R Snow ch ains are on ly permissible for cer tain
wheel/tyre combinations. You can obtain
information about this from a Mercedes-Benz
Service Cent re.
R For saf etyre asons, on lyuse sn ow chainsthat

with the same quality standard.
R If sn ow ch ains are fitted, the maximum per‐
missible speed is 50 km/h.
R Vehicles with le vel control: if snowchains
are fitted, only drive at raised vehicle le vel.
% You can permanently limit the maximum

WARNING Risk of accident due toinsuf‐
fi cient or excessive tyre pressure
Underinfla ted or overinfla ted tyres pose the
fo llowing risks:
R The tyres may bur st, especially as the
load and vehicle speed increase.
R The tyres may wearexc essively and/or
une venly, which may greatlyimpair tyre
traction.
R The driving characteristics, as well as
st eering and braking, may be greatly
impaired. #
Comply with there commended tyre
pressure and check the tyre pressure of
all tyres including the spare wheel regu‐
larly:
R at least once a month
R when the load changes R
before embarking on a lon ger journey
R if operating conditions change, e.g. off-
ro ad driving #
Adjust the tyre pressure as necessar y. Ty
re pressure which is too high or too low can:
R Shor tenth e service life of the tyres.
R Cause increased tyre damage.
R Adversely af fect driving characteristics and
th us driving saf ety, e.g. due toaquaplaning. &
WARNING Risk of accident from repea‐
te d tyre pressure drop
If th e tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged.
Insuf ficient tyre pressure can cause the tyres
to bur st. #
Inspect the tyre for signs of fore ign
objects. #
Check whe ther the wheel or valve has a
leak. 286

Ifyo u are unable torectify the damage,
conta ct aqualified specialist workshop. Information on
there commended tyre pressure
fo rth eve hicle's factor y-fitted tyres can be found
on the tyre pressure table on the inside of the
fuel filler flap (/ page 287).
Use a suitable pressure gauge tocheck the tyre
pressure. The outer appearance of a tyre does
not permit any reliable conclusion about the tyre
pressure.
Ve hicles with a tyre pressure monitoring sys‐
te m: you can also check the tyre pressure using
th e on-board computer.
Only cor rect tyre pressures when the tyres are
cold. Conditions for cold tyres:
R The vehicle has been par ked with the tyres
out of direct sunlight for at least thre e hours.
R The vehicle has tr avelled less than 1.6 km.
A rise in the tyre temp erature of 10°C increases
th e tyre pressure byappr ox.10 kPa (0.1 bar/
1. 5 psi). Take this into account when checking
th e tyre pressure of warm tyres. Ty
re pressure table The tyre pressure
table is on the inside of the
fuel filler flap. The tyre pressure
table sho ws there commended
tyre pressure for all tyres appro vedfo rth is vehi‐
cle. The recommended tyre pressures apply for
cold tyres under various operating conditions,
i.e. loading and/or speed of theve hicle. If one or more tyre sizes precede a tyre pres‐
sure,
the tyre pressure information following is
only valid forth ose tyre sizes.
If th e preceding tyre sizes are complemented by
th e+ symbol, the tyre pressure information
fo llowing sho wsalternative tyre pressures.
These tyre pressures may impr oveyour vehicle's
ri de comfort. Fuel consum ption may then
increase slightl y.
The load conditions "partially laden" and "fully
laden" are defined in theta ble for dif fere nt num‐
be rs of passengers and amounts of luggage. The
actual number of seats may dif fer from this.

The sy stem checks the tyre pressure and the

New tyre pressure sensors, e.g. in winter tyres,
are automatically

The tyre pressure and the tyre temp erature
appear in the multifunction display
