The EDL switches on again automatically as soon as the brake has cooled
down.
Note
•If the ABS warning light comes on, this may also indicate a fault in the
EDL. Please have the vehicle inspected as soon as possible by a Škoda
dealer.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other
assignment of tyres and wheels) can influence the function of the EDL
⇒ page 226.
Brakes
What has a negative effect on braking efficiency?
Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating
conditions of the vehicle and your style of driving. Particularly if you drive
a great deal in towns and over short distances or if you adopt a sporty style of driving, it may be necessary to have the thickness of the brake pads
inspected at a Škoda Dealer between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under
certain conditions such as when driving through water, during heavy rain
showers or after the vehicle has been washed in an automatic vehicle
wash, since the brake discs and brake pads may be moist or even have a
coating of ice on them in winter. You should dry the brakes as soon as
possible (by applying and releasing the brakes several times, if the road
conditions and the traffic situation allows it).
There also may be a certain delay before the full braking efficiency is
available when driving on roads which have been treated with road salt if
you have not used the brakes for some considerable time beforehand.
The layer of salt on the brake discs and brake pads must first be rubbed
off when you apply the brakes.
Corrosion
We recommend cleaning the brake discs by firmly applying the brakes at
a fairly high speed if you do not make much use of the braking system or
if surface corrosion is present
⇒.
Faults in the brake surface
The brake booster operates using vacuum which is only generated
when the engine is running. This is why you should not drive off with
engine switched off!
The brake pedal has to be depressed with a significantly greater force if
the brake booster is not operating because the vehicle has to be towed or
because there is damage to the brake booster, in order to balance out the
missing brake boosting effect.
If you notice that the braking distance has suddenly become longer and
that the brake pedal can be depressed further, it is possible that a brake
circuit of the dual-circuit brake system has failed. Drive, in such cases, to
the nearest Škoda dealer without delay in order to have the problem recti-
WARNING
•Depress the accelerator carefully when accelerating on
uniformly slippery road surfaces, such as ice and snow. The driven
wheels might still spin despite the EDL and affect the stability of
the vehicle - risk of an accident!
•You should always adapt your style of driving to the condition
of road surface and to the traffic situation even when your vehicle
is fitted with EDL. The increased safety offered must not tempt you
to take greater risks than otherwise - risk of an accident!

Driving and the Environment181

Reducing idling
Idling also costs fuel.
It is worthwhile switching off the engine in a traffic jam or when waiting at
a level crossing or at traffic lights with a lengthy red phase. Even after just
30 - 40 seconds you will have saved more fuel than that is needed when
you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal
operating temperature. Wear-and-tear and pollutant emissions, though,
are particularly high in the warming-up phase. This is why you should
drive off right after starting the engine. Do avoid high engine revolutions
at this time, however.
Regular servicing
A poorly tuned engine consumes an unnecessarily high
amount of fuel.
Having your vehicle serviced regularly at a Škoda Dealer enables you to
satisfy one of the requirements for economical motoring even before you
set off on your journey. Keeping your vehicle properly serviced not only
has a positive effect on the safety of your vehicle and maintaining its
value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10%
higher than normal.
The foreseen maintenance work should be undertaken exactly according
to the service plan by a Škoda dealer.
Also check the oil level after refueling. Oil consumption is dependent to
a considerable extent on the load and speed of the engine. Oil consump- tion could be as high as 0.5 litres/1 000 km depending on your style of
driving.
It is quite normal that a new engine has a higher oil consumption at first,
and reaches its lowest level only after a certain running in time. It is there-
fore not possible to correctly assess the oil consumption of a new vehicle
until after you have driven about 5000 km.
For the sake of
the environment
•You can achieve additional improvements in your fuel economy by
using high-lubricity oils.
•Check the ground below your car at regular intervals to detect any
leakages in good time. Please have your vehicle inspected by a Škoda
dealer if you find any stains caused by oil or other fluids on the floor.

Towing a trailer185
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Tyre inflation pressure
Select the tyre inflation pressure on your vehicle for that of “fully laden”,
⇒
page 220. The inflation pressure of the tyres fitted to the trailer adjust
in accordance with the manufacturer's recommendation.
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see
the traffic behind the trailer with the standard rear-view mirrors. Both exte-
rior mirrors 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 head-
lights. Alter the setting as necessary with the aid of the headlight beam
adjuster ⇒page 58.
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 186.
Note
•We recommend that you also have your 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 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 combination.
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
conditions, particularly near accident black spots.
You must always reduce your speed immediately 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, then brake firmly. This will avoid brake jolts
resulting from the trailer wheels locking. Shift down gears in good time

Fuel199
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and
similar products) in diesel fuel.
It is then necessary to have the
fuel filter drained of water by a Škoda
dealer more often than stated in the service schedule if the quality of the
diesel fuel used is poor.
You can find information on refuelling ⇒page 200, “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 51 606 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 standard E 51 606 , can result in damage to the fuel
system.
Operation in winter
Winter-grade diesel fuel
A different grade of diesel fuel is available at filling stations in winter than
during the summer. Using “summer-grade diesel fuel” at temperatures
below 0°C can result in operational problems because the diesel becomes
viscous as a result of paraffin separation.
It is therefore the case that DIN EN 590 prescribes diesel fuel class for
certain periods of the year which can also be purchased at the corre-
sponding time during the year. “Winter-grade diesel fuel” will still operate
properly even at a temperature of -20°C.
It is often the case in countries with different climatic conditions that diesel
fuels available have a different temperature characteristic. Škoda dealers
and filling stations in the country concerned will be able to provide you with
information regarding the diesel fuels available.

