WARNING
Never seek to adjust the trip counter for distance driven while driving for
safety reasons!
Service Interval Display
Depending on the equipment installed in the vehicle, the information appears in
the display of the counter for distance driven or in the information display ⇒fig. 5 .
Service Interval Display
If the due date for the service is reached, the following text appears after switching
on the ignition:
in the display of the trip counter Service 1 500 km
in information display SERVICE in 1500 km
Prior to the due date for the service the kilometre readout decreases in steps of 100
km. As soon as the due date for the service is reached, the following text appears:
in the display of the trip counter Service in information display
SERVICE NOW
The display disappears within 20 seconds after starting the engine. The trip counter
is also displayed after pressing the reset bu tton of the trip counter (for more than 1
second).
Resetting Service Interval Display
We recommend having this resetting performed by a specialist garage.
The specialist garage:
•resets the memory of the display after the appropriate inspection,
•makes an entry in the Service schedule,
•affix the sticker with the entry of the following service interval to the side of the
dash panel on the driver's side.
It is also possible for you to reset the Se rvice Interval Display with the reset button
⇒ fig. 5 as follows (does not apply to models with fixed service intervals - QG2).
•Switch off the ignition (if not already of f), press the reset button and hold it
down.
•Switch the ignition on and release the reset button . The text Service or
service now appears in the display.
•Turn the button for resetting the clock to the right - the display is reset.
Caution
We recommend that you do not reset the Service Interval Display yourself other-
wise this can result in the service interval display being incorrectly set, which may
also result in problems with operation of your vehicle.
Note
•Never reset the display between service intervals otherwise this may result in
incorrect readouts.
•information is retained in the Service Interval Display also after the battery of
the vehicle is disconnected.

•it is necessary to re-code the Service Interval Display if a new instrument cluster
is installed during repair work. This work is carried out by a specialist garage.
•After resetting the display with flexible service intervals (QG1) using the reset
button , the data displayed are the same as for a car with fixed service intervals
(QG2). We therefore recommend having the Service Interval Display reset only by a
Škoda Service Partner who is familiar with the procedure for resetting the display
with a vehicle system tester.
•Please refer to the brochure Service sc hedule for extensive information about
the service intervals.
Multi-functional indicator (onboard computer)
Introduction
The multi-functional indicator appears in the display of the revolutions counter
⇒ page 11, fig. 2 or in the information display ⇒fig. 6 depending on the equip-
ment fitted to your vehicle.
The multi-functional indicator offers you a range of useful information.

Airbag system

Deactivating an airbag
Deactivating airbags
If any airbags have been deactivated, switch them on again as soon
as possible so that they are able to again provide their proper protec-
tion.
There is the technical means installed within your vehicle to switch off the front,
side or head airbag (take out of commission).
This is why you should have the deactiva tion of the airbags carried out by a
specialist garage.
On vehicles equipped with the switch for deactivation of the airbags, you can deac-
tivate the front and side passenger airbag by means of this switch ⇒page 144.
Deactivation of airbags is envisaged only for particular instances, such as if:
•you must in exceptional cases use a child seat on the front passenger seat
where the child has its back to the directio n of travel of the vehicle (in some coun-
tries this must be in the direction of trav el due to other legal regulations applying)
⇒ page 146, “Important safety information regarding the use of child safety seats”
•you are not able to maintain the distance of at least 25 cm between middle of
steering wheel and chest, despite the driver seat being correctly adjusted,
•special attachments are required in the area of the steering wheel because of a
physical disability,
•you have installed other seats (e.g. orthopaedic seats without side airbags).
Monitoring the airbag system
The functionality of the airbag system is also monitored electronically, when one
airbag has been switched off
If the airbag was switched off using diagnostic equipment:
•The warning light for the airbag system lights up for 3 seconds after switching
on the ignition and then flashes for 12 seconds afterwards in 2 second intervals.
Front passenger airbags sw itched off using the switch for front passenger
airbags* in stowage compartmen t on the front passenger side:
•The airbag warning light comes on in th e instrument cluster for about 3 seconds
each time the ignition is switched on.
•Switching off airbags is indicated in the middle of the dash panel by the lighting
up of the indicator light   ⇒ fig. 153 .
Note
Your Škoda Service Partner will be able to advise you whether national legislation in
your country allows airbags in your vehicle to be deactivated, and which ones.

Driving and the Environment165
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Avoiding full throttle
Driving more slowly means saving fuel.
Sensitive use of the accelerator will not only significantly reduce fuel consumption
but also positively influence environmental pollution and wear of your vehicle.
You should avoid fully exploiting the top speed of your vehicle wherever possible.
Fuel consumption, pollutant emissions and vehicle noises increase disproportion-
ally at high speeds.
The ⇒fig. 167 shows the ratio of fuel consumptio n to the speed of your vehicle.
You will cut your fuel consumption by half if you only make use three-quarters of
the possible top speed of your vehicle.
Reducing idling
Idling also costs fuel.
It is worthwhile switching off the engine in a traffic jam or when waiting at a level
crossing or at traffic lights with a length y red phase. Even after just 30 - 40 seconds
you will have saved more fuel than that is needed when you start the engine up
again.
If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant em issions, though, are particularly high in the warming-up phase. This is why you should drive off right after starting the
engine. Do avoid high engine re
volutions at this time, however.
Regular servicing
A poorly tuned engine consumes an unnecessarily high amount of
fuel.
Having your vehicle serviced regularly at a specialist garge enables you to satisfy
one of the requirements for economical motoring even before you set off on your
journey. Keeping your vehicle properly serviced not only has a positive effect on the
safety of your vehicle and maintaining its value, but also saves on fuel.
A poorly tuned engine can result in a fu el consumption which is 10% higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refueling. Oil consumption is dependent to a consid-
erable extent on the load and speed of the engine. Oil consumption could be as
high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine ha s a higher oil consumption at first, and
reaches its lowest level only after a certain running in time. It is therefore not
possible to correctly assess the oil cons umption of a new vehicle until after you
have driven about 5 000 km.
For the sake of the environment
•You can achieve additional improvements in your fuel economy by using high-
lubricity oils.
•Check the ground below your car at regula r intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garge if you find any
stains caused by oil or other fluids on the floor.

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 the aid of the headlight beam adjuster
⇒ page 48.
Detachable ball head
The ball rod is detachable on vehicles wh ich 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 171.
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 temper ature 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/h for safety reasons. This also applies for countries
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 engi ne speed when the outside temperature is
very high ⇒page 12.
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 190, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 26, “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
