Working in the engine compartment
Particular care is required when carrying out any work in the en-
gine compartment!
There is a risk of injuries, scalding, accidents and fire when working in the en-
gine compartment, e.g. inspecting and replenishing oil and other fluids. For this
reason, it is essential to comply with the warning instructions stated below and
with the general applicable rules of safety. The engine compartment of your car
is a hazardous area ⇒
  .
WARNING
● Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scalding! Wait long enough until the steam
or coolant has stopped escaping.
● Switch off the engine and pull out the ignition key.
● Apply the handbrake firmly.
● If your vehicle is fitted with a manual gearbox, move the gearshift lever in-
to Neutral, or if it is fitted with automatic gearbox, move the selector lever in-
to position

P.
● Allow the engine to cool down.
● Keep children clear of the engine compartment.
● Do not touch any hot engine parts - risk of burns!
● Never spill oil and other fluids over the hot engine. Such fluids (e.g. the an-
tifreeze contained in the coolant) may ignite!
● Avoid short circuits in the electrical system - particularly on the battery.
● Never place your hand into the radiator fan as long as the engine is still
warm. The fan might suddenly start running!
● Never open the cap of the coolant expansion reservoir so long as the en-
gine is still warm. The cooling system is pressurized!
● Cover over the cap of the reservoir with a large cloth when opening it as
protection for your face, hands and arms from hot steam or hot coolant.
● Do not let objects, such as e.g cleaning cloth or tools lie in the engine com-
partment. WARNING (Continued)
● 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 en-
gine 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.
Please 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 car-
rying 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 ac-
count mixed up. This may result in major operating problems and also vehicle
damage!  181

Check engine oil level The dipstick indicates the level of oil in the engine.
Fig. 151 Dipstick
Checking the oil level
– Ensure that the vehicle is positioned on a level surface and the engine has
reached its operating temperature.
– Switch the engine off.
– Open the bonnet ⇒  in Working in the engine compartment on page 181.
– Wait a few minutes until the engine oil flows back into the oil sump. Take out
the dipstick.
– Wipe off the dipstick with a clean cloth and insert it again fully.
– Then withdraw the dipstick again and read off the oil level.
Oil level within range A –
You must not top up the oil.
Oil level within range B –
You may top up the oil. It is possible that the oil level may then be within
range A after doing this.
Oil level within range C –
You must top up the oil ⇒  page 183. It is sufficient, once this is done, to keep
the oil level within range B .

Inspecting and Replenishing

WARNING (Continued)
● If any splashes of coolant get into your eyes, rinse out your eyes immedi-
ately with clear water and contact a doctor as soon as possible.
● You should also consult a doctor without delay if you have inadvertently
swallowed coolant. CAUTION
Do not continue your journey if for some reason it is not possible under the condi-
tions prevailing to top up with coolant. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe en-
gine damage. For the sake of the environment
Do not re-use coolant if it is necessary to drain the coolant in the system. It should
be collected and disposed of in compliance with environmental protection regula-
tions. 
Radiator fan The radiator fan may switch on suddenly.
The radiator fan is driven by an electric motor and controlled according to the
coolant temperature.
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 compartment that
the fan may switch on suddenly - risk of injury! Brake fluid
Inspecting the brake fluid level Fig. 153 Engine compartment: Brake flu-
id reservoir
The brake fluid reservoir is located on the left of the engine compartment. 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 ⇒ page 180 .
– Inspect the brake fluid level in the reservoir ⇒
 fig. 153 . The level must be be-
tween the “MIN” and “MAX” markings.
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 lev-
el drops significantly within a short time or if it drops below the “MIN” marking. If
the brake fluid level is too low, this is indicated by the warning light lighting up in
the instrument cluster ⇒ page 28, Brake system . In this case stop immediately
and do not drive any further! Obtain professional assistance. WARNING
● Read and observe the warning notes ⇒
 page 181, Working in the engine
compartment before working in the engine compartment.
● If the fluid level has dropped below the MIN marking, do not drive any fur-
ther - risk of accident! Contact a Škoda dealer to obtain professional assis-
tance. 186
Inspecting and Replenishing

