CAUTION
● The starter may only be operated (ignition key position 3 ), if the engine is not
running. If the starter is immediately operated after switching off the engine, the
starter or the engine can be damaged.
● Avoid high engine revolutions, full throttle and high engine loads as long as
the engine has not yet reached its normal operating temperature - risk of damag-
ing the engine!
● 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.For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the
pollutant emissions are lower.
Petrol engines These engines are fitted with a starter system which selects the correct fuel-air
mixture for every external air temperature.
●
Do not operate accelerator before and when starting engine.
● Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt.
● It is possible that the fuse on the electrical fuel pump is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒ page 211.
● Contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator
after the engine has started.
Diesel engines Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside temper-
ature.
The preglow indicator light comes on after the ignition has been switched on. You should not switch on any major electrical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.
● You should start the engine immediately after the glow plug warning light
has gone out.
● The glow plug warning light will come on for about one second if the engine is
at a normal operating temperature or if the outside temperature is above +5 °C.
This means that you can start the engine right away.
● Interrupt the attempt at starting after 10 seconds if the engine does not start
right away and wait for about 30 seconds before repeating the attempt.
● It is possible that the fuse on the diesel preglow system is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒ page 211.
● Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel tank
has run completely dry - up to one minute. This is because the fuel system must
first of all be filled while the attempting to start the engine.
Switching off the engine –
The engine can be switched off by turning the ignition key into position 1 ⇒
fig. 99 . WARNING
● Never switch off the engine before the vehicle is stationary - risk of acci-
dent!
● The brake booster only operates when the engine is running. Greater
physical effort for braking is required when engine is switched off. Because if
you do not stop as normal, this can cause an accident and severe injuries. CAUTION
you should not switch the engine off right away at the end of your journey after
the engine has been operated for a lengthy period at high loads but should be al-
lowed it to run at idling speed for about 2
minutes. This prevents any accumula-
tion of heat when the engine is switched off. £100

The function is automatically activated each time the ignition is switched on.
In the start-stop mode, the engine automatically switches to the vehicle's idle
phase, e.g. when stopped at traffic lights.
Information regarding the current state of the
“START-STOP” system is indicated
in the display of the instrument cluster.
Automatic engine shut down (stop phase)
– Stop the vehicle (where necessary, apply the handbrake).
– Take the vehicle out of gear.
– Take your foot off the clutch.

– Push down on the clutch.
Switching the
“START-STOP” system on and off
You can switch the “START STOP” system on/off by pressing the button ⇒ fig. 105.
When start-stop mode is deactivated, the warning light in the button lights up.
If the vehicle is in the stop phase when manually switching off the system, the en-
gine starts immediately.
The “START-STOP” system is very complex. Some of the procedures are hard to
check without servicing. The general conditions for the proper functioning of the
“START-STOP” system are listed in the following overview.

for more than 2
seconds. While pressing the but-
ton, the warning light lights up. At the same time the memory of the system is
erased and the new calibration is started, which is confirmed with an audible sig-
nal and then the warning light goes out.
● If the warning light does not go out after the basic setting, there is a fault in
the system. Have the vehicle inspected by your nearest specialist garage.
Warning light lights up
If the tyre inflation pressure of at least one wheel is insufficiently inflated in com-
parison to the stored basic value, the warning light ⇒ lights up.
Warning light flashes
If the warning light flashes, there is a system fault. Have the vehicle inspected by
your nearest specialist garage. WARNING
● When the warning light lights up, immediately reduce the speed and
avoid sudden steering and brake manoeuvres. Please stop the vehicle without
delay at the nearest possible stop and inspect the tyres and their inflation
pressures.
● The driver is responsible for the correct tyre inflation pressures. For this
reason, the tyre inflation pressures must be checked regularly.
● Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light can be delayed or does not light up at all.
● The tyre pressure monitoring system does not take away the responsibility
from the driver for the correct tyre inflation pressure. Note
The tyre pressure monitoring system:
● does not replace the regular tyre inflation pressure control, because the sys-
tem cannot detect an even pressure loss,
● cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of
sudden tyre damage. In this case carefully bring the vehicle to a standstill without
sudden steering movements and without sharp braking.
● In order to ensure a proper functioning of the tyre inflation pressure-control
system, it is necessary to carry out the basic setting again every 10 000 km or 1x a
year. Diesel particle filter (diesel engine) In the diesel particle filter the resulting soot particles are collected
and burnt during the combustion of diesel fuel. Fig. 141 Vehicle data sticker
Code 7GG , 7MB or 7MG on the vehicle data sticker, see ⇒ fig. 141 , indicates that
your vehicle is equipped with a diesel particle filter. The vehicle data sticker is lo-
cated on the floor of the luggage compartment and is also stated in the Service
schedule.
The diesel particle filter filters the soot particles completely from the exhaust. The
soot is collected in the diesel particle filter and burnt regularly. To assist this pro-
cedure, we recommend not to drive regularly over short distances.
If the diesel particle filter is full or there is a fault, it is indicated by the warning
light
. WARNING
● The diesel particle filter achieves very high temperatures. Therefore do not
park at points where the hot filter comes into direct contact with dry grass or
other combustible materials - risk of fire!
● Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converters, diesel particle filter or heat shields.
When the engine reaches its operating temperature, these substances might
ignite - risk of fire. Note
When using diesel fuel with high sulphur content the life of the diesel particle fil-
ter is clearly reduced. A specialist garage will be able to tell you which countries
use only diesel fuel with high sulphur content. 160

Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
Having your vehicle serviced regularly at a specialist garage enables you to satisfy
one of the requirements for economical motoring even before you set off on your
journey. Keeping your vehicle properly serviced not only has a positive effect on
the safety of your vehicle and maintaining its value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10 % higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refuelling. Oil consumption is dependent to a consid-
erable extent on the load and speed of the engine. Oil consumption could be as
high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine has a higher oil consumption at first, and rea-
ches its lowest level only after a certain running in time. It is therefore not possi-
ble to correctly assess the oil consumption of a new vehicle until after you have
driven about 5 000 km. For the sake of the environment
● You can achieve additional improvements in your fuel economy by using high-
lubricity oils.
● Check the ground below your car at regular intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garage if you find
any stains caused by oil or other fluids on the floor. Avoid driving short distances Short distances result in an above-average high fuel consumption.
Fig. 144 Fuel consumption in litres/100
km at different temperatures
– Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter must first have reached their optimal operat-
ing temperature in order to effectively reduce fuel consumption and pollutant
emissions.
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel immediate-
ly after starting. Fuel consumption drops to 10 litres/100 km after just 1 kilometre.
The engine reaches its operating temperature (outside temperature and engine
dependent) only after about 4 to 10 kilometres and the fuel consumption then
stabilizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The
⇒ fig. 144 shows the different fuel consumptions for the same distance, on the
one hand at +20 °C and on the other hand at -10
°C. Your vehicle has a higher fuel
consumption in winter than in summer.
Checking tyre inflation pressures Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all times. The
rolling resistance will be increased if the tyre filling pressure is too low. This will
not only increase fuel consumption but also tyre wear and the driving behaviour
will worsen.
Always check the inflation pressure of the tyres when cold. £164
Driving and the Environment

Do not drive with winter tyres all year round for this costs about 10 % more fuel.
Winter tyres are also louder.
No unnecessary ballast Transporting ballast costs fuel.
The fact that every kilogram of extra weight increases your fuel consumption
means that it is worth taking a look in the luggage compartment to avoid trans-
porting any unnecessary ballast.
It is particularly in town traffic, when one is accelerating quite often, that the vehi-
cle weight will have a significant effect upon the fuel consumption. A rule of
thumb here is that an increase in weight of 100 kilograms will cause an increase in
fuel consumption of about 1 litre/100 kilometres.
You may frequently also leave a roof rack fitted on just out of convenience, al-
though you no longer need it. The increased aerodynamic drag of your vehicle
causes it to use about 10 % more fuel than normal at a speed of 100 - 120 km/h,
even when you are not carrying a load on the roof.
Saving electricity Generating electricity costs fuel.
– Switch off electrical components as soon as you no longer need them.
When the engine is running, the alternator generates and supplies electrical pow-
er. If more electrical components of the electrical system are switched on, more
fuel is needed to operate the alternator.
Keeping a log of your fuel consumption If you really wish to keep a close check on your
fuel consumption, it is best to en-
ter the figures in a logbook. This does not take much time but is a very worthwhile
exercise. It enables you to detect any change (positive and negative) at an early
stage and to take any appropriate action.
If you find that your fuel consumption is too high, you should reflect on how,
where and in what conditions you have driven the vehicle since you last refuelled. Environmental compatibility Environmental protection has played a major role in the design, selection of mate-
rials and manufacture of your new ŠKODA. Particular emphasis has been paid to a
number of aspects, including:
Design measures
● Joints designed to be easily detached.
● Simplified disassembly due to the modular structure system.
● Improved purity of different classes of materials.
● Identification of all plastic parts in accordance with VDA Recommendation
°260.
● Reduced fuel consumption and exhaust emission CO
2.
● Minimum fuel leakage during accidents.
● Reduced noise.
Choice of materials
● Extensive use of recyclable material.
● Air conditioning filled with CFC-free refrigerant.
● No cadmium.
● No asbestos.
● Reduction in the “vaporisation” of plastics.
Manufacture
● Solvent-free cavity protection.
● Solvent-free protection of the vehicle for transportation from the production
plant to the customer.
● The use of solvent-free adhesives.
● No CFCs used in the production process.
● Without use of mercury.
● Use of water-soluble paints. £ 165

