Monitoring the airbag system
The warning light  comes on for a few seconds when the ignition is switched
on.
There is a fault in the system if the warning light does not go out or flashes while
driving » . This also applies if the warning light does not come on when the ig-
nition is switched on.
The functionality of the airbag system is also monitored electronically when one
airbag has been switched off.
The following situation applies if the front or side airbag or belt tensioner have
been switched off using the vehicle system tester:
› The warning light
 lights up for around 4
seconds after switching on the igni-
tion and then flashes approximately another 12 seconds in 2 second intervals.
The following situation applies if the airbag has been switched off using the
key switch for the airbag in the front passenger storage compartment:
› The warning light
 comes on for a few seconds when the ignition is switched
on;

WARNING (Continued)
■ If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must be
ensured that the air supply to the front wheel brakes is not reduced. Other-
wise, the functionality of the brake system could be impaired – risk of acci-
dent!
■ Please note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating, which can
have a negative effect on the operation of the brake system – risk of accident!
■ Never leave children unattended in the vehicle. The children might, for ex-
ample, release the handbrake or take the vehicle out of gear. The vehicle
might then move off – risk of accident!
■ A lack of fuel can cause irregular engine running or cause the engine to shut
down. The brake assist systems would then be without function – risk of acci-
dent!
■ Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions. The increased safety offered by the brake assist systems
must not tempt you to take greater risks than otherwise – risk of an accident! ■ The normal braking system is still fully functional if there is an ABS fault.
Visit a ŠKODA specialist garage immediately and adjust your style of driving
according to the damage to the ABS as you will not know how great the dam-
age is and the limitation it is placing on the braking efficiency. CAUTION
■ Observe the recommendations on the new brake pads » page 91.
■ Never let the brakes slip with light pressure on the pedal if braking is not neces-
sary. This causes the brakes to overheat and can also result in a longer braking
distance and excessive wear. ■ All four wheels must be fitted with the same tyres approved by the manufactur-
er to ensure the brake assist systems operate correctly. Note
■ If the brakes are applied in full and the control unit for the braking system con-
siders the situation to be dangerous for the following traffic, the brake light
flashes automatically. After the speed was reduced below around 10

km/h or the
vehicle was stopped, the brake light stops flashing and the hazard warning light
system switches on. The hazard warning light system is switched off automatical-
ly after accelerating or driving off again. ■ Before negotiating a steep downhill section, reduce the speed, shift down into
the next lower gear (manual gearbox) or select a lower drive position (automatic
gearbox). As a result, the braking effect of the engine will be used, reducing the
load on the brakes. Any additional braking should be completed intermittently,
not continuously. ■ Changes to the vehicle (e.g. to the engine, brakes, chassis or another combina-
tion of tyres and wheels) can influence the functionality of the brake assist sys-
tems »

page 125, Accessories, changes and replacement of parts .
■ If a fault occurs in the ABS system, the ESC, TCS and EDL also do not work. A
warning light  » page 17 comes on if a fault occurs in the ABS system. Ð Information for braking
First read and observe the introductory information and safety warn-
ings on page 58.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driving
style. The brake pads wear more quickly if a lot of journeys are completed in
towns and over short distances or if a very sporty style of driving is adopted. If
operated under severe conditions, the thickness of the brake pads must be
checked by a ŠKODA specialist garage before the next service appointment.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake pads
may be moist or have a coating of ice or layer of salt on them in winter. The
brakes are cleaned and dried by applying the brakes several times.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking
system. If the brake system is not used much or if there is corrosion on the sur-
face, we recommend cleaning the brake discs by firmly applying the brakes from a
high speed. £

Starting-off and Driving

WARNING
■ The brake servo unit and power steering only operate if the engine is run-
ning.
■ Never let the vehicle roll with the engine switched off. CAUTION
If the START-STOP system is used at very high outside temperatures over a very
long period of time, the vehicle battery can be damaged. Note
■ Changes to the outdoor temperature can have an effect on the internal temper-
ature of the vehicle battery even after several hours. If the vehicle remains out-
doors for a long time in minus temperatures or in direct sunlight, it can take sev-
eral hours until the internal temperature of the vehicle battery reaches a suitable
temperature for proper operation of the
START STOP system.
■ In some instances it may be necessary to start the engine manually with the ig-
nition key (e.g. when the seat belt is not inserted or the driver's door is opened in
Stop mode for more than approx. 30 seconds). ÐCity Safe Drive

