cates that your vehicle is equipped with
a diesel particle filter. The vehicle
data sticker is located on the floor of the luggage compartment and is also stated in the Service schedule.The diesel particle filter filters the soot particles completely from the exhaust. The soot is collected in the diesel particle filter and burnt regularly. To assist this proce- dure, we recommend not to drive
regularly over short distances.
If the diesel particle filter is clogged or there is a fault, it is indicated by the warning light

.WARNING
•
The diesel particle filter
achieves very high te
mperatures. 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 garage wi
ll be able to tell you which countries use
only diesel fuel with high sulphur content.

Driving and the EnvironmentA new engineThe engine has to be run in during 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 engaged, 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 harmonized. The driving style which you adopt during the first approx.1 500 kilometres
plays a decisive 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
complete. The maximum permissib
le engine spee
d 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 figure
s 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 tyresNew 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 padsAllow for the fact that new brake pads do
not achieve their full braking efficiency
until approximately 200 kilometres. New brake 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 converterProper operation of the emission co
ntrol system (catal
ytic 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 219, “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 225, “Replenishing
engine oil”.
– Do not tow-start the vehicle over a
distance of more than 50 metres
⇒
page 252, “Tow-starting and towing vehicle”.
If you drive your vehi
cle 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 which 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, catalyti
c converters or heat shields. Such
substances might ignite when driving - risk of fire!
Caution
•
Vehicles fitted with
catalytic converter should neve
r 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 le
aded petrol will resu
lt in the catalytic
converter being destroyed.•
If you detect a power reduction or ir
regular engine runni
ng 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 ex
haust system and da
mage 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 en
gine. This depends on the
sulphur content of the fuel. It is often su
fficient to refuel with unleaded premium-
grade petrol of a different brand or at a different filling station.Driving in an economical and environmentally conscious mannerGeneral 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.

The fuel consumption can naturally also be
influenced by factors which are beyond
the driver's control. It is,
for example, normal for the fu
el consumption to increase
in winter and under worsened
conditions such as poor road conditions, towing a
trailer, etc. The technical requirements for low fuel
usage and economic efficiency of the
vehicle have already been built into the ve
hicle at the works.
Special attention has
been given to minimising ne
gative effects on the environment. It is necessary to
take note of the guidelines given in this
chapter in order to make best use of these
characteristics and to maintain their effectiveness. The optimal engine speed should be obtained when accelerating, in order to avoid a high fuel consumption an
d resonance of the vehicle.
Looking ahead when driving A vehicle's highest fuel consumption occurs it accelerates.Avoid accelerating and brakin
g unnecessarily. If you drive
with forsight you will not
need to brake so often and will also then
not have to accelerate so much. Let your
vehicle coast to a stop, for example, if this
is possible, when you see that the next
set of traffic lights is at red.Shifting gears and saving energy Shifting up early saves on fuel.
Manual gearbox – Drive no more than about one length of your vehicle in first gear. – Always shift up into the next higher gear at approx. 2 000 to 2 500 revs. Automatic gearbox – Depress the accelerator pedal
slowly
. Do not depress it beyond the
kickdown position, however.
An effective way of achieving good
fuel economy is to shift up
early
. You will
consume more fuel if you drive at unnecessa
rily high revolutions in any given gear.
The
⇒fig. 194
shows the ratio of fuel consumption to the speed of your vehicle in
the relevant gears. Fuel consumption in 1st
gear is the highest, while that in 5th or
the 6th gear is the lowest. Only depress the accelerator pedal slowly if
your vehicle is fitted with an automatic
gearbox in order to automatically select an economic driving programme. You will achieve good fuel economy by shifting
up early and shifting down late.
Note
Also use the information supplied by the multi-functional indicator*

Avoiding full throttle Driving more slowly means saving fuel.Sensitive use of the accelera
tor will not only significantly reduce fuel consumption
but also positively influence environmen
tal pollution and wear of your vehicle.
You should avoid fully exploi
ting the top speed of your vehicle wherever possible.
Fuel consumption, pollutant emissions and vehicle noises increase disproportion- ally at high speeds. The
⇒fig. 195
shows the ratio of fuel consumption 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 moto
ring even before you set off on your
journey. Keeping your vehicle properly servic
ed 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 consum
ption 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.