Engine oil
Engine oil specifications
The grade of engine oil should be selected in accordance
with precise specifications.
The engine of your vehicle has been factory-filled with a high-grade oil
which you can use throughout the year - except in extreme climatic
regions.
You can mix various oils together with each other when refilling with oil.
This does not, however, apply for models with flexible service intervals
(QG1).
Engine oils are, of course, undergoing continuous further development.
Thus the information stated in this Owner's Manual is only correct at the
time of publication.
Škoda dealers are constantly informed by Škoda Auto about current
changes. This why you should always have engine oil changed by your
Škoda dealer. Engine oil specifications for vehicles with fixed service intervals
(QG2)
Engine oil specifications for models with flexible service intervals
(QG1).
For further information - see Service Schedule.
Caution
Only the above-mentioned oils may be used on vehicles with flexible
service intervals (QG1). We recommend always refilling with oil of the
same specification since this will maintain the properties of the oil. In
exceptional cases, you must top up only once engine oil complying with
Specification VW 502 00 (only for petrol engines) or Specification VW 505
01 (only for diesel engines) to maximum 0.5 litres. You must not use other
engine oils - risk of engine damage!

Inspecting the engine oil level
The dipstick indicates the level of oil in the engine.
Checking the oil level
– Park the vehicle on a horizontal surface.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compart-
ment” on page 203. – Wait a few minutes and pull out the oil dipstick.
– Wipe off the dipstick with a clean cloth and insert it again fully.
– After this, once again withdraw the dipstick and read off the oil
level ⇒page 206, fig. 156 .
Oil level within range
– You must not top up the oil.
Oil level within range
–You may top up the oil. It is possible that the oil level may then
be within range after doing this.
Oil level within range
–You must top up the oil ⇒page 207. It is sufficient, once this
is done, to keep the oil level is within range .
It is normal for the engine to consume oil. The oil consumption may be as
much as 0.5 l/1 000 km depending on your style of driving and the condi-
tions under which you operate your vehicle. The oil consumption may be
slightly higher than this during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably
every time after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range if the engine
has been operating at high loads, for example during a lengthy motorway
trip during the summer months, towing a trailer or negotiating a high
mountain pass, but not above this .
The warning light in the instrument cluster will indicate whether the oil
level is too low ⇒page 28. In this case, check the oil level as soon as
possible. Top up with an appropriate quantity of oil.

Caution
The oil level must on no account extend beyond the range . Danger of
damaging the catalytic converter.
Replenishing engine oil
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres
⇒page 205, “Engine oil specifications”.
– Inspect the oil level ⇒page 206.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
Do not continue your journey if for some reason it is not possible under
the conditions prevailing to top up with oil. Switch of the engine and
obtain professional assistance from a Škoda dealer.
The location of the engine oil filler opening is shown in the illustration of
the engine compartment ⇒page 204.
For the sake of the environment
The oil level must on no account be above the range ⇒page 206,
fig. 156 . 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 17.
Caution
You must not pour any additives into the engine oil - risk of engine
damage!
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
dealer.
WARNING
Avoid dripping oil onto hot parts of the engine when topping up will

thorized persons until you dispose of it properly.

Inspecting and Replenishing211
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
– Open the bonnet ⇒ in “Working in the engine compart-
ment” on page 203.
– Pull off the rubber seal ⇒fig. 158 partially away and lift the
cover slightly.
– Inspect the brake fluid level at the reservoir . The level must be between the “MIN” and “MAX” markings. The markings are
indicated on the side of the reservoir.
A slight drop in the fluid level results when driving due to normal wear-and-
tear and automatic adjustment of the brake 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. A situation where the brake fluid level is too low is indi-
cated by the warning light
 lighting up in the instrument cluster
⇒ page 35. You should drive carefully and immediately to the nearest
Škoda Dealer and have the brake system inspected.
Replacing brake fluid
Brake 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. The 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 Skoda Auto. The specifi-
cation for the brake fluid is “FMVSS 116 DOT 4”.
We recommend that you have the brake fluid replaced by a Škoda Dealer
as part of an Inspection Service.
Caution
Brake fluid damages the paintwork of the vehicle.
For the sake of the environment
In view of the problems involved with proper disposal of brake fluid, the
special tools and the professional knowledge required, you should have
the brake fluid replaced by a Škoda dealer.

WARNING
•Using old brake fluid can result in severe stress on the brakes
because of the formation of vapour bubbles in the brake system.
This greatly impairs the braking efficiency and thus also the safety
of your vehicle.
•Brake fluid is toxic! It must therefore be kept safely in closed
original containers and well away from children and unauthorized
persons.
