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

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 ⇒

cessories, changes and replacement of parts.  125

During an intervention of the system, the TCS warning light flashes
 in the in-
strument cluster ⇒ page 25.
Switching off
You can switch the TCS off and on again as you wish by pressing the button
⇒ fig. 113. The TCS warning light lights up in the instrument cluster when the TCS
is switched off  ⇒
 page 24.
The TCS should normally always be switched on. It may be good practice in certain
exceptional cases, such as when you wish to have wheel slip, to switch off the
system.
Examples:
● when driving with snow chains;
● when driving in deep snow or on a loose surface;

then you should switch on the TCS again. WARNING
You should always adjust your style of driving to the conditions of the road
surface and the traffic situation. 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 TCS. 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 TCS ⇒

Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions
of the vehicle and your style of driving. Particularly if you drive a great deal in
towns and over short distances or if you adopt a sporty style of driving, it may be
necessary to have the thickness of the brake pads inspected at a specialist garage
between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain con-
ditions such as when driving through water, during heavy rain showers or after
the vehicle has been washed in an automatic vehicle wash, since the brake discs
and brake pads may be moist or even have a coating of ice on them in winter. You
should dry the brakes as soon as possible by applying and releasing the brakes
several times.
There also may be a certain delay before the full braking efficiency is available
when driving on roads which have been treated with road salt if you have not
used the brakes for some considerable time beforehand. The layer of salt on the
brake discs and brake pads must first be rubbed off when you apply the brakes.
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 sys-
tem.
We recommend cleaning the brake discs by firmly applying the brakes at a fairly
high speed if you do not make much use of the braking system or if surface corro-
sion is present ⇒  .
Faults in the brake surface
If you notice that the braking distance has suddenly become longer and that the
brake pedal can be depressed further, it is possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist ga-
rage without delay in order to have the problem rectified. Drive at a reduced
speed while on your way to the dealer and adapt your style of driving to the high-
er brake pedal pressure required. £ 127