In order to avoid damage to the vehicle when driving through bodies of water (e.g.
flooded roads), observe the following:
●
Determine the depth of the water when driving through bodies of water. The
water can reach at the maximum the web on the lower sill of the vehicle
⇒ fig. 145 .
● 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 induc-
tion 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 per-
mit this. Do not place any other road users in jeopardy. CAUTION
● When driving through bodies of water, parts 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 permissi-
ble water level for your vehicle.
● Potholes, mud or rocks can be hidden under the water making it difficult or im-
possible 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. 167

Towing a trailer
Technical requirements Your vehicle is designed primarily for transporting persons and luggage. It can,
however, also be used for towing a trailer - provided certain technical equipment
is fitted.
If your vehicle has been
factory-fitted with a towing device or has a towing device
from ŠKODA Original Accessories, then the towing device satisfies all technical
and legal requirements.
Your vehicle is fitted with a 13-pin power socket for the electrical connection be-
tween the vehicle and trailer. If the trailer which you wish to tow has a 7-pin con-
nector, you can use a suitable adapter from
ŠKODA Original Accessories.
This work must be carried out in accordance with the manufacturer's specifica-
tions if a towing device is retrofitted.
Authorised ŠKODA Service Partners can provide detailed information about retro-
fitting a towing device and for any necessary modifications to the cooling system. WARNING
We recommend that you have the towing device from ŠKODA Original Acces-
sories installed by an authorised
ŠKODA Service Partner. He is familiar with all
the relevant details relating to retrofitting such equipment. There is a risk of
an accident if the towing device is not properly fitted!
General Maintenance Trailer load
The permissible trailer load must on no account be exceeded.
You can negotiate appropriately steeper inclines and descents if you do not make
full use of the permissible trailer load.
The trailer loads specified only apply for
altitudes up to 1000 metres above mean
sea level. The fact that the engine power output drops with increasing height due
to a lowering of air pressure and thus the ability to climb, means that the towed
weight must be reduced by 10 % for every further increase of 1 000 metres in height above sea level. The towed weight is the weight of the (laden) vehicle and
the (laden) trailer together. One should take this into account before driving up to
higher altitudes.
The trailer and drawbar load information on the type plate of the towing device
are merely test data for the towing device The data relating to your vehicle,
which is often less than this test data, can be found in your vehicle registration
documents.
Distribution of the load
Distribute the load in the trailer in such a way that any heavy items are located as
close as possible to the axle. Secure the items to prevent them slipping.
Tyre pressure
Correct the tyre inflation pressure on your vehicle for that of
“fully laden”
⇒ page 192. The inflation pressure of the tyres fitted to the trailer adjust in ac-
cordance with the manufacturer's recommendation.
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see the
traffic behind the trailer with the standard rear-view mirrors. Both exterior mirrors
should be attached to folding arms. Adjust the mirrors so that they provide you
with an adequate field of view to the rear.
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 49.
Detachable ball head
The ball head is detachable on vehicles with towing device and can be obtained
from ŠKODA Original Accessories. It is stowed together with separate fitting in-
structions in the spare wheel well in the luggage compartment of the vehicle. Note
● We recommend that you also have your vehicle inspected between service in-
tervals if you tow a trailer frequently.
● The handbrake on the towing vehicle must be put on when coupling and de-
coupling the trailer. 168

Driving Tips
–
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
combination.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for coun-
tries 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 conditions, particularly near acci-
dent black spots.
You must always reduce your speed immediately 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 engine speed when the outside temperature
is very high ⇒ page 11, 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 185, Inspecting the coolant level. Please refer to the following guidelines
⇒ page 25, 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 independ-
ent 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 the slope without any drop in
speed. 169

● 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.
● For safety reasons, the bonnet must always be properly closed when driv-
ing. One should therefore check that the lock has in fact engaged properly af-
ter closing the bonnet.
● Stop your vehicle immediately while driving if you notice that the lock is
not properly engaged and close the bonnet properly - risk of an accident! CAUTION
Never open the bonnet using the locking lever - danger of causing damage. 180
