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 204. The
correct hydraulic oil level is important for proper operation of the power
steering system.

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.

New brake pads
Allow for the fact that new brake pads do not achieve their full braking effi-
ciency until after the first 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:
– Always fill the fuel tank with unleaded petrol ⇒page 198,
“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 207,
“Replenishing engine oil”. – Do not tow-start the vehicle over a distance of more than 50
metres ⇒page 239, “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.
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.
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-
protection agents for the exhaust pipes, catalytic converters or
heat shields. Such substances might ignite when driving - risk of
fire!

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 0 - 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 about 2 000 revs.

Driving and the Environment

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 of a mid-range vehicle consumes 30 - 40 litres/100 km.
of fuel immediately after starting. Fuel consumption drops to 20 litres/100
km. after just 1 kilometre. The engine reaches its operating temperature
only after about four kilometres 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. 149 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
your vehicle causes it to use about 1 litre more fuel than normal at a speed
of 100 - 120 km/h, even when you are not carrying a load on the roof.

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.
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.
You can make full use of the permissible drawbar load indicated on the
ball head of the towing device, but you must not exceed this.
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.

Tyre inflation pressure
Select the tyre inflation pressure on your vehicle for that of “fully laden”,
⇒
page 220. 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 186.
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

before negotiating a downhill 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 downhill stretch in a low gear at a high engine speed
when the outside temperature is very high ⇒page 14. If the needle of the
coolant temperature gauge moves into the right-hand area or even the red
area of the scale, reduce your speed immediately. Stop and switch off the
engine if the warning light
 in the instrument cluster begins flashing.
Wait a few minutes and check the level of coolant in the coolant expansion
bottle ⇒page 208.
Please refer to the following guidelines ⇒page 31.
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 device 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
Note
•Do not carry out any modifications or repairs to the ball head or to any
other components on the towing device.
WARNING
•Do not use any aids or tools for installing or removing the ball
head. This might result in damage to the locking mechanism to the
extent that the safety of the towing device is no longer assured -
risk of an accident.

•Contact a Škoda dealer if you encounter any problems using the
device.
•Inspect the ball head to ensure that it is properly locked each time
before setting off.
•Never unlock the ball head with a trailer coupled to it.
•You should take off the ball head if you drive without towing a trailer.
Inspect whether the end cover properly seals off the mounting shaft.
•Remove the ball head beforehand if you wish to clean your vehicle
using a steam jet. Ensure that the end cover properly seals the mounting
shaft.
