•There must not be any other persons (e.g. children) or animals
between the car occupant and the deployment area of the head
airbag. In addition, none of the occupants should lean their head
out of the window when driving, or extend their arms and hands out
of the window.
•The sun visors must not be swivelled to the side windows into
the deployment area of the head airbags if any objects, such as
ball-point pens etc. are attached to them. This might result in inju-
ries to the occupants if the head airbag is deployed.
•Installing impermissible accessories in the area of the head
airbags may considerably impair the protection offered by the head
airbag in the event of it being deployed. When the deployed head
airbag is inflated, parts of the accessories fitted may in certain
circumstances be thrown into the interior of the car and cause inju-
ries to the occupants ⇒ page 243, “Accessories, changes and
replacement of parts”.
•Any work on the head airbag system including installing and
removing system components because of other repair work (e.g.
removing headliner) must only be carried out by a specialist
garage.
Deactivating an airbag
Deactivating airbags
If any airbags have been deactivated, switch them on
again as soon as possible so that they are able to again
provide their proper protection.
There is the technical means installed within your vehicle to switch off the
front, side or head airbag (take out of commission).
This is why you should have the deactivation of the airbags carried out by
a specialist garage.
On vehicles equipped with the switch for deactivation of the airbags, you
can deactivate the front and side passenger airbag by means of this
switch ⇒page 172.
Deactivation of airbags is envisaged only for particular instances,
such as if:
•you must in exceptional cases use a child seat on the front
passenger seat where the child has its back to the direction of travel of the
vehicle (in some countries this must be in the direction of travel due to
other legal regulations applying) ⇒page 174, “Important safety informa-
tion on using child safety seats”
•you are not able to maintain the distance of at least 25 cm between
middle of steering wheel and chest, despite the driver seat being correctly
adjusted,
•special attachments are required in the area of the steering wheel
because of a physical disability,
•you have installed other seats (e.g. orthopaedic seats without side
airbags).

Electronic stability programme (ESP)*
General
General
The ESP aids you maintain control of your vehicle in situations in border-
line driving situations such as when negotiating a curve too fast. The risk
of skidding is reduced and your car thus offers greater driving stability
depending on the conditions of the road surface. This occurs at all speeds.
The following systems are integrated into the electronic stability
programme:
•Electronic Differential Lock (EDL),
•Traction control system (TCS),
•Antilock brake system ABS,
•Brake Assist.
Operating principle
The ESP switches on automatically when the engine is started and then
conducts a self-test. The ESP control unit processes data from the indi-
vidual systems. It also processes additional measurement data which are
supplied by highly sensitive sensors: the rotational velocity of the vehicle
about its vertical axis, the lateral acceleration of the vehicle, the braking
pressure and the steering angle.
The direction which the driver wishes to take is determined based on the
steering angle and the speed of the vehicle and is constantly compared
with the actual behaviour of the vehicle. If differences exist, such as the
car beginning to skid, the ESP will automatically brake the appropriate
wheel.
The car is stabilised again by the forces which take effect when the wheel
is braked. Intervention into the brake system takes place primarily on the
outer front wheel of a vehicle which tends to oversteer (tendency for the
rear of the vehicle to break away) while occurs this is on the inner rear
wheel of a vehicle which tends to understeer (tendency to shift out of the
curve). This braking control cycle is accompanied by noises.
The ESP operates in combination with the ABS ⇒page 189, “Antilock
brake system (ABS)”. If there is a fault in the ABS system, the ESP also
does not operate.

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 37,
“Brake system ”.
WARNING
•Only apply the brakes for the purpose 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 system could run too hot.
•Allow 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 fric-
tion 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.
Caution
•Never allow the brakes to rub 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 section, please reduce your
speed, shift down into the next lower gear (manual gearbox) 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 generated 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 significantly 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 full brake application
on a slippery road surface because the wheels do not lock up.
You must not expect, however, that the braking distance will be shorter
under all circumstances as a result of the ABS. The braking distance for
example on gravel and fresh snow, when you should anyway be driving
slowly and cautiously, will be longer.