Introduction Fig. 70
Laser sensor/detection range This chapter contains information on the following subjects:
Switching the

City Safe Drive on and off 67
Laser sensor 68
Special driving situations 68
The City Safe Drive system uses the laser sensor » Fig. 70 –  to take readings
about the traffic situation in front of the vehicle at a range of around 10 metres (11
yards) » Fig. 70 –  in a vehicle speed range of 5 - -30

km/h (3 - -19 mph).
If the driver does not respond to an imminent collision, the City Safe Drive system
can automatically apply the brakes to the vehicle to prevent a possible collision.
If the City Safe Drive system is currently slowing the vehicle down automatically,
the warning light will flash  quickly .
Automatic braking interventions can be terminated by pressing the clutch, accel-
erator or by moving the steering wheel.
If the City Safe Drive system is not currently available, or if there is a system fault,
the warning light will flash  slowly .
The following conditions cause the City Safe Drive system to become not availa-
ble.
› Taking bends tightly.
› When fully pressing down the accelerator pedal.
› When the City Safe Drive system function is switched off/faulty.
› When the laser sensor is dirty, concealed or has overheated.
» page 68
› In the event of snow, heavy rain or fog.
› When vehicles are travelling side by side.
› When vehicles are crossing.
› When vehicles are approaching in the same lane.
› When the vehicles are very dirty and have a low level of reflection.
› With high levels of dust. WARNING
■ The
City Safe Drive system cannot exceed physical and system-defined lim-
its. The added convenience of the City Safe Drive system must never give you
a reason to takes risks with regard safety. The driver is always the one re-
sponsible for braking in time.
■ The City Safe Drive system cannot prevent accidents and injuries by itself. £

Introduction
This chapter contains information on the following subjects:
Introductory information 69
Starting-off and driving 69
Selector lever positions 70
Manual gearshift (Tiptronic) 70
Kickdown function 71
Dynamic shift programme 71
Operational faults 71
WARNING
■ Do not depress the accelerator if changing the position of the selector lever
when the vehicle is stationary and the engine is running – risk of accident!
■ Never move the selector lever into position R or when driving - risk of an ac-
cident!
■ When the engine is running and the vehicle is stationary, it is necessary to
hold the car with the brake pedal in all the positions of the selector lever (ex-
cept P and N) since the power transmission is never completely interrupted,
also not when the engine is idling – the vehicle creeps.
■ The selector lever must be placed into position N and the handbrake firmly
applied before the bonnet can be opened and work on the running engine can
be completed - risk of accident! The safety guidelines must always be ob-
served » page 108 , Engine compartment .
■ If stopping on a hill (downhill gradient), never try to maintain the vehicle sta-
tionary with the gear engaged by means of the
“accelerator pedal”, i.e. by let-
ting the clutch slip. This can lead to overheating of the clutch, and subse-
quently to the clutch burning out. The vehicle can roll backward - risk of acci-
dent!
■ If you have to stop on a slope, depress and hold the brake pedal to prevent
the vehicle from rolling back.
■ On a smooth or slippery road surface using the kickdown function can cause
the driven wheels to spin – risk of skidding!
■ Always firmly apply the handbrake before leaving the vehicle! Ð Introductory information
First read and observe the introductory information and safety warn-
ings on page 69.
Shifting up and down through the gears is performed automatically. However, the
gearbox can also be switched into Tiptronic mode M. This mode makes it possible
for you to also shift gears manually » page 70.
The engine can only be left on in position N, when the brake pedal is depressed

.
When parking on a level road surface, it suffices to engage selector lever position
N. When parking on a slope, the handbrake should be applied firmly before the
park position N is selected.
If the selector lever position N is accidentally selected while driving, it is first nec-
essary to release pressure on the accelerator pedal and wait for the idling speed
of the engine to be reached before the selector lever can be engaged in the drive
position. Note
If the N symbol flashes next to the selector lever, engage the selector lever posi-
tion N. Ð Starting-off and driving
First read and observe the introductory information and safety warn-
ings on page 69.
Starting off
›
Firmly depress and hold the brake pedal.
› Press the selector lever towards the left in the spring-tensioned position in the
direction of the arrow » Fig. 74 on page 70 and insert into position D.
› Release the brake pedal and accelerate.
Stop
› The selector lever position
N does not have to be selected when stopping for a
short time, such as at a cross roads. It is sufficient to hold the vehicle stationary
using the foot brake. The engine can, however, be allowed just to idle.
Parking
› Depress the brake pedal.
› Firmly apply the handbrake.

