FuelVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Fuel quality
Fuels that are marked on the gas pump as con‐
taining metal must not be used.
Refuel only with unleaded gasoline with‐
out metallic additives.
Do not refuel with any leaded gasoline or gaso‐
line with metallic additives, e. g. manganese or
iron, or permanent damage to the catalytic con‐
verter and other components.◀
Do not refuel with ethanol
Do not refuel with E85, i.e., fuel with an
ethanol content of 85 %, or with Flex Fuel, as this
would damage the engine and fuel supply sys‐
tem.◀
Required fuel
Super premium gasoline/AKI 93
This gasoline is highly recommended.
Gasoline with lower AKI
However, you may also use gasoline with less
AKI.
The minimum AKI Rating is 91.
If you use gasoline with this minimum AKI Rat‐
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.Minimum fuel grade
Do not use any gasoline below the mini‐
mum fuel grade as this may impair engine per‐
formance.◀
Use high-quality brands
Field experience has indicated significant differ‐
ences in fuel quality: volatility, composition, ad‐
ditives, etc., among gasolines offered for sale in
the United States and Canada.
Fuels containing up to and including 10 % etha‐
nol or other oxygenates with up to 2.8 % oxygen
by weight, that is, 15 % MTBE or 3 % methanol
plus an equivalent amount of co-solvent, will not
void the applicable warranties with respect to
defects in materials or workmanship.
Minimum fuel grade
The use of poor-quality fuels may result in
driveability, starting and stalling problems es‐
pecially under certain environmental conditions
such as high ambient temperature and high al‐
titude.
Should you encounter driveability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may result in unscheduled maintenance.◀Seite 240MobilityFuel240

4.Insert the sealant bottle on the compressor
housing in an upright position.5.Screw the filling hose of the sealant bottle
onto the valve of the defective wheel.6.With the compressor switched off, insert the
plug into the power socket inside the vehi‐
cle.7.With the ignition turned on or the engine
running, switch on the compressor.
Let the compressor run for approx. 3 to 8 mi‐
nutes to fill the tire with sealant and achieve a
tire inflation pressure of approx. 2.5 bar.
While the tire is being filled with sealant, the in‐
flation pressure may sporadically reach approx.
5 bar. Do not switch off the compressor in this
phase.
Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes
may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Switch off the compressor after 10 mi‐
nutes
Do not allow the compressor to run longer than
10 minutes; otherwise, the device will overheat
and may be damaged.◀
If a tire pressure of 2 bar is not reached:
1.Switch off the compressor.2.Unscrew the filling hose from the wheel.3.Drive forward and back to distribute the
sealant in the tire.4.Inflate the tire again using the compressor.
