the motorway or in the city.
Selecting the manual programme (tiptronic)
This programme allows driving similar to a manual gearbox.
This programme may be accessed using the selector lever or from the
steering wheel controls when this option is fitted ⇒page 174.Selector lever locking
The selector lever lock prevents gears from being engaged
inadvertently, which would cause the vehicle to move.Releasing the selector lever lock
–Start the vehicle. – Press and release the brake pedal, at the same time press the
button on the selector lever.
The lock is only activated when the vehicle is stopped or at a speed of less
than 5 km/h. At higher speeds, the lock is automatically released in position
N.
For rapid changes of position (e.g. from R to D) the lever will not lock. If the
lever remains in the position N more than one second then it is locked. With
the automatic lock, the lever is prevented passing from P and N to any other
gear without first pressing the brake pedal.
The selector lever must be put in the position P in order to remove the key.Driving with an automatic gearbox* / DSG automatic gearbox*
The drive and reverse gears are automatically engaged.

Driving
– Press and hold the foot brake.
– Press the button on the selector lever knob (on the left)
⇒page 172, fig. 126 .
– Select a gear for driving ( R, D or S).
– Release the button and wait a few seconds for the gear to engage, a light jerk will be felt.
– Release the brake and accelerate.
Short stop
– Hold the vehicle stationary with the brake pressed down (for example at traffic lights). The selector lever does not need to be
put into the positions P or N for this.
– Do not press the accelerator.
Parking the vehicle
– Press the brake pedal and hold to bring the vehicle to a stop.
– Apply the handbrake firmly.
– Press in the button on the selector lever knob, move the lever to the position P and release the button.
Driving slowly
– Move the selector lever to position D and press to the right to put
the lever into tiptronic mode.
– Press the gear lever towards (-) to select a lower gear. Hill stop
– Hold the vehicle, in all cases, using the brake pedal to prevent
rolling back.
– Do not try to slow the vehicle using another forward gear (engine braking).
Descending gradients
– With the gear engaged, release the brake and accelerate.
The steeper the gradient the lower the gear must be for effective engine
braking. For example, if 3rd gear is us ed on a very steep gradient, the engine
braking is insufficient and the vehicle accelerates. So that the engine speed
does not become excessive, the gearbox changes to the next highest gear.
Depress the brake pedal and move the selector lever to the tiptronic gate to
return to 3rd gear.
WARNING
•The driver should never leave the vehicle while the engine is running or
with any gear selected. If for any reason you must leave the vehicle with the
engine running, apply the handbrake and move the selector lever to posi-
tion P.•When the engine is running and the positions D, S or R are selected, it
is necessary to hold the vehicle with the brake pedal because the vehicle
will creep at a low speed.•Never accelerate while changing the position of the gear lever (risk of
an accident).•The gear lever must never be moved into the positions R or P while
moving (risk of an accident).•Before descending a steep gradient, reduce speed and use the tiptronic
programme to select a lower gear.

Driving
174•If you must stop on a hill, always hold the vehicle using the footbrake
to avoid rolling back.•The footbrake must not be held for a long period of time, not even
lightly; continuous braking will cause overheating of the brakes and a
reduction or even a loss of braking power and a significant increase in
braking distances.•Never allow the vehicle to coast down a gradient with the selector lever
in positions N or D, even when the engine is not running. For descents, the
use of the tiptronic programme is recommended to keep the speed
reduced.Caution
•Never use the automatic gearbox to hold the vehicle stationary on a hill,
even for short periods, as this may overheat the gearbox and cause damage.
Apply the handbrake or depress the foot brake to hold the vehicle in position.•If the vehicle is allowed to roll with the engine stopped but the selector in
position N then the gearbox may be damaged because it will not be
lubricated.

General information about driving in tiptronic mode
When accelerating, the automatic gearbox / DSG automatic gearbox goes
into a higher gear a little before the engine reaches its maximum permitted
revolutions.
If a lower gear is selected, the automatic gearbox / DSG automatic gearbox
will only change down when the engine cannot go over its maximum
permitted revolutions.
If tiptronic is selected whilst the vehicle is in motion and the automatic
gearbox / DSG automatic gearbox is in third gear and selector lever position
D, tiptronic mode will then also be in third gear. Changing gears in the normal or sport programme using the steering wheel
paddle levers
If the paddle levers ⇒
page 174, fig. 128 are used in the normal or sport
programme, the system switches temporarily to tiptronic mode. To exit
tiptronic mode again, press the right paddle lever towards the steering
wheel for approximately one second. You will also leave tiptronic mode if the
paddle levers are not moved for a certain time.
Note
•The gearbox controls on the steering wheel can operate with the selector
lever in any position and with the vehicle in motion.Kickdown feature
This feature allows maximum acceleration.If you press the accelerator down thoroughly, the gearbox automatically
changes down, depending on speed and e ngine speed, into a lower gear to
take full advantage of give the vehicle maximum acceleration.
The gearbox does not change gear until the engine reaches the maximum
determined engine speed for the gear.
WARNING
You could lose control of the vehicle if you accelerate on slippery road
surfaces. Risk of serious injury.•Be particularly careful when using the kickdown features on slippery
road surfaces. With a fast acceleration, the vehicle could lose traction and
skid.•You should use the kickdown feature only when traffic and weather
conditions allow it to be used safely.
