Seat belts
Why seat belts?
It is a proven fact that seat belts offer good protection in accidents
⇒fig. 124 . Thus wearing a seat belt is a legal requirement in most coun-
tries.
Seat belts which have been correctly fastened and adjusted hold the
occupants of the car in the correct seated position ⇒fig. 124 . The belts
reduce the kinetic energy (energy of motion) to a considerable extent.
They also prevent uncontrolled movements which, in turn, may well result
in severe injuries.
The occupants of a vehicle who have fastened and correctly adjusted their
seat belt, profit to a major extent from the fact that the kinetic energy is
optimally absorbed by the belts. The structure of the front end of the
vehicle and other passive safety measures, such as the airbag system, also contribute to reducing the kinetic energy. The energy produced is
thus absorbed and there is less risk of injury.
Accident statistics prove that seat belts which are fastened and properly
adjusted reduce the risk of an injury and enhance the chance of survival
in a major accident
⇒page 146.
It is important that you pay attention to safety measures, particularly when
transporting children in the vehicle ⇒page 164, “Transporting children
safely”.
WARNING
•Fasten your seat belt each time before setting off, also when
driving in town! This also applies to the people seated at the rear -
risk of injury!
•Expectant women must also always wear a seat belt. This is the
only way of ensuring optimal protection for the unborn child
⇒ page 148, “Fastening a three-point seat belt”.
•It is important for the belt webbing to be properly routed if the
seat belts are to offer the maximum protection. You can see a
description of how safety belts should be fitted properly on the
next pages.
Note
Please comply with any differing legal requirements when using the seat
belts.

Monitoring the airbag system
The functionality of the airbag system is also monitored electronically,
when one airbag has been switched off
An airbag which has been switched off by a Škoda dealer using the
vehicle system tester:
•The warning light for the airbag system lights up for 3 seconds after
switching on the ignition and then flashes for 12 seconds afterwards in 2
second intervals.
Front passenger airbags switched off using the switch for front
passenger airbags* in stowage compartment on the front passenger
side:
•The airbag indicator light in the instrument cluster comes on for about
3 seconds each time the ignition is switched on.
•Switching off airbags is indicated in the middle of the dash panel by the
lighting up of the indicator light  ⇒ page 162.
Note
Your Škoda dealer will be able to advise you whether national legislation
in your country allows airbags in your vehicle to be deactivated, and which
ones.

The EDL switches on again automatically as soon as the brake has cooled
down.
WARNING
•Depress the accelerator carefully when accelerating on
uniformly slippery road surfaces, such as ice and snow. The driven
wheels might still spin despite the EDL and affect the stability of
the vehicle - risk of an accident!
•You should always adapt your style of driving to the condition
of road surface and to the traffic situation even when your vehicle
is fitted with EDL. The increased safety offered must not tempt you
to take greater risks than otherwise - risk of an accident!
Note
•If the ABS warning light comes on, this may also indicate a fault in the
EDL. Please have the vehicle inspected as soon as possible by a Škoda
dealer.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other
assignment of tyres and wheels) can influence the function of the EDL
⇒ page 233, “Accessories, changes and replacement of parts”.
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 necessary to have the thickness of the brake pads
inspected at a Škoda dealer between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under
certain conditions 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
possible (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 with road salt if
you have not used the brakes for some considerable time beforehand.
The layer of salt on the brake discs and brake pads must first be rubbed
off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on the 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 corrosion 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 Škoda dealer without delay in order to have the problem recti-
fied. 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.

Power steering
Power steering assists the driver in steering the vehicle and reduces the
physical force needed for steering.
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 Škoda dealer 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 210. The
correct hydraulic oil level is important for proper operation of the power
steering system.

Driving and the Environment
182
Driving and the Environment
The first 1 500 kilometres and then
afterwards
A new engine
The engine has to be run in during the first 1 500 kilome-
tres.
Up to 1 000 kilometres
– Do not drive faster than 3/4 of the mamimum speed of the gear
in use, that is 3/4 of the maximum permissible engine speed.
– Do not use full throttle.
– Avoid high engine revolutions.
– Do not tow a trailer.
From 1 000 up to 1 500 kilometres
– Increase the power output of the engine gradually up to the
full speed of the gear engaged, that is up to the maximum
permissible engine revolutions.
During the first operating hours the engine has higher internal friction than
later until all of the moving parts have harmonized. The driving style which
you adopt during the first 1 500 kilometres plays a decisive part in the
success of running in your car.
You should not drive at unnecessarily high engine revolutions even
after the running-in period is complete. The maximum permissible engine speed is marked by the beginning of the red zone on the scale of the revo-
lutions counter. Shift up into the next higher gear on a vehicle fitted with
manual gearbox before the red zone is reached.
Extremely high engine
revolutions are automatically governed, by the way.
For a vehicle fitted with a manual gearbox the converse situation also
applies: Do not drive at engine revolutions which are too low. Shift down
as soon as the engine is no longer running smoothly.
Caution
All the speed and engine revolution figures apply only when the engine is
at its normal operating temperature. Never rev up an engine which is cold,
neither when the vehicle is stationary nor when driving in individual gears.
For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a
higher gear as early as possible are ways to minimise fuel consumption
and operating noise levels and protects the environment.
New tyres
New tyres have to be “run in” since they do not offer optimal grip at first.
You should take account of this fact for the first 500 kilometres and drive
particularly carefully.