Technical Data
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. 15 - 20 litres/100 km of fuel immediately after starting. Fuel co
nsumption drops to 10 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. 196
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 is particularly in town traffic, when one
is accelerating quite often, that the vehicle
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 10% more fuel th
an normal at a speed of 100 - 120 km/h,
even when you are not carr
ying a load on the roof.
Saving electricity Generating electricity 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.

Keeping a log of your fuel consumptionIf you really wish to ke
ep a close check on your
fuel consumption
, it is best to enter
the figures in a logbook. This does not take
much time but is a very worthwhile exer-
cise. It enables you to detect any change
(positive and negative) at an early stage
and to take any appropriate action. If you find that your fuel
consumption is too high, you sh
ould reflect on how, where
and in what conditions you have driven
the vehicle since you last refuelled.
Environmental compatibilityEnvironmental protection has played a majo
r role in the design, selection of mate-
rials and manufacture of your new Škoda.
Particular emphasis
has been paid to a
number of aspects, including: Design measures•
joints designed to be easily detached,
•
simplified disassembly due to the modular structure system,
•
improved purity of different classes of materials,
•
Identification of all plastic parts in
accordance with VDA Recommendation 260,
•
Reduced fuel consumption
and exhaust emission CO

•
Minimum fuel leakage during accidents,
•
Reduced noise.
Choice of materials•
extensive use of recyclable material,
•
Air conditioning filled wi
th CFC-free refrigerant,
•
no cadmium,
•
no asbestos,
•
Reduction in the “vaporisation” of plastics.

solvent-free protection of the vehicle for transportation from the production
plant to the customer,•
The use of solvent-free adhesives,
•
No CFCs used in the production process,
•

•
Use of water-soluble paints.
Motoring abroadGeneral Other circumstances may exist abroad.It is also possible, in certain countries, that the Škoda Service Partner network is limited or has not been established yet.
This is the reason why obtaining certain
spare parts may be somewhat complicate

about technical aspects of the vehicle,
required maintenance work and possibilities for getting repairs done.Unleaded petrolA vehicle fitted with a petrol engine must always be refuelled with unleaded petrol ⇒ page 202. The automobile associations can provide you with information regarding the locations of filling stations which offer unleaded petrol.HeadlightThe low beam of your headlights is set asym
metrically. 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 wi
ll dazzle oncoming traffic.
In order to prevent the dazzling of oncoming
traffic, it is necessary that an adjust-
ment of the headlights is carried out by
your authorised Škoda Service Partner.

Towing a trailer
208
Towing a trailerTo w i n g a t r a i l e rTechnical requirements The towing device must satisfy
certain technical requirements.
Your vehicle is designed primarily for tr
ansporting persons and luggage. It can,
however, also be used for towing a traile
r - provided certain te
chnical equipment is
fitted. If your vehicle has already been supplied with a
factory-fitted
towing device then
everything that is necessary
for towing a trailer in technical terms, and in terms of
the law, has already been taken into account. Your vehicle is fitted with a 13-pin po
wer socket for the electrical connection
between the vehicle and trailer. If th
e trailer which you wish to tow has a
7-pin
connector
, you can use a suitable adapter
15) from Škoda original accessories.
This work must be carried out in accordan
ce with the manufacturer's specifications
if a towing device is retrofitted. Authorised Škoda Service Partners are familiar with details relating to retrofitting a towing device and for any necessary
modifications to the cooling system.
WARNING
We recommend that you have the towing device from Škoda original acces- sories installed by an authorised Škoda Service Partner. He is familiar with all the relevant 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 appropriatel
y steeper inclines and desc
ents if you do not make
full use of the perm
issible 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 tow
ing 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 inflation pressure Select the tyre inflation pressure on your vehicle for that of “fully laden”, ⇒ page 235. 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 mirrors fitted if you are not able to see the
traffic behind the trailer with the standard rear-view mirrors. Both exterior mirrors

supplied with the towing device.

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 th
e aid of the headlight beam adjuster
⇒ page 66, “Headlamp range adjustment*
”.
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 210.
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/hour for safety reasons. This also applies for coun- tries 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, particul
arly 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 engine speed when the outside temperature is very high
⇒page 18, “Coolant temperature gauge”.
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 227, “Inspecting the coolant level”. Please refer to the following guidelines
⇒page 38, “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 en
gine can manage the slope
without any drop in speed.
Detachable towing device*The detachable ball head of the towing device
is stowed in a box for the car tool kit
in the spare wheel well in the luggage compartment. An instruction for correct installation an
d 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 the 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 locking 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 you 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.
