LPG quality and consumption
Quality requirements for LPG are regulated for all Europe in DIN EN 589 and
permit the use of LPG throughout Europe without any problems.
LPG is a mixture of propane and butane. 
Safety FirstOperating instructionsPractical TipsTechnical Specifications

178Driving
A difference is drawn between winter gas and summer gas. Winter gas has a
higher proportion of propane gas. As a result, the driving range of winter
gas may be lower (due to increased consumption) than that of summer gas.
The vehicle's engine management adapts automatically to the LPG used.
Therefore, both types of LPG can be mixed in the tank, without the need for
comprehensive draining before applying a different quality LPG.
LPG and safety
If you can smell gas or suspect that there is a leak in the LPG system. ⇒ 
●Stop the vehicle immediately.
● Switch the ignition off.
● Open the doors to appropriately ventilate the vehicle.
● Extinguish cigarettes immediately.
● Move away from the vehicle or switch off objects that may cause sparks
or a fire.
● If you continue to smell gas, do not continue driving!
● Seek specialist assistance. Have the fault repaired.
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.
WARNING
Failure to act when you can smell gas in the vehicle or when refuelling
can cause serious injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services.
Note
● The LPG system must be subject to regular inspections at a specialised
workshop in accordance with the Maintenance Plan.
● The engine is always started with petrol, even when LPG was being used
when it was switched off. For this reason the tank should never be drained
of petrol completely.
● 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.
● If while you were driving the system switched automatically to petrol op-
erating mode because the LPG tank was almost empty, the next few times
the engine starts up, and according to the outside temperature and and
driving style, it may switch briefly to LPG operating mode to use up what is
left in the tank.
● When the system switches automatically to petrol operating mode be-
cause the LPG tank is almost empty, you can revert to gas operating mode
by pressing the button ⇒ Fig. 141 GAS
while driving slowly and with low ac-
celeration. This procedure can be repeated several times while driving with
precaution until all the LPG left in the tank has been used up.
● Vehicles that can display information or warning messages on the dash-
board may show information related to LPG.
● The notification LPG mode not possible may be displayed.

– Place the gearbox lever into neutral and push the lever down-
wards.
– Slide the gearbox lever to the left, and then into the reverse po-
sition shown on the 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 switch on 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 vehicle “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. 

mended 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 186.
Selector lever locking
The selector lever lock prevents gears from being engaged
inadvertently, which would cause the vehicle to move.
Fig. 148 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. Level lock can only be engaged with the vehicle stationary at a speed of less
than 5 km/h (3 mph). It is automatically switched off at higher speeds 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 automatic gearbox/DSG automatic gearbox*
The drive and reverse gears are automatically engaged.

Driving
– 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
– 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. 
