Vehicle equipment
This chapter describes all standard, country-spe‐
cific and special equipment available for the
model series. It may therefore describe equip‐
ment and functions which are not installed in
your vehicle, for example on account of the op‐
tional equipment selected or the country specifi‐
cation. This also applies to safety-relevant func‐
tions and systems. Please comply with the
relevant laws and regulations when using the
corresponding functions and systems.
Tyre inflation pressure
General
A tyre's condition and inflation pressure influence
the following:
▷ Lifetime of the tyre.
▷ Driving safety.
▷ Driving comfort.
▷ Fuel consumption.
Safety note
WARNING
A tyre with too little or no tyre inflation pressure
can heat up significantly and sustain damage.
Driving properties, for example steering and
braking, will be impaired as a result. There is a
danger of accidents. Check the tyre inflation
pressure regularly and adjust as necessary, for
example twice a month or before any long jour‐
ney.
Tyre inflation pressure
information
On the door pillar
The tyre inflation pressures are shown on the
door pillar of the driver's door.
The tyre inflation pressure data applies to the
tyre sizes and recommended tyre makes which
have been classified by the vehicle manufacturer
as suitable for the respective vehicle type.
If the tyre's speed code cannot be found, then
the tyre inflation pressure for the corresponding
tyre size applies.
The tyre inflation pressures stated for the re‐
spective load conditions will apply, in accordance
with the vehicle's actual load condition. Example:
for a partially loaded vehicle, the optimum tyre in‐
flation pressure is the one stated for a partially
loaded vehicle.
When the vehicle is partially loaded, the lowest
possible fuel consumption can be achieved with
the ECO tyre inflation pressure.
More information regarding wheels and tyres can
be obtained from a Service Partner of the manu‐
facturer or another qualified Service Partner or a
specialist workshop.
