120DRIVING TIPS

Do not switch off the ignition when driv-
ing.

Do not overfill engine with oil - see page
140.

Do not tow start vehicle for more than
50 m - see page 179.
Warning
Due to the high temperatures which
can occur in catalytic converters in
very unfavourable conditions, the
vehicle should not be parked in such
a way that the catalytic converter can
come into contact with inflammable
materials.
Note
Even if the emission control system is op-
erating perfectly properly, there may be a
sulphurous exhaust smell in certain engine
operating conditions. This depends on the
sulphur content in the fuel being used.
Quite often this can be remedied by select-
ing another brand of fuel or filling up with
unleaded premium petrol.
Trouble-free operation of the
emission
control system is decisive for environmen-
tally friendly operation of the vehicle.
That is why it is important to note the fol-
lowing points:

Vehicles fitted with a catalytic converter
must only be driven on unleaded petrol -
see page 128.

Never drive until the fuel tank is comple-
tely empty on vehicles fitted with a catalytic
converter. The irregular fuel supply can
cause misfiring. This allows unburnt fuel in-
to the exhaust system which can cause
overheating and damage to the catalytic
converter.

If misfiring, a loss of power and rough
engine running occur when driving, this
may be caused by a fault in the ignition
system. In this case, uncombusted fuel can
get into the exhaust system and thus pass
to the atmosphere. In addition, the catalytic
converter may be damaged as a result of
overheating. Reduce your speed immedi-
ately and have the fault rectified at the near-
est Škoda Dealer. General notes


The wear of the brake pads depends to
a great extent on the driving conditions and
your style of driving. Consequently, it may
also be necessary to have the thickness of
the brake pads inspected at a Škoda Dealer
between the intervals stated in the Service
Schedule, particularly if your car is driven
frequently in towns or over short distances,
or in a very sporty manner.

Change down in good time when driv-
ing downhill, in order to make use of the
engine braking effect. This relieves the
strain on the brake system. When the bra-
kes are applied, do not keep them on con-
tinuously, apply and release the brakes al-
ternately.

Under certain operating conditions, for
example after driving through water, after
heavy rain or after washing the vehicle, the
braking effect may be retarded by wet, or
in winter iced-up brake discs and pads - the
brakes must be dried out first by applying
the footbrake.
Brakes

121
DRIVING TIPS
The full braking effect may also be delayed
when the car has been driven for some time
on heavily salted roads without using the
brakes, because the layer of salt on the
discs and pads has to be removed first.Warning
If a front spoiler, full-size wheel trims
etc., are retrofitted, it is necessary to
ensure that the flow of air to the front
brakes is not restricted - otherwise
the brakes may overheat.
Brake booster
The braking force boosts the pressure,
which you generate with the brake pedal.
The necessary pressure is only generated
when the engine is running. Warning
The brake booster only operates
when the engine is running.
Never switch off the engine before
the vehicle is stationary.
In the case that the brake booster is
not operating - e.g. because the vehi-
cle has to be towed or because there
is damage to the brake booster - the
brake pedal has to be depressed with
a significantly greater force, in order
to balance out the missing brake
boosting effect.Because if you do not stop as nor-
mal, this can cause an accident and
severe injuries.
Brake Assist*
The Brake Assist boosts the brake servo
effect during a brake application in a haz-
ardous situation and is able in this way to
assist the rapid build-up of brake pressure.
In emergency situations the majority of car
drivers do apply the brakes in time, but not
with the brake pedal force which is neces-
sary for achieving maximum deceleration.
Valuable braking distance is lost as a result!The Brake Assist is activated as soon as the
brake pedal is depressed very rapidly. A hig-
her brake servo assistance than is usual in
normal brake applications, is then available.
Consequently, it is possible to build up
within a very short time the brake pressure
which is required for achieving maximum
deceleration with only a correspondingly
slight counterforce on the brake pedal.Depress the brake pedal further for achiev-
ing the shortest possible braking distance. Do
not reduce the foot pressure on the pedal!The Brake Assist is able in this way to help
you in critical situations by building up the
brake pressure more rapidly and shorten-
ing the stopping distance. The advantages
offered by the ABS are fully exploited by the
Brake Assist. As soon as the brake pedal is
released, the Brake Assist function is swit-
ched off then automatically and the usual
service brake function is again available.
Warning

The Brake Assist is also not in a
position to overcome the physical
limits which apply to the braking dis-
tance.

