WARNING
● If the brake system warning light  comes on together with the ABS
warning light  stop the vehicle immediately and check the brake fluid level
in the reservoir ⇒ page 156
, Brake fluid. If the fluid level has dropped below
the MIN marking, do not drive any further - risk of accident! Contact a Škoda
dealer to obtain professional assistance.
● Pay attention to the following instructions ⇒
 page 150, Working in the en-
gine compartment before checking the brake fluid level and opening the bon-
net.
● If the brake fluid is at the correct level, the ABS control function has failed.
The rear wheels may then block very rapidly when braking. In certain circum-
stances, this can result in the rear end of the car breaking away - risk of skid-
ding! Drive carefully to the nearest specialist garage and have the fault recti-
fied. 
Brake system The warning light
 lights up when the brake fluid level is too low or there is a
fault in the ABS.
if the warning light flashes  and an audible signal sounds three times,
stop and
check the brake fluid level ⇒  .
The following text will be displayed in the information display: Brake fluid Owner's manual
If there is a fault in the ABS which also influences the function of the brake sys-
tem (e.g. distribution of brake pressure), the ABS warning light  comes on and at
the same time the brake system warning light starts flashing . Be aware that
not only the ABS but also another part of th brake system is defective ⇒  .
An audible signal sounds three times as an additional warning signal.
One should get used to high pedal forces, an extended free play of the brake ped-
al and long braking distances when carefully driving to the specialist garage.
For further information on the brake system ⇒ page 127,

Brakes. WARNING
● Pay attention to the following instructions before checking the brake fluid
level and opening the bonnet ⇒ page 150

, Working in the engine compart-
ment.
● If the brake system warning light  does not go out a few seconds after
switching on the ignition or comes on when driving, stop immediately and
check the brake fluid in the reservoir ⇒

 page 156, Brake fluid. If the fluid level
has dropped below the MIN marking, do not drive any further - risk of acci-
dent! Contact a Škoda dealer to obtain professional assistance. 
Handbrake  The warning light
 comes on if the handbrake is applied. An audible warning is
also given if you drive the vehicle for at least 3 seconds at a speed of more than 6
km/h.

Instruments and warning lights

Pedals
Concerning a secure depressing of the pedal, you should use only footmats from
the ŠKODA Original Accessories.
Operation of the pedals must not be hindered! WARNING
● Greater pedal distances may be needed when there is a fault in the brake
system.
● Do not place any footmats or other additional floor coverings in the area of
the pedals in order to ensure that all the pedals can be fully depressed and are
able to return unobstructed to their initial position - risk of accident!
● There must be no objects on the floor which could roll under the pedals.
You would then no longer be able to apply the brakes, operate the clutch or
accelerator - risk of accident! 
luggage compartment
Loading the luggage compartment Please observe the following in the interest of maintaining good handling charac-
teristics of your vehicle:
– Distribute the items of luggage as evenly as possible.
– Place heavy objects as far forward as possible.
– Attach the items of luggage to the lashing eyes or the fixing net
⇒
 page 56.
In the event of an accident, there is such a high kinetic energy which is produced
by small and light objects that they can cause severe injuries. The magnitude of
the kinetic energy depends on the speed at which the vehicle is travelling and on
the weight of the object. The speed at which the vehicle is travelling is in this case
the more significant factor.
Example: In the event of a frontal collision at a speed of 50 km/h, an unsecured
object with a weight of 4.5 kg produces an energy, which corresponds to 20 times
its own weight. This means that it results in a weight of approx. 90 kg. You can
imagine the injuries that can occur, if this “bullet” is flying through the interior
compartment and hits an occupant. WARNING
● Store the objects in the luggage compartment and attach them to the
lashing eyes.
● Loose objects in the passenger compartment can be thrown forward dur-
ing a sudden manoeuvre or in case of an accident and can injure the occupants
or other oncoming traffic. This risk is still increased, if the objects which are
flying around are hit by a deployed airbag. In this case, the objects which are
thrown back can injure the occupants - hazard.
● Please note that the handling properties of your vehicle may be affected
when transporting heavy objects as a result of the displacement of the centre
of gravity. The speed and style of driving must be adjusted accordingly.
● The items carried in the luggage compartment should be stored in such a
way that no objects are able to slip forward if there are any sudden driving or
braking manoeuvres undertaken - risk of injury!
● When transporting fastened objects which are sharp and dangerous in the
luggage compartment enlarged by folding the rear seats forward or removing
the rear seats, ensure the safety of the passengers transported on the other
rear seats ⇒

