When are the airbags deployed?The airbag system is designed in such a wa y that the driver and front passenger airbag
are deployed in the event of a violent frontal collision.
In the case of a violent side collision , the side airbag* on the side of the vehicle at
which the collision occurs, is deployed to gether with the relevant head airbag*.
In special cases, the front as well as th e relevant side and head airbags may be
deployed together.
The airbags are not deployed in the case of minor frontal and side collisions, in the
case of rear-end collisi ons and vehicle rollover.
Deployment factors
It is not possible to state globally which deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of accidents vary
greatly. An important role in this case is played by factors such as the type of object
against which the vehicle impacts (hard, soft ), the angle of impact, the relative speed
during the accident etc.
A decisive factor for the deployment of the airbags is the deceleration which occurs
during a collision. The control unit analyses the nature of the collision and activates the
relevant restraint system. If the vehicle deceleration which occurs and is measured
during the collision remains below the prescribed reference values specified in the
control unit, the airbags are no t deployed although the vehicle may well suffer severe
damage to the bodywork as a consequence of the accident.
The airbags are not deployed if:
ignition off,

a minor frontal collision,

a minor side collision,

a rear-end collision,

Rollover of the vehicle.Note

A grey white, non harmful gas is released when airbag is inflated. This is perfectly
normal and is not an indicati on of a fire in the vehicle.

In the event of an accident in which the airbags are deployed:
The interior lighting comes on (if the switch for the interior light is in the door
contact position),
 The hazard warning light is switched on,
 All the doors are unlocked,
 the fuel supply to the engine is interrupted.
Front airbagsDescription of the front airbags
The airbag system is not a su bstitute for the seat belt!Fig. 133 Driver airbag in th e steering wheel / front passenger airbag in the dash panelThe front airbag for the driver is housed in the steering wheel fig. 133 - left. The front
airbag for the front passenger* is housed in the dash panel above the storage compart-
ment fig. 133 - right. The installation positions are each marked with the “AIRBAG”
logo.
The front airbag system, in combination with three-point safety belts, offers additional
protection for the head and chest area of the driver and front passenger in the event of
a frontal collision of major severity  page 152.
The airbag is not a substitute for the seat belt, but is part of the complete passive
vehicle safety concept. Please note that an airbag can only offer you optimal
protection in combination with a seat belt which is fastened .

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralThe 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 vehicle 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),

active driver-steering recommendation (DSR),

Antilock brake system (ABS),

Brake Assist,

Uphill Start Assist
The ESP system cannot be switched off, only the TCS system can be switched off by
pressing the button fig. 149 , the warning light
 lights up. 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 proc-
esses additional measurement data which are supplied by highly sensitive sensors: the
rotational velocity of the vehicle about its ve
rtical axis, the lateral acceleration 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 co nstantly compared with the actual behav-
iour of the vehicle. If differences exist, such as the vehi cle beginning to skid, the ESP will
automatically brake the appropriate wheel.
The car is stabilised again by the forces wh ich 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 wh eel 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 in the instrument
cluster page 32.
The ESP operates in combination with the ABS page 171, “Antilock brake system
(ABS)”. If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light lights up in the instrument cluster when there is a fault on the
ESP
  page 32.WARNING
It is also not possible for the ESP to overcome the physical limits of the vehicle.
Even if a vehicle fitted with ESP you should still always adapt your style of
driving to the condition of the road surfac e and the traffic situation. This partic-
ularly 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 acci-
dent!
Note

All four wheels must be fitted with the same tyres in order to achieve problem-free
operation of the ESP. Differing rolling circum ferences of the tyres can lead to an unde-
sirable reduction in the engine output.

Changes to vehicle (e.g. on engine, on th e brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the ESP page 214, “Accesso-
ries, changes and replacement of parts”.
Electronic Differential Lock (EDL and XDL)*
The electronic differential lock prev ents an individual wheel from slip-
ping.Models fitted with ESP ar e equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The EDL is activated automaticall y, 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 sensors. 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 greate r driving force to the other driven wheel.
This control process is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatica lly 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.
XDL function (only for Octavia RS)
The XDL function is an extension to the electronic differential lock. The XDL function
does not respond to traction, but to the relief of the inner front wheel during fast
cornering. An active brake intervention on the brake of the inner wheel prevents it from
spinning. Thus, the trac tion is improved and the vehicle continues to follow the desired
track.
WARNING

Carefully depress the accelerator when accelerating on uniformly slippery
road surfaces, such as ice and snow. Th e 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
surface 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
otherwise - risk of an accident!Note

If the ABS or ESP warning light comes on, this may also indicate a fault in the EDL.
Please have the vehicle inspected as soon as possible by a specialist garage.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the EDL page 214, “Accesso-
ries, changes and replacement of parts”.

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 th e conditions 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 auto-
matically adapted by reducing the engine speed. The system operates at all speeds.
The TCS operates in combination with the ABS page 171, “Antilock brake system
(ABS)”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light lights up in the instru ment cluster when there is a fault on the
TCS
  page 32.
During an intervention of the system, the TCS warning light
 flashes in the instru-
ment cluster page 32.
Switching off
You can switch the TCS off and on again as you wish by pressing the button fig. 150 .
The TCS warning light lights up in the instru ment cluster when the system is switched
off
  page 32. 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 vehicle 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 unde-
sirable reduction in the engine output.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the TCS page 214, “Accesso-
ries, changes and replacement of parts”.
Active driver-steering recommendation (DSR)*Vehicles with ESP are equipped with active driver-steering recommendation (DSR).
This function indicates to the driver in crit ical situations a steering recommendation in
order to stabilise the vehicle. The active driver-steering recommendation is activated,
for example, on the right and left vehicle si de when braking sharply on different road
surfaces.
WARNING
Even with this function the vehicle cann ot steer itself! The driver is furthermore
responsible for the steering of the vehicle!

