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.

WARNING
•The battery acid is strongly corrosive and must, therefore, be handled with the greatest of care. Always we ar protective gloves, eye and skin protection when handling batteries. Corrosive fumes in the air irritate the air passages and lead to conjunctivitis and inflammation of the air passages in the lungs. Battery acid corrodes dental enamel and creates deep wounds after contact with the skin which take a long time to heal. Repeated contact with diluted acids causes skin diseases (inflammations, ulcers, slin cracks). Acids coming into contact with water are diluted accompanied by significant development of heat.
•Do not tilt the battery otherwise battery electrolyte may flow out of the battery vent openings. Prot ect the eyes with safety glasses or a shield! There is the danger of suffering blindness! If any battery electrolyte gets into your eye, rinse out your eye immediately with clear water for several minutes. Contact a doctor without delay.
•Splashes of acid on your skin or clothes should be neutralised as soon as possible using soap suds and then rinsed with plenty of water. Contact a doctor immediately if you swallow battery electrolyte.
•Keep batteries out of the reach of children.
•Hydrogen is released when you char ge a battery and a highly explosive gas mixture is produced. An explosion can be caused through sparkling over during unclamping or loosening of the cable plug while the ignition is on.
•Bridging of the poles will create a short circuit (e.g. through metal objects, cables). Possible consequences of a short circuit: Melting of lead struts, explosion and burning of the battery, jets of acid spurting out.
•It is prohibited to work with a naked flame and light, to smoke or to carry out any activities which produce sparks. Avoid creating sparks when working with cables and electrical device s. Strong sparking represents a risk of injury.
•Before carrying out any work on the electrical system, switch off the engine, the ignition as well as all electrical components and disconnect the negative cable (-) on the battery. If you wish to replace a bulb it is sufficient to switch off the appropriate light.
•Never charge a frozen or thawed battery - risk of explosion and caustic burns! Replace a frozen battery.
•Never use a battery which is damaged - risk of explosion! Immediately replace a damaged battery.
Caution
•You must only disconnect the battery if the ignition is switched off, otherwise the electrical system (electronic components) of the vehicle may be damaged. When disconnecting the battery from the el ectrical system of the vehicle, first disconnect the negative terminal (-) of th e battery. Then disconnect the positive terminal (+).
•When reconnecting the battery, first conne ct the positive terminal (+) and only then the negative terminal (-) of the batt ery. You must on no account connect the cables wrongly - risk of a cable fire.
•Ensure that battery acid does not come into contact with the vehicle body otherwise damage could occur to the paintwork.
•Do not place the battery in direct daylight in order to protect the battery housing from the effects of ultra-violet light.
For the sake of the environment
A removed battery is a special type of waste which is harmful to the environment - we recommend that you contact your Škod a Service Partner regarding disposing of the battery.
Note
•Please also refer to the guidelines ⇒page 185, “Disconnecting and recon- necting the battery”, also after connecting the battery.

Battery with a charge level indicator, the so-called magic eye*
There is a so-called magic eye ⇒fig. 162 located on the top of the battery. The “magic eye” changes its colour in line with the charge state of and electrolyte level in the battery.
Air bubbles can influence the colour of th e “magic eye”. For this reason carefully knock on the “magic eye” before carrying out the check.
•Green colour - the battery is adequately charged.
•Dark colour - the battery has to be charged
•Colourless or yellow colour - we reco mmend you have the battery checked by a Škoda Service Partner.
Batteries, which are more than 5 years old, must be replaced. We recommend you have the electrolyte level inspected and adjusted to the correct level or the battery replaced if necessary by a Škoda Service Partner.
Caution
If the vehicle has not been driven for more than 3 to 4 weeks, the battery will discharge because certain electrical comp onents consume electricity (e.g. control units) also in idle state. You can prevent the discharging of the battery by discon- necting the negative terminal or charging the battery constantly with a very low charging current. Please also refer to the notes when working on the battery ⇒ page 182, “Working on the battery”.
Inspecting the electrolyte level
The battery is practically maintenance-free under normal operating conditions. We do, however, recommend that you have the electrolyte level inspected from time to time by a Škoda Service Partner when outside temperatures are high or when driving on long trips. You should also check the electrolyte level ⇒page 184 each time the battery is charged.
The battery acid level will also be ch ecked as part of the Inspection Service.
Operation in winter
The battery has to provide greater amounts of electricity during the winter. It also has only part of the initial power output at low temperatures that it has at normal temperatures.
A discharged battery may already freez e at temperatures just below 0°C.
We therefore recommend that you have the battery checked by a Škoda Service Partner before the start of the winter, and recharged if necessary.
Charging the battery
A properly charged battery is essential for reliably starting the
engine.
– Read the warning notes ⇒ in “Working on the battery” on
page 182 and ⇒.
– Switch the ignition and all electrical components off.
– Only for “quick-charging” : Disconnect both battery cables (first of all
“negative”, then “positive”).
– Carefully attach the terminal clam ps of the charger to the battery
terminals (red = “positive”, black = “negative”).
– You can now plug the mains cable of the charger into the power socket
and switch on the charger.

