Engine oil
Engine oil specifications
The grade of engine oil should be selected in accordance with
precise specifications.
The engine of your vehicle has been factor y-filled with a high-grade oil which you
can use throughout the year - except in extreme climatic regions.
You can mix various oils together with each other when refilling with oil. This does
not, however, apply for models with flexible service intervals (QG1).
Engine oils are, of course, undergoing co ntinuous further development. Thus the
information stated in this Owner's Manual is only correct at the time of publication.
Škoda Service Partners are informed by Škoda Auto a.s. about current changes. This
why you should always have engine oil changed by your Škoda Service Partner.
The specifications (VW standards) stated in the following must be indicated sepa-
rately or together with other specifications on the bottle.

– After this, once again withdraw the dipstick and read off the oil level ⇒page 187, fig. 175 .
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 188. It is sufficient, once this is done,
to keep the oil level is within range .
It is normal for the engine to consume oil. The oil cons umption 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 if the engine has been
operating at high loads, for example during a lengthy motorway trip during the
summer months, towing a trailer or negotiating a high mountain pass, but not
above this .
The warning light in the instrument cluster will indicate whether the oil level is too
low ⇒page 27, “Engine oil ”. In this case, check the oil level as soon as possible.
Top up with an approp riate quantity of oil.
WARNING
Read and observe the warning notes ⇒page 185, “Working in the engine
compartment” before working in the engine compartment.
Caution
•The oil level must on no account ex tend beyond the range . Danger of
damaging the catalytic converter.
•Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with oil. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe engine
damage.
Replenishing engine oil
– Inspect the oil level ⇒page 187.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 186,
“Engine oil specifications”.
– Inspect the oil level ⇒page 187.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
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 185, “Working in the engine
compartment” before working in the engine compartment.
For the sake of the environment
The oil level must on no account be above the range ⇒page 187, fig. 175. Oil
will otherwise be drawn in through the cr ankcase ventilation and may pass through
the exhaust system to atmosphere. The oi l may combust in the catalytic converter
and damage it.

General comments
•New tyres do not offer optimal grip at first and should therefore be run in for
about 500 km at a moderate speed and an appropriately cautious style of driving.
You will also profit from longer tyre life.
•The tread depth of new tyres may differ because of design features and the
configuration of the tread (depending on the type of tyre and the manufacturer).
•Drive over curbs on the side of the road and other such obstacles slowly and,
where possible, at a right angles in order to avoid damage to tyres and wheel trims.
•Inspect your tyres from time to time for damage (punctures, cuts, splits and
bulges). Remove foreign bodies from the tyre profile.
•Damage to tyres and wheels is frequent ly not visible. Unusual vibrations or
pulling of the vehicle to one side could be a sign of tyre damage. Please reduce
your speed immediately and stop if you suspect that a wheel is damaged.
Inspect the tyres for signs of damage (bulge s, splits, etc.) If no visible damage is
present, please drive at an appropriatel y slow speed and carefully to the nearest
specialist garage in order to have your vehicle inspected.
•Also protect your tyres from contact with oil, grease and fuel.
•Immediately replace any dust caps of the valves which have got lost.
•Mark wheels before removing them so th at their previous direction of running
can be maintained when mounted them again.
•Always store wheels or tyres which been removed in a cool, dry and, where
possible, dark place. Tyres which are not fixed to a wheel trim should be stored
upright.
Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of the tyre. This
indicates the direction of rotation of the tyre, and it is essential that the tyres are
fitted on to run in this direction. Only then are the tyres able to provide the optimal
properties in terms of grip, low noise, wear-and-tear and aquaplaning. Further information concerning
the use of unidirectional tyres ⇒page 204.
WARNING
•New tyres during the first 500 km do not offer optimal grip and should
therefore be run appropriately - risk of accident!
•Never drive with damaged tyres - risk of accident!
Note
Please observe the various differing legal requirements regarding tyres.

Ty re l i fe
The life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened considerably if the tyres are insufficiently
or over-inflated and this will have an advers e effect on the handling of your vehicle.
Correctly inflated tyres are of particular importance when travelling at high speeds .
It is therefore good to check the pressure at least once a month and also before
setting off on a long trip. Please do not forget the spare wheel when checking the
tyres. The tyre inflation pressures for summer tyres are indicated on the inside of the fuel
filler flap
⇒fig. 183 . The inflation pressures for winter tyres are 20 kPa (0.2 bar)
higher than those for summer tyres ⇒page 203.
The tyre pressure should be at the highest pressure specified for your vehicle at all
times.
On cars with full wheel trim, valve extensions are fitted in place of dust caps
⇒ fig. 184 . It is not nece ssary to unscrew the valve extensions in order to check and
alter the inflation pressure of the tyre.
Always check the inflation pressure of ty res when cold. Do not reduce the higher
pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if your
vehicle is carrying a signi ficantly higher payload.
Driving style
Fast cornering, sharp acceleration and brak ing (squealing tyres) increase wear-and-
tear on your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influences
when driving which may result in an imbalance and which makes themselves felt
through vibration in the steering.
You should have the wheels rebalanced since any imbalance increases wear-and-
tear on the steering, the suspension and tyres. A wheel must also be rebalanced
when a new tyre is fitted and each time a tyre is repaired.
Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-and-tear
on the tyres but will also has an adverse effect on vehicle safety. Contact your
specialist garage if you no tice any unusual tyre wear.
WARNING
•If the inflation pressure is too low, the tyre must perform a greater flexing
work. At higher speeds the tyre will warm up as a result of this. This can
result in tread separation and even a tyre blowout.
•Immediately replace the damaged rims or tyres.