 page 103, Correct seated position for the occupants on the rear
seats.
● If the rear seats next to the folded forward seat are occupied, ensure max-
imum safety, e.g. by placing the goods to be transported in such a way that a
folding back of the seat is prevented in case of a rear collision.
● Never drive with the boot lid fully opened or slightly ajar otherwise ex-
haust gases may get into the interior of the vehicle - risk of poisoning!
● On no account exceed the permissible axle loads and the permissible gross
weight of the vehicle - risk of accident!
● Never transport occupants in the luggage compartment. CAUTION
Please ensure that the heating elements of the rear window heater are not dam-
aged as a result of objects sliding in this area. Note
● Tyre pressure must be adjusted to the load ⇒
 fig. 130.
● The circulation of air in the vehicle helps to prevent the windows from misting
up. The used air streams out through the air venting slits which are located under
the bumper in the luggage compartment. Check for yourself that the air venting
slits are not covered.  55

WARNING
● Please do not place anything on top of the dash panel. Such objects might
slide or fall down when driving (when accelerating or cornering) and may dis-
tract you from concentrating on the traffic situation - risk of accident!
● Ensure that when driving no objects from the centre console of from other
storage possibilities may get into the footwell of the driver. You would then
no longer be able to apply the brakes, operate the clutch or accelerator - risk
of accident! 
Storage compartments on the front passenger side Fig. 63 Dash panel: Storage compart-
ments on the front passenger side
On some vehicles, the storage compartments are not equipped with lids.
Opening and closing the storage compartments on the front passenger side
– Pull the handle of the lid in direction of arrow ⇒  fig. 63 and fold it open. –
Swivel the flap until it is heard to lock.
A pin holder is located inside the lower flap. WARNING
The storage compartments must always be closed when driving for safety rea-
sons. 
Cooling of storage compartment on front passenger side Fig. 64 Storage compartment: Using
cooling system
– You can switch the cooling system on or off using the control dial ⇒ fig. 64 .
Opening the air inlet when the air conditioning system is on causes fresh or interi-
or air to flow into the storage compartment.
We recommend that you switch off the cooling if it is operating in the heating
mode or if you are not using the cooling system for the storage compartment.  65

The handbrake warning light
 lights up when the handbrake is applied, provided
the ignition is on.
A warning signal sounds and the following text appears in the Information display
if you have inadvertently driven off with the handbrake applied:
Release parking brake!
The handbrake warning is activated if you drive at a speed of more than 6 km/h
for more than 3 seconds. WARNING
● Please note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating which will
have a negative effect on the operation of the brake system - risk of accident!
In addition this can result in premature wear of the rear brake pads.
● 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! CAUTION
After the car has come to a stop, always first of all apply the handbrake firmly be-
fore then additionally engaging a gear (manual gearbox) or moving the selector
lever into position P (automatic gearbox). 
Parking aid The parking aid provides a warning of obstacles behind the vehicle.
Fig. 81 Parking aid: Range of sensorsThe audible parking aid determines the distance from the rear bumper to an ob-
stacle behind the car with the aid of ultrasound sensors. The sensors are integra-
ted in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle
(area
A ⇒ 
fig. 81 ). The interval between the warning signals becomes shorter as
the clearance is reduced.
A continuous tone sounds from a distance of approx. 30 cm (area B ) - danger
area. You should not reverse any further after this signal sounds! If the vehicle is
equipped with a factory-fitted towing device, the indication threshold of the dan-
ger area starts -

