a heated area.
Fuel additives (flow improvers) and simi-
lar products must not be added to the
diesel fuel.
Use only fuel, which complies with offi-
cial standards. Even refueling only once
with fuel which does not comply with of-
ficial standards can lead to damage in
the fuel system.
Biodiesel (PME1 fuel) conforming to
DIN EN 14 214
1)
Cetane number at least 49
Vehicles with diesel engines can also be
operated with biodiesel. The term biodiesel
specifies methyl ester from rape oil, which
must comply with the requirements of the
standard DIN EN 14 214
1).
Warning
Filling the tank even only once with
biodiesel, which deviates from the
standard DIN EN 14 2141), can lead to
damage in the fuel system. Particular features of PME fuel
Biodiesel is manufactured from vegetable
oil using a chemical process.
Biodiesel is sulphur-free which is why no
sulphur dioxide (SO
2) is released when it
is combusted.
The exhaust gas contains less
- carbon monoxide (CO)
- hydrocarbons (HC)
- particulates (e.g. soot)
than when the engine is operated with a
conventional diesel fuel.
If biodiesel is used, the vehicle performance
may be slightly lower and, on the other hand,
fuel consumption may be slightly higher.
Biodiesel is biologically degradable.
PME fuel according to DIN EN 14 214
1) can
be mixed in any desired ratio with diesel
fuel conforming to DIN EN 590.
Driving in winter
PME fuel is suitable for use in winter only
down to -10 °C.
Fuel additives (flow improvers) and simi-
lar products must not be added to the
biodiesel fuel.

GENERAL MAINTENANCE
Changing engine oilThe engine oil should be changed at the
intervals stated in the Service Schedule or
in the service interval display.Warning

Only carry out the engine oil chan-
ge, if you have the required profes-
sional knowledge!

Read and observe the warning
notes before working in the engine
compartment - see page 137.

Let the engine cool down - risk of
burning from hot oil.

Wear an eye protection - risk of
caustic burns due to oil splashes.

Oil is toxic! Store old oil in a safe
place out of the reach of children and
unauthorised persons until you dis-
pose of it properly.

You must not pour any additives
into the engine oil - risk of engine
damage! Damage, which results from
such product, is excluded from the
warranty.
Power steeringInspecting hydraulic fluid level
The reservoir for the hydraulic fluid of the
power steering is located in the right of the
engine compartment.
The hydraulic power steering system is
filled with hydraulic fluid G 002 000.
The hydraulic fluid level is checked when
the engine is at operating temperature and
switched off.
After your skin has come in contact with the
oil, you must thoroughly wash your skin.
On no account dispose of oil in the sewage system or into the ground.
Because of the disposal problem, the special tools and the specialist knowl-edge required, it is best to have the en-gine oil and filter change carried out by
a Škoda Dealer.

142GENERAL MAINTENANCECooling system
In normal operating conditions the cooling
system requires practically no mainte-
nance. The coolant consists of water and
a 40 % concentration of coolant additive.
This mixture not only offers the necessary
antifreeze protection down to -25 °C, but
also protects the cooling and heating sys-
tem from corrosion. In addition, it prevents
the formation of scale and increases the
boiling point of the coolant.
For this reason, the concentration of cool-
ant should also not be reduced during the
summer or in warm countries by topping up
with water. The coolant additive concen-
tration should be at least 40 %.
If greater antifreeze protection is required
for climatic reasons, the concentration of
coolant additive can be increased, but only
up to 60 % (antifreeze protection down to
about -40 °C). A higher concentration re-
duces the antifreeze protection and the
cooling efficiency is also impaired.
Cars for export countries with a cold climate
(e.g. Sweden, Norway, Finland) are factory-
filled for antifreeze protection down to about
-35 °C.
CoolantThe cooling system is factory-filled with the
coolant TL 774-F (G12 PLUS), lilac in col-
our.
We recommend using the same fluid for
topping up the system - G 12 PLUS (lilac
in colour).
In the event that it is necessary to top up
the system with a different coolant or if there
are any unclear aspects, please contact
your Škoda Dealer.
The correct coolant is available from your
Škoda Dealer.
Other coolant additives may consider-
ably impair the corrosion protection pro-
vided.
Any corrosion damage arising from the
use of another additive may result in a
loss of coolant and consequently in
major engine damage.
The fluid level should always be between
the „MAX“ and „MIN“ markings. If the level
has dropped below the „MIN“ marking, the
power steering should be inspected by a
Škoda Dealer. It is not sufficient simply to
top up the hydraulic fluid.
Note
When the engine is not running (e.g. when
the car is being towed or the ribbed belt is
broken) the power steering does not oper-
ate. The car can still be fully steered how-
ever, although greater physical effort is re-
quired for steering.