For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption.
Wear indicators
The base of the tread of the original tyres has wear indicators 1.6 mm high, installed
at right angles to the direction of travel. These wear indicators are located at 6 - 8
points depending on the make and are evenly spaced around the circumference of
the tyre ⇒fig. 185 . Markings on the walls of the tyres through the letters “TWI”,
triangular symbols or other symbols identify the position of the wear indicators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the
wear indicators, means that your tyres have reached their legally permissible
minimum tread depth.
WARNING
•You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn do wn. The legally permissible minimum
tread depth should be observed.
•Worn tyres do not provide the necessary adhesion to the road surface at
high speeds on wet roads. One could experience “aquaplaning” (uncon-
trolled movements of the vehicle - “swimming” on a wet road surface).
Changing wheels around
If significantly greater wear is present on the front tyres, we recommend changing
the front wheels around with the rear wheels as shown in the diagram ⇒fig. 186 .
You will then obtain approximately the same life for all the tyres.
It may be advantageous to swap the tyre s over “crosswise” when certain types of
wear characteristic arise on the running surface of the tyres (but not in the case of
unidirectional tyres). Škoda Service Pa rtners can provide you with details.
We recommend that you change the wheels around every 10 000 km in order to
achieve even wear on all wheels and to obtain optimal tyre life.
New tyres and wheels
Tyres and wheel rims are important design elements. One should therefore use the
tyres and wheel rims which have been released for use by Škoda Auto. They are
exactly matched to the vehicl e type and therefore contribu te significantly to good
road holding and safe driving characteristics ⇒ .
Only fit radial tyres of the same type on all 4 wheels, size (rolling circumference)
and, if possible, the same tread pattern on one axle.
The Škoda Service Partners have access to the most current information about
which tyres we have released for use on your vehicle.

WARNING
You must on no account drive your car at more than the permissible
maximum speed for your winter tyres - risk of an accident resulting from
tyre damage and loss of control over your car.
For the sake of the environment
Fit your summer tyres on again in good time since summer tyres offer you better
grip and handling on roads which are free of snow and ice as well as ar tempera-
tures below 7 °C - the braking distance is shorter, there is less tyre noise, tyre wear
is reduced and fuel consumption is reduced.
Note
Please observe the various differing legal requirements regarding tyres.
Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of the tyre .
This indicates the direction of rotation of th e tyre, and it is essential that the tyres
are fitted on to run in this direction. Only then are the tyres able to provide the
optimal properties in terms of grip, lo w noise, wear-and-tear and aquaplaning.
Should it be necessary to fit on a spare wheel in exceptional cases with a tyre not
dedicated to the running direction or in o pposite running direction, please adopt a
cautious style of driving as the tyre is no longer able to provide optimal grip and
handling in such a situation. This particul arly important on wet roads. Please refer
to the notes ⇒page 209, “Spare wheel”.
You should have the defective tyre replac ed as soon as possible and restore the
correct direction of rotation on all tyres
Snow chains
Snow chains can be used only for wheel sizes 6J x 16 ET 40 or 6J x 16 ET 37. Your
Škoda Service Partner can provide you with more detailed information. Snow chains must only be mounted on the front wheels.
When driving on wintry roads, snow chains
improve not only traction, but also the
braking performance.
Only use fine-link snow chains . They must not project more than 15 mm -
including the chain lock.
Remove the full wheel trims if you wish to fit snow chains to the wheels.
Observe the national legal requirements relating to the maximum vehicle speed
with snow chains.
WARNING
Please pay attention to the information in the supplied fitting instructions of
the snow chain manufacturer.
Caution
You must take the chains off as soon as you drive on roads which are free of snow.
They adversely affect the handling of your vehicle, damage the tyres and are rapidly
destroyed.
Note
We recommend that you use snow chains from the Škoda genuine accessories.

Spare wheel
The spare wheel is stowed in the spare wheel well in the luggage
compartment below the floor covering.
The spare wheel lies in a well in the luggage compartment under floor covering and
is fixed in place using special screws ⇒fig. 191 .
One should check the inflation pressure in the spare wheel (at best when generally
checking the tyre air pressures - see sign on the fuel filler flap ⇒page 200) to
ensure that the spare wheel is always ready to use.
Temporary spare wheel*
If you have such tyres on your vehicle, please refer to the notes below:
•The spare wheel provided with a car fitted with unidirectional tyres has different
dimensions. The wheel is provided with a warning sticker.
•After fitting on the wheel, the warning st icker must not be concealed (e.g. by the

•The inflation pressure for this spare wheel is identical to the inflation pressure
of the standard tyres.
•Use this spare wheel only to reach the nearest specialist garage as it is not
intended for continuous use.
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 wheel, the occu-
pants of the vehicle should not stan d on the road (e.g. 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 and the spare wheel ⇒ page 209 out of the
luggage compartment.
