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

r-('n First read and observe the Introductory L-.lo:on Information and safety warnings & on page 260.
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. .,..

• 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.

Triggering coasting
• Remove foot from accelerator pedal. The en-gine will be disengaged and run in freewheel mode. The vehicle rolls without the braking effect of the engine.
Cancelling coasting mode
• Depress the brake pedal briefly.
Coasting can be switched on and off in the Set-tings menu of the Volkswagen Information sys-tem 24.
A WARNING
Rapid acceleration can cause loss of traction and skidding, particularly on slippery roads. This can cause you to lose control of the ve-hicle, which can lead to accidents and seri-ous injuries.
• Always adjust your driving style in ac-cordance with the flow of traffic.
• Only use kickdown or fast acceleration if visibility, weather, road and traffic conditions permit, and other road users are not put at risk due to the acceleration and the driving style.
• You should never endanger other road users through the acceleration of your vehi-cle or through your driving style.
CD
• If you stop the vehicle on an incline, do not attempt to stop it from rolling back by depress-Ing the accelerator while a position is still se-lected. The automatic gearbox could overheat and be damaged.
• Never allow the vehicle to roll in position N, particularly if the ignition is switched off. The automatic gearbox will not be lubricated and could be damaged. <1
box is running in an emergency programme. The vehicle can still be driven in the emergency pro-gramme, but only at reduced speed and not in all gears.
In vehicles with a DSG® dual clutch gearbox, you may no longer be able to select reverse gear. The gearbox should be checked by a qualified workshop as soon as possible. .,..
Starting the engine, changing gear and parking 267

In all cases the automatic gearbox should be checked by a qualified workshop Immediately.
Overheating of the DSG® dual clutch gearbox
The dual clutch gearbox can overheat when the vehicle pulls off regularly, travels at a crawl for long periods, or in stop and go traffic. Gearbox over-heating is indicated by the warning lamp (j) and in some cases by a text message in the instrument cluster display. A signal tone may also be given. Stop the vehicle and allow the gearbox to cool down
The vehicle will not move forwards or backwards even though a gear has been selected
If the vehicle will not move in the required direc-tion, the system may have selected the position in-correctly. Depress the brake pedal and reselect the position.
Gear-change indicator
r--f"'n First read and observe the Introductory L-lo:.l.l information and safety warnings & on page 260.
Depending on the vehicle equipment level, the in-strument cluster may indicate the gear which you should select in order to reduce fuel consumption while the vehicle is in motion.
Display Meaning
• The current gear is optimal.
f A higher gear is recommended.
! A lower gear is recommended.
In vehicles with a manual gearbox the recommen-ded gear will be indicated in the form of a number and a recommendation to shift up or down into the recommended gear will be displayed in the form of an arrow 263.
In vehicles with a OSG® dual clutch gearbox if the selector lever is in the Tiptronic position, the cur-rent gear will be indicated in the form of a number and a recommendation to shift up or down a gear will be displayed in the form of an arrow 266.
268 While driving
If the vehicle still does not move in the required di-rection, there is a system fault. Seek expert assis-tance and have the system checked.
CD
• If the display Indicates that the gearbox Is overheating for the first time, the vehicle will have to be parked safely or driven faster than 20 kmlh (12 mph).
• Safely park the vehicle immediately and switch the engine off if the text message and signal tone are repeated approximately every 10 seconds. Allow the gearbox to cool down.
• In order to prevent damage to the gearbox, you should not drive on until the acoustic warning stops. You should not pull away or drive the vehicle at very low speeds while the gearbox is overheated. Information on "cleaning" the diesel partlculate filter
The exhaust management system detects when a diesel particulate filter is filling up and aids the fil-ter's self-cleaning process by recommending the most suitable gear when driving. This may mean driving with Increased engine speed in exceptional cases 407.
A CAUTION
The gear-change Indicator Is only designed to assist the driver and cannot replace the driver's own judgement.
• The driver has full responsibility for se-lecting the correct gear In all situations (e.g. when overtaking, driving up and down hills and when towing a trailer).
Driving in the correct gear can help to reduce fuel consumption.
m On vehicles with a dual clutch gearbox W DSG®, the information on the gear-change indicator disappears when disengaging from the Tiptronic position.
m On vehicles with a manual gearbox, the dis-W play on the gear-change indicator will disap-pear when the clutch pedal is depressed.

A WARNING
Driving with worn brake pads or with a faulty brake system can cause accidents and seri-ous Injuries.
• If the warning lamp 0 lights up either on its own or with a text message In the display of the Instrument cluster, go to a qualified workshop Immediately, have the brake pads checked and any worn brake pads replaced.
A WARNING
Incorrect parking can cause serious Injuries.
• Never remove the vehicle key from the lg-nltlon lock when the vehicle Is In motion. The steering lock may be activated and you will no longer be able to steer or control the vehl-cl e.
A WARNING (Continued)
• Never park the vehicle where parts of the exhaust system can come into contact with inflammable material underneath the vehicle, e.g. undergrowth, leaves, dry grass, spilt fuel.
• Always apply the handbrake when the ve-hicle Is parked.
• Never leave children or people requiring assistance alone In the vehicle. They could release the handbrake, move the selector lev-er or gearshift lever and thus set the vehicle In motion. This can lead to accidents and se-rious injuries.
• Always take all vehicle keys with you ev-ery time you leave the vehicle. The engine can be started and electrical equipment such as the window controls can be used which could cause serious injury.
• Never leave children or people requiring assistance alone in the vehicle. They could become trapped in the vehicle in an emergen-cy and may not be able to get themselves to safety. For example, locked vehicles may be subjected to very high or very low tempera-tures, according to season. This can cause serious Injuries and illness or fatalities, espe-cially for small children.
CD
• To avoid unintentional movement when parking the vehicle, first apply the handbrake and then remove your foot from the brake ped-al.
• Always take care when driving in car parks with protruding kerbstones or bollards. Objects that protrude from the ground can damage the bumper and other components when parking the vehicle. In order to avoid any damage, stop the vehicle before the wheels can touch the bollards or kerbs.
• Drive carefully through dips in the road, over driveways, ramps, kerbstones and other objects. Low-lying vehicle components such as the bumper, spoiler and parts of the running gear, engine or exhaust system could be dam-aged.