Power steering
Power steering assists the driver in steering the vehicle and reduces the
physical force needed for steering.
The steering characteristics can be changed by a specialist garage.
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 the steering is turned to full lock when the car is stationary, you will
place great stresses on the power steering system. Turning the steering
to full lock in such a situation will be accompanied by noises. In addition,
the idling speed of the engine will drop briefly.
Caution
Do not leave the steering at full lock for more than 15 seconds when the
engine is running - risk of damaging the power steering!
Note
•Have the steering inspected as soon as possible by a specialist garage
if there is a leak or fault in the system.
•The power steering requires a special hydraulic oil. The oil reservoir is
located at the front left of the engine compartment ⇒page 220. The
correct hydraulic oil level is important for proper operation of the power
steering system.

Taking care of your vehicle and cleaning the vehicle
210
WARNING
One should remember when cleaning the wheels that moisture, ice
and road salt may adversely affect braking efficiency - 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 cause premature
wear of the steering. It is therefore important to clean dirty wheels.
Underbody protection
The underside of your vehicle 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 intervals - this
is best done at the beginning and end of the winter - and to touch up any
damaged areas.
Škoda dealers have suitable spray products available as well as the
necessary equipment and are familiar with the instructions for its use. It is
therefore best to have such touch-up work or additional corrosion protec-
tion measures carried out by a Škoda dealer.
WARNING
Never use additional underbody protection or corrosion-protection
agents for the exhaust pipes, catalytic converters or heat shields.
Such substances might ignite when driving - 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 remove wax - a risk of fire!
Engine compartment
Good corrosion protection is very important, 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 dealers have the cleaning agents and preservatives recommended
by the manufacturer and also the required equipment.
WARNING
•It is necessary to observe the guidelines given in the chapter
before working on the engine compartment ⇒page 219.
•Let the engine cool down before cleaning the engine compart-
ment.

Inspecting and Replenishing
220
•If you wish to work under the vehicle, you must secure the
vehicle from rolling away and support it with suitable supporting
blocks: the car jack is not sufficient for this - risk of injury!
•In cases where it be necessary to carry out inspection work
when the engine is running there is an additional risk from rotating
parts (e.g. the V-ribbed belt, alternator, radiator fan) and from the
high-voltage ignition system. Pl ease observe in addition the
following:
−Never touch the electrical cables of the ignition system.
− Absolutely avoid any jewellery, loose items of clothing or
long hair from getting into the rotating parts of the engine -
Hazard! Therefore remove any jewellery beforehand, tie up your
hair and wear tight fitting clothing.
•Please also comply with the warning instructions stated below
when carrying out any essential work on the fuel system or on the
electrical system:
−Always separate the car battery from the electrical system.
− Do not smoke.
− Never carry out any work close to naked flames.
− Always keep a working fire extinguisher at hand.
Caution
When replenishing fluids in the engine, always ensure that the fluids are
on no account mixed up. This may result in major operating problems and
also vehicle damage!

The radiator fan may continue running for up to 10 minutes after the
engine has been switched off - even if the ignition is also off. It may also
switch on suddenly after a certain time, if
•the coolant temperature has risen because of an accumulation of heat
or
•the warm engine compartment is heated up additionally by strong
sunlight.
WARNING
You must therefore be aware when working in the engine compart-
ment that the fan may switch on suddenly - risk of injury!
Brake fluid
Inspecting the brake fluid level
You can also see the location of the brake fluid reservoir in the
engine compartment from the general view of the engine
compartment ⇒page 220. The brake fluid reservoir on right-
hand steering models is positioned on the other side of the
engine compartment.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compart-
ment” on page 219.
– Pull off the rubber seal ⇒fig. 173 partially away and lift the
cover slightly.
– Inspect the brake fluid level at the reservoir . The level must be between the “MIN” and “MAX” markings. The markings are
indicated on the side of the reservoir.
A slight drop in the fluid level results when driving due to normal wear-and-
tear and automatic adjustment of the brake pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the
fluid level drops significantly within a short time or if it drops below the
“MIN” marking. A situation where the brake fluid level is too low is indi-
cated by the warning light
 lighting up in the instrument cluster
⇒ page 37. In this case stop the car immediately and do not drive any
further! Contact a Škoda Dealer to obtain professional assistance.
WARNING
•Read and observe the warning notes ⇒page 219, “Working in
the engine compartment” before working in the engine compart-
ment.

Wheels and Tyres
236
Tyre life
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 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. 179 . The inflation pressures for winter tyres are
20 kPa (0.2 bar) higher than those for summer tyres ⇒page 240.
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. 180 . It is not necessary to unscrew the valve extensions in
order to check and alter the inflation pressure of the tyre.
Always check the inflation pressure of tyres 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 influ-
ences 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.
