order to be able to move the selector lever out of the position P or N.
Further information about the selector lever lock page 116.
Tyre inflation pressure*

The warning light
 lights up, if there is a substantia l drop in inflation pressure in one
of the tyres. Reduce the speed and check or correct as soon as possible the inflation
pressure in the tyres page 208.
If the warning light flashes, there is a system fault. Visit the nearest specialist garage and
have the fault rectified.
Further information about the tyre pressure monitoring system page 172.
WARNING

When the warning light
 lights up, immediately reduce the speed and
avoid sudden steering and brake manoeuvr es. Please stop the vehicle without
delay at the nearest possible stop and in spect the tyres and their inflation pres-
sures.

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.
Note
If the battery has been disconnected, the warning light
 comes on after switching on
the ignition. The warning light must go out after driving a short distance.
Antilock brake system (ABS)

The warning light
 shows the functionality of the ABS.
The warning light comes on for a few seconds after the ignition has been switched on
or when starting the engine. The warning light goes out after an automatic check
sequence has been completed. A fault in the ABS
The system is not functioning properly if the ABS warning light
 does not go out
within a few seconds after switching on the igni tion, does not light up at all or lights up
while driving. The vehicle will only be br aked by the normal brake system. Visit a
specialist garage immediately and adjust your style of driving appropriately as you will
not know how great the damage is.
Further information about ABS page 171, “Antilock brake system (ABS)”.
A fault in the entire brake system
If the ABS warning light
 comes on together with the brake system warning light

(handbrake must be released), there is a fault not only in the ABS but also in another
part of the brake system .
WARNING

If the brake system warning light
 comes on together with the ABS
warning light
 stop the vehicle immediately an d check the brake fluid level in
the reservoir page 202, “Brake fluid”. If the fluid level has dropped below the
MIN marking, do not drive any further - risk of accident! Obtain professional
assistance.

Pay attention to the following instructions before checking the brake fluid
level and opening the bonnet page 197, “Working in the engine compart-
ment”.

If the brake fluid is at the correct leve l, the ABS control function has failed.

Intelligent Technology
172
The Brake Assist is able to help you achieve a shorter braking distance in emergency
situations by rapidly producing the pressure required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function of the
Brake Assist is automatically switched off and the brakes operate in the normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist
function is also not available. Further information on the ESP page 167.
WARNING

The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the braking distance required.

Adapt your speed to the conditions of the road surface and to the traffic situ-
ation.

The increased safety offered by the Brake Assist must not tempt you to take
a greater safety risk than otherwise.
Uphill Start Assist*The uphill start assist makes it easier to start off on steep hills. The system assists a start
off by holding the brake pressure produced by the brake pedal actuation for approx. 2
seconds after releasing the brake pedal. The driver can therefore move his foot from
the brake pedal to the accelerator pedal and start off on the slope, without having to
actuate the handbrake. The brake pressure drops gradually the more you operate the
accelerator pedal. If the vehicle does not start off within 2 seconds, it starts to roll back.
The uphill start assist is active as of a 5 % slope, if the driver door is closed. It is always
active on slopes when in forward or reverse start off. When driving downhill, it is
inactive.Electromechanical power steeringThe power steering enables you to steer the vehicle with le ss physical force.
With the electromechanical power steering , the steering assist is automatically
adapted to the speed and to the steering angle. It is still possible to fully steer the vehicle if the power steering fails or if the engine is
not running (vehicle being towed in). The only difference is that greater physical effort
is required.
If there is a fault in the power steering, the warning light
 or  lights up in the instru-
ment cluster page 30.
WARNING
Contact your specialist garage if the power steering is defective.Tyre pressure monitoring system*The tyre pressure monitoring system compares with the aid of the ABS sensors the
speed and also the rolling circumference of the individual wheels. If the rolling circum-
ference of a wheel is changed, the warning light
 lights up in the instrument cluster
 page 33 and an audible signal sounds. 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,

Basic setting of the system
After changing the tyre inflation pressures, after changing one or several wheels, the
position of a wheel on the vehicle (e.g. exch anging the wheels between the axles) or
when the warning light lights up while drivin g, a basic setting of the system must be
carried out as follows.

Inflate all tyres to the specified inflation pressure page 208.

Switch on the ignition.

Press button  page 172, fig. 151 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 started, 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 one wheel is insufficiently inflated in comparison
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 manoeuvr es. Please stop the vehicle without
delay at the nearest possible stop and in spect the tyres and their inflation pres-
sures.

The driver is responsible for the correct tyre inflation pressures. For this
reason, the tyre inflation pressu res 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 pressure monitoring system does not take away the responsibility
from the driver for the correct tyre inflation pressure.
Note
The tyre pressure monitoring 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 ca refully bring the vehicle to a standstill without sudden
steering movements and without sharp braking.

In order to ensure a proper functioning of the tyre inflation pressure-control
system, it is necessary to carry out the ba sic setting again every 10 000 km or 1x a
year.
Diesel particle filter* (diesel engine)In the diesel particle filter the resu lting soot particles are collected and
burnt during the combustion of diesel fuel.Code 7GG, 7MB or 7MG on the vehicle data sticker, see fig. 152 , indicates that your
vehicle is equipped with a diesel particle fi lter. 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 procedure, we
recommend not to drive regu larly over short distances.

