Driving and operating211Caution
Use of fuel that does not comply toEN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Fuel for liquid gas
operation
Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under
its French name GPL (Gaz de Pétrole Liquéfié). LPG is also known as
Autogas.
LPG consists mainly of propane and
butane. The octane rating is between
105 and 115, depending on the
butane proportion. LPG is stored
liquid at around 5 - 10 bar pressure.
The boiling point depends on the
pressure and mixing ratio. At ambient pressure, it is between -42 °C (pure
propane) and -0.5 °C (pure butane).Caution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
Full 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 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.
260Vehicle careCaution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Note
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The current tyre pressures can be
shown in the Vehicle Information
Menu in the Driver Information Centre
(DIC).
The menu can be selected by the
buttons on the turn signal lever.
Press the MENU button to select the
Vehicle Information Menu X.
Turn the adjuster wheel to select the
tyre pressure monitoring system.
System status and pressure warnings
are displayed by a message with the
corresponding tyre flashing in the
Driver Information Centre.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 117.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 309.
Vehicle care261
If w flashes for 60-90 seconds and
then illuminates continuously, there is
a fault in the system. Consult a
workshop.
After inflating, driving may be
required to update the tyre pressure
values in the DIC. During this time w
may illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for getting low pressure. Check tyre pressure.
Vehicle messages 3 126.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A temporary spare wheel is not
equipped with pressure sensors. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator w illuminates. For
the further three wheels the system
remains operational.The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor: replace
valve core and sealing ring. For
clipped sensor: replace complete
valve stem.
Vehicle loading status
Adjust tyre pressure to load condition according to tyre information label or
tyre pressure chart 3 309, and select
the relevant setting in the menu Tire
Load in the DIC, Vehicle Information
Menu 3 119.
Select:
■ Light for comfort pressure up to
3 people
■ Eco for Eco pressure up to
3 people
■ Max for full loading
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new tyre/
wheel position after rotating the tyres
or exchanging the complete wheel set and if one or more TPMS sensors
were replaced. The TPMS sensor
Vehicle care263
Temperature dependencyTyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
The tyre pressure value displayed in
the DIC shows the actual tyre
pressure. Therefore it is important to
check tyre pressure with cold tyres.
Tread depth Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and
rear wheels periodically. Ensure that
the direction of rotation of the wheels
is the same as before.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and make other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination requirements must be used.
Vehicle care267
10. Set the rocker switch on thecompressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to 6 bar whilstthe sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is inflated.
13. The prescribed tyre pressure should be obtained within
10 minutes. Tyre pressure
3 309 . When the correct pressure
is obtained, switch off the
compressor.If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for 10 minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button over the pressure indicator.
Do not run the compressor longer than 10 minutes.
14. Detach the tyre repair kit. Push catch on bracket to remove
sealant bottle from bracket. Screw
the tyre inflation hose to the free
connection of the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit in
load compartment.
15. Remove any excess sealant using a cloth.
16. Take the label indicating maximum permitted speed from
the sealant bottle and affix in the
driver's field of view.
17. Continue driving immediately so that sealant is evenly distributedin the tyre. After driving approx.
10 km (but no more than
10 minutes), stop and check tyre
pressure. Screw compressor air
hose directly onto tyre valve and
compressor when doing this.
