Extend the key and open the unit.
Replace the battery (battery type
CR 2032), paying attention to the installation position. Close the unit
and synchronise.
Key with fixed key section
Have the battery replaced by a
workshop.
Radio remote control
synchronisation
After replacing the battery, unlock the
door with the key in the driver's door
lock. The radio remote control will be
synchronised when the ignition is switched on.
Memorised settings Whenever the key is removed from
the ignition switch, the following
settings are automatically memorised by the key:
■ Lighting
■ Infotainment system (only CD 400)
■ Central locking system
■ Comfort settingsThe saved settings are automatically used the next time the memorised key
is inserted into the ignition switch and
turned to position 1 3 133.
A precondition is that Personalization
by driver is activated in the personal
settings of the Graphic-Info-Display.
This must be set for each key used.
On vehicles equipped with
Colour-Info-Display, the
personalisation is permanently
activated.
Vehicle personalisation 3 109.
Central locking system Unlocks and locks doors, load
compartment and fuel filler flap.
A pull on an interior door handle
unlocks the respective door. Pulling the handle once more opens the door.
Notice
In the event of an accident in which
airbags or belt pretensioners are
deployed, the vehicle is
automatically unlocked.Unlocking
Press button c.
Two settings are selectable: ■ To unlock only the driver's door and
the fuel filler flap, press button c
once. To unlock all doors and the

Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified tank capacity.

Service display
The engine oil life system lets you
know when to change the engine oil
and filter. Based on driving
conditions, the interval at which an
engine oil and filter change will be
indicated can vary considerably.

154Driving and operating
Pressing the LPG button 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 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 tanks are
empty, petrol operation is
automatically engaged until the
ignition is switched off.
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.
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 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.

Accessories and vehicle
modifications
We recommend the use of genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or
guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
If the vehicle is to be stored for several months:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve the rubber seals.
■ Fill up fuel tank completely.
■ Change the engine oil.
■ Drain the washer fluid reservoir.
■ Check the coolant antifreeze and corrosion protection.
■ Adjust tyre pressure to the value specified for full load.
■ Park the vehicle in a dry, well ventilated place. Engage first orreverse gear or set selector lever to P . Prevent the vehicle from rolling.
■ Do not apply the parking brake.

Vehicle care189Wheels and tyresTyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb
when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Winter tyres Winter tyres improve driving safety attemperatures below 7 °C and should
therefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.Tyre designations
E.g. 195/65 R 15 91 H195=Tyre width, mm65=Cross-section ratio (tyre
height to tyre width), %R=Belt type: RadialRF=Type: RunFlat15=Wheel diameter, inches91=Load index e.g. 91 is
equivalent to 615 kgH=Speed code letter
Speed code letter:
Q=up to 100 mphS=up to 112 mphT=up to 118 mphH=up to 130 mphV=up to 150 mphW=up to 168 mph
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre deflation detection system or
tyre pressure monitoring system.
Unscrew the valve cap.
Tyre pressure 3 224 and on the label
at the front passenger door.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
