RefuelingVehicle features and options
This chapter describes all standard, country-spej
cific and optional features offered with the series.
It also describes features that are not necessarily
available in your vehicle, e. g., due to the selected
options or country versions. This also applies to
safety-related functions and systems. When usj
ing these functions and systems, the applicable laws and regulations must be observed.
General information
Follow the fuel recommendation, refer to
page 224, prior to refueling.
A sufficient amount of fuel must be added to opj
erate the Range Extender. When the Range Exj
tender is activated, the current charge state is
maintained. The vehicle has a greater range.
Do not refuel unless the engine is at a standstill
and the selector lever is in position P/N, otherj
wise the buildup of pressure may cause the fuel
nozzle to shut off prematurely.
Safety information
NOTE
With a driving range of less than
30 miles/50 km the engine may no longer have
sufficient fuel. Engine functions are not enj
sured anymore. There is a risk of damage to
property. Refuel promptly.
Tank vent
Concept
The vehicle is equipped with a special fuel tank.
The fuel tank is designed for special requirej ments that arise from operation with the RangeExtender.
General information In the fuel tank, excess pressure can build updue to gasoline vapors which are dissipated bej
fore the fuel cap is opened.
Overview The button is located on the driver's floor area.

Tire inflation pressure
General information The tire inflation pressure and tire characteristics
influence the following:
'xThe service life of the tires.'xRoad safety.'xDriving comfort.'xDriving dynamics.'xFuel consumption.
Safety information
WARNING
A tire with too little or no tire inflation pressure
may heat up significantly and sustain damage.
This will have a negative impact on aspects of handling, such as steering and braking rej
sponse. There is a risk of an accident. Regularly
check the tire inflation pressure, and correct it as needed, for instance twice a month and bej
fore a long trip.
Tire inflation pressure specifications
In the tire inflation pressure table
The tire inflation pressure table, refer to
page 227, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pressure values apply to tire sizes approved by the manuj
facturer of the vehicle for the vehicle type.
To identify the correct tire inflation pressure,
please note the following:'xTire sizes of your vehicle.
Checking the tire inflation pressure
General information Tires heat up while driving. The tire inflationpressure increases with the tire temperature.
Tires have a natural, consistent loss of tire inflajtion pressure.
The displays of inflation devices may under-read by up to 0.1 bar/2 psi.
Checking using tire inflation pressure
specifications in the tire inflation pressure
table
The tire inflation pressure specifications in the tire inflation pressure table only relate to coldtires or tires at the same temperature as the amjbient temperature.
Only check the tire inflation pressure levels when
the tires are cold, i.e.:
'xDriving range of max. 1.25 miles/2 km has not
been exceeded.Seite 226MOBILITYWheels and tires226
Online Edition for Part no. 01402989267 - II/18

'xIf the vehicle has not moved again for at least2 hours after a trip.1.Determine, refer to page 226, the intended
tire inflation pressure levels for the mounted
tires.2.Check the tire inflation pressure in all four
tires, using a pressure gage, for example.3.Correct the tire inflation pressure if the curj
rent tire inflation pressure value deviates from the specified value.4.Check whether all valve caps are screwed
onto the tire valves.
After correcting the tire inflation pressure
For run-flat tires: reinitialize run-flat tires.
For the Tire Pressure Monitor TPM: reset the Tire Pressure Monitor TPM.
Tire fill pressures
To achieve optimum driving comfort, note the
pressure specifications in the Tire inflation presj
sure table, refer to page 227, and adjust as
needed.
These pressure values can also be found on the tire inflation pressure label on the driver's side on
the rear door.

Tire age
Recommendation Regardless of the tire tread, replace tires at least
every 6 years.
Manufacture date
You can find the manufacture date of the tire on the tire's sidewall.DesignationManufacture dateDOT 

Tire tread
Summer tires
Do not drive with a tire tread of less than
0.12 in/3 mm, otherwise there is an increased
risk of hydroplaning.
Winter tires
Do not drive with a tire tread of less than
0.16 in/4 mm, as such tires are less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the tire's
circumference and have the legally required minj imum height of 0.063 inches/1.6 mm.
The positions of the wear indicators are marked on the tire sidewall with TWI, Tread Wear Indicaj
tor.
Tire damage
General information
Inspect your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Driving over rough or damaged road surfaces, as
well as debris, curbs and other obstacles can
cause serious damage to wheels, tires and susj
pension parts. This is more likely to occur with
low-profile tires, which provide less cushioning
between the wheel and the road. Be careful to
avoid road hazards and reduce your speed, esj
pecially if your vehicle is equipped with low-proj file tires.
Indications of tire damage or other vehicle malj
functions:'xUnusual vibrations.'xUnusual tire or running noises.'xUnusual handling such as a strong tendency
to pull to the left or right.
Damage can be caused by the following situaj
tions, for instance:
'xDriving over curbs.'xRoad damage.'xTire inflation pressure too low.'xVehicle overloading.'xIncorrect tire storage.
Safety information
WARNING
Damaged tires can lose tire inflation pressure,
which can lead to loss of vehicle control. There is a risk of an accident. If tire damage is susj
pected while driving, immediately reduce speed
and stop. Have wheels and tires checked. For
this purpose, drive carefully to the nearest dealj erss service center or another qualified servicecenter or repair shop. Have vehicle towed or
transported as needed. Do not repair damaged
tires, but have them replaced.
WARNING
Tires can become damaged by driving over obj
stacles, e.g., curbs or road damage, at high
speed. Larger wheels have a smaller tire cross- section. The smaller the tire cross-section, the
higher the risk of tire damage. There is a danj
ger of accidents and property damage. If possij
ble, drive around obstacles, or drive over them
slowly and carefully.
