Example: tyre pressure table on the fuel filler flap
You will find the recommended tyre pressures
for various operating conditions on the inside of
your vehicle's fuel filler flap (
under "Tyre pressure tables" (
If tyre sizes are not specified, the tyre pressures
stated on the tyre pressure information table
apply for all tyres approved for this vehicle.
If a tyre size precedes a tyre pressure, the fol-
lowing tyre pressure information is only valid for
that tyre size.

The tyre pressure information table may also
state tyre pressures for different vehicle loads.
These are defined in the tyre pressure informa-
tion table as different numbers of passengers
and amounts of luggage. The actual number of
seats may vary – for more information, please
refer to the vehicle's registration documents.
The tyre pressure values given for partly laden
vehicles are minimum values which offer you
good ride comfort. They are not for towing trail-
ers.
You can also use the tyre pressure values for a
fully laden vehicle. These are always permitted
and admissible. However, in a partially laden
vehicle, the ride is not as comfortable and fuel
consumption is only minimally reduced. In addi-
tion, wear is greater in the middle of the tyre
tread.
For towing trailers, the applicable value for the
rear tyres is the maximum tyre pressure value
stated in the table inside the fuel filler flap.
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.
On vehicles fitted with the electronic tyre pres-
sure monitor, the tyre pressure can be checked
using the on-board computer.
Set the correct tyre pressure before loading the
vehicle. Once the vehicle is laden, check the tyre

If possible, only correct tyre pressures when the
tyres are cold.
The tyres are cold:

Depending on the ambient temperature, the
speed at which you are driving and the load on
the tyres, the tyre temperature and thus the tyre
pressure changes by approximately 10 kPa
(0.1 bar/1.5 psi) per 10 †. Take this into
account when checking the pressure of warm
tyres. Only correct the tyre pressure if it is too
low for the current operating conditions.
Driving with a tyre pressure that is too high or
too low:

General notes
In vehicles with a tyre pressure monitor system,
the vehicle's wheels have sensors fitted which
monitor the tyre pressure in all four tyres. The
tyre pressure monitor warns you if the pressure
drops in one or more of the tyres. The tyre pres-
sure monitor only functions if the corresponding
sensors are fitted to all wheels.
if the vehicle has been parked with the tyres
out of direct sunlight for at least three hours
and
if the vehicle has not been driven further than
1.6 km

has a negative effect on handling character-
istics and thus driving safety (e.g. due to
