#
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. #
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 526).
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.

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
tyre temp erature of the tyres fitted totheve hicle
by means of a tyre pressu resensor.
New tyre pressure sensors, e.g. in winter tyres,
are automatically taught-in during thefirs t jour‐
ney they are used. The tyre pressure and
the tyre temp erature
appear in the multifunction display
(/ page 528).
If th ere is a subs tantial pressure loss or if the
tyre temp erature is excessive, you will be
wa rned in thefo llowing ways:
R via display messa ges (/ page613)
R viatheh warning lamp in the instrument

The tyre pressu remonitoring sy stem is only an
aid. It is the driver's responsibility toset the tyre
pressure tothere commended cold tyre pressure

nction of the ty repressure loss warning
sy stem
The tyre pressure loss warning sy stem warnsthe
driver bymeans of display messa ges when there
is a se vere tyre pressu reloss.
Af ter a change in tyre pressure, a wheel rotation
or a tyre change, or if you ha verefitted wheels
or tyres, the tyre pressure loss warning sy stem
has tobe restar ted (/ page 533).
The tyre pressure loss warning sy stem does not
re place the need toregularly check the tyre
pressures.
Sy stem limitations
The sy stem may be impaired or may not function
particular lyin thefo llowing situations:
R incor rectly set tyre pressure
R sudden pressure loss caused, forex ample,
by afo re ign object penetrating the tyre
R steady pressure loss in se veral tyres The sy
stem has a restricted or del ayed function
particularly in thefo llowing situations:
R poor ground cond itions, e.g. snow or gr avel
R driving with snow chains
R when adopting a very sporty driving style
with high cornering speeds or sudden accel‐
eration
R driving with a very heavy or lar getrailer
R driving wi tha high load
