created, where you can trade-in your vehicle. After you trade-in your vehicle, you will
receive a confirmation stating the recycling in accordance with environmental regula-
tions.
Vehicles with special built-on types
Technical documents regarding changes carried out on the vehicle must be kept by the
vehicle user, in order to hand over later to the old car user. This ensures the recycling
in accordance with en vironmental regulations.
Note
Detailed information about the trade-in and recycling of old cars is available from a
Škoda Service Partner.Motoring abroadGeneral
Other circumstances may exist abroad.It is also possible, in certai n countries, that the Škoda Service Partner network is limited
or has not been established yet. This is the reason why obtaining certain spare parts
may be somewhat complicated and specialist garage personnel may only be able to
make limited repairs. Škoda Auto in the Czech Republic and relevant importers are happy to provide information about technical
aspects of the vehicle, required mainte-
nance work and possibilities for getting repairs done.
Unleaded petrolA vehicle fitted with a petrol engine must always be refuelled with unleaded petrol
 page 196. The automobile associations can provide you with information regarding
the locations of filling stations which offer unleaded petrol.HeadlightThe low beam of your headligh ts is set asymmetrically. It illuminates the side of the
road on which you are driving to a greater ex tent. If you drive abroad on the other side
of the road, you will da zzle oncoming traffic.
In order to prevent the dazzling of oncoming tr affic, it is necessary that an adjustment
of the headlights is carried out by your auth orised Škoda Service Partner.
The adaptation of the headlights with Xe non lights* (applies to vehicles which are
designed for driving on the left and on the right) is performed in the menu Setup -
Tra v e l m o d e in the main menu of the information display* page 64, “Tourist
light”.Avoiding damage to your vehicleWhen driving on poor roads and lanes or when driving over kerbstones, steep ramps
etc., you must pay particular attention to ensuring that any low-slung parts of the
vehicle, such as spoiler and exhaust, do not touch the ground and get damaged.
This particularly applies to models with a lowered suspension (sport suspension) and
also when your vehicle is fully laden.

Driving through bodies of water on roadsIn order to avoid damage to the vehicle wh en driving through bodies of water (e.g.
flooded roads), observe the following:
Determine the depth of the water when driv ing through bodies of water. The water
can reach at the maximum the web on the lower sill of the vehicle fig. 177 .

Drive no more than at walking speed. At a higher speed, a water wave can form in
front of the vehicle which can cause water to penetrate into the air induction system of
the engine or into other parts of the vehicle.

Never let the vehicle stand in the water, never drive backwards and do not switch
off the engine.
WARNING

Driving through water, mud, sludge etc. can reduce the braking power and
extend the braking distance - risk of accident!

Avoid sudden and severe braking manoeuvres immediately after driving
through bodies of water.

After driving through bodies of water, the brakes must be cleaned and dried
as soon as possible by intermittent braking. Only apply the brakes for the
purpose of drying and cleaning the brake discs if the traffic conditions permit
this. Do not place any other road users in jeopardy.
Caution

When driving through bodies of water, pa rts of the vehicle such as the engine,
gearbox, catalytic converter, chassis or electrics can be severely damaged.

Oncoming vehicles can generate water waves which can exceed the permissible
water level for your vehicle.

Potholes, mud or rocks can be hidden under the water making it difficult or impos-
sible to drive through the body of water.

Do not drive through salt water. The salt can lead to corrosion. Immediately rinse
all the parts of the vehicle, which came into contact with the salt water, with fresh
water.Note
After driving through a body of water, we recommend that the vehicle is checked by a
specialist garage.

Technical Data
Headlights
Before starting off with a hitched trailer, also check the setting of the headlights. Alter
the setting as necessary with the aid of the headlight beam adjuster
page 65, “Head-
lamp range adjustment* ”.
Detachable ball head
The ball rod is detachable on vehicles which feature a factory-fitted towing device. It is
stowed together with separate fitting instru ctions in the spare wheel well in the luggage
compartment of the vehicle.
Further information on the towing device page 204.
Note

We recommend that you also have your vehicle inspected between service inter-
vals if you tow a trailer frequently.

