Driving and operating187Parking assist9Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area when driving backwards or
forwards while using parking
assist system.
Front-rear parking assist
The front-rear parking assist
measures the distance between the vehicle and obstacles in front and
behind the vehicle. The system gives acoustic signals and display
messages.
The system has four ultrasonic
parking sensors each in the rear and front bumper.
It uses two different acoustic warning
signals for the front and rear
monitoring areas, each with a
different tone frequency.
Activation
When reverse gear is engaged, the
front and rear parking assist is ready
to operate.
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
When driving forward at low speeds,
the front parking assist can also be
activated by pressing the parking
assist button r.
Once the button r is pressed within
an ignition cycle, the front parking
assist is always reactivated when the vehicle underruns a certain value.
Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles in front of or
behind the vehicle. An obstacle
detection is indicated by beeps
sounding respective from the front or
rear of the vehicle. The intervall
between the beeps becomes shorter
as the vehicle gets closer to the
obstacle. when the distance is less
than 30 cm, a continuous tone
sounds.

190Driving and operating
A successful parking manoeuvre is
indicated by a confirmation symbol.
Always pay attention to the sound of
the front-rear parking assist.
Continuous sound means that the
distance to an obstacle is less than approx. 30 cm.
Changing the parking side
The system is configured to detect
parking slots on the passenger side.
To detect parking slots on the driver
side, press button ( for approx.
2 seconds.
Display priorities
After activating the advanced parking assist, a message appears in the
Driver Information Centre. Advanced
parking assist indication in the Driver
Information Centre can be inhibited
by vehicle messages with a higher
priority. After approving the message
by pressing the SET/CLR button on
the turn signal lever or the 9 button
in the steering wheel controls,
advanced parking assist instructions
appear again and the parking
manoeuvre can be continued.
Deactivation
The system is deactivated by:
■ pressing the ( button
■ parking manoeuvre successfully ended
■ driving faster than 30 km/h
■ switching off the ignition
Deactivation by the driver or by the system during manoeuvring will beindicated by Parking Deactivated in
the Driver Information Centre.Fault
A message appears in the Driver
Information Centre when:
■ there is a fault in the system
■ the driver did not successfully complete the parking manoeuvre
■ the system is not operational
If an object is detected during parking instructions, Stop is indicated in the
Driver Information Centre. Removing
the object will resume the parking
manoeuvre. If the object is not
removed, the system will be

204Driving and operating
Press the LPG button to switch
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 around 60 seconds (depending
on exterior temperature) and the first
firm press on the accelerator. The
LED status shows the current
operating mode.1 off=petrol operation1 illumi‐
nates=liquid gas operation1 flashes=no switching is
possible, one type
of fuel is empty
As soon as the liquid gas tank is
empty, petrol operation is
automatically engaged until the
ignition is switched off.
Every six months, run the petrol tank
down until control indicator i or Y
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.
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 not
fulfilled.
Seek the assistance of a workshop in the event of all other faults.Caution
Repairs and adjustments may onlybe 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 the gas odour persists, do not start
the engine. 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.

Driving and operating205
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 and lights. Close the
manual shut-off valve on multivalve.
Refuelling9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
Caution
In case of misfuelling, do not
switch on ignition.
Fuel filler flap is located at right rear
side of vehicle.

The brake fluid level must be betweenthe MIN and the MAX marks.
When topping up, ensure maximum cleanliness as contamination of the
brake fluid can lead to brake system
malfunctions. Have the cause of the
loss of brake fluid remedied by a
workshop.

Vehicle battery
Vehicles without stop-start system
will be equipped with a lead acid
battery. Vehicles with stop-start
system will be equipped with an AGM battery which is not a lead acid
battery.
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
4 weeks can lead to vehicle battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
Battery discharge protection 3 132.
Replacing the vehicle battery Note
Any deviation from the instructions
given in this paragraph may lead to
a temporary deactivation of the stop-
start system.
