Note
If the battery has been disconnected
and reconnected, the warning light
 comes
on after switching on the ignition. The warn
ing light must go out after driving a short
distance.Electronic stability programme (ESP)*

The warning light
 comes on for a few seconds when the ignition is switched on.
Components of the ESP system also include the Traction Control System (TCS), Electronic Differential Lock (EDL), an
d the Antilock Brake System ABS (ABS).
The warning light comes on when drivin
g when a control cycle is activated.
The warning light will come on and remains on if the ESP is switched off or if there is a fault in the system. The fact that the ESP system operates together with the ABS means that the ESP warning light will also come on if the
ABS system is not operating properly.
If the warning light
 comes on immediately after starting the engine, the ESP
system can be switched off for technical
reasons. In this case, the ESP system can
be switched on again by switching the ignition on and off. If the warning light goes out, the ESP system is fully functional again. Further information on the ESP
⇒page 193, “Electronic stability programme
(ESP)*”. Electronic Differential Lock (EDL)* The EDL is a part of the ESP. A fault in the EDL is indicated by the ESP warning light in the instrument cluster. Have the vehicle inspected without delay by an author- ised Škoda Service Partner. Further information on the EDL
⇒page 194, “Electronic
Differential Lock (EDL)*”.

Adopt the correct seated position
⇒page 164, “Correct seated position”. Also
inform your occupants to adop
t the correct seated position.
•
Fasten the seat belt correctly. Also inform your occupants to properly fasten the
seat belts
⇒page 170, “How are seat belts correctly fastened?”.
What influences the driving safety? The driving safety is primarily dete
rmined by the style of driving and
the personal behaviour of all the occupants.The driver is fully responsible for himself and his occupants. If your driving safety is effected, you place yourself and the oncomi
ng traffic at risk. Please refer to the
following guidelines.•
Do not get distracted from concentrating on the traffic situation, e.g. by your
occupants or mobile phone calls.
•
Never drive when your driving ability is impaired, e.g. through medication,
alcohol, drugs.•
Keep to the traffic regulations and the permissible speed limit.
•
Adjust the driving speed at all times to the road condition as well as to the traffic
and weather conditions.•
Take regular breaks on long journeys - at the latest every two hours.
Correct seated positionCorrect seated position for the driver Correct seated position for the dr
iver is important for safe and
relaxed driving.

Tyre inflation pressu
re-control system*
The tyre inflation pressure-control system compares with the aid of the ABS sensors the speed and also the rolling circumference
of the individual wheels. If the rolling
circumference of a wheel is changed, the warning light°
 lights up in the instru-
ment cluster
⇒page 39. The rolling circumference of the tyre can change if:
•
the tyre inflation pressure is too low,
•
the structure of the tyre is damaged,
•
the vehicle is loaded on one side,
•
the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill),•
snow chains are mounted,
•
the temporary spare wheel is mounted,
•
one wheel per axle was changed.
Basic setting of tyre inflation pressure-control system After changing the tyre inflation pressures or after changing one or several wheels, a basic setting of the system must be carried out as follows.•
Inflate all tyres to the specified inflation pressure
⇒page 235.
•
Switch on the ignition.
•
Press button

for more than 2 seconds. While pressing the
button, the warning light
 lights up. At the same time the memory of the system
is erased and the new calibration is star
ted, which is confirmed with an audible
signal and then the warning light
 goes out.
•
If the warning light
 does not go out after the basic setting, there is a fault in
the system. Have the vehicle inspected by your nearest specialist garage. Warning light
 lights up
If the tyre inflation pressure of at least on
e wheel is insufficiently inflated in compar-
ison to the stored basic value, the warning light
 ⇒
lights up.
Warning light
 flashes
If the warning light flashes, there is a system fault. Have the vehicle inspected by your nearest specialist garage.
WARNING
•
When the warning light
 lights up, immediately reduce the speed and
avoid sudden steering and brake mano
euvres. Please stop the vehicle
without delay at the nearest possible stop and inspect the tyres and their inflation pressures.•
The driver is responsible for the correc
t tyre inflation pressures. For this
reason, the tyre inflation pressures must be checked regularly.•
Under certain circumstances (e.g. sporty style of driving, wintry or
unpaved roads) the warning light
 can be delayed or does not light up at
all.•
The tyre inflation pressure-control system does not take away the
responsability from the driver for the correct tyre inflation pressure.
Note
The tyre inflation pressure-control system:•
does not replace the regular tyre inflatio
n pressure control, because the system
cannot detect an even pressure loss,•
cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of
sudden tyre damage. In this
case carefully bring the vehi
cle to a standstill without
sudden steering movements and without sharp braking.

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.

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
15)In some countries the adapter is
supplied with the towing device.

Wheels and TyresWheelsGeneral information•
New tyres do not offer optimal grip at first and should therefore be run in for
about 500 km at a moderate speed and an
appropriately cautious style of driving.
You will also profit from longer tyre life.•
The tread depth of new tyres may differ
because of design features and the
configuration of the tread (depending on
the type of tyre and the manufacturer).
•
Drive over curbs on the side of the road
and other such obstacles slowly and,
where possible, at a right angle in order to avoid damage to tyres and wheel trims.•
Inspect your tyres from time to time
for damage (punctures, cuts, splits and
bulges). Remove foreign bodies from the tyre profile.•
Damage to tyres and wheels is frequent
ly not visible. Unus
ual vibrations or
pulling of the vehicle to one side
could be a sign of tyre damage.
Please reduce
your speed immediately and stop if
you suspect that a wheel is damaged.

