2011 SKODA ROOMSTER brake sensor

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

WARNING
● The parking aid is not a substitute for the driver paying proper attention
and it is always the driver's responsibility to take care when parking the vehi-
cle or carrying out similar manoeuvres.
● You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar, etc., behind your ve-
hicle. Such an obstacle might not be within the range detected by the sensors.
● Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the parking aid. Thus, these objects or
people who wear such clothing are not recognised by the sensors of the park-
ing aid. Note
● The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fitted towing device).
● A system fault is indicated if a warning signal sounds for about 5 seconds after
switching the ignition on and engaging reverse gear and there is no obstacle close
to your vehicle. It is possible that the audible warning does not function correctly
(an obstacle behind the vehicle may not be detected - take extra care). Have the
fault rectified by a specialist workshop.
● If the audible warning sounds for 3 seconds after switching the ignition on and
engaging the reverse gear, a fault has occurred in the system. It is possible that
the audible warning does not function correctly (an obstacle behind the vehicle
may not be detected - take extra care). Have the fault rectified by a specialist
workshop.
● The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
● If the parking aid is activated and the selector lever of the automatic gearbox
is in the position P , warning signal indicates interruption (vehicle can no longer
move). Cruise control system (CCS)
Introduction The cruise control system (CCS) maintains a constant speed, more than 30 km/h
(20 mph), once it has been set, without you having to depress the accelerator
pedal. This is only possible within the range which is permitted by the power out-
put and braking power of the engine. The cruise control system makes it possible
- particularly on long journeys - for you to rest your
“accelerator foot”. WARNING
● For safety reasons, the cruise control system must not be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads,
loose gravel) - risk of accident!
● In order to prevent unintentional use of the cruise control system, always
switch off the system after use. Note
● Models fitted with a manual gearbox: Always depress the clutch pedal if you
switch on the cruise control system when the gearbox is in Neutral! Otherwise the
engine can rev up unintentionally.
● The cruise control system is not able to maintain a constant speed when driv-
ing on steep downhill sections. The weight of the vehicle increases the speed at
which it travels. One should shift down in good time to a lower gear or slow the
vehicle down by applying the foot brake.
● It is not possible on vehicles fitted with an automatic gearbox to switch on the
cruise control system if the selector lever is in the position P, N or R.  83

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.
The TCS warning light lights up in the instrument cluster when there is a fault on
the TCS  ⇒  page 24. £126
