ing from natural gas to petrol operation takes place in the following situations
(examples). ▶ With an empty gas tank or not enough pressure in the tank.
▶ After refuelling with natural gas.
▶ At very low surrounding temperatures.
To ensure the correct functioning of the fuel system, every 6 months the fuel tank for petrol should be run down until the warning light  comes on.
Gas leak
If a gas leak is suspected (noticeable odour), proceed as follows. ▶ Stop the vehicle.
▶ Switch off the ignition.
▶ Extinguish cigarettes, switch off spark-producing or incendiary items and re-
move them from the vehicle.
▶ Open the doors and the boot lid to ventilate the vehicle sufficiently.
▶ Do not continue to drive if the odour persists.
▶ If it is not possible to leave an enclosed area with a vehicle with a gas leak
(e.g. in a tunnel, underpass, garage, ferry, etc.), call the emergency services
immediately.
Seek help from a specialist garage to correct the gas system fault.
In a traffic accident
If a gas leak is suspected in a traffic accident, proceed as follows.
▶ Switch off the ignition.
▶ Extinguish cigarettes, switch off spark-producing or incendiary items and re-
move them from the vehicle.

Vehicle battery: Open the cover / acid level indicator
Read and observe
and on page 258 first.
The battery condition is checked regularly by a specialist garage as part of the
inspection service.
Check the acid level
For car batteries with acid level indicator, acidity can be checked on the basis
of a colour display. In vehicle batteries with the label “AGM” there is no acid
level examination.
Depending on the equipment, the vehicle battery may be provided with a cov-
er, this can be opened in the direction of arrow » Fig. 296 -
 .
Air bubbles can influence the colour of the indicator. For this reason carefully
tap on the indicator before carrying out the check » Fig. 296 -
 .
Black colour – electrolyte level is correct.
Colourless or light yellow colour – electrolyte level too low, the battery must be replaced.
Battery discharge
If frequent short journeys are made, the vehicle battery does not recharge suf- ficiently.
The battery capacity decreases at low temperatures.
If the vehicle is not used for longer than 3 to 4 weeks, then disconnect the
negative terminal 
of the battery or charge the battery constantly with a very
low charging current.
Charging

Advice on tyre/wheel usage
During the first 500 km, new tyres do not offer optimum grip; appropriate care
should therefore be taken when driving.
Tyres with the deeper profiles should always be fitted to the front wheels.
Rims and wheel bolts are matched to each other in terms of design. We rec-
ommend that you use rims and wheel bolts from ŠKODA Original Accessories.
Wheels and tyres should always be stored in a cool, dry and dark place. The
tyres themselves should be stored vertically.
Tyre life
Tyres age losing their original characteristics, even if they are not used. We
recommend that you do not use tyres that are more than 6 years old.
The manufacturing date is indicated on the tyre sidewall (possibly on the in-
side ). For example, DOT ... 10 16... means, for example, that the tyre was manu-
factured in the 10. week of 2016.
Tyre damage
We recommend checking your tyres and wheel rims for damage (punctures,
cuts, splits and bulges etc.) on a regular basis.
Remove any foreign objects in the tyre’s profile immediately (e.g. small stones).
Foreign bodies which have penetrated into the tyre (e.g. screws or nails)
should not be removed and help should be sought from a specialist garage. 
260General Maintenance

WARNING■Never clamp the jump cable to the negative terminal of the discharged
battery - There is a risk of explosion.■
The non-insulated parts of the terminal clamps must never touch each
other – risk of short circuit!
■
The jump-start cable connected to the positive terminal of the battery
must not come into contact with electrically conducting parts of the vehicle
– risk of short circuit!
■
Position the jump cables so that they cannot be caught in rotating parts
in the engine compartment - danger of injuries and the risk of vehicle dam-
age.
Towing the vehicle
Information about the towing process
Fig. 311
Braided tow ropes/spiral tow rope
To tow with a tow rope, only use a braided synthetic fibre rope » Fig. 311 -
 »
.
Attach the tow rope or the tow bar to the towing eyes at the front
» page 274 ,towing eyes at the rear » page 274or to thetowing device of the
trailer device » page 230 .
Conditions for towing. Cars with automatic gearboxes must not be towed with the rear wheels
raised - there is a risk of gearbox damage!
If the gearbox has no oil, your vehicle must be towed with the front axle
raised clear of the ground or on a breakdown vehicle or trailer.
The maximum towing speed is 50 km/h.
The vehicle must be transported on a special breakdown vehicle or trailer
if it is not possible to tow in the vehicle in the way described or if the tow-
ing distance is greater than 50 km.
Driver of the tow vehicle›
On vehicles with manual transmission , engage gear slowly when starting.
›
On vehicles with automatic transmission , accelerate with particular care.
›
Only then approach correctly when the rope is taut.
Driver of the towed vehicle
›
If possible, the vehicle should be towed with the engine running. The brake
booster and power steering only operate if the engine is running, otherwise
much greater force has to be applied to the brake pedal and more power has
to be expended for steering.
›
If it is not possible to start the engine, switch on the ignition so that the
steering wheel does not lock and so that the turn signal lights, windscreen
wipers and windscreen washer system can be used.
›
Take the vehicle out of gear or move the selector lever into position N if the
vehicle is fitted with an automatic gearbox.
›
Keep the tow rope taut at all times during the towing procedure.
WARNING■ Spiral tow ropes must not be used for towing » Fig. 311-  , the towing
eye may unscrew out of the vehicle - There is a risk of an accident.■
The tow rope should not be twisted - risk of accident.
CAUTION
■ Do not tow-start the engine – There is a risk of damaging the engine. The
battery from another vehicle can be used as a jump-start aid » page 272, Jump-
starting .■
For off-road towing manoeuvres, there is a risk to both vehicles that the fas-
teners may become overloaded and damaged.
Note
We recommend that you use a tow rope from ŠKODA Original Accessories.273Emergency equipment, and self-help

We recommend having bulbs replaced by a specialist garage or seeking other
expert help in the event of any uncertainties.
▶ Switch off the ignition and all of the lights before replacing a bulb.
▶ Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
We recommend having the headlight settings checked by a specialist garage after replacing a bulb in the low, high or fog beam.
In the case of failure of a Xenon gas discharge bulb or an LED diode, visit a
specialist garage.WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 252.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty by other road users.
■
Bulbs H7 H8 and H15 are pressurised and may burst when changing the
bulb - risk of injury! We therefore recommended wearing gloves and safety
glasses when changing a bulb.
■
Do not carry out any work on the Xenon gas discharge lamps - risk of
death!
CAUTION
Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth,
napkin, or similar.
Note
■ This Owner's Manual only describes the replacement of bulbs where it is pos-
sible to replace the bulbs on your own without any complications arising. Other
bulbs must be replaced by a specialist garage.■
We recommend that a box of replacement bulbs always be carried in the ve-
hicle.
