Fuel selector
Pressing button Y in the centre
console switches between petrol and
natural gas operation. The LED 1
status shows the current operating
mode.
1 off=natural gas
operation.1 illuminates=petrol operation.
As soon as the natural gas tanks are
empty, petrol operation is
automatically engaged. Control
indicator Y illuminates in the Driver
Information Centre 3 80 until the
ignition is switched off.
A slight loss of power and torque can be expected in petrol operation. You
must therefore adapt your driving style (e.g. during overtaking
manoeuvres) and vehicle loads (e.g.
towing loads) accordingly.
Every six months run the petrol tank
down until control indicator §
illuminates and then refuel. This is
necessary to maintain fuel quality as
well as system function necessary for
petrol operation.
Fill the tank completely at regular intervals to prevent corrosion in the
tank.
Refuelling
Fuel filler flap is located at left rear side of vehicle.9 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.
Release the fuel filler flap by pulling
the flap by hand.
Insert key into fuel filler cap and turn
anticlockwise to unlock.
To remove fuel filler cap, rotate
anticlockwise.

The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12 %.
The permitted trailer load applies up to the specified incline and up to an
altitude of 1000 metres above sea
level. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10 % for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than
8 %, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is specified on the identification plate
3 164.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.The maximum permissible vertical
coupling load (75 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum load,
especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.
Rear axle load The permissible axle loads (see
identification plate or vehicle
documents) must not be exceeded.

Fuses Data on the replacement fuse must
match the data on the defective fuse.
There are two fuse boxes in the
vehicle:
■ on the right of the engine compartment, next to the battery
■ behind a cover on the lower part of the instrument panel, on the driver's
side
Before replacing a fuse, turn off the
respective switch and the ignition.
A blown fuse can be recognised by its melted wire. Do not replace the fuse
until the cause of the fault has been
remedied.
Some functions are protected by
several fuses.
Fuses may also be inserted without existence of a function.

3. Connect the black lead to thenegative terminal of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block or an
engine mounting bolt. Connect as far away from the discharged
battery as possible, however at
least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump.
2. After 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of 1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Release the cap by carefully lifting
with a screwdriver. To prevent
damage, it is recommended to place
a cloth between the screwdriver and
the frame.
The towing eye is stowed with the vehicle tools 3 143.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
