Manual gearbox: selecting a gear
®
Never switch off the engine or the ignition while the vehicle is in motion. This can lead to a
loss of vehicle control, accidents and serious injuries.
•The airbags and belt tensioners will not work if the ignition is switched off.
•The brake servo will not work when the engine is switched off. That is why more
pressure on the brake pedal is needed to brake the vehicle when the engine is
switched off.
•The power steering will not work when the engine is not running. More power is
needed to steer the vehicle when the engine is switched off.
•When the ignition is switched off, the steering lock may activate and you will no longer
be able to steer the vehicle.
•The start/stop system must be deactivated if work is to be carried out in the engine
compartment.
WARNING
If the start/stop system is used in very high outside temperatures over a long period, the
12-volt vehicle battery can be damaged.

the gearbox could occur if at high speeds or high engine revs one or more gears are skipped when
shifting down gear, even if the clutch is not released when doing this ⇒.
Kickdown
On vehicles with speed limiter ⇒ Speed limiter, the kickdown function allows the stored speed limit
to be intentionally exceeded, e.g. when overtaking.
When the accelerator is fully depressed, the speed limiter regulator is temporarily switched off when
the vehicle exceeds the stored speed.
Once the vehicle returns to a speed below the stored speed and the accelerator is no longer fully
depressed, speed limiter regulation becomes active again.
When the Eco driving profile is selected in vehicles with driving profile selection ⇒ Driving profile
selection and 4MOTION Active Control and the accelerator is depressed fully beyond the pressure
point, the engine output is automatically regulated to ensure maximum vehicle acceleration.
Troubleshooting
Clutch does not transmit the entire engine torque. If necessary, remove foot from clutch pedal.
The clutch can overheat, for example if the vehicle pulls off regularly, travels at a crawl for long
periods, or in stop and go traffic. Overheating is indicated by the warning lamp and in some cases
by additional warning lamps and a text message in the instrument cluster display. An acoustic
warning may also be given ⇒.Clutch is defective. Drive on carefully! Seek expert
assistance. Failure to do so could result in considerable damage to the clutch.
When the engine is running, the vehicle will start to move as soon as a gear is engaged
and the clutch released. This also applies when the electronic park brake has been
switched on.
•Never engage reverse gear while the vehicle is in motion.
WARNING
Shifting gears incorrectly to a lower gear can lead to a loss of control of the vehicle, which
can cause accidents and serious injuries.

DSG dual clutch gearbox
Function of the DSG dual clutch gearbox
Description
The vehicle is equipped with a DSG dual clutch gearbox.
The DSG dual clutch gearbox is a gearbox which uses dual-clutch technology to change gear
automatically. It uses a dual clutch and two gear train halves 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 comfort and convenience of a conventional automatic transmission.
Function
When driving, engine power is transferred to the drive axle 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 gear train halves, the engine power is always
connected to one gear train half when driving. Before a gear change, the next higher or lower gear
is already preselected in the load-free second gear train half. 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.
Thanks to its design, the DSG dual clutch gearbox is more efficient than an automatic gearbox.
Whereas in an automatic gearbox the torque converter is constantly in use, in the DSG dual clutch
system the clutch can be opened at idling speed, thus saving fuel. Thanks to its efficiency, low
weight and intelligent control system, the DSG dual clutch system usually enables fuel
consumption equal to or lower than a manual gearbox.
However, just like the manual gearbox, the clutch in the DSG dual clutch gearbox is subject to
wear. Regular maintenance is necessary depending on the type of dual clutch gearbox DSG;
further information ⇒ Scope of service. In the event of a fault in one gear train half, the DSG dual
clutch gearbox also allows one gear train half to be deactivated and the journey to be continued
using the other gear train half ⇒ Troubleshooting. If this happens, have the system checked as
soon as possible by a qualified workshop.