Brake boosterThe brake booster boosts the pressure which you generate with the brake pedal. The
necessary pressure is only genera ted when the engine is running.
WARNING

Never switch off the engine before the vehicle is stationary.

The brake booster only operates when the engine is running. Greater phys-
ical effort for braking is required when en gine is switched off. Because if you do
not stop as normal, this can cause an accident and severe injuries.
Antilock brake system (ABS)ABS prevents the wheels locking when braking.General
The ABS contributes significantly to enhanc ing the active safety of your vehicle.
Compared to a vehicle not fitted with the ABS brake system, you are able to retain
optimal steering ability even during a full br ake application on a slippery road surface
because the wheels do not lock up.
You must not expect, however, that the br aking distance will be shorter under all
circumstances as a result of the ABS. The braking distance for example on gravel and
fresh snow, when you should anyway be driving slowly and cautiously, will be longer.
Operating principle
The brake pressure will be reduced on a wheel which is rotating at a speed which is too
low for the speed of the vehicle and tending to lock. This control cycle is noticeable
from a pulsating movement of the brake pedal which is accompanied by noises.
This is consciously intended to provide the driver with the information that the wheels
are tending to lock (ABS control range) . You must always keep the brake pedal
depressed to enable the ABS to optimally control the brake application in this braking
range. Never interrupt the application of the brakes!
WARNING

The ABS can also not overcome the physical limits of your vehicle. Please do
not forget this, particularly when driving on icy or wet road surfaces. If the ABS
is operating within the control range, adapt your speed immediately to the
conditions of the road surface and the traffic situation. The increased safety
offered by the ABS 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 specialist garage as quickly as poss ible and adjust your style of driving to
take account of the ABS fault in the meantime since you will not know the extent
of the fault and in how far the braking efficiency is affected.Note

A warning light comes on if a fault occurs in the ABS system
  page 33.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can in fluence the function of the ABS page 214, “Accesso-
ries, changes and replacement of parts”.
Brake Assist*During a severe brake application (e.g. if a hazard exists), the Brake Assist increases the
braking force and thus makes it possible to rapidly produce the pressure required in
the brake system.
The majority of drivers do a pply the brakes in good time in dangerous situations, but
do not depress the brake pedal with sufficient pressure. Consequently, it is not possible
for the vehicle to achieve its maximum deceleration and the vehicle covers a greater
distance than necessary.
The Brake Assist is activated by the very qu ick operation of the brake pedal. In such
cases, a much greater braking pressure exists than during a normal brake application.
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 dece leration of the vehicle. You must apply the brake pedal
firmly and hold it in this position in or der 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 167.
WARNING

The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the braking distance required.

Adapt your speed to the conditions of the road surface and to the traffic situ-
ation.

The increased safety offered by the Brake Assist must not tempt you to take
a greater safety risk than otherwise.
Uphill Start Assist*The uphill start assist makes it easier to start off on steep hills. The system assists a start
off by holding the brake pressure produced by the brake pedal actuation 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 handbrake. 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 assist is active as of a 5 % slope, if the driver door is closed. It is always
active on slopes when in forward or reverse start off. When driving downhill, it is
inactive.Electromechanical power steeringThe power steering enables you to steer the vehicle with le ss 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, the warning light
 or  lights up in the instru-
ment cluster page 30.
WARNING
Contact your specialist garage if the power steering is defective.Tyre pressure monitoring system*The tyre pressure monitoring system compares with the aid of the ABS sensors the
speed and also the rolling circumference of the individual wheels. If the rolling circum-
ference of a wheel is changed, the warning light
 lights up in the instrument cluster
 page 33 and an audible signal sounds. 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,

Basic setting of the system
After changing the tyre inflation pressures, after changing one or several wheels, the
position of a wheel on the vehicle (e.g. exch anging the wheels between the axles) or
when the warning light lights up while drivin g, a basic setting of the system must be
carried out as follows.

Inflate all tyres to the specified inflation pressure page 208.

Switch on the ignition.

Press button  page 172, fig. 151 for more than 2 seconds. While pressing
the button, the warning light
 lights up. At the same time the memory of the system
is erased and the new calibration is started, which is confirmed with an audible signal
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 one wheel is insufficiently inflated in comparison
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 manoeuvr es. Please stop the vehicle without
delay at the nearest possible stop and in spect the tyres and their inflation pres-
sures.

The driver is responsible for the correct tyre inflation pressures. For this
reason, the tyre inflation pressu res 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 pressure monitoring system does not take away the responsibility
from the driver for the correct tyre inflation pressure.
Note
The tyre pressure monitoring 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 ca refully bring the vehicle to a standstill without sudden
steering movements and without sharp braking.

In order to ensure a proper functioning of the tyre inflation pressure-control
system, it is necessary to carry out the ba sic setting again every 10 000 km or 1x a
year.
Diesel particle filter* (diesel engine)In the diesel particle filter the resu lting soot particles are collected and
burnt during the combustion of diesel fuel.Code 7GG, 7MB or 7MG on the vehicle data sticker, see fig. 152 , indicates that your
vehicle is equipped with a diesel particle fi lter. The vehicle data sticker is located on
the floor of the luggage compartment and is also stated in the Service schedule.
The diesel particle filter filters the soot particles completely from the exhaust. The soot
is collected in the diesel particle filter and burnt regularly. To assist this procedure, we
recommend not to drive regu larly over short distances.