This is something you should re-
member particularly when driving on
smooth or wet road surfaces.

Adapt your style of driving always
to the road condition and the traffic
situation. The increased safety which
the Brake Assist offers you must not
lead you to take any safety risk!

134GENERAL MAINTENANCECleaning engine compartmentWarning
Before carrying out any work in the
engine compartment, it is essential
to read the Notes on page 137.
Good corrosion protection is very important,
particularly in winter when road salts are fre-
quently used. For this reason, the entire en-
gine compartment and the plenum chamber
should be thoroughly cleaned before and af-
ter the winter months and then treated with a
wax preserver so that the road salt cannot
produce any harmful effects.
The ignition must be switched off before
washing the engine.
It is recommended to cover over the al-
ternator before washing the engine com-
partment.
As petrol, grease and oil residues are washed off when cleaning the
engine, the dirty water has to be cleaned in an oil separator. For this reason, anengine wash should only be carried outin a workshop or at a service station (if
these are appropriately equipped).
Škoda Dealers have available the factory-
recommended cleaning and wax treatment
products and are equipped with the nec-
essary facilities.Underbody sealantThe underside of your car is durably protec-
ted against chemical and mechanical influ-
ences.
As it is not possible, however, to totally rule
out the likelihood of the underbody sealant
being damaged from driving, it is recom-
mended to have the protective layer on the
underside of the car touched up at certain
intervals. This is best done before the start
of the winter and in the spring.
Škoda Dealers have available the suitable
sealant products and the equipment nec-
essary and are acquainted with the instruc-
tions for use. For this reason, it is best to
have any touch-up work or additional cor-
rosion protection measures carried out by
your Škoda Dealer.
No underbody sealant should be applied to
the heat shields of the catalytic converter
and to the exhaust pipes because of the
high temperatures in the area of the cata-
lytic converter (risk of fire). It is also not
permitted to remove the heat shields.
Cavity protectionAll the cavities of the vehicle which are at
risk from corrosion are durably protected
before the car leaves the factory.
The cavity protection does not require to
be inspected or touched up. If any wax flo-
ws out of the cavities at high outside tem-
peratures, this can be removed with a plas-
tic scraper. Any stains can be removed with
white spirits.
Pay attention to the relevant safetyand environmental protection regu-
lations if white spirits is used to remove
wax and stains.

138GENERAL MAINTENANCE
LongLife Service*The LongLife Service ensures that your
vehicle is always in proper roadworthy con-
dition while requiring only minimal effort on
your part.
The LongLife Service is determined on the
basis of:
- Oil level and pressure sensor - see page 59
- Brake wear indicator - see page 58
- Engine oils complying with the standard VW 503 00 (petrol engines), VW 506 00
(diesel engines, except PDi engines)
and VW 506 01 (diesel engines) - see
page 138
- Variable service interval display - see page 49
- Battery with so-called „magic eye“ - see page 148.
Further information - refer to Service Sche-
dule. More detailed information is also
available from your Škoda Dealer.
SpecificationThe engine is factory-filled with a brand-
name multigrade oil which can be used as
an all-seasons oil - except in extremely cold
climatic zones. Oils may also be intermixed
when topping up (does not apply to mod-
els with LongLife Service*).
We recommend using oils from the selec-
tion of original oils available at Škoda.
Note
Engine oils naturally also undergo continu-
ous further development. That is why the
information contained in this Owner’s
Manual reflects the technical status at the
time of publication.Engine oil
Škoda Dealers are kept up-to-date by the
factory regarding any changes. It is there-
fore good practice to have the oil change
carried out at a Škoda Dealer.

