WARNING
LPG is a highly explosive and inflammable substance. It may cause se-
vere burns and other injury.
● Due care must be taken to avoid any risk of fire or explosion.
● When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a leak.
Note
● If frequent short journeys are made, especially when the outside tem-
perature is low, the vehicle will tend to run on petrol more often than on
LPG. Therefore, the petrol tank may empty before the LPG tank.
● The notification LPG mode not possible may be displayed.

–
The vehicle should be stationary with the engine idling. Press
the clutch down thoroughly.
– Place the gear lever into neutral and push the lever downwards.
– Slide the gear lever to the left, and then into the reverse posi-
tion shown on the gear lever.
The reverse gear can only be engaged when the vehicle is stationary. When
the engine is running and before engaging this gear, wait about 6 seconds
with the clutch pressed down thoroughly in order to protect the gearbox.
The reverse lights light up when the reverse gear is selected and the igni-
tion is on.
WARNING
● When the engine is running, the vehicle will start to move as soon as
a gear is engaged and the clutch released.
● Never select the reverse gear when the vehicle is in motion. Risk of
accident.
Note
● Do not rest your hand on the gear lever while driving. The pressure of
your hand could cause premature wear on the selector forks in the gearbox.
● When changing gear, you should always depress the clutch fully to
avoid unnecessary wear and damage.
● Do not hold the car “on the clutch” on hills. This causes premature wear
and damage to the clutch.
● Do not leave your foot on the clutch pedal; although the pressure may
seem insignificant, it can cause the premature wear of the clutch plate. Use
the foot rest when you do not need to change gear. 

speeds to use the full power of the engine. This programme is not
recommended for use on 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 steer-
ing wheel controls when this option is fitted ⇒ page 171.
Selector lever locking
The selector lever lock prevents gears from being engaged
inadvertently, which would cause the vehicle to move.
Fig. 125 Deactivating
the lock
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 posi-
tion 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.

–Press the button on the selector lever knob (on the left)
⇒ fig. 126.
– Select a gear for driving ( R, D or S).
– Release the button and wait a few seconds for the gear to en-
gage, a light jerk will be felt.
– Release the brake and accelerate.
Short stop
– Hold the vehicle stationary with the brake pressed down (for ex-
ample 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 (en-
gine 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 used on a very steep gradient, the en-
gine braking is insufficient and 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 lev-
er to position 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 vehi-
cle 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 tip-
tronic programme to select a lower gear.
● If you must stop on a hill, always hold the vehicle using the footbrake
to avoid rolling back. 

Driving
WARNING (Continued)
● 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 re-
duction 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 lev-
er 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 dam-
age. 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 lubri-
cated. Changing gear in tiptronic mode*

ing mode regardless of the pre-selected driving mode.
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 permit-
ted 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 ⇒ 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
+ OFF
towards the steering wheel for ap-
proximately one second. You will also leave tiptronic mode if the paddle lev-
ers 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 engine 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.
