⇒ page 25, “Diesel particle filter*  (diesel engine)”.
WARNING
•The diesel particle filter achieves very high temperatures. Therefore do
not park at points where the hot filter comes into direct contact with dry
grass or other combustible materials - risk of fire!
•Never use additional underbody protection or corrosion-protection
agents for the exhaust pipes, catalytic converters, diesel particle filter or
heat shields. When the engine reaches its operating temperature, these
substances might ignite - risk of fire.
Note
•When using diesel fuel with high sulphur content the life of the diesel particle
filter is clearly reduced. A specialist gara ge will be able to tell you which countries
use only diesel fuel with high sulphur content.

The first 1 500 kilometres and then afterwards
A new engine
The engine has to be run in du ring the first 1 500 kilometres.
Up to 1 000 kilometres
– Do not drive faster than 3/4 of the mamimum speed of the gear in use,
that is 3/4 of the maximum permissible engine speed.
– Do not use full throttle.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1 000 up to 1 500 kilometres
– Increase the power output of the engine gradually up to the full
speed of the gear enga ged, that is up to the maximum permissible
engine revolutions.
During the first operating hours the engine has higher internal friction than later
until all of the moving parts have harm onized. The driving style which you adopt
during the first 1 500 kilometres plays a de cisive part in the success of running in
your car.
You should not drive at unnecessarily high engine revolutions even after the
running-in period is comple te. The maximum permissible engine speed is marked
by the beginning of the red zone on the scale of the revolutions counter. Shift up
into the next higher gear on a vehicle fitted with manual gearbox before the red
zone is reached. Extremely high engine revolutions are automatically governed, by
the way.
For a vehicle fitted with a manual gearbox the converse situation also applies: Do
not drive at engine revolutions which are too low. Shift down as soon as the engine
is no longer running smoothly.
Caution
All the speed and engine revolution figures apply only when the engine is at its
normal operating temperature. Never rev up an engine which is cold, neither when
the vehicle is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a higher gear as
early as possible are ways to minimise fuel consumption and operating noise levels
and protects the environment.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first. You should
take account of this fact for the first 500 kilometres and drive particularly carefully.
New brake pads
Allow for the fact that new brake pads do not achieve their full braking efficiency
until approximately 200 kilometres. New brak e pads must be first “run in” before
they develop their optimal friction force. You can, however, compensate for this
slightly reduced braking force by increasing the pressure on the brake pedal.
This guideline also applies to any new brake pads installed at a future date.
During the running-in period , you should avoid excessive stresses on the brakes.
This includes, for example, violent braking, particularly from very high speeds, and
also when crossing mountain passes.

Catalytic converter
Proper operation of the emission co ntrol system (catalytic converter)
is of major significance for drivin g your vehicle in an environmen-
tally conscious way.
Please refer to the following guidelines:
– For vehicles with petrol engine only refuel with unleaded petrol
⇒ page 181, “Grades of petrol”.
– Never run the fuel tank completely empty.
– Do not switch off the ignition while you are driving the vehicle.
– Do not pour too much oil into the engine ⇒page 188, “Replenishing
engine oil”.
– Do not tow-start the vehicle over a distance of more than 50 metres ⇒page 218, “Tow-starting a vehicle”.
If you drive your vehicle in a country in which unleaded petrol is not available, you
must have the catalytic converter replaced later when driving the vehicle into a
country in which use of a cata lytic converter is mandatory.
WARNING
•In view of the high temperatures wh ich may be produced in the catalytic
converter, one should always park a vehicle in such a way that the catalytic
converter cannot come into contact with easily flammable materials below
the vehicle - a risk of fire!
•Never use additional underbody protection or corrosion-protection
agents for the exhaust pipes, catalytic converters or heat shields. Such
substances might ignite when driving - risk of fire!
Caution
•Vehicles fitted with catalytic converter sh ould never be allowed to let the fuel
tank to run completely empty. An irregular fuel supply can result in poor ignition or misfiring. Unburnt fuel may get into the
exhaust system and damage the catalytic
converter.
•Filling the tank even only once with leaded petrol will result in the catalytic
converter being destroyed.
•If you detect misfiring, a drop in perf ormance or irregular engine running when
driving, reduce your speed immediately and have the vehicle inspected by the
nearest specialist garage. The symptoms described may be caused by a fault in the
ignition system. Unburnt fuel may get into the exhaust system and damage the
catalytic converter.
For the sake of the environment
Even if the exhaust system is operating properly, a sulphur-like exhaust odour may
be produced under certain op erating conditions of the engine. This depends on the
sulphur content of the fuel. It is often sufficient to refuel with unleaded premium-
grade petrol of a different brand or at a different filling station.
Driving in an economical and environmentally
conscious manner
General
Your personal style of driving is a major factor.
Your fuel consumption, any pollution of the environmental and the wear-and-tear
to the engine, brakes and tyres, depend essentially on three factors:
•your personal style of driving,
•the conditions under which your vehicle is operated,
•technical aspects.
You can easily improve your fuel economy by 10 - 15 percent by driving in an
economical way with foresight. This section is intended to provide you with a
number of tips on how to protect the en vironment and at the same time save
money.