Replacing brake fluid
Brake fluid absorbs moisture. This causes the fluid to absorb moisture from the
surrounding air over a period of time. Excessive water in the brake fluid may be
the cause of corrosion in the brake system. The water content also lowers the
boiling point of the brake fluid.
Only new genuine brake fluid from
ŠKODA may be used.
The brake fluid must comply with one of the following standards or specifications:
● VW 50114
● FMVSS 116 DOT4
● DIN ISO 4925 CLASS 4
We recommend that you have the brake fluid replaced by an authorised ŠKODA
Service Partner as part of an Inspection Service. WARNING
Using old brake fluid can result in severe 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. CAUTION
Brake fluid damages the paintwork of the vehicle. For the sake of the environment
Due to issues with disposal, the special tools and knowledge required, we recom-
mend you have the brake fluid replaced by an authorised ŠKODA Service Partner.
Battery General information Improper handling of the vehicle battery can cause damage. We therefore recom-
mend you have work on the vehicle battery carried out by an authorised
ŠKODA
service partner. There is a risk of injuries, scalding, accidents 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 ap-
plicable rules of safety. WARNING
● The battery acid is strongly corrosive and must, therefore, be handled with
the greatest of care. Always wear 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 in-
to 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. Protect 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. Con-
tact 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. If acid was
swallowed, seek immediate medical attention.
● Keep batteries out of the reach of children.
● Hydrogen is released when you charge a battery and a highly explosive gas
mixture is produced. An explosion can be caused through sparkling over dur-
ing 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, explo-
sion 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 devices. Strong sparking represents a risk of injury.
● Before carrying out any work on the electrical system, switch off the en-
gine, the ignition as well as all electrical components and disconnect the neg-
ative cable (-) on the battery. If you wish to replace a bulb it is sufficient to
switch off the appropriate light. £ 187

WARNING
● Only use those tyres or wheel rims which have been approved for your
model of ŠKODA vehicle. Failure to observe this instruction will adversely af-
fect the road safety of your vehicle - risk of accident! Approval and licensing of
your vehicle on public roads may also become void as a result.
● You must on no account drive at a higher speed than is permissible for
your tyres - risk of an accident resulting from tyre damage and loss of control
over your vehicle.
● Tyres which are 6 years old or more should only be fitted in exceptional ca-
ses and when adopting an appropriately cautious style of driving.
● Never fit tyres which have already been used without having adequate
knowledge of their previous history. Tyres age even if they have not been
used at all or only very little. A spare tyre must only be used in exceptional ca-
ses and only then when adopting an appropriately cautious style of driving.
● Do not, where possible, replace individual tyres but at least replace them
on both wheels of a given axle at the same time. Always fit the tyres with the
deeper tread depth to the front wheels. For the sake of the environment
Old tyres must be disposed of in conformity with the appropriate regulations. Note
It is not normally possible to fit wheels from other models of cars for technical
reasons. This may also apply in certain circumstances to the wheels of the same
type of vehicle. 
Wheel bolts Wheels and
wheel bolts are matched to each other in terms of design. Each time
you fit other wheels - e.g. light alloy wheels or wheels with winter tyres - you
must therefore also use the matching wheel bolts of the correct length and shape
of spherical cap. This is essential to ensure that the wheels are tightly fitted and
that the brake system operates properly.
If you retrofit wheel trims (or have this done), please also ensure that an ade-
quate flow of air remains assured for cooling the brake system.
Authorised

ŠKODA Service Partners are instructed in the technical possibilities
which exist regarding converting or retrofitting tyres, wheels and wheel trims. WARNING
● In case of incorrect treatment of the wheel bolts, the wheel can loosen
when the car is moving - risk of accident!
● The wheel bolts must be clean and must turn easily. However, they must
never be treated with grease or oil.
● If the wheel bolts are tightened to a too low tightening torque, the rim can
come loose when the car is moving - risk of accident! A tightening torque
which is too high can damage the bolts and threads and this can result in per-
manent deformation of the contact surfaces on the rim. CAUTION
The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm. 
Winter tyres The handling of your vehicle will be significantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber
blend, tread pattern). This particularly applies to vehicles which are equipped with
low-profile tyres
or high-speed tyres (code index H or V on wall of tyre).
Winter tyres must be mounted on all four wheels to obtain the best handling
characteristics.
You must only fit those types of winter tyre which are approved for your vehicle.
The permissible sizes of winter tyres are stated in your vehicle documents. Ap-
provals may differ because of national legislation.
Please remember that the tyres should be inflated to 20

kPa (0.2 bar) more than is
the case for summer tyres ⇒ page 192.
Winter tyres no longer offer the same winter performance once the tyre tread has
worn down to a depth of about 4 mm.
Ageing also causes winter tyres to lose most of their winter performance proper-
ties - even in cases where the remaining tread depth is still clearly more than 4
mm.
Speed restrictions apply to winter tyres as well as to summer tyres ⇒ page 194,
⇒  .

