Fuel
206
„Biofuel (RME rape oil methyl ester fuel) must comply with the DIN
EN 14 214 . Please refer to the following guidelines ⇒page 206,
“Biofuel*”.
„Diesel fuel mixture according to standard CSN 65 6508 from
02/2003 contains diesel fuel according to standard DINEN590 and a
concentration of biofuel (rape oil methyl ester) according to standard
DIN EN 14 214 in the following two concentrations:
„5% share of biofuel RME according to the standard DIN EN 14 214
- Denomination SMN 5,
„30% share of biofuel RME according to the standard
DIN EN 14 214 - Denomination SMN 30.
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and
similar products) in diesel fuel.
If the quality of the diesel fuel is poor, it is then necessary to drain the fuel
filter more often than stated in the Service schedule.
You can find information on refuelling ⇒page 207, “Refuelling”.
Caution
•Use a fuel complying with the standard. Filling the tank even only once,
which does not comply with the standard, can result in damage to the fuel
system.
•Water which has collected in the fuel filter can result in engine
problems.
Biofuel*
Biofuel (methyl ester from rape oil) is manufactured from vegetable oil by
means of a chemical process. Biofuel does not contain sulphur. This means that no sulphur dioxide
(SO
2) is produced when it is burnt.
The exhaust gases contain less
•carbon monoxide (CO),
•hydrocarbons (HC),
•particles (soot)
than when operating with conventional diesel fuel.
The Biofuel is more biodegradable.
When using biofuel pay attention to the following points:
•The Performance may be reduced slightly if you switch to driving with
biofuel.
•The fuel consumption may increase slightly if you switch to driving
with biofuel.
Biodiesel conforming to the standard E 14.214 can be mixed in any
desired ratio with diesel fuel conforming to the standard EN 590.
We recommend refuelling with diesel fuel at temperatures below -10°C.
Caution
•Filling the tank even only once with biofuel, which does not comply with
the standard DIN EN 14 214 , can result in damage to the fuel system.
•It is prohibited to use biofuel (RME) and diesel fuel mixture for diesel
engines with the exhaust standard EU4.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
For the sake of the environment
The oil level must on no account be above the range ⇒page 213. Oil
will otherwise be drawn in through the crankcase ventilation and may pass
through the exhaust system to atmosphere. The oil may combust in the
catalytic converter and damage it.
Changing engine oil
The engine oil must be changed at the intervals stated in the Service
schedule or according to the service interval indicator ⇒page 16.
WARNING
•Only carry out the engine oil change, if you have the required
professional knowledge!
•Read and observe the warning notes ⇒page 210, “Working in
the engine compartment” before working in the engine compart-
ment.
•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 chil-
dren and unauthorized persons until you dispose of it properly.
Caution
You must not pour any additives into the engine oil - risk of engine
damage! Damage, which results from such product, are excluded from the
warranty.
For the sake of the environment
•You must on no account pour oil into the ground or into the sewage
system.
•In view of the problems involved in properly disposing of old oil, the
material, equipment and the knowledge required for such work, we recom-
mend that you have the oil and oil filter change carried out by your Škoda
Service Partner.
Note
After your skin has come in contact with the oil, you must thoroughly wash
your skin.
Cooling system
Coolant
The job of the coolant is to cool the engine.
The cooling system does not require any maintenance under normal oper-
ating conditions. The coolant consists of water with a concentration of
coolant additive of 40 %. This mixture not only provides antifreeze protec-
tion down to -25°C but also protects the cooling and heating system from
corrosion. It also prevents the formation of scale and significantly
increases the boiling point of the coolant.
You must therefore not reduce the concentration of antifreeze agent in the
coolant by adding water, also not during the summer months or in coun-
tries with a warm climate. The concentration of coolant additive in the
coolant must be at least 40%.
