& WARNING Risk of accident due to repea-
ted pressure drop in the tyres
The wheels, valves or tyres could be damaged.
Too low a tyre pressure can lead to the tyres
bursting.
Examine the tyres for foreign objects.
#
Check whether the tyre has a puncture
#
or the valve has a leak.
If you are unable to rectify the damage,
#
contact a qualified specialist workshop.
Information on the recommended tyre pressure
for the vehicle's factory-fitted tyres can be found
on the tyre pressure table on the inside of the
socket flap (
page 546).
/
Use a suitable pressure gauge to check the tyre
pressure. The outer appearance of a tyre does not
permit any reliable conclusion about the tyre pres-
sure.
Only correct tyre pressures when the tyres are
cold. Conditions for cold tyres:
The vehicle has been parked with the tyres out
R
of direct sunlight for at least three hours.
The vehicle has travelled less than 1.6 km.
R
The vehicle's tyres heat up when driving. As the
temperature of the tyres increases, so too does
the tyre pressure.
Vehicles with a tyre pressure monitoring system:
you can also see the tyre pressure in the driver's
display (
page 547).

Notes on trailer operation
Always inflate the rear axle tyres to the recom-
mended tyre pressures on the tyre pressure table
for increased load.
Tyre pressure table
The tyre pressure table is on the inside of the
socket flap.
F243 0059 02
The tyre pressure table shows the recommended
tyre pressure for all tyres approved for this vehi-
cle. The recommended tyre pressures apply for
cold tyres under various operating conditions, i.e.
loading and/or speed of the vehicle.
If one or more tyre sizes precede a tyre pressure,
the tyre pressure information following is only
valid for those tyre sizes.