Driving and the Environment165
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Avoiding full throttle
Driving more slowly means saving fuel.
Sensitive use of the accelerator will not only significantly reduce fuel consumption
but also positively influence environmental pollution and wear of your vehicle.
You should avoid fully exploiting the top speed of your vehicle wherever possible.
Fuel consumption, pollutant emissions and vehicle noises increase disproportion-
ally at high speeds.
The ⇒fig. 167 shows the ratio of fuel consumptio n to the speed of your vehicle.
You will cut your fuel consumption by half if you only make use three-quarters of
the possible top speed of your vehicle.
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 length y 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 em issions, 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 re
volutions at this time, however.
Regular servicing
A poorly tuned engine consumes an unnecessarily high amount of
fuel.
Having your vehicle serviced regularly at a specialist garge 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 fu el consumption which is 10% higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refueling. Oil consumption is dependent to a consid-
erable extent on the load and speed of the engine. Oil consumption 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 ha s a higher oil consumption at first, and
reaches its lowest level only after a certain running in time. It is therefore not
possible to correctly assess the oil cons umption of a new vehicle until after you
have driven about 5 000 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 regula r intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garge if you find any
stains caused by oil or other fluids on the floor.

Avoid driving short distances
Short distances result in an above-average high fuel consumption.
– Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter mu st first have reached their optimal operating
temperature in order to effectively reduce fu el consumption and pollutant emis-
sions.
The cold engine vehicle consumes approx. 20 - 30 litres/100 km of fuel immediately
after starting. Fuel consumption drops to 15 litres/100 km after just 1 kilometre. The
engine reaches its operating temperat ure (outside temperature and engine
dependent) only after about 4 to 10 kilometres and the fuel consumption then
stabilizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The
⇒ fig. 168 shows the different fuel consumptions for the same distance, on the one
hand at +20°C and on the other hand at -10°C. Your vehicle has a higher fuel
consumption in winter than in summer.
Checking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all times. The
rolling resistance will be increased if the tyre filling pressure is too low. This will not only increase fuel consumption but also
tyre wear and the driving behaviour will
worsen.
Always check the inflation pressure of the tyres when cold.
Do not drive with winter tyres all year round for this costs about 10 % more fuel.
Winter tyres are also louder.
No unnecessary ballast
Transporting ballast costs fuel.
The fact that every kilogram of extra weight increases your fuel consumption
means that it is worth taking a look in the luggage compartment to avoid trans-
porting any unnecessary ballast.
It i s par ti cula rl y in town traff ic, when one i s accel era ti ng qui te often, tha t the v ehicle
weight will have a significant effect upon the fuel consumption. A rule of thumb
here is that an increase in weight of 100 kilograms will cause an increase in fuel
consumption of about 1 litre/100 kilometres.
You may frequently also leave a roof rack fitted on just out of convenience,
although you no longer need it. The incr eased aerodynamic drag of your vehicle
causes it to use about 1 l more fuel than normal at a speed of 100 - 120 km/h, even
when you are not carrying a load on the roof.
Saving electricity
Gen era ti n g e l ect r icity costs fuel.
– Switch off electrical components as soon as you no longer need them.
When the engine is running, the alternator generates and supplies electrical power.
The greater the load on the alternator as a result of having a large number of elec-
trical components switched on, the more fuel will be consumed for operating the
alternator.