Driving and the Environment183
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
New brake pads
Allow for the fact that new brake pads do not achieve their full braking effi-
ciency until approximately 200 kilometres. 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 guideline also applies to any new brake pads installed at a future
date.
During the running-in period, you should avoid excessive stresses on the
brakes. This includes, for example, violent braking, particularly from very
high speeds, and also when crossing mountain passes.
Catalytic converter
Proper operation of the emission control system (catalytic
converter) is of major significance for driving your vehicle
in an environmentally conscious way.
Please refer to the following guidelines:
– For vehicles with petrol engine only refuel with unleaded petrol
⇒page 204, “Grades of petrol”.
– Never run the fuel tank completely empty.
– Do not switch off the ignition while you are driving the vehicle.
– Do not pour too much oil into the engine ⇒page 213,
“Replenishing engine oil”. – Do not tow-start the vehicle over a distance of more than 50
metres ⇒page 248, “Tow-starting a vehicle”.
If you drive your vehicle in a country in which unleaded petrol is not avail-
able, you must have the catalytic converter replaced later when driving the
vehicle into a country in which use of a catalytic converter is mandatory.
WARNING
•In view of the high temperatures which may be produced in the
catalytic converter, one should always park a vehicle in such a way
that the catalytic converter cannot come into contact with easily
flammable materials below the vehicle - a risk of fire!
•Never use additional underbody protection or corrosion-protec-
tion agents for the exhaust pipes, catalytic converters or heat
shields. Such substances might ignite when driving - risk of fire!
Caution
•Vehicles fitted with catalytic converter should never be allowed to let
the fuel tank to run completely empty. An irregular fuel supply can result
in poor ignition or misfiring. Unburnt fuel may get into the exhaust system
and damage the catalytic converter.
•Filling the tank even only once with leaded petrol will result in the cata-
lytic converter being destroyed.
•If you detect misfiring, a drop in performance or irregular engine
running when driving, reduce your speed immediately and have the
vehicle inspected by the nearest Škoda dealer. The symptoms described
may be caused by a fault in the ignition system. Unburnt fuel may get into
the exhaust system and damage the catalytic converter.

Driving in an economical and
environmentally conscious manner
General
Your personal style of driving is a major factor.
Your fuel consumption, any pollution of the environmental and the wear-
and-tear to the engine, brakes and tyres, depend essentially on three
factors:
•your personal style of driving
•the conditions under which your vehicle is operated
•technical aspects.
You can easily improve your fuel economy by 10 - 15 percent by driving
in an economical way with foresight. This section is intended to provide
you with a number of tips on how to protect the environment and at the
same time save money.
The fuel consumption can naturally also be influenced by factors which
are beyond the driver'scontrol. It is, for example, normal for the fuel
consumption to increase in winter and under worsened conditions such as
poor road conditions, towing a trailer, etc.
The technical requirements for low fuel usage and economic efficiency of
the vehicle have already been built into the vehicle at the works. Special
attention has been given to minimising negative effects on the environ-
ment. It is necessary to take note of the guidelines given in this chapter in
order to make best use of these characteristics and to maintain their
effectiveness.
Looking ahead when driving
A vehicle's highest fuel consumption occurs it accelerates.
Avoid accelerating and braking unnecessarily. If you drive with forsight
you will not need to brake so often and will also then not have to accel-
erate so much. Let your vehicle coast to a stop, for example, if this is
possible, when you see that the next set of traffic lights is at red.
Shifting gears and saving energy
Shifting up early saves on fuel.
Manual gearbox
– Drive no more than about one length of your vehicle in first gear. Shift up into the next higher gear at approx. 2 000 revs.

consumption in
litres/100 km. and
speed in km/h.

Driving and the Environment
188
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 must first have reached their optimal
operating temperature in order to effectively reduce fuel consumption
and pollutant emissions.
The cold engine vehicle consumes approx. 20 - 30 litres/100 km of fuel
immediately after starting. Fuel consumption drops to 15 litres/100 km
after just 1 kilometre. The engine reaches its operating temperature
(outside temperature and engine dependent) only after about 4 to 10 kilo-
metres 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. 154 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 consump-
tion means that it is worth taking a look in the luggage compartment to
avoid transporting any unnecessary ballast.
It is particularly in town trafffic, 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 conven-
ience, although you no longer need it. The increased aerodynamic drag of

Towing a trailer

Towing a trailer
Towing a trailer
Technical requirements
The towing device must satisfy certain technical require-
ments.
Your vehicle is designed primarily for transporting persons and luggage.
It can, however, also be used for towing a trailer - provided certain tech-
nical 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 power socket for the electrical connec-
tion between the vehicle and trailer. If the trailer which you wish to tow has
a 7-pin connector , you can use a suitable adapter cable. You can obtain
such an adapter from a Škoda dealer.
This work must be carried out in accordance with the manufacturer's
specifications if a towing device is retrofitted.
Škoda dealers 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 installed by a
Škoda dealer. 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 inclines 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 engine power output drops with
increasing height due to a lowering of air pressure and thus the ability 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 documents or in the brochure -
Technical Data .
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.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Tyre pressure
Select the tyre inflation pressure on your vehicle for that of “fully laden”,
⇒
page 226. 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 exterior mirrors fitted if you are not able to see
the traffic behind the trailer with the standard rear-view mirrors. Both exte-
rior mirrors 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 head-
lights. Alter the setting as necessary with the aid of the headlight beam
adjuster ⇒page 58.
Detachable ball head
The ball rod is detachable on vehicles which 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 192.
Note
•We recommend that you also have your 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 temperature gauge if the outside temperature 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/hour 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 immediately 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, then brake firmly. This will avoid brake jolts
resulting from the trailer wheels locking. Shift down gears in good time
