2008 SKODA ROOMSTER wheel torque

Automatic gearbox100
gearbox does not shift up into the highest gear until the engine has reached its maximum revolutions for this gear range.
WARNING
Please note that using the kickdown fu nction can result in the driven wheels spinning on a smooth or slippery road surface - risk of skidding!
Dynamic shift programme
The automatic gearbox of your vehicle is controlled electronically. Shifting up and down through the gears is performed auto matically on the basis of pre-defined driving programmes.
Adopting a moderate style of driving will cause the gearbox to select the most economical driving programme. Shifting up into a higher gear as soon as possible and shifting down as late as possible will have a favourable effect on your fuel consumption.
Adopting a sporty style of driving with rapid movements of the accelerator pedal combined with sharp acceleration and frequent changes in speed, exploiting the top speed of the car or depressing the a ccelerator pedal (kickdown function), will cause the gearbox to switch over to this style of driving and shift down earlier with frequent changes in gears in comparison to the moderate style of driving.
Selecting the most appropriate driving programme for the particular style of driving is a continuous process. Irrespective of this it is, however, possible to switch or shift down into a dynamic shift programme by depressing the accelerator rapidly. The gearbox shifts down into a lower gear matc hing the speed of the car and this allows you to accelerate rapidly (e.g. when ov ertaking) without having to depress the accelerator pedal fully into the kickdown range. The original programme will be reactivated to match your part icular style of driving once the gearbox has shifted up again.
When driving in hilly regions, the gears are selected to match uphill and downhill sections. This avoids the ge arbox frequently shifting up and down when negotiating an uphill stretch. When driving downhill, it is possible to shift down into the Tiptronic position, in order to exploit the engine brake torque.
Tiptronic
The Tiptronic allows the driver to also shift gears manually.
Switching over to manual shifting
– Push the selector lever to the right out of position D. As soon as the
gearbox has switched over, 6 5 4 3 2 1 appears in the display, with the
gear engaged being highlighted.
Shifting up gears
– One-touch forward of the selector lever (in the Tiptronic position)

Wheels and Tyres190
WARNING
•Only use those tyres or wheel rims which have been approved for your model of Škoda Auto a.s. vehicle. Failure to observe this instruction will adversely affect the road safety of your vehicle - risk of accident! Approval and licencing of your vehicle on public roads may also become void as a result.
•You must on no account drive at a higher speed than is permissible for y our t yre s - ris k of a n ac cid e n t re su lti ng fro m ty re d a m ag e a nd lo ss o f c ont rol over your vehicle.
•Tyres which are 6 years old or more should only be fitted in exceptional cases and when adopting an appropriately cautious style of driving.
•Never fit tyres which have already been used without having adequate knowledge of their previous history. Ty res age even if they have not been used at all or only very little. A spare tyre must only be used in exceptional cases and only then when adopting an appropriately cautious style of driving.
•Do not, where possible, replace indivi dual tyres but at least replace them on both wheels of a given axle at the same time. Always fit the tyres with the deeper tread depth to the front wheels.
For the sake of the environment
Old tyres must be disposed of in conformity with the appropriate regulations.
Note
It is not normally possible to fit wheels from other models of cars for technical reasons. This may also apply in certain circumstances to the wheels of the same type of vehicle.
Wheel bolts
Wheels and wheel bolts are matched to each other in terms of design. Each time you fit other wheels - e.g. light alloy wheels or wheels with winter tyres - you must
therefore also use the matching wheel bolts of the correct length and shape of spherical cap. This is essent ial to ensure that the wheels are tightly fitted and that the brake system operates properly.
If you retrofit wheel trims (or have this done), please also ensure that an adequate flow of air remains assured for cooling the brake system.
The Škoda Service Partners are instructed in the technical possibilities which exist regarding converting or retrofitti ng wheels, tyres and wheel trim.
WARNING
•In case of incorrect treatment of the wheel bolts, the wheel can loosen when the car is moving - risk of accident!
•The wheel bolts must be clean and must turn easily. However, they must never be treated with grease or oil.
•If the wheel bolts are tightened to a too low tightening torque, the rim can lossen when the car is moving - risk of accident! A tightening torque which is too high can damage the bolts and threads and this can result in permanent deformation of the contact surfaces on the rims.
Caution
The prescribed tightening torque of the wh eel bolts for steel and light alloy wheels is 120 Nm.
Winter tyres
The handling of your vehicle will be significantly improved when driving on wintry roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow and at temperatures below 7 °C because of their construction (width, rubber blend, tread pattern). This applies in particul ar to vehicles which are equipped with low- profile tyres or high-speed tyres (code index H, V or W on wall of tyre).
Winter tyres must be mounted on all four wheels to obtain the best handling char- acteristics.