Unleaded petrol
A vehicle fitted with a petrol engine must always be refuelled with unleaded petrol
⇒ page 163. The automobile associations can provide you with information
regarding the locations of filling stations which offer unleaded petrol.
Headlight
The low beam of your headlights is set asymmetrically. It illuminates the side of the
road on which you are driving to a greater extent. If you drive abroad on the other
side of the road, you will dazzle oncoming traffic.
It is necessary in order to avoid dazzling oncoming traffic to stick a sticker over a
certain part of the headlights.
Headlight stickers can be obtained as a spare part from the Skoda Service Partners.
Headlights with Xenon lamps are designed for driving in countries with traffic on
the right or on the left. Have this do ne always at a Škoda Service Partner.
Note
You can obtain further information regardin g masking over or converting the head-
lights from your Škoda Service Partner.
Avoiding damage to your vehicle
When driving on poor roads and lanes or when driving over kerbstones, steep
ramps etc., you must pay particular attent ion to ensuring that any low-slung parts
of the vehicle, such as spoiler and ex haust, do not touch the ground and get
damaged.
This particularly applies to models with a lowered suspension (sport suspension)
and also when your vehicle is fully laden.

Towing a trailer
Towing a trailer
Technical requirements
The towing device must satisfy certain technical requirements.
Your vehicle is designed primarily for tran sporting persons and luggage. It can,
however, also be used for towing a trailer - provided certain technical equipment is
fitted.
If your vehicle has alre ady been supplied with a factory-fitted towing device then
everything that is necessary for towing a tr ailer in technical terms, and in terms of
the law, has already been taken into account.
Your vehicle is fitted with a 13-pin powe r socket for the electrical connection
between the vehicle and trailer. If the trailer which you wish to tow has a 7-pin
connector , you can use a suitable adapter
4) from Škoda original accessories.
This work must be carried out in accordan ce with the manufacturer's specifications
if a towing device is retrofitted.
Škoda Service Partners are familiar with details relating to retrofitting a towing
device and for any necessary modi fications to the cooling system.
WARNING
We recommend that you have the towing device from Škoda original acces-
sories installed by a Škoda Service Partner. H e is fa m il ia r wit h al l the re le v a nt
details relating to retrofitting such equipment. There is a risk of an accident
if the towing device is not properly fitted!
General Maintenance
There are a number of points to pay attention to when towing a
trailer.
Trailer load
The permissible trailer load must on no account be exceeded.
You can negotiate appropriately steeper incl ines and descents if you do not make
full use of the permissible trailer load.
The trailer loads specified only apply for altitudes up to 1 000 metres above mean
sea level. The fact that the engine power ou tput drops with increasing height due to
a lowering of air pressure and thus the abil ity to climb, means that the towed weight
must be reduced by 10% for every further increase of 1 000 metres in height above
sea level. The towed weight is the weight of the (laden) vehicle and the (laden)
trailer together. One should take this into account before driving up to higher alti-
tudes.
The trailer and drawbar load information on the type plate of the towing
device are merely test data for the towi ng device The data relating to your
vehicle, which is often less than this test data, can be found in your vehicle
registration documents.
Distribution of the load
Distribute the load in the trailer in such a way that any heavy items are located as
close as possible to the axle. Secure the items to prevent them slipping.
Tyre pressure
Select the tyre inflation pressure on yo ur vehicle for that of “fully laden”,
⇒ page 200. The inflation pressure of the tyres fitted to the trailer adjust in accord-
ance with the manufacturer's recommendation.
Exterior mirrors
You have to have additional exterior mirr ors fitted if you are not able to see the
traffic behind the trailer with the standard rear-view mirrors. Both exterior 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 headlights.
Alter the setting as necessary with the aid of the headlight beam adjuster
⇒ page 48.
Detachable ball head
The ball rod is detachable on vehicles wh ich 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 171.
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/h 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 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 engi ne speed when the outside temperature is
very high ⇒page 12.
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 190, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 26, “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