– When charging is completed: switch the charger off and unplug the
mains cable from the power socket.
– Only then should you disconnect the terminal clamps of the charger.
– Reconnect the cables to the battery (first of all “positive”, then “nega-
tive”).
It is not normally necessary to disconnect the cables of the battery if you recharge the battery using low ampera ges (as for example from a mini-charger). Please also refer to the instructions from the charger manufacturer.
A charging current of 0.1 of the total batter y capacity (or lower) is that which should be used until full charging is achieved.
It is, however, necessary to disconnect both cables before charging the battery with high amperages, so-called “ quick-charging”.
“Quick-charging” a battery is dangerous ⇒ in “Working on the battery” on page 182. It requires a special charger an d appropriate knowledge. We therefore recommend that you have your battery qu ick-charged only by your Škoda Service Par tner.
A discharged battery may already freeze at temperatures just below 0°C ⇒. We recommend that you no longer use a ba ttery which has thawed out because the casing of the battery may be cracked through the formation of ice and this would allow battery electrolyte to flow out.
The vent plugs of the battery should not be opened for charging.
WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic burns! Replace a frozen battery.
Disconnecting and reconnecting the battery
On disconnecting and reconnecting the batte ry the following functions are initially deactivated or are no longer able to operate fault-free.
We recommend having the vehicle checked by a Škoda Service Partner to ensure full functionality of all electrical systems.
Replacing the battery
You should only replace a battery with a new battery of the same capacity, voltage (12 V), amperage and of the same size. Škoda Service Partners have a range of suit-able batteries available.
We recommend that you only have an ol d battery disposed of by your Škoda Service Partner since it does require special disposal.
For the sake of the environment
Batteries contain pois onous substances such as sulphuric acid and lead. They must be disposed of in accordance with loca l environmental protection regulations and on no account as domestic waste.

Breakdown assistance202
We recommend that you always carry the adapter for the wheel bolts with you in the vehicle. It should be st owed in the vehicle tool kit.
Caution
•Damage can occur to the adapter and safety wheel bolt if the safety wheel bolt is tightened up too much.
•On steel wheels, the theft-deterrent wheel bolt must always be installed in the hole, which is close to the valve. Otherwise the full wheel trim cannot be mounted and the full wheel trim can be damaged during the assembly.
Note
The set of safety wheel bolts can be obtained from a Škoda Service Partner.
Jump-starting
Initial steps
You can use the battery of another vehicle for jump-starting yours if the engine does not start because the battery on your vehicle is flat. You will require jump-start cables for this purpose.
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the battery supplying the power must not be significa ntly less than the capacity of the discharged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and insu- lated terminal clamps. Plea se pay attention to the manufacturer's instructions.
Positive cable - colour coding in the majority of cases red.
Negative cable - colour coding in the majority of cases black.
WARNING
•A discharged battery may already freeze at temperatures just below 0°C. In case of frozen battery carry out no jump-starting - risk of explosion! Also after thawing of the battery there is a risk of caustic burns due to leaking acid. Replace the frozen battery.
•Please pay attention to the warning instructions relating to working in the engine compartment ⇒page 174.
Note
•There must not be any contact between the two vehicles otherwise current may flow as soon as the negative terminals are connected.
•The discharged battery must be proper ly connected to the system of the vehicle.
•Switch off any installed telephone and also pay attention to the instructions for use of the telephone in such a situation.
•We recommend purchasing jump-start cabl es from Škoda Service Partners as a Škoda original accessory or from retailers who sell branded batteries.
Start engine
It is important to connect the jump-start cables in the correct order.
