Dual clutch gearbox DSG®
r-('n First read and observe the Introductory L-.lo:on Information and safety warnings & on page 260.
Description
The DSG® dual clutch gearbox is a gearbox which uses dual-clutch technology to change gear automatically. it uses a dual clutch and two independent gearboxes to enable very fast gear changes with no loss of torque. The DSG® dual clutch gearbox thus combines the performance and economy of a manual gearbox with the com-fort and convenience of a conventional automatic transmission.
How the system works
Engine power is transferred to the drive shafts via the gearbox. In order to change gears, the power transmission between the engine and the gearbox has to be interrupted. This is what the clutch is for.
With the DSG® dual clutch system with its two complementary gearboxes, one gearbox is always connected under load to the engine. When one gear is engaged, another gear is always preselec-
led in the other gearbox. The clutch on the non-driven gear is closed and the other is opened at the same time. This is what makes very fast gear changes possible.
The DSG® dual clutch gearbox is designed to be more efficient than an automatic gearbox. In an au-tomatic gearbox, the torque converter is constantly in use, whereas in the DSG® dual clutch system the idle clutch can be opened, thus saving fuel. With its efficiency, low weight and intelligent control system, the DSG® dual clutch system usually ena-bles fuel consumption equal to or lower than a manual gearbox.
like the manual gearbox, the clutch in the DSG dual clutch system is subject to wear. Regular maintenance is necessary, varying accord-ing to what type of DSG® dual clutch system is in-stalled. For more information see the service schedule. In the DSG® dual clutch system, if one gearbox malfunctions it is deactivated and the oth-er gearbox functions alone *page 267. If this happens, have the system checked as soon as possible by a qualified workshop. DSG® dual clutch gearbox: selecting a gear

The selector lever is equipped with a selector lever lock. When changing the selector lever position from P to a driving gear, depress the brake pedal and push the lock button in the selector lever in the direction of the arrow *Fig. 221. To move the se-lector lever out of position N to position D or R, first depress and hold the brake pedal.
The current selector lever position or the selected gear will be shown in the instrument duster display if the ignition is switched on. .,..

Selector lever lock
The selector lever lock in position P or N prevents gears from being engaged inadvertently, which would cause the vehicle to move.
To release the selector lever lock in the position P or N while the ignition is switched on, depress the brake pedal and hold. Press the lock button in the selector lever at the same time.
The selector lever lock is not engaged if the selec-tor lever Is moved quickly through position N, e.g. when shifting from R to D. This makes it possible, for Instance, to "rock" the vehicle backwards and forwards if it is stuck in snow or mud. The selector lever lock engages automatically if the brake pedal is not depressed and the lever is in position N for more than approximately 1 second and the vehicle is travelling no faster than approximately 5 km/h (3 mph).
In rare cases, the selector lever lock may not en-gage in vehicles with a DSG® dual clutch gearbox. The drive is then deactivated to prevent the vehicle from accidentally pulling away. The green indicator lamp IS> flashes and an information message is al-so displayed. Use the following procedure to en-gage the selector lever lock:
• Depress the foot brake and then release it again.
,A WARNING
Engaging an incorrect selector lever position can cause you to lose control of the vehicle, which can lead to accidents and serious inju-ries.
• Never depress the accelerator pedal when selecting a position.
• When the engine is running, the vehicle starts moving as soon as a selector lever po-sition is engaged and the brake pedal Is re-leased.
• Never select reverse gear or engage the parking lock while the vehicle Is In motion.
A WARNING
Unintentional vehicle movements can cause serious Injury.
• The driver must never leave the driver seat when the engine is running and a posi-tion has been selected. If you have to leave the vehicle while the engine Is running, al-ways apply the handbrake and move the se-lector lever to position P.
• If the engine is running and the selector lever Is in position D, S or R, the vehicle must be held with the foot brake. The vehicle will creep forward even when the engine Is idling, as power transmission Is even then not fully Interrupted.
• Never select positions R or P when the ve-hicle is In motion.
Starting the engine, changing gear and parking 265

• Reduce your speed.
• Push the selector lever from position D to the right into the Tiptronic gate 266.
• Gently push the selector lever to the rear to change down gear.
Stopping the vehicle and pulling away when driving uphill
The steeper the incline, the lower the gear that is required.
If you wish to stop the vehicle or pull away when driving uphill, you should use the Hill Hold Assist function 282.
Vehicles without Hill Hold Assist: when the vehi-cle is stopped on an incline and remains in gear, the vehicle must always be prevented from rolling by depressing the brake pedal or by applying the handbrake. The brake pedal or the handbrake should not be released until you start to pull away
Kickdown
The kickdown mechanism enables maximum ac-celeration in the selector lever positions D and S, or in the Tiptronic position.
If the accelerator pedal is depressed fully, the gear-box will automatically shift to a lower gear, depend-ing on the speed and engine revs. This will make use of the full vehicle acceleration &.
The gearbox does not shift up to the next gear until the engine reaches the maximum engine speed for the gear.
Freewheel driving with 7-speed dual clutch gearbox DSG®
In coasting mode, the momentum of the vehicle can be used to save fuel in conjunction with a fore-sighted driving style. The engine is declutched and no longer brakes the vehicle -the vehicle can roll out over a longer distance.
Switch-on condition: the selector lever must be in position D.
