Starting off
Check before starting off ● Tyre pressure and condition 3 231, 3 270.
● Engine oil level and fluid levels 3 203.
● All windows, mirrors, exterior lighting and number plates are
free from dirt, snow and ice and
are operational.
● Proper position of mirrors, seats, and seat belts 3 31, 3 41,
3 49.
● Brake function at low speed, particularly if the brakes are wet.

Keys, doors and windows31A triggered alarm, which has not been
interrupted by the driver, will be
indicated by the hazard warning
lights. They will flash quickly three
times the next time the vehicle is
unlocked with the radio remote
control. Additionally, a warning
message or a warning code is
displayed in the Driver Information Centre after switching on the ignition.
Vehicle messages 3 100.
If the vehicle's battery is to be
disconnected (e.g. for maintenance
work), the alarm siren must be
deactivated as follows: Switch the
ignition on then off, then disconnect
the vehicle's battery within
15 seconds.
Immobiliser The system is part of the ignition
switch and checks whether the
vehicle is allowed to be started with the key being used.
The immobiliser is activated
automatically after the key has been removed from the ignition switch.If the control indicator d flashes when
the ignition is on, there is a fault in the
system; the engine cannot be started. Switch off the ignition and repeat the
start attempt.
If the control indicator continues
flashing, attempt to start the engine
using the spare key and seek the
assistance of a workshop.
Note
The immobiliser does not lock the
doors. You should always lock the
vehicle after leaving it and switch on the anti-theft alarm system 3 24,
3 29.
Control indicator d 3 93.Exterior mirrors
Convex shape The shape of the mirror makes
objects appear smaller, which will
affect the ability to estimate
distances.
Side blind spot alert 3 183.
Electric adjustment
Select the relevant exterior mirror by
turning the control to left (L) or right
(R) . Then swivel the control to adjust
the mirror.
In position 0 no mirror is selected.

82Instruments and controlsFuel gauge
Displays the fuel level or gas level in
the tank depending on the operation
mode.
Control indicator i illuminates if the
level in the tank is low. Refuel
immediately if it flashes.
During liquid gas operation, the
system automatically switches over to
petrol operation when gas tanks are
empty 3 82.
Never run the tank dry.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified tank capacity.
Fuel selector
Pressing LPG switches between
petrol and liquid gas operation as
soon as the required parameters (coolant temperature, gas
temperature and minimum engine
speed) have been reached. The
requirements are usually fulfilled after
approximately 60 seconds
(depending on exterior temperature)
and the first firm press on the
accelerator. The LED status shows
the current operating mode when
egnine is running.
LED off:petrol operationLED
flashes:checking conditions for
fuel transition to liquid
gas operation.
Illuminates if conditions
are fulfilled.LED illu‐
minates:liquid gas operationLED
flashes
rapidly:liquid gas tank is empty
or failure in liquid gas
system. A message is
displayed in the Driver
Information Centre.
The selected fuel mode is stored and reactivated at the next ignition cycle if
conditions allow.
As soon as the liquid gas tank gets
empty a warning message is
displayed in the Driver Information
Centre and the LED in the button
flashes rapidly.
When the liquid gas tank is empty,
petrol operation is automatically
engaged.
When switching automatically
between petrol or gas operation, a
brief delay of engine tractive power
may be noticeable.

Instruments and controls83When petrol fuel tank is empty, the
engine will not start.
Every six months, run the petrol tank
down until control indicator i
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
Fill the tank completely at regular intervals to prevent corrosion in the
tank.
Fuel for liquid gas operation 3 191.
Faults and remedies
If gas mode is not possible, check the following:
● Is there enough liquid gas present?
● Is there enough petrol present for
starting?
Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to gas mode.
In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are notfulfilled. If conditions allow, it might be possible to manually switch back to
liquid gas operation.
Seek the assistance of a workshop in
the event of all other faults.Caution
Repairs and adjustments may only be made by trained specialists in
order to maintain the safety and
warranty on the LPG system.
Liquid gas is given a particular odour
(odorised) so that any leaks can be
detected easily.
9 Warning
If you smell gas in the vehicle or in
the immediate vicinity, switch to petrol mode immediately. No
smoking. No naked flames or
ignition sources.
If possible, close the manual shut-off
valve on the multivalve. The
multivalve is located on the liquid gas
tank in the load compartment,
underneath the rear floor cover.
Turn the thumb wheel clockwise.
If no further gas odour is perceptible
when the manual shut-off valve is
closed, the vehicle can be used in
petrol mode. If the gas odour persists, do not start the engine. Have the
cause of the fault remedied by a
workshop.
When using underground car parks,
follow the instructions of the operator
and local laws.
Note
In the event of an accident, switch off
the ignition. Close the manual shut-
off valve on multivalve.

conditions, the interval at which an
engine oil and filter change will be
indicated can vary considerably.
To display the remaining engine oil

9 Warning
When the engine is off,
considerably more force is needed
to brake and steer. During an
Autostop the brake servo unit will still be operational.
Do not remove key until vehicle is stationary, otherwise the steeringwheel lock could engage
unexpectedly.
Check oil level before seeking the
assistance of a workshop 3 203.

Driving and operating143Automatic Starter ControlThis function controls the engine
starting procedure. The driver does
not need to hold the key in position 3.
Once applied, the system will go on starting automatically until the engine is running. Because of the checkingprocedure, the engine starts running
after a short delay.
Possible reasons for a non-starting
engine:
● Clutch pedal not operated (manual transmission).
● Brake pedal not operated or selector lever not in P or N
(automatic transmission).
● Timeout occurred.
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully protect the engine.Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It starts the engine
automatically as soon as the clutch is
depressed. A battery sensor ensures
that an Autostop is only performed if
the vehicle battery is sufficiently
charged for a restart.
Activation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.Deactivation
Deactivate the stop-start system
manually by pressing eco. The
deactivation is indicated when the
LED in the button extinguishes.
Autostop If the vehicle is at a low speed or at a
standstill, activate an Autostop as
follows:
● Depress the clutch pedal.
● Move the selector lever to neutral.
● Release the clutch pedal.
