in “Working in the engine compartment” on
page 225.
– Wait a few minutes and pull out the oil dipstick.– Wipe off the dipstick with a clea
n cloth and insert it again fully.
– Then withdraw the dipstick ag
ain and read off the oil level.
Oil level within range – You must
not
top up the oil.
Oil level within range –You
may
top up the oil. It is possible that the oil level may then be
within range after doing this.
Oil level within range –You
must
top up the oil
⇒
page 228. It is sufficient, once this is done,
to keep the oil level within range .
It is normal for the engine to consume oi
l. The oil consumption may be as much as
0.5 l/1 000 km depending on your style of driving and the conditions under which you operate your vehicle. The oil consumpt
ion may be slightly higher than this
during the first 5 000 kilometres. One should therefore check the oil level at regular intervals, preferably every time after the fuel tank is filled or after driving for long stretches. We recommend maintaining the oil level within the range -
but not above this
,
if the engine has been operating at hi
gh loads, for example during a lengthy
motorway trip during the summer months,
towing a trailer or negotiating a high
mountain pass. The warning light in the instrument cluster* will indicate
⇒page 35, “Engine oil
pressure

” whether the oil level is too low. In this case, check the oil level as soon
as possible. Top up with an appropriate quantity of oil.
Caution
•
The oil level must on no account ex
tend beyond the range . Danger of
damaging the cata
lytic converter.
•
Do not continue your journey
if for some reason it is not possible under the
conditions prev
ailing to top up with oil.
Switch of the engine and contact
and
obtain professional assistance from a specialist garage.

WARNING
•
Avoid dripping oil onto hot parts of the engine when topping up will oil -
a risk of fire!•
Read and observe the warning notes
⇒page 225, “Working in the engine
compartment” before working in the engine compartment.
For the sake of the environment
The oil level must on no account extend beyond the range
⇒page 227. Oil will
otherwise be drawn in through the crankc
ase ventilation and may pass through the
exhaust system to atmosphere. The oil ma
y combust in the cata
lytic converter and
damage it.Changing engine oilThe engine oil must be changed at the intervals stated in the Service schedule or according to the service interval indicator
⇒page 20, “Service Interval Display”.
WARNING
•
Only carry out the engine oil change, if you have the required profes-
sional knowledge!
•
Read and observe the warning notes
⇒page 225, “Working in the engine
compartment” before working in the engine compartment.•
Let the engine cool down - risk of burning from hot oil.
•
Wear an eye protection - risk of caustic burns due to oil splashes.
•
Oil is toxic! Store old oil in a safe place out of the reach of children and
unauthorized persons until you dispose of it properly.
Caution
You must not pour any additives into th
e engine oil - risk of engine damage!
Damage, which results from such produc
t, are excluded from the warranty.
For the sake of the environment
•
You must on no account pour oil into
the ground or into the sewage system.
•
In view of the problems involved in prop
erly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you have the oil and oil filter change carried out by an authorised Škoda Service Partner.
Note
After your skin has come in contact with the oil, you must thoroughly wash your skin.Cooling systemCoolant The job of the coolant is to cool the engine.The cooling system does not require an
y maintenance under normal operating
conditions. The coolant consis
ts of water with a concentration of coolant additive
of 40 %. This mixture not only provides

also protects the cooling and heating system from corrosion. It also prevents the formation of scale and significantly increases the boiling point of the coolant. You must therefore not reduce the concentr
ation of antifreeze agent in the coolant
by adding water, also not during the summ
er months or in countries with a warm
climate.
The concentration of coolant additive in the coolant must be at least
40%. You can increase the amount of antifreeze
in the coolant if a higher concentration
of antifreeze is necessary for climatic
reasons but only up to 60% (antifreeze
protection down to approx. -40°C). The an
tifreeze protection tails off above that
concentration. Vehicles exported to countries with a co
ld climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant wh
ich offers antifreeze protection down to
about -35°C. In these countries the concentr
ation of coolant additive should be at
least 50 %. Coolant The cooling system is factory-filled with co
olant (purple in colour), which complies
with the specification TL-VW 774 G. We recommend that you use the same c
oolant additive - G12 PLUS-PLUS (purple
in colour) for toppi
ng up the system.
Please contact an authorised Škoda Service Partner if you have any questions regarding the coolant or if you wish to fill up with a different coolant. An authorised Škoda Service Partner can al
so supply you with the correct coolant
additives.
Caution
•
Other coolant additives may cause operational problems which, in partic-
ular, involves significantly redu
cing the anticorrosion effect.
•
Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of th
is, result in major engine damage.
Inspecting the coolant levelThe coolant expansion bottle is loca
ted in the engine compartment on
the right. – Switch the engine off. – Open the bonnet
⇒
page 224.
– Check the level of coolant in the coolant expansion bottle
⇒
fig. 212
.
The coolant level when the engine is cold must lie between the (MIN) and (MAX) markings. The level may also rise slightly above the (MAX) marking when the engine is warm.
If the coolant level in the reservoir is too low, this is indicated by the warning light in the instrument cluster
⇒page 36, “Coolant temperat
ure/ Coolant quantity
”.
We nevertheless recommend in
specting the coolant level directly at the reservoir
from time to time. Loss of coolant A loss of coolant is first and foremost an
indication of a leak
in the system. You
should not merely top up the coolant in the
reservoir. It is also important to have
the cooling system inspected without delay by a specialist garage.

