Instruments and controls

If the natural gas tanks are not
refuelled, the system must be
manually switched to petrol operation
before the engine is started up again.
This will prevent damage to the
catalytic converter (overheating
caused by irregular fuel supply).
If the selector switch is operated
several times within a short time
a switchover block is activated. The
engine remains in the current
operating mode. The block remains
active 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 Y
illuminates and 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. Service display
The message InSP appears when it
is time for servicing. Further
information

Control indicators
The control indicators described are
not present in all vehicles. The
description applies to all instrument
versions. When the ignition is
switched on, most control indicators
will
illuminate briefly as a functionality
test. The control indicator colours mean:
Red = Danger, important
reminder,
Yellow = Warning, information, fault,
Green = Confirmation of activation,
Blue = Confirmation of activation.

Driving and operating
The system can also be activated at
low speed by pressing the r button.
An obstacle is indicated by buzzers.
The interval between the buzzers
becomes shorter as the vehicle gets
closer to the obstacle. When the
distance is less than 30 cm, the
buzzer is continuous. 9
Warning Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external
noise sources may cause
the system to fail to detect
obstacles. Deactivation
Deactivate the system by pressing
the r button.
The system automatically switches
itself off when the vehicle is driven
above a certain speed.
Towing equipment
The system automatically considers
a factory-fitted towing equipment. The rear parking sensors are
deactivated when towing.
Fuel
Fuel for petrol engines
Only
use unleaded fuel that complies
with DIN EN 228.
Fuels with ethanol content greater
than 5% may only be used if the
vehicle has been specifically
developed and approved for these
fuels.
Use fuel with the recommended
octane rating 3 209. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly
increases fuel consumption. Caution
Use of fuel with too low an octane
rating could lead to uncontrolled
combustion and engine damage.
Fuel for diesel engines
Only use diesel fuel that complies
with
DIN EN 590. The fuel must have
low sulphur content (max. 50 ppm).

3. Ensure the jack is positioned correctly with the vehicle jacking
points. 4. Set the jack to the necessary
height before positioning it directly
below the jacking point in
a manner that prevents it from
slipping. Attach jack handle and with the
jack correctly aligned rotate
handle until wheel is clear of the
ground.
5.
Unscrew the wheel bolts.
6. Change the wheel.
7. Screw in the wheel bolts.
8. Lower vehicle.
9. Install the wheel wrench ensuring that it locates securely and tighten
each bolt in a crosswise
sequence. Tightening torque is
110 Nm.
10. Align the valve hole in the wheel cover with the tyre valve before
installing. Install wheel bolt caps.
11.
Stow the replaced wheel 3 179
and the vehicle tools 3 173.
12. Check the tyre pressure of the installed tyre and also the wheel
bolt torque as soon as possible.
Have the defective tyre renewed or
repaired.
Spare wheel
The spare wheel can be classified as
a temporary spare wheel depending
on the size compared to the other
mounted wheels and country
regulations.
The spare wheel has a steel rim.
Use of a spare wheel that is smaller
than the other wheels or together with
winter tyres could affect driveability.
Have the defective tyre replaced as
soon as possible.
