Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Control indicator b 3 97.
Deactivation
ESC can be deactivated: hold b
depressed for approx. 5 seconds.
Control indicator n illuminates.
ESC is reactivated by pressing b
again. If the TC system was
previously disabled, both TC and
ESC are reactivated.
ESC is also reactivated the next time
the ignition is switched on.
Fault
If there is a fault in the system the
control indicator b illuminates
continuously and a message appears in the Driver Information Centre. The
system is not operational.
Have the cause of the fault remedied
by a workshop.Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds of approx. 20 to
120 mph. Deviations from the stored
speeds may occur when driving uphill or downhill.
For safety reasons the cruise control
cannot be activated until the foot
brake has been operated once.
Activating in first gear is not possible.

Driving and operating155Resume stored speed
Turn thumb wheel to RES/+ at a
speed above 20 mph. The stored
speed will be obtained.
Switching off
Press rocker switch m at the lower
end, control indicator m extinguishes.
The stored speed is deleted.
Switching off the ignition also deletes
the stored speed.
Parking assist9 Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area when driving backwards or
forwards while using parking
assist system.
The parking assist makes parking easier by measuring the distance
between the vehicle and obstacles,
and giving acoustic signals.
The system consists of four ultrasonic parking sensors in the rear bumper. If
the vehicle is equipped with a front
parking assist, the system consists of
four additional ultrasonic parking
sensors in the front bumper.
Control indicator r 3 96.
Operation
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.
The front parking assist can also be activated at a speed up to 7 mph with
a brief press of the parking assist
button.
If r is pressed once within an
ignition cycle, the front parking assist
is deactivated at a speed above
7 mph. It will be reactivated if vehicle
speed has not exceeded 16 mph

160Driving and operatingFull function of the LPG system can
only be guaranteed with liquid gas
which complies with the minimum
requirements of DIN EN 589.
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
around 60 seconds (depending on
exterior temperature) and the first firm
press on the accelerator. The LED
1 status shows the current operating
mode.1 off:petrol operation1 flashes:checking conditions
for fuel transition to
liquid gas operation.
Illuminates if
conditions are fulfilled.1 illumi‐
nates:liquid gas operation1 flashes
five times
and extin‐
guishes:liquid gas tank is
empty or failure in
liquid gas system. A
message is displayed
in the Driver
Information Centre.
If the fuel tank is empty, the engine
will not start.
The selected fuel mode is stored and
reactivated at the next ignition cycle if
conditions allow.
As soon as the liquid gas tanks are empty, petrol operation is
automatically engaged until the
ignition is switched off.
When switching automatically
between petrol or gas operation, a
brief delay of engine tractive power
may be noticeable.
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.
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 liquid gas mode.
Page 163 of 251

Driving and operating161In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are not
fulfilled. 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.
Notice
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
ignition and any external heaters
with combustion chambers.
Follow the operating and safety
instructions of the filling station
when refuelling.

162Driving and operating9Danger
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 fuel filler flap can only be opened
if the vehicle is unlocked. Pull flap at
the recess and open.
To open, turn the cap slowly
anticlockwise.
The fuel filler cap can be retained in
the bracket on the fuel filler flap.
For refuelling, fully insert the pump
nozzle and switch it on.
After automatic cut-off, it can be
topped up by operating the pump
nozzle maximally two more times.Caution
Wipe off any overflowing fuel
immediately.
To close, turn the fuel filler cap
clockwise until it clicks.
Close the flap and let engage.
Fuel filler cap
Only use genuine fuel filler caps. Diesel-engined vehicles have special
fuel filler caps.
Liquid gas refuelling Follow the operating and safety
instructions of the filling station when
refuelling.
The filling valve for the liquid gas is
behind the fuel filler cap.

176Vehicle care
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.
Only use high-performance brake
fluid approved for the vehicle.
Brake and clutch fluid 3 220.
Vehicle 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
four weeks can lead to 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.
The anti-theft alarm siren must be
deactivated as follows: Switch the
ignition on then off, disconnect the
vehicle's battery within 15 seconds.

Replacing the vehicle battery
Notice
Any deviation from the instructions
given in this paragraph may lead to
a temporary deactivation of the stop-
start system.
When the vehicle battery is being
replaced, please ensure that there
are no open ventilation holes in the
vicinity of the positive terminal. If a
ventilation hole is open in this area, it
must be closed off with a dummy cap, and the ventilation in the vicinity of the
negative terminal must be opened.
Only use vehicle batteries that allow
the fuse box to be mounted above the vehicle battery.
In vehicles with an AGM (Absorptive
Glass Mat) battery, make sure to
have the battery replaced with
another AGM battery.
