Brakes
What has a negative effect on braking efficiency?
Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions
of the vehicle and your style of driving. Particularly if you drive a great deal in towns
and over short distances or if you adopt a sporty style of driving, it may be neces-
sary to have the thickness of the brake pads inspected at a specialist garage
between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain condi-
tions such as when driving through water, during heavy rain showers or after the
vehicle has been washed in an automatic vehicle wash, since the brake discs and
brake pads may be moist or even have a coating of ice on them in winter. You
should dry the brakes as soon as possib le (by applying and releasing the brakes
several times, if the road conditions and the traffic situation allows it).
There also may be a certain delay before the full braking efficiency is available when
driving on roads which have been treated wi th road salt if you have not used the
brakes for some considerable time beforeha nd. The layer of salt on the brake discs
and brake pads must first be rubb ed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on th e bake pads occur if the vehicle has been
parked for a long period and if you do not make much use of the braking system.
We recommend cleaning the brake discs by firmly applying the brakes at a fairly
high speed if you do not make much use of the braking system or if surface corro-
sion is present ⇒.
Faults in the brake surface
If you notice that the braking distance has suddenly become longer and that the
brake pedal can be depressed further, it is possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist garage
without delay in order to have the problem rectified. Drive at a reduced speed while
on your way to the dealer and adapt your style of driving to the higher brake pedal
pressure required. Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The
level of the brake fluid is monitored electronically
⇒page 29, “Brake system ”.
WARNING
•Only apply the brakes for the purpos e of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users
in jeopardy.
•When retrospectively mounting a front spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced
otherwise the braking sy stem could run too hot.
•Allow for the fact that new brake pads do not achieve their full braking
efficiency until approximately 200 kilo metres. 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 pres-
sure on the brake pedal. This guidelin e also applies to any new brake pads
installed at a future date.
Caution
•Never allow the brakes to ru b by applying slight pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a longer
braking distance and excessive wear.
•Before negotiating a steep downhill sect ion, please reduce your speed, shift
down into the next lower gear (manual ge arbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of the
vehicle and reduces the strain on the brakes . Any additional braking should be done
intermittently, not continuously.
Brake booster
The brake booster boosts the pressure which you generate with the brake pedal.
The necessary pressure is only gene rated when the engine is running.

WARNING
•Never switch off the engine before the vehicle is stationary.
•The brake booster only operates when the engine is running. Greater
physical effort for braking is required when engine is switched off. Because
if you do not stop as normal, this can cause an accident and severe injuries.
Antilock brake system (ABS)
ABS prevents the wheels locking when braking.
General
The ABS contributes significan tly to enhancing the active safety of your vehicle.
Compared to a car not fitted with the ABS brake system, you are able to retain
optimal steering ability even during a fu ll brake application on a slippery road
surface because the wheels do not lock up.
You must not expect, however, that the br aking distance will be shorter under all
circumstances as a result of the ABS. Th e braking distance for example on gravel
and fresh snow, when you should anyway be driving slowly and cautiously, will be
longer.
Operating principle
As soon as the vehicle speed has increa sed to about 6 km/h an automatic test
procedure is conducted during which you wi ll be able to hear a pumping noise for
about 1 second.
The brake pressure will be reduced on a wheel which is rotating at a speed which is
too low for the speed of the vehicle and tend ing to lock. This control cycle is notice-
able from a pulsating movement of the brake pedal which is accompanied by
noises. This is consciously intended to pr ovide the driver with the information that
the wheels are tending to lock (ABS control range). You must always keep the brake
pedal depressed to enable the ABS to optima lly control the brake application in this
braking range. Never interrupt the application of the brakes!
WARNING
•The ABS can also not overcome the physic al limits of your vehicle. Please
do not forget this, particularly when driv ing on icy or wet road surfaces. If the
ABS is operating within the control ra nge, adapt your speed immediately to
the conditions of the road surface and the traffic situation. The increased
safety offered by the ABS must not tempt you to take greater risks than
otherwise - risk of an accident!
•The normal braking system is still fully functional if there is an ABS fault.
Visit a specialist garage as quickly as po ssible and adjust your style of driving
to take account of the ABS fault in the meantime since you will not know how
great the damage is.
Note
•A warning light comes on if a fault occurs in the ABS system ⇒page 29.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign-
ment of tyres and wheels) can in fluence the function of the ABS ⇒page 205,
“Accessories, changes and replacement of parts”.
Brake Assist*
During a severe brake application (e.g. if a hazard exists), the Brake Assist increases
the braking force and thus makes it possible to rapidly produce the pressure
required in the brake system.
The majority of drivers do apply the brakes in good time in dangerous situations,
but do not depress the brake pedal with suff icient pressure. Consequently, it is not
possible for the car to achieve its maxi mum deceleration and the car covers a
greater distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In such
cases, a much greater braking pressure ex ists than during a normal brake applica-
tion. This makes it possible, even with a relatively low resistance of the brake pedal,
to produce an adequate pressure in the brake system in the shortest possible time,
which is required for maximum deceleration of the car. You must apply the brake

⇒ 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.

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.

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!