The handbrake on the towing vehicle must be put on when coupling and decou-
pling 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 temperature gauge if the outside temperature 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 combina-
tion.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for countries
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 cond
itions, particularly near accident black
spots.
You must always reduce your speed immediat ely 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 downhill
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 engi ne speed when the outside temperature is
very high  page 16, “Coolant temperature gauge”.
If the needle of the coolant temperature gauge moves into the right-hand area or even
the red area of the scale, reduce your speed immediately. Stop and switch off the
engine if the warning light
 in the instrument cluster begins flashing. Wait a few
minutes and check the level of coolant in the coolant expansion bottle page 220,
“Inspecting the coolant level”.
Please refer to the following guidelines  page 32, “Coolant temperature/ Coolant
quantity ”.
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 of the
engine speed. One should also not drop a gear for this reason when towing a trailer as
long as the engine can manage th e slope without any drop in speed.

Underbody protectionThe underside of your vehicle is protected for life against chemical and mechanical
influences.
One cannot, however, completely rule out damage to the protective layer when
driving so we recommend that you inspect the protective layer on the underside of
your vehicle and on the chassis at certain intervals - this is best done at the beginning
and end of the winter - and to touch up any damaged areas.
The authorised Škoda Service Partners have suitable spray products available as well
as the necessary equipment and are familiar with the instructions for use. It is therefore
best to have such touch-up work or additional corrosion protection measures carried
out by an authorised Škoda Service Partner.
WARNING
Never use additional underbody protection or corrosion-protection agents for
the exhaust pipes, catalytic converters, di esel particle filter or heat shields.
When the engine reaches its operating temperature, these substances might
ignite - risk of fire!Protection of hollow spacesAll the cavities of your vehicle which are at risk from corrosion are protected for life by
a layer of protective wax applied in the factory.
This wax protection does not require to be inspected or re-treated. Please remove any
small amount of wax which flows out of the cavities at high temperatures with a plastic
scraper and clean the spot using petroleum cleaner.
WARNING
Safety and environmental pr otection regulations should observed when using
petroleum cleaner to remove wax - a risk of fire!
Engine compartmentGood corrosion protection is very importan t, particularly in winter when one often
drives over its salt-strewn roads. One should therefore clean the whole engine
compartment before and after the salt spreading period and treat with preservative in
order to prevent the salt from being destructive.
The authorised Škoda Service Partners have the cleaning agents and preservatives
recommended by the manufacturer and also the required equipment.
WARNING

It is necessary to observ e the guidelines given in the chapter before working
on the engine compartment page 216, “Working in the engine compart-
ment”.

Let the engine cool down before cleaning the engine compartment.Caution

Engine cleaning may be only be un dertaken when the ignition is off.

It is recommended to cover the generator before washing the engine compart-
ment.For the sake of the environment
The dirty water produced by washing the engine has washed away petrol, and residues
of grease and oil and should therefore be cleaned by an oil separator. This is why
engine washing should only be undertaken in a specialist garage or at a fueling station
(when these are fitted with the required equipment).Care of the interior of vehiclePlastic parts, artificial leather and clothsYou can clean plastic parts and artificial leather with a moist cloth. You should only
treat such parts with special solvent-free plastic cleaning and care products it does
prove to be adequate.

Fuel
212
FuelPetrolGrades of petrolYour vehicle can only be operated with unleaded petrol, which complies with the
standard EN 228. The individual grades of petrol are distinguished by their octane
number (RON). On the inside of the fuel filler flap, you will find the information
regarding the RON required by your engine page 213, fig. 179 .
Prescribed fuel - unleaded petrol 95/91 RON
Use unleaded petrol 95 RON. You can also use unleaded petrol 91 RON, but this leads
to a slight loss in performance.
If, in case of necessity, the vehicle must be refuelled with petrol of a lower octane
number than the one prescribed, you must co ntinue driving at medium engine speeds
and low engine load. Driving at high engine speeds or a high engine load can severely
damage the engine! Refuel as soon as possib le with petrol of the prescribed octane
number.
Prescribed fuel - unleaded petrol min. 95 RON
Use unleaded petrol 95 RON.
In case of necessity, you can refuel with petrol 91 RON if petrol 95 RON is not avail-
able. You must continue driving at medium engine speeds and minimum engine load.
Driving at high engine speeds or a high engine load can severely damage the engine!
Refuel as soon as possib le with petrol of the prescribed octane number.
Even in case of necessity, you must not use petrol of a lower octane number than 91,
otherwise the engine can be severely damaged!
You can find further information on refuelling page 213.
Unleaded petrol with higher octane number
You can make unlimited use of unleaded pe trol which has a higher octane number
than the one prescribed. On vehicles with prescribed unleaded petrol
95/91 RON, the use of petrol with a
higher octane number than 95 does not result in a noticeable power increase or a
lower fuel consumption.
On vehicles with prescribed unleaded petrol min. 95 RON, the use of petrol with a
higher octane number than 95 does not result in a power increase or a lower fuel
consumption.
Caution

All Škoda vehicles with petrol engines are equipped with a catalytic converter and
must be only driven with unleaded petrol. Fi lling the tank even only once with leaded
petrol will result in the cata lytic converter being destroyed!