Inspect the tyres for signs of damage (bulges,
splits, etc.). If no
visible damage is
present, please drive at an appropriatel
y slow speed and carefully to the nearest
specialist garage in order to have your vehicle inspected.•
Also protect your tyres from contact with oil, grease and fuel.
•
Immediately replace any dust caps of the valves which have got lost.
•
Mark wheels before removing them so th
at their previous direction of running
can be maintained when mounted them again.•
Always store wheels or tyres which been removed in a cool, dry and, where
possible, dark place. Tyres which are not fixed to a wheel trim should be stored upright. Unidirectional tyres* The direction of rotation of the tyres is marked by arrows on the wall of the tyre. This indicates the direction of rotation of the tyre, and it is essential that the tyres are fitted on to run in this direction. Only then
are the tyres able to provide the optimal
properties in terms of grip, low noise, wear-and-tear and aquaplaning.
Further information concerning
the use of unidi
rectional tyres
⇒page 239.
WARNING
•
New tyres during the first 500 km do not offer optimal grip and should
therefore be run appropriately - risk of accident!•
Never drive with damaged tyres - risk of accident!Note
Please observe the various differing legal requirements regarding tyres.Tyre lifeThe life of your tyres very much depends on the following points: Tyre pressure The working life of tyres will be shortened considerably if the tyres are insufficiently or over-inflated and this will have an advers
e effect on the handli
ng of your vehicle.
Correctly inflated tyres are of partic
ular importance when travelling at
high speeds
.
It is therefore good to check the pressure at least once a month and also before

setting off on a long trip. Please do not forget the spare wheel when checking the tyres. The tyre inflation pressures for
summer tyres
are indicated on the inside of the fuel
filler flap
⇒page 235, fig. 210
. The inflation pressures for
winter tyres
are 20 kPa
(0.2 bar) higher than those for summer tyres
⇒page 239.
The tyre pressure should be at the highest pressure specified for your vehicle at all times. The tyre inflation pressure of the emergency spare wheel R 18 is 420 kPa (4.2 bar).Always check the inflation pressure of ty
res when cold. Do not reduce the higher
pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if your vehicle is carrying a significantly higher payload. Driving style Fast cornering, sharp acceleration and braking (squealing tyres) increase wear-and- tear on your tyres. Balancing wheels The wheels of a new vehicle are balanced. There are a wide range of influences when driving which may result in an imbalance and which makes themselves felt through vibration in the steering. You should have the wheels rebalanced
since any imbalance increases wear-and-
tear on the steering, the suspension and
tyres. A wheel must also be rebalanced
when a new tyre is fitted and each time a tyre is repaired. Wheel alignment errors Incorrect wheel alignment at the front and re
ar will not only increase wear-and-tear
on the tyres but will also has an adverse
effect on vehicle safety. Contact your
specialist garage if you notice any unusual tyre wear.
WARNING
•
If the inflation pressure is too low,
the tyre must perform a greater flexing
work. At higher speeds the tyre will warm up as a result of this. This can result in tread separation and even a tyre blowout.•
Immediately replace the damaged rims or tyres.
For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption.Wear indicatorsThe base of the tread of the original tyres has wear indicators 1.6 mm high, installed at right angles to the direction of travel. These wear indicators are located at 6 - 8 points depending on the make and are evenly spaced around the circumference of the tyre
⇒fig. 211
. Markings on the walls of the
tyres through the letters “TWI”,
triangular symbols or other symbols identi
fy the position of the wear indicators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the wear indicators, means that your tyres
have reached their legally permissible
minimum tread depth.
WARNING
•
You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn do
wn. The legally permissible minimum
tread depth should be observed.•
Worn tyres do not provide the necessar
y adhesion to the road surface at
high speeds on wet roads. One coul
d experience “aquaplaning” (uncon-
trolled movements of the vehicle - “swimming” on a wet road surface).

Spare wheel*The spare wheel lies in a well under the floor covering of the luggage compartment and is fixed in place using special screws
⇒fig. 216
.
Before removing the spare wheel, you must take out the box with the vehicle tool kit box
⇒page 244, fig. 215
.
One should check the inflation pressure in the spare wheel (at best when generally checking the tyre air pressures - see sign on the fuel filler flap
⇒page 235) to
ensure that the spare wheel is always ready to use. Temporary spare wheel A warning label displayed on the rim of the temporary spare wheel indicates that your vehicle is equipped with a temporary spare wheel. Please observe the following notes when driving with a temporary spare wheel:•
After fitting on the wheel, the warning stic
ker must not be concealed (e.g. by the
wheel trim).•
Do not drive with this spare wheel at more than 80 km/h - risk of accident. Avoid
accelerating at full throttle, sharp braking and fast cornering.•
The inflation pressure for this spare wheel is identical to the inflation pressure
of the standard tyres. The temporary spare wheel R 18 must have an inflation pres-sure of 420 kPa (4.2 bar)!
•
Use this spare wheel only to reach the nearest specialist garage as it is not
intended for continuous use.•
No other summer or winter tyres must
be mounted on the rim of the spare
wheel R 18.Changing a wheelPreliminary workThe following steps should be carried out before actually changing the wheel. – If it is necessary to change a wheel, park the vehicle as far away as
possible from the traffic flow. The place you choose should be
level
.
–Have
all the occupants get out.
While changing a wheel, the occu-
pants of the vehicle should not stan
d on the road (e.g. behind a crash
barrier).
– Apply the
handbrake
firmly.
–Engage
1st gear
or if your vehicle is fitted with an automatic gearbox,
position the
selector lever into position P

•
If you find yourself in flowing traffic switch on the hazard warning lights
system and place the warning triangle
on the side of the road at the
prescribed distance from
your vehicle while obse
rving all national legal
provisions. In this way you are protecting not only yourself but also other road users.