The fuel tank is full when the compressor of the refuelling system automatically
switches off. To stop the refuelling operation prematurely, press the
“Stop ” but-
ton of the refuelling system.
Closing the filler cap
› Check that the sealing ring 3
» Fig. 96
has remained in the gas filler tube. If it
has slipped onto the filling coupling, reinsert it into the gas filler tube.
› Plug the cap 1
onto the gas filler tube.
› Close the filler cap.
In the following situation, it is possible that the tank cannot be fully filled with
natural gas.
› At very high ambient temperatures. The natural gas refuelling systems have
overheating protection. When the ambient temperature reaches a predefined
value, the refuelling system automatically switches off.
› If the refuelling system has been in operation for a longer period, the filling
pressure of the natural gas refuelling system slightly drops. WARNING
■ Stop the engine before refuelling.
■ Always switch off your mobile phone, do not smoke and do not use open
flames when refuelling with natural gas – risk of explosion!
■ When refuelling, never get into the vehicle. If you have to get into your vehi-
cle in exceptional cases, close the door and touch a metal surface before you
touch the filling coupling again. This will avoid electrostatic discharges, which
may generate sparks. Sparks can cause a fire during refuelling. ■ Natural gas is highly explosive and flammable. Incorrect refuelling or improp-
er handling of natural gas can cause a fire, an explosion and injuries. Note
■ The natural gas system of your vehicle is suitable both for fuelling from small
compressors (slow fuelling) and for fuelling from natural gas stations with large
compressors (quick fuelling). ■ Noises that occur during refuelling represent no risk.
■ If the vehicle is parked for a longer period of time immediately after refuelling,
the situation may arise in which the pointer of the fuel tank gauge does not indi-
cate exactly the same level as was the case immediately after refuelling when the
engine is restarted. This is not due to any system leakages but a drop in pressure
in the natural gas fuel tank due to technical reasons after a cooling phase directly
after refuelling. ■
For frequent short-haul traffic, especially at low outside temperatures, the vehi-
cle is driven more frequently in petrol mode than in natural gas mode. This is why
the petrol tank runs empty faster than the natural gas tank.
■ The capacity of the natural gas tank is about 11 kg, of which about 1.5
kg are a
reserve.
■ The capacity of the petrol tank is about 10 l, of which about 5 l
are a reserve.Ð Automatically switching over from CNG mode to petrol mode
First read and observe the introductory information and safety warn-
ings on page 106.
The vehicle automatically switches over from CNG mode to petrol mode when the
following conditions are met:
› when starting the engine, if the coolant temperature is below 15 °C,
› when the natural gas tank is empty,
› after refuelling with natural gas. Ð Natural gas as fuel
First read and observe the introductory information and safety warn-
ings on page 106.
Natural gas is an alternative fuel for motor vehicles. Its main component is meth-
ane (CH 4). The rest is carbon dioxide and lower hydrocarbons.
The strict legal requirements for exhaust emissions of motor vehicles are decisive
for the current significance of natural gas. In direct comparison to all other fossil
fuels, natural gas is one of the fuels which cause the lowest emissions.
Natural gas is odourless and lighter than air. For safety reasons, it is saturated
with odorous substances, so that is perceived even in very small amounts. Ð

Inspecting and replenishing

Loss of coolant
A loss of coolant is first and foremost an
indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a
ŠKODA spe-
cialist garage immediately. CAUTION
If a fault causes the engine to overheat, we recommend visiting a ŠKODA Service
Partner immediately, otherwise serious engine damage may occur. ÐReplenishing the coolant
First read and observe the introductory information and safety warn-
ings on page 108.
›
Switch off the engine.
› Allow the engine to cool.
› Place a cloth over the cap of the coolant expansion reservoir
» Fig. 101 on
page 112 and unscrew the cap carefully.
› Replenish the coolant.
› Turn the cap until it clicks into place.
Do not use an alternative additive if the specified coolant is not available in an
emergency. In this case, just use water and have the correct mixing ratio of water
and the coolant additive restored by a ŠKODA

specialist garage as soon as possi-
ble.
Only use new coolant to top up the system.
Do not fill the coolant above the mark “MAX” » Fig. 101 on page 112! Excess cool-
ant heats up and then is forced out of the cooling system through the pressure
relief valve in the cap. WARNING
■ 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 health.
Therefore always safely store the coolant additive in its original container out
of the reach of children – risk of poisoning!
■ If any coolant splashes into your eyes, immediately rinse out your eyes 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.
ä CAUTION
Do not continue your journey, if it is not possible  to top up the coolant under
the prevailing conditions . Contact a