Only use unleaded petrol which complies with the standard EN 228.

If you use petrol with a lower octane num ber than the one prescribed, the engine
can be severely damaged!Note
The handling, performance and life of your engine are determined to a significant
extent by the quality of the fuel. Do not use any petrol additives.DieselDiesel fuelYour vehicle can only be operated with diesel fuel, which complies with the standard
EN 590 (standard DIN 51628 in Germany, standard ÖNORM C 1590 in Austria).
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and similar prod-
ucts) in diesel fuel.
You can find information on refuelling page 213.

Caution

Therefore, your vehicle can only be operated with diesel fuel which complies with
the standard EN 590 (standard DIN 51628 in Germany, standard ÖNORM C 1590 in
Austria). Filling the tank even only once wi th diesel fuel which does not comply with
the standard, can result in damage to the engine parts, the lubrication system, the fuel
and exhaust system.

If by mistake you have refuelled with a different fuel other than the diesel fuel
which complies to the above mentioned standards (e.g. petrol), do not start the engine
or switch on the ignition! This can result in severe engine damage! Contact a specialist
garage and have the fuel sy stem of the engine cleaned.

Water which has collected in the fuel fi lter can result in engine problems.

Your vehicle is not adapted for use of biofue l (RME), therefore this fuel must not be
refuelled and driven. The use of biofuel (RME) can lead to damage to the engine or the
fuel system.
Operation in winterWinter-grade diesel fuel
A different grade of diesel fuel is available at filling stations in winter than during the
summer. Using “summer-grade diesel fuel” at temperatures below 0°C can result in
operational problems because th e diesel becomes viscous as a result of paraffin sepa-
ration.
It is therefore the case that the standard EN 590 (standard DIN 51628 in Germany,
standard ÖNORM C 1590 in Austria) is the diesel fuel class prescribed for certain
periods of the year which can also be purc hased at the corresponding time during the
year. “Winter-grade diesel fuel” will still operate properly even at a temperature of -
20°C.
It is often the case in countries with different climatic conditions that diesel fuels avail-
able have a different temperature characteristic. The authorised Škoda Service Part-
ners and filling stations in the country concer ned will be able to provide you with infor-
mation regarding the diesel fuels available.
Prewarming fuel
The vehicle is fitted with a fuel filter prewarming system. This secures operation of a
vehicle using diesel fuel down to an environmental temperature of -25°C.
Caution
It is not permitted to add the various fuel additives on the market, including petrol, to
diesel fuel in order to improve its flow properties.RefuellingFig. 179 Right rear side of the ve hicle: Open fuel filler flap / fuel filler flap with cap unscrewedThe filler flap is automatically unlocked or locked with the central locking.Opening the fuel filler cap– Press onto the left side of the fuel filler flap fig. 179 - left.

Fuel
214WARNING
Pay attention to any legal requirements if you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for
safety reasons. The canister can be damaged in the event of an accident and fuel
may leak out.
Caution

Before refuelling it is necessary to switch off the auxiliary heating system (auxiliary
heating and ventilation) *.

Remove any fuel which has spilled onto th e paintwork of your vehicle immediately
- risk of paint damage!

On vehicles fitted with a catalytic converte r, never let the fuel tank run completely
empty. An irregular supply of fuel to the engine can result in misfiring and unburnt fuel
may get into the exhaust system, which may result in overheating and damage to the
catalytic converter.

Make sure that the valve is not pressed into the filler tube when inserting the pump
nozzle into the filler tube. Otherwise you are unintentiona lly filling up the volume,
which in case of heat can cause an expansion of the fuel. This can lead to an overflow
of fuel or damage to parts of the fuel reservoir.

The fuel tank is full just as soon as th e pump nozzle switches off for the first time,
provided the nozzle has been operated prop erly. Do not continue refuelling - other-
wise the expansion volume is filled up.Note
The fuel tank has a capacity of about 60 litres, containing a reserve of 10.5 litres.s3fg.2.book Page 214 Friday, April 30, 2010 12:17 PM
