Electronic stability programme (ESP)*
General
General
The ESP aids you maintain control of your vehicle in situations in borderline driving
situations such as when negotiating a curve too fast. The risk of skidding is reduced
and your car thus offers greater driving stability depending on the conditions of the
road surface. This occurs at all speeds.
The following systems are integrated into the electronic stability programme:
•Electronic Differential Lock (EDL),
•Traction control system (TCS),
•Driver-steering recommendation,
•Antilock brake system (ABS),
•Brake Assist,
•Uphill-Start off-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 also
processes additional measurement data which are supplied by highly sensitive
sensors: the rotational velocity of the vehi
cle about its vertical axis, the lateral accel-
eration of the vehicle, the brakin g pressure and the steering angle.
The direction which the driver wishes to ta ke is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual
behaviour of the vehicle. If differences exis t, 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 re ar wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied
by noises.
The ESP operates in combination with the ABS ⇒page 185, “Antilock brake system
(ABS)”. If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light ⇒page 32 lights up in the instrument cluster when there is a
fault on the ESP.
Switching off
You can switch the ESP off and on again as you wish, by pressing the button
⇒ fig. 184 . The ESP warning light ⇒page 32 lights up in the instrument cluster
when the ESP is switched off.
The ESP 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.

Traction control system (TCS)
The traction control system prevents the driven wheels from spinning
when accelerating.
General
The TCS makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditio ns of the road surface are unfavourable.
Operating principle
The TCS switches on automatically when th e 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 surface is
automatically adapted by redu cing the engine speed. This occurs at all speeds.
The TCS operates in combination with the ABS ⇒page 185, “Antilock brake system
(ABS)”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light ⇒page 31 lights up in the instrument cluster when there is a
fault on the TCS.
Switching off
You can switch the TCS off and on again as you wish by pressing the button
⇒ fig. 185 . The TCS warning light ⇒page 31 lights up in the instrument cluster
when the TCS is switched off. 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
•when it is necessary to rock a car free when it has become stuck.
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 problem-
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 other assign-
ment of tyres and wheels) can in fluence the function of the TCS ⇒page 229,
“Accessories, changes and replacement of parts”.
Driver-steering recommendation*
The driver-steering recommendation is an additional function of the electronic
stability programme (ESP). This function indicates to the driver in critical situations
by means of slight steering wheel impulses the direction evaluated by the system,
in which the vehicle must be steered, so that it stabilizes. The driver-steering
recommendation is active when braking shar ply on different road surfaces and on
the right and left vehicle side.

Intelligent Technology

The majority of drivers do apply the brakes in good time in dangerous situations,
but do not depress the brake pedal with su fficient pressure. Consequently, it is not
possible for the car to achieve its maximum deceleration and the car covers a
greater distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In such
cases, a much greater braking pressure ex ists than during a normal brake applica-
tion. This makes it possible, even with a relatively low resistance of the brake pedal,
to produce an adequate pressure in the brake system in the shortest possible time,
which is required for maximum deceleration of the car. You must apply the brake
pedal firmly and hold it in this position in order to achieve the shortest possible
braking distance.
The Brake Assist is able to help you achieve a shorter braking distance in emergency
situations by rapidly producing the pressure required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function of
the Brake Assist is automatically switched off and the brakes operate in the normal
way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist
function is also not available. Further information on the ESP ⇒page 181.
WARNING
•The Brake Assist is also not able to overcome the physical limits of your
car in terms of the braking distance required.
•Adapt your speed to the conditions of the road surface and to the traffic
situation.
•The increased safety offered by the Brake Assist must not tempt you to
take a greater safety risk than otherwise.
Uphill-Start off-Assist*
The uphill-start off-assist makes it much easier to start off on steep hills. The system
assists a start off by holding the brake pr essure produced by the brake pedal actu-
ation for approx. 2 seconds after releasing the brake pedal. The driver can therefore
move his foot from the brake pedal to the accelerator pedal and start off on the slope, without having to actuate the hand
brake. The brake pressure drops gradually
the more you operate the accelerator pedal. If the vehicle does not start off within
2 seconds, it starts to roll back.
The uphill-start off-assist is active in the ev ent of a 5% slope, if the vehicle door is
closed. It is alwa ys active on slopes when in forward or reverse start off. When
driving downhill, it is inactive.
Electromechanical power steering
The power steering enables you to steer the vehicle with less physical force.
With the electromechanical power steering, the steering assist is automatically
adapted to the speed and to the steering angle.
It is still possible to fully steer the vehicle if the power steering fails or if the engine
is not running (vehicle being towed in). The only difference is that greater physical
effort is required.
If there is a fault in the power steering, a red or yellow warning light
 lights up in
the instrument cluster ⇒page 27.
WARNING
Contact your specialist garage if the power steering is defective.