Warning
Models with variable service intervals (QG1) must only use
the above specified oils. It is recommended for the preser-
vation of the specified properties of the oils conforming to
specification, only engine oil with the same specification
may be used for replenishing. In exceptional cases, only
use engine oil conforming to specification VW 502 00 (only
petrol engines) or conforming to specification VW 505 01
(only diesel engines) for topping up to max. 0.5 ltr. Other
engine oils must not be used - risk of engine damage.
Before a long drive, we recommend that you purchase and
carry with you engine oil which complies with the specifica-
tion for your vehicle. Consequently, you will always have the
correct engine oil for refilling.
We recommend using oils from the range of Škoda Genuine
Oils offered by your Škoda Dealer.
For further information - see Service Schedule.
1)Except PDi engines (engines with unit injection)2)This oil may be used only once for topping up within the specified oil c\

cycle if no approved engine oil is available.

141
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.

145
GENERAL MAINTENANCE
If the fluid level drops significantly within a
short time, however, or if it drops below the
„MIN“ marking, there may be a leak in the
brake system. Insufficient brake fluid level
in the reservoir is indicated by the brake
warning light coming on, see also page 61.
In such a case, contact a Škoda Dealer
without delay and have the brake sys-
tem inspected.
Warning
Read and observe the warning notes
before working in the engine com-
partment - see page 137.
If the fluid level has dropped below
the MIN marking, do not drive any
further - risk of accident! Contact a
Škoda dealer to obtain professional
assistance.
Replacing brake fluidBrake fluid is hygroscopic and conse-
quently absorbs moisture from the sur-
rounding air over the course of time. An
excessive content of water in the brake fluid
can also in the long term be a cause of
corrosion in the brake system. In addition,
the boiling point of the brake fluid is con-
siderably reduced. For this reason, the
brake fluid must be renewed every two
years.
Warning
When the brake fluid becomes too
old, vapour bubbles may form in the
brake system when the brakes are
used hard. The efficiency of the
brakes and thus the vehicle safety is
then seriously affected.
Use only fresh brake fluid conforming with
Specification FMVSS 116 DOT 4, which is
approved by the factory. Warning
Brake fluid is poisonous!
It must therefore only be stored in the
closed original container and, in par-
ticular, out of the reach of children.
Please also note that brake fluid attacks the
paintwork of the car.
Because of the disposal problem, the special tools and specialist
knowledge required, it is best to have the brake fluid change carried out by aŠkoda Dealer.
It is recommended to have the brake fluid
change carried out as part of an Inspec-
tion Service.

150GENERAL MAINTENANCEAfter connecting the battery- restore operation of the convenience sys-tem - see page 16
- set the time - see page 50
- if the radio is protected by a code, set the code - see operating instructions of
car radio
The data of the multifunction display are
erased - see page 50.Replacing batteryIf the battery has to be replaced, the new
battery should have the same capacity, volt-
age (12 volts), amperage, design and have
a plug seal. Škoda Dealers have available
a range of suitable batteries.
Because of the disposal problem in- volved with old batteries, it is best
to have the battery replaced by a Škoda Dealer. Batteries contain substancessuch as sulphuric acid and lead andmust on no account be disposed of in
domestic refuse.
Spark plugsThe spark plugs are replaced as part of the
Škoda Inspection Service.

Should it be necessary to replace the
spark plugs between the Inspection Service
intervals, proceed as follows:Spark plugs and ignition system are matched
to the engine and thus contribute to an ex-
haust with low emission levels.Only the spark plugs selected for the par-
ticular engine should be used in order to
avoid operational problems, engine dam-
age and any infringement of legal require-
ments in respect of emission levels or ra-
dio interference from the spark plugs. Par-
ticularly important aspects are the number
of electrodes, the thermal value and radio
interference suppression.

Spark plugs may also be subject to tech-
nical modifications at short notice. It is
therefore recommended to purchase them
only from Škoda Dealers as they are always
informed of the up-to-date situation.
Ribbed belt
The ribbed belt is one of the components
of the car which is subjected to the most
stress. It is therefore necessary to place
particularly high quality requirements in res-
pect of the belts.

When replacing a ribbed belt, it is not
sufficient to use any ribbed belt of whatever
size. For safety reasons, use only the
ribbed belts selected for your car.

Ribbed belts may also be subject to
technical modifications at short notice. It is
therefore recommended to purchase them
only from Škoda Dealers and to also have
the belts changed there as they are always
informed of the up-to-date situation.