of the engine speed. One should also not
drop a gear for this reason when towing
a trailer as long as the engine can manage the slope without any drop in speed.
Detachable towing device*
The detachable ball head of the towing devi ce is stowed in the spare wheel well in
the luggage compartment.
An instruction for correct installation and removal of the ball head of the towing
device is supplied with the ball head
Inspect the ball head to ensure that it is pr operly locked each time before setting off.
The inspection is performed by turning th e closed locking lever downwards. If the
locking lever can only be turned around a small angle (approx. 5°), the locking
mechanism is O.K. After the inspection pull the locking lever back again to its stop.
The towing device must not be used, if it does not wish to close or the locking lever
turns slightly in the closed position.
WARNING
Do not use any aids or tools for installing or removing the ball head. This
might result in damage to the lockin g mechanism to the extent that the
safety of the towing device is no longer assured - risk of an accident.
Note
•Do not carry out any modifications or repairs to the ball head or to any other
components on the towing device.
•Contact a specialist garage if you en counter any problems using the device.
•Never unlock the ball head with a trailer coupled to it.
•You should take off the ball head if yo u drive without towing a trailer. Inspect
whether the end cover properly seals off the mounting shaft.
•Remove the ball head beforehand if yo u wish to clean your vehicle using a
steam jet. Ensure that the end cover properly seals the mounting shaft.
•It is recommended to wear gloves when installing and removing.

Taking care of your vehicle and cleaning the vehicle177
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Wheels
Steel wheels
You should also thoroughly wash the wheels and wheel trims when giving your
vehicle its regular wash. This prevents any brake dust, dirt and road salt from
sticking to the wheel hubs. You can remove stubborn brake abrasion adhering to
t h e w h e e l s w i t h a n i n d u s tr i a l c l e a n e r. To u c h u p a n y d a m a g e to t h e p a i n tw o r k o n th e
wheels before rust is able to form.
Light alloy wheels
Regular care of light alloy wheels is necessary in order to retain their decorative
appearance over long periods. It is partic ularly important to remove any road salt
and brake abrasion from light alloy wheels every two weeks, otherwise the surface
will suffer. Wash thoroughly and then treat the wheels with a protective product for
light alloy wheels which does not contain any acidic components. You should
provide the wheel hubs with a hard wax la yer every three months. You must not use
any products which cause abrasion when treating the wheel hubs. Any damage to
the paint layer on the wheel hubs must be touched up immediately.
We recommend using a preservative from Škoda genuine accessories offered by
your Škoda dealer.
WARNING
One should remember when cleaning th e wheels that moisture, ice and road
salt may adversely affect braking ef ficiency - risk of an accident!
Note
Severe layers of dirt on the wheels can also result in wheel imbalance. This may
show itself in the form of wheel vibration which is transmitted to the steering wheel
which, in certain circumstances, can caus e premature wear of the steering. It is
therefore important to clean dirty wheels.
Underbody protection
The underside of your vehicl e is protected for life against chemical and mechanical
influences.
One cannot, however, completely rule out damage to the protective layer when
driving so we recommend that you inspect the protective layer on the underside of
your vehicle and on the chassis at certain in tervals - this is best done at the begin-
ning and end of the winter - and to touch up any damaged areas.
Škoda Service Partners have suitable spray products available as well as the neces-
sary equipment and are familiar with the instructions for use. It is therefore best to
have such touch-up work or additional corrosion protection measures carried out
by a Škoda Service Partner.
WARNING
Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converte rs, diesel particle filter or heat
shields. When the engine reaches its operating temperature, these
substances might ignite - risk of fire!
Protection of hollow spaces
All the cavities of your vehicle which are at risk from corrosion are protected for life
by a layer of protective wax applied in the factory.
This wax protection does not require to be inspected or re-treated. Please remove
any small amount of wax which flows out of the cavities at high temperatures with
a plastic scraper and clean the spot using petroleum cleaner.
WARNING
Safety and environmental protection regulations should observed when
using petroleum cleaner to re move wax - a risk of fire!