Tyre inflation pressure-control system*
The tyre inflation pressure-control system compares with the aid of the ABS sensors
the speed and also the rolling circumference of the individual wheels. If the rolling
circumference of a wheel is changed, the warning light
 lights up in the dash
panel insert ⇒page 30. The rolling circumference of the tyre can change if:
•the tyre inflation pressure is too low,
•the structure of the tyre is damaged,
•the vehicle is loaded on one side,
•the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill),
•snow chains are mounted,
•the temporary spare wheel is mounted,
•one wheel per axle was changed.
Basic setting of tyre inflation pressure-control system
After changing the tyre inflation pressures or after changing one or several wheels,
a basic setting of the system must be carried out as follows.
•Inflate all tyres to the specified inflation pressure ⇒page 223.
•Switch on the ignition.
•Press button   ⇒ fig. 186 for more than 2 second s. While pressing the
button, the warning light  lights up. At the same time the basic values are stored,
which is confirmed with an acoustic sound and then the warning light  goes out.
•If the warning light  does not go out after the basic setting, there is a fault in
the system. Have the vehicle inspected by your nearest specialist garage.
Warning light
 lights up
If the tyre inflation pressure of at least on e wheel is insufficiently inflated in compar-
ison to the stored basic value, the warning light
 ⇒ lights up.
Warning light
 flashes
If the warning light flashes, there is a system fault. Have the vehicle inspected by
your nearest specialist garage.
WARNING
•When the warning light  lights up, immediately reduce the speed and
avoid sudden steering and brake mano euvres. Please stop the vehicle
without delay at the nearest possible stop and inspect the tyres and their
inflation pressures.
•The driver is responsible for the correc t tyre inflation pressures. For this
reason, the tyre inflation pressures must be checked regularly.
•Under certain circumstances (e.g. sporty style of driving, wintry or
unpaved roads) the warning light  can be delayed or does not light up at
all.
•The tyre inflation pressure-control system does not take away the
responsability from the driver for the correct tyre inflation pressure.
Note
The tyre inflation pressure-control system:
•does not replace the regular tyre inflatio n pressure control, because the system
cannot detect an even pressure loss,
•cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of
sudden tyre damage. In this case carefully bring the vehicle to a standstill without
sudden steering movements and without sharp braking.

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 55.
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 198.
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.
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 215, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 28, “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

Disconnecting and reconnecting the battery
On disconnecting and reconnecting the batte ry the following functions are initially
deactivated or are no longer able to operate fault-free.
We recommend having the ve hicle 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 ba ttery 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 loca l environmental protection regulations and
on no account as domestic waste.
Windshield washer system
The windshield washer reservoir 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. 203 .
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 accessories (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
•If you find yourself in flowing traffic switch on the hazard warning lights
system and place the warning triangle on the side of the road at the
prescribed distance from your vehicl e while observing all national legal
provisions. In this way you are protecting not only yourself but also other
road users.
•Never start the engine with the vehicle sitting on the raised jack - danger
of suffering injury!
Caution
If you have to change a wheel on a slope first block the opposite wheel with a stone
or similar object in order to secure th e vehicle from unexpectedly rolling away.
Note
Comply with the national legal regulations.
Changing a wheel
Always change a wheel on a level surface as far as possible.
– Take off the full wheel trim* ⇒page 235 or the caps ⇒page 235.
– In the case of light alloy wheels remove the wheel trim cap ⇒page 236.
– Slacken the wheel bolts ⇒page 236.
– Jack up the vehicle until the wheel to be changed is clear of the ground
⇒ page 237.
– Unscrew the wheel bolts and place them on a clean surface (cloth, paper etc.).
– Take off the wheel. – Fit on the spare wheel and tighten the wheel bolts slightly.
– Lower the car.
– Tighten the wheel bolts firmly, al
ternately and diagonally using the
wheel wrench ⇒page 236.
– Mount the full wheel trim/w heel trim cap or the caps.
Note
•All bolts must be clean and must turn easily.
•You must never grease or oil the wheel bolts!
•When fitting on unidirectional tyres, ensure that the tyres rotate in the correct
direction ⇒page 223.
Subsequent steps
After changing the wheel, you must perform the following steps.
– Stow and attach the replaced wheel in the spare wheel well.
– Stow the vehicle tool kit in the space provided.
– Check the tyre pressure on the spare wheel just mounted as soon as
possible.
– Have the tightening torque of the wheel bolts checked with a torque
wrench as soon as possible. Steel and light alloy wheels must be tight-
ened to a tightening torque of 120 Nm.
– Have the defective tyre repaired as soon as possible.
WARNING
It is necessary to observe the guidelines given on ⇒page 225, “New tyres
and wheels” if the vehicle is subseq uently fitted with tyres which are
different to those it was fitted with at the works.