WARNING
It is particularly important that you do not clean tyres with circular spray
jets. Visible but also invisible damage to tyres may occur even at a relatively
large spraying distance and if sprayed only for a short time - risk of accident!
Caution
The water containing wax must be no hott er than 60°C, otherwise the vehicle can
be damaged.
Wax treatment
Good wax treatment is an effective way of protecting the paintwork from harmful
environmental influences an d minor mechanical damage.
The vehicle must be treated with a high-qua lity hard wax polish at the latest, when
no more drops form on the clean paintwork.
A new layer of a high-quality hard wax polish can be applied to the clean bodywork
after it has dried thoroughly. Even if you use a wax preserver regularly we still
recommend that you treat the paintwork of the vehicle at least twice a year with
hard wax.
Caution
Never apply wax to the windows.
Polishing
Polishing is only necessary if the paintwor k of your vehicle has become unattractive
and if it is no longer possible to achieve a gloss with wax preservers.
You must treat the paintwork with a wax preserver if the polish you use does not
contain any preserving elements ⇒page 175, “Wax treatment”.
We recommend using a preservative from Škoda genuine accessories offered by
your Škoda dealer.
Caution
•You must not treat mat painted parts or plastic with polishing products or hard
wax.
•Do not polish the paintwork of the vehicle in a dusty environment, otherwise
the paintwork can be scratched.
Chrome parts
First clean the chrome parts with a damp clotch and then polish them with a soft,
dry cloth. If it does not prove to be adequate, use a chrome care product from
Škoda original accessories.
Caution
Do not polish the chrome parts in a du sty environment, otherwise they can be
scratched.
Paint damage
Slight damage to paintwork such as scratche s, scuffs or traces of chip damage must
be touched up immediately with paint (Škoda painting pen) before any corrosion
can result. You can of course have this wo rk carried out by a Škoda Service Partner.
Škoda Service Partners have a range of matching touch-up pens or spray cans
available in the colo ur of your vehicle.
The paint number of the original paintwor k of your vehicle is indicated on the
vehicle data sticker ⇒page 227.
Any corrosion which has already have formed must be removed thoroughly. Apply
a corrosion protection primer and then the paint to the affected point. You can of
course have this work carried out by a Škoda Service Partner.

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!

Engine compartment
Good corrosion protection is very importan t, particularly in winter when one often
drives over its salt-strewn roads. One should therefore clean the entire engine
compartment before and after the salt spreading period, in order to prevent the salt
from being destructive.
Škoda Service Partners have the cleani ng agents recommended by the manufac-
turer and also the required equipment.
WARNING
•It is necessary to observe the guidelines given in the chapter before
working on the engine compartment ⇒page 185.
•Let the engine cool down before cleaning the engine compartment.
Caution
•Engine cleaning may be only be und ertaken when the ignition is off.
•It is recommended to cover the generator before washing the engine compart-
ment.
For the sake of the environment
The dirty water produced by washing the engine has washed away petrol, and resi-
dues of grease and oil and should therefor e be cleaned by an oil separator. This is
why engine washing should only be undertaken in a garage or at a fueling station
(when these are fitted with the required equipment).
Care of the interior of vehicle
Plastic parts, artificial leather and cloths
You can clean plastic parts and artificial leather with a moist cloth. You should only
treat such parts with special solvent-free plastic cleaning and care products it
does prove to be adequate. Upholstery cloth and cloth trim on the
doors, luggage compartment cover, head-
liner etc. are best treated with special cleaning products, using if necessary a dry
foam and a soft sponge or brush.
We recommend using a cleaning product from Škoda genuine accessories offered
by your Škoda dealer.
Caution
Solvent-free cleaners attack the material and can damage it.
Fabric covers of electrically heated seats
Do not clean the seat covers moist as this may result in damage to the seat heating
system.
Clean such covers using special agents, for example dry foam.
Natural leather
Natural leather requires quite particular care and attention.
Leather should be treated from time to time according the following
guidelines depending on how much it is used.
Normal cleaning
– Clean soiled areas of the leather with slightly moistened cotton or
woollen cloth.
Severe soiling
– Clean severely soiled areas with a cloth dipped in a mild soapy solu- tion (2 spoonfuls of natural soap to 1 litre of water).
– Ensure that the leather is not soaked through at any point and that no water gets into the stitching of the seams.
– Dry off the leather with a soft, dry cloth.

– After this, once again withdraw the dipstick and read off the oil level ⇒page 187, fig. 175 .
Oil level within range
– You must not top up the oil.
Oil level within range
–You may top up the oil. It is possible that the oil level may then be
within range after doing this.
Oil level within range
–You must top up the oil ⇒page 188. It is sufficient, once this is done,
to keep the oil level is within range .
It is normal for the engine to consume oil. The oil cons umption may be as much as
0.5 l/1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. The oil consumpt ion may be slightly higher than this
during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time
after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range if the engine has been
operating at high loads, for example during a lengthy motorway trip during the
summer months, towing a trailer or negotiating a high mountain pass, but not
above this .
The warning light in the instrument cluster will indicate whether the oil level is too
low ⇒page 27, “Engine oil ”. In this case, check the oil level as soon as possible.
Top up with an approp riate quantity of oil.
WARNING
Read and observe the warning notes ⇒page 185, “Working in the engine
compartment” before working in the engine compartment.
Caution
•The oil level must on no account ex tend beyond the range . Danger of
damaging the catalytic converter.
•Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with oil. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe engine
damage.
Replenishing engine oil
– Inspect the oil level ⇒page 187.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 186,
“Engine oil specifications”.
– Inspect the oil level ⇒page 187.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
WARNING
•Avoid dripping oil onto hot parts of the engine when topping up will oil -
a risk of fire!
•Read and observe the warning notes ⇒page 185, “Working in the engine
compartment” before working in the engine compartment.
For the sake of the environment
The oil level must on no account be above the range ⇒page 187, fig. 175. Oil
will otherwise be drawn in through the cr ankcase ventilation and may pass through
the exhaust system to atmosphere. The oi l may combust in the catalytic converter
and damage it.
