Towing a trailer
208
Towing a trailerTo w i n g a t r a i l e rTechnical requirements The towing device must satisfy
certain technical requirements.
Your vehicle is designed primarily for tr
ansporting persons and luggage. It can,
however, also be used for towing a traile
r - provided certain te
chnical equipment is
fitted. If your vehicle has already been supplied with a
factory-fitted
towing device then
everything that is necessary
for towing a trailer in technical terms, and in terms of
the law, has already been taken into account. Your vehicle is fitted with a 13-pin po
wer socket for the electrical connection
between the vehicle and trailer. If th
e trailer which you wish to tow has a
7-pin
connector
, you can use a suitable adapter
18) from Škoda original accessories.
This work must be carried out in accordan
ce with the manufacturer's specifications
if a towing device is retrofitted. Authorised Škoda Service Partners are familiar with details relating to retrofitting 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 There are a number of points to
pay attention to when towing a
trailer.Trailer load The permissible trailer load must
on no account be exceeded.
You can negotiate appropriatel
y steeper inclines and desc
ents if you do not make
full use of the perm
issible trailer load.
The trailer loads specified only apply for
altitudes
up to 1 000 metres above mean
sea level. The fact that the engine power ou
tput drops with increasing height due to
a lowering of air pressure and thus the abil
ity 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 alti- tudes. The trailer and drawbar load information on the type plate of the towing device are merely test data for the tow
ing 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 inflation pressure Select the tyre inflation pressure on your vehicle for that of “fully laden”, ⇒ page 238. The inflation pressure of the tyres fitted to the trailer adjust in accord- ance 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

supplied with the towing device.

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 th
e aid of the headlight beam adjuster
⇒ page 63. Detachable ball head The ball rod is detachable on vehicles which feature a factory-fitted towing device. It is stowed together with separate fitting instructions in the spare wheel well in the luggage compartment of the vehicle. Further information on the towing device
⇒page 210.
Note
•
We recommend that you also have yo
ur vehicle inspected between service
intervals if you tow a trailer frequently.•
The handbrake on the towing vehicle
must be put on when coupling and
decoupling 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 temper
ature gauge if the outside temper-
ature 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, particul
arly near accident
black spots. You must always reduce your speed immedi
ately 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 down-
hill 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 18, “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 yo
ur speed immediately. Stop and switch off
the engine if the warning light
 in the instrument cluste
r begins flashing. Wait a
few minutes and check the level of coolant in the coolant expansion bottle ⇒ page 229, “Inspecting the coolant level”. Please refer to the following guidelines
⇒page 36, “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

WARNING
•
Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi
ng! Wait long enough until the steam
or coolant has stopped escaping.•
For safety reasons, the bonnet must always be properly closed when
driving. One should therefore check that
the lock has in fact engaged prop-
erly after closing the bonnet.•
Stop your vehicle immediately while driv
ing if you notice that the lock is
not properly engaged and close the bonne

Caution
Never open the bonnet using the locking lever - danger of causing damage.Working in the engine compartment Particular care is required when carrying out any work in the engine compartment!There is a risk of injuries, scalding,
accidents and fire when working in the
engine 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 compart-
ment of your car is a hazardous area

If your vehicle is fitted with a ma
nual gearbox, move the gearshift lever
into Neutral, or if it is fitted with
automatic gearbox, move the selector lever
into position P.•
Allow the engine to cool down.
•
Keep children clear of the engine compartment.
•
Never spill oil and other fluids over the hot engine. Such fluids (e.g. the
antifreeze 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 expa
nsion bottle as long
as the engine
is still warm. The cooling system is pressurized!•
Cover over the cap of the coolant expansion 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 cleani
ng cloth or tools lie in the engine
compartment.•
If you wish to work under the vehicle, you must secure the vehicle from
rolling away and support it with suitab

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

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.

spare wheel
which differs from the tyres fitted to the vehicle (e.g. winter tyres
or low-profile tyres) should only be used for a short time in the event of a puncture and when adopting an appropriately cautious
style of driving. It should be replaced
as quickly as possible by a normal wheel.
WARNING
•
Only use those tyres or wheel rims which have been approved for your
model of Škoda Auto vehicle. Failure to observe this instruction will adversely affect the road safety of your vehicle - risk of accident! Approval and licencing of your vehicle on publ
ic roads may also become void as a
result.•
You must on no account drive at a hi
gher 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
cases and when adopting an appropriately cautious style of driving.•
Never fit tyres which have already be
en 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 cases and only then when adopting an appropriately cautious style of driving.•
Do not, where possible, replace indivi
dual tyres but at least replace them
on both wheels of a given axle at the sa
me 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 boltsWheels 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 essent
ial 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 adequate
flow of air remains assured for cooling the brake system. The 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 th
e wheel bolts, the
wheel can loosen
when the car is moving - risk of accident!
