396 Wheels and tyres
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
fuel filler flap ( page 396).
/
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
pressure.
Only correct tyre pressures when the tyres are
cold. Conditions for cold tyres:
The vehicle has been parked with the tyres
R
out 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 tyre pressure monitoring sys‐
tems: you can also see the tyre pressure in the
driver's display.
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
fuel filler flap.
If one or more tyre sizes precede a tyre pres‐
sure, the following tyre pressure information is
only valid for those tyre sizes and their respec‐
tive load condition.
If the preceding tyre sizes are complemented by
the + symbol, the tyre pressure information
following shows alternative tyre pressures. Fuel
consumption may then increase slightly.
