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 vehicle
174
Automatic vehicle wash systems
The paintwork of the vehicle is sufficiently resistant that the vehicle can be washed
normally in automatic vehicle wash plants without any problem. The actual stress
to which the paintwork is subjected, however, depends greatly on the design of the
vehicle wash system, the filtering of the water and the type of washing and care
products used. If the paintwork of your vehicle appears mat after being washed or
even has scratches, point this out to the operator of the vehicle wash plant. Use a
different vehicle wash plant, if necessary.
There are no particular points to note be fore washing your vehicle in such a plant
other than the usual precautionary measur es (closing windows and sliding/tilting
roof, moving any factory-fitted aerials down flat against the bodywork, etc.).
If you have any particular atta ch e d p a r t s f i t te d t o y o u r c a r - s u ch a s s p o i l e r, ro o f ra ck
system, two-way radio aerial - it is best to first of all consult the operator of the car
wash plant.
It is important to degrease the lips of the windscreen wiper rubbers after passing
through the automatic vehicle wash system.
Caution
Do not screw the swivelling down roof aeri al tight before washing the vehicle in an
automatic vehicle wash sy stem - risk of damage!
Washing vehicle by hand
It is important to first soften the dirt with plenty of water and rinse it off as thor-
oughly as possible before wa shing your vehicle by hand.
One should then clean the vehicle using a soft washing sponge, washing glove or
a washing brush and only slight pressure. Work from the top to the bottom -
beginning with the roof. Only place slight pressure on the vehicle paintwork during
cleaning Only use a car shampoo for stubborn dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for such areas. Rinse off the vehicle well after giving it a wash and dry it off using a chamois leather.
WARNING
•The ignition should always be switched off when you wash your vehicle -
risk of accident!
•Protect your hands and arms from sharp-edged metal parts when you
are cleaning the underfloor, the inside of the wheel housings or the wheel
trims - risk of cuts.
Caution
•Do not wash your vehicle in bright sunlight - risk of paint damage.
•Ensure that the jet of water is not aimed directly at the locks or at the door and
panel joints if you spray your vehicle in winter down with a hose - risk of freezing.
•Do not use any insect sponges, rough ki tchen sponges or similar cleaning prod-
ucts - risk of damage to the surface of paintwork.
For the sake of the environment
Only wash your vehicle at washing bays specifically reserved for this purpose. This
ensures that no water which may be cont aminated by oil flows into the sewage
system. It is not even permitted to wash your vehicle in certain areas except at such
specific washing bays.
Washing with a high-pressure cleaner
When you wash your vehicle with a high-pressure cleaner, it is essential to comply
with the instructions for use of the cleaning equipment. This applies in particular to
the pressure used and to the spraying distance . Maintain a sufficiently large
distance to soft materials such as rubber hoses or insulation material.
On no account use circular spray nozzles or so-called dirt cutters!

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

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!

General comments
•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 angles 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. Unusual 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 (bulge s, 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 unidirectional tyres ⇒page 204.
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.

Ty re l i fe
The 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 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. 183 . The inflation pressures for winter tyres are 20 kPa (0.2 bar)
higher than those for summer tyres ⇒page 203.
The tyre pressure should be at the highest pressure specified for your vehicle at all
times.
On cars with full wheel trim, valve extensions are fitted in place of dust caps
⇒ fig. 184 . It is not nece ssary to unscrew the valve extensions in order to check and
alter the inflation pressure of the tyre.
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 signi ficantly 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 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 rear 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 no tice 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.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption.
Wear indicators
The 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. 185 . Markings on the walls of the tyres through the letters “TWI”,
triangular symbols or other symbols identify 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 necessary adhesion to the road surface at
high speeds on wet roads. One could experience “aquaplaning” (uncon-
trolled movements of the vehicle - “swimming” on a wet road surface).
Changing wheels around
If significantly greater wear is present on the front tyres, we recommend changing
the front wheels around with the rear wheels as shown in the diagram ⇒fig. 186 .
You will then obtain approximately the same life for all the tyres.
It may be advantageous to swap the tyre s over “crosswise” when certain types of
wear characteristic arise on the running surface of the tyres (but not in the case of
unidirectional tyres). Škoda Service Pa rtners can provide you with details.
We recommend that you change the wheels around every 10 000 km in order to
achieve even wear on all wheels and to obtain optimal tyre life.
New tyres and wheels
Tyres and wheel rims are important design elements. One should therefore use the
tyres and wheel rims which have been released for use by Škoda Auto. They are
exactly matched to the vehicl e type and therefore contribu te significantly to good
road holding and safe driving characteristics ⇒ .
Only fit radial tyres of the same type on all 4 wheels, size (rolling circumference)
and, if possible, the same tread pattern on one axle.
The Škoda Service Partners have access to the most current information about
which tyres we have released for use on your vehicle.

We recommend that you have any work rela ting to tyres or wheels carried out by
your Škoda Service Partner . Your dealer has all of the necessary special tools and
replacement parts available plus the required specialist knowledge and is also in a
position to properly dispose of the old tyres. A large number of Škoda Service Part-
ners also have an attractive range of tyres and wheels available.
The tyre/wheel combinations which are appr oved for your vehicle are indicated in
your vehicle documents. Approval and lice nsing may differ according to the legis-
lation prevailing in individual countries.
Proper knowledge of the tyre data makes it easier for you to select the correct type
of tyre. Tyres do, for example, have the following inscription on their walls:
205 / 60 R 15 91 V
What this means is:
The following speed restrictions apply to tyres. The
date of manufacture is also stated on the tyre wall (possibly only on the inside
of wheel):
DOT ... 20 04...
means, for example, that the tyre was manufactured in the 20th week of the year
2004.
Any spare wheel which differs from the tyres fitted to the vehicle (e.g. winter tyres
or low-profile tyres) should only be used only for a short time in the event of a
puncture and when adopting an appropriately cautious style of driving. It should be
replaced as quickly as possible by a normal wheel.
WARNING
•Only use those tyres or wheel rims which have been approved for your
model of Škoda Auto a.s. vehicle. Failure to observe this instruction will
adversely affect the road safety of your vehicle - risk of accident! Approval
and licencing of your vehicle on publ ic roads may also become void as a
result.
•You must on no account drive at a hi gher speed than is permissible for
your tyres - risk of an accident resulting from tyre damage and loss of control
over your vehicle.
•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.
•Never fit tyres which have already been used without having adequate
knowledge of their previous history. Ty res age even if they have not been
used at all or only very little. A spare tyre must only be used in exceptional
cases and only then when adopting an appropriately cautious style of
driving.
•Do not, where possible, replace indivi dual tyres but at least replace them
on both wheels of a given axle at the same time. Always fit the tyres with the
deeper tread depth to the front wheels.
For the sake of the environment
Old tyres must be disposed of in conf ormity with the appropriate regulations.