– Fit on the spare wheel and tighten the wheel bolts slightly.
–Lower the car.
– Tighten the wheel bolts firmly, alternately and diagonally using the
wheel wrench ⇒page 200.
– Mount the full wheel trim/wheel 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, ensu re that the tyres rotate in the correct direction ⇒page 187.
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. The ti ghtening torque for steel and light
alloy wheels must be 120 Nm.
– Have the defective tyre repaired as soon as possible.
WARNING
It is necessary to observe the guidelines given on ⇒page 189, “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.
Note
•If you find, when changing the wheel, that the wheel bolts are corroded and difficult to turn, the bolts must be replac ed before checking the tightening torque.
•Drive cautiously and only at a moderate speed to a workshop where the tight- ening torque can be checked.
Full wheel trim*
Pulling off
– Hook the clamp found in the vehicle tool kit into the reinforced edge
of the full wheel trim.
– Push the wheel key through the clamp, support the wheel key on the
tyre and pull off the wheel trim ⇒fig. 169.
Installing
– First press the full wheel trim onto the wheel at the valve opening
provided. Then press the full wheel trim into the wheel in such a way
that its entire circumference locks correctly in place.

– Turn the lifting jack up further until the wheel is just clear of the
ground.
Ground below the lifting jack which is soft and slippery can cause the vehicle to slip off the jack. It is therefore always ne cessary to place the lifting jack on a solid surface or use a wide and stable base. Use a non-slip base (e.g. a rubber foot mat) if the surface is smooth, such as cobbled stones, a tiled floor, etc.
WARNING
•Always raise the vehicle with the doors closed - risk of injury.
•Take suitable measures to prevent the base of the lifting jack from slip- ping off - risk of injury!
•Place the lifting jack only on a solid and even surface.
•Not positioning the lifting jack at the specified points can result in damage to the vehicle. The ja ck can also slip off if it does not have sufficient grip - risk of injury!
•Never start the engine if the vehicl e is lifted - risk of accident.
•Never lie under the vehicle if the vehicle is only lifted with the vehicle lifting jack.
•It is important to support the vehicle with suitable supporting blocks if you wish to work under the lifted vehicle - risk of injury!
Securing wheels against being stolen*
You need a special adapter for slackening the safety wheel bolts.
– Pull off the full wheel trim/cap from the wheel hub or cap from the
safety wheel bolt.
– Insert the adapter with its toothed side fully into the inner toothing
of the safety wheel bolt right down in such a way that only the
outer hexagon is jutting out ⇒fig. 174.
– Insert the wheel wrench fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly ⇒page 200.
– Reinstall the full wheel trim/wheel cap after removing the adapter or
place the cap onto th e safety wheel bolt.
– Have the tightening torque checked with a torque wrench as soon as
possible. Steel and light alloy wheels must be tightened to a tightening
torque of 120 Nm.
The safety wheel bolts on vehicles fitted with them (one safety wheel bolt per wheel) can only be loosened or tighten up by using the adapter provided.
It is meaningful to note the code number hammered into the rear side of the adapter or the rear side of the safety wheel bolts. You can obtain a replacement adapter from a Škoda Service Partner, if necessary, by quoting this number.