Before removing the spare wheel, you must take out the box with the vehicle tool
kit box ⇒ fig. 162 .
One should check the inflation pressure in the spare wheel (at best when general-
ly checking the tyre air pressures - see sign on the fuel filler flap ⇒ page 192) to
ensure that the spare wheel is always ready to use.
Temporary spare wheel
A warning label displayed on the rim of the temporary spare wheel indicates that
your vehicle is equipped with a temporary spare wheel.
Please observe the following notes when driving with a temporary spare wheel:
● The warning label must not be covered after installing the wheel.
● Do not drive faster than 80 km/h with this spare wheel and pay particular at-
tention while driving. Avoid accelerating at full throttle, sharp braking and fast
cornering.
● The inflation pressure for this spare wheel is identical to the inflation pressure
of the standard tyres. The temporary spare wheel R 18 must have an inflation
pressure of 420
kPa (4.2 bar)!
● Use this spare wheel only to reach the nearest specialist garage as it is not in-
tended for continuous use.
● No other summer or winter tyres must be mounted on the rim of the spare
wheel R 18. 
Changing a wheel Preliminary work The following steps should be carried out before actually changing the wheel.
– If it is necessary to change a wheel, park the vehicle as far away as possible
from the traffic flow. The place you choose should be level.
– Have all the occupants get out. While changing a tyre, the occupants of the
vehicle should not stand on the road (instead they should remain behind a
crash barrier).
– Apply the handbrake firmly.
– Engage 1st gear or if your vehicle is fitted with an automatic gearbox, position
the selector lever into position P .
– If a trailer is coupled, uncouple it. –
Take the vehicle tool kit ⇒ page 199
and the spare wheel ⇒ page 199 out of
the luggage compartment. WARNING
● If you find yourself in flowing traffic switch on the hazard warning lights
system and place the warning triangle on the side of the road at the prescri-
bed distance from your vehicle. Comply with the national legal regulations. In
this way you are protecting not only yourself but also other road users.
● Never start the engine with the vehicle sitting on the raised jack - danger
of suffering injury. CAUTION
If you have to change a wheel on a slope first block the opposite wheel with a
stone or similar object in order to secure the vehicle from unexpectedly rolling
away. Note
Comply with the national legal regulations. 
Changing a wheel Always change a wheel on a level surface as far as possible.
–
Take off the full wheel trim ⇒ page 201
or the caps ⇒ page 201.
– In the case of light alloy wheels remove the wheel trim cap ⇒
 page 202.
– First of all slacken the safety wheel bolt and afterwards the other wheel bolts
⇒  page 202.
– Jack up the vehicle until the wheel to be changed is clear of the ground
⇒ page 203.
– Unscrew the wheel bolts and place them on a clean surface (cloth, paper, etc.).
– Take off the wheel.
– Fit on the spare wheel and tighten the wheel bolts slightly.
– Lower the car.
– Tighten the wheel bolts firmly, alternately and diagonally using the wheel
wrench (crosswise) and lastly the wheel safety bolt ⇒

Jump-starting in vehicles with the “START-STOP” system
Fig. 172 Jump-starting on vehicles with
the START-STOP system
On vehicles with the “START STOP” system, the negative cable of the charger
must never be connected directly to the negative pole of the vehicle battery, but
only to the engine earth ⇒ fig. 172. 
Towing the vehicle General Vehicles with manual transmission can be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
Vehicles with automatic transmission can be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged!
Vehicles with four-wheel drive can be towed in with a tow bar or a tow rope or
with the front wheels raised.
A tow bar
is safest way of towing a vehicle and also minimizes any shocks. You
can use a tow rope only if a suitable tow bar is not available.
Refer to the following guidelines when towing:
Driver of the towing vehicle
– Release the clutch particularly gently when starting off or depress the acceler-
ator particularly gently if your vehicle is fitted with an automatic gearbox.
– On vehicles with manual transmission, only push down on the accelerator ped-
al once the rope is taught. The maximum towing speed is
50 km/h.
Driver of the towed vehicle
– Switch the ignition on so that the steering wheel is not blocked and you can
also operate the turn signal lights, the headlight flasher, the windscreen wip-
ers and windscreen washer system.
– Take the vehicle out of gear or move the selector lever into position N if your
vehicle is fitted with an automatic gearbox.
Note that the brake servo unit and power steering only operate if the engine is
running. You will require significantly greater physical force to depress the brake
pedal and to steer the vehicle if the engine is not running.
When using a tow rope, always ensure that the tow rope is always kept taught. CAUTION
● Do not tow start the engine - danger of damaging the engine. On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage or destroy the catalytic converter. You can
use the battery of another vehicle as a jump-start aid ⇒ page 206, Jump-starting
.
● If the gearbox of your vehicle no longer contains any oil because of a defect,
your vehicle must only be towed in with the driven wheels raised clear of the
ground, or on a special vehicle transporter or trailer.
● The vehicle must be transported on a special vehicle or trailer if it is not possi-
ble to tow in the vehicle in the way described or if the towing distance is greater
than 50

km.
● To protect both vehicles when tow-starting or towing, the tow rope should be
elastic. Thus one should only use plastic fibre rope or a rope made out of a similar-
ly elastic material.
● One should be constantly vigilant not to allow impermissibly high towing
forces or jerky loadings. There is always a risk of excessive stresses and damage
resulting at the points to which you attach the tow rope or tow bar when you at-
tempt to tow a vehicle which is not standing on a paved road.
● Attach the tow rope or the tow bar only to the towing eyes provided for this
purpose ⇒ page 209

, Front towing eye and ⇒ page 210, Rear towing eye. £208