ŠKODA Service Partner to avoid the risk of
serious engine. Ð Radiator fan
First read and observe the introductory information and safety warn-
ings on page 108.
The radiator fan is driven by an electric motor and controlled according to the
coolant temperature.
After switching off the ignition, the radiator fan can intermittently continue to op-
erate for approx. 10 minutes.
Ð Checking the brake fluid
Fig. 102
Engine compartment: Brake fluid
reservoir
First read and observe the introductory information and safety warn-
ings on page 108.
The brake fluid reservoir is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 110.
› Check the level of brake fluid in the reservoir
» Fig. 102. The level must be be-
tween the
“MIN” and “MAX” markings.
When driving, a slight drop in the fluid level is caused by the wear-and-tear and
automatic adjustment of the brake pads, and is therefore perfectly normal. £

of the air compressor
firmly onto the tyre valve.
› Check that the air release valve 7
is closed.
› Start the engine and run it in idle.
› Plug the connector 9
into 12 Volt socket »

page 46, 12-volt power socket.
› Switch on the air compressor with the ON and OFF switch 8
.
› Allow the air compressor to run until a pressure of 2.0 - 2.5 bar is achieved.
Maximum run time of 8 minutes » !
› Switch off the air compressor.
› If you cannot reach an air pressure of 2.0 – 2.5 bar, unscrew the tyre inflation
hose 5
from the tyre valve.
› Drive the vehicle 10 metres forwards or backwards to allow the sealing agent to
“distribute” in the tyre.
› Firmly screw the tyre inflation hose 5
back onto the tyre valve and repeat the
inflation process.
› If you cannot reach the required tyre inflation pressure here either, this means
the tyre has sustained too much damage. You cannot seal with tyre with the
breakdown kit » .
› Switch off the air compressor.
› Remove the tyre inflation hose 5
from the tyre valve.
Once a tyre inflation pressure of 2.0

– 2.5 bar is achieved, continue the journey at
a maximum speed of 80 km/h (50 mph).
Check the tyre inflation pressure after driving for 10 minutes » page 134.WARNING
■ During inflation, the tyre inflation hose and air compressor may get hot- risk
of injury!
■ Do not place the hot tyre inflation hose or hot air compressor on flammable
materials – risk of fire! ■ If you cannot inflate the tyre to at least 2.0 bar, this means the damage sus-
tained was too serious. The sealing agent cannot be used to seal the tyre. 
Do not drive the vehicle. Get professional assistance! CAUTION
Switch off the air compressor after running 8 minutes at the latest – danger of
overheating! Allow the air compressor to cool a few minutes before switching it
on again. Ð Check after driving for 10 minutes
First read and observe the introductory information and safety warn-
ings on page 132.
Check the tyre inflation pressure after driving for 10 minutes!
If the tyre inflation pressure is 1.3 bar or less:
›
 Do not drive the vehicle!
You cannot properly seal with tyre with the break-
down kit.
› Get professional assistance.
If the tyre inflation pressure is 1.3 bar or more:
› Adjust the tyre inflation pressure to the correct value (see inside of fuel filler
cap).
› Continue driving carefully to the nearest ŠKODA specialist garage at a maxi-
mum speed of 80 km/h (50
mph). Ð Jump-starting

Introduction
This chapter contains information on the following subjects:
Jump-starting 135
Jump-starting in vehicles with the START-STOP system 136
The battery of another vehicle can be used to jump-start your vehicle if the en-
gine will not start because the battery is flat. Jump-start cables are required 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 significantly less than the capacity of the dis-
charged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and in-
sulated terminal clamps. Observe the manufacturer's instructions.
Positive cable – colour coding in the majority of cases is red.
Negative cable – colour coding in the majority of cases is black. £