continuous tone - 5 cm further behind the vehicle. The vehicle
can be extended through an installed detachable towing device.
On factory-fitted radio navigation systems and car stereos, the distance to the ob-
struction can also be shown graphically in the display. On vehicles with a factory-
fitted towing device, the rear sensors are deactivated when towing a trailer. The
driver is informed about this by a graphic display (vehicle towing a trailer) in the
radio or the radio navigation display. The factory-fitted radio or navigation system
can be set so that the play function volume decreases when activating the park-
ing aid, see Owner's Manual radio or radio navigation system. As a result, the sig-
nal tones from the parking aid can be better recognised.
Activating
The parking aid is activated automatically when reverse gear is engaged and the
ignition is turned on. This is confirmed by a brief audible signal.
Deactivating
The parking aid is deactivated by disengaging the reverse gear or by switching the
ignition off. £82
Starting-off and Driving

How are seat belts correctly fastened?
Fastening three-point seat belts Fasten your seat belt before starting!
Fig. 94 Routing of belt webbing over the shoulders and the lap belt/Routing of belt webbing
for an expectant mother
–
Correctly adjust the seat and the head restraint before fastening your seat
belt ⇒
 page 102, Correct seated position.
– Slowly pull the belt webbing at the tongue of the lock over your chest and pel-
vis ⇒  .
– Insert the tongue of the lock into the seat belt buckle belonging to the seat
until it is heard to lock in place.
– Pull on the seat belt to check that it has also reliably engaged in the lock.
Each three-point seat belt is equipped with an inertia reel. This inertia reel offers
you complete freedom of movement if the belt is unreeled slowly. If the brakes
are applied suddenly, the inertia reel will block. The belts also block when the car
accelerates, when driving downhill and when cornering.
Expectant mothers must also wear the seat belt ⇒  . WARNING
● The shoulder part of the seat belt must never run across your neck but
must run approximately over the middle of the shoulder and fit snugly against
the chest. The lap part of the belt must run across the hip and must never be
routed across the stomach. It must always fit snugly ⇒

 fig. 94 - left. Adjust the
belt webbing as required.
● The lap part of the belt should be positioned as low as possible at the pel-
vis of an expectant mother in order to avoid exerting any pressure on the low-
er abdomen ⇒ fig. 94 - right.
● Always ensure that the webbing of the seat belts is properly routed. Seat
belts which are not correctly adjusted can themselves cause injuries even in
minor accidents.
● A seat belt which is hanging too loose can result in injuries as your body is
moved forward by the kinetic energy produced in an accident and is then sud-
denly held firm by the belt.
● Only insert the lock tongue into the lock which is the correct one for your
seat. This will affect the protection which the belt offers and increase the risk
of an injury. 
Seat belt height adjuster on the front seats Fig. 95 Front seat: Seat belt height ad-
juster
The seat belt height adjuster makes it possible for you to adapt the routing of the
front three-point seat belt in the area of the shoulder to match your body size.
– To adjust the belt height press the height adjuster and move it up or down
⇒ fig. 95 .
– Then pull firmly on the belt to ensure that the seat belt height adjuster has
correctly locked in place. £ 107

