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 increase d to about 20 km/hour 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 27.
•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 193, “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

pedal firmly and hold it in this position in order to achieve the shortest possible braking distance.
The Brake Assist is able to help you achieve a shorter braking distance in emergency situations by rapidly producing the pressure required in the brake system. It fully exploits the attributes of the ABS. After you release the brake pedal, the function of the Brake Assist is automatically switched off and the brakes operate in the normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist function is also not available. Further information on the ESP ⇒page 145.
WARNING
•The Brake Assist is also not able to overcome the physical limits of your car in terms of the braking distance required.
•Adapt your speed to the conditions of the road surface and to the traffic situation.
•The increased safety offered by the Brake Assist must not tempt you to take a greater safety risk than otherwise.
Electrohydraulic power steering
The power steering enables you to steer the vehicle with less physical force.
The steering characteristics can be changed by a specialist garage.
You will place great stresses on the power st eering system if the steering is turned to full lock when the vehicle is stationary. Turning the steering to full lock in such a situation will be acco mpanied by noises.
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.
It is possible that the hydraulic pump of the power steering will not run due to the low vehicle network voltage if the battery has gone flat and the engine must started with the help off jump leads. This conditio n will be indicated by lighting up of the warning light.
The power steering operates again if the battery is charged to a specific range when engine is running. It also operates again, if the engine can be started with its own battery.
Caution
Do not leave the steering at full lock fo r more than 15 seconds when the engine is running - risk of damagi ng 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.
Tyre inflation pressure-control system*
The tyre inflation pressure-control system compares with the aid of the ABS sensors the speed and also the rolling circumference of the individual wheels. If the infla- tion pressure and therefore the rolling circumference of a wheel has changed signif- icantly, the warning light  lights up in the dash panel ⇒page 26. The tyre inflation pressure-control system function s late or too sensitively if:
•the structure of the tyre is damaged,
•the vehicle is loaded to one side or with a load on the roof,

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 kilometres.
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 approx.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 revolutions 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 figure s 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 fu el 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 efficiency 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 increa sing the pressure 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 drivin g your vehicle in an environmen-
tally conscious way.
Please refer to the following guidelines:
– For vehicles with petrol engine only refuel with unleaded petrol
⇒ page 170, “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 178, “Replenishing
engine oil”.
– Do not tow-start the vehicle over a distance of more than 50 metres
⇒ page 205, “Tow-starting a vehicle”.
If you drive your vehicle in a country in which unleaded petrol is not available, you must have the catalytic converter replaced later when driving the vehicle into a country in which use of a cata lytic 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-protection agents for the exhaust pipes, catalyti c 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 le aded petrol will result in the catalytic converter being destroyed.
•If you detect misfiring, a drop in perf ormance or irregular engine running when driving, reduce your speed immediately and have the vehicle inspected by the nearest specialist garage. The symptoms described may be caused by a fault in the ignition system. Unburnt fuel may get in to the exhaust system and damage the catalytic converter.
For the sake of the environment
Even if the exhaust system is operating properly, a sulphur-like exhaust odour may be produced under certain operating condit ions of the engine. This depends on the sulphur content of the fuel. It is often su fficient to refuel with unleaded premium- grade petrol of a different brand or at a different filling station.
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 en vironment and at the same time save money.

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 th e aid of the headlight beam adjuster ⇒ page 46.
Detachable ball head
The ball rod is detachable on vehicles with towing device and suppliable from Škoda original accessories. It is stowed together with separate fitting instructions in the spare wheel well in the luggage compartment of the vehicle.
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/hour for safety reasons. This also applies for coun- tries 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 engine speed when the outside temperature is very high ⇒page 10.
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 179, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 24, “Coolant temperature/coolant level ”.
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

Inspecting and Replenishing182
One may only use new genuine brake fluid from Škoda Auto a.s. The specification for the brake fluid is “FMVSS 116 DOT 4”.
We recommend that you have the brake fluid replaced by a Škoda Service Partner as part of an Inspection Service.
WARNING
•Using old brake fluid can result in seve re stress on the brakes because of the formation of vapour bubbles in the brake system. This greatly impairs the braking efficiency and thus also the safety of your vehicle.
•Brake fluid is toxic! It must therefore be kept safely in closed original containers and well aw ay from children and unauthorized persons.
Caution
Brake fluid damages the paintwork of the vehicle.
For the sake of the environment
In view of the problems involved with proper disposal of brake fluid, the special tools and the professional knowledge required, we recommend you have the brake fluid replaced by a Škoda Service Partner.
Battery
Working on the battery
The battery is located in the engine compartment below a plastic box.
– Unlock the interlock on the positive terminal side of the battery
⇒ fig. 161.
– Open the cover in direction of arrow.
– The installation of the battery cover on the positive terminal side takes
place in the reverse order.
Removal and installation of the battery is not recommended since it can, under certain circumstances, lead to major damage to the battery and fuse boxes. Contact a specialist garage.
There is a risk of injuries, scalding, acci dents and burns when carrying out any work on the battery and on the electrical system. For this reason, it is essential to comply with the warning instructions ⇒ stated below and with the general applicable rules of safety.
