Gas gauge
The display » Fig. 19 only works if the ignition is switched on.
The capacity of the natural gas fuel tank is approximately 15 kg.
If this fuel level reaches the reserve area, in the display the icon and a re-
quest for natural gas refuelling is displayed.
NoteThe arrow next to the symbol within the fuel gauge displays the installation
location of the fuel filler on the right side of the vehicle.

WARNINGFor the vehicle systems to function correctly, and thus for safe driving,
there must be sufficient fuel in the tank. Never drain the fuel tank com-
pletely – risk of accident!
CAUTION
Never drive until the fuel tank is completely empty! Irregular supply of fuel can
cause misfiring, which can result in damage to parts of the engine and the ex-
haust system.
Note
■ After filling up, it’s possible that during dynamic driving (e.g. numerous
curves, braking, driving downhill and climbing a steep hill) the fuel gauge indi-
cates a fraction less.■
The arrow
next to the symbol
within the fuel gauge displays the installa-
tion location of the fuel filler on the right side of the vehicle.

■Ensure that no part of the leather is soaked through during cleaning and
that no water gets into the seams - There is risk of damaging the leather!
■ Do not clean the roof panelling with a brush – risk of damage to the surface
of the panelling. ■ Do not use leather cleaners, floor wax, shoe cream, stain remover or similar
agents on Alcantara ®
seat upholstery.
■ Some clothing fabrics (e.g. dark denim) do not have sufficient colour fast-
ness - this could lead to clearly visible discolouration on the upholstery. This
is not a defect in the fabric. ■ Sharp objects on garments (e.g. zips, rivets, sharp- edged belts) can dam-
age the upholstery fabrics in the vehicle. Such damage will not be recognised
as a justified complaint.■
Plastic parts
■ Do not attach scents or air fresheners to the dash panel – risk of damage to
the dash panel.
■
Windows
■ Do not attach any stickers to the filaments or glass antenna - there is risk
of damage.
■
Covers on electrically heated seats ■ Do not clean either with water or with other liquids - There is a risk of dam-
age to the heating system. ■ Do not dry by switching on the heating.
■
Seat belts
■ After cleaning the belts, allow them to dry before retracting them.
Note
During vehicle use, some minor changes may become visible on the leather
and Alcantara ®
(due to e.g. folds, discolouration).Inspecting and replenishing

Introduction

fuel
This chapter contains information on the following subjects:
Petrol and diesel refuelling

Unleaded petrol

Diesel fuel

Refuel CNG (compressed natural gas)
251
CNG
252
The correct grades of fuel for your vehicle are stated on a sticker affixed to the
inside of the fuel filler flap » Fig. 285.
The fuel tank has a capacity of about 50 litres, including a reserve of approx.
6 litres .
WARNINGThe fuel and fuel vapours are explosive - risk to life! 248General Maintenance

CAUTIONThe following instructions must be observed, otherwise there is a risk of dam-
age to the engine and to the exhaust system.■
If a different fuel other than diesel fuel, which complies to the above men-
tioned standards (e.g. petrol) is used, do not start the engine or switch on the
ignition!
■
The biofuel RME must not be used!
CAUTION
Diesel fuel additives■The diesel fuel in accordance with the prescribed standards meets all the
conditions for a smooth running engine. Therefore, we recommend that you do
not add any fuel additives to the diesel - - there is a risk of engine damage or
damage to the exhaust system.
Refuel CNG (compressed natural gas)
Fig. 288
Natural gas filler tubes
Read and observe
and on page 248 first.
Refuel with natural gas under the following conditions. The vehicle is unlocked.
The engine and the ignition are switched off.
The auxiliary heating and ventilation is switched off » page 109.
Natural gas refuelling may vary from station to station. If refuelling with natu-
ral gas at a station is unfamiliar to you, get someone to instruct you or allow
the fuelling operation to be carried out by the station staff.
Refuelling operation
›
Open the fuel filler flap.
› Remove cap A
» Fig. 288 in the direction of the arrow and insert connector
for the refuelling system into filler neck B.
The fuel tank is full when the compressor of the refuelling system automati-
cally switches off.›
Check that sealing ring
C
» Fig. 288 has remained inserted in filler neck
B
. If
the sealing ring has slipped on the connector, reinsert it into the filler neck.
›
Insert cap
A
into the filler neck and close the fuel filler flap until it locks into
place.
The natural gas refuelling systems have an overfill protection relating to the
outdoor temperature. At very high outside temperatures, it may happen that
the gas tank may not be fully refuelled.
If the vehicle is parked directly after a refuelling operation, on restart the
pointer of the gas gauge may not show exactly the same level as immediately
after the filling process. This is not a leak in the system, but a reduction in
pressure due to the cooling of the gas in the gas tank after refuelling.
The maximum lifetime of the gas tank is 20 years.
The capacity of the natural gas fuel tank is approximately 15 kg.
WARNING■
Natural gas is highly explosive and highly flammable.■When refuelling, never get into the vehicle. If you have to get into your
vehicle in exceptional cases, touch a metal surface before you touch the
filling coupling again. Otherwise, electrostatic discharging may occur -
There is a risk of fire!
Note
During the filling process sounds are heard which are harmless. If you are un-
sure which service station staff to use, ask the petrol station staff.251Inspecting and replenishing

The approved tyres and rim sizes for your vehicle are listed in the vehicle's
technical documentation (the so called COC document) and this also states the
declaration of conformity.
Rating plate
The type plate » Fig. 342 is located at the bottom of the B-pillar on the right-
hand driver's side.
The type plate contains the following data. Vehicle manufacturers
Vehicle identification number (VIN)
Maximum permissible gross weight
Maximum permissible towed weight (towing vehicle and trailer)
Maximum permissible front axle load
Maximum permissible rear axle load
Vehicle identification number (VIN)
The vehicle identification number - VIN (vehicle body number) is stamped into
the engine compartment on the right hand suspension strut dome. This num-
ber is also located on a sign on the lower left hand edge below the windscreen
(together with a VIN bar code), and on the type plate.
The VIN number can also be displayed in the Infotainment menu

.
Engine number
The engine number (three-digit identifier and serial number) is stamped on the
engine block.
Supplementary Information (applies to Russia)
The full type approval number of the means of transport is indicated in the
registration documents, field 17.
Maximum permissible trailer weight
The listed maximum allowable trailer weight is only valid for altitudes up to
1000 m above sea level.
The engine output falls as the height increases, as does the ability to climb.
Therefore, for every additional 1000 m in height (or part), the maximum per-
missible towed weight must be reduced by 10%.
The towed weight is made up of the actual weights of the loaded towing vehi-
cle and the loaded trailer.
123456WARNINGDo not exceed the specified maximum permissible weights – risk of acci-
dent and damage!
Operating weight
This value is only a guide value and corresponds to the lowest possible operat-
ing weight without any equipment added that would also increase the weight
(e.g. air conditioning, emergency or spare wheel etc.). It also includes a weight
allowance for the driver (75 kg), the weight of the operating fluids, the tool kit
and a fuel tank filled to 90 % capacity.