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 we ar and the driving behaviour will worsen.
Always check the inflation pr essure 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 transporting 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 consump-
tion 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 increased aerodyna mic drag of your vehicle causes it to use
about 10% 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
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 electrical
components switched on, the more fuel will be consumed for operating the
alternator.
Keeping a log of your fuel consumptionIf you really wish to keep 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 (p ositive and negative) at an early stage and
to take any appropriate action.
If you find that your fuel consumption is too high, you should reflect on how, where
and in what conditions you have driven the vehicle since you last refuelled.Environmental compatibilityEnvironmental protection has played a major role in the design, selection of materials
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 differ ent 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 re cyclable material.

Air conditioning filled with CFC-free refrigerant.

No cadmium.

No asbestos.

Reduction in the “vaporisation” of plastics.

Towing a trailer
182
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 technical equipment is
fitted.
If your vehicle has already been supplied with a factory-fitted towing device then
everything that is nece ssary 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 power socket for the electrical connection between
the vehicle and trailer. If the tr ailer which you wish to tow has a 7-pin connector, you
can use a suitable adapter
16) from Škoda original accessories.
This work must be carried out in accordance 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 accesso-
ries 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 appropriately steeper inclin es 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 engi ne power output 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 altitudes.
The trailer and drawbar load information on the type plate of the towing device
are merely test data for the towing device The data relating to your vehicle, which
is often less than this test data, can be found in your vehicle registration docu-
ments.
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 th e items to prevent them slipping.
Tyre inflation pressure
Select the tyre inflation pressure on yo ur vehicle for that of “fully laden”, page 208.
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 ex terior mirrors 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.
16)In some countries the adapter is supplied with the towing device.s43s.1.book Page 182 Thursday, May 13, 2010 1:21 PM

RefuellingFig. 159 Right rear side of the vehicle: Open fuel filler flap / fuel filler flap with cap unscrewedThe filler flap is automatically unlocked or locked* with the central locking.Opening the fuel filler cap– Press in the middle of the left area of the fuel filler flap in direction of arrow
 fig. 159 .
– The fuel filler cap on the fuel filler tube must be unlocked to the left using the
vehicle key (only valid for vehicles which do not have automatic unlocking of the
fuel filler flap).
– Unscrew the fuel filler cap anti-clockwise and place the fuel filler cap from above
on the fuel filler flap fig. 159 - right.Closing fuel filler cap– Screw on the fuel filler cap by turning it to the right until it is heard to click.
– The fuel filler cap on the fuel filler tube mu st be locked to the right using the vehicle
key (only valid for vehicles which do not ha ve automatic locking of the fuel filler
flap).
– Close the fuel filler flap until it locks.
The correct grade of fuel for your vehicle as well as the tyre size and inflation pressures
are stated on a sticker affixed to the inside of the fuel filler flap. Further information on
fuel page 192. The fuel tank has a capacity of about 55°litres or 60 litres
17).
WARNING
Pay attention to any legal requirements if
you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for
safety reasons. The canister can be damaged in the event of an accident and fuel
may leak out.
Caution

Before refuelling it is necessary to switch off the auxiliary heating system (auxiliary
heating and ventilation) *.

Remove any fuel which has spilled onto th e paintwork of your vehicle immediately
- risk of paint damage!

On vehicles fitted with a ca talytic converter, never let the fuel tank run completely
empty. An irregular supply of fuel to the engine can result in misfiring and unburnt fuel
may get into the exhaust system, which may result in overheating and damage to the
catalytic converter.

Make sure that the valve is not pressed into the filler tube when inserting the pump
nozzle into the filler tube. Otherwise you ar e unintentionally filling up the volume,
which in case of heat can cause an expansion of the fuel. This can lead to an overflow
of fuel or damage to parts of the fuel reservoir.

The fuel tank is full just as soon as the pump nozzle switches off for the first time,
provided the nozzle has been operated properly. Do not continue refuelling - other-
wise the expansion volume is filled up.

Wheels and Tyres
208
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 appropri ately cautious style of driving. You will
also profit from longer tyre life.

The tread depth of new tyres may differ be cause of design features and the config-
uration 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 frequently not visible. Unusual vibrations or pulling
of the vehicle to one side coul d be a sign of tyre damage. Please reduce your speed
immediately and stop if you su spect 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
appropriately 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 that 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 mark ed 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 proper-
ties in terms of grip, low nois e, wear-and-tear and aquaplaning.
Further information concerning th e use of unidirectional tyres page 212.

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.Ty re l i feThe 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 adverse effect on the handling of your vehicle.
Correctly inflated tyres are of particular 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 fig. 169 . The inflation pressures for winter tyres are 20 kPa (0.2 bar) higher
than those for summer tyres page 212.

Technical Data
The tyre inflation pressure for tyres of the tyre size 205/50 R17, which are intended to
be used with snow chains, is identical to the tyre inflation pressure for tyres of the tyre
size 225/45 R17, see
page 208, fig. 169 .
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 tyres when cold. Do not reduce the higher pres-
sure 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 brak ing (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 si nce 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.

Tyres which are 6 years old or more should only be fitted in exceptional
cases and when adopting an approp riately cautious style of driving.
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. 170 . Markings on the walls of the tyres through the letters “TWI”, triangular
symbols or other symbols identify th e 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 down . The legally permissible minimum tread
depth should be observed.

Worn tyres do not provide the necessary adhesion to the road surface at
high speeds on wet roads. One could experience “aquaplaning” (uncontrolled
movements of the vehicle - “swimming” on a wet road surface).