Instrument cluster display
Serious damage to the clutch and gearbox can occur if the gear stick on the manual
gearbox is shifted to too low a gear when travelling at high speeds or at high revs. This
also applies if the clutch remains depressed and the gears do not engage.
NOTICE
Please note the following to help avoid damage and premature wear:
•Do not rest your hand on the gear lever when driving. The pressure from your hand is
passed onto the selector forks in the gearbox.
•Ensure that the vehicle has come to a full stop before engaging reverse gear.
•Always fully depress the clutch pedal when changing gear.
•Do not hold the vehicle by riding the clutch on a hill with the engine running.

– Standard forward driving position
Position : Normal programme.
All forward gears are shifted up and down automatically. The timing of the gear shift is determined
by the engine load, your individual driving style and the speed of the vehicle.
Position : Sport programme.
The forward gears are automatically changed up later and down earlier than in selector lever
position D. This exploits the engine’s full power. The timing of the gear shift is determined by the
engine load, your individual driving style and the speed of the vehicle.
– Changing driving modes
The change between positions D and S is carried out by tapping the selector lever once to the rear
out of selector lever position D/S⇒ Fig. 123. The selector lever will always return to selector lever
position D/S.
Using this function it is possible to access the Tiptronic option from both the Sport programme S
and from the Normal programme D⇒ Changing gear using Tiptronic.
Selector lever lock
The selector lever lock in selector lever position P or N prevents gears from being engaged
unintentionally, which would cause the vehicle to move.
To release the selector lever lock, switch on the ignition and press the brake pedal. Then press the
lock button in the selector lever handle in the direction of the arrow ⇒ Fig. 123.
The selector lever lock is not engaged if the selector lever is moved quickly through position N, e.g.
when shifting from reverse to D/S. 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 mphyf .

Emergency programme
There is a fault in the system if all the displays on the instrument cluster for the selector lever
positions have a light background. The DSG dual clutch gearbox is running in an emergency
programme. The vehicle can still be driven in the emergency programme, 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.
In all cases you should have the DSG dual clutch gearbox checked by a qualified workshop
immediately.
Overheating of the DSG dual clutch gearbox
The DSG dual clutch gearbox can become too hot, for example, if the vehicle pulls off
frequently, drives at crawling speed for long periods, or in stop-and-go traffic. Overheating is
indicated by the warning lamp 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 does not move forwards or backwards even though a position
has been selected
If the vehicle will not move in the required direction, the system may have selected the position
incorrectly. Depress the brake pedal and reselect the position.
If the vehicle still does not move in the required direction, there is a system fault. Seek expert
assistance and have the system checked.
Downhill speed control
If the vehicle is being held on the Auto Hold function, the green indicator lamp lights up.
Switch off Auto Hold if necessary ⇒ Auto Hold function.
The Hill Descent Control system in vehicles with a DSG dual clutch gearbox helps when braking
and travelling downhill ⇒. This system uses the braking power of the engine, rather than the
brakes directly.
The DSG dual clutch gearbox selects the best gear for the circumstances, depending on the
steepness of the hill and the current speed. The selector lever must be in position D/S. The downhill
speed control is not active in Tiptronic mode.
As the downhill speed control system can shift down only as far as third gear, it may be necessary
to activate the Tiptronic mode when driving down particularly steep inclines. When in Tiptronic
mode, select second or first gear manually in order to make use of the braking effect of the engine
and to relieve the load on the brakes.
The start/stop system is automatically deactivated as long as downhill speed control is active.
Activating downhill speed control automatically:
•If the downhill gradient is greater than approximately 6yb .
•AND: if the selector lever is in position D/S.

Never move the selector lever out of the position P if the electronic parking brake is not
switched on. Otherwise the vehicle could move unexpectedly if it is stopped on an incline,
which could lead to accidents and serious injuries.

•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 km/h (12 mphyf .
•If the text message and signal tone are repeated every ten seconds, the vehicle must be
parked safely immediately and the engine switched off. 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.