Losses can only occur through the pressure
relief in the cap of the coolant expan-
sion bottle which is completely free of leak
s if the coolant boils as a result of over-
heating and is forced out of the cooling system.
WARNING
Read and observe the warning notes
⇒page 225, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as soon as possible if the source of over-heating itself cannot be
determined and removed, since there may be grave
damage to the engine.Replenishing the coolant– Switch the engine off. – Allow the engine to cool down. – Place a cloth over the cap of the coolant expansion reservoir
⇒
page 229, fig. 212
and unscrew the cap
carefully
by turning it to the
left
⇒
.
– Top up the coolant. – Screw the cap tight until it is heard to lock.The coolant which you use for replenishing the system, must comply with one specific specification
⇒page 228. Do not use an alternative additive if the coolant
additive G12 PLUS is not available in exceptional cases. Just top up the system with water and as soon as possible arrange ad
justment to correct the mixing ratio of
water and coolant additive again by a specialist garage. Only use fresh coolant for topping up the system.
Do not fill up over the “MAX” marking! Excess coolant which is heated up is forced out of the cooling system through the pressure relief valve in the cap of the coolant compensation bottle. Wait until the engine has cooled down for a system which has suffered a major loss of coolant before pouring in coolant. This is necessary to avoid engine damage.
WARNING
•
The cooling system is pressurized! Do not open the cap of the coolant
expansion bottle if the engine is
still hot - risk of scalding!
•
The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to the health. It is important, therefore, to always safely store any coolant additive in its original container out of the reach of children - risk of poisoning!•
If any splashes of coolant get into yo
ur 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 conditions prevailing to top up with coolant. Switch of the engine and contact

and obtain professional assistance from a specialist garage.
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 comp
liance with environmental protection
regulations.

Radiator fan The radiator fan may switch on suddenly.The radiator fan is driven by an electr
ic motor and controlled according to the
coolant temperature. The radiator fan may continue running fo
r 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 beca
use of an accumulation of heat or
•
the warm engine compartment is heated
up additionally by
strong sunlight.
WARNING
You must therefore be aware when work
ing in the engine compartment that
the fan may switch on suddenly - risk of injury!Brake fluidInspecting the brake fluid level
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 224.
– Inspect the brake fluid level in the reservoir
⇒
fig. 213
. The level must
be between 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 br
ake pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid level 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
⇒page 40, “Brake
system
” lighting up in the instru
ment cluster. In this case
stop immediately and
do not drive any further! Obtain professional assistance.
WARNING
•
Read and observe the warning notes
⇒page 225, “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
further - risk of accident! Obtain professional assistance.Replacing brake fluidBrake 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. Th
e water content also lowers the boiling
point of the brake fluid.
This is why brake fluid must be replaced every two
years. One may only use new genuine brake fluid
from Škoda Auto. The specification for
the brake fluid is “FMVSS 116 DOT 4”.

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
prescribed distance from your vehicl
e while observing all national legal
provisions. 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 th
e vehicle from unexpectedly rolling away.
Note
Comply with the national legal regulations.Changing a wheelAlways change a wheel on a level surface as far as possible. – Take off the full wheel trim*
⇒
page 249 or the caps
⇒
page 249.
– In the case of light alloy wheels remove the wheel trim cap
⇒
page 250.
– First of all slacken the safety wh
eel bolt * and afterwards the other
wheel bolts
⇒
page 250.
– Jack up the vehicle until the wheel to
be changed is clear of the ground
⇒
page 251.
– 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, al
ternately and diagonally using the
wheel wrench* (crosswise) and last the safety wheel bolt* ⇒
page 250.
– Mount the full wheel trim/w
heel trim cap or the caps.
Note
•
All bolts must be clean
and must turn easily.
•
You must never grease or oil the wheel bolts!
•
When fitting on unidirectional tyres, ensure that the tyres rotate in the correct
direction
⇒page 238.
Subsequent stepsAfter changing the wheel, you must perform the following steps. – Stow and attach the replaced wheel in the spare wheel well. – Stow the vehicle tool kit in the space provided. –
Check
the
tyre pressure
on the spare wheel just mounted as soon as
possible.
– Have the
tightening torque
of the wheel bolts
checked
with a torque
wrench as soon as possible. Steel and light alloy wheels must be tight-ened to a tightening torque of
120 Nm
.
– Have the defective tyre repaired as soon as possible.

Driver of the towing vehicle – Do not drive off until the tow rope is taught. – Release the clutch particularly gent
ly when starting off or depress the
accelerator particularly gently if yo
ur vehicle is fitted with an auto-
matic gearbox.
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 wipers and wi
ndscreen 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 si
gnificantly greater physical force
to depress the brake pedal and to steer the vehicle if the engine is not running.
– Ensure that the tow rope is always kept taught.Tow rope or tow bar 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.
The tow rope must be elastic to protect
the vehicle. Thus one should only use
plastic fibre rope or a rope made
out of a similarly elastic material.
Only attach the tow rope to the
towing eyes
provided for this purpose
⇒page 254
and
⇒page 256.
Driving style Towing another vehicle requires a certain
amount of practice. Both drivers should
be familiar with the particular points
about towing a vehicle. Unskilled drivers
should not attempt to tow in another vehicle or to be towed in. 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 ro
pe or tow bar when you attempt to tow a
vehicle which is not standing on a paved road.
Caution
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.
Note
•
Please comply with any legal requirements particularly regarding the switched
on signal systems, when towing in
or tow-starting another vehicle.
•
The tow rope must not be twisted as it may in certain circumstances result in the
front towing eye being unscrewed out of your vehicle.Front towing eye The towing eye is stored in the box for the vehicle tool kit.
