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 59, “Headlamp 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 instructions in the spare wheel well in the
luggage compartment of the vehicle.
Further information on the towing device ⇒page 196.
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 temperature 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, particularly 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 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 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 214, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 31, “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

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 212. 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 ⇒page 35, “Engine oil
level* ” whether the oil level is too low. In this case, check the oil level as soon as
possible. Top up with an a ppropriate quantity of oil.
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 of the engine and contact and
obtain professional assistance from a specialist garage.
Replenishing engine oil
– Inspecting the engine oil level ⇒page 211.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 210.
– Inspect the oil level ⇒page 211, “Check engine oil level”.
– 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 209, “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 211. Oil will other-
wise be drawn in through the crankcase ventilation and may pass through the
exhaust system to atmosphere. The oil ma y combust in the catalytic converter and
damage it.
Changing engine oil
The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator ⇒page 12, “Service Interval Display”.
WARNING
•Only carry out the engine oil change, if you have the required profes-
sional knowledge!

Inspecting the coolant level
The coolant expansion bottle is loca ted in the engine compartment on
the right.
– Switch the engine off.
– Open the bonnet ⇒page 209, “Working in the engine compartment”.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 189 .
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 31. We nevertheless recommend inspecting
the coolant level directly at th e 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 209, “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 ⇒fig. 189 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 213, “Coolant”. 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 adjustment 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.

Disconnecting and reconnecting the battery
On disconnecting and reconnecting the battery the following functions are initially
deactivated or are no longer able to operate fault-free.
We recommend having the vehicle checked by a Škoda Service Partner to ensure
full functionality of all electrical systems.
Replacing the battery
You should only replace a battery with a new battery of the same capacity, voltage
(12 V), amperage and of the same size. Škoda Service Partners have a range of suit-
able batteries available.
We recommend that you only have an old battery disposed of by your Škoda dealer
since it does require special disposal.
For the sake of the environment
Batteries contain poisonous substances such as sulphuric acid and lead. They must
be disposed of in accordance with local environmental protection regulations and
on no account as domestic waste.
Windshield washer system
The windshield washer reserv oir contains the cleaning fluid for the windscreen or
rear window and for the headlamp cleaning system*. The reservoir is located at the
front right of the engine compartment ⇒fig. 194 .
The filling level of the container is 3 litres, 5.5 li tres on vehicles which also have a
headlight washing system.
Clear water is not sufficient to intensivel y clean the windscreen and headlights. We
therefore recommend using clean washing water together with the screen cleaner
from Škoda genuine accessorie s (in winter additionally with antifreeze) which is
capable of removing stubborn dirt. Follow the instructions for use on the packaging
when using screen cleaning products.
You should always add antifreeze to the cleaning water in winter even if your
vehicle is fitted with heated windscreen washer nozzles*.
It is also possible in exceptional cases to use methylated spirits when no screen
cleaner with antifreeze is available. The concentration of methylated spirits must
not be more than 15 %. Please note, however, that the antifreeze protection at this
concentration is only adequate down to -5°C.
WARNING
Read and observe the warning notes ⇒page 209, “Working in the engine
compartment” before working in the engine compartment.

tightened up too much.
Note
The set of safety wheel bolts can be obtained from a Škoda Service Partner.
Jump-starting
Initial steps
You can use the battery of another vehicl e for jump-starting yours if the engine
does not start because the battery on your vehicle is flat. You will require jump-start
cables for this purpose.
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the battery
supplying the power must not be significa ntly less than the capacity of the
discharged battery in your vehicle. Jump-start cables
Only use jump-start cables which have an
adequately large cross-section and insu-
lated terminal clamps. Please pay attent ion to the manufacturer's instructions.
Positive cable - colour coding in the majority of cases red.
Negative cable - colour coding in the majority of cases black.
WARNING
•A discharged battery may already freeze at temperatures just below 0°C.
In case of frozen battery carry out no jump-starting - risk of explosion!
•Please pay attention to the warning instructions relating to working in
the engine compartment ⇒page 209, “Working in the engine compart-
ment”.
Note
•There must not be any contact between the two vehicles otherwise current may
flow as soon as the negative terminals are connected.
•The discharged battery must be properly connected to the system of the
vehicle.
•Switch off any mobile phone, pay attent ion to the instructions for use of the
mobile phone in such a situation.
•We recommend purchasing jump-start cabl es from Škoda Service Partners as a
Škoda original accessory or from retailers who sell branded batteries.