Driving Tips
Intelligent Technology Electronic stability programme (ESP)
General General
The ESP aids you in maintaining control of your vehicle in situations in which the
vehicle is driving at its dynamic limits, such as entering a curve fast. The risk of
skidding is reduced and your car thus offers greater driving stability depending on
the conditions of the road surface. The system operates at all speeds.
The following systems are integrated into the electronic stability programme:
● Electronic Differential Lock (EDL),
● Traction control system (TCS),
● Antilock brake system (ABS),
● Brake Assist,
● Uphill Start Assist.
Operating principle
The ESP switches on automatically when the engine is started and then conducts
a self-test. The ESP control unit processes data from the individual systems. It al-
so processes additional measurement data which are supplied by highly sensitive
sensors: the rotational velocity of the vehicle about its vertical axis, the lateral ac-
celeration of the vehicle, the braking pressure and the steering angle.
The direction which the driver wishes to take is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual be-
haviour of the vehicle. If differences exist, such as the car beginning to skid, the
ESP will automatically brake the appropriate wheel.
The car is stabilised again by the forces which take effect when the wheel is
braked. Intervention into the brake system takes place primarily on the outer front
wheel of a vehicle which tends to oversteer (tendency for the rear of the vehicle
to break away) while occurs this is on the inner rear wheel of a vehicle which
tends to understeer (tendency to shift out of the curve). This braking control cycle
is accompanied by noises. During an intervention of the system, the warning light
 flashes quickly in the
instrument cluster.
The ESP system cannot be switched off, only the TCS system can be switched off
by pressing the button ⇒
 fig. 113. The warning light  ⇒ page 25 lights up if the
TCS system is switched off.
The warning light  lights up permanently if there is a fault in the ESP system.
The fact that the ESP system operates together with the ABS means that the ESP
warning light will also come on if the ABS system is not operating properly.
If the warning light  comes on immediately after starting the engine, the ESP
system can be switched off for technical reasons. In this case, the ESP system can
be switched on again by switching the ignition on and off. If the warning light
goes out, the ESP system is fully functional again. WARNING
It is also not possible for the ESP to overcome the physical limits of the vehi-
cle. Even if a vehicle fitted with ESP you should still always adapt your style of
driving to the condition of the road surface and the traffic situation. This par-
ticularly applies when driving on slippery and wet roads. The increased safety
offered must not tempt you to take greater risks than otherwise - risk of an
accident! Note
● All four wheels must be fitted with the same tyres in order to achieve prob-
lem-free operation of the ESP. Differing rolling circumferences of the tyres can
lead to an undesirable reduction in the engine output.
● Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the ESP ⇒

Electronic Differential Lock (EDL)
The electronic differential lock prevents an individual wheel from
slipping.
Models fitted with ESP are equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to start off, acceler-
ate and climb a steep hill when the conditions of the road surface are unfavoura-
ble.
Operating principle
The EDL is activated automatically, that is without any action on the part of the
driver. It monitors the speeds of the driven wheels with the aid of the ABS sen-
sors. Should only one drive wheel begin spinning on a slippery surface there will
be an appreciable difference in the speed of the driven wheels. The EDL function
brakes the slipping wheel and the differential transmits a greater driving force to
the other driven wheel. This control process is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unusually severe stresses exist in order to
avoid excessive heat generation in the disc brake on the wheel which is being
braked. The vehicle can continue to be driven and has the same characteristics as
a vehicle not fitted with EDL.
The EDL switches on again automatically as soon as the brake has cooled down. WARNING
● Carefully depress the accelerator when accelerating on uniformly slippery
road surfaces, such as ice and snow. The driven wheels might still spin despite
the EDL and affect the stability of the vehicle - risk of an accident!
● You should always adapt your style of driving to the condition of road sur-
face and to the traffic situation even when your vehicle is fitted with EDL. The
increased safety offered must not tempt you to take greater risks than other-
wise - risk of an accident! Note
● If the ABS or ASR or, where applicable, ESP indicator light lights up, the EDl
may have a fault. Have the vehicle inspected by your specialist garage as soon as
you can.
● Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the EDL ⇒

Traction control system (TCS) The traction control system prevents the driven wheels from spin-
ning when accelerating.
Fig. 113 TCS switch
General
The TCS makes it much easier, and sometimes at all possible, to start off, acceler-
ate and climb a steep hill when the conditions of the road surface are unfavoura-
ble.
Operating principle
The TCS switches on automatically when the engine is started and then conducts
a self-test. The system monitors the speeds of the driven wheels with the aid of
the ABS sensors. If the wheels are spinning, the force transmitted to the road sur-
face is automatically adapted by reducing the engine speed. The system operates
at all speeds.
The TCS operates in combination with the ABS ⇒ page 128, Antilock brake system
(ABS)

. The TCS will not function if a fault exists in the ABS system.
